Simple Summary: Liver transplantation (LT) is one of the primary treatments for hepatocellular carcinoma (HCC) and significantly improves patient survival. However, the application of LT for HCC faces challenges owing to advancements in cancer-specific treatments and increased patient comorbidities. This review explores the current controversies and advancements in LT for HCC, focusing on managing comorbidities, the impact of frailty, selection criteria, the role of radiology, and the potential use of immunotherapy. We emphasize the importance of immunosuppression management and surveillance for HCC recurrence. A multidisciplinary approach is crucial to optimize the outcomes of patients with HCC undergoing LT, ensuring comprehensive care and improved survival rates. Liver transplantation (LT) remains one of the most effective treatments for hepatocellular carcinoma (HCC) and significantly enhances patient survival. However, the application of LT for HCC faces challenges owing to advancements in cancer-specific treatment modalities and the increased burden of patients' comorbidities. This narrative review explores current controversies and advancements in LT for HCC. Key areas of focus include the management of comorbidities and patient education by advanced practice nurses, impacts of frailty on waitlists and post-LT outcomes, selection criteria for LT in the era of new downstaging tools, role of radiology in patient selection, and implications of potential immunotherapy use both before and after LT. Additionally, the importance of immunosuppression management with strategies aimed at minimizing rejection while considering the risk of HCC recurrence and the role of surveillance for HCC recurrence is highlighted. This review also underscores the importance of a multidisciplinary approach for optimizing outcomes in patients with HCC undergoing LT. [ABSTRACT FROM AUTHOR]

Simple Summary: This study focuses on Stage IIIA-N2 non-small cell lung cancer (NSCLC), which occurs when lung cancer has spread to lymph nodes in the centre of the chest but not to distant parts of the body. This type of cancer is difficult to treat, and survival rates remain low despite advances in therapy. The research is based on real-world data from Guy's Thoracic Cancer Database and aims to enhance our understanding of patient outcomes and identify important factors that impact survival and disease progression. By examining various treatment strategies, the study aims to offer insights that could help tailor treatment approaches to individual patients. The findings underscore the need for personalised care and the potential benefits of incorporating newer therapeutic options, ultimately leading to better survival outcomes for patients with this challenging form of lung cancer. Background: Stage IIIA-N2 non-small cell lung cancer (NSCLC) poses a significant clinical challenge, with low survival rates despite advances in therapy. The lack of a standardised treatment approach complicates patient management. This study utilises real-world data from Guy's Thoracic Cancer Database to analyse patient outcomes, identify key predictors of overall survival (OS) and disease-free survival (DFS), and address the limitations of randomised controlled trials. Methods: This observational, single-centre, non-randomised study analysed 142 patients diagnosed with clinical and pathological T1/2 N2 NSCLC who received curative treatment from 2015 to 2021. Patients were categorised into three groups: Group A (30 patients) underwent surgery for clinical N2 disease, Group B (54 patients) had unsuspected N2 disease discovered during surgery, and Group C (58 patients) received radical chemoradiation or radiotherapy alone (CRT/RT) for clinical N2 disease. Data on demographics, treatment types, recurrence, and survival rates were analysed. Results: The median OS for the cohort was 31 months, with 2-year and 5-year OS rates of 60% and 30%, respectively. Group A had a median OS of 32 months, Group B 36 months, and Group C 25 months. The median DFS was 18 months overall, with Group A at 16 months, Group B at 22 months, and Group C at 17 months. Significant predictors of OS included ECOG performance status, lymphovascular invasion, and histology. No significant differences in OS were found between treatment groups (p = 0.99). Conclusions: This study highlights the complexity and diversity of Stage IIIA-N2 NSCLC, with no single superior treatment strategy identified. The findings underscore the necessity for personalised treatment approaches and multidisciplinary decision-making. Future research should focus on integrating newer therapeutic modalities and conducting multi-centre trials to refine treatment strategies. Collaboration and ongoing data collection are crucial for improving personalised treatment plans and survival outcomes for Stage IIIA-N2 NSCLC patients. [ABSTRACT FROM AUTHOR]

Simple Summary: We aimed to evaluate the role of adjuvant chemotherapy in patients who undergo pneumonectomy for pN1 NSCLC. We found no significant differences after 5 years between two cohorts (adjuvant CT and no adjuvant CT) in terms of the overall survival (p: 0.31), cancer-specific survival (p: 0.59), disease-free survival (p: 0.94), and relapse rate (p: 0.76). Patients with pN1 NSCLC that was completely resected through pneumonectomy and radical lymphadenectomy may represent a particular cohort, which could be strictly followed up without adjuvant chemotherapy. Introduction: We aimed to assess our 25-year experience in order to evaluate the role of adjuvant chemotherapy in patients who undergo pneumonectomy for pN1 NSCLC. Materials and Methods: We retrospectively reviewed the outcomes and medical records of patients undergoing pneumonectomy for NSCLC with pathological diagnosis of pN1, excluding all patients who underwent neoadjuvant treatment. We compared patients treated with adjuvant chemotherapy with patients who did not undergo neoadjuvant treatment during a follow-up soon after surgery. Gray's test was used to assess differences in the cumulative incidence of relapse or CSS between the different groups. Kaplan–Meier methods were used for drawing overall survival (OS) plots. In order to assess differences in survival between the groups, the log-rank test was used. The cumulative incidence of relapse, CSS, and OS were calculated at 1, 2, 3, 4, and 5 years of follow-up. Results: The 30-day and 90-day mortality rates of our cohort were 6% and 11,6%. Excluding the first three months after surgery (deaths linked to postoperative comorbidity), after 5 years we found no significant differences between the two cohorts (adjuvant CT and no adjuvant CT) in terms of the overall survival (OS) (p: 0.31), cancer-specific survival (CSS) (p: 0.59), disease-free survival (DFS) (p: 0.94), and relapse rate (p: 0.76). Conclusions: Patients with pN1 NSCLC that was completely resected through pneumonectomy and radical lymphadenectomy may represent a particular cohort, which could be strictly followed up without adjuvant chemotherapy.

Simple Summary: Melanoma is the deadliest of all skin cancers. Therapy paradigms in cutaneous melanoma have changed significantly over the past 20 years, following both changes in the initial staging work-up of melanoma as well as in the available therapies. Regional recurrences after initial surgery are normally treated with nodal basin resection. However, some regional recurrences may present as bulky masses that can pose significant challenges in the treatment and control of the disease. It is well established that radiation therapy (RT) plays a role in locoregional control of malignancies in general. This review will attempt to discuss evidence for radiation therapy's role in reducing regional recurrence in the adjuvant setting in melanoma, identify adjuvant systemic therapy options, discuss systemic therapy–radiation therapy combinations, and identify paradigms and emerging evidence for the use of radiation therapy after neoadjuvant systemic therapy strategies are employed. In the landscape of Stage III locoregionally advanced cutaneous melanoma treatment, the post-immunotherapy era has sparked a number of questions on the management of the nodal basin. However, much of the available literature is not focused on radiation therapy as an adjuvant therapy. This literature review aims to illuminate the evidence surrounding radiation therapy's potential to mitigate regional recurrences in the adjuvant setting for melanoma. Additionally, it seeks to identify adjunct systemic therapy options and explore the synergy between systemic therapy and radiation. Despite strides in surgical techniques and systemic therapies, controlling regional Stage III melanoma remains a formidable clinical hurdle. While historical data strongly suggest the efficacy of adjuvant radiation therapy in reducing regional recurrence risk, its evaluation predates the advent of MAPK pathway inhibitors and robust immunotherapy options. Notably, clinical trials have yet to definitively demonstrate a survival advantage with adjuvant radiation therapy. Additional research should focus on refining the definition of high risk for regional recurrence through gene expression profiling or tumor immune profiling scores and elucidate the optimal role of adjuvant radiation therapy in patients treated with neoadjuvant systemic therapy.

Simple Summary: Oral cancer, particularly oral squamous cell carcinoma (OSCC), is a widespread health problem with limited treatment options and poor survival rates. Metformin, a common medication for managing diabetes, has recently shown promise as a potential treatment for various cancers, including OSCC. This review examines the potential benefits of repurposing metformin to treat oral cancer. Studies have shown that metformin can reduce the growth of cancer cells, induce cancer cell death, and improve the effectiveness of existing treatments. It works by affecting several pathways involved in cancer development, such as those related to cell energy and inflammation. However, using metformin for cancer treatment comes with challenges, including possible side effects and interactions with other medications. More research and clinical trials are needed to understand how metformin can be effectively used in cancer treatment and to ensure its safety. If proven effective, metformin could provide a new, cost-effective option for treating oral cancer, potentially improving outcomes and quality of life for patients. Oral cancer, particularly oral squamous cell carcinoma (OSCC), is a significant global health challenge because of its high incidence and limited treatment options. Major risk factors, including tobacco use, alcohol consumption, and specific microbiota, contribute to the disease's prevalence. Recently, a compelling association between diabetes mellitus (DM) and oral cancer has been identified, with metformin, a widely used antidiabetic drug, emerging as a potential therapeutic agent across various cancers, including OSCC. This review explores both preclinical and clinical studies to understand the mechanisms by which metformin may exert its anticancer effects, such as inhibiting cancer cell proliferation, inducing apoptosis, and enhancing the efficacy of existing treatments. Preclinical studies demonstrate that metformin modulates crucial metabolic pathways, reduces inflammation, and impacts cellular proliferation, thereby potentially lowering cancer risk and improving patient outcomes. Additionally, metformin's ability to reverse epithelial-to-mesenchymal transition (EMT), regulate the LIN28/let-7 axis, and its therapeutic role in head and neck squamous cell carcinoma (HNSCC) are examined through experimental models. In clinical contexts, metformin shows promise in enhancing therapeutic outcomes and reducing recurrence rates, although challenges such as drug interactions, complex dosing regimens, and risks such as vitamin B12 deficiency remain. Future research should focus on optimizing metformin's application, investigating its synergistic effects with other therapies, and conducting rigorous clinical trials to validate its efficacy in OSCC treatment. This dual exploration underscores metformin's potential to play a transformative role in both diabetes management and cancer care, potentially revolutionizing oral cancer treatment strategies.

Simple Summary: This meta-analysis compared PET imaging (PET/CT and PET) against MRI in detecting a residual tumor or recurrence in patients with nasopharyngeal carcinoma (NPC) at the primary site, retrieving studies that included patients who had both types of scans within a short period after treatment. According to the collected evidence, PET/CT and PET are more sensitive compared to MRI in detecting tumors. However, both methods were equally able to correctly identify patients who did not have tumors. These findings suggest that PET imaging might be more reliable for detecting tumor recurrence or residual disease, which could help doctors make better decisions about patient care and follow-up after treatment for NPC. Background: This meta-analysis compared the diagnostic performance of [18F] fluorodeoxyglucose ([18F]FDG) positron emission tomography/computed tomography (PET/CT) or PET versus Magnetic resonance imaging (MRI) in detecting recurrence or residual tumors at the primary site in patients with nasopharyngeal carcinoma (NPC). Methods: A comprehensive literature search was conducted in the PubMed/MEDLINE and CENTRAL databases to find studies with at least 20 patients with NPC undergoing both [18F]FDG PET/CT (or [18F]FDG PET) and MRI for detecting recurrence or assessing residual disease at the primary site. The pooled sensitivity and specificity of PET/CT and MRI were calculated with 95% confidence intervals (CIs) and compared. Results: Five studies, including 1908 patients (six patient groups), were included. PET imaging had higher sensitivity [93.3% (95% CI: 91.3–94.9%); I2 = 52.6%] compared to MRI [80.1% (95% CI: 77.2–82.8%); I2 = 68.3%], but the specificity of the two modalities was similar: 93.8% (95% CI: 92.2–95.2%; I2 = 0%) for PET/CT and 91.8% (95% CI: 90.1–93.4%; I2 = 94.3%) for MRI. The areas under the curve (AUCs) for PET/CT and MRI were 0.978 and 0.924, respectively, without significant difference (p = 0.23). Conclusions: This meta-analysis suggests that [18F]FDG PET imaging and MRI do not significantly differ in diagnostic performance. Nevertheless, [18F]FDG PET imaging shows higher sensitivity than MRI.

Simple Summary: The survival of glioblastoma (GBM) patients remains at just 12–15 months with a 5% 5 year survival despite them undergoing a harsh and brutal treatment regimen involving surgery, radiation and chemotherapy. This is because GBMs are impossible to completely resect and almost always recur at the borders of the resection margin, while the presence of the blood–brain barrier limits the amount of chemotherapy that can access the brain, requiring the patient to receive high and extremely toxic doses of chemotherapy. In this study, we demonstrate that local delivery of the chemotherapeutic drug irinotecan directly into the border of the resection margin offers a safe route of administration with none of the normal side effects associated with traditional chemotherapy. Glioblastomas are impossible to completely resect and almost always recur at the borders of the resection margin. There is no established chemotherapy regimen available to patients who recur, while systemic treatment is hampered by the blood–brain barrier. Here, we report on the first evaluation in humans of the intraparenchymal injection of irinotecan into the resection cavity after surgical resection of recurrent glioblastoma patients. The cytotoxicity of irinotecan was compared to SN-38 in primary cells from recurrent glioblastoma patients. Irinotecan was injected at multiple (~30) sites of the resection cavity wall at a depth of 3 to 5 mm. SN-38 was more cytotoxic than irinotecan at concentrations below 1 µM due to enzyme kinetics. The intraparenchymal administration of irinotecan was safe, with good wound healing and an absence of swelling, inflammation, or pseudo-abscess formation. The median survival post irinotecan administration was 32.6 weeks. The median overall survival was 30.5 months, with a two-year survival rate of 56%. This study demonstrates that local delivery of irinotecan into the brain parenchyma offers a safe route of administration over systemic delivery in the treatment of recurrent glioblastoma.

Simple Summary: We retrospectively evaluated the clinical outcomes of lung metastasectomy in 147 patients with pulmonary metastases from primary liver tumors at three medical centers. Multivariate analysis demonstrated that surgical resection as the initial primary liver tumor treatment and lower MELD-Na scores significantly correlated with better OS. These findings can guide thoracic surgeons in patient selection and predicting surgical outcomes. Oligopulmonary metastases from primary liver tumors are typically treated surgically. We evaluated the clinical outcomes after lung metastasectomy in patients with pulmonary metastases from primary liver tumors. We retrospectively enrolled 147 consecutive patients with lung metastases from liver cancer who had undergone pulmonary metastasectomies at three medical centers between February 2007 and December 2020. All patients were pathologically confirmed to have lung metastases from liver cancer. Among the 147 patients, 110, 17, and 20 initially underwent surgical resection, radiofrequency ablation, and transcatheter arterial embolization, respectively. The 5-year overall survival (OS) in the study cohort was 22%. Univariate analysis revealed four factors associated with better OS: surgical resection as the initial primary liver tumor treatment (p = 0.004), a disease-free interval exceeding 12 months after the initial liver surgery (p = 0.036), a lower Model for End-Stage Liver Disease (MELD)-Na score (≤20) for liver cirrhosis (p = 0.044), and the absence of local liver tumor recurrence at the time of pulmonary metastasectomy (p = 0.004). Multivariate analysis demonstrated that surgical resection as the initial primary liver tumor treatment and lower MELD-Na scores significantly correlated with better OS. Our findings can assist thoracic surgeons in selecting suitable patients for surgery and predicting surgical outcomes. [ABSTRACT FROM AUTHOR]

Simple Summary: Head and Neck Cancer is often diagnosed at an advanced stage, resulting in poor long-term prognosis. Additionally, this cancer is resistant to chemotherapy. This systematic review article aims to examine the literature on published methods to overcome resistance to chemotherapy for head and neck cancer. According to the "cancer stem cell" (CSCs) theory, tumors are a diverse and expanding group of malignant cells that originate from a small number of CSCs. Despite treatment, these cells can still become active and proliferate, which can result in distant metastasis and local recurrences. A new paradigm in cancer treatment involves targeting both CSCs and the cancer cells in a tumor. This review aims to examine the literature on methods published to overcome chemoresistance due to the presence of CSCs in head and neck cancers. The review was registered with PROSPERO (ID# CRD42024512809). After Pub Med, Scopus, and WoS database searches, 31 relevant articles on oral squamous cell carcinoma (OSCC) were selected. Compounds that increased chemosensitivity by targeting CSCs in head and neck squamous cell carcinoma (HNSCC) were divided into (1) natural products, (2) adjuvant molecules to traditional chemotherapy, and (3) CSCs targeting patient-specific fresh biopsies for functional precision medicine.

Simple Summary: Total thyroidectomy and dissection of cervical lymph node compartments, depending on serum calcitonin levels and ultrasound findings, is standard treatment for patients with medullary thyroid cancer. The aim of this study was to evaluate whether pre-operative calcitonin and CEA levels can be useful as biomarkers of the extent of lymph node metastases at diagnosis. Results indicate that pre-operative serum calcitonin and CEA levels can predict presence, number, and site of lymph node metastases and, more specifically, values of 90 pg/mL for calcitonin and 17 ng/mL for CEA accurately indicate the N1b status. Since surgery is the only curative treatment for medullary thyroid cancer and there is not a strong indication regarding the extent of lymphadenectomy, these findings may help in the choice of the extent of neck dissection. Background: In medullary thyroid cancer (MTC), lymph node metastases are often present at diagnosis and the extent of surgery is usually based upon pre-operative calcitonin and CEA levels as well as ultrasound findings. The aim of this study was to evaluate the role of pre-operative calcitonin and CEA levels as predictive markers of the burden of lymph node metastases at diagnosis. Methods: we conducted a retrospective study analyzing 87 MTC patients. Results: The median levels of calcitonin and CEA were 88.4 pg/mL and 7.0 ng/mL, respectively, in patients with no lymph nodes metastases; 108.0 pg/mL and 9.6 ng/mL, respectively, in patients with metastases to 1–5 lymph nodes; 520.5 pg/mL and 43.2 ng/mL, respectively, in patients with metastases to >5 lymph nodes. There were no significant differences in pre-operative calcitonin and CEA values between N0 and N1a patients, whereas they were significantly higher in N1b patients. Pre-operative cut-off levels distinguishing N0/N1a from N1b patients were 90 pg/mL for calcitonin (sensitivity 100%, specificity 59.3%, AUC = 0.82) and 17 ng/mL for CEA (sensitivity 100%, specificity 75%, AUC = 0.89). Conclusions: in patients with MTC, pre-operative serum calcitonin and CEA levels may drive the decision-making process to better define the extent of surgery. [ABSTRACT FROM AUTHOR]

Simple Summary: Lung carcinoids are known to be less malignant than other types of lung cancers. However, atypical lung carcinoids are more prone to recur after radical surgery than typical lung carcinoids. The aim of our retrospective study was to assess the rate of recurrence of low-stage atypical and typical carcinoids when accounting for competing events. We confirmed that atypical carcinoids recurred more often than typical carcinoids within 5 and 10 years after radical surgery. Atypical carcinoids at a low stage are more prone to recur after radical surgery, suggesting that all patients operated for atypical carcinoid should undergo close follow-up care after surgery. Atypical lung carcinoid (AC) is widely accepted to recur more often after radical resection than typical lung carcinoid (TC). However, their recurrence rates have never been compared in a multi-state competing risks model. We retrospectively reviewed files from patients with AC and TC who had been radically resected at our European Neuroendocrine Tumor Society Center of Excellence between 2009 and 2020. We estimated the recurrence rates between the AC and TC patients counting unrelated death as a competing event using Aalen–Johansen estimates and compared them using a multi-state Cox model. Finally, we analyzed all AC and TC recurrences as to resection type, pathological stage, resection margin, recurrence site, and time to recurrence. The study included 217 patients, of whom 194 had TC and 23 had AC. The median follow-up was 9.4 years. The AC patients experienced recurrence at a higher rate (hazard ratio [HR] 16.0, 95% confidence interval [CI] 5.3–47.9, p < 0.001). Correspondingly, the 5- and 10-year recurrence rates were 18% and 32% for AC and merely 1.0% and 2.4% for TC. In patients without nodal involvement, AC recurred at a considerably higher rate (HR 41.2, 95% CI 8.7–194.8, p < 0.001) than TC. In both AC and TC, most recurrences were distant and occurred in patients with a resection margin less than 2 cm. We conclude that AC recurs more often than TC, even in patients without nodal involvement at surgery, suggesting that all AC patients regardless of their pathological stage should undergo close follow-up care after surgery.

Simple Summary: Placental allograft tissue has been extensively used in wound healing. It can also be placed along the neurovascular bundles during radical prostatectomy to improve post-operative continence and erectile function recovery. The existing literature shows how placental allografts lead to improved functional recovery after radical prostatectomy. It is unknown whether these allografts have an impact on biochemical recurrence (BCR). Our study was a single surgeon retrospective review of 362 radical prostatectomy cases. The subgroups were the negative control group and two brands of cryopreserved amniotic membrane (CAM). Our data show improved continence recovery using CAM allografts. At a median follow-up of 41 months, there was no observed impact of BCR. Interestingly, in vitro analysis also revealed decreased cell viability of prostate cancer cell lines when incubated with the CAM allograft. Although further investigation is required, our data do not support a need for oncologic concern while using CAM allografts during radical prostatectomy. Background: Human placental allografts are widely used to promote wound healing. Placental (or amniotic membrane/umbilical cord) allografts are placed along the neurovascular bundles during radical prostatectomy to improve continence and erectile function recovery. It is unknown whether placental allografts impact biochemical recurrence (BCR). Methods: This was a single-surgeon retrospective study of 566 robotic radical prostatectomies performed from April 2015 to March 2021. The patients were divided into three groups: the negative control, Brand A, and Brand B. Brand A and Brand B were both cryopreserved amniotic membrane (CAM) allografts. A total of 324 cases were included for BCR Kaplan–Meier and risk-adjusted multivariate analyses (362 for continence analysis). In vitro analyses were performed to determine the effect of CAM allografts on prostate cancer (PCa) cell line growth. Results: For propensity score-matched analysis (adjusting for pre-operative PSA, tumor stage, Gleason Grade, and margin status), (1) the allograft groups did not show differences in time to BCR vs. the negative control group (p = 0.7), and (2) combined allograft treatment groups showed better continence recovery vs. the negative controls (p = 0.01). In vitro, placental allografts reduced PCa cell line growth in co-culture assays. Conclusions: cryopreserved AM allografts (combined or individual brands) did not show a significant effect on BCR but improved continence recovery for PCa patients. [ABSTRACT FROM AUTHOR]

Simple Summary: Patients with inflammatory bowel disease (IBD) face an increased risk of colorectal cancer, necessitating a surveillance program to detect early signs of cancer. Evaluating the effectiveness and safety of IBD medications in patients with a history of previous or active cancer, as well as assessing antineoplastic drugs in those with IBD, is crucial. This review outlines known risk factors, surveillance, and appropriate management strategies for patients with IBD and concomitant history of cancer. Patients with inflammatory bowel diseases (IBDs), including both ulcerative colitis (UC) and Crohn's disease (CD), are at a higher risk of developing colorectal cancer (CRC). However, advancements in endoscopic imaging techniques, integrated surveillance programs, and improved medical therapies have led to a decrease in the incidence of CRC among IBD patients. Currently, the management of patients with IBD who have a history of or ongoing active malignancy is an unmet need. This involves balancing the risk of cancer recurrence/progression with the potential exacerbation of IBD if the medications are discontinued. The objective of this review is to provide an updated summary of the epidemiology, causes, risk factors, and surveillance approaches for CRC in individuals with IBD, and to offer practical guidance on managing IBD patients with history of previous or active cancer.

Simple Summary: Breast reconstruction is considered for any patient who is undergoing surgical treatment for breast cancer. Many factors must be considered when discussing reconstruction, including patient risk factors, the type of material used for breast restoration, and the timing of surgery relative to other adjuvant treatments, such as radiotherapy. Plans for post-mastectomy radiotherapy significantly impact whether a breast reconstruction may be performed at the same time as a mastectomy (immediate reconstruction) or delayed for a later time (delayed reconstruction). The risk of surgical complications from irradiating a reconstructed breast is often weighed against the benefits of fewer surgeries and the potential for an improved quality of life when discussing eligibility for immediate reconstruction. This narrative review covers the current trends and controversies regarding breast reconstruction and radiotherapy. We aim to provide the context and relevant evidence for general community-practice oncologists and oncology providers who counsel patients on the sequencing and modalities of radiotherapy and breast reconstruction. Immediate breast reconstruction (IBR) following a mastectomy, combined with radiotherapy, presents a multifaceted approach to breast cancer treatment, balancing oncological safety and aesthetic outcomes. IBR, typically involving the use of implants or autologous tissue, aims to restore breast morphology directly after a mastectomy, minimizing the psychological and physical impacts. However, integrating radiotherapy with IBR is complex due to the potential adverse effects on reconstructed tissues. Radiotherapy, essential for reducing local recurrence, can induce fibrosis, capsular contracture, and compromised aesthetic results. This narrative review covers the current trends in the sequencing of breast reconstruction and radiotherapy. We discuss patient selection, timing of radiotherapy, and reconstructive techniques, with special attention paid to quality-of-life outcomes that are increasingly reported in clinical trials. Emerging evidence supports the feasibility of IBR with careful patient selection and tailored therapeutic approaches, although ongoing research is necessary to refine protocols and enhance outcomes. Overall, IBR in the context of radiotherapy remains a promising but intricate treatment modality, requiring a nuanced balance between cancer control and aesthetic restoration. [ABSTRACT FROM AUTHOR]

Simple Summary: Multiple myeloma is a heterogenous hematological condition with a worldwide incidence of between 0.5–5 per 100,000. The standard front-line treatment algorithm suggests induction chemotherapy, early stem cell transplant in those eligible, followed by maintenance chemotherapy. Unfortunately, most people subsequently relapse and require salvage treatment. A wide array of options are available in the management of relapse/refractory multiple myeloma. Our review aims to describe the new, approved treatment modalities in this setting while describing data on the efficacy, tolerability, and nuances of each available option. Multiple myeloma is a heterogeneous condition characterized by the proliferation of monoclonal B-cells, for which there is currently no curative treatment available. Relapses are, unfortunately, common after first-line treatment. While the prognosis for relapsed refractory multiple myeloma is generally poor, advances in the treatment of relapsed or refractory multiple myeloma offer hope. However, the expansion of effective options in targeted treatment offers renewed optimism and hope that patients who fail on older therapies may respond to newer modalities, which are often used in combination. We review currently approved and novel investigational agents classified by mechanisms of action, efficacy, approved setting, and adverse events. We delve into future directions of treatment for relapsed/refractory multiple myeloma, reviewing novel agents and therapeutic targets for the future. [ABSTRACT FROM AUTHOR]

Simple Summary: This research aims to identify preoperative factors that may predict positive resection margins in patients undergoing breast-conserving surgery for early-stage breast cancer. By retrospectively analyzing patient records from 2009 to 2017, the study investigates preoperative factors associated with positive resection margins. The findings indicate that neoadjuvant chemotherapy and the presence of ductal carcinoma in situ are significantly associated with positive resection margins. These results underscore the importance of these preoperative factors in surgical planning and management, potentially leading to improved outcomes for breast cancer patients. The primary objective of this study was to identify preoperative factors that could be associated with positive resection margins. We also tried to analyze the local recurrence and overall survival in patients who received conservative treatment for early-stage breast cancer and correlate these parameters with preoperative factors. A retrospective examination was conducted on the medical records and pathological reports of 143 patients who underwent breast-conserving surgery (BCS) for breast cancer in our department from 2009 to 2017. Postoperative outcomes were assessed through phone contact and statistical analyses, including GraphPad Prism, and Fisher's exact test, the Chi-square test, and the log-rank test were employed. The results revealed positive resection margins in 7.69% (11 cases) of the 143 patients, with an overall mortality rate of 16.66% for those with positive margins and 6.59% for those with negative margins. Statistical analysis indicated no significant differences in the overall (p = 0.5) or specific (p = 0.53) survival between the positive and negative margin groups. The positive margins were significantly associated with neoadjuvant chemotherapy (p < 0.0001) and the presence of ductal carcinoma in situ (DCIS) (p = 0.01). Among the analyzed factors, two out of sixteen were significantly linked to positive resection margins in BCS, emphasizing their importance in surgical management planning for early-stage breast cancer.

Simple Summary: Postoperative adjuvant chemotherapy generally improves survival in patients with breast cancer. However, adjuvant chemotherapy does not benefit all patients. There are considerations and guidelines that guide us as to whether or not chemotherapy is recommended to a particular patient. The decision is based on clinicopathologic features and may be aided by multigene assays. The Oncotype DX test is used worldwide. It makes the recommendation more accurate; however, there are possibilities to refine the process to make a more accurate decision. We investigated how we could move forward in recommending adjuvant chemotherapy. Background: The use of the Oncotype DX test reduces the rate of adjuvant chemotherapy recommendations. Few in-depth analyses have been performed on this decision-making process. Methods: We retrospectively analyzed patient data based on available Oncotype DX test results (RS) irrespective of nodal status at a single center. We collected recommendations from six oncologists, first without RS (pre-RS) and then with RS results (post-RS). We investigated changes in recommendations, agreement between oncologist decisions, and the effect of different National Comprehensive Cancer Network (NCCN) recommendation categories (for, against, and considering chemotherapy). Results: Data from 201 patients were included in the analysis. Recommendation of chemotherapy decreased by an average of 39.5%. Agreement improved substantially with RS, with a kappa value pre-RS of 0.37 (fair agreement) and post-RS of 0.75 (substantial agreement). Discordance remained substantial in cases where the NCCN recommendations considered chemotherapy only (32%). Pre-RS consensus against chemotherapy predicted low RS results (50 out of 51 patients). Post-RS consensus was highest in the NCCN chemotherapy recommendation group. Conclusions: The Oncotype DX test substantially improves decision accuracy in recommending adjuvant chemotherapy. It may be further improved with a consensus decision. In the case of pre-RS consensus against chemotherapy, the test can be spared. [ABSTRACT FROM AUTHOR]

Simple Summary: Older patients with locally advanced non-small cell lung cancer may not be candidates for standard treatment due to their poor performance status. Immunotherapy and radiotherapy are well tolerated and may become the treatment of choice for those patients. This hypothesis should be confirmed in future clinical trials. The standard of care for locally advanced non-small-cell lung cancer (NSCLC) is either surgery combined with chemotherapy pre- or postoperatively or concurrent chemotherapy and radiotherapy. However, older and frail patients may not be candidates for surgery and chemotherapy due to the high mortality risk and are frequently referred to radiotherapy alone, which is better tolerated but carries a high risk of disease recurrence. Recently, immunotherapy with immune checkpoint inhibitors (ICIs) may induce a high response rate among cancer patients with positive programmed death ligand 1 (PD-L1) expression. Immunotherapy is also well tolerated among older patients. Laboratory and clinical studies have reported synergy between radiotherapy and ICI. The combination of ICI and radiotherapy may improve local control and survival for NSCLC patients who are not candidates for surgery and chemotherapy or decline these two modalities. The International Geriatric Radiotherapy Group proposes a protocol combining radiotherapy and immunotherapy based on the presence or absence of PD-L1 to optimize the survival of those patients.

Simple Summary: Magnetic resonance imaging (MRI) plays a crucial role in rectal cancer management, offering valuable information for staging, treatment response, and patient prognosis. MRI biomarkers, such as circumferential resection margin (CRM), extramural venous invasion (EMVI), tumour deposits, and MRI tumour regression grade (mrTRG) alongside functional imaging techniques such as diffusion-weighted imaging (DWI) and dynamic contrast enhancement (DCE) are essential in clinical decision-making. Additionally, emerging technologies like radiomics and artificial intelligence (AI) are showing promise in improving the precision of rectal cancer care. As the focus increasingly shifts toward non-invasive management, such as 'watch-and-wait' approach, this review discusses the role of predictive and prognostic MRI biomarkers in rectal cancer and how they integrate into everyday clinical practice. The role of magnetic resonance imaging (MRI) in rectal cancer management has significantly increased over the last decade, in line with more personalized treatment approaches. Total neoadjuvant treatment (TNT) plays a pivotal role in the shift from traditional surgical approach to non-surgical approaches such as 'watch-and-wait'. MRI plays a central role in this evolving landscape, providing essential morphological and functional data that support clinical decision-making. Key MRI-based biomarkers, including circumferential resection margin (CRM), extramural venous invasion (EMVI), tumour deposits, diffusion-weighted imaging (DWI), and MRI tumour regression grade (mrTRG), have proven valuable for staging, response assessment, and patient prognosis. Functional imaging techniques, such as dynamic contrast-enhanced MRI (DCE-MRI), alongside emerging biomarkers derived from radiomics and artificial intelligence (AI) have the potential to transform rectal cancer management offering data that enhance T and N staging, histopathological characterization, prediction of treatment response, recurrence detection, and identification of genomic features. This review outlines validated morphological and functional MRI-derived biomarkers with both prognostic and predictive significance, while also exploring the potential of radiomics and artificial intelligence in rectal cancer management. Furthermore, we discuss the role of rectal MRI in the 'watch-and-wait' approach, highlighting important practical aspects in selecting patients for non-surgical management. [ABSTRACT FROM AUTHOR]

Simple Summary: This study introduces a deep learning model designed to predict the 5-year recurrence risk of lung adenocarcinoma based on histopathology images. Using a dataset of 189 patients with 455 histopathology slides, our model demonstrated superior performance in risk stratification, achieving a hazard ratio of 2.29 (95% CI: 1.69–3.09, p < 0.005). This outperforms several existing deep learning methods, showcasing the potential of deep learning in automatically predicting lung adenocarcinoma recurrence risk. The superior performance of this model underscores the potential for deep learning models to be integrated into clinical workflows for more accurate and automated risk assessment in lung adenocarcinoma. This could lead to more personalized treatment strategies and better patient outcomes. Lung cancer is the leading cause of cancer-related death in the United States. Lung adenocarcinoma (LUAD) is one of the most common subtypes of lung cancer that can be treated with resection. While resection can be curative, there is a significant risk of recurrence, which necessitates close monitoring and additional treatment planning. Traditionally, microscopic evaluation of tumor grading in resected specimens is a standard pathologic practice that informs subsequent therapy and patient management. However, this approach is labor-intensive and subject to inter-observer variability. To address the challenge of accurately predicting recurrence, we propose a deep learning-based model to predict the 5-year recurrence of LUAD in patients following surgical resection. In our model, we introduce an innovative dual-attention architecture that significantly enhances computational efficiency. Our model demonstrates excellent performance in recurrent risk stratification, achieving a hazard ratio of 2.29 (95% CI: 1.69–3.09, p < 0.005), which outperforms several existing deep learning methods. This study contributes to ongoing efforts to use deep learning models for automatically learning histologic patterns from whole slide images (WSIs) and predicting LUAD recurrence risk, thereby improving the accuracy and efficiency of treatment decision making.

Simple Summary: The use of radioactive iodine (RAI) for the treatment of patients with thyroid cancer at intermediate risk of recurrence is controversial. Evidence to date has not conclusively proven that there are benefits of this strategy to survival or recurrence after surgery for thyroid cancer. We describe key elements that can help clinicians decide when to prescribe RAI to this group of patients. These include a thorough discussion of the purpose of RAI therapy, better prediction of recurrence risk, the use of tumor markers after surgery, the use of the genetic profile of the tumor when available, and a detailed evaluation of the adverse effects of RAI, patient medical problems, and patient preferences. Integration of these variables will ensure a more comprehensive assessment of the risks and benefits of RAI treatment with the ultimate goal of avoiding overtreatment and reducing harm. The use of radioactive iodine (RAI) after total thyroidectomy for patients at the American Thyroid Association (ATA) who are at intermediate risk of recurrence is controversial. This is due to the lack of prospective randomized trials proving a benefit to recurrence or survival of RAI therapy in this group. In the absence of such evidence, clinicians struggle to recommend for or against this therapeutic approach which frequently results in overtreatment. This review describes key elements in the decision-making process that help clinicians more comprehensively evaluate the need for RAI therapy in patients with thyroid cancer at intermediate risk of recurrence. A clear definition of the purpose of RAI therapy should be conveyed to patients. In this sense, adjuvant RAI therapy intends to decrease recurrence, and ablation therapy is used to facilitate surveillance. Better stratification of the intermediate risk category into a low–intermediate subgroup and an intermediate–high-risk subgroup results in less heterogeneity and a more precise prediction of recurrence risk. The evaluation of post-operative thyroglobulin levels may prevent the overtreatment of low–intermediate-risk patients when their thyroglobulin level is <2.5 ng/mL. the integration of tumor genomics (when available) alongside pathologic features can enhance the ability of the clinician to predict iodine concentration in thyroid cancer cells. Finally, a detailed consideration of the adverse effects of RAI, patients' comorbidities, and patient preferences will result in a patient-centered personalized approach. Systematic examination of these variables will ultimately provide a framework for making more educated decisions on the use of RAI in patients at intermediate risk of recurrence that will prevent overtreatment and minimize harm.

Simple Summary: Squamous cell carcinoma of the anus or anal cancer is increasing in prevalence, and the standard treatment of mitomycin and 5-fluorouracil is too toxic for many patients. Unfortunately, there is currently no standard of care for what to do for this disease when someone is not a candidate for this aggressive treatment. Here, we demonstrate the promising preliminary toxicity profile and efficacy of the combination of weekly carboplatin and paclitaxel chemotherapy for patients with localized anal cancer. This regimen was able to complete 80% of the intended treatments with anticipated toxicities, and 89% achieved a complete clinical response. This combination is a promising regimen and is already being investigated further in a clinical trial. Background: Although squamous cell carcinoma of the anus (SCCA) is a relatively uncommon malignancy in the United States, it continues to increase in incidence. Treatment for locoregional disease includes mitomycin and 5-fluorouracil with radiation. This combination is associated with significant toxicity, limiting its use in patients who are older or have certain comorbidities. Carboplatin and paclitaxel (C/P) is an accepted treatment regimen for metastatic SCCA. We aim to evaluate the efficacy and toxicity of weekly C/P given with radiation for patients unable to receive standard chemoradiation for SCCA. Methods: From our cancer registry, adult patients who received weekly intravenous C/P concurrent with standard-dose radiation for localized SCCA were included in this study. Clinical response was determined based on the evidence of disease on imaging and/or anoscopy. Toxicities were graded according to the CTCAE v5. Results: Ten patients were included; eight were female, and the median age was 75.5 years (54–87). Six had T2 disease, and four had T3 tumors. Four had node-positive disease. The majority (70%) of patients were dosed at standard C (AUC 2) and P (50 mg/m2), with a limited subset requiring dose reduction for baseline performance status. Patients completed a mean of 78.3% (40–100%) of the intended treatments. A total of 89% of the patients achieved a complete clinical response. With a median follow-up of 25.8 months (3.4–50.4 months), 67% of the patients are alive and without recurrence. Two patients have had local recurrence, and one patient had metastatic progression. The most common toxicities of any grade included leukopenia (100%), anemia (100%), radiation dermatitis (100%), diarrhea (100%), and fatigue (100%). Grade 3 or higher toxicities included neutropenic fever (20%), neutropenia (30%), and anemia (30%). Conclusions: This study demonstrates promising tolerability and efficacy for weekly C/P chemoradiation for patients with anal cancer unable to receive mitomycin and 5-fluorouracil. This regimen merits further investigation in prospective clinical trials. [ABSTRACT FROM AUTHOR]

Myxoid liposarcomas are malignant soft-tissue sarcomas whose treatment represents a challenge, even for the most experienced surgeon. In this study, we report on our experience with the treatment of myxoid liposarcomas of the thigh. Our retrospective analysis included myxoid liposarcomas of the thigh treated with surgical resection between 2016 and 2022. Resection margins, complications, local recurrences, and metastases were recorded. The oncological outcome of each case was evaluated at their latest follow-up. Adjuvant therapies were administered according to the ESMO guidelines. Functionality was assessed with the MSTS score before surgery and at the patients' latest follow-up. Thirty cases (ten high-grade and 20 low-grade) were included. The mean diameter was 11.8 cm. Twenty-four cases had wide margins (80%) and six (20%) were marginal. Five cases (60% marginal) had local recurrences (17%). Marginal resection was associated with a higher risk of local recurrence (p = 0.041). Three cases with high-grade tumors (10%) developed metastases. At the patients' latest follow-up, their mean MSTS score had risen from 22.9 to 27.3. While tumor grade influences the risk of metastases, the quality of resection margins can determine the local recurrence rate. An adequate surgery can lead to good post-operative functional outcomes.

Background/Objectives: The most important prognostic factors in curatively treated prostate cancer are T and N stage, histology, grade group and initial PSA. A recent study found that men with blood calcium levels at the high end of the normal range are over two-and-a-half times more likely to develop fatal prostate cancer than those with lower calcium levels. However, there is limited evidence regarding the prognostic value of calcium levels at the time of prostate cancer diagnosis. We aimed to determine whether a calcium level in the upper range of normal values has any prognostic value in curatively treated prostate cancer. Methods: We conducted a retrospective analysis of 84 consecutive patients with prostate cancer who underwent curative-intent radiotherapy—either as primary treatment or adjuvant therapy—using external beam radiotherapy with or without brachytherapy. We analyzed all pertinent prognostic factors that could potentially impact disease-free survival. Results: The study revealed that calcium levels at diagnosis significantly predict disease-free survival, whereas the initial PSA level did not hold prognostic significance—likely due to interference from benign prostatic hyperplasia. Conclusions: If our findings are validated, calcium levels at the time of prostate cancer diagnosis could be incorporated into future predictive and prognostic models. [ABSTRACT FROM AUTHOR]

Simple Summary: Lung cancer continues to be the leading cause of cancer-related deaths worldwide. Many patients present advanced disease at the time of the diagnosis. Neoadjuvant therapy aims to reduce the tumor stage and improve the operability of patients, and simultaneously leads to tumor regression. The tumor regression grade reflects the degree of pathological response to therapy. Thus, we conducted this study to identify the predictors for pathologic response after neoadjuvant treatment followed by surgery. The second goal of our research was to find the relationship between survival and tumor regression. Our study revealed that the histology of the primary tumor, lymph node size in the preoperative CT scan (>1.7 cm), and absolute tumor size reduction after neoadjuvant treatment (>2.6 cm) independently predict the effectiveness of tumor regression. Age > 70 years, extended resection > one lobe, and tumor recurrence or metastasis were identified as significant independent predictors of reduced overall survival. Our study aimed to identify predictors for the effectiveness of tumor regression in lung cancer patients undergoing neoadjuvant treatment and cancer resections. Patients admitted between 2016 and 2022 were included in the study. Based on the histology of the tumor, patients were categorized into a lung adenocarcinoma group (LUAD) and squamous cell carcinoma group (SQCA). Ninety-five patients with non-small-cell lung cancer were included in the study. A total of 58 (61.1%) and 37 (38.9%) patients were included in the LUAD and SQCA groups, respectively. Additionally, 9 (9.5%), 56 (58.9%), and 30 (31.6%) patients were categorized with a tumor regression score of I, II, and III, respectively. In multivariable analyses, histology of the primary tumor (SQCA), lymph node size in the preoperative CT scan (>1.7 cm), and absolute tumor size reduction after neoadjuvant treatment (>2.6 cm) independently predict effectiveness of tumor regression (OR [95% confidence interval, p-value] of 6.88 [2.40–19.77, p < 0.0001], 3.13 [1.11–8.83, p = 0.0310], and 3.76 [1.20–11.81, p = 0.0233], respectively). Age > 70 years, extended resection > one lobe, and tumor recurrence or metastasis were identified as significant independent predictors of reduced overall survival. Assessment of tumor size before and after neoadjuvant treatment might help to identify high-risk patients with decreased survival and to improve patient management and care. [ABSTRACT FROM AUTHOR]

Simple Summary: Patients undergoing definitive prostate cancer therapy experience recurrence despite standard-of-care interventions. Biochemical recurrence is detected initially via prostate-specific antigen (PSA) monitoring and is defined as biochemical recurrence. The clinical importance of the early detection of biochemical recurrence is underscored in this study. This review seeks to further elucidate modalities used for earlier identification of biochemical recurrence. Specifically, we highlight in this review the clinical utility of both tissue biomarkers and prostate-specific membrane antigen-positron emission tomography (PSMA PET) in monitoring patients for recurrence. The summarization provided in this article can help guide clinicians in understanding the recent developments in this field. Despite curative-intent local therapy, approximately 27% to 53% of prostate cancer (PCa) patients experience prostate-specific antigen (PSA) recurrence, known as biochemical recurrence (BCR). BCR significantly raises the risk of PCa-related morbidity and mortality, yet there is no consensus on optimal management. Prostate-specific membrane antigen-positron emission tomography (PSMA PET) has emerged as highly sensitive imaging, distinguishing local recurrences from distant metastases, crucially influencing treatment decisions. Genomic biomarkers such as Decipher, Prolaris, and Oncotype DX contribute to refining recurrence risk profiles, guiding decisions on intensifying adjuvant therapies, like radiotherapy and androgen deprivation therapy (ADT). This review assesses PSMA PET and biomarker utility in post-radical prostatectomy BCR scenarios, highlighting their impact on clinical decision-making. Despite their promising roles, the routine integration of biomarkers is limited by availability and cost, requiring further evidence. PSMA PET remains indispensable for restaging and treatment evaluation in these patients. Integrating biomarkers and PSMA PET promises to optimize personalized management strategies for BCR, though more comprehensive consensus-building studies are needed to define their standardized utility in clinical practice.

Simple Summary: This study identified the risk factors of non-local recurrence of isocitrate dehydrogenase (IDH) wild-type glioblastoma, a highly aggressive brain tumor. We found that subventricular zone involvement significantly increased the risk of non-local recurrence, with the tumor contacting the trigone of the lateral ventricle and tending to develop subependymal dissemination. A meta-analysis of previous studies confirmed subventricular zone involvement and O-6-methylguanine DNA methyltransferase promoter methylation as risk factors for non-local recurrence. In contrast, ventricular opening via surgery did not increase the risk of non-local recurrence. These findings emphasize the need for tailored therapeutic strategies based on tumor location and molecular characteristics and provide valuable guidance for clinical decision-making in managing recurrent glioblastoma. Isocitrate dehydrogenase (IDH) wild-type glioblastoma (GBM) is a highly aggressive brain tumor with a high recurrence rate despite adjuvant treatment. This study aimed to evaluate the risk factors for non-local recurrence of GBM. In the present study, we analyzed 104 GBMs with a single lesion (non-multifocal or multicentric). Univariate analysis revealed that subventricular zone (SVZ) involvement was significantly associated with non-local recurrence (hazard ratio [HR]: 2.09 [1.08–4.05]). Tumors in contact with the trigone of the lateral ventricle tended to develop subependymal dissemination (p = 0.008). Ventricular opening via surgery did not increase the risk of non-local recurrence in patients with SVZ involvement (p = 0.190). A systematic review was performed to investigate the risk of non-local recurrence, and 21 studies were identified. A meta-analysis of previous studies confirmed SVZ involvement (odds ratio [OR]: 1.30 [1.01–1.67]) and O-6-methylguanine DNA methyltransferase promoter methylation (OR: 1.55 [1.09–2.20]) as significant risk factors for local recurrence. A time-dependent meta-analysis revealed a significant association between SVZ involvement and dissemination (HR: 1.69 [1.09–2.63]), while no significant association was found for distant recurrence (HR: 1.29 [0.74–2.27]). Understanding SVZ involvement and specific tumor locations associated with non-local recurrence provides critical insights for the management of GBM. [ABSTRACT FROM AUTHOR]

Simple Summary: The combination of chemoradiotherapy followed by surgery (trimodality therapy) is considered standard of care for patients with locally advanced esophageal adenocarcinoma, but many potential candidates for surgery receive curative-intent chemoradiotherapy alone. This study compared the outcomes of patients who received trimodality therapy to those who received curative-intent chemoradiotherapy. Our primary analysis found that trimodality therapy reduced the risk of local tumor recurrences, but we did not detect statistically significant differences in the risks of distant metastases or mortality. These results can help patients and clinicians make informed treatment decisions, although further studies are needed to refine our understanding of the trade-offs between the two treatment strategies. The optimal management of patients with locally advanced esophageal adenocarcinoma is unclear. Neoadjuvant chemoradiotherapy followed by esophagectomy (trimodality therapy) is supported as a standard of care, but definitive chemoradiotherapy is frequently given in practice to patients who may have been surgical candidates. This multi-institutional retrospective cohort study compared the outcomes of consecutive patients diagnosed with stage II to IVA esophageal adenocarcinoma between 2004 and 2018 who planned to undergo trimodality therapy or definitive chemoradiotherapy. A total of 493 patients were included, of whom 435 intended to undergo trimodality therapy and 56 intended to undergo definitive chemoradiotherapy. After a median follow-up of 7.3 years, trimodality therapy was associated with a lower risk of locoregional failure (5-year risk, 30.5% vs. 61.3%; HR, 0.39; 95% CI, 0.24–0.62; p < 0.001 ) but not distant metastases (5-year risk, 58.2% vs. 53.9%; HR, 1.21; 95% CI, 0.77–1.91; p = 0.40 ). There were no differences in overall survival (HR, 0.78; 95% CI, 0.56–1.09; p = 0.14 ) or cancer-specific survival (HR, 0.83; 95% CI, 0.57–1.21; p = 0.33 ). Findings were consistent on propensity score-matched sensitivity analyses. In conclusion, trimodality therapy was associated with a lower risk of locoregional failure, but this did not translate into a significantly lower risk of distant failure or improved survival. Further studies are required to accurately estimate the trade-offs between the two treatment strategies. [ABSTRACT FROM AUTHOR]

Simple Summary: Advanced prostate cancer (PCa) is a prominent contributor to cancer-related fatalities and is associated with significant morbidity and mortality. Currently, addressing the local recurrence of the disease after radiation therapy (RT) poses a significant clinical challenge. We established the first syngeneic model of radiorecurrent PCa to evaluate the effectiveness of immune checkpoint inhibitors (ICIs) in combination with high-dose ionizing radiation (IR). We observed an enhanced anti-tumor response, which led to a delay in tumor growth and, in some cases, a complete elimination of tumors when combining IR with anti-CTLA4. This improvement was linked to an enhanced activation of total T cells, CD4+ helper T cells, and CD8+ cytotoxic T cells in both the draining lymph node and tumor. These results hold substantial potential for translation into clinical practice, serving as a proof of concept for the application of brachytherapy and immune checkpoint inhibitors (ICIs) in cases of recurrent disease. High-risk prostate cancer (PCa) is a leading cause in cancer death and can elicit significant morbidity and mortality. Currently, the salvage of local disease recurrence after radiation therapy (RT) is a major clinical problem. Immune checkpoint inhibitors (ICIs), which enhance immune activation, have demonstrated clinical therapeutic promise in combination with ionizing radiation (IR) in certain advanced cancers. We generated the TRAMP-C2 HF radiorecurrent syngeneic mouse model to evaluate the therapeutic efficacy of ICIs in combination with RT. The administration of anti-PDL1 and/or anti-CTLA4 did not achieve a significant tumor growth delay compared to the control. The combination of IR and anti-PDL1 did not yield additional a growth delay compared to IR and the isotype control. Strikingly, a significant tumor growth delay and complete cure in one-third of the mice were seen with the combination of IR and anti-CTLA4. Immune cells in tumor-draining lymph nodes and tumor-infiltrating lymphocytes from mice treated with IR and anti-CTLA4 demonstrated an upregulation of genes in T-cell functions and enrichment in both CD4+ and CD8+ T-cell populations compared to mice given IR and the isotype control. Taken together, these results indicate enhancement of T-cell response in radiorecurrent PCa by IR and anti-CTLA4. [ABSTRACT FROM AUTHOR]

Simple Summary: Three-dimensional (3D) telomere analysis using TeloView v 2.2 has shown promise in quantifying genomic instability and predicting therapy response. In a study of 156 Classic Hodgkin's lymphoma (cHL), we identified significant 3D telomere parameters that predict patient outcomes. A predictive model using four 3D telomere parameters, including the proportion of t-stumps (very short telomeres), achieved an area under curve (AUC) of 0.83, with a sensitivity and specificity of 0.82 and 0.78, respectively. Classic Hodgkin's lymphoma (cHL) is a curable cancer with a disease-free survival rate of over 10 years. Over 80% of diagnosed patients respond favorably to first-line chemotherapy, but few biomarkers exist that can predict the 15–20% of patients who experience refractory or early relapsed disease. To date, the identification of patients who will not respond to first-line therapy based on disease staging and traditional clinical risk factor analysis is still not possible. Three-dimensional (3D) telomere analysis using the TeloView® software platform has been shown to be a reliable tool to quantify genomic instability and to inform on disease progression and patients' response to therapy in several cancers. It also demonstrated telomere dysfunction in cHL elucidating biological mechanisms related to disease progression. Here, we report 3D telomere analysis on a multicenter cohort of 156 cHL patients. We used the cohort data as a training data set and identified significant 3D telomere parameters suitable to predict individual patient outcomes at the point of diagnosis. Multivariate analysis using logistic regression procedures allowed for developing a predictive scoring model using four 3D telomere parameters as predictors, including the proportion of t-stumps (very short telomeres), which has been a prominent predictor for cHL patient outcome in a previously published study using TeloView® analysis. The percentage of t-stumps was by far the most prominent predictor to identify refractory/relapsing (RR) cHL prior to initiation of adriamycin, bleomycin, vinblastine, and dacarbazine (ABVD) therapy. The model characteristics include an AUC of 0.83 in ROC analysis and a sensitivity and specificity of 0.82 and 0.78 respectively. [ABSTRACT FROM AUTHOR]

Simple Summary: Advances in the treatment of acute lymphoblastic leukemia (ALL) have led to a marked improvement in the survival rate of patients. Nevertheless, these patients may develop adverse effects during and after treatment, such as bone abnormalities and vitamin D deficiency. Bone remodeling allows for bone volume and structure to be maintained, which is controlled by the receptor activator of the nuclear factor-kB (RANK)/RANK ligand (RANKL)/osteoprotegerin (OPG) system-determining pathway in the balance between bone formation and resorption. Some reports have explored the role of corticosteroids in modulating the RANKL and OPG levels and RANKL/OPG ratio in pediatric patients. Nevertheless, studies evaluating the role of RANKL and OPG in the bone health of pediatric ALL patients during treatment are limited. During remission, we observed an increase in the RANKL/OPG ratio, increased RANKL levels, and decreased OPG levels in ALL patients. These changes may predispose such patients to the development of bone health disorders in their adult lives. Background: The receptor activator of the nuclear factor-kB (RANK)/RANK ligand (RANKL)/osteoprotegerin (OPG) pathway is a determining pathway in the balance between bone formation and resorption, and disruptions in this complex can affect bone metabolism. Methods: This study analyzes the changes in RANKL, OPG, and 25(OH)D levels; the RANKL/OPG ratio; and other bone turnover markers (BTMs) from diagnosis to complete remission in children with acute lymphoblastic leukemia (ALL). This is a prospective observational cohort study, carried out at the Instituto Mexicano del Seguro Social, Mexico City, including 33 patients (4–17 years) with newly diagnosed B-cell ALL. The patients were treated with the HP09 chemotherapy protocol. Children who had previously been treated with corticosteroids were excluded. A peripheral blood sample at diagnosis and remission was collected to determine the 25(OH)D and BTM concentrations. Results: Increased RANKL (p = 0.001) and osteocalcin (p < 0.001) levels and RANKL/OPG ratio (<0.001) and a decreased OPG level (p = 0.005) were observed at remission, predominantly in the high-risk (HR) relapse and vitamin D deficiency groups. A negative association between RANKL and OPG (r = −0.454, p = 0.008) was observed. Conclusions: we suggest that the RANKL/OPG ratio could serve as a bone remodeling marker in ALL patients.

Simple Summary: Ischemia-reperfusion injury (IRI) is the source of significant graft inflammation in liver transplantation. Such injuries can lead to increased recurrence of both benign and malignant diseases of the biliary tree after transplant. Herein, we review the mechanisms and risk factors for the link between IRI and biliary recurrence, as well as evidence for strategies to mitigate this damage. Liver transplantation is known to generate significant inflammation in the entire organ based on the metabolic profile and the tissue's ability to recover from the ischemia-reperfusion injury (IRI). This cascade contributes to post-transplant complications, affecting both the synthetic liver function (immediate) and the scar development in the biliary tree. The new occurrence of biliary strictures, and the recurrence of malignant and benign liver diseases, such as cholangiocarcinoma (CCA) and primary sclerosing cholangitis (PSC), are direct consequences linked to this inflammation. The accumulation of toxic metabolites, such as succinate, causes undirected electron flows, triggering the releases of reactive oxygen species (ROS) from a severely dysfunctional mitochondrial complex 1. This initiates the inflammatory IRI cascade, with subsequent ischemic biliary stricturing, and the upregulation of pro-tumorigenic signaling. Such inflammation is both local and systemic, promoting an immunocompromised status that can lead to the recurrence of underlying liver disease, both malignant and benign in nature. The traditional treatment for CCA was resection, when possible, followed by cytotoxic chemotherapy. Liver transplant oncology is increasingly recognized as a potentially curative approach for patients with intrahepatic (iCCA) and perihilar (pCCA) cholangiocarcinoma. The link between IRI and disease recurrence is increasingly recognized in transplant oncology for hepatocellular carcinoma. However, smaller numbers have prevented similar analyses for CCA. The mechanistic link may be even more critical in this disease, as IRI causes the most profound damage to the intrahepatic bile ducts. This article reviews the underlying mechanisms associated with biliary inflammation and biliary pathology after liver transplantation. One main focus is on the link between transplant-related IRI-associated inflammation and the recurrence of cholangiocarcinoma and benign liver diseases of the biliary tree. Risk factors and protective strategies are highlighted. [ABSTRACT FROM AUTHOR]

Simple Summary: The current investigation identifies differentially expressed genes that specifically influence the serous subtype of ovarian cancer. This subtype accounts for around three-quarters of ovarian cancer cases. To identify these genes, transcriptomic profiles of serous ovarian cancer and non-cancerous tissue samples were extracted from the Gene Expression Omnibus. Differentially expressed genes were derived using GEO2R tool analyses; genes consistently found among upregulated genes in these profiles were considered to be a serous gene set. Next, the serous gene set was examined for its ontological function using the Molecular Signatures Database and its mutational impact on the gene expression profile of high-grade serous ovarian (HGSO) adenocarcinoma. Results showed that 26 genes are amplified in over 5% of HGSO cancer patients, and many of these amplified genes are related to the cell cycle. These cell cycle-related genes were also identified as being involved in the recurrence of serous ovarian cancer. Overall, this study identifies genes that are potential prognostic markers for serous ovarian cancer. The objective of this study was to identify differentially expressed genes and their potential influence on the carcinogenesis of serous-type ovarian cancer tumors. Serous cancer is an epithelial ovarian cancer subtype and is the most common type of ovarian cancer. Transcriptomic profiles of serous cancer and non-cancerous datasets were obtained from the Gene Expression Omnibus (GEO-NCBI). Differentially expressed genes were then derived from those profiles; the identified genes were consistently upregulated in three or more transcriptomic profiles. These genes were considered as the serous ovarian cancer gene set for further study. The serous gene set derived from the transcriptomic profiles was then evaluated for ontological functional analysis using the Molecular Signatures Database. Next, we examined the mutational impact of this serous gene set on the transcriptomic profile of high-grade serous ovarian (HGSO) adenocarcinoma using the cBioPortal database. Results from OncoPrint revealed that 26 genes were amplified in more than 5% of HGSO cancer patients. Interestingly, several of these genes are involved in cell cycle processes, including genes ATPase family AAA domain containing 2 (ATAD2), recQ-like helicase 4 (RECQL4), cyclin E1 (CCNE1), anti-silencing function 1B histone chaperone (ASF1B), ribonuclease H2 subunit A (RNASEH2A), structural maintenance of chromosome 4 (SMC4), cell division cycle associated 20 (CDC20), and cell division cycle associated 8 (CDCA8). The receiver operating characteristic (ROC) curve results also revealed higher specificity and sensitivity for this subtype of tumors. Furthermore, these genes may affect the recurrence of serous ovarian carcinogenesis. Overall, our analytical study identifies cell cycle-related genes that can potentially be targeted as diagnostic and prognostic markers for serous ovarian cancer. [ABSTRACT FROM AUTHOR]

Simple Summary: This study explores the use of intraoperative magnetic resonance imaging (iMRI) in the surgical resection of brain metastases (BMs). The research aims to determine how iMRI can improve the precision of tumor removal, thereby enhancing patient outcomes. By providing real-time, high-resolution images during surgery, iMRI assists surgeons in achieving more complete tumor resection, potentially reducing recurrence rates and improving survival chances. Integrating iMRI into surgical protocols helps preserve neurological functions, especially for patients with BM in critical brain areas. This study highlights the safety and effectiveness of iMRI in neurosurgery and suggests its broader adoption for the better management of BMs. Intraoperative magnetic resonance imaging (iMRI) has witnessed significant growth in the field of neurosurgery, particularly in glioma surgery, enhancing image-guided neuronavigation and optimizing the extent of resection (EOR). Despite its extensive use in the treatment of gliomas, its utility in brain metastases (BMs) remains unexplored. This study examined the effect of iMRI on BM resection. This retrospective study was conducted at the neurosurgical center of the University Hospital of the Technical University of Munich and involved 25 patients with BM who underwent resection using 3-Tesla iMRI between 2018 and 2022. Volumetric measurements of the resected contrast-enhancing metastases were performed using preoperative, intraoperative, and postoperative MRI images. The Karnofsky Performance Score (KPS) and neurological status of the patients were assessed pre- and postoperatively. Local recurrence and in-brain progression were reported in patients who underwent follow-up MRI at 3 and 6 months postoperatively. In this cohort (n = 25, mean age 63.6 years), non-small-cell lung cancer (NSCLC) was the most common origin (28%). The mean surgical duration was 219.9 min, and that of iMRI was 61.7 min. Indications for iMRI were primarily associated with preoperative imaging, suggesting an unclear entity that is often suspicious for glioma. Gross total resection (GTR) was achieved in 21 patients (84%). Continued resection was pursued after iMRI in six cases (24%), resulting in an improved EOR of 100% in five cases and 97.6% in one case. Neurological status postoperatively remained stable in 60%, improved in 24%, and worsened in 16% of patients. No wound healing or postoperative complications were observed. Among the thirteen patients who underwent follow-up MRI 3 months postoperatively, one patient showed local recurrence at the site of resection, and seven patients showed in-brain progression. Of the eight patients who underwent a 6-month follow-up MRI, two showed local recurrence, while three exhibited in-brain progression. The observed favorable profiles of GTR, coupled with the notable absence of wound-healing problems and acute postoperative complications, affirm the safety and feasibility of incorporating iMRI into the neurosurgical workflow for resecting BM with specific indications. The real-time imaging capabilities of iMRI offer unparalleled precision, aiding meticulous tumor delineation and informed decision-making, ultimately contributing to improved patient outcomes. Although our experience suggests the potential benefits of iMRI as a safe tool for enhancing EOR, we acknowledge the need for larger prospective clinical trials. Comprehensive investigations on a broader scale are imperative to further elucidate the specific indications for iMRI in the context of BMs and to study its impact on survival. Rigorous prospective studies will refine our understanding of the clinical scenarios in which iMRI can maximize its impact, guiding neurosurgeons toward more informed and tailored decision-making.

Background and Objectives: The objective of this study was to present a rare case of non-keratinizing squamous cell carcinoma (SCC) of the lacrimal sac (LS). Neoplasms of the lacrimal drainage system are extremely rare. These lesions are predominantly malignant and are associated with a high mortality rate. Case Presentation: A 51-year-old woman was referred to an ophthalmologist with a history of unilateral epiphora, presbyopia, and abnormal eye discharge. Antibiotic therapy was applied and modified later due to persisting symptoms. After five months, edema of the medial left eye angle occurred. A lacrimal sac incision was performed, and a subsequent magnetic resonance imaging (MRI) scan revealed a 2 cm, contrast-enhanced solid tumor. The patient was qualified for dacryocystectomy, which was conducted by the otolaryngology department. Postoperative histopathologic findings indicated the presence of non-keratinizing SCC. During a reoperation, margins were extended, and the surgery was found to be radical. Following the reoperation, no alarming symptoms were observed. However, a follow-up MRI and positron emission tomography (PET) scan six weeks later revealed metastases. Further treatment is being planned. Conclusions: LS tumors are life-threatening conditions that are challenging to diagnose at an early stage. Surgical excision is the preferred treatment option. Imaging studies play an important role in post-operative follow-up because of the possibility of recurrence and metastasis, even after radical surgery. [ABSTRACT FROM AUTHOR]

Background: Autologous fat grafting (AFG) has emerged as a useful technique in breast reconstruction. Utilizing a patient's own fat from areas like the abdomen or thighs, AFG serves various reconstruction needs. Nevertheless, the oncological safety of AFG in breast cancer patients has become a contentious issue. Concerns about its influence on cancer recurrence and detention have led to significant clinical debate and the need for thorough investigation. Methods: To determine the impact of autologous fat grafting (AFG) on loco-regional recurrence (LRR) in breast cancer survivors undergoing reconstruction, a comprehensive search of databases including PubMed, Medline, Web of Science, and Cochrane libraries was conducted from November 2023 through March 2024. This search adhered to the PRISMA guidelines and aimed to identify all the relevant studies on AFG in the context of breast reconstruction post cancer treatment. A meta-analysis was performed. Results: Out of the studies reviewed, 40 met the inclusion criteria, with a total patient cohort of 14,078. The analysis revealed that AFG had no significant association with increased rates of LRR. Conclusions: According to the available literature, AFG is a safe reconstructive option for breast cancer patients and does not increase the risk of loco-regional recurrence. Nevertheless, further well-structured long-term prospective studies are required, since heterogeneity of available studies is high and requires standardization. [ABSTRACT FROM AUTHOR]

Metal-containing compounds are an important class of chemotherapeutics used to treat various manifestations of cancer. Despite the widespread clinical use and success of metallopharmaceuticals, they are ineffective towards a sub-population of tumours called cancer stem cells (CSCs). CSCs evade current chemotherapeutic regimens (including metallopharmaceuticals) and promote cancer relapse and metastasis. Here, we report the synthesis, characterisation and anti-breast CSCs properties of a series of cobalt(III)-polypyridyl complexes with salicylic acid. The lead cobalt(III) complex 6 (containing 3,4,7,8-tetramethyl-1,10-phenanthroline) displayed low micromolar potency towards breast CSCs, significantly lower than the gold-standard anti-breast CSC agent, salinomycin, and the clinically used metallodrug, cisplatin. Mechanistic studies indicate that the cobalt(III) complex 6 induces its anti-breast CSC effect by entering breast CSCs, penetrating the nuclei, damaging nuclear DNA and triggering caspase-dependent apoptosis. The cytotoxic mechanism of action of the cobalt(III) complex 6 is also dependent on the modulation of cyclooxygenase-2 (COX-2) expression. This work highlights the anti-breast CSC properties of cobalt(III) coordination complexes with non-steroidal anti-inflammatory drugs (NSAIDs) and more widely spotlights the importance of metallopharmaceuticals in the development of new anticancer agents that can tackle chemotherapeutic-resistant sub-populations.

(1) Background: Familial adenomatous polyposis (FAP) is a hereditary condition characterized by the development of numerous adenomas in the large intestine, often necessitating colectomy due to an elevated risk of colorectal cancer. Despite surgical intervention, adenomas frequently recur, underscoring the importance of ongoing surveillance. This study evaluates the outcomes of a 12-year endoscopic follow-up after colectomy and gastrointestinal reconstruction for FAP. (2) Methods: A retrospective analysis was conducted on 41 FAP patients who underwent at least one postoperative endoscopic examination. Assessments of the pouch or rectum were performed every 12–18 months following ileorectal anastomosis and every 18–24 months after ileal pouch–anal anastomosis. Follow-up biopsies were assessed using the adopted Spigelman classification. (3) Results: Postoperative pathology revealed invasive colorectal cancer in three patients. Abdominoperineal resection was performed in two cases due to secondary invasive carcinoma, and one T1 tumor was radically removed with ESD. One patient underwent radical pouch excision following a nodal pelvic recurrence of rectal cancer. Over a 12-year observation period, the mean Spigelman score increased by 2 points, and the proportion of patients with low-grade polypoid lesions decreased. The quantity or size of polyps increased in 24 patients, decreased in 8 patients, and remained stable in 9 patients. In four patients, granular, laterally spreading tumors were discovered in the rectal stump. (4) Conclusions: Regular endoscopic surveillance in FAP patients facilitates early identification of neoplastic and inflammatory changes. The downstaging potential highlights the effectiveness of early interventions. While the Spigelman classification assessed polyps well, it did not predict cancer occurrence. A notable number of patients had invasive cancer at the time of surgery, underscoring the importance of early surgical qualification, which is particularly crucial for identifying upstaging or secondary cancer.

Simple Summary: Adenocarcinoma of the ampulla of Vater (AAC) is a rare cancer that arises from various histologic subtypes, creating a diverse group of tumors in need of new therapeutic strategies. This study examines the expression of epidermal growth factor receptor (EGFR), human epidermal growth factor receptor 2 (HER2), and c-Met in AAC to explore their potential as druggable targets. Among 87 patients, EGFR overexpression was found in 87.4%, HER2 in 11.5%, and c-Met in 50%. EGFR overexpression was more common in the pancreatobiliary subtype and linked to a higher histologic grade. EGFR-positive AAC patients had worse disease-free and overall survival compared to EGFR-negative patients. Although HER2-positive AAC showed a trend towards shorter survival, it was not statistically significant. In systemic disease, survival outcomes were unaffected by EGFR, HER2, and c-Met expression, although the HER2-positive group tended towards worse progression-free survival. These results highlight the need for further research to evaluate targeted treatments in AAC patients with these protein expressions. Adenocarcinoma of the ampulla of Vater (AAC) is a rare malignancy with heterogeneous tumors arising from various histologic subtypes, necessitating new therapeutic strategies. This study examines epidermal growth factor receptor (EGFR), human epidermal growth factor receptor 2 (HER2), and c-Met expression in AAC, given their potential as druggable targets. Among 87 patients who underwent curative resection, EGFR overexpression was found in 87.4%, HER2 in 11.5%, and c-Met in 50%. EGFR overexpression was more common in the pancreatobiliary subtype (p = 0.018) and associated with a higher histologic grade (p = 0.008). HER2 did not correlate with clinicopathological features, while c-Met was more common in node-negative groups (p = 0.004) and often co-expressed with EGFR (p = 0.049). EGFR-positive patients had worse disease-free (HR = 2.89; 95% CI, 1.35–6.20; p = 0.061) and overall survival (HR = 6.89; 95% CI, 2.94–16.2; p = 0.026) than EGFR-negative patients. HER2-positive AAC showed a trend towards shorter survival, although not statistically significant, and c-Met had no impact on survival outcomes. In the context of systemic disease, survival outcomes did not vary according to EGFR, HER2, and c-Met expression, but the HER2-positive group showed a trend towards inferior progression-free survival (HR = 1.90; 95% CI, 0.56–6.41; p = 0.166). This study underscores the potential of EGFR, HER2, and c-Met as targets for personalized therapy in AAC, warranting further research to evaluate targeted treatments. [ABSTRACT FROM AUTHOR]

Simple Summary: This study aimed to assess the 3-year time to relapse (TTR) and overall survival (OS) of melanoma, including acral and mucosal subtypes, treated with anti-PD-1 antibody (Ab) or the combination of dabrafenib and trametinib. The 3-year TTR of the acral and mucosal types was 28.1% and 38.5%, respectively. The acral subtype and TT were detected as important prognostic factors. In the 3-year OS, only tumor ulceration was associated with the OS in both univariate and multiple analyses. There was no significant difference in baseline or treatment-related factors of the mucosal type (p > 0.05). This study suggests that both acral and mucosal types in the adjuvant setting are less effective than non-acral cutaneous melanoma at the 3-year TTR. Background: Adjuvant therapy has improved the clinical prognosis for postoperative melanoma patients. However, the long-term efficacy of this therapy on the melanoma acral and mucosal subtypes has not been fully evaluated in previous trials. This study assessed the 3-year recurrence-free survival and overall survival of patients with melanoma, including the acral and mucosal subtypes, treated with anti-PD-1 antibody (Ab) or with the combination of the BRAF and MEK inhibitors dabrafenib and trametinib. Methods: We retrospectively analyzed both the 3-year time to relapse (TTR) and overall survival (OS) of 120 patients treated with anti-PD-1 antibody (Ab), or with the combination of dabrafenib and trametinib. Results: The overall median TTR was 18.4 months, with a range of 0.69 to 36 months. The 3-year TTR of the acral and mucosal types was 28.1% and 38.5%, respectively. Baseline tumor thickness (TT) and acral type were associated with the TTR in subgroup analysis. Moreover, we classified 104 acral and non-acral cutaneous patients into the anti-PD-1 Abs or dabrafenib plus trametinib combined therapies cohort in multiple analyses. The acral subtype and TT were detected as important prognostic factors. In the 3-year OS, only tumor ulceration was associated with the OS in both univariate and multiple analyses. There was no significant difference in baseline or treatment-related factors of the mucosal type (p > 0.05). Conclusion: This study suggests that adjuvant therapy is more effective with non-acral cutaneous melanoma than either the acral or mucosal types at the 3-year TTR endpoint. [ABSTRACT FROM AUTHOR]

Simple Summary: Traditionally, the upper border of whole pelvic radiotherapy fields for cervical cancer was set using vertebral landmarks, potentially missing a part of the common iliac lymph node (CIN). This retrospective study investigated the impact of insufficient radiation coverage of CIN in stage IB2-IIB cervical cancer treatment. We compared outcomes between patients with full CIN coverage and those with partial coverage. Our results showed that patients with full CIN coverage had significantly better outcomes, including lower recurrence rates and higher survival rates. These findings suggest that using vascular anatomy (aortic bifurcation) as a guide for setting the upper border of radiation fields may be more effective than relying on vertebral landmarks. Our study highlights the importance of ensuring comprehensive coverage of the CIN area in cervical cancer treatment, which may influence future radiotherapy practices by encouraging the use of vascular landmarks for field border definition. This study investigates the impact of insufficient common iliac lymph node (CIN) irradiation on treatment outcomes in patients with stage IB2-IIB cervical cancer receiving concurrent chemoradiotherapy (CCRT). We retrospectively analyzed 68 patients with Federation of Gynecology and Obstetrics stage IB2-IIB, treated with weekly cisplatin-based CCRT from 2008 to 2018. Patients received external-beam whole pelvic radiotherapy (WPRT) and concurrent cisplatin chemotherapy, followed by high-dose-rate brachytherapy. The WPRT upper border was at L4-5 in 61 patients and L3-4 in 7 patients. Thirty-seven patients had the CIN area fully included (full-CIN group), while 31 had partial inclusion (partial-CIN group). Recurrence rates and survival outcomes were analyzed over a median follow-up of 111 months. Patient characteristics and the irradiated dose were comparable. Treatment failure occurred in three patients (8.1%) in the full-CIN group and in six patients (19.4%) in the partial-CIN group, with CIN and para-aortic lymph node recurrence in two and one patients, respectively. The 5-year cumulative recurrence rate was 0% for the full-CIN group and 11.4% for the partial-CIN group (p = 0.04). Cause-specific survival was 100% vs. 87.1% (p = 0.025), and the overall survival was 94.3% vs. 87.1% (p = 0.44). Fully including the CIN area in WPRT is crucial for stage IB2-IIB cervical cancer. Vascular anatomical margins should be considered over vertebral landmarks. [ABSTRACT FROM AUTHOR]

Simple Summary: Apart from skin cancer, prostate cancer is the most prevalent cancer in men. The treatment options typically entail active surveillance, surgery, radiation, or a combination of the above. The treatment options for recurrent disease also include surgery, radiation, and focal therapy. In this review, we look at the use of cryoablation for recurrent prostate cancer following radiation treatment. The treatment options for prostate cancer typically entail active surveillance, surgery, radiation, or a combination of the above. Disease recurrence remains a concern, with a wide range of recurrence rates having been reported in the literature. In the setting of recurrence, the salvage treatment options include salvage prostatectomy, salvage high-intensity focused ultrasound (HIFU), stereotactic body radiotherapy (SBRT), salvage brachytherapy, and salvage cryoablation. In this review, we analyze the currently available data related to salvage cryoablation for recurrent prostate cancer following radiation. [ABSTRACT FROM AUTHOR]

Simple Summary: This study aimed to evaluate the derived neutrophil to lymphocyte ratio (dNLR) in predicting the prognosis of patients with locally advanced oral squamous cell carcinoma, as well as the survival benefits from induction chemotherapy with docetaxel, cisplatin, and 5-fluorouracil (5-FU). The dNLR is an independent negative predictive factor for the disease. Patients with cTNM stage III disease and a low dNLR may benefit from induction chemotherapy. Background: This study aimed to evaluate the derived neutrophil to lymphocyte ratio (dNLR) in predicting the prognosis of patients with locally advanced oral squamous cell carcinoma (LAOSCC) and to assess the survival benefits from docetaxel, cisplatin, and 5-fluorouracil (5-FU) (TPF) induction chemotherapy (IC). Methods: Patients from a phase III trial involving TPF IC in stage III/IVA OSCC patients (NCT01542931) were enrolled. Receiver operating characteristic curves were constructed, and the area under the curve was computed to determine dNLR cutoff points. Kaplan–Meier survival estimates and Cox proportional hazards models were used for longitudinal analysis. Results: A total of 224 patients were identified (median age: 55.4 years; range: 26 to 75 years; median follow-up: 90 months; range: 3.2 to 93 months). The cutoff point for the dNLR was 1.555. Multivariate analysis showed that the dNLR was an independent negative predictive factor for survival (overall survival (OS): hazard ratio (HR) = 1.154, 95% confidence interval (CI): 1.018–1.309, p = 0.025; disease-free survival (DFS): HR = 1.123, 95% CI: 1.000–1.260, p = 0.050; local recurrence-free survival (LRFS): HR = 1.134, 95% CI: 1.002–1.283, p = 0.047; distant metastasis-free survival (DMFS): HR = 1.146, 95% CI: 1.010–1.300, p = 0.035). A low dNLR combined with cTNM stage III disease predicted benefit from TPF IC for the patients [OS (χ2 = 4.674, p = 0.031), DFS (χ2 = 7.134, p = 0.008), LRFS (χ2 = 5.937, p = 0.015), and DMFS (χ2 = 4.832, p = 0.028)]. Conclusions: The dNLR is an independent negative predictive factor in LAOSCC patients. Patients with cTNM stage III disease and a low dNLR can benefit from TPF IC. [ABSTRACT FROM AUTHOR]

Simple Summary: The management of the axilla for post-mastectomy breast cancer patients who develop a chest wall recurrence (CWR) remains to be established. This study aimed to determine if omitting axillary staging surgery for these patients resulted in an increased risk of second recurrence. A total of 194 patients with CWR, with a median follow-up of 59.5 (IQR 27.3–105) months, were analysed. There was no statistically significant difference in second recurrences between patients with or without axillary surgery during the excision of the CWR. Background: The management of the axilla in breast cancer patients with isolated chest wall recurrence (CWR) after mastectomy remains controversial. Although sentinel lymph node biopsy (SLNB) for restaging is feasible, its role is unclear. We aimed to determine if the omission of axillary restaging surgery in female patients with operable presumably isolated CWRs could result in an increased risk of second recurrences. Methods: In this retrospective multicentre study, patients who developed CWRs were reviewed. We excluded patients with suspected or concomitant regional/distant metastases, bilateral cancers and patients without CWR surgery. Patients' demographics, pathological data and subsequent recurrences were collected from a prospective database and were compared between patients with axillary lymph node dissection (ALND) and/or SLNB versus no axillary operation at CWR. Findings: A total of 194 patients with CWRs were eligible. The median age at CWR was 56.0 (IQR 47.0–67.0) years old. At recurrence, 8 (4.1%), 5 (2.6%) and 181 (93.3%) patients had ALND, SLNB and no axillary operation, respectively. Patients with no axillary surgery during CWR were associated with, at primary cancer, a lower incidence of ductal carcinoma in situ as diagnosis (p = 0.007) and older age (p = 0.022). Subsequent ipsilateral axillary (p = 0.768) and second recurrences (p = 0.061) were not statistically different between patients with and without axillary surgery at CWR on median follow-up of 59.5 (IQR 27.3–105) months. Interpretation: In patients without evidence of concomitant regional or distant metastasis at CWR diagnosis, omission of axillary restaging surgery was not associated with an increased ipsilateral axillary or second recurrences on long-term follow-up.

Simple Summary: Patients with stage IIB and IIC melanoma are considered to have high-risk localized disease and, in some cases, demonstrate worse recurrence-free and overall survival than patients with stage IIIA and even IIIB disease. The mainstay of treatment for patients with high-risk clinical stage II melanoma is surgical resection of the primary tumor and sentinel lymph node biopsy (SLNB), which confers accurate pathologic staging and prognostication for further treatment decisions. Building on the success of adjuvant therapy for stage III melanoma, the KEYNOTE-716 and CheckMate 76K trials found improved recurrence-free survival for patients with high-risk stage II melanoma with adjuvant pembrolizumab and nivolumab, respectively, after complete resection with SLNB. Given these findings, the National Comprehensive Cancer Network now recommends discussing adjuvant pembrolizumab or nivolumab with patients with high-risk stage IIB/C melanoma, weighing the risks of recurrence against the risks of treatment-related adverse events when making the decision regarding adjuvant therapy. Melanoma is the fifth most common cancer in the United States and accounts for the majority of all skin cancer-related deaths, making it the most lethal cutaneous malignancy. Systemic adjuvant therapy for stage IIB-IV melanoma is now approved for patients who have undergone surgical resection, given the appreciable risk of recurrence and mortality in this patient population. Despite the lower stage, high-risk stage II melanoma (stage IIB/IIC) can often exhibit an even more aggressive course when compared to stage IIIA/IIIB disease, thus justifying consideration of adjuvant therapy in these patients. In this review, we highlight the current standard of practice for the treatment of stage IIB/C melanoma, with a focus on adjuvant therapies supported by published landmark clinical trials, including anti-PD-1 therapy. Notably, adjuvant therapies approved thus far in this patient population have demonstrated an improvement in recurrence-free survival, while their impact on overall survival is pending. Finally, this review highlights currently ongoing trials and future directions for research and treatment possibilities for high-risk clinical stage II melanoma. [ABSTRACT FROM AUTHOR]

Simple Summary: Tertiary lymphoid structures (TLS) arise in non-lymphoid tissues due to inflammation or cancer and play a key role in adaptive immune responses. In this study, we analyzed the TLS maturity in 78 patients with pathological T4 colorectal cancer (CRC). Mature TLS, identified by organized T (CD3+) and B (CD20+) lymphocytes with Ki-67-positive B cells, have been linked to microsatellite instability and improved cancer-specific and post-recurrence survival. High tumor Ki-67 expression correlated with poorer outcomes. The absence of mature TLS independently predicted poor survival. Tumors with mature TLS showed a higher infiltration of CD3+ T cells, FOXP3+ T cells, and CD86+ immune cells, including M1-like macrophages. Focusing on the Ki-67 expression pattern, the simultaneous evaluation of TLS maturity and tumor proliferation potency is suggested to be a potential prognostic indicator in CRC. Tertiary lymphoid structures (TLSs) are complex lymphocyte clusters that arise in non-lymphoid tissues due to inflammation or cancer. A mature TLS with proliferating germinal centers is associated with a favorable prognosis in various cancers. However, the effect of TLS maturity on advanced colorectal cancer (CRC) remains unexplored. We analyzed the significance of TLS maturity and tumor Ki-67 expression in surgically resected tumors from 78 patients with pathological T4 CRC. Mature TLS was defined as the organized infiltration of T and B cells with Ki-67-positive proliferating germinal centers. We analyzed the relationship between TLS maturity and intratumoral immune cell infiltration. Mature TLS with germinal center Ki-67 expression was associated with microsatellite instability and improved survival; however, high tumor Ki-67 expression was associated with poor survival in the same cohort. Multivariate analysis identified the absence of mature TLS as an independent predictor of poor post-recurrence overall survival. Intratumoral infiltration of T lymphocytes and macrophages was significantly elevated in tumors with mature TLS compared to those lacking it. High Ki-67 levels and absent mature TLS were identified as poor prognostic factors in advanced CRC. Mature TLS could serve as a promising marker for patients at high-risk of CRC.

Simple Summary: This research investigates whether a diagnostic technique called ureteroscopy (URS), performed before surgery for removing the kidney and ureter, influences the likelihood of cancer recurrence in the bladder in patients with upper tract urothelial carcinoma (UTUC). Data from a multicentre international registry were analysed to compare patients who underwent URS before their surgery with those who did not. The study found that patients who had URS prior to surgery experienced a higher rate of cancer recurrence in the bladder. These results highlight the need for careful consideration of the use of URS in the diagnostic process for UTUC, as it could affect long-term outcomes. This information is crucial for clinicians in optimizing treatment strategies and improving patient care. (1) Introduction: Diagnostic ureteroscopy (URS) is an important component in the workup of upper tract urothelial carcinoma (UTUC). Whether URS was associated with increased recurrence in the bladder was not fully concluded. The current study aimed to evaluate the implication of URS on the incidences of intravesical recurrence following radical nephroureterectomy (RNU) in non-metastatic UTUC patients without prior history of bladder cancer via multi-institutional data. (2) Patients and Methods: Data were obtained from the Clinical Research Office of the Endourology Society Urothelial Carcinomas of the Upper Tract (CROES-UTUC) registry, a prospective, multicentre database. Patients with non-metastatic UTUC treated with RNU were divided into two groups: those undergoing upfront RNU and those having diagnostic URS prior to RNU. Intravesical recurrence-free survival (IVRS) was the primary endpoint, evaluated through Kaplan–Meier analysis and multivariate Cox regression. Cases with adequate follow-up data were included. (3) Results: The analysis included 269 patients. Of these, 137 (50.9%) received upfront RNU and 132 (49.1%) received pre-RNU URS. The URS group exhibited an inferior 24-month IVRS compared to the upfront RNU group (HR = 1.705, 95% CI = 1.082–2.688; p = 0.020). Multivariate analysis confirmed URS as the only significant predictor of IVR (p = 0.019). Ureteric access sheath usage, flexible ureteroscopy, ureteric biopsy, retrograde contrast studies, and the duration of URS did not significantly affect IVRS. (4) Conclusions: Diagnostic URS prior to RNU was found to be associated with an increased risk of IVR in patients with UTUC. The risk was not significantly influenced by auxiliary procedures during URS. Physicians were advised to meticulously evaluate the necessity of diagnostic URS. [ABSTRACT FROM AUTHOR]

Simple Summary: Sarcomas are a heterogeneous group of tumors that arise from mesenchymal tissue, including adipose, bone, cartilage, skeletal muscle, and smooth muscle. Because of their rarity, optimal treatment planning requires discussion among sarcoma-experienced subspecialists. Studies have shown that treatment guided by multidisciplinary tumor boards (MTBs) is associated with better compliance with clinical practice guidelines and, in some cases, increased survival. The role of radiologists in the MTB setting is valuable in assessing disease in patients with sarcoma; however, radiologists' recommendations may differ from the MTB's consensus. This study highlights the discordance between the disease assessment and the clinical recommendations provided by radiologists and MTBs and encourages all radiologists caring for patients with sarcoma to participate in MTBs to best align their interpretations with optimal clinical management and make multidisciplinary aligned recommendations whenever feasible. Multidisciplinary tumor boards (MTBs) facilitate decision-making among subspecialists in the care of oncology patients, but the mechanisms by which they enhance outcomes remain incompletely understood. Our aim was to measure the agreement between sarcoma MTBs and radiology reports' disease assessment and management recommendations. This single-center IRB-approved retrospective study evaluated cases presented at a weekly sarcoma MTB from 1 August 2020 to 31 July 2021. Cases without clinical notes, imaging studies, or radiology reports were excluded. The data collected included the patient's clinical status at the time of the MTB, the treatment response assessment by the MTB and radiologists (stable disease; partial response; complete response; progressive disease/recurrence), and the recommendations of the radiology reports and of the MTB. The agreement between the initial radiologist review and MTB on disease assessment and recommendations was analyzed using kappa statistics. In total, 283 cases met the inclusion criteria. Radiology reports provided recommendations in 34.3% of cases, which were adhered to by the ordering providers in 73.2% of cases. The agreement between MTBs and radiology reports was moderate in disease assessment (86.2% agreement; κ = 0.78; p < 0.0001) and negligible in recommendations (36% agreement; κ = 0.18; p < 0.0001). Radiologists were more likely to assign progressive disease/recurrence than MTBs (54.4% vs. 44.4%; p < 0.001) and to recommend short-term imaging follow-up more commonly than MTBs (46.4% vs. 21.7%; p < 0.001). At a tertiary care center, radiologists' isolated interpretations of imaging findings and management recommendations frequently differ from the MTB's consensus, reflecting the value of multidisciplinary discussions incorporating the patient's clinical status and the available treatment options into the final radiographic assessment.

Simple Summary: The chemotherapy combination rituximab, gemcitabine, and dexamethasone (R-GDP), followed by high-dose chemotherapy and autologous stem cell transplantation, is one of the standards of care for relapsed or refractory B-cell non-Hodgkin lymphoma (R/R NHL). Complete metabolic response before transplantation is the most important prognosis factor for a long duration of remission. Selinexor is an oral, selective inhibitor of the nuclear export compound (XPO1). For heavily pretreated patients with DLBCL, the single drug selinexor has previously shown an overall response rate of 29%. In this study, we evaluated selinexor in combination with RGDP for patients with R/R B-cell lymphoma. The results from our phase I clinical study indicate that weekly selinexor plus RGDP has a generally tolerable safety profile and durable efficacy in R/R B-NHL. Purpose: Selinexor is an oral selective inhibitor of exportine-1 (XPO1) with efficacy as a single agent in heavily pretreated diffuse large B-cell lymphoma (DLBCL). We conducted a study investigating the combination of selinexor with rituximab and platinum-based chemotherapy in B-cell lymphoma. Patients and methods: We conducted a phase 1b, dose-escalation, and expansion trial, which enrolled patients with relapsed or refractory B-cell non-Hodgkin lymphoma. Patients received oral selinexor according to a 3 + 3 design in combination with rituximab and dexamethasone, high-dose cytarabine, oxaliplatine (DHAOX) or gemcitabine, dexamethasone, and cisplatin (GDP) chemotherapy. Results: A total of 39 patients were enrolled, 27 during the escalation phase and 12 during the expansion phase. Most patients had diffuse large B-cell lymphoma (DLBCL; 77%). Group R-DHAOX was prematurely closed to inclusion due to a recommendation from the French drug agency, independent of this trial. A recommended phase 2 dose (RP2D) of selinexor in association with R-GPD was established at 40 mg on days 1, 8, and 15 of each 21-day cycle. In a population of 18 patients treated at this dose of selinexor, the most frequent grade 3–4 adverse events were hematological. With this regimen, seven obtained a complete metabolic response and five a partial response. The median PFS was 5.8 months. Conclusions: Among the patients with R/R B-cell lymphoma, selinexor at a weekly dose of 40 mg with R-GDP is feasible for outpatients, with a generally acceptable safety profile.

Simple Summary: Glioblastoma is the most common and aggressive brain tumor in adults. Despite surgery, radiation, and chemotherapy, survival rates remain low, which emphasizes the urgent need for improved therapies. Current preclinical models use untreated tumors, which do not reflect the clinical scenario where patients already receive initial treatments. This review examines the effects of current treatments on the properties of recurrent tumors and evaluates preclinical models that incorporate these standard treatments to better mimic real patient conditions. Improving these models could help to identify more effective treatments, potentially leading to better outcomes for glioblastoma patients. Glioblastoma (GBM) presents a significant public health challenge as the deadliest and most common malignant brain tumor in adults. Despite standard-of-care treatment, which includes surgery, radiation, and chemotherapy, mortality rates are high, underscoring the critical need for advancing GBM therapy. Over the past two decades, numerous clinical trials have been performed, yet only a small fraction demonstrated a benefit, raising concerns about the predictability of current preclinical models. Traditionally, preclinical studies utilize treatment-naïve tumors, failing to model the clinical scenario where patients undergo standard-of-care treatment prior to recurrence. Recurrent GBM generally exhibits distinct molecular alterations influenced by treatment selection pressures. In this review, we discuss the impact of treatment—surgery, radiation, and chemotherapy—on GBM. We also provide a summary of treatments used in preclinical models, advocating for their integration to enhance the translation of novel strategies to improve therapeutic outcomes in GBM.
