According to the World Health Organization, cancer is a leading cause of death worldwide. Several bioactive molecules, such as peptides, have been developed to adjuvate in cancer therapy. Previous evidence showed that the peptides KLKKNL, MLKSKR, KKYRVF, FRTKKK, and SVVAKAPVGKR, identified from a protein fraction of S. hispanica seeds, may serve as adjuvant therapy based on their physicochemical properties. Thus, this work aimed to evaluate the cytotoxic effect of these peptides on cancer cells through in silico and in vitro assays. Molecular dynamics simulations were performed to determine the interaction of the peptides with a cancer cell membrane model. Additionally, cell viability assays were performed to assess the effect of the peptides on MCF-7, Caco2, HepG2, DU145, HeLa, and hFB cell lines, and on erythrocytes. Both in silico and in vitro evaluations reported that KLKKNL, MLKSKR, KKYRVF, FRTKKK, and SVVAKAPVGKR interacted with the cancer cell membrane, significantly decreasing their viability. Molecular dynamics of KKYRVF exhibited a stable interaction with the cancer cell membrane model (-3.2 Kcal·mol-1), and experimentally showed selective cytotoxicity on the cancer cell lines. These findings support the continuous assessment of these peptides as adjuvants in cancer treatment for their potential as ingredients in functional foods or nutraceuticals. [Display omitted] • Lung, colorectum, liver and breast cancers are the top types of cancer to cause death. • In silico and in vitro assays successfully predict the anticancer activity of peptides. • KLKKNKL, MLKSKR, KKYRVF, FRTKKK, and SVVAKAPVGKR report anticancer properties. • The five peptides reported interaction with the cancer cell membrane in silico. • The predictions were validated since the peptides decreased the cancer cells' viability.

The current evidence for the use of nanoparticle albumin-bound paclitaxel (nab-PTX) for adjuvant breast cancer chemotherapy is insufficient. The present study aimed to assess the efficacy and toxicity of nab-PTX in comparison with solvent-based paclitaxel (sb-PTX) in postoperative adjuvant breast cancer treatment. A total of 345 patients were included in the study and separated into nab-PTX (n=289) and sb-PTX (n=56) groups based on the type of taxane used in the adjuvant chemotherapy regimen. The study evaluated the baseline characteristics in both groups and the risk factors for postoperative recurrence of mammary cancer. Furthermore, data concerning disease-free survival (DFS) and adverse effects were obtained and analyzed, and group confounding variables were addressed using 1:2 propensity score matching (PSM). Comparisons before PSM revealed significant differences in baseline characteristics including age, underlying disease, lymph node involvement, vascular invasion, human epidermal growth factor receptor 2 and axillary surgery (P<0.05). Following PSM, there were 90 patients in the nab-PTX group and 56 in the sb-PTX group, with no significant differences in the baseline differences (P>0.05). Before PSM, the 73-month DFS rate was 97.9% in the nab-PTX group compared with 91.1% in the sb-PTX group. However, there were no significant differences between the groups before or after PSM (P=0.15 and P=0.49, respectively). Additionally, Cox regression analysis demonstrated a significantly lower chance of recurrence in patients aged >45 years [hazard ratio (HR), 0.197; 95% confidence interval (CI), 0.052-0.753; P=0.018], whereas underlying disease (HR, 5.352; 95% CI, 1.310-21.854; P=0.019) and lymph node infiltration (HR, 8.930; 95% CI, 1.121-71.161; P=0.039) significantly increased the risk of recurrence. Regarding safety, the sb-PTX group had a significantly greater incidence of anaphylaxis, whereas the nab-PTX group had significantly increased rates of anemia and peripheral neuropathy (P<0.05). In summary, the 73-month DFS rate of the nab-PTX cohort exceeded that of the sb-PTX cohort, but no significant difference was detected between them. Underlying disease, lymph node metastasis and an age of ≤45 years are significant predictors of postoperative recurrence of breast cancer. [ABSTRACT FROM AUTHOR]

Background: Breast cancer patients have an increased risk of cardiometabolic disease and for many patients, adjuvant therapy causes an altered lipid profile, insulin resistance and inflammation. Previous follow-up studies are inconclusive regarding the duration of therapy-induced inflammation. We examined the acute and persistent changes of adjuvant chemotherapy on inflammatory and metabolic health markers in breast cancer patients. Methods: Plasma levels of IL-6, IL-8, IL-10, IFN-γ, TNF-α, high-sensitivity C-reactive protein (hsCRP) and metabolic health parameters were analyzed before, shortly after and every six months up to two years after adjuvant chemotherapy treatment in 51 postmenopausal early breast cancer (EBC) patients, as well as in 41 healthy age- and BMI-matched controls. A target-specific multiplex assay was applied for cytokine measurements. Results: Before initiation of adjuvant therapy, plasma IL-8 levels were higher in EBC patients (31%, p = 0.0001). Also, a larger proportion of the patients had a hsCRP level above 2 mg/L (41%) compared to the controls (17%, Χ2 = 5.15, p = 0.023). Plasma levels of all five cytokines, but not hsCRP, were significantly increased after compared to before adjuvant chemotherapy (15–48% increase; all p ≤ 0.05). Already six months after ending chemotherapy treatment, all plasma cytokine levels were significantly reduced and close to pre-chemotherapy levels. Adjuvant chemotherapy caused a worsened lipid profile (increased triglycerides, lower HDL levels), insulin resistance and increased plasma insulin levels that remained high during the first year after chemotherapy. Conclusion: Postmenopausal women with EBC have temporarily increased plasma levels of pro-inflammatory cytokines after adjuvant chemotherapy. Although transient, the therapy-induced increase in plasma cytokine levels, together with dyslipidemia and insulin resistance, may contribute to cardiometabolic risk in breast cancer patients treated with adjuvant chemotherapy. Trial registration: The clinical trial (registration number NCT03784651) was registered on www.clinicaltrials.gov on 24 December 2018. [ABSTRACT FROM AUTHOR]

Simple Summary: The study evaluated the long-term outcomes of chemoradiotherapy (CRT) with S-1 after limited surgery for T1 or T2 lower rectal cancer. The 3-year and 5-year relapse-free survival rates were 90.17% and 85.87%, respectively, showing favorable outcomes for T1 cancer patients, with effective anal function preservation. However, further treatment is needed to improve outcomes for T2 cancer patients. Background: The short-term outcomes of chemoradiotherapy (CRT) with S-1 (a combination of tegafur, gimeracil, and oteracil) following limited surgery for patients with T1 or T2 lower rectal cancer have shown encouraging results. Objectives: This study was designed to delve deeper into the long-term outcomes of CRT with S-1 after limited surgery, with the goal of evaluating both the long-term efficacy and potential risks associated with this treatment approach in patients diagnosed with T1 or T2 lower rectal cancer. Methods: This was conducted as a multicenter, single-arm, prospective phase II trial. The patient population consisted of individuals clinically diagnosed with either T1 or T2 lower rectal or anal canal cancer, with a maximum tumor diameter of 30 mm and classified as N0 or M0. Patients underwent local excision or endoscopic resection. After surgery, CRT with S-1 was administered to patients meeting several criteria, including the confirmation of well-differentiated or moderately differentiated adenocarcinoma, negative surgical margins, submucosal invasion depth of ≥1000 µm, and high tumor-budding grade (2/3). The primary endpoint of this study was relapse-free survival, while secondary endpoints included local recurrence-free survival, overall survival, anal sphincter preservation rate, and safety. Results: A total of 52 patients were included, with pathological diagnoses revealing T1 in 36 patients and T2 in 16 patients. The 3-year and 5-year relapse-free survival rates were 90.17% and 85.87%, respectively. The 3-year and 5-year local recurrence-free survival rates were 90.17% and 88.07%, respectively, while the 3-year and 5-year overall survival rates were 94.03% and 91.94%, respectively. Conclusions: CRT with S-1 after limited surgery for T1 lower rectal cancer demonstrated favorable outcomes in terms of recurrence, survival, and local control rates while effectively maintaining anal function in patients. However, further treatment approaches may be necessary to improve outcomes for patients diagnosed with stage T2 lower rectal cancer [ABSTRACT FROM AUTHOR]

Simple Summary: This study aimed to identify prognostic factors by combining clinicopathologic parameters with tumor microenvironment (TME) biomarkers in patients with locally advanced rectal cancer (LARC) who underwent surgery following neoadjuvant chemoradiotherapy (nCRT). We analyzed CD8+ T cells, CXCR3, CXCL10, and α-SMA using immunohistochemical staining and incorporated AI-powered digital pathology to assess the spatial TME. Our findings showed that high expression of CD8+ T cells, CXCR3 in tumor-infiltrating lymphocytes (TILs), and an inflamed phenotype were associated with better recurrence-free survival (RFS). However, these factors were not predictive of overall survival (OS). Patients with an immune-desert phenotype had a poor prognosis regardless of pathologic stage or the administration of postoperative chemotherapy. These results suggest that CD8+ T cells and AI-powered immune phenotypes, together with clinical factors, can guide personalized treatment strategies in LARC patients post-nCRT and highlight the potential benefits of modifying the tumor immune microenvironment (TiME) to reduce recurrence after surgery. Background/Objectives: The tumor microenvironment (TME) has emerged as a significant prognostic factor. This study aimed to identify prognostic factors by combining clinicopathologic parameters and the TME biomarkers in patients who underwent surgery following neoadjuvant chemoradiotherapy (nCRT) for locally advanced rectal cancer (LARC). Methods: CD8+ T cells, CXCR3, CXCL10, and α-smooth muscle actin (α-SMA) were analyzed via immunohistochemical staining. We also incorporated AI-powered digital pathology to assess the spatial TME. The associations between these biomarkers, clinicopathologic parameters, and survival outcomes were evaluated. Results: CD8+ T cell expression, CXCR3 expression in tumor-infiltrating lymphocytes (TILs), and immune phenotypes were correlated. LARC patients with a high expression of CD8+ T cells, CXCR3 in TILs, and an inflamed phenotype had a significantly better prognosis than their counterparts did. In the multivariate analysis, the expression of CD8+ T cells and the inflamed/immune-excluded phenotype were significant tumor immune microenvironment (TiME) biomarkers for recurrence-free survival (RFS) but not for overall survival (OS). Notably, patients with the immune-desert phenotype had a poor prognosis regardless of pathologic stage, even if postoperative chemotherapy was administered (p < 0.001). Conclusions: CD8+ T cells and AI-powered immune phenotypes, alongside clinical factors, can guide personalized treatment in LARC patients receiving nCRT. A therapeutic strategy to modify the TiME after nCRT could help reduce recurrence after surgery. [ABSTRACT FROM AUTHOR]

Simple Summary: As the population ages, the prevalence of frailty syndrome increases, particularly among elderly patients with rectal cancer. Frail patients are more vulnerable to stressors and may struggle with the standard treatment for locally advanced rectal cancer, which typically includes chemoradiotherapy, surgery, and chemotherapy. While this approach shows good clinical results, it may not be suitable for all frail patients due to potential side effects. Since frail patients are underrepresented in clinical trials, this article highlights the need for new treatment strategies for them. Routine screening for frailty in hospitalized patients is recommended, and treatment should be planned by a multidisciplinary team, including specialists such as geriatricians and oncologists. Adapting guidelines and treatment plans for frail patients is crucial for improving outcomes in this growing population. Owing to the gradual aging of today's population, an increase in the prevalence of frailty syndrome has been noticed. This complex state of health, characterized by decreased resilience and tolerance with concurrent increased vulnerability to stressors and adverse health-related factors, has drawn researchers' attention in recent years. Rectal cancer, which constitutes ~30% of all colorectal cancers, is a disease noticeably related to the elderly. In its locally advanced form, it is conventionally treated with trimodal therapy—neoadjuvant chemoradiotherapy followed by total mesorectal excision and adjuvant chemotherapy. Despite its good clinical outcomes and improvement in rectal cancer local control, as evidenced by clinical trials, it remains unclear if all frail patients benefit from that approach since it may be associated with adverse side effects that cannot be handled by them. As old patients, and frail ones even more noticeably, are poorly represented in the clinical trials describing outcomes of the standard treatment, this article aims to review the current knowledge on the trimodal therapy of rectal cancer with an emphasis on novel approaches to rectal cancer that can be implemented for frail patients.

BACKGROUND: Betel nut chewing is a significant risk factor for oral cancer due to arecoline, its primary active component. Resveratrol, a non‐flavonoid polyphenol, possesses anti‐cancer properties. It has been shown to inhibit arecoline‐induced oral malignant cells in preliminary experiments but the underlying mechanism remains unclear. This research therefore aimed to explore the potential therapeutic targets of resveratrol in treating arecoline‐induced oral cancer. METHODS: Data mining identified common targets and hub targets of resveratrol in arecoline‐induced oral cancer. Gene set variation analysis (GSVA) was used to score and validate the expression and clinical significance of these hub targets in head and neck cancer (HNC) tissues. Molecular docking analysis was conducted on the hub targets. The effect of resveratrol intervention on hub targets was verified by experiments. RESULTS: Sixty‐one common targets and 15 hub targets were identified. Hub targets were highly expressed in HNC and were associated with unfavorable prognoses. They played a role in HNC metastasis, epithelial‐mesenchymal transition, and invasion. Their expression also affected immune cell infiltration and correlated negatively with sensitivity to chemotherapeutic agents such as bleomycin and docetaxel. Experiments demonstrated that resveratrol down‐regulated the expression of the hub targets, inhibited their proliferation and invasion, and induced apoptosis. CONCLUSION: Resveratrol inhibits the arecoline‐induced malignant phenotype of oral epithelial cells by regulating the expression of some target genes, suggesting that resveratrol may be used not only as an adjuvant treatment for oral cancer, but also as an adjuvant for oral cancer prevention due to its low toxicity and high efficacy. © 2024 Society of Chemical Industry.

Simple Summary: Real-world studies comparing TNT and CRT are vital for advancing the treatment of LARC. Our study provides valuable insights reflecting the diverse patient populations and varied clinical practices encountered and demonstrates the advantage of TNT, providing a superior alternative to standard CRT and potentially enhancing treatment outcomes and quality of life. Total neoadjuvant therapy (TNT) has emerged as a promising approach for managing locally advanced rectal cancer (LARC), aiming to enhance resectability, increase pathological complete response (pCR), improve treatment compliance, survival, and sphincter preservation. This study compares the clinical outcomes of TNT, with either induction or consolidation chemotherapy, to those of the standard chemoradiotherapy (CRT). In this retrospective multi-institutional study, patients with stage II-III LARC who underwent CRT or TNT from seven oncology centers between 2021 and 2024 were retrospectively analyzed. The TNT group was categorized into induction or consolidation groups based on the sequence of chemotherapy and radiotherapy. Clinical and pathological data and treatment outcomes, including pCR, event-free survival (EFS), and overall survival (OS), were analyzed. Among the 276 patients, 105 received CRT and 171 underwent TNT. The TNT group showed significantly higher pCR (21.8% vs. 2.9%, p < 0.001) and lower lymphatic (26.3% vs. 42.6%, p = 0.009), vascular (15.8% vs. 32.7%, p = 0.002), and perineural invasion rates (20.3% vs. 37.6%, p = 0.003). Furthermore, 16.9% of TNT patients opted for non-operative management (NOM), compared to 0.9% in the CRT group (p < 0.001). The median interval between the end of radiotherapy and surgery was longer in the TNT group (17.6 weeks vs. 8.8 weeks, p < 0.001). The 3-year EFS was 58.3% for CRT and 71.1% for TNT (p = 0.06). TNT is associated with higher pCR, lower lymphatic and vascular invasion rates, and higher rates of NOM compared to CRT. This supports the use of TNT as a viable treatment strategy for LARC, offering potential benefits in quality of life. [ABSTRACT FROM AUTHOR]

Indole-3-carbinol (I3C) is a major dietary component produced in Brassica vegetables from glucosinolates (GLS) upon herbivores' attack. The compound is gaining increasing interest due to its anticancer activity. However, reports about improving its level in plants or other sources are still rare. Unfortunately, I3C is unstable in acidic media and tends to polymerize rendering its extraction and detection challenging. This review presents a multifaceted overview of I3C regarding its natural occurrence, biosynthesis, isolation, and extraction procedure from dietary sources, and optimization for the best recovery yield. Further, an overview is presented on its metabolism and biotransformation inside the body to account for its health benefits and factors to ensure the best metabolic yield. Compile of the different analytical approaches for I3C analysis in dietary sources is presented for the first time, together with approaches for its detection and its metabolism in body fluids for proof of efficacy. Lastly, the chemopreventive effects of I3C and the underlying action mechanisms are summarized. Optimizing the yield and methods for the detection of I3C will assist for its incorporation as a nutraceutical or adjuvant in cancer treatment programs. Highlighting the complete biosynthetic pathway and factors involved in I3C production will aid for its future biotechnological production. [ABSTRACT FROM AUTHOR]

Recent studies show increased expression of human epidermal growth factor receptor 2 (HER2) in cervical cancer, but the efficacy of anti‐HER2 therapy remains under‐researched. Here, we present a case of recurrent HER2‐positive serous carcinoma, presumably arising in the cervix, diagnosed by comprehensive genomic profiling, which responded to trastuzumab. The patient underwent a radical hysterectomy with concurrent adjuvant chemoradiotherapy. One year after surgery, the patient experienced recurrence (multiple lymph node metastases). She underwent chemotherapy and subsequent comprehensive genomic profiling, which revealed HER2 positivity. Despite treatment, the lymph node and peritoneal metastases progressed. Therefore, combination chemotherapy with paclitaxel and trastuzumab was initiated. Subsequently, the patient's clinical symptoms improved considerably, and good health was maintained for 8 months. This report highlights the importance of comprehensive genomic profiling and targeted therapies when standard treatments fail. [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.

The study aims to describe couples' changes in sexuality after non-metastatic breast cancer from a longitudinal perspective. Our research question was: how do couples experience the cancer-induced change in sexual frequency and what are the reasons evoked to explain this kind of change over time? Forty heterosexual couples participated in a semi-structured interview three months and two years after surgery. A reflexive thematic analysis was conducted on a specific question about sexuality from a larger interview guide. The results showed that couples follow multiple trajectories regarding sexuality after the onset of oncological treatment. Most couples experienced temporary or more lasting changes, mainly associated with altered body image and pain. Some stopped having sexual activities at the beginning of treatment but resumed sexuality two years later; others were unable to restore sexuality. However, some couples stayed sexually active all along the cancer journey, showing that cessation of any sexual activity is not inevitable. Sexuality represents a significant long-term issue for breast cancer survivors and their partners. Prompt treatment can prevent sexual difficulties from crystallizing, while preserving the individual well-being and the quality of the couple's relationship. Health professionals should be aware of the need to screen early for sexual changes, while reevaluating the couple's situation regularly during care. [ABSTRACT FROM AUTHOR]

Introduction: Esophageal and gastroesophageal junction cancer (EC/GEJC) is a poor prognosis disease with a high risk of recurrence even in patients curatively resected. Adjuvant nivolumab is currently used for patients with completely resected (R0) EC/GEJC who have residual pathologic disease following prior neoadjuvant chemoradiotherapy. This study aimed to determine the cost effectiveness of nivolumab in this indication in France according to the collective perspective excluding indirect costs. Materials and Methods: A simplified four-health-state semi-Markov model was developed to model EC/GEJC patients who have residual disease after neoadjuvant chemoradiotherapy followed by R0 over a 15-year time horizon, comparing adjuvant nivolumab versus surveillance, which was the recommended French clinical practice before immunotherapy arrival. Time-to-recurrence (TTR) from CheckMate 577 was used to inform transition from disease-free to post-recurrence health state; patients who recurred were split according to the distribution of type of recurrence observed during the trial. Post-recurrence survival (PRS) according to the type of recurrence was derived from a real-world registry. Results: Adjuvant treatment with nivolumab led to an incremental survival gain of 1.19 years (+ 34%), mostly in the disease-free state, an incremental cost of €48,634 and QALY of 0.98 resulting in an incremental cost-utility ratio (ICUR) of €49,572/QALY with limited uncertainty. 'Cure assumption' at 5 years had an important impact on the results (€41,115/QALY; − 17%), as that tends to increase life-years and QALYs while costs remain the same. Probabilistic sensitivity analyses confirmed reference ICUR (€52,542/QALY) with 80% probability of nivolumab being cost effective at a willingness-to-pay threshold of €75,000/QALY. Conclusions: Our analysis suggests that adjuvant nivolumab is cost effective in the treatment of EC/GEJC patients who have residual disease after neoadjuvant CRT followed by R0 resection. Compared with previously evaluated cost-effectiveness analyses for other immune-checkpoint inhibitors indicated in metastatic settings, ICUR appears particularly low in this early setting thanks to the important impact on health outcomes and capped treatment duration.

Sinonasal teratocarcinosarcoma (SNTCS) is a rare malignancy characterized by a highly aggressive nature. It mainly arises in the ethmoidal or maxillary sinus. SNTCS has a poor prognosis, with a mean survival rate of 55% at 2 years. Herein, we presented a case of advanced SNTCS successfully treated with surgery followed by chemoradiotherapy plus targeted therapy and reviewed the published literature on this rare entity.

Background Patients with hormone receptor-positive (HR+), human epidermal growth factor receptor-2 negative (HER2−) early breast cancer (EBC) with high-risk clinicopathological features face an increased risk of recurrence. This study explored the evolving treatment landscape and clinical outcomes in patients with EBC using a nationwide database. Patients and Methods The study cohort comprised HR+/HER2−, stages 1-3, patients with EBC who underwent surgery and received adjuvant endocrine therapy (AET) from January 2013 to March 2021. High-risk patients were defined by ≥4 positive axillary lymph nodes, or 1-3 positive lymph node(s) with at least one high-risk feature (histologic grade 3, tumor size ≥5 cm, or Ki-67 ≥20%). A low-risk cohort included patients not meeting the criteria. Survival analysis was conducted with a cutoff of September 2021. Results The study included 4088 eligible patients (1310 high-risk patients and 2778 low-risk patients). High-risk patients were more likely to receive adjuvant chemotherapy and radiotherapy compared to low-risk patients. From 2013 to 2021, an increasing proportion of patients received aromatase inhibitors and ovarian function suppression as part of their AET. The 2-, 5-, and 7-year invasive disease-free survival for high-risk cohort were 90.67%, 75.26%, and 57.10%, respectively, these rates were notably higher for low-risk cohort at 97.14%, 89.85%, and 84.83%. High-risk patients demonstrated a higher risk of recurrence or death compared with low-risk patients (hazard ratio, 2.38; 95% CI, 1.82-3.12). Conclusion In the setting of standard or even intensive AET, patients with EBC with high-risk features still present high recurrence risk, highlighting the urgent need for innovative adjuvant treatment strategies.

Adjuvant therapy is essential in cancer treatment to enhance primary treatment effectiveness, reduce adverse effects, and prevent recurrence. Small molecule inhibitors as adjuvants in cancer immunotherapy aim to harness their immunomodulatory properties to optimize treatment outcomes. By modulating the tumor microenvironment, enhancing immune cell function, and increasing tumor sensitivity to immunotherapy, small molecule inhibitors have the potential to improve patient responses. This review discusses the evolving use of small molecule inhibitors as adjuvants in cancer treatment, highlighting their role in enhancing the efficacy of immunotherapy and the opportunities for advancing cancer therapies in the future.

Cutaneous metastases from squamous cell carcinomas of the head and neck region are uncommon, and their location at the nasal tip is exceptionally rare. A patient, previously treated with surgery and chemoradiation for a hypopharyngeal squamous cell carcinoma, developed several red nodular skin lesions at the nasal tip. Biopsy revealed cutaneous metastasis from the primary tumor. This manifestation was previously described as a "clown nose," given their appearance and location. Skin lesions should raise suspicion of malignancy, despite their location at uncommon places, particularly in patients with previous diagnosed cancer. Clinicians must be aware that metastases from head and neck cancer can present as a "clown nose." [ABSTRACT FROM AUTHOR]

To assess adjuvant treatment patterns on survival in patients with pT3N0M0 esophageal cancer who underwent esophagectomy without neoadjuvant chemoradiotherapy. Stage pT3N0M0 esophageal cancer patients were assessed between 2000 and 2020 from the Surveillance, Epidemiology, and End Results databases. Kaplan–Meier analysis was used to compare overall survival (OS) among various treatment patterns. We identified 445 patients: 252 (56.6%) received surgery alone, 85 (19.1%) received surgery+chemoradiotherapy, 80 (18.0%) underwent surgery+chemotherapy, and 28 (6.3%) received surgery+ radiotherapy. For squamous cell carcinoma, surgery+chemoradiotherapy ([hazard ratio] HR = 1.04, 95% confidence interval (CI): 0.65–1.66; P  = 0.873), surgery+chemotherapy (HR = 0.72, 95% CI: 0.42–1.22; P  = 0.221), and surgery+radiotherapy (HR = 1.33, 95% CI: 0.74–2.39; P  = 0.341) had similar OS compared to surgery alone. For adenocarcinoma, surgery+chemoradiotherapy (HR = 0.51, 95% CI: 0.36–0.74; P  < 0.001) and surgery+chemotherapy (HR = 0.61, 95% CI: 0.42–0.87; P  = 0.006) had better OS compared to surgery alone. However, surgery+radiotherapy had a comparable OS (HR = 0.81, 95% CI: 0.44–1.49; P  = 0.495).Adjuvant treatments did not improve survival in stage pT3N0M0 esophageal squamous cell carcinoma patients. In contrast, adjuvant chemoradiotherapy and chemotherapy were recommended for esophageal adenocarcinoma patients. [ABSTRACT FROM AUTHOR]

Laparoscopic and robotic-assisted techniques have gained popularity, and endometrial cancer (EC) remains a significant health problem among women. Minimally invasive surgical (MIS) therapy options for early endometrial cancer will be evaluated for their effectiveness and safety is the aim of this paper. We also investigate the differences in oncologic outcomes between MIS and open surgery (OS) for individuals with early-stage EC. The patient was diagnosed with early-stage EC and treated with laparoscopic surgery and was the focus of a retrospective analysis. 162 patients with early EC were analyzed, with diagnoses occurring between 2002 and 2022. The patients were fragmented into two groups, one for OS and another for laparoscopic procedures. The total tumor excision and recurrence rates were identical across the two methods, indicating similar oncologic results. Rates of complications were likewise comparable across the two groups. The quality of life ratings of patients with robotic-assisted surgery was higher than those with laparoscopic surgery. Sixty-two (62.2%) of the 162 patients in this research had OS, whereas Fifty-six (57.8%) had MIS. The probability of recurrence of EC from stages III to IV was significanitly higher in women who had OS. Minimally invasive procedures were shown to be effective in treating early-stage EC, and while these findings provide support for their usage, larger multicenter randomized controlled studies are required to verify these results and further examine possible long-term advantages. Patients with early-stage EC, regardless of histologic type, had superior survival rates with MIS compared to OS. [ABSTRACT FROM AUTHOR]

Background and Objectives: Colorectal cancer (CRC) poses a major global health challenge, with high incidence rates and ongoing treatment debates. Adjuvant chemotherapy benefits for high-risk subgroups, particularly stage II disease, remain controversial. This study seeks to clarify this issue by specifically examining the impact of adjuvant chemotherapy on disease-free survival (DFS) and overall survival (OS) in patients diagnosed with T4 colon cancer. Materials and Methods: This retrospective study analyzed patients undergoing radical surgery for T4 colon cancer between 2002 and 2023. Results: Our study of 184 pT4 pN0 colon cancer patients revealed that 79.3% received adjuvant chemotherapy. Multivariate analysis demonstrated significant DFS improvement: a 60% reduction in risk for those who received adjuvant therapy (0.40 95% CI: 0.25–0.62, p < 0.001). Lymphovascular invasion (LVI) and adjuvant treatment were also significantly associated with OS. Adjuvant treatment reduced mortality by 60% (HR: 0.40, 95% CI: 0.23–0.68, p = 0.001). Patients with LVI had a 1.9-fold increase in mortality (HR: 1.94, 95% CI: 1.17–3.20, p = 0.011). These findings underscore the potential value of adjuvant chemotherapy and highlight the importance of treatment completion in managing T4 colon cancer. Conclusions: Our study identifies LVI and adjuvant chemotherapy as key prognostic factors in T4 colon cancer patients. These results support the consideration of adjuvant chemotherapy in this patient population. [ABSTRACT FROM AUTHOR]

Deep brain stimulation (DBS) is an advanced treatment in Parkinson's disease. We describe a 71-year-old patient in whom the DBS got infected with Mycobacterium bovis shortly after intravesical BCG instillations as an adjuvant treatment of bladder cancer. The DBS internal pulse generator and extension wires had to be replaced, and the patient was treated successfully with rifampicin, isoniazid, and ethambutol during three months. This case suggests that physicians need to be aware of the risk of this kind of infection and add a specific Mycobacterial test to the regular cultures. [ABSTRACT FROM AUTHOR]

Background: Australia's National Bowel Cancer Screening Program consists of an immunohistochemical faecal occult blood test, targeting adults aged 50–74. Existing literature supports the principle of early detection of colorectal cancer (CRC) via national screening, but little is known about the association between colonoscopy or polypectomy rates and CRC stage over time. The aim of this study is to identify the longitudinal change to colonoscopy and polypectomy rates, and any stage shift associated with this screening program. Methods: A retrospective data‐linkage study was performed using the Australian national health database (Medicare) to obtain colonoscopy and polypectomy rates between 1998 and 2017. A second prospective database of CRC resection specimens was analysed for this period. The cohort was divided based on time intervals related to the National Bowel Cancer Screening Program: pre‐commencement 1998–2006 (Period A), immediately post‐commencement 2007–2011 (Period B), and subsequent years 2012–2017 (Period C). Linear regression was used to test relation between annualized predictor and response variables. Results: Annual colonoscopy rates doubled, and polypectomy rates tripled during the study (P < 0.001). Annual colonoscopy rate correlated to a lower T‐stage (P = 0.038) and lower N‐stage (P = 0.026), and there was a 7% increase in early CRC (stage I–II) in Period C (P < 0.001). Across the study period there was also a significant increase in right‐sided tumours, and concurrent MMR deficiency and BRAF mutation. Conclusion: Polypectomy and colonoscopy rates increased after the introduction of the National Bowel Cancer screening program. There was a clinically significant shift to earlier CRC stage which manifested 5 years after its implementation. [ABSTRACT FROM AUTHOR]

Simple Summary: The ability to predict or detect colorectal cancer (CRC) recurrence early after surgery enables physicians to apply appropriate treatment plans and different follow-up strategies to improve patient survival. A certain portion of CRCs will recur, and current surveillance tools have limitations in the precise and early detection of cancer relapse. Circulating tumor cells (CTCs), cancer cells that are disconnected from the primary tumor and enter the bloodstream, can provide real-time information on disease status. CTCs might become markers not only for predicting CRC recurrence but also for guiding therapy for stage II CRC and monitoring disease relapse in locally advanced rectal cancer patients receiving neoadjuvant therapy. Using CTC subtypes and CTCs combined with clinicopathological factors is an even more powerful way to predict CRC recurrence. The ability to predict or detect colorectal cancer (CRC) recurrence early after surgery enables physicians to apply appropriate treatment plans and different follow-up strategies to improve patient survival. Overall, 30–50% of CRC patients experience cancer recurrence after radical surgery, but current surveillance tools have limitations in the precise and early detection of cancer recurrence. Circulating tumor cells (CTCs) are cancer cells that detach from the primary tumor and enter the bloodstream. These can provide real-time information on disease status. CTCs might become novel markers for predicting CRC recurrence and, more importantly, for making decisions about additional adjuvant chemotherapy. In this review, the clinical application of CTCs as a therapeutic marker for stage II CRC is described. It then discusses the utility of CTCs for monitoring cancer recurrence in advanced rectal cancer patients who undergo neoadjuvant chemoradiotherapy. Finally, it discusses the roles of CTC subtypes and CTCs combined with clinicopathological factors in establishing a multimarker model for predicting CRC recurrence. [ABSTRACT FROM AUTHOR]

• Molecular classification has changed the adjuvant treatment of endometrial cancer. • Low-middle income countries face barriers to fully implementing molecular classification. • Although not ideal as the only marker, p53 immunohistochemistry could play a role in the decision-making process of delineating adjuvant treatment. Endometrial cancer (EC) treatment changed substantially with the introduction of molecular classification. Low-middle income (LMIC) countries will face barriers to including molecular classification to guide treatment. This study aims to analyse the value of p53 immunohistochemistry to delineate adjuvant treatment in FIGO stages I and II. Patients with EC treated between 2010 and 2016 were retrospectively evaluated. Patients included in this analysis must have reviewed FIGO stage I/II high-grade histologies (endometrioid grade 3, serous, clear cell, carcinosarcoma, mixed and undifferentiated). Samples were subjected to p53 immunohistochemistry. Recurrence-free and overall survival were analysed using the Kaplan-Meier method and log-rank test. Cox proportional hazards regression was performed for multivariable analysis. From 2010 to 2016, 265 patients met the inclusion criteria. Patients with aberrant p53 (71.4 %) were associated with older age (59.7 % vs 77.8 % with more than 60 years), relapse (12.5 vs 29.6 %) and death (22.2 vs 46.7 %). The pattern of relapse was not different, with most being at extrapelvic sites (55.5 % vs 62.3 % for p53 wild type and aberrant, respectively). The median overall survival was not reached versus 92.2 months for p53 wild type and aberrant, respectively (p = 0.003). In multivariate analysis, chemotherapy decreased death (p = 0.014) in p53 aberrant tumours, a benefit not seen in the wild-type cohort (p = 0.22). This retrospective analysis corroborates the finding of worse outcomes for p53 aberrant tumours in stage I/II EC and the benefit of more aggressive adjuvant treatment (systemic therapy and radiotherapy). Although not ideal as a sole molecular marker, p53 immunohistochemistry could complement the classical anatomopathological features and be part of the decision-making process with patients in LMIC.

Malignant tumors are complex systemic chronic diseases and one of the major causes of human mortality. Targeted therapy, chemotherapy, immunotherapy, and radiotherapy are examples of mainstream allopathic medicine treatments that effective for intermediate and advanced malignant tumors. The ongoing use of conventional allopathic medicine has resulted in adverse responses and drug resistance, which have hampered its efficacy. As an important component of complementary and alternative medicine, Chinese medicine has been found to have antitumor effects and has played an important role in enhancing the therapeutic sensitivity of mainstream allopathic medicine, reducing the incidence of adverse events and improving immune-related functions. The combined application of adjuvant Chinese medicine and mainstream allopathic medicine has begun to gain acceptance and is gradually used in the field of antitumor therapy. Traditional natural medicines and their active ingredients, as well as Chinese patent medicines, have been proven to have excellent therapeutic efficacy and good safety in the treatment of variousmalignant tumors. This paper focuses on the mechanism of action and research progress of combining the above drugs with mainstream allopathic medicine to increase therapeutic sensitivity, alleviate drug resistance, reduce adverse reactions, and improve the body's immune function. To encourage the clinical development and use of Chinese herb adjuvant therapy as well as to provide ideas and information for creating safer and more effective anticancer medication combinations, the significant functions of Chinese herb therapies as adjuvant therapies for cancer treatment are described in detail.

We herein report 3 cases of breast cancer who developed Pneumocystis Jirovecii Pneumonia during dose-dense chemotherapy. The patients developed fever, fatigue, and cough on the 4th to 5th cycle of chemotherapy. Chest computed tomography (CT) scan showed ground-glass opacities, later on confirmed PCP as bronchoalveolar lavage (BAL) was performed. They were treated with Trimethoprim-Sulfamethoxazole (TMP-SMX) for 3 weeks, with clinical improvement. The first case was able to complete subsequent cycles of chemotherapy with TMP-SMX prophylaxis. The second case omitted the remaining cycles of chemotherapy and proceeded with adjuvant hormonal and radiotherapy. The third case also discontinued subsequent cycles and proceeded with surgery. All 3 cases didn't developed complications nor recurrence of infection on their subsequent treatments. Clinicians must be vigilant in recognizing those at risk for PCP especially among cancer patients undergoing dose-dense chemotherapy. Moreover, as the infection is life-threatening, early treatment must be initiated to prevent serious complications. Prophylactic antibiotic must be considered if there is a high-risk for recurrence of infection, thus preventing delay in surgery or adjuvant therapies. [ABSTRACT FROM AUTHOR]

Tamoxifen is part of the standard of care of endocrine therapy for adjuvant treatment of breast cancer. However, survival outcomes with tamoxifen are highly variable. The concentration of endoxifen, the 30–100 times more potent metabolite of tamoxifen and bioactivated by the CYP2D6 enzyme, has been described as the most relevant metabolite of tamoxifen metabolism. A genome‐wide association study (GWAS) was performed with the objective to identify genetic polymorphisms associated with endoxifen serum concentration levels and clinical outcome in early‐stage breast cancer patients receiving tamoxifen. A GWAS was conducted in 608 women of the CYPTAM study (NTR1509/PMID: 30120701). Germline DNA and clinical and survival characteristics were readily available. Genotyping was performed on Infinium Global Screening Array (686,082 markers) and single nucleotide polymorphism (SNP) imputation by using 1000 Genomes. Relapse‐free survival during tamoxifen (RFSt) was defined the primary clinical outcome. Endoxifen serum concentration was analyzed as a continuous variable. Several genetic variants reached genome‐wide significance (P value: ≤5 × 10−8). Endoxifen concentrations analysis identified 430 variants, located in TCF20 and WBP2NL genes (chromosome 22), which are in strong linkage disequilibrium with CYP2D6 variants. In the RFSt analysis, several SNP were identified (LPP gene: rs77693286, HR 18.3, 95% CI: 15.2–21.1; rs6790761, OR 18.2, 95% CI: 15.5–21.1). Endoxifen concentrations have a strong association with the chromosome 22, which contains the CYP2D6 gene. [ABSTRACT FROM AUTHOR]

Objective: The efficacy and safety of different doses of PEG recombinant human granulocyte colony-stimulating factor (PEG-rhG-CSF) in the prevention of leukopenia/neutropenia during concurrent chemoradiotherapy for cervical cancer were investigated. Methods: The patients who received concurrent radiotherapy and chemotherapy for cervical cancer from June 2020 to January 2023 were selected to evaluate the difference in efficacy, adverse reactions, and treatment cost of PEG-rhG-CSF in the prevention of leukopenia/neutropenia between the test group and the control group. Results: The minimum value of leukopenia/neutropenia in the test group was significantly higher than that in the control group (P < 0.05). The incidence of grade ≥ 3 leukopenia/neutropenia was significantly lower than that of the control group (P < 0.05). The number of interrupted days of radiotherapy was less than that of the control group (P < 0.05). PEG-rhG-CSF of different prophylactic doses (100 μg/kg dose or 50 μg/kg dose) had similar prophylactic effects in the test group, OR=1.192 (0.761, 1.868), P=0.443. Conclusion: Prophylactic application of PEG-rhG-CSF could reduce the incidence of leukopenia/neutropenia in cervical cancer during concurrent chemoradiotherapy. There was no significant difference in efficacy and safety with prophylactic use of drug at doses of 100 μg/kg and 50 μg/kg. [ABSTRACT FROM AUTHOR]

Objective: To estimate the incidence and report the details of hystological, clinical, surgical, and demographic features of incidental uterine sarcomas in patients operated with symptomatic myoma uteri. Material and Methods: We designed a retrospective cohort study at Adnan Menderes University Gynecologic Oncology Department that includes totally 896 patients with symptomatic myoma uteri who were operated as a hysterectomy or myomectomy. Following the definition of inclusion and exlusion criterias, incidental uterine sarcoma cases were detailed as histological subtype, tumor diameter, morcellation or fragmentation status in surgery, adjuvant treatment, recurrences, and survival. All cases were reported as a table without specific statistical analyzes. Results: A total of 775 hysterectomy and 121 myomectomy cases were analyzed. Fourteen sarcoma cases were reported. Two sarcoma cases were excluded due to adnexal sarcoma in final pathology. Ten cases were reported in final pathology incidentally. 7/10 cases were reported as leiomyosarcoma while low grade endometrial stromal sarcoma were reported in 2 cases. While all recurrences were seen in leiomyosarcoma group (5 cases), two of them died with disease-related complications. Conclusion: Studies have shown that uterine sarcomas are malignancies that are extremely rare and cannot be predicted preoperatively. Due to its low incidence and uncertain tumor behavior, in low-risk patients, myomectomy with mechanical or power morcellation is a safe surgical option when it is perfomed without abdominal spillage which can be common in laparoscopic surgery.

Temporal bone squamous cell carcinoma (TBSCC) is a rare and invasive malignant tumor. The common predisposing factors include a history of local radiotherapy and chronic suppurative otitis media. The current treatment approach for TBSCC primarily involves surgery, followed by adjuvant radiotherapy and chemotherapy, based on T staging and high‐risk factors. Although patients with early‐stage TBSCC have a high survival rate after treatment, the majority of patients are diagnosed in the intermediate to advanced stages, with extensive tumor involvement, posing challenges for surgical intervention. Definitive chemoradiotherapy (CRT) serves as a viable alternative for unresectable tumors. Constraints in administering curative radiation doses, due to the tolerance of surrounding organs, can lead to uncontrolled tumor growth. Although programmed cell death 1 inhibitors have demonstrated efficacy in head and neck squamous cell carcinoma and cutaneous squamous cell carcinoma, their application in TBSCC remains underexplored. Herein, we report a case of a 47‐year‐old man diagnosed with unresectable advanced and localized TBSCC. Following inadequate tumor control with primary chemoradiotherapy, immunotherapy was initiated, resulting in disease remission within a follow‐up period of > 4 years. [ABSTRACT FROM AUTHOR]

Vitamin D3 or calcitriol (VitD3) has been shown to have anticancer and anti-inflammatory activity in in vitro models and clinical studies. However, its effect on HPV-16-related cancer has been sparsely explored. In this study, we aimed to determine whether monotherapy or combination therapy with cisplatin (CP) reduces tumor growth and affects survival and systemic inflammation. Treatments were administered to C57BL/6 mice with HPV-16-related tumors (TC-1 cells) as follows: (1) placebo (100 µL vehicle, olive oil, orally administered daily); (2) VitD3 (3.75 µg/kg calcitriol orally administered daily); (3) CP (5 mg/kg intraperitoneally, every 7 days); and (4) VitD3+CP. Tumor growth was monitored for 25 days, survival for 60 days, and the neutrophil-to-lymphocyte ratio (NLR) was evaluated on days 1 (baseline), 7, and 14. VitD3+CP showed greater success in reducing tumor volume compared to CP monotherapy (p = 0.041), while no differences were observed between CP and VitD3 monotherapy (p = 0.671). Furthermore, VitD3+CP prolonged survival compared to CP (p = 0.036) and VitD3 (p = 0.007). Additionally, at day 14 the VitD3 and VitD3+CP groups showed significantly lower NLR values than the CP group (p < 0.05, for both comparisons). Vitamin D3 could be a promising adjuvant in the treatment of cervical cancer or solid tumors and deserves further investigation. [ABSTRACT FROM AUTHOR]

Background: Primary intracranial Ewing's sarcoma (ES) is a type of primitive neuroectodermal tumour and is a rare malignant tumour in children and adolescents. The imaging features of ES overlap with other central nervous system embryonal tumours, making it difficult to pinpoint a specific diagnosis. We aim to explore the clinical, neuroimaging and differential diagnoses of this entity. Case presentation: We describe a 6-month-old infant who presented with complaints of enlarging the head size and poor feeding. Imaging revealed a contrast-enhancing large solid-cystic mass lesion with internal calcification, focal bone erosion and haemorrhage in the posterior fossa. Histopathological examinations, immunohistochemistry, and molecular analysis confirmed ES. Conclusions: The confirmative diagnosis of primary intracranial ES requires histological examination, immunohistochemical analysis, and genetic detection, along with radiological findings. Surgical excision followed by combined radiotherapy and chemotherapy is the treatment of choice. [ABSTRACT FROM AUTHOR]

Key Points: Question: Does aspirin at 300 mg/d improve invasive disease–free survival among survivors of nonmetastatic breast cancer? Findings: This randomized, placebo-controlled clinical trial included 3020 patients with high-risk nonmetastatic breast cancer. The trial was terminated early because of lack of benefit from aspirin (hazard ratio for invasive disease–free survival for aspirin vs placebo, 1.27 [not statistically significant]). Meaning: There was no benefit of aspirin at 300 mg/d on breast cancer recurrence and survival. Importance: Observational studies of survivors of breast cancer and prospective trials of aspirin for cardiovascular disease suggest improved breast cancer survival among aspirin users, but prospective studies of aspirin to prevent breast cancer recurrence are lacking. Objective: To determine whether aspirin decreases the risk of invasive cancer events among survivors of breast cancer. Design, Setting, and Participants: A011502, a phase 3, randomized, placebo-controlled, double-blind trial conducted in the United States and Canada with 3020 participants who had high-risk nonmetastatic breast cancer, enrolled participants from 534 sites from January 6, 2017, through December 4, 2020, with follow-up to March 4, 2023. Interventions: Participants were randomized (stratified for hormone receptor status [positive vs negative], body mass index [≤30 vs >30], stage II vs III, and time since diagnosis [<18 vs ≥18 months]) to receive 300 mg of aspirin (n = 1510) or placebo once daily (n = 1510) for 5 years. Main Outcomes and Measures: The primary outcome was invasive disease–free survival. Overall survival was a key secondary outcome. Results: A total of 3020 participants were randomized when the data and safety monitoring committee recommended suspending the study at the first interim analysis because the hazard ratio had crossed the prespecified futility bound. By median follow-up of 33.8 months (range, 0.1-72.6 months), 253 invasive disease–free survival events were observed (141 in the aspirin group and 112 in the placebo group), yielding a hazard ratio of 1.27 (95% CI, 0.99-1.63; P =.06). All invasive disease–free survival events, including death, invasive progression (both distant and locoregional), and new primary events, were numerically higher in the aspirin group, although the differences were not statistically significant. There was no difference in overall survival (hazard ratio, 1.19; 95% CI, 0.82-1.72). Rates of grades 3 and 4 adverse events were similar in both groups. Conclusion and Relevance: Among participants with high-risk nonmetastatic breast cancer, daily aspirin therapy did not improve risk of breast cancer recurrence or survival in early follow-up. Despite its promise and wide availability, aspirin should not be recommended as an adjuvant breast cancer treatment. Trial Registration: ClinicalTrials.gov Identifier: NCT02927249 This study examines the potential benefits of aspirin as adjuvant therapy for survivors of early breast cancer. [ABSTRACT FROM AUTHOR]

Simple Summary: In soft tissue sarcomas, unplanned resections, so-called Whoops procedures, do occur frequently. Whether re-resection reduces local recurrence or improves overall survival is unclear. 185 patients who underwent unplanned resection were included. Group A (n = 156) underwent re-excision, while Group B (n = 29) not. Residual tumor was observed in 60% of the resected tumors. In Group A, 8% of the patients developed local recurrence, in Group B 14% (n.s.). Overall survival and local recurrence-free survival were not different between the groups. However, within the subgroup of patients with residual disease in the re-resected specimen, survival was compromised, and the local recurrence rate was higher. Particularly for low-grade lesions, more patients could be treated without re-resections. Background: In soft tissue sarcomas, unplanned resections, or so-called Whoops procedures, do occur quite frequently, thus primarily owing to the abundant presence of benign lesions. Whether re-resection reduces local recurrence or improves overall survival remains a topic of ongoing debate. The principle objective of this study was to analyze the outcomes of patients with soft tissue sarcomas of the extremities or trunk wall after an incidental marginal resection by comparing re-resections to individuals who declined the procedure. Methods: A total of 185 patients who underwent unplanned resection were included. These patients were stratified into two groups: Group A (n = 156) underwent re-excision, while Group B (n = 29) was treated conservatively. Depending on the clinical scenario, radio- or chemotherapy was either administered in a neoadjuvant or an adjuvant setting. The presence of residual tumor and metastatic disease was documented. Clinical outcomes, specifically local recurrence (LR), local recurrence-free survival (LRFS) and overall survival (OS), were utilized for evaluation. Results: Group B exhibited significantly larger tumors (p < 0.0001) and a higher mean age than Group A. Among the patients in Group A, 11 (5.9%) had contaminated resection margins (R1), and residual disease (RD) was observed in 93 (59.6%) of the resected specimens. In group B, 10 patients received adjuvant radiotherapy alone, 5 received chemotherapy alone, and 13 underwent a combined approach consisting of both radio- and chemotherapy. In Group A, 8% (n = 12) of the patients developed local recurrence (LR) during the observation period. Conversely, in Group B, this amount was 14% (n = 4) (n.s.). Of the 12 LR in Group A, 10 were found in the subgroup with residual disease. Overall survival and local recurrence-free survival were not significantly different between the groups. A total of 15% (n = 24) of the patients in Group A developed metastatic disease, while 10% (n = 3) in Group B developed metastatic disease (n.s.). Conclusions: Following the reresection of unplanned resected STS, there was no statistically significant difference observed in overall survival or LR compared to patients who did not undergo re-resection. However, within the subgroup of patients with residual disease in the re-resected specimen, the OS was compromised, and the LR rate was higher. Particularly for low-grade lesions, adopting a more conservative approach seems to be justified. [ABSTRACT FROM AUTHOR]

Chemotherapeutic drugs are indispensable in cancer treatment, but their effectiveness is often lessened because of non-selective toxicity to healthy tissues, which triggers inflammatory pathways that are harmful to vital organs. In addition, tumors' resistance to drugs causes failures in treatment. Chlorogenic acid (5-caffeoylquinic acid, CGA), found in plants and vegetables, is promising in anticancer mechanisms. In vitro and animal studies have indicated that CGA can overcome resistance to conventional chemotherapeutics and alleviate chemotherapy-induced toxicity by scavenging free radicals effectively. This review is a summary of current information about CGA, including its natural sources, biosynthesis, metabolism, toxicology, role in combatting chemoresistance, and protective effects against chemotherapy-induced toxicity. It also emphasizes the potential of CGA as a pharmacological adjuvant in cancer treatment with drugs such as 5-fluorouracil, cisplatin, oxaliplatin, doxorubicin, regorafenib, and radiotherapy. By analyzing more than 140 papers from PubMed, Google Scholar, and SciFinder, we hope to find the therapeutic potential of CGA in improving cancer therapy. [ABSTRACT FROM AUTHOR]

Human papillomavirus (HPV)-related oropharyngeal squamous cell carcinoma (OPSCC) presents unique challenges and opportunities for treatment, particularly regarding de-escalation strategies to reduce treatment morbidity without compromising oncological outcomes. This paper examines the role of Transoral Robotic Surgery (TORS) as a de-escalation strategy in managing HPV-related OPSCC. We conducted a comprehensive literature review from January 2010 to June 2023, focusing on studies exploring TORS outcomes in patients with HPV-positive OPSCC. These findings highlight TORS's potential to reduce the need for adjuvant therapy, thereby minimizing treatment-related side effects while maintaining high rates of oncological control. TORS offers advantages such as precise tumor resection and the ability to obtain accurate pathological staging, which can guide the tailoring of adjuvant treatments. Some clinical trials provide evidence supporting the use of TORS in specific patient populations. The MC1273 trial demonstrated promising outcomes with lower doses of adjuvant radiotherapy (RT) following TORS, showing high locoregional tumor control rates and favorable survival outcomes with minimal side effects. ECOG 3311 evaluated upfront TORS followed by histopathologically directed adjuvant therapy, revealing good oncological and functional outcomes, particularly in intermediate-risk patients. The SIRS trial emphasized the benefits of upfront surgery with neck dissection followed by de-escalated RT in patients with favorable survival and excellent functional outcomes. At the same time, the PATHOS trial examined the impact of risk-adapted adjuvant treatment on functional outcomes and survival. The ongoing ADEPT trial investigates reduced-dose adjuvant RT, and the DART-HPV study aims to compare standard adjuvant chemoradiotherapy (CRT) with a reduced dose of adjuvant RT in HPV-positive OPSCC patients. These trials collectively underscore the potential of TORS in facilitating treatment de-escalation while maintaining favorable oncological and functional outcomes in selected patients with HPV-related OPSCC. The aim of this scoping review is to discuss the challenges of risk stratification, the importance of HPV status determination, and the implications of smoking on treatment outcomes. It also explores the evolving criteria for adjuvant therapy following TORS, focusing on reducing radiation dosage and volume without compromising treatment efficacy. In conclusion, TORS emerges as a viable upfront treatment option for carefully selected patients with HPV-positive OPSCC, offering a pathway toward treatment de-escalation. However, selecting the optimal candidate for TORS-based de-escalation strategies is crucial to fully leverage the benefits of treatment de-intensification. [ABSTRACT FROM AUTHOR]

Esophageal carcinoma (EC) and nutritional status are strongly linked due to swallowing disruptions and treatment-related toxicities. Therefore, malnutrition and weight loss (WL) occur in 85% and 79% of EC patients, respectively. WL is frequently associated with worse EC patient outcomes, however, WL during radiation therapy (RT) and EC patient outcomes have not been well established. The purpose of this study is to retrospectively review the association of WL during RT treatment of EC with clinical outcomes. Non-metastatic EC patients from our institution treated between 2010 and 2018, receiving total prescribed dose >40 Gy and aged >18 years, were included. Patients were analyzed by WL during RT, with categories of ≥5% vs. <5% and ≥10% vs. <10%. Patient characteristics and treatment regimens were similar across all WL groups. In univariate analysis, ≥5% and ≥10% WL were significantly associated with both worse overall survival (OS) and progression-free survival (PFS), and ≥10% WL was significantly associated with increased local recurrence. In multivariate analysis, ≥5% WL was significantly associated with OS and PFS. With both ≥5% and ≥10% WL throughout the radiation treatment being detrimental to OS and PFS. The importance of nutritional support in EC patients receiving radiotherapy is further validated. [ABSTRACT FROM AUTHOR]

Background: Breast cancer is a major public health problem. Covid-19 pandemic impacted all areas of daily life, including medical care. In particular, delivering care for patients with cancer or suspected cancer during the crisis was challenging given the competing risks of death from untreated cancer versus serious complications from SARS-CoV-2, and the likely higher lethality of Covid-19 in immunocompromised patients. This study aims to assess the efficacy and immunogenicity of SARS-COV-2 vaccines in breast cancer patients by evaluating antispike antibodies in vaccinated and non-vaccinated patients and also through assessing the infection with Covid-19 after vaccination in vaccinated patients and non-vaccinated patients. The study also aims to assess the safety of SARSCOV-2 vaccine in breast cancer patients (local and systemic toxicity). Methods: Our population consisted of 120 female patients diagnosed with early and locally advanced breast cancer (60 vaccinated and 60 unvaccinated against Covid-19), in the breast cancer unit, clinical oncology department, Ain Shams University Hospitals. All were on oncological systemic therapy (neoadjuvant or adjuvant treatment). The cutoff value of SARS COV-2 antibody is 50 AU/mL (= 50 seropositive, <50 seronegative). Results: Out of 120 patients, anti-SARS COV-2 antibody seropositivity was found to be 48 in non-vaccinated vs.58 in vaccinated patients (80% vs.96.7%), with p-value =0.0046, which was statistically significant. The median titre in both groups was found to be 1434.5 vs.2500, (p=0.0026). In the 120 patients, 26 patients had Covid-19 infection with a significant difference (p= 0.0004), with 21 (35%) non-vaccinated vs.5 (8.3 %) vaccinated. In the sixty vaccinated patients, mild local adverse events were reported such as warmness at site of injection in 17 (28.3%) patients, pain (11, 18.3%), swelling (11, 18.3%), itching (8, 13.3%), and redness (6, 10%) representing the least adverse event. The patients experienced mild systemic adverse events, the highest incidence was fatigue (28, 46.7%), then myalgia/arthralgia (17, 28.3%), headache (2, 3.3%), and fever (16, 26.7%). There was no statistical significance association between antispike Ab titre and age, stage, treatment types, and time since last vaccine. Conclusion: SARSCOV-2 vaccines are effective and safe in localized breast cancer patients on systemic therapy. [ABSTRACT FROM AUTHOR]

Aromatase inhibitors (AIs) have shown great success as adjuvant therapy for post-menopausal women with hormone receptor–positive breast cancers. AI-induced arthralgia (AIA) is a frequent AI toxicity contributing to non-adherence and discontinuation. This review aims to understand current knowledge of AIA. The mean incidence of AIA was 39.1% and the mean discontinuation of AI therapy due to AIA was 9.3%. Most of the AIAs were non-inflammatory. A shorter time since the last menstrual period and pre-existing joint pain were risk factors. Vitamin D3 supplementation may be a preventative measure and treatment with duloxetine, acupuncture and/or exercise is supported by large randomized controlled trials. There was consistent improvement in AIAs with switching to an alternate AI, and this could additionally allow continuation of cancer treatment with AI. Further research is needed to identify predictive biomarkers, better characterize AIA subcategories and study more reliable therapeutic options. [ABSTRACT FROM AUTHOR]

OBJECTIVES: To elucidate prognostic factors, determine the best course of treatment methods, and assess oncological results in individuals diagnosed with uterine sarcoma. STUDY DESIGN: Between January 2001 and August 2023, 30 patients with uterine sarcomas (US) were included and analyzed in this cross-sectional study. Sixteen patients (53.3%) had uterine leiomyosarcoma, 6 patients (20%) had high-grade endometrial stromal sarcoma, 8 patients (26.7%) had low-grade endometrial stromal sarcoma. RESULTS: The median follow-up of all participants was 50 months. Recurrence was detected in 43.3% of the patients. 5-year survival ratio was 73.3%, 5-year disease-free survival ratio was 66.7%, the overall survival ratio was 70% and the overall disease-free survival rate was 56.6%. No difference was observed between groups in terms of survival comparisons. No statistically significant effect of adjuvant systemic chemotherapy, adjuvant radiotherapy, and combined treatments on median overall survival and median disease-free survival was detected (p>0.05). CONCLUSION: Uterine sarcomas are uncommon malignancies characterized by a poor prognosis, even in early stages, and they are associated with a high recurrence ratio. The most effective treatment method remains unclear to date. [ABSTRACT FROM AUTHOR]

Background: We investigated the impact of the prognostic nutritional index (PNI) on esophageal cancer survival and recurrence after curative treatment. Methods: This study included 120 patients who underwent curative surgery followed by the adjuvant treatment for esophageal cancer between 2008 and 2018. The risk factors for overall survival (OS) and recurrence-free survival (RFS) were identified. Results: The PNI of 49 was regarded to be the optimal critical point of classification considering the 1-year, 3-year, and 5-year survival rate. The OS rates at three and five years after surgery were 47.4% and 36.0% in the PNI low group, respectively, and 62.5% and 56.5% in the PNI high group, which amounted to a statistically significant difference (P = 0.020). The RFS rates at three and five years after surgery were 31.0% and 24.8% in the PNI low group, respectively, and 50.9% and 42.8% in the PNI high group, which amounted to a statistically significant difference (P = 0.020). A multivariate analysis demonstrated that the PNI was a significant independent risk factor for the OS and a marginally significant independent risk factor forRFS. Conclusion: The PNI was a risk factor for survival in patients who underwent curative treatment for esophageal cancer. It is necessary to develop the effective plan of the perioperative care and the surgical strategy according to the PNI. [ABSTRACT FROM AUTHOR]

Oral cancers comprise 50% of all head and neck malignancies in India which can be attributed to tobacco chewing. Advanced oral cancers are managed with surgery followed by adjuvant radiotherapy or adjuvant chemoradiation. There is paucity of studies regarding need for adjuvant treatment in oral cancers with close margins i.e. ≤ 0.5 cm after formalin fixation. This study aims at documenting the oncological outcome with regards to loco-regional control, disease-free survival, overall survival and complications of adjuvant radiotherapy and adjuvant chemoradiation in operated oral cancer patients having close margins of resection. In this Retrospective cohort study, 163 patients with stage T1–T4 oral cancers operated between 2015 and 2019 who have fulfilled the inclusion and exclusion criteria, received adjuvant treatment and could be followed up for at least one year were included. At the end of 45 months, the overall survival was 74.7% and disease specific survival was 82.7%. Among the 7 patients who defaulted radiotherapy, 4 patients succumbed to the disease. Complications were bone marrow depression (2 patients), dysphagia (17) and Trismus (1). Adjuvant radiotherapy should be given in oral cancer patients with close margins of resection since it improves the oncological outcome and disease specific survival and the benefit often outweighs the risk.

Simple Summary: In recent years, targeted therapy has significantly improved the lives of patients suffering from spine metastasis. However, traditional scoring systems used to predict treatment outcomes may not reflect these advancements. This study aims to explore the latest literature on medical therapy options for metastatic spinal tumors, particularly focusing on targeted therapy compared to other treatments. Through a systematic review and data analysis, this research highlights the effectiveness of targeted therapy, especially in lung and breast cancers, in prolonging the median overall survival. By considering the recent advances in medical oncology, these findings emphasize the importance of incorporating personalized treatment approaches into the management of metastatic spine tumors. This study provides valuable insights for clinicians and researchers in optimizing treatment strategies for patients with spinal metastases. Targeted therapy has greatly improved the outlook for patients with spinal metastatic cancers. Scoring systems like the Tokuhashi or Tomita scores are commonly used to predict prognosis and inform surgical decisions, but they are outdated and fail to consider recent advancements. We aimed to investigate the current state of the literature and treatment options pertaining to advancements in targeted therapy compared to other forms of medical management for metastatic spinal tumors. This study represents the first comprehensive systematic review that encompasses the most common primary cancers that metastasize to the spine and evaluates the median overall survival (mOS) across five different medical treatment modalities as well as surgical intervention. Additionally, our study analyzes the tumor receptor status in conjunction with these treatments. A PubMed search was conducted, and according to the PRISMA guidelines, 28 articles out of 1834 met the inclusion criteria. The pooled data analysis highlighted the superior efficacy of targeted therapy, evidenced by a significant improvement in the mOS and lower hazard ratios in patients with lung and breast cancers who received targeted therapy compared to those who did not. Our study provides valuable insights into the recent advancements in the medical management of metastatic spinal tumors. Future indications include incorporating this literature into personalized treatment approaches for metastatic spinal tumors. [ABSTRACT FROM AUTHOR]

Simple Summary: Recently, significant breakthroughs have been made in the medical treatment of advanced hepatocellular carcinoma (HCC). There is no consensus on whether adjuvant therapy is necessary after curative surgery for HCC. However, some patients still face a high risk of recurrence. Consequently, researchers have been exploring adjuvant therapies, such as chemotherapy, targeted therapy, and immunotherapy, to mitigate the risk of recurrence and improve patient prognosis. Although there is ongoing debate regarding the necessity of adjuvant therapy after surgery, examining the literature and investigating risk factors for high recurrence and the efficacy of current treatments can provide clinicians with more comprehensive information to develop individualized treatment plans. Moreover, advancements in future research and clinical practice will enhance our understanding and treatment of high recurrence in HCC. Hepatocellular carcinoma (HCC) stands as the most prevalent form of primary liver cancer and is highly invasive and easily recurs. For HCC, chemotherapy shows limited effect. The gold standard for HCC treatment includes curative surgical resection or liver transplantation. However, the recurrence rate at 5 years after liver resection is estimated at approximately 70% and even at 5 years after liver transplantation, it is 20%. Therefore, improving survival outcomes after curative surgical resection of liver cancer is crucial. This review highlights the importance of identifying risk factors for HCC recurrence following radical surgical resection and adjuvant therapy options that may reduce the recurrence risk and improve overall survival, including local adjuvant therapy (e.g., transcatheter arterial chemoembolization and radiotherapy), adjuvant systemic therapy (e.g., small molecule targeted therapy and immunotherapy), and other adjuvant therapies (e.g., chemotherapy). However, further research is needed to refine the use of these therapies and optimize their effectiveness in preventing HCC recurrence. [ABSTRACT FROM AUTHOR]

Cancer and chemotherapy induce a severe loss of muscle mass (known as cachexia), which negatively impact cancer treatment and patient survival. The aim of the present study was to investigate whether cannabidiol (CBD) administration may potentially antagonize the effects of cisplatin in inducing muscle atrophy, using a model of myotubes in culture. Cisplatin treatment resulted in a reduction of myotube diameter (15.7 ± 0.3 vs. 22.2 ± 0.5 µm, P < 0.01) that was restored to control level with 5 µM CBD (20.1 ± 0.4 µM, P < 0.01). Protein homeostasis was severely altered with a ≈70% reduction in protein synthesis (P < 0.01) and a twofold increase in proteolysis (P < 0.05) in response to cisplatin. Both parameters were dose dependently restored by CBD cotreatment. Cisplatin treatment was associated with increased thiobarbituric acid reactive substances (TBARS) content (0.21 ± 0.03 to 0.48 ± 0.03 nmol/mg prot, P < 0.05), catalase activity (0.24 ± 0.01 vs. 0.13 ± 0.02 nmol/min/µg prot, P < 0.01), whereas CBD cotreatment normalized TBARS content to control values (0.22 ± 0.01 nmol/mg prot, P < 0.01) and reduced catalase activity (0.17 ± 0.01 nmol/min/µg prot, P < 0.05). These changes were associated with increased mRNA expression of GPX1, SOD1, SOD2, and CAT mRNA expression in response to cisplatin (P < 0.01), which was corrected by CBD cotreatment (P < 0.05). Finally, cisplatin treatment increased the mitochondrial protein content of NDUFB8, UQCRC2, COX4, and VDAC1 (involved in mitochondrial respiration and apoptosis), and CBD cotreatment restored their expression to control values. Altogether, our results demonstrated that CBD antagonize the cisplatin-induced C2C12 myotube atrophy and could be used as an adjuvant in the treatment of cancer cachexia to help maintain muscle mass and improve patient quality of life. NEW & NOTEWORTHY: In an in vitro model, cisplatin treatment led to myotube atrophy associated with dysregulation of protein homeostasis and increased oxidative stress, resulting in increased apoptosis. Cotreatment with cannabidiol was able to prevent this phenotype by promoting protein homeostasis and reducing oxidative stress. [ABSTRACT FROM AUTHOR]

Objective: To determine the awareness and knowledge levels of osteoporosis in postmenopausal breast cancer survivors (PBCS) who have completed adjuvant chemoradiotherapy, are under hormonal therapy, or are being monitored, and to examine potentially related factors. Materials and Methods: Between March 2022 and December 2022, 73 breast cancer patients with clinically and biochemically proven menopause were included in the study. The demographic characteristics and clinical findings of the patients were recorded. The participants' osteoporosis knowledge level (OKL) regarding osteoporosis was evaluated with the osteoporosis knowledge test and their osteoporosis awareness level (OAL) was evaluated with the osteoporosis awareness test. P values <0.05 were considered statistically significant. Results: The mean age of the patients was 59.8±9.4 years (minimum-maximum: 32-75). Their OKL's were categorized as follows: 9.6% poor, 58.9% moderate and 31.5% good. Nutrition knowledge level (NKL) was distributed as follows: 9.6% poor, 37.3% moderate and 52.1% good. Exercise knowledge level (EKL) was distributed as follows: 13.7% poor, 31.5% moderate and 54.8% good. As the patient's age increased, it was observed that OAL, OKL, NKL and EKL decreased. A statistically significant correlation was found between higher education level and higher OAL (r=0.246, p=0.036). There was a significant inverse correlation between menopausal duration and OKL (r=-0,280, p=0.017). There was no significant difference in OAL, OKL, NKL and EKL between patients who received hormone therapy and those who did not. Conclusion: Our study, which assessed the awareness level of osteoporosis for the first time in PBCS, indicates the need for further research on the development of patient education programs for osteoporosis prevention and the improvement of methodological approaches specific to measuring awareness and knowledge levels in cancer patients.

Oxaliplatin-based chemotherapy protocols have improved survival in colorectal cancer as an adjuvant treatment. Nevertheless, sinusoidal obstruction syndrome (SOS) may occur during oxaliplatin therapy. Liver lesions related to sinusoidal obstruction syndrome can mimick liver metastasis. A 35-year-old female patient who has a history of right hemicolectomy due to colon adenocarcinoma 10 years ago, received 9 cycles of 500 mg capecitabine and 100 mg oxaliplatin as an adjuvant chemotherapy. Suspicious nodules were diagnosed at the liver during magnetic resonance imaging (MRI) which was performed 10 years after right hemicolectomy. Surgical intervention was performed. Focal nodular hyperplasia was diagnosed for all the liver lesions after pathological evaluation. Patients with colorectal cancer who received oxaliplatin based chemotherapy with the new onset liver lesions should be examined carefully. Not only radiological evaluation but also core needle biopsy should be used for misdiagnosis and preventing overtreatment. [ABSTRACT FROM AUTHOR]

Extrapulmonary small cell carcinoma (EPSCC) is very rare with an incidence of 0.1 to 0.4% in the United states and the exact incidence in other regions is unknown. Anal canal involvement is extremely rare contributing to < 1% of all EPSCC. Inspite of its rarity, it is of clinical importance due to its aggressive nature. Most of the patients present with lungs and liver metastasis at diagnosis even in early stage tumors. It has a dismal survival rate of 58% at 6-month and 6% at 5-years in contrast to squamous cell carcinoma of anal canal. Exact ethiopathogenesis is unknown. Association with HIV has been seen like squamous cell carcinoma of anal canal. There is very little literature evidence and management is not clear like that of squamous cell carcinoma anal canal. Here we present the case of a 63 year old HIV positive male who presented with small cell carcinoma of anal canal to our institute and the challenges we faced in diagnosis and management.
