In oncology anti-PD1 / PDL1 therapy development for solid tumors, objective response rate (ORR) is commonly used clinical endpoint for early phase study decision making, while progression free survival (PFS) and overall survival (OS) are widely used for late phase study decision making. Developing predictive models to late phase outcomes such as median PFS (mPFS) and median OS (mOS) based on early phase clinical outcome ORR could inform late phase study design optimization and probability of success (POS) evaluation. In existing literature, there are ORR / mPFS / mOS association and surrogacy investigations with limited number of included clinical trials. In this paper, without establishing surrogacy, we attempt to predict late phase survival (mPFS and mOS) based on early efficacy ORR and optimize late phase trial design for anti-PD1 / PDL1 therapy development. In order to include adequate number of eligible clinical trials, we built a comprehensive quantitative clinical trial landscape database (QLD) by combining information from different sources such as clinicaltrial.gov, publications, company press releases for relevant indications and therapies. We developed a generalizable algorithm to systematically extract structured data for scientific accuracy and completeness. Finally, more than 150 late phase clinical trials were identified for ORR / mPFS (ORR / mOS) predictive model development while existing literature included at most 50 trials. A tree-based machine learning regression model has been derived to account for ORR / mPFS (ORR / mOS) relationship heterogeneity across tumor type, stage, line of therapy, treatment class and borrow strength simultaneously when homogeneity persists. The proposed method ensures that the predictive model is robust and have explicit structure for clinical interpretation. Through cross validation, the average predictive mean square error of the proposed model is competitive to random forest and extreme gradient boosting methods and outperforms commonly used additive or interaction linear regression models. An example application of the proposed ORR / mPFS (ORR / mOS) predictive model on late phase trial POS evaluation for anti-PD1 / PDL1 combination therapy was illustrated., (© 2024. The Author(s).)

Background/aim: Many patients with glioblastoma experience an intracerebral recurrence and require a personalized treatment. This study aimed to facilitate this approach by identifying prognostic factors for progression-free survival (PFS) and overall survival (OS)., Patients and Methods: In 102 patients with recurrent glioblastoma following primary treatment with resection or biopsy plus adjuvant chemoradiation, 11 characteristics were retrospectively investigated regarding PFS and OS., Results: In the multivariate analyses, Karnofsky performance score (KPS) 90-100 at the time of recurrence (p=0.032), maximum cumulative diameter of recurrent lesions ≤40 mm (p=0.002), resection of recurrent glioblastoma (p=0.025), and systemic therapy for recurrent glioblastoma (p=0.025) were significantly associated with improved PFS. In addition, KPS 90-100 (p=0.024), maximum cumulative diameter ≤40 mm (p=0.033), and systemic therapy (p=0.006) were significantly associated with better OS., Conclusion: Our study identified high Karnofsky Performance Status (KPS 90-100), maximum cumulative diameter of recurrent glioblastoma lesions ≤40 mm, and systemic therapy for recurrent glioblastoma as independent predictors of overall survival (OS) and progression-free survival (PFS). These independent prognostic factors may help select the most suitable treatment for individual patients with recurrent glioblastoma, potentially improving patient outcomes., (Copyright © 2024 International Institute of Anticancer Research (Dr. George J.

Objectives: The goal of the research was to assess the quantitative relationship between median progression-free survival (PFS) and median overall survival (OS) specifically among patients with relapsed/refractory multiple myeloma (RRMM) based on published randomized controlled trials (RCTs)., Methods: Two bibliographic databases (PubMed and Embase, 1970-2017) were systematically searched for RCTs in RRMM that reported OS and PFS, followed by an updated search of studies published between 2010 and 2022 in 3 databases (Embase, MEDLINE, and EBM Reviews, 2010-2022). The association between median PFS and median OS was assessed using the nonparametric Spearman rank and parametric Pearson correlation coefficients. Subsequently, the quantitative relationship between PFS and OS was assessed using weighted least-squares regression adjusted for covariates including age, sex, and publication year. Study arms were weighted by the number of patients in each arm., Results: A total of 31 RCTs (56 treatment arms, 10,450 patients with RRMM) were included in the analysis. The average median PFS and median OS were 7.1 months (SD 5.5) and 28.1 months (SD 11.8), respectively. The Spearman and Pearson correlation coefficients between median PFS and median OS were 0.80 (P < 0.0001) and 0.79 (P < 0.0001), respectively. In individual treatment arms of RRMM trials, each 1-month increase in median PFS was associated with a 1.72-month (95% CI 1.26-2.17) increase in median OS., Conclusion: Analysis of the relationship between PFS and OS incorporating more recent studies in RRMM further substantiates the use of PFS to predict OS in RRMM., (© 2024.

T cell lymphoblastic lymphoma (T-LBL) has an aggressive clinical behavior. To date, powerful and consistent prognostic factors have not been established for T-LBL. In this study, we first evaluated the association of event-free survival (EFS) at 24 months (EFS24) with overall survival (OS) in T-LBL patients. Besides, we sought to identify clinical factors of prognostic importance in this rare entity. Between January 2006 and December 2017, ninety-one patients with newly diagnosed T-LBL were retrospectively analyzed. EFS was defined as the time from diagnosis to relapse or progression, unplanned retreatment, death from any cause, or to the last follow-up. In total, 91 patients with a median age of 24 years were enrolled. At a median follow-up of 40.4 months (range, 1.4 to 163.3 months), the 5-year OS and EFS was 47.9% and 43.2%, respectively. Of all patients, 45 (49.5%) achieved EFS24 and 46 (50.5%) did not. Patients who achieved EFS24 showed a markedly superior outcome, compared with those who failed to achieve EFS24 (5-year OS, 90.5% vs 3%, P < 0.001). Univariate analysis indicated bone marrow involvement, response to induction treatment, and stem cell transplantation (SCT) consolidation to be prognostic factors for EFS and OS. In addition, compared with the patients receiving non-Hodgkin's lymphoma (NHL)-like treatment protocols, patients treated with hyper-CVAD showed significantly improved EFS and OS. Such survival advantage in terms of EFS and OS was also observed of BMF-90 regimens over NHL-like therapy, despite that the difference in EFS did not reach statistical significance (P = 0.056). Multivariate analysis demonstrated that achievement of complete remission (CR) after induction therapy and SCT consolidation were independent prognostic indicators for both EFS and OS. We confirm that EFS24 is a strong surrogate endpoint for long-term survival in T-LBL, which is clinically useful for individualized risk reassessment, future clinical trial design, and biomarker discovery validation. Further validation in the context of directed prospective clinical trials is warranted.

Background: Ki-67 proliferation index is widely used for differentiating between high and low-grade gliomas, but differentiating between the same grade IV appears to be more problematic, and the point about its prognostic value for GBM patients remains unclear. To reduce the possibility to find a marked histological heterogeneity, and may contain areas that could be diagnosed as lower grade, in this study we considered a large group of patients with IDH wild-type Glioblastoma (IDH-WT GBM) and we have analyzed previously reported prognostic factors, in regards to their relationship with the Ki-67 expression index., Methods: We explore the prognostic impact of ki-67 index status in 127 patients affected by IDH-WT GBM. We therefore analyzed clinical characteristics, tumor genetics, dimension and clinical outcomes. We selected a total of 127 patients affected by newly diagnosed IDH-WT GBM who underwent surgery, radiation, and chemotherapy in our Institution in the period ranging between January 2014 and December 2016 RESULTS: The volume of the lesion had a strong association with the Ki67 overexpression. In particular lesions whose volume was greater than 45  cm 3 , presented a higher percentage of Ki67 expression demonstrating that greater tumors are more likely associated to higher values of Ki67 percentages. On a multivariate analysis, it was possible to outline that Ki67 was significant a predictor of shorter PFS independently from the age of the patients, the volume of the lesion and preoperative KPS., Conclusions: There is a correlation between percentage staining of Ki-67 and OS in our cohort of patients with IDH-WT GBM. This is only the third observational study documenting a positive correlation between Ki-67 and overall survival in GBM and the first one demonstrates that percentage Ki-67 staining >20 % predicts poorer progression free survival in IDH-WT GBM., (Published by Elsevier B.V.)

Advances in the management of multiple myeloma (MM) have led to a significant prolongation of both progression-free (PFS) and overall survival (OS). Herein, we evaluated the characteristics of patients who achieved a PFS of at least 7 years following frontline therapy, as compared with all other patients who were treated in a single center during the same time period. Thirty-six (8.8%) patients achieved a PFS of at least 7 years (long PFS group) after frontline treatment. Long PFS patients were younger (p < 0.001) and had lower ECOG performance status (p = 0.014), higher hemoglobin (p = 0.001), and higher creatinine clearance (p < 0.001) compared with the others. More patients in the long PFS group had ISS-1 or ISS-2 disease (p = 0.002) and normal pattern of marrow infiltration (p = 0.035). No patient in the long PFS group had high-risk cytogenetics at diagnosis. Long PFS patients had received more often autologous stem cell transplantation (p = 0.001) and had achieved deeper responses. The probability of achieving long PFS (≥ 7 years) for patients who managed to be progression-free at 2, 3, and 4 years was 11.6%, 13.2%, and 15.3%, respectively. Median OS in the long PFS group has not been reached yet, while in all other patients, the median OS was 4.3 years. In conclusion, our study in an unselected patient group showed that 9% of patients with newly diagnosed myeloma experience prolonged PFS of more than 7 years in the era of conventional chemotherapy or first-generation novel agents. We anticipate that novel treatment approaches will increase the probability of achieving a prolonged relapse-free status.

Purpose: Earlier studies suggest progression-free survival (PFS) may be used as a surrogate endpoint for overall survival (OS) in metastatic breast cancer, which could shorten follow-up duration and speed up assessment of treatment effects. However, to our knowledge, the association between them is still unclear in advanced or metastatic triple-negative breast cancer (TNBC)., Methods: A literature-based meta-analysis followed by correlation analysis was conducted in advanced or metastatic TNBC. Weighted multiple regression analysis was then used to test the strength of the association between medians of PFS and OS, and the association between HR PFS and HR OS ., Results: Fourteen randomized clinical trials published between January 2007 and August 2019, 31 median pairs for PFS and OS, and 17 pairs for HR PFS and HR OS from 3,880 patients were selected. The Pearson correlation coefficient between medians of PFS and OS was 0.84 (95% confidence interval (CI) 0.68-0.92, p < 0.001), and the correlation coefficient between HR PFS and HR OS was 0.86 (95% CI 0.63-0.95, p < 0.001). Weighted multiple regression analysis showed HR PFS was the most significant predictor of HR OS among covariates analyzed (p < 0.001). Both the medians of PFS and OS correlation, and the HR PFS and HR OS correlation were 0.79 (p < 0.001), 0.80 (p = 0.001), respectively, in the 11 trials excluding immunotherapy and bevacizumab-based therapy trials., Conclusions: Our analysis suggests PFS can be strongly correlated with OS and considered a valid surrogate endpoint for OS in advanced or metastatic TNBC.

Introduction: Complex underlying risk functions associated with immuno-oncology treatments have led to exploration of different methods (parametric survival, spline, landmark, and cure-fraction models) to estimate long-term survival outcomes. The objective of this study was to examine differences in estimated short- and long-term survival in previously treated metastatic Merkel cell carcinoma (mMCC) patients receiving avelumab, when using alternative extrapolation approaches., Methods: Efficacy data from the phase 2 JAVELIN Merkel 200 trial (part A) with at least 12 months of follow-up were analyzed. Standard parametric survival analyses and analyses of overall survival (OS) as a function of surrogate outcomes comprised of response (landmark analyses) and progression-free survival plus post-progression survival (PFS + PPS) were used to project OS. Overall survival throughout lifetime was projected and compared with the observed OS data with at least 24 months of follow-up., Results: Estimated OS from all three approaches provided a good fit to the observed OS curve from at least 12 months of follow-up. However, performance compared with OS data from at least 24 months showed that the landmark approach followed by PFS + PPS provided a better fit to the data as compared to standard parametric analysis. Mean life expectancy estimated with avelumab was 2.48 years with best-fitting parametric function (a log-normal distribution), 3.15 years with the landmark approach, and 3.54 years with PFS + PPS., Conclusion: Although standard parametric survival analysis may provide a good fit to short-term survival, it appears to underestimate the long-term survival benefits associated with avelumab in mMCC. Extrapolations based on surrogate outcomes of response or progression predict OS outcomes from longer follow-up better and appear to provide more clinically plausible projections., Funding: EMD Serono Inc, Rockland, MA, a business of Merck KGaA, Darmstadt, Germany.

Background and Purpose: Glioblastoma, WHO grade IV is the most frequent primary malignant brain tumor in adults. There are few articles and result about the efficacy of bevacizumab monotherapy. The aim of our paper is to examine the effect of bevacizumab therapy on progression free and overall survival in an extended database of recurrent glioblastoma patients., Methods: In our retrospective study, patients with recurrent glioblastoma treated with bevacizumab had been collected. All of our patients received first line chemo-irradiation according the Stupp protocol treatment. The histological diagnosis was primary or secondary glioblastoma in every patient. The prognostic features of primary and secondary glioblastomas were statistically analyzed., Results: Eighty-six patients were selected into the retrospective analysis. The histological diagnosis was primary glioblastoma in 65 patients (75.6%) and secondary glioblastoma in 21 patients (24.4%). The mean follow up period was 36.5 months. The mean second progression free survival beside bevacizumab therapy was 6.59 months and the mean overall survival was 24.55 months. In secunder glioblastoma cases, the mean second progression free survival was 6.16 months and the mean overall survival was 91.94 months., Conclusion: The bevacizumab therapy is a safe option in recurrent glioblastoma patients. Bevacizumab therapy has a positive effect both on progression free and overall survival and our results confirm the findings in the literature. There is no statistically significant difference in the second progression free survival between glioblastoma subtypes.

This paper considers methods for estimating the association between progression-free and overall survival in oncology trials. Copula-based, nonparametric, and illness-death model-based methods are reviewed. In addition, the approach based on an underlying illness-death model is generalized to allow general parametric models. The performance of these methods, in terms of bias and efficiency, is investigated through simulation and also illustrated using data from a clinical trial of treatments for colon cancer. The simulations suggest that the illness-death model-based method provides good estimates of Kendall's τ across several scenarios. In some situations, copula-based methods perform well but their performance is sensitive to the choice of copula. The Clayton copula is most appropriate in scenarios, which might realistically reflect an oncology trial, but the use of copula models in practice is questionable., (© 2018 The Authors.

Background: The purpose of this comprehensive meta-analysis was to assess the association of aldehyde dehydrogenase (ALDH) expression with overall survival (OS) and disease-free survival (DFS)/progression-free survival (PFS) in ovarian cancer patients., Methods: Systematic searches of Pubmed databases was performed to identify relevant literature published before February 28, 2018. A total of 14 studies (13 articles) with 2210 ovarian cancer patients were pooled. All included studies were performed by using Immunohistochemistry (IHC) for detection of ALDH expression. Hazard ratio (HR) and 95% confidence interval (CI) were extracted from included studies to evaluate the correlation of ALDH expression with OS and DFS/PFS., Results: High expression of ALDH was associated with worse OS (HR: 1.43; 95% CI: 1.18-1.73) and poor DFS/PFS (HR: 1.55, 95% CI: 1.12-2.14). No evidence of publication bias was observed in OS (Begg's test, P = 0.113; Egger's test, P = 0.355) and DFS/PFS (Begg's test, P = 0.655; Egger's test, P = 0.189) in ovarian cancer patients. The subgroup of studies with cut-off value of low expression showed that high expression of ALDH was correlated with poor OS (HR: 1.36; 95% CI: 1.14-1.62) and DFS/PFS (HR: 1.79; 95% CI: 1.45-2.20) in ovarian cancer patients, with no observed heterogeneity (OS: I 2  = 0%, P = 0.45; DFS/PFS: I 2  = 0%, P = 0.55)., Conclusion: In conclusion, high expression of ALDH is correlated with worse survival profiles in ovarian cancer patients, indicating that ALDH might act as a potential molecular biomarker for prognosis of ovarian cancer.

The selection of progression-free survival (PFS) or overall survival (OS) as the most suitable primary endpoint (PE) in oncology Phase 3 trials is currently under intense debate. Because of substantial limitations in the single use of PFS (or OS) as the PE, trial designs that include PFS and OS as co-primary endpoints are attracting increasing interest. In this article, we report on the formulation of determining the sample size for a trial that sequentially tests PFS and OS by treating them as co-PEs. Using a three-component model of OS, the proposed method overcomes the drawbacks of an existing method that requires unreasonable assumption of the exponential distribution for OS, although the hazard function is nonconstant because effective subsequent therapy has prolonged postprogression survival in recent oncology trials. Alternative estimation method of hazard ratio for OS under a three-component mode is also discussed by checking the appropriateness of assuming proportionality of hazards for OS. In order to examine the performance of our proposed method, we performed three numerical studies using both simulated and actual data of cancer Phase 3 trials. We find that the proposed method preserves a prespecified target value of power with a feasible increment of trial scale.

Background: Circulating cytokines can represent non-invasive biomarkers to improve prediction of clinical outcomes of cancer patients. Here, plasma levels of IL-8, CCL4, osteopontin, LIF and BDNF were determined at baseline (T0), after 2 months of therapy (T2) and, when feasible, at progression (TP), in 70 melanoma patients treated with BRAF and MEK inhibitors. The association of baseline cytokine levels with clinical response, progression-free survival (PFS) and overall survival (OS) was evaluated. Methods: Cytokine concentrations were measured using the xMAP technology. Their ability to discriminate between responding (Rs) and non-responding (NRs) patients was assessed by Receiver Operating Characteristics analysis. PFS and OS were estimated with the Kaplan–Meier method. The Cox proportional hazard model was used in the univariate and multivariate analyses to estimate crude and adjusted hazard ratios with 95% confidence intervals. Results: CCL4 and LIF were undetectable in the majority of samples. The median osteopontin concentration at T0 and T2 was significantly higher in NRs than in Rs. The median T0 and T2 values of IL-8 were also higher in NRs than in Rs, although the statistical significance was not reached. No differences were detected for BDNF. In 39 Rs with matched T0, T2, and TP samples, osteopontin and IL-8 significantly decreased from T0 to T2 and rose again at TP, while BDNF levels remained unchanged. In NRs, none of the cytokines showed a significant decrease at T2. Only osteopontin demonstrated a good ability to discriminate between Rs and NRs. A high IL-8 T0 level was associated with significantly shorter PFS and OS and higher risk of progression and mortality, and remained an independent negative prognostic factor for OS in multivariate analysis. An elevated osteopontin T0 concentration was also significantly associated with worse OS and increased risk of death. Patients with high IL-8 and high osteopontin showed the lowest PFS and OS, and in multivariate analysis this cytokine combination remained independently associated with a three- to six-fold increased risk of mortality. Conclusion: Circulating IL-8 and osteopontin appear useful biomarkers to refine prognosis evaluation of patients undergoing targeted therapy, and deserve attention as potential targets to improve its clinical efficacy.

Background: Usage of immune checkpoint inhibitors (ICIs) has prolonged the overall survival (OS) of patients with extensive‐stage small‐cell lung cancer (ES‐SCLC). In clinical trials, males accounted for a large proportion, leading to the uncertainty of its efficacy in female patients. We therefore conducted this study to explore the efficacy and safety of using ICIs in female patients with ES‐SCLC. Methods: We retrospectively enrolled female SCLC patients and subdivided them into two groups. Group A (n = 40) was defined as ES‐SCLC patients who received first‐line standard chemotherapy with or without ICIs. Group B (n = 47) included relapsed SCLC patients who were administered with second‐line therapies. Kaplan–Meier methodology was used to calculate survival analysis. Chi‐squared tests were used to analyze the incidence of adverse events (AEs). Results: Median progression‐free survival (PFS) and median OS favored the ICI‐contained cohorts (Group A PFS: 8.3 vs. 6.1 months; OS: not reached vs. 11.3 months; Group B PFS: 15.1 vs. 3.3 months; OS: 35.3 vs. 8.3 months), especially in those patients who received second‐line immunotherapies. Patients who received immunotherapy had a slightly higher incidence rate of grade ≥3 AEs (Group A: 71.4% vs. 46.2%; Group B: 44.5% vs. 13.2%). Those who developed grade ≥3 AEs in first‐line ICIs cohort had a more favorable survival (PFS: 8.3 vs. 3.2 months; OS: not reached vs. 5.1 months). Conclusions: Our study suggested that female ES‐SCLC patients treated with immunotherapy tended to achieve a relatively longer survival. The incidence of AEs (grade ≥3) was higher in women patients receiving ICIs, which requires monitoring more closely. [ABSTRACT FROM AUTHOR]

Purpose: Aim of this study is to investigate the association between DM and oncological outcomes among patients with muscle-invasive (MI) or high-risk non-muscle invasive (NMI) bladder cancer (BC) who underwent robot-assisted radical cystectomy with intracorporeal urinary diversion (RARC). Methods: An IRB approved multi-institutional BC database was queried, including patients underwent RARC between January 2013 and June 2023. Patients were divided into two groups according to DM status. Baseline, clinical, perioperative, pathologic data were compared. Chi-square and Student t tests were performed to compare categorical and continuous variables, respectively. Kaplan-Meier method and Cox regression analyses were performed to assess the association between DM and oncologic outcomes. Results: Out of 547 consecutive patients, 97 (17.7%) had DM. The two cohorts showed similar preoperative features, except for ASA score (p = 0.01) and Hypertension rates (p < 0.001). No differences were detected for perioperative complications, pT stage, pN stages and surgical margins status (all p > 0.12). DM patients displayed significantly lower 5-yr disease-free survival (DFS) (44.6% vs. 63.3%, p = 0.007), 5-yr cancer-specific survival (CSS) (45.1% vs. 70.1%, p = 0.001) and 5-yr Overall survival (OS) (39.9% vs. 63.8%, p = 0.001). At Multivariable Cox-regression analyses DM status was identified as independent predictor of worse cancer-specific survival (CSS) (HR 2.1; p = 0.001) and overall survival (OS) (HR 2.05; p < 0.001). Conclusion: Among BC patients who underwent RARC, DM patients showed worse oncologic outcomes than the non-DM patients, with DM status playing an independent negative predicting role in CSS and OS. Future prospective studies are awaited, stimulating basic and translational research to identify possible mechanisms of interaction between DM and BC. [ABSTRACT FROM AUTHOR]

Background: Autologous stem cell transplantation (ASCT) is a pivotal treatment for lymphoma patients. The BeEAM regimen (Bendamustine, Etoposide, Cytarabine, Melphalan) traditionally relies on cryopreservation, whereas the CEM regimen (Carboplatin, Etoposide, Melphalan) has been optimized for short-duration administration without the need for cryopreservation. This study rigorously compares the clinical and safety profiles of the BeEAM and CEM regimens. Methods: A controlled, randomized clinical trial was conducted with 58 lymphoma patients undergoing ASCT at the International Medical Center (IMC) in Cairo, Egypt. Patients were randomly assigned to either the BeEAM (n = 29) or CEM (n = 29) regimen, with an 18-month follow-up period. Clinical and safety outcomes were meticulously compared, focusing on time to engraftment for neutrophils and platelets, side effects, length of hospitalization, transplant-related mortality (TRM), and survival rates. Results: The findings demonstrate a significant advantage for the CEM regimen. Neutrophil recovery was markedly faster in the CEM group, averaging 8.5 days compared to 14.5 days in the BeEAM group (p < 0.0001). Platelet recovery was similarly expedited, with 11 days in the CEM group versus 23 days in the BeEAM group (p < 0.0001). Hospitalization duration was substantially shorter for CEM patients, averaging 18.5 days compared to 30 days for those on BeEAM (p < 0.0001). Furthermore, overall survival (OS) was significantly higher in the CEM group at 96.55% (95% CI: 84.91–99.44%) compared to 79.31% (95% CI: 63.11–89.75%) in the BeEAM group (p = 0.049). Progression-free survival (PFS) was also notably superior in the CEM group, at 86.21% (95% CI: 86.14–86.28%) versus 62.07% (95% CI: 61.94–62.20%) in the BeEAM group (p = 0.036). Conclusion: The CEM regimen might demonstrate superiority over the BeEAM regimen, with faster neutrophil and platelet recovery, reduced hospitalization time, and significantly improved overall and progression-free survival rates. Future studies with longer duration and larger sample sizes are warranted. Trial registration: This study is registered on ClinicalTrials.gov under the registration number NCT05813132 (https://clinicaltrials.gov/ct2/show/NCT05813132).

Thymic carcinoma (TC) is a rare malignant tumor with a poor prognosis, and there is currently limited data on the use of immunotherapy in patients with unresectable TC. In this study, data of patients with unresectable TC diagnosed from January 2017 were retrospectively collected from multiple centers. Treatment response, progression‐free survival (PFS), overall survival (OS), survival‐independent prognostic factor, and adverse events (AEs) were further analyzed. As a result, a total of 93 patients with unresectable TC were enrolled, of which 54 received first‐line chemotherapy, and 39 received chemotherapy plus immune checkpoint inhibitors (ICIs). The objective response rate was 50% (27/54) in the chemotherapy group and 76.9% (30/39) in the chemotherapy plus ICIs group. The chemotherapy plus ICIs group achieved significant median PFS benefit (8.8 vs. 34.9 months, p <.001) and median OS benefit (41.8 months vs. not reached, p =.025). Multivariate analysis showed that ICIs and local therapy were independent prognostic factors for PFS. In addition, 17 patients developed immune‐related AEs (IRAEs), of which 15 (38.5%) had Grade 1 or 2 IRAEs and 2 (5.1%) had Grade 3 IRAEs in the chemotherapy plus ICIs group. In conclusion, the efficacy of chemotherapy plus ICIs is superior to chemotherapy, and the adverse effects are manageable in patients with unresectable TC. [ABSTRACT FROM AUTHOR]

Measurement of overall survival (OS) remains the gold standard for interpreting the impact of new therapies for multiple myeloma in phase 3 trials. However, as outcomes have improved, it is increasingly challenging to use OS as the primary endpoint if timely approval of novel agents is to be ensured to enable maximum benefit for patients. Surrogate endpoints of OS, such as progression-free survival (PFS) and response to treatment, have contributed to approval decisions by the Food and Drug Administration (FDA) and European Medicines Agency as endpoints demonstrating clinical benefit, and the FDA has recently supported the use of minimal residual disease (MRD) as an accelerated approval endpoint in multiple myeloma. This review aims to address situations in which the use of PFS as a surrogate endpoint warrants careful interpretation especially for specific subgroups of patients and considers ways to ensure that studies can be designed to account for possible discordance between PFS and OS. The utility of subgroup analyses, including the potential for those not pre-specified, to identify target populations for new agents is also discussed. [ABSTRACT FROM AUTHOR]

AbstractBackgroundAimMaterials and MethodsResultsConclusions and SignificanceLactate dehydrogenase (LDH) is involved in the Warburg effect. Elevated serum LDH is a prognostic marker for metastatic solid cancer.To investigate the prognostic impact of serum LDH in patients with head and neck squamous cell carcinoma treated with immune checkpoint inhibitors (ICIs).This retrospective study included 129 patients treated with ICIs between 2017 and 2023. The effects of pretreatment LDH, LDH at 3 months, and change in LDH during the first 3 months (ΔLDH) on overall survival (OS) and progression-free survival (PFS) were analyzed using the Kaplan–Meier method and Cox regression model.The 1-year PFS and OS rates for high and low groups were 6.0% and 30.1% for pretreatment LDH (p = 0.044), 25.7% and 38.3% for on-treatment LDH (p = 0.079), and 14.3% and 38.7% for ΔLDH (p = 0.008), as well as 42.1% and 60.9% for pretreatment LDH (p = 0.109), 56.0% and 80.5% (p < 0.001) for on-treatment LDH, and 31.0% and 81.0% for ΔLDH (p < 0.001), respectively. ΔLDH was an independent prognostic factor for both PFS and OS.ΔLDH can be used to predict ICI treatment outcomes and as a marker in deciding to continue ICI therapy. [ABSTRACT FROM AUTHOR]

Introduction: The estimated dose of radiation to immune cells (EDRIC) has been shown to correlate with the overall survival (OS) of patients who receive definitive thoracic radiotherapy. However, the planning target volume (PTV) may be a confounding factor. We assessed the prognostic value of EDRIC for non-small cell lung cancer (NSCLC) in patients who underwent postoperative radiotherapy (PORT) with homogeneous PTV. Methods: Patients with NSCLC who underwent PORT between 2004 and 2019 were included. EDRIC was computed as a function of the number of radiation fractions and mean doses to the lungs, heart, and remaining body. The correlations between EDRIC and OS, disease-free survival (DFS), locoregional-free survival (LRFS), and distant metastasis-free survival (DMFS) were analyzed using univariate and multivariate Cox models. Kaplan–Meier analysis was performed to assess the survival difference between low- and high-EDRIC groups. Results: In total, 345 patients were analyzed. The mean EDRIC was 6.26 Gy. Multivariate analysis showed that higher EDRIC was associated with worse outcomes in terms of OS (hazard ratio [HR] 1.207, P =.007), DFS (HR 1.129, P =.015), LRFS (HR 1.211, P =.002), and DMFS (HR 1.131, P =.057). In the low- and high-EDRIC groups, the 3-year OS was 81.2% and 74.0%, DFS 39.8% and 35.0%, LRFS 70.4% and 60.5%, and DMFS 73.9% and 63.1%, respectively. Conclusions: EDRIC is an independent prognostic factor for survival in patients with NSCLC undergoing PORT. Higher doses of radiation to the immune system are associated with tumor progression and poor survival. Organs at risk for the immune system should be considered during radiotherapy planning.

Background: Evidence comparing the efficacy of different treatments for patients with unresectable colorectal liver metastases (CRLM) receiving firstline or maintenance therapy is sparse. We aimed to assess the efficacy and safety of these treatments, with a distinct focus on evaluating first-line and maintenance treatments separately. Methods: We conducted Bayesian network meta-analyses, sourcing Englishlanguage randomized controlled trials (RCTs) published through July 2023 from databases including PubMed, Embase, the Cochrane Library, ClinicalTrials.gov, and key conference proceedings. Phase â...¡ or â...¢ trials that assessed two or more therapeutic regimens were included. Primary outcome was overall survival (OS). Secondary outcomes included progression-free survival (PFS), objective response rate (ORR), adverse events graded as 3 or above (SAE), and R0 liver resection rate. Hazards Ratios (HRs) and 95% confidence intervals (CI) were used as effect size for OS and PFS, Odds Ratios (ORs) and 95% CI were used for ORR, SAEs and R0 resection rate. Subgroup and sensitive analyses were conducted to analysis the model uncertainty (PROSPERO: CRD42023420498). Results: 56 RCTs were included (50 for first-line treatment, six for maintenance therapies), with a total of 21,323 patients. Regarding first-line, for OS, the top three mechanisms were: local treatment + single-drug chemotherapy (SingleCT), Targeted therapy (TAR)+SingleCT, and TAR + multi-drug chemotherapy (MultiCT). Resection or ablation (R/A)+SingleCT, S1, and Cetuximab + intensified fluorouracil-based combination chemotherapy (ICTFU) were identified as the best treatments. For PFS, the top three mechanisms were: Immune therapy + TAR + MultiCT, multi-targeted therapy (MultiTAR), TAR + SingleCT. The top three treatments were: Atezolizumab + Bevacizumab + fluorouracil-based combination chemotherapy (CTFU), TAS-102+bevacizumab, Bevacizumab + ICTFU. Cetuximab + CTFU was the best choice for RAS/RAF wild-type patients. Regarding maintenance treatment, Bevacizumab + SingleCT and Adavosertib were the best options for OS and PFS, respectively. For safety, MultiCT was the safest, followed by local treatment + MultiCT, TAR + MultiCT caused the most SAEs. Bevacizumab plus chemotherapy was found to be the safest among all targeted combination therapies. Conclusion: In first-line, local treatment or targeted therapsy plus chemotherapy are the best mechanisms. R/A + SingleCT or CTFU performed the best for OS, Atezolizumab + Bevacizumab + ICTFU was the best option regarding PFS. For RAS/RAF wild-type patients, Cetuximab + CTFU was the optimal option. Monotherapy may be preferred choice for maintenance treatment. Combination therapy resulted in more SAEs when compared to standard chemotherapy. [ABSTRACT FROM AUTHOR]

Preclinical studies suggest that simultaneous HER2/VEGF blockade may have cooperative effects in gastroesophageal adenocarcinomas. In a single-arm investigator initiated clinical trial for patients with untreated advanced HER2+ gastroesophageal adenocarcinoma, bevacizumab was added to standard of care capecitabine, oxaliplatin, and trastuzumab in 36 patients (NCT01191697). Primary endpoint was objective response rate and secondary endpoints included safety, duration of response, progression free survival, and overall survival. The study met its primary endpoint with an objective response rate of 81% (95% CI 65–92%). Median progression free and overall survival were 14.0 (95% CI, 11.3–36.4) and 23.2 months (95% CI, 16.6–36.4), respectively. The median duration of response was 14.9 months. The regimen was well tolerated without unexpected or severe toxicities. In post-hoc ctDNA analysis, baseline ctDNA features were prognostic: Higher tumor fraction and alternative MAPK drivers portended worse outcomes. ctDNA at resistance identified oncogenic mutations and these were detectable 2–8 cycles prior to radiographic progression. Capecitabine, oxaliplatin, trastuzumab and bevacizumab shows robust clinical activity in HER2+ gastroesophageal adenocarcinoma. Combination of VEGF inhibitors with chemoimmunotherapy and anti-PD1 regimens is warranted. Preclinical studies indicate that simultaneous HER2 and VEGF blockade may be beneficial in gastroesophageal adenocarcinoma (GEA). Here, the authors report the efficacy and biomarker analysis of a phase II clinical trial investigating the combination of bevacizumab (anti-VEGF) and standard-of-care CAPOX (capecitabine, oxaliplatin) and trastuzumab in previously untreated advanced HER2 + GEA.

Background: Intermediate-stage (BCLC-B) hepatocellular carcinoma (HCC) beyond the up-to-11 criteria represent a significant therapeutic challenge due to high and heterogeneous tumor burden. This study evaluated the effectiveness and safety of transarterial chemoembolization (TACE) in combination with lenvatinib and tislelizumab for these patients. Methods: In this retrospective cohort study, patients with unresectable intermediate-stage HCC beyond the up-to-11 criteria were enrolled and divided into TACE monotherapy (T), TACE combined with lenvatinib (TL), or TACE plus lenvatinib and tislelizumab (TLT) group based on the first-line treatment, respectively. The primary endpoint was overall survival (OS). The secondary outcomes included progression-free survival (PFS), tumor response according to RESIST1.1 and modified RECIST, and adverse events (AEs). Results: There were 38, 45, and 66 patients in the T, TL, and TLT groups, respectively. The TLT group exhibited significantly higher ORR and DCR than the other two groups, as assessed by either mRECIST or RECIST 1.1 (all P<0.05). Median PFS and OS were significantly longer in the TLT group compared with the T group (PFS: 8.5 vs. 4.4 months; OS: 31.5 vs. 18.5 months; all P<0.001) and TL group (PFS: 8.5 vs. 5.5 months; OS: 31.5 vs. 20.5 months; all P<0.05). The incidence of TRAEs was slightly higher in the TLT and TL groups than in the T group, while all the toxicities were tolerable. No treatment-related death occurred in all groups. Conclusions: TACE combined with lenvatinib and tislelizumab significantly improved the survival benefit compared with TACE monotherapy and TACE plus lenvatinib in patients with intermediate-stage HCC beyond the up-to-11 criteria, with an acceptable safety profile.

The prognosis of patients with advanced high-grade (G3) digestive neuroendocrine neoplasms (NENs) is rather poor. The addition of immune checkpoint inhibition to platinum-based chemotherapy may improve survival. NICE-NEC (NCT03980925) is a single-arm, phase II trial that recruited chemotherapy-naive, unresectable advanced or metastatic G3 NENs of gastroenteropancreatic (GEP) or unknown origin. Patients received nivolumab 360 mg intravenously (iv) on day 1, carboplatin AUC 5 iv on day 1, and etoposide 100 mg/m2/d iv on days 1–3, every 3 weeks for up to six cycles, followed by nivolumab 480 mg every 4 weeks for up to 24 months, disease progression, death or unacceptable toxicity. The primary endpoint was the 12-month overall survival (OS) rate (H0 50%, H1 72%, β 80%, α 5%). Secondary endpoints were objective response rate (ORR), duration of response (DoR), progression-free survival (PFS), and safety. From 2019 to 2021, 37 patients were enrolled. The most common primary sites were the pancreas (37.8%), stomach (16.2%) and colon (10.8%). Twenty-five patients (67.6%) were poorly differentiated carcinomas (NECs) and/or had a Ki67 index >55%. The ORR was 56.8%. Median PFS was 5.7 months (95%CI: 5.1-9) and median OS 13.9 months (95%CI: 8.3-Not reached), with a 12-month OS rate of 54.1% (95%CI: 40.2-72.8) that did not meet the primary endpoint. However, 37.6% of patients were long-term survivors (>2 years). The safety profile was consistent with previous reports. There was one treatment-related death. Nivolumab plus platinum-based chemotherapy was associated with prolonged survival in over one-third of chemonaïve patients with G3 GEP-NENs, with a manageable safety profile. Immune checkpoint inhibitors have been incorporated as the standard of care for some high-grade neuroendocrine neoplasms (NEN), but their efficacy in digestive NEN is still unclear. Here the authors report the results of a phase II trial of nivolumab (anti-PD1) in combination with platinum-doublet chemotherapy (carboplatin-etoposide) as first-line treatment in patients with unresectable or metastatic advanced grade 3 NENs of gastro-enteropancreatic or unknown origin.

This phase II trial aimed to determine the efficacy and safety of induction chemoimmunotherapy of camrelizumab plus modified TPF in locally advanced hypopharyngeal squamous cell carcinoma (LA HSCC) (NCT04156698). The primary endpoint was objective response rate (ORR), and secondary endpoints were 3-year overall survival (OS), progression-free survival (PFS), larynx preservation rate (LPR), and metastasis-free survival (MFS). Patients (cT3-4aN0-2M0), regardless of sex, received induction chemoimmunotherapy for three cycles: camrelizumab 200 mg d1, docetaxel 75 mg/m2 d1, cisplatin 25 mg/m2 d1-3, and capecitabine 800 mg/m2 bid d1-14, q21d. Patients were assigned to radioimmunotherapy if they had a complete or partial response, those with stable or progressive disease underwent surgery and adjuvant (chemo)radiotherapy. Camrelizumab was maintained post-radioimmunotherapy. Fifty-one patients were enrolled with a median follow-up duration of 23.7 months. After induction therapy, the ORR was 82.4% (42/51), meeting the prespecified endpoint. Grade 3/4 adverse events occurred in 26 patients, and no treatment-related death occurred. As three-year outcomes were immature, two-year OS, PFS and LPR were reported. As no distant metastatic event had occurred, MFS was not reported here. The two-year OS, PFS, and LPR rates were 83.0%, 77.1%, and 70.0%, respectively. The induction chemoimmunotherapy of camrelizumab plus TPF showed a high ORR rate with an acceptable safety profile in LA HSCC. Locally advanced hypopharyngeal squamous cell carcinoma is an aggressive form of head and neck cancer with a poor prognosis. Here, the authors report the safety and efficacy of induction camrelizumab (anti-PD-1) and chemotherapy for the treatment of locally advanced hypopharyngeal squamous cell carcinoma.

Background: Renal cell carcinoma (RCC), one of the most fatal urologic tumors, accounts for approximately 3% of all adult cancers and exhibits a high metastatic index at diagnosis and a high rate of relapse. Radical or partial nephrectomy is a curative option for nonmetastatic RCCs. Targeted therapy has been shown to improve the survival of patients with metastatic RCCs. However, the underlying cellular and molecular events associated with RCC pathogenesis are not well known. Methods: To investigate the clinical role of the transcription factor activator protein (AP)-2α in RCC, methylated CpG island recovery assays and microarray analysis were employed. COBRA and RT‒qPCR assays were performed to assess AP-2α expression in RCC. Results: A negative correlation was noted between AP-2α mRNA expression levels and methylation status. Multivariate analyses showed that AP-2α mRNA was a major risk factor not only for overall and disease-free survival in RCC but also for disease-free survival in clear cell RCC. Conclusions: Our results indicated that AP-2α expression was deregulated in RCC and associated with overall patient survival and disease-free survival. Such findings suggest that AP-2α might play an important role in the pathogenesis of RCC. [ABSTRACT FROM AUTHOR]

Background: To investigate the effectiveness and safety of maintenance regimens based on cetuximab, we conducted a real-world, single-arm, retrospective study at a single center. Methods: In Fujian Medical University Union Hospital, patients with unresectable metastatic colorectal cancer (mCRC) who received cetuximab-based maintenance therapy between December 2020 and December 2021 were included. All patients had RAS and BRAF wild-type. The maintenance regimen consisted of 6-12 cycles of cetuximab plus irinotecan (Phase 1) and cetuximab (Phase 2). Patients could receive reintroduction therapy in case of disease progression during Phase 2. Progression-free survival (PFS), overall survival (OS), and safety data were collected. Results: According to the inclusion and exclusion criteria of the study, a total of 108 subjects who received maintenance therapy were included-51 experienced disease progression during Phase 1, with PFS (1) of 7.3 months. Among the 52 patients who entered Phase 2, 17 were still in this phase at the end of follow-up, with PFS (2) of 10.1 months. In Phase 2, 35 patients experienced disease progression, of whom 24 received reintroduction therapy, with PFS (3) of 6.7 months. The overall PFS (total) during the maintenance period was 11.9 months, and the OS was 39.2 months. Grade III or higher adverse events were 4.6% during Phase 1 and 0% during Phase 2. Conclusion: Innovative cetuximab-based maintenance therapy showed a trend toward improving the prognosis of mCRC patients with RAS and BRAF wild-type, while the toxic side effects of maintenance therapy were manageable.

Background: Human epidermal growth factor receptor 2 (HER2) plays an important role in the progression of multiple solid tumors and induces resistance to epidermal growth factor receptor (EGFR) target treatment. However, the expression status and the clinical significance of HER2 in oral squamous cell carcinoma (OSCC) is still controversial. Pyrotinib (PYR) is a promising novel EGFR/HER2 dual inhibitor, whose efficacy in OSCC has not been determined. Methods: 57 locally advanced de novo OSCC patients were included in this study to investigate the relationship between the HER2 expression levels and the prognosis by the tissue microarray analysis (TMA). In vitro and in vivo experiments were performed to retrieve the efficacy of PYR in OSCC. The main downstream of HER2 was evaluated by western blotting in OSCC cell lines and xenograft tumors to explore the potential mechanism of PYR. Results: This study revealed the primary tumor of OSCC had higher HER2 expression levels. Patients with HER2 overexpression had poor overall survival (P < 0.014) and poor disease free survival (P < 0.042). In vitro, PYR suppressed the proliferation, colony formation and migration of OSCC cells. It also promoted apoptosis of OSCC cells and induced cell cycle arrest. Furthermore, PYR was able to inhibit the occurrence and development of OSCC effectively in vivo. Western blotting revealed that PYR suppressed OSCC by inhibiting the phosphorylation of HER2, AKT and ERK. Conclusions: This study exhibited the anti-OSCC effects of PYR in vitro and in vivo, and demonstrated PYR inhibited OSCC cells by inducing apoptosis via the HER2/ AKT and ERK pathway. The result of this study also indicated locally advanced OSCC patients might benefit from HER2 assay and EGFR/HER2 dual inhibit treatment. [ABSTRACT FROM AUTHOR]

Objectives: High‐grade gliomas (HGGs) are highly malignant, aggressive, and have a high incidence and mortality rate. The aim of this study was to investigate survival outcomes and prognostic factors in patients with HGGs. Methods: In this retrospective study, a total of 159 patients with histologically confirmed HGGs were included. The recruitment period was from January 2011 to December 2019. We evaluated patient demographic data, tumor characteristics, treatment methods, immunocytochemistry results, overall survival (OS) time, and progression‐free survival (PFS) time using Kaplan–<>Meier survival analysis with log‐rank testing. Additionally, we employed Cox regression analysis to identify independent factors associated with survival outcomes. Results: Kaplan–Meier survival analysis revealed that the 1‐, 2‐, and 5‐years OS rates were 81.8%, 50.3%, and 12.6%, respectively. Similarly, the 1‐, 2‐, and 5‐years PFS rates were 50.9%, 22.4%, and 3.1%, respectively. The median OS duration was 35.0 months. The univariate analysis indicated that postoperative pathological classification, grade, and age were significantly associated with patient outcomes (p < 0.01). Among the patients, 147 received concurrent chemoradiotherapy, while 12 did not. The immunohistochemical markers of ki‐67, MGMT, IDH1R132H, and p53 demonstrated statistically significant differences in their prognostic impact (p = 0.001, p = 0.020, p = 0.003, and p = 0.021, respectively). In conclusion, we found that grades, age, pathological classification, ki‐67, MGMT, and IDH1R132H expression were statistically significantly associated with PFS (p < 0.01, p = 0.004, p = 0.003, p = 0.001, p = 0.036, and p = 0.028). Additionally, immunohistochemical expressions of TRIB3 and AURKA were significantly higher in patients with shorter survival (p = 0.015 and p = 0.023). Conclusions: Tumor grade and the use of concurrent chemoradiotherapy after surgery were independent prognostic factors that significantly influenced patient survival. Additionally, tumor grade and MGMT expression were found to be independent factors affecting progression‐free survival (PFS). Notably, the expression of TRIB3 and AURKA was higher in patients with poor survival outcomes. [ABSTRACT FROM AUTHOR]

This 10-year retrospective cohort study at a single-center clinic in Germany aimed to analyze the outcomes of endometrial cancer patients and explore the impact of lymphovascular invasion (LV) on patient outcomes and disease-free survival (DFS). Identifying correlations among demographic data, tumor characteristics, treatment modalities, and survival outcomes could enhance patient management and improve survival rates. The study encompassed patients diagnosed and treated for endometrial cancer from January 2010 to December 2020. Clinical and pathological data were extracted from medical records for 311 patients, focusing on variables such as age, histological type, tumor grade, type of surgical treatment, and adjuvant therapies. Survival analysis was conducted using the Kaplan–Meier method and multivariate Cox proportional hazard models to identify factors independently associated with survival. The study demonstrated that lymphovascular invasion significantly impacted survival outcomes on Kaplan–Meier analysis (log-rank p-value = 0.0058). Patients with LV showed a marked decrease in DFS compared to those without LV invasion, with a median DFS of 3.2 years and a hazard ratio of 2.18 (95% CI: 1.56–3.04, p < 0.001). Furthermore, high-grade tumors and p53 positivity were strongly associated with reduced DFS, with hazard ratios of 1.93 (p = 0.001) and 2.11 (p < 0.001), respectively. Patients with distant metastasis exhibited the most significant decline in survival, with a hazard ratio of 5.56 (95% CI: 2.45–10.18, p < 0.001). Despite comprehensive surgical and adjuvant therapies, these high-risk factors dictated poorer outcomes. The presence of lymphovascular invasion, high-grade tumors, and genetic markers like MSI and p53 are pivotal in predicting the course of endometrial cancer. This study underscores the necessity for aggressive management strategies in patients exhibiting these high-risk features to potentially improve prognosis and survival outcomes. The findings advocate for enhanced therapeutic strategies tailored to the biological behavior of the tumor, thereby aiming to elevate the overall survival rates for women diagnosed with endometrial cancer.

Simple Summary: This study explores the involvement of the immune system in oral and lung squamous cell carcinoma. Given the increasing recognition of the immune system's significance in cancer, the study analyzes key components of both tumor macroenvironment and microenvironment. In detail, the focus is on systemic inflammation markers, such as Neutrophil-to-Lymphocyte Ratio (NLR), Platelet-to-Lymphocyte Ratio (PLR), and Monocyte-to-Lymphocyte Ratio (MLR). Additionally, this study investigates Tumor-Infiltrating Lymphocytes (TILs) and CD8+ cells in the tumor microenvironment. We aimed to better understand the impact of these prognostic factors on overall survival (OS) and disease-free survival (DSF) in order to enhance cancer risk stratification and guide therapeutic decisions. Background: The interplay between cancer cells and the immune system is crucial in cancer progression and treatment. In this regard, the tumor immune microenvironment and macroenvironment, marked by systemic inflammation markers and TILs, could be considered key prognostic factors in tumors, including oral and lung squamous cell carcinoma. Methods: We conducted a retrospective clinical study on patients with Oral Squamous Cell Carcinoma (OSCC) and Lung Squamous Cell Carcinoma (LUSCC), examining stages, comorbidities, treatments, and outcomes. We evaluated the prognostic significance of pre-surgical systemic inflammation markers and tumor microenvironment composition. Results: Associations were found between systemic inflammation markers—NLR, MLR, and PLR—and tumor microenvironment factors, such as TILs and CD8+ cell prevalence—elevated inflammation markers correlated with advanced stages. Specifically, NLR was prognostic in OSCC, whereas PLR was prognostic in LUSCC. Using a cutoff value, we divided our tumor samples into two prognostic groups. Moreover, TILs levels >15% of tumor stroma correlated with prolonged overall survival in both OSCC and LUSCC, while increased CD8+ expression was linked to extended disease-free survival in LUSCC. Discussion: Systemic inflammation markers and TILs can be valuable prognostic factors of survival, highlighting the immune response's role in OSCC and LUSCC. Despite limited clinical integration of the presented cohorts due to a lack of standardization, we concluded that analyzing tumor immune profiles may offer novel prognostic insights. Conclusions: Future integration into cancer classification could improve risk stratification and treatment guidance. [ABSTRACT FROM AUTHOR]

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

Simple Summary: Response to treatment and prognosis after 223Ra treatment varies among patients. Using a combination of clinical, biochemical, and radiomic data from bone scintigraphy and 18F-Fluorocholine PET/CT obtained from our prospective ChoPET-Rad study, we identified predictive and prognostic variables. The goal was to create a nomogram able to predict therapeutic failure and overall survival, aiding in the selection of more suitable candidates for this treatment. Purpose: We aimed to develop a nomogram able to predict treatment failure, skeletal events, and overall survival (OS) in patients with castration-resistant prostate cancer with bone metastases (CRPC-BM) treated with Radium-223 dichloride (223Ra). Patients and Methods: Patients from the Castilla-La Mancha Spanish region were prospectively included in the ChoPET-Rad multicenter study from January 2015 to December 2022. Patients underwent baseline, interim, and end-of-treatment bone scintigraphy (BS) and 18F-Fluorocholine PET/CT (FCH PET/CT) scans, obtaining multiple imaging radiomics as well as clinical and biochemical variables during follow-up and studying their association with the previously defined end-points. Survival analysis was performed using the Kaplan–Meier method and Cox regression. Multivariate logistic and Cox regression models were calculated, and these models were depicted by means of nomograms. Results: Median progression-free survival (PFS) and OS were 4 and 14 months (mo), respectively. The variables that showed independent and significant association with therapeutic failure were baseline alkaline phosphatase (AP) levels (p = 0.022) and the characteristics of BM on the CT portion of PET/CT (p = 0.017). In the case of OS, the significant variables were therapeutic failure (p = 0.038), the number of lines received after 223Ra (p < 0.001), average SUVmax (p = 0.002), bone marrow infiltration in FCH PET/CT (p = 0.006), and interim FCH PET/CT response (p = 0.048). Final nomograms included these variables, showing good discrimination among the 100 patients included in our study. In the study of skeletal events, only OS showed a significant association in the multivariate analysis, resulting in an inconsistent nomogram design. Conclusions: FCH PET/CT appears to be a good tool for evaluating patients eligible for treatment with 223Ra, as well as for their follow-up. Thus, findings derived from it, such as the morphological characteristics of BM in the CT, bone marrow infiltration, or the response to 223Ra in the interim study, have proven to be solid and useful variables in the creation of nomograms for predicting therapeutic failure and OS.

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

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

Simple Summary: Omission of completion axillary lymph node dissection (cALND) in patients undergoing mastectomy with sentinel node (SN) isolated tumor cells (ITC) or micrometastases is discussed. We evaluated the impact of cALND omission on survival in breast cancer (BC) patients treated by mastectomy with SN ITC or micrometastases. Among 554 BC, the non-SN involvement rate was 13.2%. With a median follow-up of 66.46 months, multivariate analysis showed that cALND omission was significantly associated with overall survival (OS, HR: 2.583, p = 0.043), disease-free survival (DFS, HR: 2.538, p = 0.008), and metastasis-free survival (MFS, HR: 2.756, p = 0.014). For Her2-positive or triple-negative patients, DFS was significantly impacted by cALND omission (HR: 38.451, p = 0.030). In ER-positive Her2-negative patients, DFS, OS, RFS, and MFS were also significantly affected (HR: 2.358, 3.317, 2.538, 2.756). For 161 patients ≤ 50 years with ER-positive/Her2-negative BC, OS and BCSS were notably associated with cALND omission (HR: 103.47 and 50.874). These findings suggest a negative prognostic impact of cALND omission in patients with SN micrometastases or ITC. Omission of completion axillary lymph node dissection (cALND) in patients undergoing mastectomy with sentinel node (SN) isolated tumor cells (ITC) or micrometastases is debated due to potential under-treatment, with non-sentinel node (NSN) involvement detected in 7% to 18% of patients. This study evaluated the survival impact of cALND omission in a cohort of breast cancer (BC) patients treated by mastectomy with SN ITC or micrometastases. Among 554 early BC patients (391 pN1mi, 163 ITC), the NSN involvement rate was 13.2% (49/371). With a median follow-up of 66.46 months, multivariate analysis revealed significant associations between cALND omission and overall survival (OS, HR: 2.583, p = 0.043), disease-free survival (DFS, HR: 2.538, p = 0.008), and metastasis-free survival (MFS, HR: 2.756, p = 0.014). For Her2-positive or triple-negative patients, DFS was significantly affected by cALND omission (HR: 38.451, p = 0.030). In ER-positive Her2-negative BC, DFS, OS, recurrence-free survival (RFS), and MFS were significantly associated with cALND omission (DFS HR: 2.358, p = 0.043; OS HR: 3.317; RFS HR: 2.538; MFS HR: 2.756). For 161 patients aged ≤50 years with ER-positive/Her2-negative cancer, OS and breast cancer-specific survival (BCSS) were notably impacted by cALND omission (OS HR: 103.47, p = 0.004; BCSS HR: 50.874, p = 0.035). These findings suggest a potential negative prognostic impact of cALND omission in patients with SN micrometastases or ITC. Further randomized trials are needed. [ABSTRACT FROM AUTHOR]

Simple Summary: The incidence of metastatic melanoma is rising, making it imperative to identify patients who do not benefit from immunotherapy. This study aimed to develop a radiomic biomarker, using segmentations from 146 baseline and 146 first follow-up CT scans, to predict best overall response, progression-free survival, and overall survival across various immunotherapies. We volumetrically segmented the total tumour load, excluding cerebral metastases. This study also examined whether reducing the number of segmented metastases per patient affects predictive accuracy. The findings suggest that delta radiomics could enhance the prediction of best overall response, progression-free survival, and overall survival in metastatic melanoma patients undergoing first-line immunotherapy. Although volumetric whole tumour load segmentation is complex, it may provide predictive benefits. Background: The prevalence of metastatic melanoma is increasing, necessitating the identification of patients who do not benefit from immunotherapy. This study aimed to develop a radiomic biomarker based on the segmentation of all metastases at baseline and the first follow-up CT for the endpoints best overall response (BOR), progression-free survival (PFS), and overall survival (OS), encompassing various immunotherapies. Additionally, this study investigated whether reducing the number of segmented metastases per patient affects predictive capacity. Methods: The total tumour load, excluding cerebral metastases, from 146 baseline and 146 first follow-up CTs of melanoma patients treated with first-line immunotherapy was volumetrically segmented. Twenty-one random forest models were trained and compared for the endpoints BOR; PFS at 6, 9, and 12 months; and OS at 6, 9, and 12 months, using as input either only clinical parameters, whole-tumour-load delta radiomics plus clinical parameters, or delta radiomics from the largest ten metastases plus clinical parameters. Results: The whole-tumour-load delta radiomics model performed best for BOR (AUC 0.81); PFS at 6, 9, and 12 months (AUC 0.82, 0.80, and 0.77); and OS at 6 months (AUC 0.74). The model using delta radiomics from the largest ten metastases performed best for OS at 9 and 12 months (AUC 0.71 and 0.75). Although the radiomic models were numerically superior to the clinical model, statistical significance was not reached. Conclusions: The findings indicate that delta radiomics may offer additional value for predicting BOR, PFS, and OS in metastatic melanoma patients undergoing first-line immunotherapy. Despite its complexity, volumetric whole-tumour-load segmentation could be advantageous. [ABSTRACT FROM AUTHOR]

Simple Summary: We retrospectively evaluated the clinical outcomes and prognostic factors of 127 patients with nonmetastatic castration-resistant prostate cancer (nmCRPC) treated with first-line androgen receptor signaling inhibitors (ARSI) in real-world clinical practice. Overall survival (OS), metastatic-free survival (MFS), and prostate-specific antigen–progression-free survival (PSA–PFS) from the initiation of ARSI were assessed. The median OS and MFS for all patients were 79.0 and 42.0 months, respectively. Median PSA–PFS varied among patients treated with enzalutamide, abiraterone acetate, apalutamide, and darolutamide (27.0, 20.0, 10.0, and 14.0 months, respectively; p = 0.33). Multivariate analysis indicated that a baseline PSA level of ≥3.67 ng/mL (p = 0.002) was significantly associated with poorer OS prognosis. ARSI demonstrated favorable efficacy in nmCRPC patients, with no significant differences in clinical outcomes among different types of ARSI. High baseline PSA of ARSI was found to have a significantly poor prognosis associated with OS. We conducted a retrospective evaluation of the clinical outcomes and prognostic factors in patients with nonmetastatic castration-resistant prostate cancer (nmCRPC) treated with first-line androgen receptor signaling inhibitors (ARSI) in real-world clinical practice in Japan. Between 2012 and 2023, a total of 127 consecutive patients with nmCRPC received ARSI treatment. Overall survival (OS), metastatic-free survival (MFS), and prostate-specific antigen–progression-free survival (PSA–PFS) from ARSI initiation were assessed using the Kaplan–Meier methodology. Clinical factors associated with OS in nmCRPC were analyzed using the Cox proportional hazards model. Among the patients, 72, 26, 12, and 17 received enzalutamide (ENZ), abiraterone (ABI), apalutamide (APA), and darolutamide (DARO) as first-line therapy. The median OS and MFS for all patients were 79.0 and 42.0 months, respectively. Median PSA–PFS was 27.0, 20.0, 10.0, and 14.0 months for patients treated with ENZ, ABI, APA, and DARO, respectively (p = 0.33). Multivariate analysis revealed that a baseline PSA level ≥ 3.67 ng/mL at ARSI initiation was significantly associated with poorer OS (p = 0.002). ARSI demonstrated favorable efficacy in nmCRPC patients. There were no significant differences in clinical outcomes among different types of ARSI therapy for nmCRP. Elevated baseline PSA at ARSI initiation was significantly associated with poorer OS. [ABSTRACT FROM AUTHOR]

Simple Summary: The adrenal glands represent a frequent localization area for metastases of various primary tumors. The standard of care for treating adrenal metastases is currently surgical resection, but radiotherapy is becoming a feasible and well-tolerated treatment alternative. However, the literature shows contradictory results regarding the optimal local treatment for adrenal metastases. This study analyzed oncological outcomes (local control, progression free survival, and overall survival) and complication rates after stereotactic body radiotherapy or surgical resection of adrenal metastases to further asses the benefits of stereotactic body radiotherapy. To our knowledge, this analysis is the first direct comparison of stereotactic body radiotherapy and adrenalectomy for adrenal metastases. Background: This single-center retrospective study aimed to evaluate the efficacy and toxicity profiles of stereotactic body radiotherapy (SBRT) and surgical resection in patients with adrenal metastases originating from solid tumors. Methods/Materials: Patients with advanced tumor conditions or comorbidities typically received SBRT, whereas those considered physically fit underwent standard surgical treatment. Endpoints included local control (LC), progression free survival (PFS), overall survival (OS), and complication rates (CR). Results: 41 patients with 48 adrenal metastases were included, with 27 (65.9%) patients receiving SBRT and 14 (34.1%) patients undergoing adrenalectomy. One- and two-year LC values were 100% for both periods after adrenalectomy, and 70.0% and 52.5% after SBRT (p = 0.001). PFS showed values of 40.2% and 32.1% at one and two years after adrenalectomy and of 10.6% for both periods after SBRT (p = 0.223). OS was 83.3% both one and two years after surgery and 67.0% and 40.2% after SBRT (p = 0.031). There was no statistically significant difference between the two groups regarding acute complications (p = 0.123). Conclusion: Despite potential confounders, adrenalectomy exhibited statistically significant superior LC and OS compared to SBRT in managing adrenal metastases, while both treatment methods displayed acceptable toxicity profiles. However, patient selection bias must be taken into account when directly comparing the two therapy modalities. Nevertheless, the study provides new and important results for the scientific and medical communities regarding oncological outcomes after SBRT or surgical resection of adrenal metastases.

Simple Summary: Poly(adenosine diphosphate–ribose) polymerase inhibitors (PARP-is) play crucial roles in the treatment of ovarian cancer. However, the best therapeutic strategy for recurrence during PARP-i maintenance therapy remains unknown. The aim of this study was to elucidate the efficacy of platinum-based chemotherapy after PARP-i treatment in recurrent ovarian cancer. Eighteen patients were enrolled in the present study. The median progression-free survival (PFS) for all patients was 6.5 months, and the median overall survival (OS) was 17.6 months. The evaluation of the risk factors for PFS revealed that bevacizumab use in subsequent therapies was significantly associated with extended PFS. The median PFS was significantly longer in the chemotherapy with the bevacizumab group than in chemotherapy alone (8.9 months vs. 3.1 months, log-rank p = 0.022). The present study highlighted that platinum-based chemotherapy with bevacizumab in subsequent therapies would provide substantial benefits in the PFS of patients with recurrent ovarian cancer. The clinical outcomes in patients with ovarian cancer have been significantly improved by Poly(adenosine diphosphate–ribose) polymerase inhibitors (PARP-is). However, the best therapeutic strategy for recurrence during PARP-i maintenance therapy remains unknown. Herein, we elucidated the efficacy of platinum-based chemotherapy after PARP-i treatment in recurrent ovarian cancer. Eligible patients had experienced relapses during PARP-i maintenance therapy lasting at least 6 months and had received subsequent platinum-based chemotherapy at our institution between January 2019 and March 2024. Progression-free survival (PFS), overall survival (OS), and risk factors for PFS were evaluated. Sixty-six patients were assessed for eligibility and eighteen were enrolled. The median follow-up period was 14.5 months. The PFS and OS of all patients were 6.5 and 17.6 months, respectively. The evaluation of the risk factors for PFS revealed that age, pathological type, duration of PARP-i maintenance therapy, prior lines of chemotherapy, and PARP-i dose reduction were not significant prognostic markers. However, bevacizumab use in subsequent therapies significantly extended the PFS. The median PFS was 3.1 months in the chemotherapy-alone group and 8.9 months in the chemotherapy with bevacizumab group (log-rank p = 0.022). Platinum-based chemotherapy with bevacizumab in subsequent therapies would provide substantial benefits in the PFS of patients with recurrent ovarian cancer. [ABSTRACT FROM AUTHOR]

Simple Summary: The development of HER2-inhibitors for the treatment of HER2-positive breast cancer represented a breakthrough in targeted tumor therapy. However, as for other targeted therapeutics, drug resistance remains a serious challenge to the treatment of HER2+ BC. Recent research has identified critical biomarkers for HER2-inhibitor resistance and explored more effective treatment regimens in HER2+ breast cancer to overcome drug resistance; however, research on several potential biomarkers and promising alternative therapies remains incomplete. HER2 (human epidermal growth factor receptor 2) is highly expressed in a variety of cancers, including breast, lung, gastric, and pancreatic cancers. Its amplification is linked to poor clinical outcomes. At the genetic level, HER2 is encoded by the ERBB2 gene (v-erb-b2 avian erythroblastic leukemia viral oncogene homolog 2), which is frequently mutated or amplified in cancers, thus spurring extensive research into HER2 modulation and inhibition as viable anti-cancer strategies. An impressive body of FDA-approved drugs, including anti-HER2 monoclonal antibodies (mAbs), antibody–drug conjugates (ADCs), and HER2-tyrosine kinase inhibitors (TKIs), have demonstrated success in enhancing overall survival (OS) and disease progression-free survival (PFS). Yet, drug resistance remains a persistent challenge and raises the risks of metastatic potential and tumor relapse. Research into alternative therapeutic options for HER2+ breast cancer therefore proves critical for adapting to this ever-evolving landscape. This review highlights current HER2-targeted therapies, discusses predictive biomarkers for drug resistance, and introduces promising emergent therapies—especially combination therapies—that are aimed at overcoming drug resistance in the context of HER2+ breast cancer.

Introduction: Atezolizumab plus bevacizumab (Atez/Bev) is the preferred treatment for advanced hepatocellular carcinoma (HCC). However, biomarkers of therapeutic efficacy have remained unclear. We took a retrospective approach to explore the role of prognostic nutritional index (PNI) for predicting the outcomes of Atez/Bev treatment. Methods: One hundred 25 HCC patients were enlisted; these patients received Atez/Bev treatment and underwent dynamic computerized tomography/magnetic resonance imaging to determine the treatment response on at least one occasion between October 2020 and January 2023, and their PNI before treatment and at the beginning of the second cycle (PNI-2c) was evaluated. Results: During the initial evaluation, 2 (2%), 28 (22%), 70 (56%), and 25 (20%) patients exhibited a complete response, partial response, stable disease, and progressive disease (PD), respectively. Patients with non-PD tended to have higher PNI at baseline and PNI-2c than those with PD (p = 0.245 and 0.122, respectively), with optimal baseline PNI and PNI-2c cut-off values of 42.6 and 40.4, respectively. PNI at baseline could not be used to predict overall survival (OS) or progression-free survival (PFS). However, PNI-2c predicted OS and PFS (PNI-2c ≥ 40.4 vs. < 40.4: 25.3 vs. 16.2 months, p = 0.008 for OS; 12.7 vs. 8.4 months, p = 0.036 for PFS). A multivariate analysis showed a significant association between PNI-2c and OS. Conclusions: PNI-2c is a predictor of prognosis in HCC patients treated with Atez/Bev therapy.

Introduction: The treatment of hepatocellular carcinoma (HCC) with transarterial chemoembolization (TACE) and lenvatinib individually has shown favorable outcomes, but there is currently no meta-analysis based on randomized controlled trials (RCTs) to investigate the efficacy and safety of this combined treatment for HCC. The aim of this study was to identify the efficacy and safety of TACE plus lenvatinib for the treatment of HCC. Methods: A systematic search of MEDLINE (via PubMed), the Cochrane Library, EMBASE, and the Web of Science was conducted on July 31, 2023. RCTs evaluating the efficacy and safety of TACE in combination with lenvatinib for the treatment of HCC were included. The risk of bias in the included studies was assessed using the Risk of Bias 2 tool. Outcome measures such as objective response rate (ORR), complete remission (CR), progression-free survival (PFS), overall survival (OS), and safety parameters were extracted from the included studies. Binary outcomes were analyzed using odds ratio (OR), risk ratio, or hazard ratio (HR), while continuous variables were analyzed using mean difference (MD) or standardized MD in RStudio. The quality of the evidence was graded using the GRADE approach. Heterogeneity was considered significant when the I-squared was 50% or less. Results: Five RCTs involving 638 patients were included. The meta-analysis revealed that patients in the TACE plus lenvatinib group had a significantly higher mean ORR compared to the control group (OR: 3.65, 95% confidence interval [CI]: 2.50–5.32, fixed-effects model; OR: 3.58, 95% CI: 2.45–5.24, random-effects model, I2 = 0, moderate quality). Specifically, 40.9% of patients in the TACE plus lenvatinib group achieved a PR, which was significantly higher than the control group (OR: 3.51, 95% CI: 2.41–5.13, fixed-effects model; OR: 3.46, 95% CI: 2.36–5.07, random-effects model, I2 = 0, moderate quality). The HR for OS was 0.47 (95% CI: 0.35–0.62, fixed-effects model and random-effects model, I2 = 0, moderate quality). The meta-analysis revealed that the TACE plus lenvatinib group had a significantly higher total adverse effects rate than the control group (OR: 1.86, 95% CI: 1.01–3.43, fixed-effects model; OR: 1.85, 95% CI: 1.00–3.43, random-effects model, I2 = 0, moderate quality). Conclusion: Our study suggests that the combination of TACE and lenvatinib in the treatment of HCC has shown promising results, with extended OS and improved ORR. [ABSTRACT FROM AUTHOR]

Aim: To see whether prophylactic central compartment dissection is recommended for advanced papillary thyroid cancer or as part of selective neck node dissection. Central compartment dissection is a technically demanding surgical procedure and carries a higher incidence of complications. The present retrospective case-control study analysed the impact of prophylactic central compartment dissection on the long-term outcome of advanced (N0-T3/T4) papillary thyroid cancer. Materials and methods: Case records of patients operated on for papillary thyroid cancer from 2005 to 2010 were reviewed and patients with Tumour stage 3–4 and N0 nodal status were included in the study. The institutional protocol was to perform total thyroidectomy with central compartment dissection during the early phase of the study period (2005 to 2008) but this strategy was shifted to total thyroidectomy alone during the latter phase. Fifty-five patients were included in the study and 29 of the cohort had total thyroidectomy with prophylactic central compartment dissection as the primary surgery and the remaining 26 had a total thyroidectomy as the primary surgical procedure. Result: Patients were followed up for a median duration of 115 months and found to have no significant difference in the incidences of loco-regional recurrences between the groups. (n:4 (14%) Vs n: 3 (12%) p =.463). The disease-free survival and overall survival were not significantly different in the groups. There was a trend to an increase in the incidence of permanent hypoparathyroidism in patients who had central compartment dissection. Conclusion: Prophylactic central compartment dissection did not influence the 10-year outcome of advanced node-negative papillary thyroid cancers. [ABSTRACT FROM AUTHOR]

BACKGROUND Triplet or quadruplet therapies incorporating proteasome inhibitors, immunomodulators, and anti-CD38 antibodies have led to prolonged survival among patients with newly diagnosed multiple myeloma; however, most patients have a relapse. Frontline lenalidomide therapy has increased the number of patients with lenalidomide-refractory disease at the time of the first relapse. METHODS In this phase 3, randomized, open-label trial, we evaluated belantamab mafodotin, pomalidomide, and dexamethasone (BPd), as compared with pomalidomide, bortezomib, and dexamethasone (PVd), in lenalidomide-exposed patients who had relapsed or refractory myeloma after at least one line of therapy. The primary end point was progression-free survival. Disease response and safety were also assessed. RESULTS A total of 302 patients underwent randomization; 155 were assigned to the BPd group, and 147 to the PVd group. At a median follow-up of 21.8 months (range, <0.1 to 39.2), the 12-month estimated progression-free survival with BPd was 71% (95% confidence interval [CI], 63 to 78), as compared with 51% (95% CI, 42 to 60) with PVd (hazard ratio for disease progression or death, 0.52; 95% CI, 0.37 to 0.73; P<0.001). Data on overall survival were immature. The percentage of patients with a response to treatment (partial response or better) was 77% (95% CI, 70 to 84) in the BPd group and 72% (95% CI, 64 to 79) in the PVd group; 40% (95% CI, 32 to 48) and 16% (95% CI, 11 to 23), respectively, had a complete response or better. Grade 3 or higher adverse events occurred in 94% of the patients in the BPd group and 76% of those in the PVd group. Ocular events occurred in 89% of the patients who received BPd (grade 3 or 4 in 43%) and 30% of those who received PVd (grade 3 or 4 in 2%); ocular events in the BPd group were managed with belantamab mafodotin dose modification. Ocular events led to treatment discontinuation in 9% of the patients in the BPd group and in no patients in the PVd group. CONCLUSIONS Among lenalidomide-exposed patients with relapsed or refractory myeloma, BPd conferred a significantly greater benefit than PVd with respect to progression-free survival, as well as deeper, more durable responses. Ocular events were common but were controllable by belantamab mafodotin dose modification. [ABSTRACT FROM AUTHOR]

BACKGROUND Belantamab mafodotin had single-agent activity in patients with relapsed or refractory multiple myeloma, a finding that supports further evaluation of the agent in combination with standard-care therapies. METHODS In this phase 3, open-label, randomized trial, we evaluated belantamab mafodotin, bortezomib, and dexamethasone (BVd), as compared with daratumumab, bortezomib, and dexamethasone (DVd), in patients who had progression of multiple myeloma after at least one line of therapy. The primary end point was progression-free survival. Key secondary end points were overall survival, response duration, and minimal residual disease (MRD)-negative status. RESULTS In total, 494 patients were randomly assigned to receive BVd (243 patients) or DVd (251 patients). At a median follow-up of 28.2 months (range, 0.1 to 40.0), median progression-free survival was 36.6 months (95% confidence interval [CI], 28.4 to not reached) in the BVd group and 13.4 months (95% CI, 11.1 to 17.5) in the DVd group (hazard ratio for disease progression or death, 0.41; 95% CI, 0.31 to 0.53; P<0.001). Overall survival at 18 months was 84% in the BVd group and 73% in the DVd group. An analysis of the restricted mean response duration favored BVd over DVd (P<0.001). A complete response or better plus MRD-negative status occurred in 25% of the patients in the BVd group and 10% of those in the DVd group. Grade 3 or higher adverse events occurred in 95% of the patients in the BVd group and 78% of those in the DVd group. Ocular events were more common in the BVd group than in the DVd group (79% vs. 29%); such events were managed with dose modifications, and events of worsening visual acuity mostly resolved. CONCLUSIONS As compared with DVd therapy, BVd therapy conferred a significant benefit with respect to progression-free survival among patients who had relapsed or refractory multiple myeloma after at least one line of therapy. Most patients had grade 3 or higher adverse events. [ABSTRACT FROM AUTHOR]

The aim of this study was to describe the long-term outcome of asymptomatic BRCA1/2 germline pathogenic variant (GPV) carriers with high-grade serous carcinoma (HGSC) in their risk-reducing salpingo-oophorectomy (RRSO) specimen. In a previously described cohort of asymptomatic BRCA1/2 GPV carriers derived from the Hereditary Breast and Ovarian cancer in the Netherlands (HEBON) study, women with HGSC at RRSO were identified. Main outcome was ten-year disease-free survival (DFS). Secondary outcomes were time to recurrence, ten-year disease-specific survival (DSS), ten-year overall survival (OS). Patient, disease and treatment characteristics associated with recurrence were described. The 28 included women with HGSC at RRSO were diagnosed at a median age of 55.3 years (range: 33.5–74.3). After staging, eighteen women had (FIGO) stage I, three stage II and five had stage III disease. Two women did not undergo surgical staging and were classified as unknown stage. After a median follow-up of 13.5 years (range: 9.1–24.7), six women with stage I (33%), one woman with stage II (33%), two women with stage III (40%) and none of the women with unknown stage developed a recurrence. Median time to recurrence was 6.9 years (range: 0.8–9.2 years). Ten-year DFS was 68%, ten-year DSS was 88% and ten-year OS was 82%. Most asymptomatic BRCA1/2 GPV carriers with HGSC at RRSO were diagnosed at an early stage. Nevertheless, after a median follow-up of 13.5 years, nine of the 28 women with HGSC at RRSO developed a recurrence after a median of 6.9 years. • Three-quarters of the asymptomatic BRCA1/2 GPV carriers with HGSC at RRSO had early stage disease. • The ten-year disease-free survival was 68%, ten-year disease-specific survival was 88% and ten-year overall-survival was 82%. • After a median follow-up of 13.5 years, recurrence rate was 32% with median time to recurrence of 6.9 years (range 0.8–9.2). • Timely RRSO remains the only reliable method of reducing mortality of HGSC in BRCA1/2 GPV carriers.

To investigate the role of BRCA1/2 mutations in early ovarian cancer (eOC) (International Federation of Gynecology and Obstetrics FIGO 2014 stage I-II), and its impact on prognosis after relapse. In this multicenter retrospective study, clinical and survival data from high-grade serous (HGS)-eOC patients at presentation and recurrence were compared according to BRCA status: BRCA-mutated (BRCAmut) vs. BRCA wild-type (BRCAwt). Among 191 HGS-eOC patients, 89 were BRCAmut and 102 BRCAwt. There was no significant difference according to the BRCA status in terms of Progression-Free Survival (PFS). A longer Overall Survival (OS) was found in BRCAmut patients. Stage I patients had significantly improved PFS vs stage II, regardless of BRCA status. At multivariate analysis, stage at diagnosis was the only variable with a significant effect on PFS. No factors were significantly relevant on OS, albeit younger age and BRCA mutation showed a slight impact. Post-Recurrence Survival (PRS) in the BRCAmut population was significantly improved compared with BRCAwt. At multivariate analysis, Secondary Cytoreductive Surgery was the strongest predictor for longer PRS, followed by PARPi maintenance at recurrence. BRCA-status is not a prognostic factor in early ovarian cancer regarding PFS. However, our data suggest a better prognosis after relapse in BRCAm population. • Recurrence rate was similar in BRCAwt and BRCAmut groups (35.3% vs 29.2%). • The recurrence patterns were similar between BRCAmut and BRCAwt • BRCA status has no impact on Progression Free Survival. • Post-recurrence Survival was significantly longer in the BRCAmut group. • A longer Overall Survival was found in BRCAmut compared with BRCAwt patients.

Purpose: To investigate imaging findings on gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid-enhanced magnetic resonance imaging (Gd-EOB-DTPA-enhanced MRI) and prognosis of clear cell hepatocellular carcinoma (CCHCC) comparing with non-otherwise specified hepatocellular carcinoma (NOS-HCC). Methods: The clinical, pathological and MR imaging features of 42 patients with CCHCC and 84 age-matched patients with NOS-HCC were retrospectively analyzed from January 2015 to October 2021. Univariate and multivariate logistic regression and Cox regression analyses were performed to identify independent diagnostic and prognostic factors for CCHCC. Disease-free survival (DFS) and overall survival (OS) were determined by Kaplan–Meier analysis. Results: CCHCC showed fat content more frequently (P < 0.001) and relatively higher Edmondson tumor grade (P = 0.001) compared with NOS-HCC. The lesion-to-muscle ratio (LMR) and lesion-to-liver ratio (LLR) of CCHCC on pre-enhancement T1-weighted imaging (pre-T1WI) (P = 0.001, P = 0.003) and hepatobiliary phase (HBP) (P = 0.007, P = 0.048) were significantly higher than those of NOS-HCC. The area under the curve (AUC) for fat content, LLR on pre-T1WI and their combination with better diagnostic performance in predicting CCHCC were 0.678, 0.666, and 0.750, respectively. There was no statistically significant difference in clinical outcomes between CCHCC and NOS-HCC. Multivariate Cox analysis confirmed that tumor size > 2 cm and enhancing capsule were independent prognostic factors for DFS and OS among CCHCC patients. Conclusion: Fat content and adjusted lesion signal intensity on pre-T1WI and HBP could be used to differentiate CCHCC from NOS-HCC. CCHCC had similar prognosis with NOS-HCC. [ABSTRACT FROM AUTHOR]
