Background: The most prevalent subtype of non-Hodgkin lymphoma is diffuse large B-cell lymphoma (DLBCL). Germinal center B-cell (GCB) and non-germinal center B-cell (non GCB) are the two main biologically different molecular subtypes identified utilizing an immunohistochemistry-based approach. Aim: Our objective in this study is to analyze the impact of immunohistochemical subtypes of DLBCL (GCB or non GCB) on demographic and clinicopathological parameters, response to chemotherapy and survival outcomes. Subjects and methods: This is a retrospective study including 106 cases of DLBCL collected in the department of pathology, Hassan II university hospital, Fez (Morocco), over a period of 12 years (January 2010-September 2022). The subtypes of DLBCLs were defined according to Hans algorithm, using immunohistochemistry by three biomarkers (CD10, BCL6, MUM1). Statistical analysis used: Independent t tests and analyses of variance were used for the comparison of mean values. We employed the SPSS 26.0 program to achieve this. A statistically significant value was set at P <.05. Results: Seventy-five patients (71%) were non-GCB subtype, while thirty-one patients (29%) had the GCB immunosubtype. We have found a significant (P <.05) correlations between DLBCL immunosubtypes and treatment responses on one hand and survival in the other hand. In the GCB subtype, the response rate and survival were significantly improved. A significant association was found between Ki 67 expression and survival on univariate analysis. On multivariate analysis, we note a correlation between Ki 67 expression, DLBCL immunohistochemical subtypes and survival outcome. Conclusion: Non GCB subtype is associated with poor response to treatment and inferior survival outcome compared to GCB subtype in Moroccan context, especially when combined with high expression of Ki 67 marker.

Background: Triple-negative breast cancer (TNBC) is characterized by a poor prognosis. Consequently, the current research aims to identify new therapeutic targets for TNBC patients. Trichorhinophalangeal syndrome type 1 (TRPS1), a novel GATA transcription factor, and CYP4Z1, a fatty acid hydroxylase, present potential targets for novel therapies. Method: This retrospective study included 70 TNBC patients. The immunohistochemical expression of TRPS1, GATA3, and CYP4Z1 was evaluated. Data regarding the patient's clinical and pathological responses to chemotherapy were collected and analyzed for response assessment. SPSS version 20 software facilitated the data analysis. Quantitative variables were described using means and standard deviations, whereas categorical variables were examined using the chi-square test or Fisher's exact test as appropriate. Survival analysis was performed using Kaplan-Meier plots, including disease-free and overall survival. A P-value of less than 0.05 was considered statistically significant. Results: The analysis showed that 37 cases (53%) were positive for TRPS1 expression, 45 cases (65%) for GATA3, and 40 cases (57%) for CYP4Z1. There was a significant association between the expression of GATA3, TRPS1, and CYP4Z1 and various prognostic factors such as tumor size, grade, stage, lymphovascular invasion, recurrence, and mortality. Notably, the overall recurrence and progression rates were significantly correlated with the overexpression of GATA3, TRPS1, and CYP4Z1. Conclusion: The overexpression of TRPS1, GATA3, and CYP4Z1 in TNBC patients may be novel prognostic factors for predicting tumor prognosis. Furthermore, these markers could assist in selecting patients for future therapies in both localized and metastatic breast carcinoma settings. [ABSTRACT FROM AUTHOR]

Simple Summary: This study assessed the prognostic impact of sarcopenic obesity (SO) in colorectal cancer patients. Among 211 sarcopenic patients, those with obesity (SO group) demonstrated significantly shorter cancer-related relapse-free survival (CRRFS) compared to their non-obese counterparts (non-SO group). While cancer-specific survival (CSS) was also poorer in the SO group, this difference did not reach statistical significance. Additionally, there was no significant difference in overall survival (OS) between the two groups. Multivariate analysis identified sarcopenic obesity, elevated CEA levels, and unfavorable histological types as independent predictors of poor CRRFS. These findings underscore the importance of routine assessment of both sarcopenia and obesity in clinical practice. Moreover, they highlight the potential benefits of interventions aimed at increasing muscle mass and reducing visceral fat to enhance patient outcomes. Background: Sarcopenia, the age-related loss of muscle mass, is a negative prognostic factor in gastrointestinal cancer. Sarcopenia combined with visceral obesity (sarcopenic obesity) is associated with poor outcomes. We explored the influence of obesity and other factors on the prognosis of patients with colorectal cancer diagnosed with sarcopenia. Methods: We enrolled 211 patients with colorectal cancer diagnosed with preoperative sarcopenic obesity who underwent radical resection at Osaka University Hospital between January 2009 and January 2012. Muscle mass was assessed using the psoas muscle mass index. Obesity was evaluated by measuring the visceral fat area in the umbilical region. Patients were categorized into two groups: sarcopenia with obesity (SO) and sarcopenia without obesity (non-SO). Overall survival, cancer-specific survival, and cancer-related relapse-free survival (CRRFS) were compared between the two groups. Patient characteristics, including age, sex, body mass index, serum albumin, C-reactive protein, tumor markers, prognostic nutritional index (PNI), modified Glasgow prognostic score (mGPS), and geriatric nutritional risk index (GNRI), were also analyzed. Results: CRRFS was significantly shorter in the SO group than in the non-SO group (p = 0.028). PNI, mGPS, and GNRI were not identified as significant prognostic factors for CRRFS. Multivariate analysis highlighted sarcopenic obesity, elevated carcinoembryonic antigen levels, and unfavorable histological types as significant predictors of poor CRRFS outcomes. Conclusions: Sarcopenic obesity is an independent predictor of poor prognosis in patients with CRC. Thus, interventions aimed at increasing muscle mass and reducing visceral fat could potentially improve the prognosis of these patients. [ABSTRACT FROM AUTHOR]

Simple Summary: In a retrospective study of 86 patients, we identified independent predictors of recurrence-free survival (RFS) and overall survival (OS) after the resection of liver metastases of uveal melanoma using a multivariable Cox model. A disease-free interval of ≤24 months and a chromosome 8q surgain were associated with worse survival. With these two parameters, we built a novel clinico-genetic score that defined three risk groups with distinct prognoses. This novel score identified patients with a high risk of relapse after surgery. These patients may benefit from neoadjuvant or adjuvant systemic therapy following complete surgical resection with the hope of improving survival outcomes. Surgical treatment of liver metastases of uveal melanoma (LMUM) could be proposed for selected patients. This retrospective study examined the prognostic significance of the genetic profiles of liver metastases after LMUM resection. A total of 86 patients treated with resection for LMUM, who underwent genetic analysis of liver metastasis, were included. A multivariable Cox model identified the independent predictors of recurrence-free survival (RFS) and overall survival (OS). The disease-free interval (DFI) and a chromosome 8q surgain (>3 copies) were independent predictors and categorized patients into three risk groups with distinct postoperative prognoses. For the low-, intermediate-, and high-risk scores of recurrence, the median RFS values were 15 months (95% CI: 10–22), 6 months (95% CI: 4–11), and 4 months (95% CI: 2–7), and the median OS values were 86 months (95% CI: 55-NR), 25 months (95% CI: 17–48), and 19 months (95% CI: 12–22), respectively. The predictive accuracy of this scoring system was demonstrated by a mean area under the curve (AUC(t)) of 0.77 (95% CI: 0.65–0.90) for RFS and 0.81 (95% CI: 0.70–0.92) for OS. This novel score, based on a DFI of ≤24 months combined with a chromosome 8q surgain, identifies patients at a high risk of early recurrence and could help clinicians to propose perioperative treatment.

Simple Summary: This research was conducted to evaluate the impact of ipilimumab treatment in patients with metastatic melanoma when monotherapy with PD-1 inhibitors has failed. In particular, the aim was to evaluate the efficacy of ipilimumab in this setting based on the presence or absence of BRAF or NRAS mutations. The present study could allow us to understand when salvage treatment with ipilimumab would have the best impact, although an analysis on a larger patient cohort would be necessary. Background: When monotherapy with PD-1 inhibitors in metastatic melanoma fails, there are currently no standard second-line choices. In case of the unavailability of clinical trials, ipilimumab represents a possible alternative treatment. Methods: We collected data of 44 patients who received ipilimumab after the failure of PD-1 inhibitors from July 2017 to May 2023 at our Institute. Overall survival (OS), progression-free survival (PFS), and post-progression survival (PPS) based on BRAF or NRAS mutation status, sex, and the presence of brain metastases were estimated using the Kaplan–Meier method. Cox regression was used to evaluate independence in multivariate analysis. The objective response rate (ORR) was estimated based on RECIST 1.1. Results: Among the 44 patients enrolled in this study, 28 BRAF-wildtype, 9 BRAF-mutated, and 7 NRAS-mutated patients were identified. OS analysis showed a significant difference between wildtype and BRAF- or NRAS-mutated patients: 23.2 months vs 5.3 and 4.59, respectively, p = 0.017. The presence of brain metastases and BRAF or NRAS mutation were independent factors for mortality in multivariate analysis. Conclusions: In case of failure to enroll patients in innovative clinical trials, second-line ipilimumab still represents an effective therapy in patients with metastatic wildtype melanoma and in the absence of brain metastases.

Simple Summary: In this study, we investigated whether the anatomical location of metastases from posterior uveal melanoma affects survival. We found that patients with newly diagnosed metastatic posterior uveal melanoma who only have extrahepatic metastases had a significantly longer survival compared to patients with liver metastases. This insight could help clinicians improve the prediction of patient outcomes and enhance the selection of patients in clinical trials. Background/Objectives: Metastatic posterior uveal melanoma (PUM) is one of the deadliest types of melanomas. Though the median survival is short, some patients with metastatic disease live for a long time. In this study, we investigated whether the anatomical location of the metastatic lesions is associated with differences in survival. Methods: One hundred and seventy-eight patients with metastatic PUM with baseline whole-body imaging were retrospectively included. The patients were divided into three groups based on the anatomical location of metastases: (1) exclusive liver metastases (hepatic pattern), (2) both hepatic and extrahepatic metastatic lesions (hepatic–extrahepatic pattern), and (3) exclusive extrahepatic lesions (extrahepatic pattern). Survival was investigated using Kaplan–Meier plots, log-rank test, and the Cox proportional hazard model. Results: In total, 95 patients (53%) presented with hepatic pattern, 66 patients (37%) presented with hepatic–extrahepatic pattern, and 17 patients (10%) presented with extrahepatic pattern. Overall survival was significantly longer in patients with extrahepatic pattern (median 17.0 months) compared to those with hepatic pattern (median 11.0 months) and hepatic–extrahepatic pattern (median 7.0 months) (p < 0.001, log-rank test). Multivariate Cox regression analysis showed increased hazard ratios (HR) for hepatic pattern (HR 2.37, 95% CI 1.08–5.17, p = 0.031) and hepatic–extrahepatic pattern (3.25, 95% CI 1.42–7.41, p = 0.005) compared to extrahepatic pattern. Most patients with hepatic (95%) and hepatic–extrahepatic patterns (82%) were diagnosed with metastases by liver ultrasonography screening, whereas 81% of patients with extrahepatic pattern developed symptoms that led to the diagnosis. Conclusions: Extrahepatic pattern was associated with prolonged survival in patients with metastatic PUM, despite there being a larger proportion of symptomatic patients. It is therefore important to consider the anatomical location of the metastatic lesions when stratifying patients into clinical trials. [ABSTRACT FROM AUTHOR]

Simple Summary: This study investigates racial disparities in the stage of gastric cancer at diagnosis and overall survival among different racial groups using data from the SEER database (2018–2021). The retrospective cohort study of 18,984 patients found that Hispanics are 19% more likely to be diagnosed at a later stage of gastric cancer compared to non-Hispanics. Additionally, both Hispanics and Black patients showed poorer overall survival compared to Non-Hispanic Whites. The disparities are attributed to factors such as healthcare access, insurance coverage, language barriers, and preventive health service utilization. These findings highlight the need for targeted interventions to address these disparities in cancer outcomes. Introduction: Racial disparities in gastric cancer outcomes, including stage at diagnosis and overall survival, continue to affect Hispanic and non-Hispanic populations. This study aims to evaluate these disparities across different racial groups. Patients and methods: We conducted a retrospective cohort study using SEER data from 2018 to 2021, including 18,984 patients diagnosed with gastric cancer. Patients were selected based on ICD-O-3 codes for "stomach" with malignant behavior. Using ordered logistic regression, the association between race and stage at diagnosis was analyzed, while Cox proportional hazards models were used to assess OS and CSS. Results: Hispanic patients were significantly more likely to be diagnosed at a later stage compared to non-Hispanic patients (OR: 1.19; 95% CI: 1.10–1.28). Both Hispanic and Black patients had worse OS compared to Non-Hispanic Whites (HR 1.10 CI 1.03–1.17, p = 0.003 and HR 1.13 CI 1.04–1.22, p = 0.002, respectively) as well as CSS. Conclusions: Hispanic patients are more likely to be diagnosed with advanced-stage gastric cancer and have poorer survival outcomes compared to non-Hispanic Whites. These disparities may be linked to differences in healthcare access, insurance, language barriers, and preventive care utilization. [ABSTRACT FROM AUTHOR]

Background: The relationship between the combination of platelet count and neutrophil‐lymphocyte ratio (COP‐NLR) and prognosis in patients with advanced non‐small cell lung cancer (NSCLC) treated with immune checkpoint inhibitor (ICI) combination therapy with chemotherapy remains unclear. Thus, we investigated prognostic factors, including the COP‐NLR, to identify patients who could benefit from the therapeutic efficacy of ICI combination therapy for advanced NSCLC. Furthermore, we evaluated the relationship between the COP‐NLR score during ICI combination therapy and treatment response. Methods: We conducted a retrospective cohort study of 88 patients with NSCLC who initially received ICI combination therapy. The primary outcome was overall survival (OS). The prognostic factors were extracted using the Cox proportional hazards model. The relationship between COP‐NLR score at 3 weeks after starting ICI combination therapy and a good response (complete response [CR] and partial response [PR]) to treatment was analyzed using the chi‐square test. Results: The median OS was 15.7 months. In the multivariable analysis, Eastern Cooperative Oncology Group Performance Status (ECOG PS) 2, distant metastatic sites ≥2, and baseline COP‐NLR scores of 1, 2 were extracted as significant poor prognostic factors. The proportion of patients with CR and PR in the 3‐week COP‐NLR score of 0 group was significantly higher than that in scores of 1, 2 group. Conclusions: Baseline COP‐NLR, ECOG PS, and number of distant metastatic sites were prognostic factors in patients with NSCLC with ICI combination therapy. A lower 3‐week COP‐NLR was associated with a good response to treatment. [ABSTRACT FROM AUTHOR]

Background: Patients with programmed cell death‐ligand 1 (PD‐L1) ≥50% metastatic non‐small cell lung cancer (NSCLC) treated with first‐line immunotherapy showed heterogeneous tumor responses. In this study, we investigated the clinical and immune‐inflammatory markers distinguishing patients with metastatic NSCLC achieving high depth of tumor response (HDPR) from those with non‐high depth of response (NHDPR). The impact of clinical features on the prognosis of patients with PD‐L1 ≥50% were further clarified. Methods: The clinical characteristics and immune‐inflammatory markers of 17 patients with PD‐L1 ≥50% metastatic NSCLC at Beijing Tiantan Hospital between July 2020 and December 2023 were retrospectively analyzed. Results: Among the 17 patients, seven (41.2%) patients achieved HDPR (range: −50%, −72%) and 10 (58.8%) patients achieved NHDPR (range: −13%, −45%). Below normal CD4 + T lymphocytes/CD8 + T lymphocytes (CD4/CD8) ratio (p = 0.01) and oncogenes and/or tumor suppressor gene mutations (TP53/KRAS/EGFR) (p = 0.001) were found enriched for NHDPR compared with HDPR. With a median follow‐up of 26.0 months (range: 17.2–34.8 months), the median progression‐free survival (PFS) following first‐line immunotherapy and overall survival (OS) were 9.0 months (95% CI: 5.0–13.0) and not reached (NR), respectively. The neutrophil‐to‐lymphocyte ratio (NLR) was identified as an independent prognostic factor on first‐line PFS. Patients with an NLR ≥4 exhibited a shorter median PFS (7.0 months vs. NR; p = 0.033; 95% CI: 1.2–80.2) than those with an NLR <4 following first‐line immunotherapy. Conclusions: Among patients with PD‐L1 ≥50% metastatic NSCLC who received first‐line immunotherapy, a lower CD4/CD8 ratio and the presence of genes mutations showed a diminished tumor response and a higher NLR ratio exhibited a worse median PFS.

Background. Breast cancer is an important cause of cancer‐related death in women worldwide and represents the second most frequent cause of brain metastases after lung cancer. The aim of this study was to determine the characteristics and outcomes of triple‐negative breast cancer (TNBC) patients with brain metastasis (BM). Methods. We retrospectively reviewed a cohort of patients diagnosed with TNBC at the "Instituto Nacional de Enfermedades Neoplasicas" (period 2000–2014) to evaluate patients who developed BM. Survival rates were assessed by the Kaplan–Meier method, and prognostic factors were identified with the Cox regression analysis. Results. Of a total of 2007 TNBC patients, 193 (9.62%) developed BM. Of these, 169 stages I–III patients with a median age of 45 years (range:21–78) were included. The stage in this cohort was 4 (2.4%) clinical stage (CS) I, 23 (13.6%) with CS II and 142 (84.0%) with CS III. Most of these patients presented ECOG ≥2 (68.6%). The most common symptom was headache (74.0%), followed by nausea‐vomiting (46.7%). Imaging showed that 80 patients (53.0%) had ≥1 metastatic brain lesion. Regarding the treatment of BM in this cohort, 132 patients (84.6%) received radiotherapy (RT), 2 (1.5%) surgery, and 6 (4.5%) surgery plus RT. The overall survival (OS) rate of BM was 59.8%, 37.3%, and 15.0% at 3, 6, and 12 months, respectively. A multivariate analysis showed RT to be the only factor with a positive impact on the OS of BM (hazard ratio (HR) = 0.48, 95% confidence interval (CI):0.30‐0.77, and p = 0.002), while ECOG ≥2 was associated with a worse OS (HR = 1.69, 95%CI:1.15–2.48, and p = 0.007). Conclusion. Despite the poor prognosis of TNBC patients who develop BM, RT showed a benefit in OS rates, while ECOG ≥2 was the only prognostic factor associated with a worse OS. These results may be useful for multidisciplinary teams for treatment planning in patients with TNBC and BM. [ABSTRACT FROM AUTHOR]

Purpose: This study aimed to analyse the clinical outcomes of preoperative adjuvant denosumab therapy (PADT) combined with resection and arthrodesis for recurrent grade 3 giant cell tumor of bone (GCTB) in the distal radius. Methods: A retrospective study was conducted on twenty-three patients (8 males, 15 females) who were treated with the adjuvant denosumab combined with en bloc resection (EBR) and arthrodesis for biopsy confirmed recurrent Campanacci III giant cell tumor of bone in the distal radius between January 2015 and December 2022. All 23 patients were treated with wrist arthrodesis reconstruction using autogenous free iliac crest bone graft (ICBG), bridging plate and screws. The local control, metastasis and overall survival were evaluated during the follow-up period. Functional outcomes were evaluated using the Disabilities of the Arm, Shoulder and Hand (DASH) score, Musculoskeletal Tumor Society Score (MSTS-87 and MSTS-93), and grip strength in the follow-up period. Additionally, all surgical or denosumab-related complications that occurred were recorded in this study. Results: Twenty-three patients were included in this retrospective study and no patients were lost in the follow-up period. The average patient age was 32.5 ± 10.2 years (range, 19–53 years) and the mean follow-up time was 35.5 ± 18.4 months (range, 13–72 months). The average tumor length was 71.7 ± 8.7 mm (range, 50 to 85 mm) and bone reconstruction length was 78.5 ± 8.5 mm (range, 60 to 90 mm). Four patients (17.4%) had secondary local recurrence after reoperation and two patients had (8.7%) multiple recurrences. One patient (4.3%) was deceased in the last follow-up due to multiple metastases. The estimated 5-year recurrence-free survival rate was 81.3% and 5-year metastasis-free survival rate was 95.7%. The mean union time was 8.5 ± 1.9 (6–12) months and the overall survivorship of the allograft was 82.7% (21/23) at an average 35 month follow-up. The average MSTS-87 and MSTS-93 scores were 27.8 ± 1.6 (range, from 23 to 30) and 91.5 ± 5.0 (range, from 76 to 100), and the average DASH score was 8.9 ± 3.2 (range, from 3 to 15), respectively. The average grip strength was 64.6 ± 15.7% (range, from 30 to 95%) of the uninvolved side. Eight patients (34.7%) had at least one complication in the follow-up time. Two autografts (8.7%) were removed due to local recurrence and bone nonunion, and the average autograft survival time was 32.8 ± 18.5 months (range, 12 to 72 months). Conclusions: Preoperative adjuvant denosumab therapy (PADT) combined with en bloc resection and arthrodesis is a promising method for the treatment of recurrent Campanacci III GCTB in distal radius with acceptable short-term local control and functional satisfaction. Level of evidence: level IV Therapeutic. [ABSTRACT FROM AUTHOR]

Simple Summary: Myxoid liposarcoma (MLPS) is a rare soft tissue sarcoma, often affecting the proximal extremity. There is currently limited literature describing MLPS in older individuals. This retrospective study describes treatment outcomes and tolerability in older patients treated for non-metastatic MLPS. The study shows that older patients with MLPS tolerated systemic therapy, radiation therapy, and surgery with few toxicities. Background: Myxoid liposarcoma predominantly affects young and middle-aged individuals, and little is known regarding treatment tolerability and outcomes in older patients. This study aims to better understand this older patient population. Methods: This single institution retrospective study included patients aged 70 years and older with localized (non-metastatic) myxoid liposarcoma. Results: Sixteen patients were included. The median age was 75 years, and 9 (56%) were female. Fourteen (88%) were extremity tumors and two (12%) were trunk. The median tumor size was 10.4 cm (range, 3.6 to 28 cm). Five (31%) tumors had a round cell component. All patients had surgery. Fourteen (88%) had perioperative radiation, and three (19%) had perioperative chemotherapy. One patient had postoperative infection, and one patient had neutropenic fever from preoperative chemotherapy. The median follow up from surgery was 6.3 years. Eight (50%) patients died from MLPS. The median relapse-free survival and overall survival were 34 months and 75 months, respectively. Conclusions: Most older patients with localized MLPS received perioperative radiation therapy with surgery, and few serious toxicities were reported. Even with treatment, half of the patients relapsed. [ABSTRACT FROM AUTHOR]

Simple Summary: The no specific molecular profile (NSMP) subtype of endometrial cancers remains a poorly understood class from a molecular standpoint, with a wide range of prognoses due to their internal heterogeneity. In this article, we confirm the value of a previously proposed further subdivision of NSMP into two risk classes: low-risk and high-risk; they are characterized by marked differences in oncological outcomes, including both the risk of recurrence and mortality. We are confident that this subdivision could bring significant benefits in the near future, not only in terms of modulating adjuvant therapy but also in standardizing research cohorts for more consistent and reproducible data. (1) Background: Endometrial carcinoma (EC) classified as no specific molecular profile (NSMP) represents a heterogeneous group with variable prognoses. This retrospective, single-center study aims to further stratify NSMP ECs to tailor treatment strategies and improve outcomes. (2) Methods: From 2020 to 2023, we collected data on 51 patients diagnosed with NSMP EC following the introduction of molecular profiling at our institution. Patients were retrospectively analyzed for estrogen receptor (ER) status, histotype, and grade to identify potential prognostic subgroups. (3) Results: Our analysis identified two distinct subgroups within NSMP EC: low-risk and high-risk, based on ER status, histotype, and grade. The low-risk NSMP group demonstrated significantly better survival outcomes compared to the high-risk group. With a median follow-up time of 16 moths (IQR 13.0–29.7), the disease-free survival (DFS) and overall survival (OS) for the low-risk group were 100%. For the high-risk group, the DFS and OS were 71.4% and 78.6%, respectively, which showed a statistically significantly difference (Log-Rank Mantel-Cox < 0.001). In the high-risk group, four patients experienced recurrence, and three of these patients died. (4) Conclusions: Stratifying NSMP EC into low-risk and high-risk categories based on ER status, histotype, and grade can lead to more accurate prognostic assessments. In time, it may require tailored adjuvant therapies and a personalized treatment. [ABSTRACT FROM AUTHOR]

Simple Summary: Relapses of acute promyelocytic leukemia (APL) remain a challenge despite the introduction of all-trans retinoic acid (ATRA) and arsenic trioxide (ATO). Given the variability in salvage therapies and emerging evidence supporting the deferral of hematopoietic cell transplantation (HCT) in patients receiving ATO, we analyzed the outcomes of a multicentric cohort of 67 relapsed APL patients. Better outcomes were reported with ATO ± ATRA compared to chemo-based regimens and ATRA ± Gemtuzumab ozogamicin (GO). A significant survival advantage was observed for patients undergoing HCT in the chemo-based cohort (p = 0.017), but not in the ATO-based group (p = 0.12). Achieving molecular complete remission (CR) post salvage therapy emerged as the main prognostic factor for second relapses in both univariate and multivariate analyses. Our findings support the efficacy of ATO-based therapies in first relapse and enhance the role of molecular remission as an independent outcome predictor in both first and second APL relapses. Background: The introduction of all-trans retinoic acid (ATRA) and arsenic trioxide (ATO) has radically improved the prognosis of acute promyelocytic leukemia (APL), with cure rates above 80%. While relapse occurs in less than 20% of cases, addressing this issue remains challenging. Identifying effective salvage therapies for relapsed APL is crucial to improve patient outcomes. Methods: A retrospective analysis was performed on a multicentric cohort of 67 APL patients in first relapse, treated in three Italian hematology centers from June 1981 to November 2021. The overall survival (OS) and cumulative incidence of relapse (CIR) were calculated, and predictive factors were assessed using Cox regression models. Results: Overall, 61 patients (91%) received ATO ± ATRA (40.3%), chemo-based regimens (40.3%), or ATRA ± Gemtuzumab ozogamicin (GO) (10.4%). Complete remission (CR) was achieved in 98.2% of patients (molecular CR, n = 71.4%). With a median follow-up time of 54.5 months, the 5-year OS was 73% in the ATO ± ATRA group, 44% in the chemo-based group, and 29% in the ATRA ± GO group (p = 0.035). The 5-year OS rate was also higher for transplant recipients vs. non-recipients within the chemo-based cohort (50% vs. 33%, p = 0.017), but not in the ATO-based cohort (p = 0.12). ATO-based salvage therapy resulted in better OS in both univariate (p = 0.025) and multivariate analyses (p = 0.026). The 2-year CIR was higher in patients without molecular CR vs. patients in molecular CR (66% vs. 24%, p = 0.034). Molecular CR was a significant predictor of second relapse in both univariate (p = 0.035) and multivariate analyses (p = 0.036). Conclusions: Our findings support the efficacy of ATO-based therapies in first relapse of APL and confirm the achievement of molecular remission as an independent outcome predictor in both first and second APL relapse.

Simple Summary: Upfront novel androgen receptor signaling inhibitors (ARSIs) are the first-line treatment for metastatic castration-sensitive prostate cancer (mCSPC). However, there are a certain number of cases in which androgen deprivation therapy (ADT) is more effective in patients of Asian descent. If we can identify patients who show a marked response to ADT within 12 weeks after ADT, which is the inclusion criterion for upfront ARSI clinical trials, it would be valuable from an economic standpoint. A total of 218 patients who received ADT treatment at Kanazawa University Hospital between 2000 and 2020 were included in this study. Multivariate analysis revealed that a decrease in PSA levels of <95% at 12 weeks after ADT initiation was a predictor of short time to castration resistance (TTCR) in low-risk patients. We propose a new treatment strategy, in which patients with low-risk mCSPC are treated with ADT and switched to ARSIs, based on the rate of PSA reduction at 12 weeks. Background: The treatment strategy for metastatic castration-sensitive prostate cancer (mCSPC) has changed significantly in recent years. Based on various guidelines, an upfront androgen receptor signaling inhibitor (ARSI) is the first choice, but in patients of Asian descent, including Japanese patients, there are a certain number of cases in which androgen deprivation therapy (ADT) and CAB are more effective. If patients can be identified who show a marked response to ADT within 12 weeks after the initiation of ADT, which is the inclusion criterion for ARSI clinical trials targeting mCSPC, it would be valuable from an economic standpoint. Methods: A total of 218 patients with pure prostate adenocarcinoma and treated with ADT at the Kanazawa University Hospital between January 2000 and December 2020 were included in this study. As a risk classification for mCSPC, in addition to the LATITUDE and CHAARTED criteria, we used the castration-sensitive prostate cancer classification proposed by Kanazawa University (Canazawa), developed by the Department of Urology of Kanazawa University. The Canazawa classification was based on three factors: Gleason pattern 5, bone scan index (BSI) ≥ 1.5, and lactate dehydrogenase (LDH) ≥ 300 IU/L. It defined patients with one factor or less as low-risk and patients with two or three factors as high-risk. The overall survival (OS) and time to castration resistance (TTCR) were estimated retrospectively using the Kaplan–Meier method, and factors associated with TTCR were identified using univariate and multivariate analyses. Results: The median follow-up period was 40.4 months, the median OS period was 85.2 months, and the median TTCR period was 16.4 months. The Canazawa risk classification provided the clearest distinction between the OS and TTCR in mCSPC patients. Multivariate analysis revealed a decrease in PSA levels of <95% at 12 weeks after ADT initiation and was a predictor of short TTCR in low-risk, low-volume patients across all risk classifications. Conclusion: The Canazawa classification differentiated the prognosis of mCSPC patients more clearly. A PSA reduction rate of <95% at 12 w after starting ADT in low-risk, low-volume patients of all risk classifications was significantly shorter than the TTCR. We propose a new treatment strategy, in which patients with low-risk mCSPC are treated with ADT and switched to ARSIs based on the rate of PSA reduction at 12 w. [ABSTRACT FROM AUTHOR]

Simple Summary: Approximately 40% of all diagnoses of rectal cancer in Spain are locally advanced. A multimodal treatment is needed, and one of its pillars is radiotherapy, with a classic dose scheme of up to 50–50.4 Gy concomitantly with oral capecitabine or 5-fluorouracil. Dose escalation is being explored to achieve higher rates of a pathological complete response, but the optimal dose and its impact on the outcomes are unclear. Our study aimed to evaluate the percentage of complete pathological responses obtained with an intensified neoadjuvant radiotherapy treatment scheme. We confirmed in a homogeneous population (49 patients treated with standard radiotherapy vs. 50 patients treated with dose-escalated radiotherapy) higher rates of a pathological complete response with a dose of up to 54 Gy concomitantly with oral capecitabine. Neoadjuvant radiotherapy intensification is useful for specimen sterilization and should be offered to selected patients. Locally advanced rectal cancer requires a multimodal treatment. Radiotherapy is being explored for intensification to improve the rates of pathological complete responses (ypCR rates) which are correlated with better outcomes. This study reports a comparison between standard versus escalated doses in a preoperative scenario. The ypCR rates, toxicity, postoperative complications, and disease-free and overall survival at 5 years are described. From 2012 to 2019, 99 patients were analyzed retrospectively: standard arm (mean of 47.5 Gy) vs. dose-escalated arm (mean of 54.3 Gy). All patients were treated with 3DRT in 25 fractions, with concomitant capecitabine and surgery performed according to the total mesorectal excision principles in both arms. The ypCR was reported using the "College of American Pathologist grades"; the gastrointestinal (GI) and genitourinary (GU) toxicity was reported using the "Common Terminology Criteria for Adverse Events" (CTCAE 4.0). The ypCR rates were higher in the dose-escalated group (25% vs. 10.64%; p = 0.07), with a lower rate of non-treatment response (61.36% vs. 38.64%; p = 0.11). No statistical differences between the arms were found in terms of the oncological outcomes, postoperative complications (p = 0.15), second surgeries (p = 0.62), or deaths (p = 0.62). The CTCAE acute GI and GU toxicity were grade I or II in both arms. Our study presents a long-term follow-up in comparative cohorts. [ABSTRACT FROM AUTHOR]

Background: Maintaining the dose-intensity of cancer treatment is an important prognostic factor of aggressive hematological malignancies. The objective of this study was to assess the long-term outcomes of intensive care unit (ICU) survivors with acute myeloid leukemia (AML) or aggressive B-cell non-Hodgkin lymphoma (B-NHL) with emphasis on the resumption of the intended optimal regimen of cancer treatment. Patients and methods: We conducted a retrospective (2013–2021) single-center observational study where we included patients with AML and B-NHL discharged alive from the ICU after an unplanned admission. The primary endpoint was the change in the intended optimal cancer treatment following ICU discharge. Secondary endpoints were 1-year progression-free survival and overall survival rates. Determinants associated with modifications in cancer treatment were assessed through multivariate logistic regression. Results: Over the study period, 366 patients with AML or B-NHL were admitted to the ICU, of whom 170 survivors with AML (n = 92) and B-NHL (n = 78) formed the cohort of interest. The hematological malignancy was recently diagnosed in 68% of patients. The admission Sequential Organ Failure Assessment (SOFA) score was 5 (interquartile range 4–8). During the ICU stay, 30 patients (17.6%) required invasive mechanical ventilation, 29 (17.0%) vasopressor support, and 16 (9.4%) renal replacement therapy. The one-year survival rate following ICU discharge was 59.5%. Further modifications in hematologic treatment regimens were required in 72 patients (42%). In multivariate analysis, age > 65 years (odds ratio (OR) 3.54 [95%-confidence interval 1.67–7.50], p < 0.001), ICU-discharge hyperbilirubinemia > 20 µmol/L (OR 3.01 [1.10–8.15], p = 0.031), and therapeutic limitations (OR 16.5 [1.83–149.7], p = 0.012) were independently associated with modifications in cancer treatment. Post-ICU modifications of cancer treatment had significant impact on in-hospital, 1-year overall survival and progression-free survival. Conclusion: The intended cancer treatment could be resumed in 58% of ICU survivors with aggressive hematological malignancies. At the time of ICU discharge, advanced age, persistent liver dysfunction and decisions to limit further life-support therapies were independent determinants of cancer treatment modifications. These modifications were associated with worsened one-year outcomes. [ABSTRACT FROM AUTHOR]

Simple Summary: In this retrospective study of 61 patients with diffuse gliomas, APT-weighted imaging in the solid tumor component provided quantitative metrics associated with WHO grade and survival. Mean APT values of the necrotic component showed high variability between subjects, warranting further investigation. These results highlight the importance of assessing the different tumor components with APT-weighted imaging, to provide useful diagnostic and prognostic information for the management of patients with gliomas. Amide Proton Transfer-weighted (APTw) imaging is a molecular MRI technique used to quantify protein concentrations in gliomas, which have heterogeneous components with varying cellularity and metabolic activity. This study aimed to assess the correlation between the component-specific APT signal of the neoplasm and WHO grade, molecular profile and survival status. Sixty-one patients with adult-type diffuse gliomas were retrospectively analyzed. APT values were semi-automatically extracted from tumor solid and, whenever present, necrotic components. APT values were compared between groups stratified by WHO grade, IDH-mutation, MGMT promoter methylation and 1- and 2-year survival status using Wilcoxon rank-sum test, adjusting for multiple comparisons. Overall survival (OS) was analyzed in the subgroup of 48 patients with grade 4 tumors using Cox proportional-hazards models. Random-effects models were used to assess inter-subject heterogeneity of the mean APT values in each tumor component. APT values of the solid component significantly differed between patients with grades 2–3 and 4 tumors (mean 1.58 ± 0.50 vs. 2.04 ± 0.56, p = 0.028) and correlated with OS after 1 year (1.81 ± 0.58 in survivors vs. 2.17 ± 0.51 in deceased patients, p = 0.030). APT values did not differ by IDH-mutation, MGMT methylation, and 2-year survival status. Within grade 4 glioma patients, higher APT kurtosis of the solid component was a negative prognostic factor (hazard ratio = 1.60, p = 0.040). Mean APT values of the necrosis showed high inter-subject variability, although most necrotic tumors were grade 4 and IDH wildtype. In conclusion, APTw imaging in the solid component provided metrics associated with glioma grade and survival status but showed weak correlation with IDH-mutation and MGMT promoter methylation status, in contrast to previous works. Further research is needed to understand APT signal variability within the necrotic component of high-grade gliomas. [ABSTRACT FROM AUTHOR]

Simple Summary: Peritoneal metastases from gastric cancer are linked to a poor prognosis, with median survival ranging from 2 to 9 months. Standard treatments, including systemic chemotherapy and targeted therapies, have demonstrated only limited effectiveness. Pressurized intraperitoneal aerosol chemotherapy (PIPAC) is an experimental approach under investigation for treating these metastases, but its widespread clinical use is hindered by insufficient evidence regarding its safety and efficacy. This retrospective study presents outcomes from the first PIPAC program in Lithuania, where 32 patients underwent 71 PIPAC procedures between 2015 and 2022. Intraoperative and postoperative complications occurred in 4.2% of cases. Although reductions in peritoneal carcinomatosis index (PCI) and ascites volume were noted, they were not statistically significant. The median overall survival after PM diagnosis was 12.5 months. These findings suggest that PIPAC is a safe and feasible treatment, but further research is needed to establish its efficacy. Background: Peritoneal metastases (PM) of gastric cancer (GC) are considered a terminal condition, with reported median survival ranging from 2 to 9 months. Standard treatment typically involves systemic chemotherapy alone or combined with targeted therapy or immunotherapy, though efficacy is limited. Pressurized intraperitoneal aerosol chemotherapy (PIPAC) has emerged as a novel technique for treating GC PM, although it remains an experimental treatment under investigation. This study aimed to summarize the outcomes of GC PM treatment with PIPAC from the Lithuanian PIPAC program. Methods: All patients who underwent PIPAC for GC PM at Vilnius University Hospital Santaros Klinikos between 2015 and 2022 were included in this retrospective study. The safety of PIPAC was assessed by postoperative complications according to the Clavien–Dindo classification. Efficacy was evaluated based on the peritoneal carcinomatosis index (PCI), ascites dynamics throughout the treatment, and long-term outcomes. Results: In total, 32 patients underwent 71 PIPAC procedures. Intraoperative and postoperative morbidity related to PIPAC occurred after three (4.2%) procedures. Following PIPAC, there was a tendency towards a decrease in median PCI from 10 (Q1 3; Q3 13) to 7 (Q1 2; Q3 12), p = 0.75, and a decrease in median ascites volume from 1300 mL (Q1 500; Q3 3600) at the first PIPAC to 700 mL (Q1 250; Q3 4750) at the last PIPAC, p = 0.56; however, these differences were not statistically significant. The median overall survival after PM diagnosis was 12.5 months (95% CI 10–17), and the median survival after the first PIPAC procedure was 5 months (95% CI 4–10). Conclusions: PIPAC is a safe and feasible treatment option for GC PM; however, well-designed prospective studies are needed to fully assess its efficacy. [ABSTRACT FROM AUTHOR]

Simple Summary: This study examined the outcomes of patients with gallbladder cancer over 20 years in Saskatchewan, Canada, focusing on geographic, demographic, and clinical factors. A total of 331 patients diagnosed between 2000 and 2019 were included. The majority (64%) had advanced stage 4 disease, with a significant proportion (66%) being rural residents. Key factors associated with poorer overall survival included stage 4 disease, lack of surgery, older age, a higher neutrophil-to-lymphocyte ratio, and no referral to a regional cancer center. Among early-stage patients, stage III disease and urban residence were associated with worse disease-free survival. The findings highlight the late-stage diagnosis and referral challenges impacting the outcomes of gallbladder cancer. Background: Gallbladder cancer (GBC) is an uncommon cancer. This study aimed to determine the outcomes of GBC in relation to geographic, demographic, and clinical factors in a Canadian province from 2000 to 2019. Methods: This population-based retrospective cohort study included all patients diagnosed with gallbladder cancer (GBC) in Saskatchewan, Canada, from 2000 to 2019. Cox proportional multivariate regression analysis was conducted to identify factors associated with poorer outcomes. Results: In total, 331 patients with a median age of 74 years and male–female ratio of 1:2 were identified. Of these patients, 305 (92%) had a pathological diagnosis of GBC. Among patients with documented staging data, 64% had stage IV disease. A total of 217 (66%) patients were rural residents, and 149 (45%) were referred to a cancer center. The multivariate analysis for patients with stage I–III GBC showed that stage III disease [hazard ratio (HR), 2.63; 95% confidence interval (CI), 1.09–6.34)] and urban residence (HR, 2.20; 95% CI, 1.1–4.39) were correlated with inferior disease-free survival. For all patients, stage IV disease (HR, 3.02; 95% CI, 1.85–4.94), no referral to a cancer center (HR, 2.64; 95% CI, 1.51–4.62), lack of surgery (HR, 1.63; 95% CI, 1.03–2.57), a neutrophil–lymphocyte ratio of >3.2 (HR, 1.57; 1.05–2.36), and age of ≥70 years (HR, 1.51; 95% CI, 1.04–2.19) were correlated with inferior overall survival. Conclusions: In this real-world context, the majority of patients with GBC were diagnosed at a late stage and were not referred to a cancer center. For those with early-stage GBC, living in an urban area and having stage III disease were linked to worse outcomes. Across all stages of GBC, stage IV disease, older age, absence of surgery, lack of referral to a cancer center, and a high neutrophil-to-lymphocyte ratio were associated with poorer survival.

Background: Chemotherapy‐induced anorexia is a common occurrence in patients undergoing treatment for advanced lung cancer. However, the relationship between chemotherapy‐induced anorexia and weight loss during platinum‐based chemotherapy combined with immune checkpoint inhibitors is unclear. This study explored the relationship between chemotherapy‐induced anorexia and therapeutic outcomes in patients with stage IV non‐small‐cell lung cancer undergoing platinum‐based chemotherapy combined with immune checkpoint inhibitors. Methods: The study retrospectively reviewed the medical records of 106 patients with stage IV non‐small‐cell lung cancer treated with platinum‐based chemotherapy and immune checkpoint inhibitors between January 2019 and October 2022. The incidence of weight loss and its association with treatment efficacy was assessed in the chemotherapy‐induced anorexia group. Chemotherapy‐induced anorexia, nausea, and vomiting were evaluated using Common Terminology Criteria for Adverse Events v 5.0. Progression‐free and overall survival were used to measure treatment efficacy. Results: Chemotherapy‐induced anorexia was observed in 13.2% of patients. These patients exhibited significant weight loss at 6 and 9 weeks after treatment initiation compared to those in the non‐chemotherapy‐induced anorexia group. Progression‐free and overall survival were shorter in the chemotherapy‐induced anorexia group than in the non‐chemotherapy‐induced anorexia group, but the difference was not statistically significant. Conclusions: Chemotherapy‐induced anorexia was associated with significant weight loss and reduced treatment efficacy in patients with stage IV non‐small‐cell lung cancer. These results highlight the importance of implementing robust supportive care for chemotherapy‐induced anorexia to mitigate weight loss and uphold treatment effectiveness during platinum‐based chemotherapy combined with immune checkpoint inhibitors.

Introduction: Limited data exist on interphase fluorescent in situ hybridization (iFISH)-based survival outcomes in newly diagnosed multiple myeloma (NDMM) from India. Objectives: To study the demographics and iFISH-based survival outcomes in NDMM patients treated with proteasome inhibitors from a community-based cancer setup. Materials and Methods: We reviewed the records of 25 patients treated with proteasome inhibitors between June 2017 and April 2023 using five high-risk (HR) iFISH markers based on mSMART 3.0. Results: The median age was 60 years (range 34–87). HR iFISH was detected in 12 (48%) patients. With a median follow-up of 27 months, the overall response at the last follow-up was 80% (very good partial response - 52%, complete remission - 20%, and partial response - 8%), with 8 (32%) relapses. Twenty (80%) patients remain alive, with five deaths in HR (sepsis [ n = 3]). The 2.5-year overall survival in HR and standard risk was 55.6% ± 15.2% and 100% (P = 0.01), and event-free survival was 32.4% ± 16.5% and 77.8% ± 13.8% (P = 0.02), respectively. Conclusions: Using limited iFISH HR markers helps in the early and effective stratification of NDMM in the real world. Sepsis remains an important cause of mortality in an Indian setup.

) Objective To explore effective treatments and prognostic factors for diffuse intrinsic pontine glioma (DIPG). Methods Clinical and imaging information and survival data of 14 DIPG patients, treated with radiotherapy combined with temozolomide and nitolizumab or radiotherapy combined with ACT001, were retrospectively analysed at Beijing Tiantan Hospital, Capital Medical University from April 2021 to January 2024. The median progression free survival (PFS) and overall survival (OS) were calculated using Kaplan - Meier survival curves, and multifactorial Cox regression analysis was used to investigate the effects of different factors on PFS and OS. Results The objective response rate (ORR) was 10/14, and the median PFS and OS were 7.83 and 8.30 months, respectively. Multfactorial Cox regression analysis identified the absence of enhancement on baseline imaging as a good prognostic variable for both PFS (RR = 0.052, 95%CI: 0.006-0.416; P = 0.005) and OS (RR = 0.046, 95%CI: 0.005-0.413; P = 0.006), while male (RR = 0.085, 95%CI: 0.009-0.764; P = 0.028), older age (RR = 0.631, 95%CI: 0.423-0.942; P = 0.024), and the absence of symptoms of cranial nerve involvement at the onset (RR = 0.116, 95%CI: 0.017- 0.781; P = 0.027) were also good prognostic variables for OS. Conclusions Female, younger age at diagnosis, cranial nerve involvement at the onset, and enhancement on baseline imaging are risk factors for the survival of children with DIPG.

Serum carbohydrate antigen 19-9 (Ca19-9) is the only approved biomarker approved for the screening and diagnosis of pancreatic cancer (PC), but its value remains controversial. The aim of our study is to evaluate the role of CA 19-9 in the management of PC patients in jaundiced patients staged by both Computed Tomography (CT) and Endoscopic Ultrasound (EUS). Additionally, we evaluated traditional cholestasis marker behavior. Medical records of 73 patients have been retrospectively reviewed. We considered tumor size, tumor stage, CA 19-9, cytolysis, and cholestasis biomarkers. All patients underwent CT scan for staging. EUS +/− fine-needle biopsy (FNB) was performed in doubtful cases. Median alkaline phosphatase (ALP) and y-glutamyltransferase (GGT) levels were significantly lower compared to baseline after the biliary drainage (204 vs. 465 U/L, p < 0.0001, 204. U/L vs. 608.5, p < 0.0001, respectively), whilst no differences were observed for CA 19-9 levels. CA 19-9 showed significant association with the tumor stage in the pre-drainage setting. CT and EUS showed a low agreement in estimating tumor size (mean difference 4.8 mm 95% LoA −10.82–20.38). We did not find any significant correlation between CA 19-9 and bilirubin levels (r = −0.05, p = 0.7). In our cohort, survival rate was lower in patients with higher CA 19-9 levels (log rank p = 0.007). CA 19-9 has some limitations as a biomarker in the PC setting, thus it cannot address the treatment strategy alone. Nonetheless, it provides valuable information, and is not replaceable for the time being. [ABSTRACT FROM AUTHOR]

Introduction Predictive markers of LV5FU2 maintenance benefit after first-line induction with FOLFIRINOX in patients with metastatic pancreatic cancer are necessary to select patients who will not be harmed by this strategy. Patients and Methods We focused on patients who received 12 cycles of FOLFIRINOX (arm A, N  = 88) or 8 cycles of FOLFIRINOX followed by LV5FU2 maintenance in controlled patients (arm B, N  = 91) from the PRODIGE-35 trial. Prognostic factors and predictors of efficiency were identified by using Cox regression. Median progression-free survival (PFS), overall survival (OS), and time to deterioration of quality of life (TTD-QoL) were evaluated. Results Poor independent prognostic factors were primary tumor in place, age <65 years and the presence of liver metastases for PFS, a baseline neutrophil/lymphocyte ratio (NLR) ≥5 and CA19.9 ≥500 UI/L for OS, independent of the treatment arm. Patients with one metastatic site had a longer PFS in arm A, whereas patients with ≥2 metastatic sites had a longer PFS in arm B. We also identified predictors of OS and TTD-QoL in arm B but these differences were not statistically significant. Conclusion Except for patients with one metastatic site who benefited more from 12 cycles of FOLFIRINOX, a maintenance strategy with LV5FU2 should be widely offered to mPC patients whose survival and QoL are preserved after 4 months of FOLFIRINOX.

Introduction: A dynamic molecular biomarker that can identify early efficacy of immune checkpoint inhibitor (ICI) therapy remains an unmet clinical need. Here we evaluate if a novel circulating tumor DNA (ctDNA) assay, xM, used for treatment response monitoring (TRM), that quantifies changes in ctDNA tumor fraction (TF), can predict outcome benefits in patients treated with ICI alone or in combination with chemotherapy in a real-world (RW) cohort. Methods: This retrospective study consisted of patients with advanced cancer from the Tempus de-identified clinical genomic database who received longitudinal liquid-based next-generation sequencing. Eligible patients had a blood sample ≤ 40 days prior to the start of ICI initiation and an on-treatment blood sample 15–180 days post ICI initiation. TF was calculated via an ensemble algorithm that utilizes TF estimates derived from variants and copy number information. Patients with molecular response (MR) were defined as patients with a ≥ 50% decrease in TF between tests. In the subset of patients with rw-imaging data between 2 and 18 weeks of ICI initiation, the predictive value of MR in addition to rw-imaging was compared to a model of rw-imaging alone. Results: The evaluable cohort (N = 86) was composed of 14 solid cancer types. Patients received either ICI monotherapy (38.4%, N = 33) or ICI in combination with chemotherapy (61.6%, N = 53). Patients with MR had significantly longer rw-overall survival (rwOS) (hazard ratio (HR) 0.4, P = 0.004) and rw-progression free survival (rwPFS) (HR 0.4, P = 0.005) than patients with molecular non-response (nMR). Similar results were seen in the ICI monotherapy subcohort; HR 0.2, P = 0.02 for rwOS and HR 0.2, P = 0.01 for rwPFS. In the subset of patients with matched rw-imaging data (N = 51), a model incorporating both MR and rw-imaging was superior in predicting rwOS than rw-imaging alone (P = 0.02). Conclusions: xM used for TRM is a novel serial quantitative TF algorithm that can be used clinically to evaluate ICI therapy efficacy. [ABSTRACT FROM AUTHOR]

Introduction: Hepatic visceral crisis (VC), characterized by a rapid total bilirubin increase with disease progression, poses a life-threatening risk in advanced breast cancer (ABC). International consensus guidelines define VC and touch on impending VC (IVC). Limited data exist on systemic treatments for hepatic VC/IVC. This study explores the safety and efficacy of cisplatin monotherapy in patients with Human Epidermal Growth Factor Receptor 2- negative breast cancer (BC) and hepatic IVC/VC. Methods: In this retrospective single-center cohort study data of patients treated with cisplatin monotherapy (60–80 mg/m2, every 3–4 weeks) between 2016 and 2023 at a reference Cancer Centre in Southern Poland were analyzed. Results: 33 female patients (24/33 hormonal-positive) with the mean age 53.84 years were included. Participants progressed on median 2 prior palliative systemic treatment lines. In 10/23 patients hepatic VC and in 23/33 IVC (rapid, symptomatic liver progression; extensive liver involvement; alanine or aspartate aminotransferase > 2 × normal limit; significant increases in lactate dehydrogenase, alkaline phosphatase, or gamma-glutamyl transferase) were identified. Median progression-free survival was 1.87 months and median overall survival 2.67 months. 33% of the patients presented stable disease or partial response. Eight patients experienced adverse events grade ≥ 3: in five the dose of cisplatin was reduced; two stopped the treatment. Conclusion: Due to the hepatotoxicity of BC-active drugs, specific recommendations for systemic treatment are scarce. Our study explored cisplatin's potential use, finding it to be a viable option in patients with performance status 0 or 1 experiencing hepatic IVC/VC, irrespective of liver function parameters and other factors.

Simple Summary: This study investigated one of the treatment options for advanced breast cancer patients after they completed standard therapy that combines hormone therapy and specific targeted agents called cyclin-dependent kinase 4/6 inhibitors. We wanted to understand why in real-world patients start chemotherapy after finishing standard initial treatment, how they respond to it, and what factors might affect their outcomes. We found that chemotherapy was often used when patients faced dissemination to internal organs with the risk of further progression, but it provided limited benefits. We suggest that modern drugs recommended by guidelines before chemotherapy should be better reimbursed in Poland. This research could help doctors make better treatment decisions and improve future clinical trials. The standard therapy for hormone-receptor-positive, human epidermal growth factor receptor 2-negative advanced breast cancer includes the use of cyclin-dependent kinase 4/6 inhibitors (CDK4/6i) with endocrine therapy. The optimal post-CDK4/6i treatment sequence is unclear. This cohort study evaluated the initiation, characteristics, and outcomes of chemotherapy following CDK4/6i-based treatment. Among the 227 patients who began CDK4/6i therapy, 114 completed it. Seventy-nine female patients received further treatment, including 55 receiving chemotherapy. The average age was 60.1 years. Post-CDK4/6i chemotherapy was typically (69.1%) first-line due to an impending visceral crisis. The median progression-free survival (mPFS) was 3.0 months (range 0.5–18.9), and the median overall survival (mOS) was 8.3 months (0.5–26.1). The median OS from the end of CDK4/6i treatment was 12.4 months (1.5–26.8). In univariate analysis, neither mPFS nor mOS was associated with age, tumor grade, receptor status, Ki67 status, time from diagnosis to CDK4/6i cessation, therapy line, or CDK4/6i type. Dose reduction occurred in 12 patients (21.8%), and chemotherapy was ceased due to adverse events in 8 patients (14.6%). Chemotherapy showed limited benefit regardless of the regimen. The role of chemotherapy may evolve with broader CDK4/6i use in adjuvant treatment. [ABSTRACT FROM AUTHOR]

Simple Summary: The medical field is increasingly interested in using machine learning (ML) to analyse data, sparking a debate on whether ML is better than traditional statistical modelling. The aim of our retrospective study was to investigate the use of statistical models versus ML to predict survival in patients with osteosarcoma using low-dimensional data from the EURAMOS-1 trial. Results showed that ML did not add much value in this context, which involved data from nearly 2000 patients and eight predictors. Traditional statistical models worked well without needing extensive complex training, unlike ML, and they showed better effectiveness overall because they are easy to understand and use. The article helps healthcare researchers assess different prediction models in similar low-dimensional contexts. Since the mid-1980s, there has been little progress in improving survival of patients diagnosed with osteosarcoma. Survival prediction models play a key role in clinical decision-making, guiding healthcare professionals in tailoring treatment strategies based on individual patient risks. The increasing interest of the medical community in using machine learning (ML) for predicting survival has sparked an ongoing debate on the value of ML techniques versus more traditional statistical modelling (SM) approaches. This study investigates the use of SM versus ML methods in predicting overall survival (OS) using osteosarcoma data from the EURAMOS-1 clinical trial (NCT00134030). The well-established Cox proportional hazard model is compared to the extended Cox model that includes time-varying effects, and to the ML methods random survival forests and survival neural networks. The impact of eight variables on OS predictions is explored. Results are compared on different model performance metrics, variable importance, and patient-specific predictions. The article provides comprehensive insights to aid healthcare researchers in evaluating diverse survival prediction models for low-dimensional clinical data. [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: Although the high mutation burden in small-cell lung cancer (SCLC) suggests that it should be responsive to immune checkpoint blockade (ICB), relatively few patients have shown durable clinical benefit (DCB). To identify biomarkers of responses, biopsies from 35 patients treated with ICB (21 first-line and 14 second-line) were subjected to transcriptomic analysis and gene signatures were studied. Patients with DCB were compared to those with no clinical benefit (NCB). The response to ICB in the second-line, but not the first-line, setting was associated with gene signatures of inflammation, antigen presentation, interferon responses, and increased CD8 T cells. Our data suggest that responses to ICB in the second-line setting can be predicted by the baseline inflammatory state of the tumor; however, this strong association with inflammation was not observed in the first-line setting, likely because chemotherapy alters the immune milieu allowing a response to ICB. Although immune checkpoint blockade (ICB) is currently approved for the treatment of extensive-stage small-cell lung cancer (SCLC) in combination with chemotherapy, relatively few patients have demonstrated durable clinical benefit (DCB) to these therapies. Biomarkers predicting responses are needed. Biopsies from 35 SCLC patients treated with ICB were subjected to transcriptomic analysis; gene signatures were assessed for associations with responses. Twenty-one patients were treated with ICB in the first-line setting in combination with platinum-based chemotherapy; fourteen patients were treated in the second-line setting with ICB alone. DCB after ICB in SCLC in the second-line setting (3 of 14 patients) was associated with statistically higher transcriptomic levels of genes associated with inflammation (p = 0.003), antigen presentation machinery (p = 0.03), interferon responses (p < 0.05), and increased CD8 T cells (p = 0.02). In contrast, these gene signatures were not significantly different in the first-line setting. Our data suggest that responses to ICB in SCLC in the second-line setting can be predicted by the baseline inflammatory state of the tumor; however, this strong association with inflammation was not seen in the first-line setting. We postulate that chemotherapy alters the immune milieu allowing a response to ICB. Other biomarkers will be needed to predict responses in first-line therapy patients. [ABSTRACT FROM AUTHOR]

Simple Summary: Mutations in the gene, TP53, define the most treatment-resistant subtype of acute myeloid leukemia (AML). Patients with TP53-mutated AML invariably develop disease recurrence after treatment, leading to short survival times. Previous studies have shown that less than 10% of these patients survive beyond 2 years after diagnosis. Moreover, the best treatment approach for these patients is still unclear. Our study is the first to analyze therapy results beyond first-line treatment, highlighting the importance of therapy sequencing in managing these patients. We found that sequential treatment with intensive chemotherapy followed by a less-intensive regimen achieved the highest remission rate of over 65%. Eligible patients should then receive blood stem cell transplantation from a donor, which significantly improves long-term survival. Our study provides crucial data to guide management and optimize therapy sequencing for better survival in this treatment-resistant disease. Background: TP53 mutations (TP53m) define the most treatment-refractory acute myeloid leukemia (AML) subtype. Optimal treatment approaches have not been established in this setting. We reviewed our institutional experience to identify therapy sequencing, treatment response, and survival patterns in these patients. Methods: This study was a single-center, retrospective cohort analysis. Results: Our cohort includes 86 TP53m and 337 TP53 wild-type (TP53wt) adult AML patients. TP53m AML patients presented with lower bone marrow and peripheral blasts; none presented with hyperleukocytosis. Patients who received intensive treatment up front demonstrated superior overall survival (OS) over those receiving first-line non-intensive therapy (2-year OS 22% versus 7%; p = 0.02). However, the complete remission (CR) rates among the first-line intensive and non-intensive therapy groups were comparable (21.9% and 29.4%, respectively, p = 0.49). The improved OS is therefore attributed to superior cumulative CR in the intensive group. First-line intensively treated patients were more likely to receive and respond to salvage, leading to a cumulative CR rate of 65.7% (versus 29.4%, p = 0.003). Achieving CR at any point is strongly associated with superior survival outcomes with 2-year OS of 31% versus 0% for those not achieving CR ever (p < 0.01). Conclusions: We find that TP53m AML rarely presents with oncological emergencies, suggesting that clinical trial enrollment is feasible in this group. Additionally, in our cohort, intensive induction therapies lead to superior survival outcomes attributed to successful salvage therapy. These data suggest that strategic therapy sequencing and salvage therapy may be important in optimizing outcomes for TP53m AML patients. [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.

Simple Summary: This study explored how genetic changes influence treatment effectiveness and survival in patients with advanced pancreatic cancer. By examining tumors from 142 patients, researchers identified specific genetic mutations that can predict how well a patient responds to chemotherapy. Findings showed that mutations in certain genetic pathways are associated with longer survival and better treatment outcomes. This research highlights the importance of tailoring cancer treatment based on individual genetic profiles, potentially leading to more personalized and effective therapies for pancreatic cancer patients. (1) Background: Pancreatic ductal adenocarcinoma (PDAC) has low survival rates despite treatment advancements. Aim: This study aims to show how molecular profiling could possibly guide personalized treatment strategies, which may help improve survival outcomes in patients with PDAC. (2) Materials and Methods: A retrospective analysis of 142 PDAC patients from a single academic center was conducted. Patients underwent chemotherapy and next-generation sequencing for molecular profiling. Key oncogenic pathways were identified using the Reactome pathway database. Survival analysis was performed using Kaplan–Meier curves and Cox Proportional Hazards Regression. (3) Results: Patients mainly received FOLFIRINOX (n = 62) or gemcitabine nab-paclitaxel (n = 62) as initial chemotherapy. The median OS was 13.6 months. Longer median OS was noted in patients with NOTCH (15 vs. 12.3 months, p = 0.007) and KIT pathway mutations (21.3 vs. 12.12 months, p = 0.04). Combinatorial pathway analysis indicated potential synergistic effects on survival. In the PFS, PI3K pathway (6.6 vs. 5.7 months, p = 0.03) and KIT pathway (10.3 vs. 6.2 months, p = 0.03) mutations correlated with improved PFS within the gemcitabine nab-paclitaxel subgroup. (4) Conclusions: Molecular profiling could play a role in PDAC for predicting outcomes and responses to therapies like FOLFIRINOX and gemcitabine nab-paclitaxel. Integrating genomic data into clinical decision-making can benefit PDAC treatment, though further validation is needed to fully utilize precision oncology in PDAC management. [ABSTRACT FROM AUTHOR]

Simple Summary: Patients with locally advanced or metastatic urothelial carcinoma have a poor prognosis. Enfortumab vedotin, administered after cisplatin-based chemotherapy and followed by immune checkpoint inhibitors, is widely known to prolong overall survival (OS). However, the predictive factors of enfortumab vedotin treatment that prolong OS remain unclear. In this study, patients who received enfortumab vedotin with shrinking tumors showed a significant increase in OS compared to those who received chemotherapy other than enfortumab vedotin or those who did not receive any treatment. Multivariate analysis identified neutrophil-to-lymphocyte ratio and dysgeusia as potential predictors of OS. Patients without these factors had a significantly prolonged OS compared to those with both factors. In real-world practice, enfortumab vedotin therapy is effective for patients with locally advanced or metastatic urothelial carcinoma. Randomized phase III trial results have demonstrated enfortumab vedotin (EV), an antibody–drug conjugate (ADC) consisting of an anti-Nectin-4 human IgG1 monoclonal antibody and monomethyl auristatin E, is a useful treatment for patients with locally advanced or metastatic urothelial carcinoma (la/mUC) that progressed after immune checkpoint inhibitor (ICI) therapies. This multicenter retrospective cohort study aimed to identify predictive factors for the efficacy of EV therapy and prolonged overall survival (OS) of patients in clinical practice. This study included patients with la/mUC who received ICI treatment. Patients who subsequently received EV treatment, those who received non-EV chemotherapy, and those who received no treatment were defined as EV, non-EV, and best supportive care (BSC) groups, respectively. The median OS was 20, 15, and 7 months in the EV, non-EV, and BSC groups, respectively (p < 0.001). Patients with la/mUC who had a complete or partial response after EV treatment had a significantly prolonged OS compared with those with stable or progressive disease. Univariate analysis showed age, neutrophil-to-lymphocyte ratio (NLR), dysgeusia, and rash as independent predictors of OS improvement. NLR and dysgeusia were independent predictors of OS after EV in multivariate analysis. Patients without these factors had a significantly prolonged OS compared to those with both factors. In real-world practice, EV therapy is an effective treatment for patients with la/mUC after ICI treatment. [ABSTRACT FROM AUTHOR]

Aim: The PREDICT tool is used to estimate survival in breast cancer patients according to the types of treatment given. This study aimed to assess the accuracy of the PREDICT tool and identify the prognostic factors for survival in patients with breast cancer. Material and Methods: A retrospective study was performed based on data collected from the Hospital Sultanah Nur Zahirah, Terengganu, Malaysia. All female patients diagnosed with stage I to IV breast cancer were identified from the year 2011 to 2017. Results: Based on data from 355 eligible patients, the predicted and observed 5-year overall survival rates were 75.8% and 75.2%, respectively. The model performed fairly well, with the area under the curve (AUC) of 0.747 (95% confidence interval (CI): 0.69-0.81) in the predicted 5-year overall survival. Among the 585 patients diagnosed with stage I to IV breast cancer, stage at the presentation (stage III hazard ratio (HR): 5.80, 95% CI: 1.69-19.94, p=0.005, stage IV HR: 10.61, 95% CI: 3.09-36.49, p<0.001), without surgical treatment (HR: 2.29, 95% CI: 1.73-3.00, p<0.001), without radiotherapy (HR: 1.92, 95% CI: 1.41-2.62, p<0.001), and without neoadjuvant chemotherapy (HR: 0.63, 95% CI: 0.47-0.86, p=0.003) were associated with death in breast cancer patients. Conclusion: The PREDICT tool accurately estimated the 5-year overall survival in the study center. It might serve as a useful prognostication tool during consultation. Late stages of the disease, patients without surgical treatment, and patients without radiotherapy were associated with a higher risk of death in breast cancer. [ABSTRACT FROM AUTHOR]

Background Platinum-based chemotherapy represents the standard first-line treatment for biliary tract cancers (BTC). Deficits in genes involved in the homologous recombination (HR) and DNA damage response (DDR) may confer higher sensitivity to platinum agents. Methods We retrospectively included patients affected by BTC from 2 Italian institutions. Inclusion criteria consist of the receipt of platinum-based chemotherapy in the metastatic setting and the availability of comprehensive genomic profiling using next-generation sequencing (NGS). Patients were included in the HRD-like group if demonstrated oncogenic or likely oncogenic alterations in HR-/DDR-genes. Clinical endpoints were compared between the HRD-like group and the non-HRD-like group. Results Seventy-four patients were included, of whom 25 (33%) in the HRD-like group and 49 (66%) in the non-HRD group. With a median follow-up of 26.04 months (interquartile-range [IQR] 9.41-29.27) in the HRD-like group and of 22.48 months (IQR 16.86-40.53) in the non-HRD group, no PFS difference emerged, with a mPFS of 5.18 months in the HRD-like group compared to 6.04 months in the non-HRD group (hazard ratio [HR], 1.017, 95% CI 0.58-1.78; P  = .95). No differences were observed in DCR (64% [95 CI 45%-83%] vs 73% [95 CI 61%-86%]; P  = .4), and CBR (45% [95% CI 28%-73%] vs 50% [95% CI, 37%-68%]; P  = .9) between the HRD-like group and non-HRD groups, respectively. Median OS did not statistically differ between the HRD-like group and non-HRD group (26.7 vs 18.0 months, respectively; HR, 0.670, 0.33 to 1.37, P  = .27). Conclusion HR-/DDR-genes, when assessed with regular tumor-only NGS panels, provide limited clinical validity to identify patients with BTC more likely to benefit from platinum-based chemotherapy.

Background: Systemic inflammation is believed to contribute to small cell lung cancer (SCLC) progression, but the underlying relationship remains unclear. Lipocalin‐2, a potential biomarker of inflammation, has been implicated in various cancers but its prognostic value in SCLC is underexplored. Methods: We retrospectively analyzed 191 patients with SCLC (72 with limited‐stage [LD] and 119 with extensive‐stage) treated using platinum‐based chemotherapy. Lipocalin‐2 expression was evaluated using immunohistochemistry. Optimal cutoff values for lipocalin‐2 and neutrophil‐to‐lymphocyte ratio (NLR) were determined using time‐dependent receiver operating characteristic curve analysis. The pectoralis muscle index was used to assess sarcopenia. Results: In LD‐SCLC, high lipocalin‐2 expression was associated with worse progression‐free survival (PFS; median: 7.0 vs. 15.9 months, p = 0.015) and overall survival (OS; median: 12.9 vs. 30.3 months, p = 0.035) compared with low lipocalin‐2 expression. Patients were stratified into three prognostic groups by combining lipocalin‐2 with NLR: low lipocalin‐2/low NLR, high lipocalin‐2/low NLR or low lipocalin‐2/high NLR, and high lipocalin‐2/high NLR (median PFS: 17.3 vs. 11.0 vs. 6.3 months, p = 0.004; median OS: 30.5 vs. 17.3 vs. 8.6 months, p = 0.002). Similar trends were observed when combining lipocalin‐2 with the pectoralis muscle index. High lipocalin‐2 expression was also associated with lower complete response rates (18.9% vs. 34.3%, p = 0.035). No significant prognostic implications were found for lipocalin‐2 in extensive‐stage SCLC. Conclusions: High lipocalin‐2 expression is potentially associated with poorer survival in LD‐SCLC. Combining lipocalin‐2 with other inflammation‐related markers could improve prognostic stratification. [ABSTRACT FROM AUTHOR]

INTRODUCTION: The results of the phase 3 ALSYMPCA trial showed that Radium-223 (Ra-223) improves overall survival (OS) and delays onset of first symptomatic skeletal event vs. placebo in patients with metastatic castration-resistant prostate cancer (mCRPC). The purpose of the REACTIVATE study was to inform the optimal placement of Ra-233 in the treatment sequence by evaluating clinical outcomes and healthcare resource utilization using real-world data from multiple Canadian provinces. METHODS: This retrospective cohort study analyzed patient outcomes according to Ra-223 placement using administrative databases of four Canadian provinces, encompassing 4301 patients with mCRPC who received at least two lines of life-prolonging therapy (LPT) for mCRPC. Outcomes included OS, event-free survival (EFS), and healthcare resource utilization. Each province was analyzed separately. RESULTS: OS, measured from the start of second-line LPT, differed between provinces: those in Ontario receiving second-line Ra-223 had a longer OS vs. those receiving it in third-line or later (hazard ratio [HR] 0.79, 95% confidence interval [CI] 0.66-0.95). There was no difference between lines of therapy in patients in British Columbia (HR 1.165, 95% CI, 0.894-1.518, p=0.2576), and OS was numerically worse but not statistically significant in patients receiving Ra-223 in second-line in Quebec (HR 1.44, 95% CI, 0.93-2.24). Other outcomes also varied across provinces, with second-line use of Ra-223 being associated with longer EFS and reduced healthcare utilization vs. third-line use in Ontario but not in Quebec. CONCLUSIONS: Significant heterogeneity exists in the management and outcomes of mCRPC between provinces, particularly regarding the placement of Ra-223 in the treatment sequence.

Simple Summary: Sacrectomy represents a radical indication for bone sarcomas (e.g., osteosarcoma or chondrosarcoma) and chordomas, as well as selected carcinomas with invasion of the sacrum. Extralesional en bloc excision is surgically demanding and associated with resection-induced neurologic deficits and risks. Due to the low incidence of bone sarcomas, the rare localization in the sacrum and the complexity of the surgical procedure, studies reporting on the oncological outcome and corresponding complications in larger patient numbers are rare. The aim was to describe the oncosurgical management and the complication profile and to analyze our own treatment results after partial/total sacrectomy, with attention paid to a possible benefit by using intraoperative 3D navigation. There was a significant difference in progression-free and metastasis-free survival between sarcoma, chordoma and carcinoma patients. Complications were common, but no independently influencing causative factors could be identified. Although there was a subjective impression of improved intraoperative 3D orientation and easier identification of resection planes, the use of navigation did not significantly influence resection status or oncological patient outcome. Introduction: Bone sarcoma or direct pelvic carcinoma invasion of the sacrum represent indications for partial or total sacrectomy. The aim was to describe the oncosurgical management and complication profile and to analyze our own outcome results following sacrectomy. Methods: In a retrospective analysis, 27 patients (n = 8/10/9 sarcoma/chordoma/locally recurrent rectal cancer (LRRC)) were included. There was total sacrectomy in 9 (incl. combined L5 en bloc spondylectomy in 2), partial in 10 and hemisacrectomy in 8 patients. In 12 patients, resection was navigation-assisted. For reconstruction, an omentoplasty, VRAM-flap or spinopelvic fixation was performed in 20, 10 and 13 patients, respectively. Results: With a median follow-up (FU) of 15 months, the FU rate was 93%. R0-resection was seen in 81.5% (no significant difference using navigation), and 81.5% of patients suffered from one or more minor-to-moderate complications (especially wound-healing disorders/infection). The median overall survival was 70 months. Local recurrence occurred in 20%, while 44% developed metastases and five patients died of disease. Conclusions: Resection of sacral tumors is challenging and associated with a high complication profile. Interdisciplinary cooperation with visceral/vascular and plastic surgery is essential. In chordoma patients, systemic tumor control is favorable compared to LRRC and sarcomas. Navigation offers gain in intraoperative orientation, even if there currently seems to be no oncological benefit. Complete surgical resection offers long-term survival to patients undergoing sacrectomy for a variety of complex diseases. [ABSTRACT FROM AUTHOR]

Background and objective Pulmonary sarcomatoid carcinoma (PSC) is a rare subtype of non-small cell lung cancer (NSCLC), which is featured by low incidence, high malignancy rate, robust aggressive behavior and inferior prognosis. To date, there is no standardized treatment. The aim of this study is to better understand and accumulate more clinical experience of the disease by summarizing the clinicopathological features, diagnosis methods, therapeutic regimen and prognostic factors of PSC. Methods A total of 39 patients with PSC who diagnosed and received treatment in Beijing Chest Hospital from December 2013 to December 2023 were retrospectively recruited, and information including demographic characteristics, clinicopathological features, tumor-node-metastasis (TNM) stage, diagnosis method and therapeutic regimen were carefully collected. Meanwhile, follow-up was conducted. Kaplan-Meier method was used to analyze the prognostic factors of the disease. Results The PSC patients in this study ranged in age from 45 to 76 years old, including 35 males and 4 females. There were no specific clinical manifestations of PSC at initial diagnosis. Among the 39 patients, 20 underwent surgical resection and 19 received palliative chemoradiation or symptomatic supportive treatment. The 1-year and 5-year survival rates were 61.90% and 35.20% respectively. Univariate analysis indicated that family history of carcinoma, primary tumor site, TNM stage, lymph node metastasis, distant metastasis, whether or not received surgical resection, surgical method, treatment regimens, tumor tissue programmed cell death ligand 1 (PD-L1) expression ≥1% and mesenchymal-epithelial transition factor (MET) pathway abnormalities were correlated with the overall survival (OS) of patients (P<0.05). In the subsequent multivariate analysis, lymph node metastasis emerged as the only independent prognosticator in predicting inferior OS (P=0.037). Conclusion PSC is rarely seen in clinical practice and commonly occurs in elder men with smoking history. Tumor tissue PD-L1 expression ≥1% and MET abnormalities may predict inferior prognosis of PSC and lymph node metastasis was determined as the independent prognosticator of PSC. Surgical resection along with adjuvant medical treatment is the cornerstone for early and locally advanced patients, and the clinical utility of molecular targeting therapy and immunotherapy in PSC needs to be further investigated.

Introduction: Medullary thyroid carcinoma (MTC) is a rare type of thyroid cancer and the main treatment is surgery. The extent of surgery depends on the spread of tumour and often involves thyroidectomy and neck dissection. Recurrent or metastasis tumour can be detected with raising calcitoninand there are various options of treatment. Methods: This was a retrospective study of MTC over seven years in a tertiary cancer centre which evaluated the treatment outcome and the non-surgical options available in recurrent and metastatic tumours. Results: Among the 601 thyroid cancers, 34 patients (5.3%) were MTC, of which 29 were studied. Majority were women, below 60 years, were diagnosed with fine needle aspiration cytology of thyroid nodule or nodes and had raised calcitonin value (Ctn). The value of Ctn was correlated with tumour burden rather than extent (p=0.7). Recurrence was seen in 35% and all patients with locoregional recurrence had curative surgery whereas metastatic patients were offered palliative treatment. Acceptance of palliative treatment was less due to financial burden. The five year overall survival for nonmetastatic disease was 89.4 % and for patients with metastatic disease at presentation was 54.7 %. Conclusion: The incidence of medullary thyroid carcinoma is low compared to the differentiated thyroid carcinoma. The main treatment is surgery and other treatment options are limited.

Purpose: Anatomical structures and organ preservation concepts of the head and neck are important for patients with locally advanced head and neck squamous cell carcinoma (LA HNSCC). Neoadjuvant chemotherapy has been applied to improve organ preservation; however, pathological complete remission is still unsatisfactory. The purpose of this study was to explore the pathological complete response (pCR) rate and safety of immune checkpoint blockade combined with neoadjuvant chemotherapy (NAC) in patients with LA HNSCC. Methods: Fifty-one patients participated in this retrospective study, and of these, 25 received NAC only (cisplatin+5-fluorouracil+nab-paclitaxel), and 26 received NAC (cisplatin+5-fluorouracil) plus pembrolizumab. Pathological complete remission, the objective response rate (ORR), delayed surgery and toxicity were compared between the two groups. Results: A significant difference was observed in the pCR rate and ORR between the NAC+ICB group and the NAC group. Delaying surgery and Grade 3 or 4 AEs occurred more frequently in the NAC group. In the NAC-only group, during a median follow-up period of 31.80 months, the recurrence-free survival (RFS) rate was 80.0%, the disease-free survival (DFS) rate was 80.0% and the overall survival (OS) rate was 88.0%. In the NAC+ICB group, during the median follow-up period of 22.99 months, the RFS rate was 96.2%, the DFS rate was 96.2% and the OS rate was 100%. Conclusion: The combination of pembrolizumab with NAC could improve the pathological response without increasing the risk of toxicity, which provides pathological evidence for the treatment of LA HNSCC patients with NAC+ICB.

Background: The aim of the present study was to evaluate the impact of intratumoral metabolic heterogeneity and quantitative 18F‐FDG PET/CT imaging parameters in predicting patient outcomes in thymic epithelial tumors (TETs). Methods: This retrospective study included 100 patients diagnosed with TETs who underwent pretreatment 18F‐FDG PET/CT. The maximum and mean standardized uptake values (SUVmax and SUVmean), metabolic tumor volume (MTV), and total lesion glycolysis (TLG) on PET/CT were measured. Heterogeneity index‐1 (HI‐1; standard deviation [SD] divided by SUVmean) and heterogeneity index‐2 (HI‐2; linear regression slopes of the MTV according with different SUV thresholds), were evaluated as heterogeneity indices. Associations between these parameters and patient survival outcomes were analyzed. Results: The univariate analysis showed that Masaoka stage, TNM stage, WHO classification, SUVmax, SUVmean, TLG, and HI‐1 were significant prognostic factors for progression‐free survival (PFS), while MTV, HI‐2, age, gender, presence of myasthenia gravis, and maximum tumor diameter were not. Subsequently, multivariate analyses showed that HI‐1 (p < 0.001) and TNM stage (p = 0.002) were independent prognostic factors for PFS. For the overall survival analysis, TNM stage, WHO classification, SUVmax, and HI‐1 were significant prognostic factors in the univariate analysis, while TNM stage remained an independent prognostic factor in multivariate analyses (p = 0.024). The Kaplan Meier survival analyses showed worse prognoses for patients with TNM stages III and IV and HI‐1 ≥ 0.16 compared to those with stages I and II and HI‐1 < 0.16 (log‐rank p < 0.001). Conclusion: HI‐1 and TNM stage were independent prognostic factors for progression‐free survival in TETs. HI‐1 generated from baseline 18F‐FDG PET/CT might be promising to identify patients with poor prognosis. [ABSTRACT FROM AUTHOR]

Objective: The treatment with 177Lutetium PSMA (177Lu-PSMA) in patients with metastatic castration-resistant prostate cancer (mCRPC) has recently been approved by the FDA and EMA. Since treatment success is highly variable between patients, the prediction of treatment response and identification of short- and long-term survivors after treatment could help tailor mCRPC diagnosis and treatment accordingly. The aim of this study is to investigate the value of radiomic parameters extracted from pretreatment 68Ga-PSMA PET images for the prediction of treatment response. Methods: A total of 45 mCRPC patients treated with 177Lu-PSMA-617 from two university hospital centers were retrospectively reviewed for this study. Radiomic features were extracted from the volumetric segmentations of metastases in the bone. A random forest model was trained and validated to predict treatment response based on age and conventionally used PET parameters, radiomic features and combinations thereof. Further, overall survival was predicted by using the identified radiomic signature and compared to a Cox regression model based on age and PET parameters. Results: The machine learning model based on a combined radiomic signature of three features and patient age achieved an AUC of 0.82 in 5-fold cross-validation and outperformed models based on age and PET parameters or radiomic features (AUC, 0.75 and 0.76, respectively). A Cox regression model based on this radiomic signature showed the best performance to predict overall survival (C-index, 0.67). Conclusion: Our results demonstrate that a machine learning model to predict response to 177Lu-PSMA treatment based on a combination of radiomics and patient age outperforms a model based on age and PET parameters. Moreover, the identified radiomic signature based on pretreatment 68Ga-PSMA PET images might be able to identify patients with an improved outcome and serve as a supportive tool in clinical decision making.

Simple Summary: In the present study, the intraoperative fluorescence of brain metastases after the administration of 5-aminolevulinic acid (5-ALA) is investigated in 80 cases. Brain metastases fluoresced in 57.5% of cases, with no significant correlation between fluorescence and primary tumor or histological subtype. Complete resection of brain metastases was detected in 82.5%, of which 56.1% were fluorescence positive, compared to 43.9% which were non-fluorescent. Thus, prior administration of 5-ALA tended to improve the resectability rate by 12.1%. Fluorescence-positive and -negative metastases showed significantly different overall survival in this study. Therefore, administration of 5-ALA as a surgical adjuvant may be beneficial in resecting brain metastases and may potentially optimize the surgical procedure. (1) Background: In this study, the intraoperative fluorescence behavior of brain metastases after the administration of 5-aminolevulinic acid (5-ALA) was analyzed. The aim was to investigate whether the resection of brain metastases using 5-ALA fluorescence also leads to a more complete resections and thus to a prolongation of survival; (2) Methods: The following variables have been considered: age, sex, number of metastases, localization, involvement of eloquent area, correlation between fluorescence and primary tumor/subtype, resection, and survival time. The influence on the degree of resection was determined with a control MRI within the first three postoperative days; (3) Results: Brain metastases fluoresced in 57.5% of cases. The highest fluorescence rates of 73.3% were found in breast carcinoma metastases and the histologic subtype adenocarcinoma (68.1%). No correlation between fluorescence behavior and localization, primary tumor, or histological subtype was found. Complete resection was detected in 82.5%, of which 56.1% were fluorescence positive. There was a trend towards improved resectability (increase of 12.1%) and a significantly longer survival time (p = 0.009) in the fluorescence-positive group; (4) Conclusions: 5-ALA-assisted extirpation leads to a more complete resection and longer survival and can therefore represent a low-risk addition to modern surgery for brain metastases.

Simple Summary: The aim of this study was to evaluate 18 different preoperative immune, inflammatory, and nutritional scores and their best cut-off values as predictors of poorer overall survival (OS) and disease-free survival (DFS) in patients who underwent curative gastrectomy for gastric adenocarcinoma. This is a retrospective observational multicentre study based on data of the Spanish EURECCA Esophagogastric Cancer Registry. Time-dependent Youden index and log-rank test were used to obtain the best cut-offs of preoperative biomarkers for OS and DFS. The most relevant preoperative biomarkers of poorer OS and DFS were high neutrophil-to-lymphocyte ratio (NLR), high monocyte systemic inflammation index (moSII) (for stages I and III), and low prognostic nutritional index (PNI) (regardless tumour stage). Background: The aim of this study was to evaluate different preoperative immune, inflammatory, and nutritional scores and their best cut-off values as predictors of poorer overall survival (OS) and disease-free survival (DFS) in patients who underwent curative gastric cancer resection. Methods: This was a retrospective observational multicentre study based on data of the Spanish EURECCA Esophagogastric Cancer Registry. Time-dependent Youden index and log-rank test were used to obtain the best cut-offs of 18 preoperative biomarkers for OS and DFS. An adjusted Cox model with variables selected by bootstrapping was used to identify the best preoperative biomarkers, which were also analysed for every TNM stage. Results: High neutrophil-to-lymphocyte ratio (NLR), high monocyte systemic inflammation index (moSII), and low prognostic nutritional index (PNI) were identified as independent predictors of poor outcome: NLR > 5.91 (HR:1.73; 95%CI [1.23–2.43]), moSII >2027.12 (HR:2.26; 95%CI [1.36–3.78]), and PNI >40.31 (HR:0.75; 95%CI [0.58–0.96]) for 5-year OS and NLR > 6.81 (HR:1.75; 95%CI [1.24–2.45]), moSII > 2027.12 (HR:2.46; 95%CI [1.49–4.04]), and PNI > 40.31 (HR:0.77; 95%CI [0.60,0.97]) for 5-year DFS. These outcomes were maintained in the whole cohort for NLR and moSII (p < 0.05) but not in stage II and for PNI in all tumoral stages. The associations of NLR-PNI and moSII-PNI were also a relevant prognostic factor for OS. Conclusions: High NLR, high moSII (for stages I and III), and low PNI (regardless of tumour stage) were the most promising preoperative biomarkers to predict poor OS and DFS in gastric cancer patients treated with curative intent.

Simple Summary: Lazertinib, a third-generation EGFR-TKI, selectively inhibits both the common EGFR mutation and the T790M mutation in NSCLC patients. No previous studies have compared lazertinib with platinum-based chemotherapy. In this external control retrospective study, we have compared the efficacy of lazertinib and platinum-based chemotherapy in patients who had previously received EGFR-TKI treatment. This study included 200 patients from the LASER 201, LASER 301, and LASER-PMS studies, and 334 patients who received platinum-based chemotherapy after prior EGFR-TKI treatment for SMC. After propensity score matching, we selected 156 patients from each group. The PFS was significantly longer in those patients treated with lazertinib than in those treated with platinum-based chemotherapy (10.97 months vs. 5.10 months) after PSM. Lazertinib also demonstrated superior OS, ORR, and TTD compared to platinum-based chemotherapy. Based on this retrospective, external control study, lazertinib demonstrated significantly superior efficacy compared to platinum-based chemotherapy. The external controls provide important context to evaluate efficacy in single-arm studies. Background: Lazertinib is a third-generation tyrosine kinase inhibitor of epidermal growth factor receptor (EGFR-TKI) that selectively inhibit common EGFR mutation and T790M mutation in non-small-cell lung cancer (NSCLC) patients. No previous studies have compared lazertinib to platinum-based chemotherapy. We have compared lazertinib with platinum-based chemotherapy in EGFR-mutated NSCLC patients after previous EGFR-TKI therapy. Methods: We retrospectively compared 200 patients from LASER201, LASER301, and LASER-PMS studies to 334 patients who were treated with platinum-based chemotherapy after previous EGFR-TKI from the Samsung Medical Center. After propensity score matching (PSM), we selected 156 patients from each group. The primary outcome was progression-free survival (PFS), with overall survival (OS), objective response rate (ORR), and time to treatment discontinuation (TTD) as secondary outcomes. Results: The median follow-up of PFS was 15.61 months in the lazertinib group and 21.67 months in the external control group. The PFS was significantly longer in patients who were treated with lazertinib than those treated with platinum-based chemotherapy (10.97 months vs. 5.10 months; adjusted hazard ratio (HR) 0.40; 95% confidence interval (CI), 0.29–0.55; p < 0.01) after PSM. Lazertinib showed superior OS (32.23 months vs. 18.73 months; adjusted HR 0.45; 95% CI, 0.29–0.69; p < 0.001), ORR (64.1% vs. 47.4%), and TTD (11.66 months vs. 6.73 months; adjusted HR 0.54; 95% CI, 0.39–0.75; p < 0.001) compared to platinum-based chemotherapy. Conclusion: Based on this retrospective, external control study, lazertinib has demonstrated significantly better efficacy compared with platinum-based chemotherapy. The external controls provide important context to evaluate efficacy in single-arm studies. [ABSTRACT FROM AUTHOR]

Simple Summary: Immunotherapy or combined chemoimmunotherapy is currently first-line therapy for patients with metastatic NSCLC without a driver mutation. Despite immunotherapy contributing to improved survival outcomes, the estimated 5-year OS rate for metastatic NSCLC remains poor. The aim of our retrospective study was to assess how patients with different anatomical metastatic sites respond or develop resistance to immunotherapy, combination chemoimmunotherapy, or chemotherapy alone. We confirmed that patients with bone metastases have poorer survival outcomes compared to those without bone metastases. This highlights a group of patients that may benefit from a specific clinical trial evaluation to assess the benefit of additional novel therapeutics or upfront radiotherapy. Patients with advanced NSCLC have heterogenous responses to immune checkpoint inhibitors (ICIs) with or without chemotherapy. In NSCLC, the impact of the distribution of metastatic sites and the response to systemic therapy combinations remain poorly understood. In a retrospective cohort study of patients with unresectable stage III/IV NSCLC who received first-line systemic therapy, we sought to assess the association between the site of metastases with patterns of response and progression. Data regarding demographics, tumour characteristics (including site, size, and volume of metastases), treatment, and outcomes were examined at two cancer care centres. The endpoints included organ site-specific response rate, objective response rate (ORR), progression-free survival (PFS), and overall survival (OS). Two-hundred and eighty-five patients were included in the analysis. In a multivariate analysis, patients with bone metastases had a reduced ORR, PFS, and OS. Primary resistance was also more likely in patients with bone metastases. Patients with bone or liver metastases had a shorter OS when receiving ICIs with or without chemotherapy, but not with chemotherapy alone, suggesting an immunological basis for therapeutic resistance. A directed assessment of the tumour microenvironment in these locations and a deeper understanding of the drivers of organ-specific resistance to immunotherapy are critical to optimise novel combination therapies and sequencing in these patients.

Simple Summary: The optimal radiotherapy (RT) dose for tracheobronchial adenoid cystic carcinoma (ACC) remains unclear due to its scarcity. This retrospective study evaluated the efficacy of dose-escalated RT for primary tracheobronchial ACC by dividing patients into groups of either low (<70.0 Gy EQD2) or high (≥70.0 Gy EQD2) RT doses. In the definitive RT group, the high-dose group showed better local control and survival rates compared to the low-dose group. The treatment related toxicities were the trachea or main bronchus stenosis. Dose-escalated RT may be effective for the definitive treatment of tracheobronchial ACC. Primary tracheobronchial adenoid cystic carcinoma (ACC) is a rare malignancy, so the optimal radiotherapy (RT) dose remains unestablished. We aimed to evaluate the effectiveness of dose-escalated RT for primary tracheobronchial ACC. We retrospectively reviewed 48 patients who had undergone definitive or postoperative RT. Patients classified into the low- and high-dose groups received RT doses <70.0 and ≥70.0 Gy in EQD2, respectively. The primary endpoint was freedom from local progression (FFLP) and overall survival (OS). Throughout the follow-up period, seven patients (14.6%) experienced local progression, while 31 (64.6%) exhibited distant metastasis, most commonly in the lungs. In total, the 5-year FFLP and OS rates were 85.7 and 84.7%, respectively. Multivariate analysis revealed that regional lymph node metastasis at diagnosis and receipt of definitive RT were associated with poorer OS. In the subgroup analysis, the definitive RT group had a 5-year FFLP rate of 33.3 and 78.2% in the low- and high-dose groups (p = 0.065), whereas 5-year OS rates were 66.7 and 79.0%, respectively (p = 0.022). Four patients (8.3%) experienced Grade 3 toxicity with tracheal or main bronchus stenosis. Dose-escalated RT with conventional fractionation may be effective in patients with tracheobronchial ACC, especially for a definitive aim. [ABSTRACT FROM AUTHOR]
