BACKGROUND: In the phase 3 EMPOWER-Cervical 1/GOG-3016/ENGOT-cx9 study, cemiplimab significantly improved overall survival (OS) versus chemotherapy for patients with recurrent or metastatic cervical cancer who progressed after first-line platinum-based chemotherapy. We present a post hoc subgroup analysis of patients enrolled in Japan. METHODS: Patients were enrolled regardless of programmed cell death-ligand 1 status and randomized 1:1 to cemiplimab 350 mg intravenously every 3 weeks or investigators choice  single-agent chemotherapy for up to 96 weeks. Primary endpoint was OS. Key secondary endpoints were progression-free survival (PFS) and objective response rate (ORR). RESULTS: Overall, 608 patients were randomized, of whom 56 (9.2%) were in Japan (cemiplimab, n = 29; chemotherapy, n = 27). The median (range) duration of follow-up was 13.6 (6.0-25.3) versus 18.2 (6.0-38.2) months for patients in Japan and for the overall population, respectively. Median OS (95% confidence interval [CI]) was 8.4 (7.0-not evaluable) and 9.4 (5.4-14.9) months for cemiplimab versus chemotherapy (hazard ratio [HR]: 0.86; 95% CI: 0.43-1.68). Median PFS (95% CI) was 4.0 (1.4-8.2) versus 3.7 (1.8-4.2) months with cemiplimab and chemotherapy (HR: 0.90; 95% CI: 0.50-1.61), respectively. ORR was 17.2% for cemiplimab and 7.4% for chemotherapy (odds ratio, 2.47; 95% CI, 0.44-13.99). Incidence of treatment-emergent adverse events at any grade was 79.3% for cemiplimab and 100% for chemotherapy. Grade ≥3 adverse events were 37.9% versus 66.7% with cemiplimab and chemotherapy, respectively. DISCUSSION: While acknowledging limitations inherent to a small subgroup analysis, the HR of 0.86 observed in Japanese patients suggests an emerging survival benefit despite a 4.6-month shorter median duration of follow-up versus the overall study population.

While high circulating tumor DNA (ctDNA) levels are associated with poor survival for multiple cancers, variant-specific differences in the association of ctDNA levels and survival have not been examined. Here we investigate KRAS ctDNA (ctKRAS) variant-specific associations with overall and progression-free survival (OS/PFS) in first-line metastatic pancreatic ductal adenocarcinoma (mPDAC) for patients receiving chemoimmunotherapy (PRINCE, NCT03214250), and an independent cohort receiving standard of care (SOC) chemotherapy. For PRINCE, higher baseline plasma levels are associated with worse OS for ctKRAS G12D (log-rank p = 0.0010) but not G12V (p = 0.7101), even with adjustment for clinical covariates. Early, on-therapy clearance of G12D (p = 0.0002), but not G12V (p = 0.4058), strongly associates with OS for PRINCE. Similar results are obtained for the SOC cohort, and for PFS in both cohorts. These results suggest ctKRAS G12D but not G12V as a promising prognostic biomarker for mPDAC and that G12D clearance could also serve as an early biomarker of response.

Clinical trials frequently include multiple end points that mature at different times. The initial report, typically based on the primary end point, may be published when key planned co-primary or secondary analyses are not yet available. Clinical Trial Updates provide an opportunity to disseminate additional results from studies, published in JCO or elsewhere, for which the primary end point has already been reported.Sacituzumab govitecan (SG), a first-in-class anti-trophoblast cell surface antigen 2 (Trop-2) antibody-drug conjugate, demonstrated superior efficacy over single-agent chemotherapy (treatment of physicians choice [TPC]) in patients with metastatic triple-negative breast cancer (mTNBC) in the international, multicenter, phase III ASCENT study.Patients were randomly assigned 1:1 to receive SG or TPC until unacceptable toxicity/progression. Final efficacy secondary end point analyses and post hoc analyses of outcomes stratified by Trop-2 expression and human epidermal growth factor receptor 2 status are reported. Updated safety analyses are provided.In this final analysis, SG (n = 267) improved median progression-free survival (PFS; 4.8 v 1.7 months; hazard ratio (HR), 0.41 [95% CI, 0.33 to 0.52]) and median overall survival (OS; 11.8 v 6.9 months; HR, 0.51 [95% CI, 0.42 to 0.63]) over TPC (n = 262). SG improved PFS over TPC in each Trop-2 expression quartile (n = 168); a trend was observed for improved OS across quartiles. Overall, SG had a manageable safety profile, with ≤5% of treatment-related discontinuations because of adverse events and no treatment-related deaths. The safety profile was consistent across all subgroups.These data confirm the clinical benefit of SG over chemotherapy, reinforcing SG as an effective treatment option in patients with mTNBC in the second line or later.

Magnetic resonance image-guided brachytherapy is essential in the management of locally advanced cervical cancer. This study compares disease and toxicity outcomes in cervical cancer patients treated with 24 Gy/3 fractions (Fr) versus the conventional 28 Gy/4 Fr. This retrospective study included 241 consecutive patients with International Federation of Gynecology and Obstetrics 2018 stage IB to IVA cervical cancer treated with definitive chemoradiation between April 2014 and March 2021. Disease-free survival (DFS) was estimated using the Kaplan-Meier method and compared using the log-rank test. Cumulative incidence of local failure (LF), distant failure (DF), and G2+ gastrointestinal (GI), urinary and vaginal toxicity were estimated using the cumulative incidence function with death as a competing risk and compared using Gray's test. Of the 241 patients, 42% received 24 Gy/3 Fr and 58% received 28 Gy/4 Fr. With a median follow-up of 3.2 (range, 0.2-9.2) years, there were 14 local, 41 regional nodal, and 51 distant failures in 63 (26%) patients. No significant differences were found between the 24 Gy/3 Fr and 28 Gy/4 Fr groups in 3-year DFS (77% vs 68%, P =.21), the 3-year cumulative incidence of LF (5% vs 7%, P =.57), DF (22% vs 25%, P =.86), G2+ GI toxicity (11% vs 20%, P =.13), or G2+ vaginal toxicity (14% vs 17%, P =.48), respectively. The 3-year cumulative G2+ urinary toxicity rate was lower in the 24 Gy/3 Fr group (9% vs 23%, P =.03). Patients with cervical cancer treated with 24 Gy/3 Fr had similar DFS, LF, DF, GI, and vaginal toxicity rates and a trend toward a lower G2+ urinary toxicity rate compared with those treated with 28 Gy/4 Fr. A less resource-intensive brachytherapy fractionation schedule of 24 Gy/3 Fr is a safe alternative to 28 Gy/4 Fr for definitive treatment of cervical cancer. [ABSTRACT FROM AUTHOR]

Background: The phase III KEYNOTE-913 study was conducted to evaluate the efficacy and safety of pembrolizumab as first-line therapy in patients with advanced Merkel cell carcinoma (MCC). Objective: The aim was to report results from the primary analysis of KEYNOTE-913. Patients and Methods: Patients with recurrent locally advanced or metastatic MCC received pembrolizumab 200 mg intravenously every 3 weeks for up to 35 treatments (~ 2 years). The primary end point was objective response rate (ORR) per Response Evaluation Criteria in Solid Tumors, version 1.1 (RECIST v1.1) by blinded independent central review (BICR). Secondary end points were duration of response (DOR) and progression-free survival (PFS) per RECIST v1.1 by BICR, overall survival (OS), and safety and tolerability. Results: Fifty-five patients were treated with pembrolizumab. The median time from first dose to data cutoff (February 15, 2024) was 50.3 months (range 38.7–59.4). The ORR was 49% (95% confidence interval [CI] 35–63), with 12 complete responses and 15 partial responses. The median DOR was 39.8 months (range 4.8–52.5+), and the 24-month DOR rate was 69%. The median PFS was 9.3 months (95% CI 3–26), and the 24-month PFS rate was 39%. The median OS was 24.3 months (95% CI 12.4 to not reached), and the 24-month OS rate was 51%. Any-grade treatment-related adverse events (AEs) occurred in 38 patients (69%); 13 patients (24%) experienced grade 3–5 AEs. The most common treatment-related AEs were fatigue (n = 12 [22%]), pruritus (n = 12 [22%]), and lipase increase (n = 10 [18%]). One patient died of treatment-related Guillain-Barré syndrome. Conclusions: Pembrolizumab provided durable antitumor activity and promising survival and had a manageable safety profile in patients with recurrent locally advanced or metastatic MCC, supporting its use in this population. Trial Registration: Clinicaltrials.gov, NCT03783078. [ABSTRACT FROM AUTHOR]

Pembrolizumab plus chemotherapy provides clinically meaningful benefit as first-line therapy for advanced (locoregional extension and residual disease after surgery)/metastatic/recurrent mismatch repair-proficient (pMMR) and mismatch repair-deficient (dMMR) endometrial cancer, with greater magnitude of benefit in the dMMR phenotype. We evaluated the addition of pembrolizumab to adjuvant chemotherapy (with/without radiation therapy) among patients with newly diagnosed, high-risk endometrial cancer without any residual macroscopic disease following curative-intent surgery. We included patients with histologically confirmed high-risk [International Federation of Gynecology and Obstetrics (FIGO) stage I/II of non-endometrioid histology or endometrioid histology with p53/ TP53 abnormality, or stage III/IVA of any histology] endometrial cancer following surgery with curative intent and no evidence of disease postoperatively, with no prior radiotherapy or systemic therapy. Patients were randomised to pembrolizumab 200 mg or placebo every 3 weeks (Q3W) for six cycles added to carboplatin–paclitaxel followed by pembrolizumab 400 mg or placebo every 6 weeks (Q6W) for six cycles per treatment assignment. Radiotherapy was at the investigator's discretion. The primary endpoints were investigator-assessed disease-free survival (DFS) and overall survival in the intention-to-treat population. A total of 1095 patients were randomised (pembrolizumab, n = 545; placebo, n = 550). At this interim analysis (data cut-off, 4 March 2024), 119 (22%) DFS events occurred in the pembrolizumab group and 121 (22%) occurred in the placebo group [hazard ratio 1.02, 95% confidence interval (CI) 0.79-1.32; P = 0.570]. Kaplan–Meier estimates of 2-year DFS rates were 75% and 76% in the pembrolizumab and placebo groups, respectively. The hazard ratio for DFS was 0.31 (95% CI 0.14-0.69) in the dMMR population (n = 281) and 1.20 (95% CI 0.91-1.57) in the pMMR population (n = 814). Grade ≥3 adverse events (AEs) occurred in 386 of 543 (71%) and 348 of 549 (63%) patients in the pembrolizumab and placebo groups, respectively. No treatment-related grade 5 AEs occurred. Adjuvant pembrolizumab plus chemotherapy did not improve DFS in patients with newly diagnosed, high-risk, all-comer endometrial cancer. Preplanned subgroup analyses for stratification factors suggest that pembrolizumab plus chemotherapy improved DFS in patients with dMMR tumours. Safety was manageable.

The prognostic role of circulating tumor DNA (ctDNA)-based molecular residual disease (MRD) detection and its utility for postsurgical risk stratification has been reported in colorectal cancer. In this study, we explored the use of ctDNA-based MRD detection in patients with colorectal liver metastases (CLM), for whom the survival benefit of adjuvant chemotherapy (ACT) after surgical resection remains unclear. Patients with CLM without extrahepatic disease from the GALAXY study (UMIN000039205) were included. The disease-free survival (DFS) benefit of ACT was evaluated in MRD-positive and -negative groups after adjusting for age, gender, number, and size of liver metastases, RAS status, and previous history of oxaliplatin for primary cancer. ctDNA was detected using a personalized, tumor-informed 16-plex polymerase chain reaction-next-generation sequencing (mPCR-NGS) assay. ctDNA-based MRD status was evaluated 2-10 weeks after curative surgery, before the start of ACT. Among 6061 patients registered in GALAXY, 190 surgically resected CLM patients without any preoperative chemotherapy were included with a median follow-up of 24 months (1-48 months). ctDNA positivity in the MRD window was 32.1% (61/190). ACT was administered to 25.1% (48/190) of patients. In the MRD-positive group, 24-month DFS was higher for patients treated with ACT [33.3% versus not reached, adjusted hazard ratio (HR): 0.07, P < 0.0001]; whereas no benefit of ACT was seen in the MRD-negative group (24-month DFS: 72.3% versus 62.2%, adjusted HR: 0.68, P = 0.371). Multivariate analysis showed that the size of liver metastases (HR: 3.94, P = 0.031) was prognostic of DFS in the MRD-positive group. In the MRD-negative group, however, none of the clinicopathological factors were prognostic of DFS. Our data suggest that ACT may offer notable clinical benefits in MRD-positive patients with CLM. MRD status-based risk stratification could be potentially incorporated in future clinical trials for CLM. • Association between ACT benefit and MRD status was assessed in patients with surgically resected colorectal liver metastases. • In the MRD-positive group, the benefit of ACT in improving disease-free survival (DFS) was observed in multivariate analysis. • On the other hand, the benefit of ACT was limited in the MRD-negative group.

Nivolumab plus ipilimumab (NIVO+IPI) has demonstrated superior overall survival (OS) and durable response benefits versus sunitinib (SUN) with long-term follow-up in patients with advanced renal cell carcinoma (aRCC). We report updated analyses with 8 years of median follow-up from CheckMate 214. Patients with aRCC (N = 1096) were randomized to NIVO 3 mg/kg plus IPI 1 mg/kg Q3W × four doses, followed by NIVO (3 mg/kg or 240 mg Q2W or 480 mg Q4W); or SUN (50 mg) once daily for 4 weeks on, 2 weeks off. The endpoints included OS, independent radiology review committee (IRRC)-assessed progression-free survival (PFS), and IRRC-assessed objective response rate (ORR) in intermediate/poor-risk (I/P; primary), intent-to-treat (ITT; secondary), and favorable-risk (FAV; exploratory) patients. With 8 years (99.1 months) of median follow-up, the hazard ratio [HR; 95% confidence interval (CI)] for OS with NIVO+IPI versus SUN was 0.72 (0.62-0.83) in ITT patients, 0.69 (0.59-0.81) in I/P patients, and 0.82 (0.60-1.13) in FAV patients. PFS probabilities at 90 months were 22.8% versus 10.8% (ITT), 25.4% versus 8.5% (I/P), and 12.7% versus 17.0% (FAV), respectively. ORR with NIVO+IPI versus SUN was 39.5% versus 33.0% (ITT), 42.4% versus 27.5% (I/P), and 29.6% versus 51.6% (FAV). Rates of complete response were higher with NIVO+IPI versus SUN in all International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) risk groups (ITT, 12.0% versus 3.5%; I/P, 11.8% versus 2.6%; FAV, 12.8% versus 6.5%). The median duration of response (95% CI) with NIVO+IPI versus SUN was 76.2 versus 25.1 months [59.1 months-not estimable (NE) versus 19.8-33.2 months] in ITT patients, 82.8 versus 19.8 months (54.1 months-NE versus 16.4-26.4 months) in I/P patients, and 61.5 versus 33.2 months (27.8 months-NE versus 24.8-51.4 months) in FAV patients. The incidence of treatment-related adverse events was consistent with previous reports. Exploratory post hoc analyses are reported for FAV patients, those receiving subsequent therapy based on their response status, clinical subpopulations, and adverse events over time. Superior survival, durable response benefits, and a manageable safety profile were maintained with NIVO+IPI versus SUN at 8 years, the longest phase III follow-up for a first-line checkpoint inhibitor combination therapy in aRCC. • We report the longest follow-up (8 years) for a phase III first-line checkpoint inhibitor-based aRCC combination therapy. • Long-term OS remained superior with NIVO+IPI versus SUN in ITT patients (HR 0.72) and in patients with I/P risk (HR 0.69). • ORR benefits were maintained with NIVO+IPI versus SUN in ITT patients (39% and 33%) and I/P risk patients (42% and 27%). • In FAV-risk patients, the OS HR improved over 8 years (0.82) with NIVO+IPI versus SUN, with twice the complete response rate. • Fewer grade 3-4 treatment-related adverse events occurred in patients treated with NIVO+IPI versus SUN (48.4% versus 64.1%).

Background: The real-world efficacy, prognostic factors, and adverse events of second-line nivolumab monotherapy and subsequent third-line therapy for unresectable or metastatic esophageal cancer have not been fully evaluated. Methods: This multi-institutional retrospective cohort study evaluated 184 consecutive patients treated with second-line nivolumab monotherapy for esophageal cancer between March 2021 and December 2022. We assessed tumor response, adverse events, long-term survival, and prognostic factors. Results: Among 128 patients with measurable lesions, the response rate was 23% and the disease control rate for all enrolled patients was 45%. The incidence of grade 3 or higher adverse events was 14%, but no treatment-related deaths presented. Median progression-free survival was 5.1 months and overall survival was 14 months, respectively. C-reactive protein level and performance status were identified as significant prognostic factors of overall survival through Cox proportional hazards analysis. The group with two favorable prognostic factors showed better overall survival than the groups with either one or zero prognostic factors (median overall survival: 22, 15, and 4.4 months, respectively). Among 69 patients who received third-line taxane anticancer agents, the progression-free survival was 6.7 months. Conclusions: Our study demonstrated that the real-world outcomes of second-line nivolumab monotherapy were comparable to those of previous randomized clinical trials in terms of tumor response, safety, and long-term survival. Furthermore, a good performance status and low C-reactive protein levels may identify patients who are likely to benefit from therapy. Third-line chemotherapy after nivolumab treatment may have an enhanced effect; however, further prospective studies are required to confirm this finding. [ABSTRACT FROM AUTHOR]

HERC5, a vital protein in the HERC family, plays crucial roles in immune response, cancer progression, and antiviral defense. This bioinformatic study comprehensively assessed HERC5's significance across various malignancies by analyzing its gene expression, immune and molecular subtype expressions, target proteins, biological functions, and prognostic and diagnostic values in pan‐cancer. We further examined its correlation with clinical features, co‐expressed and differentially expressed genes, and prognosis in clinical subgroups, focusing on endometrial cancer (UCEC). Our findings showed that HERC5 RNA is expressed at low levels in most cancers and significantly differs across immune and molecular subtypes. HERC5 accurately predicts cancer and correlates with most cancer prognoses. In UCEC, HERC5 was significantly associated with age, hormonal status, clinical stage, treatment status, and metastasis. Elevated HERC5 expression was linked to worse progression‐free interval, disease‐specific survival, and overall survival in UCEC, particularly in diverse clinical subgroups. Significant differences in HERC5 expression were also observed in various human cancer cell line validations. In summary, HERC5 may be a critical biomarker for pan‐cancer prognosis, progression, and diagnosis, as well as a promising new target for cancer therapy. [ABSTRACT FROM AUTHOR]

Thymic carcinoma (TC) is a rare form of highly invasive tumors. Currently, the standard first-line therapy involves paclitaxel plus carboplatin treatment, while the recommended regimen for second-line therapy remains uncertain. The purpose of this study is to explore the second-line mode of TC patients. We evaluated the outcome of subjects with advanced TC between 2009 and 2023 in three medical centers, retrospectively. Tumor response was evaluated according to the Response Evaluation Criteria in Solid Tumors, version 1.1 (RECIST v1.1). Kaplan-Meier was used for calculating Progression-free survival (PFS) and overall survival (OS). The factors affecting survival in the real world were evaluated by Cox analysis. Totally 136 patients were included in this study, the median PFS (mPFS) for all subjects was 5.97 months, and the median OS (mOS) was 25.03 months. According to patient's treatment modes, they are divided into monotherapy (n = 95) and combination therapy (n = 41), PFS manifested the difference between two groups (5.17 vs. 9.00 months, P = 0.043). OS also indicated a significant distinction (22.50 vs. 38.00 months, P = 0.017). Furthermore, there was a significant difference in PFS between patients using immunotherapy combined with chemotherapy and those with antivascular therapy (8.57 vs. 13.10 months, P = 0.047). In the second-line therapy for advanced TC, the efficacy of combination therapy was better than monotherapy, especially for immunotherapy combined with antivascular therapy. • One hundred and thirty-six patients were enrolled, including 95 patients with monotherapy and 41 with combination therapy. • The efficacy of combination therapy was better than that of monotherapy. • Immunotherapy combined with anti-angiogenesis therapy showed better efficacy in second-line TC patients.

• Ultra-radical surgery increases postoperative complications and overall mortality rates. • Standard-radical surgery shows comparable survival outcomes with fewer complications. • Preoperative and postoperative CA-125 levels significantly impact survival rates. • FIGO stage and total metastatic lymph nodes are key prognostic factors. • Strategic patient selection and meticulous follow-up improve survival outcomes. To compare overall survival (OS) and morbidity outcomes in patients with advanced epithelial ovarian/tubal/peritoneal cancer undergoing standard-radical (SR) and ultra-radical (UR) surgical procedures based on NICE classification. This retrospective study analyzed data from 282 patients with 2014 FIGO stage III-IV epithelial ovarian cancer operated on between January 2006 and January 2019. The study compared OS, progression-free survival (PFS), and morbidity between SR and UR surgeries. Parameters influencing OS, including preoperative, postoperative, and post-adjuvant chemotherapy CA-125 values, surgical procedures, post-surgical residual tumor, histopathological grade, and FIGO surgical stage, were assessed. Out of 282 patients, 256 met the inclusion criteria. SR surgery was performed in 48 %, and UR surgery in 52 %. The mean preoperative CA-125 value was 1200 ± 1914.83, decreasing to 240.32 ± 373.87 postoperatively. The mean follow-up period was 63.01 ± 47.56 months. UR surgery correlated with significantly higher postoperative complications (p < 0.001), histopathological grade (p = 0.023), FIGO stage (p < 0.001), three-year death rates, and overall mortality rates (p = 0.035). FIGO stage and total metastatic lymph nodes emerged as independent prognostic factors for overall and PFS. In the treatment of epithelial ovarian cancer, evaluating the extent of the tumor before the surgery and showing maximal effort to minimize the residual tumor volume instead of applying UR procedures as the first choice seems to be the most important factor that can affect survival.

Background: Phospholipase A2 (PLA2) is a large family of enzymes involved in the inflammatory process that catalyzes the hydrolysis of membrane phospholipids, leading to the production of free fatty acids and lysophospholipids, starting the arachidonic acid cascade. Their expression has been related to the behavior of several cancers. Our objective is to search for PLA2 expression in prostate cancer (PCa) tissue that correlates with prognosis and survival. Methods: Using qRT-PCR, we analyzed the expression levels of PLA2G1B, PLA2G2A, PLA2G2D, PLA2G4A, PLA2G4B, PLA2G4C, PLA2G4D, PLA2G4E, PLA2G4F, PLA2G6, PLA2G7, PLA2G16, PNPLA1, and PNPLA2 in PCa tissue from 108 patients submitted to radical prostatectomy, followed by a mean time of 163 months. Results: All PLA2 was overexpressed in PCa compared to normal tissue. Interestingly, higher expression of some PLA2 was related to favorable prognostic factors: lower levels of PSA (PLA2G2A, PLA2G4D), lower rates of lymph node metastasis (PLA2G16 and PLA2G1B), and organ-confined disease (PLA2G4A). Most importantly, PLAG4B was independently related to longer disease-free survival. Conclusion: This is the first study exploring comprehensively the expression levels of PLA2 in PCa, showing that the higher expression of some PLA2 should be used as biomarkers of good prognosis and longer disease-free survival.

Background: The C-reactive protein (CRP)-albumin-lymphocyte (CALLY) index is a novel immune nutrition scoring system associated with cancer prognosis. This study investigated the association between the CALLY index and the long-term outcomes of patients with gastric cancer. Methods: We included 175 patients with gastric cancer who underwent curative gastrectomies at the Department of Surgery, International University of Health and Welfare Hospital between January 2011 and October 2019. The CALLY index was calculated based on the levels of serum albumin, serum CRP, and peripheral lymphocyte count. Utilizing both univariate and multivariate analyses, the prognostic value of the CALLY index was investigated. Results: In the multivariate analyses, disease stage (hazard ratio [HR], 7.85; 95% confidence interval [CI], 3.31-18.6; P < .01), microvascular invasion (HR, 2.88; 95% CI, 1.30-6.36; P < .01), and low CALLY index (HR, 2.18; 95% CI, 1.00-4.76; P = .05) were independent and significant predictors of disease-free survival. Low body mass index (HR, 4.15; 95% CI, 1.63-10.6; P < .01), advanced disease stage (HR, 8.22; 95% CI, 3.47-19.5; P < .01), and low CALLY index (HR, 3.00; 95% CI, 1.3-6.93; P = .01) were independent and significant predictors of overall survival. The low CALLY index group had a lower body mass index (P < .01), advanced disease stage (P < .01), and a higher Glasgow prognostic score (P < .01). Conclusions: The CALLY index may be associated with a poor prognosis for gastric cancer, highlighting the utility of a comprehensive assessment using inflammatory, nutritional, and immunological statuses.

Objective: The objective of this study is to analyze the outcomes of patients with resectable/borderline resectable PDAC who receive total neoadjuvant therapy vs upfront surgery. Methods and analysis: Patients who were treated at a single institution from 2006 to 2021 were included. The primary outcome was overall survival (OS). Secondary outcomes included disease free survival (DFS), rates of lymph node positivity, and R0 resection. All survival analyses were performed with intention-to-treat. Results: 26 patients received neoadjuvant chemotherapy and radiation (TNT), 28 received neoadjuvant chemotherapy only (NAC), and 168 received upfront surgery. Demographics were comparable across all three groups. Patients who received TNT or NAC had longer OS and DFS compared to the surgery first patients (P < .01). Patients who received TNT had a lymph node positivity rate of 0% at time of surgery compared to 5.3% and 13.3% in the NAC and surgery-first groups, respectively (P < .01). The rate of R0 resection did not differ between groups (P = .17). Conclusion: Patients with resectable/borderline resectable PDAC who receive neoadjuvant therapy have longer OS and RFS relative to those who receive upfront surgery. [ABSTRACT FROM AUTHOR]

Due to the rarity of lung cancer with cystic imaging manifestations, we explore the clinical features and survival prognosis of such tumors. Imaging characteristics were used to categorize 3,556 patients who underwent surgery for isolated primary lung cancer into one of three groups: those with cystic lung cancer (149), solid lung cancer (1,399), and ground-glass lung cancer (1,160). Propensity score matching by sex and age was performed to analyze the differences in clinical characteristics of lung cancer among the three groups and the correlation between clinical characteristics of cystic lesions and progression-free survival (PFS). The three groups of patients differed in various aspects, including pathological type, smoking history, tumor stage, type of surgery, histological grading, and PFS (P < 0.05). The results of the multifactorial analysis indicated that lung cancer type, pathological type, lymph node metastasis, tumor stage, and histologic grading were independent prognostic factors for lung cancer (P < 0.05). After comparison, there was a difference in prognosis between cystic lung cancer and ground-glass lung cancer (P < 0.05). The clinical features of cystic lung cancer are significantly different from those of ground-glass lung cancer and solid lung cancer. Cystic lesions are independent influencing factors affecting lung cancer, and the prognosis of cystic lung cancer is worse than that of ground-glass lung cancer. • LCCAs have different clinical features from other types of lung cancer. • Prognosis of LCCAs is statistically different from ground-glass lung cancer. • Cystic lesions are an independent influence on non-small cell lung cancer.

Aims: The 2023 FIGO staging criteria for endometrial cancer (EC) introduced marked changes from the 2009 version. The full implication of these changes for patient diagnosis and treatment is unknown. We evaluate the differences in staging and prognostication between the two systems, with and without inclusion of molecular classification. Methods and results: We assigned (1) FIGO 2009, (2) 2023 molecular‐agnostic and (3) 2023 molecular‐informed stages to 404 fully staged and molecularly classified patients with EC. Disease‐specific and progression/relapse‐free survival were analysed via the Kaplan–Meier method and compared with log‐rank testing; 118 of 252 (47%) FIGO 2009 stage I patients were upstaged based on histopathological findings alone. Stage I/II subgroup survival distribution analysis showed a worse prognosis in FIGO 2023 IIB and IIC patients. In the molecular‐informed FIGO 2023 system, three of 15 (20%) POLE‐mutated stage I/II cases were downstaged from FIGO 2009 and eight (53%) were downstaged from molecular‐agnostic FIGO 2023. Fifty‐one of 60 (85%) p53‐abnormal tumours were upstaged from the FIGO 2009, whereas 13 of 60 (22%) were upstaged from the 2023 molecular‐agnostic stage. Molecular classification improved prognostic stratification for both 2009 and 2023 FIGO systems. Conclusions: Downstaging based on POLE mutation more accurately represents patient outcomes. However, in the absence of known POLE status, applying molecular‐agnostic FIGO 2023 criteria for stage I/II disease should be conducted with caution. For aggressive histotypes, additionally reporting FIGO 2009 stage should be considered. Upstaging based on substantial lymphovascular space invasion, aggressive histotype with any myometrial invasion and abnormal p53 improves prognostic discernment. Further subdivisions within stage I/II provide minimal additional prognostic information. [ABSTRACT FROM AUTHOR]

Purpose: Based on the comparison of ramucirumab monoclonal antibody with control treatments in randomized controlled trials, this study aims to elucidate the role of ramucirumab monoclonal antibody in cancer therapy and its potential side effects, providing scientific evidence for clinical treatment. Methods: PubMed, Embase, Cochrane, and Web of Science were searched systematically to obtain the trials on ramucirumab in the treatment of gastric or gastroesophageal junction (GEJ) adenocarcinoma up to April 13, 2023. We included randomized controlled trials (RCTs) evaluating the efficacy and safety of ramucirumab as monotherapy and in combination with other chemotherapy agents as interventions for treating gastric or gastroesophageal junction (GEJ) adenocarcinoma. Results: After screening 2200 studies, we finally included 8 eligible studies (involving a total of 3,283 participants). Meta-analysis results showed that compared to the control group, ramucirumab monotherapy significantly improved overall survival (OS) (hazard ratio [HR] = 0.77, 95% confidence interval [CI] [0.67, 0.89]) and progression-free survival (PFS) (HR = 0.48, 95% CI [0.40, 0.58]). Similar results were obtained for ramucirumab combined with paclitaxel. In the treatment combining ramucirumab with paclitaxel, compared to monotherapy, three severe adverse reactions (grade ≥ 3) were observed with significantly increased risks (OR > 2). These include proteinuria (OR = 5.37, 95% CI [1.22, 23.54]), hypertension (OR = 4.02, 95% CI [2.63, 6.14]), and gastrointestinal perforation (OR = 4.64, 95% CI [1.00, 21.60]). Subgroup analysis further indicated that ramucirumab is effective in both non-East Asian and East Asian populations, with East Asian patients more prone to developing proteinuria, while having a lower incidence of hypertension. Additionally, ramucirumab demonstrated comparable efficacy between first-line and second-line treatments, with a higher incidence of proteinuria observed in second-line therapy. Conclusion: Ramucirumab significantly improves the prognosis of patients with gastric or gastroesophageal junction adenocarcinoma. When used in combination with paclitaxel, close monitoring of adverse reactions such as proteinuria (especially in East Asian populations), hypertension (especially in non-East Asian populations), and gastrointestinal perforation is essential.

The expression of cancer stem cell (CSC) markers adversely affect the survival prognosis of patients with hepatocellular carcinoma (HCC), but it is not clear which cancer stem cell marker has the best predictive effect on the survival prognosis and diagnostic value indicators of patients with HCC. Therefore, the present study performed a network meta-analysis to compare the prognostic and diagnostic value of the expressions of several CSC markers for patients with HCC and to identify the most efficient CSC marker. Studies on the associations of positive CSC markers with the overall survival (OS) rate, disease-free survival (DFS) rate, recurrence-free survival (RFS) rate, recurrence rate, differentiation, microvascular invasion and metastasis in patients with HCC were included in the network meta-analysis following searches on the PubMed, Embase, Elsevier and The Cochrane Library databases from January 1, 2013 to November 17, 2023. The Quality Assessment of Diagnostic Accuracy Studies-2 tool was used to assess the quality assessment of studies, and R (version 4.3.1), Stata (version 15.0) and Review Manager (version 5.3) were used for analysis. A total of 37 studies involving 3,980 participants were included. For patients with HCC, simultaneous positivity of cytokeratin 19 (CK19) and epithelial cell adhesion molecule (EpCAM) was the strongest predictor of the OS rate [surface under the cumulative ranking curve (SUCRA), 78.65%], positive keratin 19 (K19) was the strongest predictor of the RFS and DFS rates (SUCRA, 98.93 and 84.95%, respectively), and simultaneous positivity of EpCAM and cluster of differentiation (CD)90 was the strongest predictor of the recurrence rate (SUCRA, 5.61%). In addition, positivity of CD56, K19 and CD133 had the best diagnostic efficacy for poor differentiation [superiority index, 7.4498; 95% confidence interval (CI): 0.3333, 13.0000], microvascular invasion (superiority index, 8.4777; 95% CI: 0.2308, 17.0000), and metastasis (superiority index, 5.6097; 95% CI: 0.3333, 11.0000), respectively. In conclusion, no single CSC marker possessed the best predictive effect on all indexes of survival prognosis and diagnosis of patients with HCC. In terms of survival prognosis, simultaneous positivity of CK19 and EpCAM demonstrated the strongest predictive effect on the OS rate, suggesting an association with a low OS rate in patients with HCC; positive K19 revealed the strongest predictive effect on the RFS rate and DFS rate, suggesting an association with low RFS and DFS rates in patients with HCC; and simultaneous positivity of EpCAM and CD90 had the strongest predictive effect on the recurrence rate, suggesting a high recurrence rate in patients with HCC patients. In terms of diagnostic value, CD56, K19 and CD133 were the strongest predictors of poor differentiation, microvascular invasion and metastasis, respectively. In the future, well-designed randomized controlled trials are required to further confirm these findings. [ABSTRACT FROM AUTHOR]

Head and neck cancer (HNC) is the sixth most common type of cancer worldwide, and head and neck squamous cell carcinoma (HNSCC) accounts for 90% of HNC cases. Furthermore, HNSCC accounts for 400,000 cancer-associated deaths worldwide each year. However, at present there is an absence of a versatile biomarker that can be used for diagnosis, prognosis evaluation and as a therapeutic target for HNSCC. In the present study, bioinformatics analysis was used to assess the relationship between hub genes and the clinical features of patients with HNSCC. The findings from the bioinformatics analysis were then verified using clinical samples and in vitro experiments. A total of 51 overlapping genes were identified from the intersection of differentially expressed genes and co-expressed genes. The top 10 hub genes were obtained from a protein-protein interaction network of overlapping genes. Among the hub genes, only secretoglobin family 1A member 1 (SCGB1A1) was significantly associated with both overall and disease-free survival. Specifically, upregulated SCGB1A1 expression levels were associated with prolonged overall and disease-free survival. Moreover, the SCGB1A1 expression levels were negatively correlated with drug sensitivity. Notably, it was demonstrated that SCGB1A1 was involved in tumor immunoreaction by affecting the infiltration of cells and checkpoint regulation of immune cells. Additionally, it was shown that SCGB1A1 regulated multiple key cancer-related signaling pathways, including extracellular matrix receptor interaction, transforming growth factor-β and tumor metabolism signaling pathways. Based on the results of the present study, SCGB1A1 may serve as a novel biomarker for predicting the diagnosis, prognosis and therapeutic effectiveness of certain drugs in patients with HNSCC. Moreover, SCGB1A1 may serve as a potential therapeutic target for the management of HNSCC. [ABSTRACT FROM AUTHOR]

Renal insufficiency and/or chronic kidney disease are common comorbidities in patients with lung cancer, potentially affecting their prognosis. The aim of the present study was to assess the existing evidence on the association between renal insufficiency (RI)/chronic kidney disease (CKD) and the overall survival (OS) and disease-free survival (DFS) of patients with lung cancer (LC). Comprehensive electronic searches in the PubMed, Embase and Scopus databases were performed for observational cohort and case-control studies and randomized controlled trials that investigated the association between RI/CKD and the OS and/or DFS of patients with LC. Random-effect models were used, and the combined effect sizes were reported as either standardized mean differences or relative risks, along with 95% confidence intervals (CI). A total of 10 studies were included. The duration of follow-up in the included studies ranged from 12 months to 5 years. Compared with patients with normal renal function, patients with LC with RI/CKD had worse OS rates [hazard ratio (HR), 1.38; 95% CI, 1.16-1.63] but similar DFS rates (HR, 1.12; 95% CI, 0.75-1.67) at follow-up. Subgroup analysis demonstrated a significant association between poor OS and RI/CKD in patients with stage I/II LC [HR, 1.76; 95% CI, 1.30-2.37] but not in patients with stage III/IV LC [HR, 1.18; 95% CI, 0.91, 1.54]. Furthermore, irrespective of the treatment modality i.e., surgery [HR, 1.78; 95% CI, 1.40-2.27] or medical management [HR, 1.37; 95% CI, 1.25-1.50], RI/CKD was notably associated with a poor OS at follow-up. The findings of the present study underscore the adverse impact of RI/CKD on the long-term survival of patients with LC. [ABSTRACT FROM AUTHOR]

Endocrine therapy has become the fundamental treatment option for hormone receptor-positive (HR+) and receptor tyrosine-protein kinase erbB-2-negative (HER2-) metastatic breast cancer (mBC). While treatments incorporating cyclin-dependent kinase (CDK)4 and 6 inhibitors are more prevalent than ever, comparisons among those regimens are scarce. The aim of the present study was to identify the most effective maintenance treatment for patients with HR+ and HER2- mBC. To this end, databases including PubMed, Embase, Cochrane Library, Scopus and Google Scholar were searched from inception to August, 2023. The endpoints comprised overall survival (OS) and progression free survival (PFS). For dichotomous variants, hazard ratios (HRs) and odds ratios (ORs) were generated, while standard mean difference (SMD) was used for consecutive variants by Bayesian network meta-analysis to make pairwise comparisons among regimens, to determine the optimal therapy. These processes were conducted using Rstudio 4.2.2 orchestrated with STATA 17.0 MP. A total of 16 randomized controlled trials including 7,174 patients with 11 interventions were analyzed. Compared with aromatase inhibitor (AI), palbociclib plus AI (PalboAI) exhibited a significantly longer PFS up to the 36th month of follow-up [HR=1.7; 95% credible interval, 1.36-2.16], including on the 3rd [OR=2.22; 95% confidence interval (CI), 1.10-4.47], 6th (OR=2.39; 95% CI, 1.21-4.69), 12th (OR=1.94; 95% CI, 1.34-2.79), 18th (OR=2.38; 95% CI, 1.65-3.44), 24th (OR=2.39; 95% CI, 1.67-3.43), 30th (OR=2.10; 95% CI, 1.62-2.74) and 36th (OR=2.66; 95% CI, 1.37-5.18) month of follow-up. Additionally, abemaciclib plus fulvestrant exhibited significant effects compared with AI alone between 12 and 36 months. Ribociclib plus fulvestrant, ribociclib plus AI and dalpiciclib plus AI exerted significant effects compared with AI alone between 12 and 30 months. Considering the effect on OS and PFS together with adverse reactions, safety, medical compliance and route of administration, PalboAI was found to be the optimal treatment for HR+/HER2-mBC. However, additional head-to-head clinical trials are warranted to confirm these findings. [ABSTRACT FROM AUTHOR]

Recent studies have explored the prognostic role of the C-reactive protein to albumin ratio (CAR) in patients with bile duct cancer (BTC), but the results have been inconsistent. This study aimed to provide insight into the prognostic significance of the CAR in BTC prior to treatment using a meta-analysis. Summarized hazard ratios (HRs) or odds ratios (ORs) and 95% confidence intervals (CIs) were calculated for prognosis and clinicopathological features using fixed or random effects models. Fourteen studies with a total of 1,543 subjects were included in this meta-analysis. Elevated CAR was significantly associated with poor overall survival (HR = 2.17, 95% CI = 1.81–2.60, P < 0.001) and decreased disease-free survival or recurrence-free survival (HR = 2.53, 95% CI = 1.98–3.25, P < 0.001) in BTC. In addition, high CAR was significantly associated with the presence of lymph node metastasis (OR = 1.54, 95% CI = 1.12– 2.13, P = 0.008), bile duct invasion (OR = 2.64, 95% CI = 1.54–4.54, P < 0.001), and tumor stages III–IV (OR = 3.11, 95% CI = 1.05–9.20, P = 0.040). However, there was no significant association between CAR and sex, microvascular invasion, or resection. An elevated CAR was significantly related to worse long-term and short-term survival and advanced clinicopathological features of BTC. CAR could serve as a valuable, noninvasive prognostic marker in patients with BTC. [ABSTRACT FROM AUTHOR]

This study aimed to evaluate the efficacy of local ablative therapy (LAT) combined with pembrolizumab in patients with synchronous oligometastatic non-small cell lung cancer (NSCLC) and to identify patients who would most benefit from LAT. We retrospectively identified patients who received diagnosis of synchronous oligometastatic NSCLC (≤5 metastatic lesions and ≤3 organs involved) and were treated with first-line pembrolizumab between January 2017 and December 2022. Patients who underwent LAT, including surgery or radiation therapy at all disease sites, were compared with those who did not undergo LAT. A recursive partitioning analysis (RPA) model was developed using prognostic factors for progression-free survival (PFS). Among the 258 patients included, 78 received LAT with pembrolizumab, and 180 received pembrolizumab alone. The median follow-up duration was 15.5 months (range, 3.0-71.2 months). In the entire cohort, LAT was independently associated with significantly improved PFS (hazard ratio [HR], 0.64; P =.015) and overall survival (OS) (HR, 0.61; P =.020). In the propensity score-matched cohort (N = 74 in each group), the median PFS was 19.9 months and 9.6 months, respectively (P =.003), and the median OS was 42.2 months and 20.5 months, respectively (P =.045), for the LAT and non-LAT groups. Based on the RPA model, incorporating the number of metastatic lesions, performance status, and programmed cell death-ligand 1 expression level, patients were stratified into 3 risk groups with distinct PFS. LAT significantly improved PFS and OS in the low- and intermediate-risk groups; however, no difference was observed in the high-risk group. LAT was more effective as a consolidative treatment after pembrolizumab initiation than as an upfront therapy. LAT combined with pembrolizumab was associated with higher PFS and OS compared with pembrolizumab alone in selected patients with synchronous oligometastatic NSCLC. The RPA model could serve as a valuable clinical tool for identifying appropriate patients for LAT. [ABSTRACT FROM AUTHOR]

This phase 1/2 study aimed to evaluate the safety and preliminary efficacy of combining disulfiram and copper (DSF/Cu) with radiation therapy (RT) and temozolomide (TMZ) in patients with newly diagnosed glioblastoma (GBM). Patients received standard RT and TMZ with DSF (250-375 mg/d) and Cu, followed by adjuvant TMZ plus DSF (500 mg/d) and Cu. Pharmacokinetic analyses determined drug concentrations in plasma and tumors using high-performance liquid chromatography-mass spectrometry. Thirty-three patients, with a median follow-up of 26.0 months, were treated, including 12 IDH -mutant, 9 NF1 -mutant, 3 BRAF -mutant, and 9 other IDH -wild-type cases. In the phase 1 arm, 18 patients were treated; dose-limiting toxicity probabilities were 10% (95% CI, 3%-29%) at 250 mg/d and 21% (95% CI, 7%-42%) at 375 mg/d. The phase 2 arm treated 15 additional patients at 250 mg/d. No significant difference in overall survival or progression-free survival was noted between IDH - and NF1 -mutant cohorts compared with institutional counterparts treated without DSF/Cu. However, extended remission occurred in 3 BRAF -mutant patients. Diethyl-dithiocarbamate-copper, the proposed active metabolite of DSF/Cu, was detected in plasma but not in tumors. The maximum tolerated dose of DSF with RT and TMZ is 375 mg/d. DSF/Cu showed limited clinical efficacy for most patients. However, promising efficacy was observed in BRAF -mutant GBM, warranting further investigation. [ABSTRACT FROM AUTHOR]

The role of stereotactic radiosurgery (SRS) in the management of grade 2 and 3 meningiomas is not well elucidated. Unfortunately, local recurrence rates are high, and guidelines for management of recurrent disease are lacking. To address this knowledge gap, we conducted STORM (Salvage Stereotactic Radiosurgery for Recurrent WHO Grade 2 and 3 Meningiomas), a multicenter retrospective cohort study of patients treated with primary SRS for recurrent grade 2 and 3 meningiomas. Data on patients with recurrent grade 2 and 3 meningioma treated with SRS at first recurrence were retrospectively collected from 8 academic centers in the United States. Patients with multiple lesions at the time of initial diagnosis or more than 2 lesions at the time of first recurrence were excluded from this analysis. Patient demographics and treatment parameters were extracted at time of diagnosis, first recurrence, and second recurrence. Oncologic outcomes, including progression-free survival (PFS) and overall survival, as well as toxicity outcomes, were reported at the patient level. From 2000 to 2022, 108 patients were identified (94% grade 2, 6.0% grade 3). A total of 106 patients (98%) had upfront surgical resection (60% gross-total resection) with 18% receiving adjuvant radiation therapy (RT). Median time to first progression was 2.5 years (IQR, 1.34-4.30). At first recurrence, patients were treated with single or fractionated SRS to a median marginal dose of 16 Gy to a maximum of 2 lesions (87% received single-fraction SRS). The median follow-up time after SRS was 2.6 years. The 1-, 2-, and 3-year PFS was 90%, 75%, and 57%, respectively, after treatment with SRS. The 1-, 2-, and 3-year overall survival was 97%, 94%, and 92%, respectively. In the multivariable analysis, grade 3 disease (HR, 6.80; 95% CI, 1.61-28.6), male gender (HR, 3.48; 95% CI, 1.47-8.26), and receipt of prior RT (HR, 2.69; 95% CI, 1.23-5.86) were associated with worse PFS. SRS dose and tumor volume were not correlated with progression. Treatment was well tolerated, with a 3.0% incidence of grade 2+ radiation necrosis. This is the largest multicenter study to evaluate salvage SRS in recurrent grade 2 and 3 meningiomas. In this select cohort of patients with primarily grade 2 meningioma with a potentially more favorable natural history of delayed, localized first recurrence amenable to salvage SRS, local control rates and toxicity profiles were favorable, warranting further prospective validation.

We present the final analyses of tumor dynamics and their prognostic significance during a 6-week course of concurrent chemoradiotherapy for glioblastoma in the Glioblastoma Longitudinal Imaging Observational study. This is a prospective serial magnetic resonance imaging study in 129 patients with glioblastoma who had magnetic resonance imaging obtained at radiation therapy (RT) planning (F0), fraction 10 (F10), fraction 20 (F20), and 1-month post-RT. Tumor dynamics assessed included gross tumor volume relative to F0 (V rel) and tumor migration distance (d migration). Covariables evaluated included: corpus callosum involvement, extent of surgery, O6-methylguanine-DNA-methyltransferase methylation, and isocitrate dehydrogenase mutation status. The median V rel were 0.85 (range, 0.25-2.29) at F10, 0.79 (range, 0.09-2.22) at F20, and 0.78 (range, 0.13-4.27) at 1 month after completion of RT. The median d migration were 4.7 mm (range, 1.1-20.4 mm) at F10, 4.7 mm (range, 0.8-20.7 mm) at F20, and 6.1 mm (range, 0.0-45.5 mm) at 1 month after completion of RT. Compared with patients who had corpus callosum involvement (n = 26), those without corpus callosum involvement (n = 103) had significant V rel reduction at F20 (P =.03) and smaller d migration at F20 (P =.007). Compared with patients who had biopsy alone (n = 19) and subtotal resection (n = 71), those who had gross total resection (n = 38) had significant V rel reduction at F10 (P =.001) and F20 (P =.001) and a smaller d migration at F10 (P =.03) and F20 (P =.002). O6-Methylguanine-DNA-methyltransferase methylation and isocitrate dehydrogenase mutation status were not significantly associated with tumor dynamics. The median progression-free survival and overall survival (OS) were 8.5 months (95% CI, 6.9-9.9) and 20.4 months (95% CI, 17.6-25.2). In multivariable analyses, patients with V rel ≥ 1.33 at F10 had worse OS (hazard ratio [HR], 4.6; 95% CI, 1.8-11.4; P =.001), and patients with d migration ≥ 5 mm at 1-month post-RT had worse progression-free survival (HR, 1.76; 95% CI, 1.08-2.87) and OS (HR, 2.2; 95% CI, 1.2-4.0; P =.007). Corpus callosum involvement and extent of surgery are independent predictors of tumor dynamics during RT and can enable patient selection for adaptive RT strategies. Significant tumor enlargement at F10 and tumor migration 1-month post-RT were associated with poorer OS. [ABSTRACT FROM AUTHOR]

Background: The anti-PD-L1 antibody durvalumab has been approved for use in first-line advanced biliary duct cancer (ABC). So far, predictive biomarkers of efficacy are lacking. Methods: ABC patients who underwent gemcitabine-based chemotherapy with or without durvalumab were retrospectively enrolled, and their baseline clinical pathological indices were retrieved from medical records. Overall (OS) and progression free survival (PFS) were calculated and analyzed. The levels of peripheral biomarkers from 48 patients were detected with assay kits including enzyme-linked immunosorbent assay. Genomic alterations in 27 patients whose tumor tissues were available were depicted via targeted next-generation sequencing. Results: A total of 186 ABC patients met the inclusion criteria between January 2020 and December 2022 were finally enrolled in this study. Of these, 93 patients received chemotherapy with durvalumab and the rest received chemotherapy alone. Durvalumab plus chemotherapy demonstrated significant improvements in PFS (6.77 vs. 4.99 months; hazard ratio 0.65 [95% CI 0.48–0.88]; P = 0.005), but not OS (14.29 vs. 13.24 months; hazard ratio 0.91 [95% CI 0.62–1.32]; P = 0.608) vs. chemotherapy alone in previously untreated ABC patients. The objective response rate (ORR) in patients receiving chemotherapy with and without durvalumab was 19.1% and 7.8%, respectively. Pretreatment sPD-L1, CSF1R and OPG were identified as significant prognosis predictors in patients receiving durvalumab. ADGRB3 and RNF43 mutations were enriched in patients who responded to chemotherapy plus durvalumab and correlated with superior survival. Conclusion: This retrospective real-world study confirmed the clinical benefit of durvalumab plus chemotherapy in treatment-naïve ABC patients. Peripheral sPD-L1 and CSF1R are promising prognostic biomarkers for this therapeutic strategy. Presence of ADGRB3 or RNF43 mutations could improve the stratification of immunotherapy outcomes, but further studies are warranted to explore the underlying mechanisms. [ABSTRACT FROM AUTHOR]

• Enfortumab vedotin/pembrolizumab shows highest overall survival (HR 0.47, 95% CrI: 0.38–0.58). • Avelumab monotherapy significantly improves survival (HR 0.69, 95% CrI: 0.56–0.86). • Combination therapy enfortumab/pembrolizumab enhances progression-free survival (HR 0.45, 95% CrI: 0.38–0.54). • Avelumab monotherapy exhibits highest odds of overall response rate. • PD-L1 positive and negative patients both might benefit from the analyzed therapies. Metastatic urothelial carcinoma (muC) has historically had few effective therapeutic options. Recently, immune checkpoint inhibitors (ICIs), were introduced as therapeutic options for cisplatin-ineligible patients, however, direct head-to-head trials comparing these treatments are lacking. To address this gap, this study employs a Bayesian framework to indirectly compare the performance of ICIs as first-line agents for muC. A systematic review was performed to identify randomized controlled trials evaluating different ICI for mUC. Data was inputted into Review Manager 5.4 for pairwise meta-analysis. Data was then used to build a network in R Studio. These networks were used to model 200,000 Markov Chains via MonteCarlo sampling. The results are expressed as hazard ratios (HR) with 95% credible intervals (CrI). Six studies with 5,449 patients were included, 3,255 received ICI monotherapy or combination. Moreover, a total of 3,006 had PD-L1 positive tumors and 2,362 were PD-L1 negative. Median overall survival (OS) ranged from 12.1 to 31.5 months across the studies, with the combination of enfortumab vedotin and pembrolizumab demonstrating the most substantial reduction in the risk of death (HR 0.47 [95% CrI: 0.38, 0.58]), followed by avelumab monotherapy (HR 0.69 [95% CrI: 0.56, 0.86]). The limitations of this network meta-analysis include variability in study follow-up duration, lack of standardized methods for assessing PD-L1 positivity, and potential bias introduced by control arms with poorer survival outcomes across included trials. The enfortumab vedotin/pembrolizumab combination significantly improved survival and response rates. Avelumab showed notable single-agent activity. These findings provide a valuable framework to guide clinical decision-making and highlight priority areas for future research, including biomarker refinement and novel combination strategies to enhance antitumor immunity in this challenging malignancy.

This study was designed to investigate the demographics, treatment patterns, and clinical outcomes of patients newly diagnosed with high-grade serous ovarian cancer (HGSOC) in 3 medical centers in Taiwan before the integration of poly (ADP-ribose) polymerase inhibitors in clinical practice. A retrospective analysis was conducted on data from patients diagnosed with HGSOC between January 2014 and December 2018 and followed-up for a minimum of 12 months after diagnosis. Descriptive statistics were used to analyze the data, while survival rates were evaluated using the Kaplan‒Meier method. There were 251 patients included in the analysis, and 98.8% received platinum plus paclitaxel chemotherapy (PPCT). Primary cytoreductive surgery (PCS) and interval debulking surgery (IDS) were performed in 78.9% and 17.1% of patients, respectively. The percentage of optimal surgery was higher in the IDS cohort than in the PCS cohort (83.8% vs. 53.6%). Bevacizumab was used as initiation therapy in 16.7% of patients, and maintenance therapy was administered in 6.8%. Advanced age, IDS, and suboptimal surgery were independent poor prognostic factors associated with lower overall survival (OS). Patients with optimal surgery had significantly lower OS and progression-free survival in the IDS cohort than in the PCS cohort. The predictive accuracy was good for OS at the 1-year follow-up. Advanced age, IDS, and residual disease are associated with poor OS in patients with HGSOC. Compared to PCS, IDS provides a higher likelihood of optimal surgery but results in a lower probability of survival for patients with HGSOC in Taiwan. [ABSTRACT FROM AUTHOR]

The aim of this study was to characterize the clinicopathological features and prognostic factors of T1/2 size (<4 cm) gingival squamous cell carcinoma (SCC) and to verify the impact of bone invasion. This was a single-centre, retrospective cohort study involving 206 patients with gingival SCC (maxilla or mandible), treated between 2000 and 2020. The patients were divided into three subgroups based on tumour size and bone invasion. The 5-year overall survival (OS) and disease-free survival (DFS) were 80.6% and 67.6%, respectively. Histological differentiation, advanced T stage, positive resection margin, bone invasion, and postoperative adjuvant therapy were associated with a poor prognosis (P < 0.05). Multivariate Cox analysis indicated that only histological differentiation (hazard ratio (HR) 2.68, P = 0.007) and bone invasion (HR 2.08, P = 0.036) were significantly associated with DFS. Bone invasion was observed in 145 (70.4%) patients, of whom 43 (20.9%) had a T1/2 size tumour. The subgroup with bone invasion and T1/2 size showed significantly worse OS and DFS when compared to the subgroup without bone invasion and similar or worse survival when compared to the subgroup with bone invasion and T3/T4 size. Histological differentiation and bone invasion were poor prognostic factors for gingival SCC, even in cases with small-sized tumours. For suspected bone invasion in small-sized tumours, an adequate bone margin is necessary and postoperative adjunctive therapy needs to be considered. [ABSTRACT FROM AUTHOR]

Atezolizumab plus bevacizumab is a standard of care, first-line therapy for advanced hepatocellular carcinoma (HCC). Myeloid and T regulatory cells are key immunosuppressive cell types within the hepatic tumor microenvironment associated with clinical resistance to atezolizumab and bevacizumab therapy for HCC and overall poor prognosis. Therapeutic targeting of TIGIT, which is highly expressed in these cells, with tiragolumab may overcome the immunosuppressive environment and improve clinical benefit, a hypothesis supported by positive efficacy signals in the Phase Ib/II MORPHEUS-Liver study. This paper describes the rationale and design of IMbrave152/SKYSCRAPER-14, a randomized, double-blind, placebo-controlled Phase III study comparing atezolizumab and bevacizumab with tiragolumab or placebo in patients with HCC and no prior systemic treatment. Clinical Trial Registration: NCT05904886 (ClinicalTrials.gov) Plain Language Summary This research study is designed to test a new treatment combination for liver cancer, specifically for patients whose cancer cannot be removed with surgery or has spread. The treatment involves three medications: atezolizumab, bevacizumab and tiragolumab. Atezolizumab and bevacizumab are already used together as a standard treatment for liver cancer. Tiragolumab is designed to block the TIGIT receptor, which is normally involved in holding back the immune cells that would attack the tumor. Because tiragolumab may restore the immune response against the tumor, adding tiragolumab might make the treatment more effective. The study is being done worldwide and includes patients who have not received any previous systemic treatment for their advanced liver cancer. Patients participating in the study will be randomly placed into two groups. One group will receive the new combination of three medications, while the other group will receive the standard treatment of two medications plus a placebo (a treatment with no active ingredient). The main goal is to see if the new combination helps patients live longer and slows the cancer's growth compared with the standard treatment. Safety and how patients feel during the treatment are also important parts of the study. Tweetable Abstract IMbrave152/SKYSCRAPER-14: New Phase III trial tests atezolizumab, bevacizumab & tiragolumab in advanced HCC, aiming to revolutionize treatment outcomes. #HCCResearch #OncologyInnovation Article highlights Advanced hepatocellular carcinoma treatment Atezolizumab in combination with bevacizumab has become the standard first-line therapy for advanced hepatocellular carcinoma (HCC). The immunosuppressive hepatic tumor microenvironment may limit the clinical activity of this combination in patients with HCC. TIGIT, a protein often found at high levels within these immunosuppressive cells, is a potential therapeutic target to overcome this resistance. Tiragolumab is an agent that inhibits TIGIT, suggesting a possible improvement in clinical outcomes when combined with the existing therapy. IMbrave152/SKYSCRAPER-14 trial rationale The randomized Phase III trial (NCT05904886) is designed to compare the efficacy and safety of the addition of tiragolumab to the current atezolizumab and bevacizumab regimen for HCC. The trial is designed to confirm efficacy signals from the Phase Ib/II MORPHEUS-Liver study, testing the hypothesis that targeting TIGIT with tiragolumab can enhance treatment response. Study design & eligibility Approximately 650 participants with no prior systemic treatment will be assigned to receive either the triple combination of atezolizumab, bevacizumab and tiragolumab or the standard dual therapy plus placebo. Participants will be randomly divided into two groups with stratification based on geographic region, disease progression, α-fetoprotein levels and HCC etiology. Treatment & trial objectives Patients will be administered intravenous doses of the treatment every three weeks, with outcomes measured in terms of progression-free survival and overall survival. Secondary end points include safety, efficacy, pharmacokinetics, immunogenicity and quality-of-life assessments. Preliminary results & safety profile The MORPHEUS-Liver trial indicated improved outcomes with the addition of tiragolumab to the existing atezolizumab and bevacizumab treatment, suggesting a well-tolerated safety profile with manageable adverse events. Conclusions & implications for hepatocellular carcinoma treatment IMbrave152/SKYSCRAPER-14 aims to establish whether the addition of tiragolumab can redefine the standard of care for unresectable HCC. This trial's findings could significantly impact the therapeutic landscape for HCC, addressing a critical unmet medical need [ABSTRACT FROM AUTHOR]

Aim: Patient preferences for the features of targeted chronic lymphocytic leukemia (CLL) therapies may differ. Materials & methods: A discrete-choice experiment (DCE) survey was administered to 229 respondents recruited through the CLL Society. Results: Respondents placed most importance on increasing the chance of progression-free survival (PFS) at 2 years from 70 to 90% and confirming results with measurable residual disease (MRD) testing instead of routine testing. Respondents also preferred daily oral administration over intravenous infusion every 4 weeks, fixed-duration treatments over treat-to-progression treatments and treatments with lower side effect risks. Reducing risk of tumor lysis syndrome was least important relative to changes in other attributes. Conclusion: The combination of improving PFS combined with confirming results using MRD testing was more important than changes in all other study attributes included in the DCE. Results from this study can help inform shared decision-making when selecting therapies for CLL. Plain Language Summary Several targeted treatments are available for people with chronic lymphocytic leukemia (CLL). These treatments target specific proteins present in CLL cancer cells. They differ in how long they keep cancer from progressing, how the results are measured and the side effects they cause. Some targeted CLL treatments are taken as a daily pill, and others are given by intravenous infusion. Some targeted treatments are given for a fixed amount of time, and others are given until CLL progresses. We surveyed 229 US patients with CLL to understand what features they most value in a targeted CLL treatment. Survey participants were recruited through the CLL Society, a nonprofit organization devoted to education, support, advocacy and research for the CLL community. Survey results indicated that participants placed the most importance on increasing the chance that the cancer would not progress after 2 years from 70 to 90% and confirming results with measurable residual disease testing (which can detect minute levels of leukemia cells) instead of routine testing. Participants also preferred taking a pill every day over receiving an intravenous infusion every 4 weeks and preferred treatments given for a fixed amount of time over treatments given until CLL progresses. Participants preferred treatments with lower chances of tumor lysis syndrome (a potentially organ-damaging condition that may result following treatment), irregular heartbeat and fatigue. It is important for doctors to understand the treatment features that matter to people living with CLL so that they can work with patients individually to choose the right treatment. Tweetable Abstract Patients with CLL prioritize the chance of progression-free survival at 2 years and confirming results with measurable residual disease when considering the attributes of targeted CLL therapies. To quantify respondents' preferences for attributes associated with chronic lymphocytic leukemia (CLL) treatments, a web-based discrete-choice experiment (DCE) survey was developed and administered to respondents recruited through the CLL Society. Respondents (N = 229) answered 12 DCE questions, each offering a choice between two hypothetical treatment profiles defined by seven attributes with varying levels; data were analyzed using a random-parameters logit model. Respondents placed the most importance on increasing the chance of progression-free survival (PFS) at 2 years from 70 to 90% and confirming results with measurable residual disease (MRD) testing instead of routine testing. Respondents also preferred daily oral administration over intravenous infusion every 4 weeks, treatments with a fixed duration over treat-to-progression treatments, and treatments with a lower risk of side effects; reducing the risk of tumor lysis syndrome (TLS) was least important relative to changes in the other study attributes. Respondents were willing to accept a >3% risk of TLS, the largest risk presented in the survey, in exchange for almost all improvements in chance of PFS, duration of treatment and mode of administration shown in the survey. Confirmation with MRD testing was more important to respondents when the chance of achieving PFS was lower (70%) than when it was higher (90%). [ABSTRACT FROM AUTHOR]

Objective: This study analyzes the development, benefits, trial evidence, and price of new breast cancer drugs with US Food and Drug Administration (FDA) approval. Methods: We identified 26 drugs with 42 FDA-approved indications for early and metastatic breast cancer (2000–2023). Data were collected from FDA labels, clinicaltrials.gov, and Medicare and Medicaid. Overall survival (OS) and progression-free survival (PFS) hazard ratios (HRs) and tumor response's relative risk (RR) alongside objective response rate (ORR) were meta-analyzed. Results: The median development time for breast cancer drugs was 7.8 years (95% CI 6.2–10.8). 26% of treatments were considered innovative ("first-in-indication") with 88% acting via a targeted mechanism. 64% were small molecules, 19% antibodies, and 18% antibody-drug conjugates. 38% were approved for HR + and 31% for HER2 + breast cancer. 6 indications were for early and 36 for metastatic breast cancer. Indications utilized FDA's special programs: orphan (2%), fast track (24%), accelerated approval (19%), priority review (74%), breakthrough therapy (44%). Approval was predominantly supported by phase 3 trials (88%) of randomized controlled design (66%), enrolling a median of 585 patients (IQR 417–752) at 181 centers (IQR 142–223) across 19 countries (IQR 17–20). New drugs' HR were 0.78 for OS (95% CI 0.74–0.82) and 0.59 for PFS (95% CI 0.54–0.64) with a RR for tumor response of 1.61 (95% CI 1.46–1.76). Median improvements of OS were 2.8 months (IQR 1.8–5.8) and PFS were 4.4 months (IQR 2.2–7.1). In single-arm trials, the average ORR was 31% (95% CI 10–53). In meta-regressions, the correlation between OS/PFS was 0.34 (p = 0.031) and OS/response was 0.01 (p = 0.435). 60% of treatments had a 'high-value' ESMO-MCBS score with 14% demonstrating improvements in quality of life. The median price was $16,013 per month (95% CI 13,097–17,617). There was no association between prices and patient benefit. The median value per life year gained was $62,419 (IQR 25,840–86,062). Conclusions: Over the past two decades, the development of innovative and effective drugs transformed the treatment landscape for breast cancer patients. Yet, investigators and regulators must safeguard that highly-priced new drugs demonstrate improvements in patient-centered clinical endpoints: overall survival and quality of life.

Extranodal marginal zone lymphoma (EMZL) encompasses 70% of cases of marginal zone lymphoma. Frontline bendamustine and rituximab (BR) were derived from trials involving other indolent non-Hodgkin's lymphomas. Only one trial has evaluated frontline BR prospectively in EMZL. This retrospective study reports outcomes among EMZL patients receiving frontline BR. Twenty-five patients were included with a median age of 69 years (40--81). Five (20.0%) patients had stage I/II disease, and 20 (80.0%) had stage III/IV disease. The median number of cycles was 6.0 (3.0--6.0). Maintenance rituximab was administered to 10 (41.7%) individuals. Overall response rate (ORR) was 100.0% (60.0% complete response, 40.0% partial response). Medians of overall survival and progression-free survival were not reached. The estimated 2-year progression-free survival was 85.2% and overall survival was 100.0%. Four (16.6%) patients had infections related to treatment; 3 (12.0%) transformed to diffuse large B-cell lymphoma; 5 (20.8%) had a relapse or progression of EMZL; and 3 (12.0%) died unrelated to BR. BR is an efficacious and well-tolerated front-line regimen for EMZL with response data consistent with existing literature. [ABSTRACT FROM AUTHOR]

Cadonilimab is a bispecific antibody targeting PD-1 and CTLA-4, which has shown substantial clinical benefits in advanced cervical cancer. In the COMPASSION-16 trial, we aimed to evaluate the addition of cadonilimab to first-line standard chemotherapy in persistent, recurrent, or metastatic cervical cancer. In this randomised, double-blind, multicentre, placebo-controlled phase 3 trial, women aged 18–75 years across 59 clinical sites in China with previously untreated persistent, recurrent, or metastatic cervical cancer were randomly assigned (1:1) to receive cadonilimab (10 mg/kg) or placebo plus platinum-based chemotherapy with or without bevacizumab every 3 weeks for six cycles, followed by maintenance therapy every 3 weeks for up to 2 years. Randomisation was performed centrally through an interactive web-response system. Stratification factors were the use of bevacizumab (yes or no) and previous concurrent chemoradiotherapy (yes or no). The dual primary outcomes were progression-free survival as assessed by blinded independent central review and overall survival in the full analysis set. This study is registered with ClinicalTrials.gov , NCT04982237 ; the study has completed enrolment and is ongoing for treatment and follow-up. 445 eligible women were enrolled between Sept 11, 2021, and June 23, 2022. Median progression-free survival was 12·7 months (95% CI 11·6–16·1) in the cadonilimab group and 8·1 months (7·7–9·6) in the placebo group (hazard ratio 0·62 [95% CI 0·49–0·80], p<0·0001); median overall survival was not reached (27·0 months to not estimable) versus 22·8 months (17·6–29·0), respectively (hazard ratio 0·64 [0·48–0·86], p=0·0011). The most common grade 3 or higher adverse events were decreased neutrophil count, decreased white blood cell count, and anaemia. The addition of cadonilimab to first-line standard chemotherapy significantly improved progression-free survival and overall survival with a manageable safety profile in participants with persistent, recurrent, or metastatic cervical cancer. The data support the use of cadonilimab plus chemotherapy as an efficacious first-line therapy in persistent, recurrent, or metastatic cervical cancer. Akeso Biopharma. [ABSTRACT FROM AUTHOR]

Background: Docetaxel (DOC) and ramucirumab (RAM) is one of the most effective regimens for advanced non-small cell lung cancer (NSCLC) treatment. In our previous study, baseline anemia was identified as a preventive factor against the development of severe adverse effects during the first treatment cycle. It was hypothesized that anemia directly promotes tumor angiogenesis, leading to the elevation of RAM efficacy with increased DOC delivery to tumors, while reducing DOC delivery to other organs, potentially mitigating severe adverse effects. If this hypothesis is correct, patients with baseline anemia may have better clinical outcomes than those with normal hemoglobin levels. In this study, we aimed to investigate the effect of baseline anemia on the efficacy of DOC + RAM in treating advanced NSCLC in a real-word setting. Methods: Patients with advanced NSCLC receiving DOC + RAM (n = 72) were retrospectively assessed. They were categorized into a control group with normal baseline hemoglobin levels and an anemia group with baseline anemia. The primary endpoint was progression-free survival (PFS) evaluation. Results: Patients in the anemia group had a significantly shorter PFS than that of patients in the control group (median PFS: 3.2 and 6.2 months; 95% confidence interval [CI]: 2.2–4.8 and 4.3–9.9 months, respectively;P = 0.008). In addition, the disease control rate in the anemia group was 65.8%, which was significantly lower than that in the control group (93.6%; P = 0.007). Overall survival tended to be shorter in patients with anemia than in controls, although the difference was not statistically significant (P = 0.07). Multivariate Cox hazard analysis suggested that baseline anemia was a singular risk factor for poor PFS (adjusted hazard ratio 1.84, 95% CI 1.08–3.13; P = 0.02). The incidence of severe adverse effects did not differ between the two groups. Conclusions: This study suggests that the PFS of patients with anemia treated with DOC + RAM for advanced NSCLC is shorter than that of those without the symptoms. [ABSTRACT FROM AUTHOR]

Purpose: This study compared survival and metastasis occurrence between colorectal neuroendocrine neoplasms (cNEN) and colorectal adenocarcinoma with neuroendocrine differentiation (cNED) and further explored their prognostic factors and treatment indicators. Methods: Patients diagnosed as cNEN and cNED in West China Hospital from January 2009 to December 2020 were enrolled. The diagnosis and metastasis rates were calculated. Univariate and multivariate Cox analyses were conducted for progression-free survival (PFS) in cNEN surgical patients, and generalized linear regression was used for metastatic disease. Result: The study enrolled 435 patients, including 257 neuroendocrine tumors (NET), 52 neuroendocrine carcinomas (NEC), 29 mixed neuroendocrine-non-neuroendocrine neoplasms (MiNEN), and 97 NED patients, of whom 202 received local resection, and 233 received radical resection. Metastasis rates were higher in MiNEN and NEC groups compared to other groups (NED: 28.9%, MiNEN: 58.6%, NEC: 65.4%, NET: 8.6%, p < 0.001). The liver is the main metastatic site in cNEN, whereas cNED metastasized to various sites. For NEC and MiNEN patients, colon location (p = 0.002) and T stage > 2 (p = 0.040) were associated with disease progression separately. Independent risk factors for metastatic NET included tumor grade G2/G3 (p < 0.001), colon location (p = 0.001), size ≥ 1 cm (p = 0.005), and CK20 partial positive (p < 0.001). Conclusion: cNEN show high metastatic capacity and are challenging to diagnose. More aggressive treatment and follow-up strategies are necessary for those patients. NET tumor grade higher than G2, size larger than 1 cm, or located in the colon should be managed with radical surgery. [ABSTRACT FROM AUTHOR]

Purpose: Adrenocortical carcinoma (ACC) poses a significant challenge in healthcare due to its aggressive nature and rarity. Prior reports suggest a poorer prognosis associated with hormone-secreting neoplasms. This study aims to assess the impact of ACC hormonal status on patients' oncologic survival. Methods: A comprehensive literature search of the Medline, Embase, Web of Science, CINAHL, CENTRAL and clinicaltrials.gov databases was undertaken. Utilized data involved Hazard Ratios derived from multivariable analysis in order to minimize exposure to confounding bias. Included studies were subsequently meta-analyzed using a Random effects model. Results: Twelve studies incorporating 4483 patients were included in the quantitative analysis. Hormonally active ACCs comprised 48% of the entire pooled patient cohort and were found to be associated with significantly worse Overall Survival (HR 1.57, 95% Confidence Interval 1.39–1.78, p < 0.001). Disease-Free Survival was comparably impacted (HR 1.32, 95% CI 1.11–1.57, p < 0.001). Furthermore, cortisol secreting ACCs specifically, were also found to be associated with a 48% increase in the hazard of death or disease recurrence. Interstudy statistical heterogeneity was minimal among evaluated outcomes. Conclusions: Hormone-producing ACCs exhibit a poorer prognosis compared to non-secreting counterparts, with a 57% increased risk of death and a 32% increased risk of recurrence. These findings support the hypothesis that hormone production signifies an adverse tumor-specific feature, particularly when leading to hypercortisolemia, indicating an aggressive disease phenotype.

Background: This study aims to assess the clinical efficacy of elective neck irradiation (ENI) in patients with esthesineuroblastoma (ENB), a rare malignant neoplasm, who are clinically node-negative. Methods: We conducted a retrospective analysis of 178 patients newly diagnosed with ENB at our institution between 2009 and 2021. Propensity score matching (PSM) was employed to compare node-negative patients treated with and without ENI. We extensively examined survival outcomes and treatment failure. Results: Of the 178 participants, 149 (83.7%) were lymph node-negative and staged in Modified Kadish A-C. 96 patients underwent ENI treatment, while 53 did not. At baseline, patients who received ENI differed from those who did not in terms of radiotherapy technique, staging, orbital invasion, surgical mode, and chemotherapy. After PSM, 43 pairs were available for analysis. ENI was observed to extend overall survival (OS, 5-year 73.9% vs. 84.0%; 3-year 76.9% vs. 97.1%, p = 0.022), progression-free survival (PFS, 5-year 38.5% vs. 84.6%; 3-year 50.5% vs. 94.5%, p < 0.001) and locoregional relapse-free survival (LRFS, 5-year 42.7% vs. 84.6%, p = 0.023; 3-year 57.3% vs. 94.5%, p < 0.001) in node-negative ENI patients. Failure pattern analyses revealed that ENI, which included level Ib, II, VIIa, significantly reduced the treatment failure rate. Furthermore, ENI did not significantly impact the prognosis of T1-2 patients, indicating potential clinical value of ENI in T3-4 patients. Conclusions: Our findings suggested that ENI decreased regional failure and significantly enhanced LRFS and PFS. ENI may be considered as an integral part of the initial treatment strategy for locally advanced node-negative ENB patients. [ABSTRACT FROM AUTHOR]

Objective: Poly (ADP-ribose) polymerase (PARP) inhibitors such as olaparib and niraparib have shown promise in extending progression-free survival (PFS) in patients with platinum-sensitive recurrent (PSR) epithelial ovarian cancer. In this retrospective study, we aimed to present our own data on the effect of PARP inhibitors on PFS in recurrent epithelial ovarian cancer. Methods: 82 patients diagnosed with PSR epithelial ovarian, tubal, or primary peritoneal cancer between May 2017 and September 2023 were initially enrolled from our hospital. However, 16 patients had prior exposure to PARP inhibitors during primary treatment, and 11 were lost to follow-up. Consequently, the study focused on 55 eligible patients. PFS was compared between patients receiving PARP inhibitor maintenance therapy and those who did not. Results: Among the 55 patients with PSR epithelial ovarian cancer, 18 received olaparib as maintenance therapy, 19 received niraparib, and 18 opted for observation. PARP inhibitor therapy significantly extended PFS (mean 24.0 months) compared to observation (mean 9.0 months, p = 0.0005), regardless of BRCA mutation status (HR = 0.20, 95% CI: 0.08–0.50). Subgroup analysis showed no statistical difference between olaparib and niraparib. Additionally, there was no PFS difference based on BRCA mutation status within both PARP inhibitor groups. Conclusion: Our retrospective study demonstrates that PARP inhibitor maintenance therapy, including olaparib and niraparib, significantly prolongs PFS in patients with PSR epithelial ovarian, tubal, or primary peritoneal cancer, These findings support the broad utilization of PARP inhibitors as a standard maintenance therapy for PSR epithelial ovarian cancer irrespective of BRCA mutation status. Summary: PARP inhibitor maintenance therapy, including olaparib and niraparib, significantly prolongs PFS in patients with PSR epithelial ovarian, tubal, or primary peritoneal cancer, irrespective of BRCA mutation status. PARP inhibitors can be recommended as a standard maintenance therapy for PSR epithelial ovarian cancer. [ABSTRACT FROM AUTHOR]

Recently, several bispecific antibodies (BsAbs) have been approved for the treatment of relapsed multiple myeloma (MM) after early phase trials in heavily pre-treated patients demonstrated high response rates and impressive progression-free survival with monotherapy. These BsAbs provide crucial treatment options for relapsed patients and challenging decisions for clinicians. Evidence on the optimal patient population, treatment sequence, and duration of these therapeutics is unknown and subject to active investigation. While rates of cytokine release syndrome and neurotoxicity appear to be lower with BsAbs than with CAR T-cells, morbidity from infection is high and novel pathways of treatment resistance arise from the longitudinal selection pressure of chronic BsAb therapy. Lastly, a wealth of novel T-cell engagers with unique antibodystructures and antigenic targets are under active investigation with promising early outcome data. In this review, we examine the mechanism of action, therapeutic targets, combinational approaches, sequencing and mechanisms of disease relapse for BsAbs in MM. [ABSTRACT FROM AUTHOR]

Background: The third-line treatment for refractory colorectal cancer (CRC) has limited efficacy. This study aimed to evaluate the safety and efficacy of SHR-8068 (an anti-CTLA-4 antibody), combined with adebrelimab (an anti-PD-L1 antibody), and bevacizumab in refractory non-microsatellite instability-high (MSI-H) or proficient mismatch repair (pMMR) CRC. Method: This study is a prospective, open-label, single-center phase Ib/II clinical trial. Patients with pathologically confirmed pMMR/non-MSI-H metastatic colorectal adenocarcinoma who have failed =2 lines prior standard systemic treatments will be enrolled (n=36). The Ib phase will evaluate two dosing regimens of SHR-8068 in combination therapy (n=9 each dosage): SHR-8068 (1 mg per kilogram, every six weeks, intravenously) or SHR-8068 (4 mg per kilogram, every twelve weeks, intravenously) combined with adebrelimab (1200 mg, every three weeks, intravenously) and bevacizumab (7.5 mg per kilogram, every three weeks, intravenously). The efficacy and adverse events (AEs) of these regimens will be assessed to determine the recommended phase II dose (RP2D) of SHR-8068. Those of RP2D group from the phase Ib will be included in the phase II. The study will go to include 18 additional patients according to the onesample log-rank test design in the phase II. The primary endpoint of the Ib phase is safety, with secondary endpoints including the objective response rate (ORR), progression-free survival (PFS), overall survival (OS), disease control rate (DCR), and quality of life (QOL). The primary endpoint for phase II was PFS, with secondary endpoints including ORR, OS, DCR, safety, and QOL. Identifying biomarkers to predict the efficacy of this regimen is the exploratory study endpoint. Discussion: This proof-of-concept study would provide safety and efficacy signals of this novel combination treatment for the MSS CRCs in the late-line setting. And it may offer new insights on the clinical application of dual immunotherapy combined with anti-angiogenic therapy in the MSS CRC. [ABSTRACT FROM AUTHOR]

Objectives: Numerous studies have investigated the predictive significance of the platelet-to-lymphocyte ratio (PLR) in oral squamous cell carcinoma(OSCC). However, the results of studies on its prognostic value remain controversial. This study aims to evaluate the prognostic significance of the PLR in patients with OSCC. Materials and methods: We conducted a comprehensive search of PubMed, Embase, the Cochrane Library, and Web of Science databases for all studies investigating the association between PLR and prognosis in OSCC, from the inception of each database up to November 2023. The outcome measures included overall survival (OS), disease-free survival (DFS) and disease-specific survival (DSS). To identify potential sources of heterogeneity, sensitivity and subgroup analyses were performed, alongside an assessment of publication bias. The analyses in this study were conducted using RevMan and Stata software. Results: According to the inclusion criteria, 20 articles were included, including 5,714 patients.The meta-analysis revealed that an elevated PLR adversely affects OS (HR = 1.58; 95% CI: 1.29–1.94; p < 0.0001), DFS (HR = 1.71; 95% CI: 1.20–2.42; p < 0.003), and DSS (HR = 2.41; 95% CI: 1.79–3.25; p < 0.00001). The results of the subgroup analysis showed that a preoperative high PLR was associated with reduced OS when the PLR threshold was ≤ 150 (HR = 1.49, P = 0.0003).When the PLR threshold was > 150, Preoperative PLR was not significantly associated with the prediction of overall survival (OS) in OSCC. (P > 0.05). Conclusion: The prognostic significance of PLR in patients with oral cancer is evident in terms of OS, DSS, and DFS. Nonetheless, it is crucial to note that the predictive value of PLR might depend on specific threshold values. [ABSTRACT FROM AUTHOR]

Background: DNA polymerase theta (POLQ) is a translesion synthesis polymerase essential for the repair of double strand breaks by the error-prone TMEJ (Theta Mediated End Joining) pathway. Although POLQ participates in maintaining genome stability, several studies have shown that its overexpression correlates with cancer progression and poor prognosis. Due to the fact that its role as a biomarker in pancreatic cancer remains unexplored, we aimed to study the usefulness of POLQ H-score as a prognostic factor in a pancreatic cancer patient cohort. Methods: We evaluated POLQ gene expression using a web-based tool to deliver gene expression profiling and interactive analyses based on TCGA and GTEx (GEPIA) and we examined the POLQ immunostaining in 152 biliopancreatic cancer surgical specimens using tissue microarrays. Association with survival was evaluated by Kaplan Meier curves and uni-multivariate Cox regression. Results: GEPIA analysis showed statistical differences according to POLQ mRNA levels in Disease Free Survival (DFS) (log rank 0.023, HR 2.8, p=0.029) and Overall Survival (OS) (log rank 0.011, HR 3.1, p=0.016). For immunohistochemistry (IHC) evaluation, POLQ H-score was calculated, and showed statistical differences for OS in Kaplan Meier curves (log rank 0.001) and uni-multivariate analysis (HR 2.27; 95% CI 1.24-4.15, p=0.008). Conclusions: Our results indicate that POLQ is an independent prognostic factor in pancreatic cancer when analyzed by immunostaining, which is in agreement with the results shown by the POLQ gene expression analysis (GEPIA).

BACKGROUND Incorporating brentuximab vedotin into the treatment of advanced-stage classic Hodgkin's lymphoma improves outcomes in adult and pediatric patients. However, brentuximab vedotin increases the toxic effects of treatment in adults, more than half of pediatric patients who receive the drug undergo consolidative radiation, and relapse remains a challenge. Programmed death 1 blockade is effective in Hodgkin's lymphoma, including in preliminary studies involving previously untreated patients. METHODS We conducted a phase 3, multicenter, open-label, randomized trial involving patients at least 12 years of age with stage III or IV newly diagnosed Hodgkin's lymphoma. Patients were randomly assigned to receive brentuximab vedotin with doxorubicin, vinblastine, and dacarbazine (BV+AVD) or nivolumab with doxorubicin, vinblastine, and dacarbazine (N+AVD). Prespecified patients could receive radiation therapy directed to residual metabolically active lesions. The primary end point was progression-free survival, defined as the time from randomization to the first observation of progressive disease or death from any cause. RESULTS Of994 patients who underwent randomization, 970 were included in the intention-totreat population for efficacy analyses. At the second planned interim analysis, with a median follow-up of 12.1 months, the threshold for efficacy was crossed, indicating that N+AVD significantly improved progression-free survival as compared with BV+AVD (hazard ratio for disease progression or death, 0.48; 99% confidence interval [CI], 0.27 to 0.87; two-sided P=0.001). Owing to the short follow-up time, we repeated the analysis with longer follow-up; with a median follow-up of 2.1 years (range, 0 to 4.2 years), the 2-year progression-free survival was 92% (95% CI, 89 to 94) with N+AVD, as compared with 83% (95% CI, 79 to 86) with BV+AVD (hazard ratio for disease progression or death, 0.45; 95% CI, 0.30 to 0.65). Overall, 7 patients received radiation therapy. Immune-related adverse events were infrequent with nivolumab; brentuximab vedotin was associated with more treatment discontinuation. CONCLUSIONS N+AVD resulted in longer progression-free survival than BV+AVD in adolescents and adults with stage III or IV advanced-stage classic Hodgkin's lymphoma and had a better side-effect profile.

Objective: The efficacy of lymph node ratio (LNR) as a prognostic indicator in locally advanced gastric cancer (LAGC) patients underwent radical resection after neoadjuvant immunochemotherapy (NICT) remains to be demonstrated. The objective of the current retrospective study is to investigate the relationship between LNR and survival in patients with LAGC who underwent radical resection after NICT. Methods: A retrospective analysis was performed on 121 cases of LAGC in patients underwent radical resection after NICT between July 2020 and October 2023. The LNR values of the patients were divided into two groups using X-tile software. The first group, designated the low LNR group, comprised patients with LNR values of ≤ 33%. The second group, designated the high LNR group, comprised patients with LNR values of > 33%. The correlation between patient survival rates and a range of clinical and pathological variables was examined. Results: Overall, 121 patients were enrolled: 108 with low-LNR (LNR ≤ 33%) and 13 with high-LNR (LNR > 33%). A better 2-year overall survival (OS) (88.5% vs. 32.6%; p < 0.001) and progression-free survival (PFS) (80.2% vs. 23.5%; p < 0.001) were observed in patients with low LNR. A similar result was also found in those with non-pathological complete response group (non-pCR), where the 2-year OS was 87.2% vs. 32.6% (p < 0.001), and the 2-year PFS was 77.7% vs. 23.5% (p < 0.001). Compared to the pathologic lymph nodes staging (ypN), LNR exhibited similar prognostic capabilities for OS and PFS. Multivariate analysis indicated that LNR was an independent prognostic factor for both OS (HR 6.258, 95% CI 1.798–21.778; p = 0.004) and PFS (HR 3.431, 95% CI 1.341–8.780; p = 0.010), but not ypN. Conclusions: LNR may serve as a viable indicator for prognostication in LAGC patients treated with NICT. [ABSTRACT FROM AUTHOR]

Background: Exploration of novel combination mode of pyrotinib and chemotherapy for heavily pretreated HER2-positive metastatic breast cancer (MBC) and how to balance survival benefits and compliance are still urgent problems in clinical practice. The current single-arm prospective phase II study aimed to evaluate the efficacy and safety of pyrotinib in combination with metronomic oral etoposide in heavily pretreated HER2-positive MBC. Methods: HER2-positive MBC patients previously treated with trastuzumab were enrolled to receive oral pyrotinib 400 mg per day and metronomic oral etoposide 50 mg per day d1-21 every 28 days, until disease progression or unacceptable toxicity. The primary endpoint was progression-free survival (PFS). The secondary endpoints were objective response rate (ORR), disease control rate (DCR), clinical benefit rate (CBR), overall survival (OS), and safety. Results: 22 patients were enrolled with a median of 4 prior treatment regimens for MBC. During the follow-up of 20 evaluable patients, the median PFS was 9.0 months (95% CI, 7.6–10.4 months), and the median OS was 27.0 months (95%CI, 20.9–33.1 months). The ORR was 30% (6/20), the DCR was 80% (16/20), and the CBR was 65% (13/20). The most common grade 3 adverse events (AEs) included nausea (15%), vomiting (15%), diarrhea (5%), anemia (5%), and peripheral neuropathy (5%). No grade 4 or lethal AEs were observed. Conclusion: The combination of pyrotinib with metronomic oral etoposide has achieved promising clinical benefits in heavily pretreated HER2-positive MBC, with acceptable and manageable toxicity.

Background: Pancreatic adenocarcinoma (PAC) is a disease of decimal prognosis, with around 50% of patients presenting with metastatic disease. Previous trials reported a high incidence of early onset pancreatic cancer (EOPAC) in Egypt, presenting about 25% of patients with PAC. The clinic-pathological features and prognosis of EOPAC needs more study. Patients and methods: A retrospective analysis of patients' records at Shefa Al-Orman comprehensive cancer center database. Patients with histo-pathologically confirmed diagnosis of PAC. We categorized patients according to the age at diagnosis into EOPAC (≤ 50 years) and average onset PAC (AOPAC). Data on risk factors, family history, presenting symptoms, clinic-pathological features, treatment, and prognosis were extracted. Patients with histopathologically confirmed diagnosis of pancreatic cancer diagnosed between December 2016-December 2022 were included. Results: The study cohort consisted of 412 patients. EOPAC represented 20.3% of patients, with no significant differences in risk factors and family history compared to AOPAC. Duration of symptoms before diagnosis is longer in EOPAC, with the majority of EOPAC presenting with localized disease (23.8%) and locally advanced tumors (28.5%) compared to AOPAC. AOPAC presented more with metastatic disease (64% vs. 45.2%, p = 0.003). EOPAC are usually submitted to more aggressive treatment including radical surgery, neoadjuvant therapy, and aggressive chemotherapy regimens in metastatic disease. Disease free survival (DFS) of EOPAC was shorter than AOPAC (11 months vs. 17 months, p = 0.889), but overall survival OS was significantly longer in EOPAC (10 months vs. 6 months, p = 0.013). Conclusion: Patients with EOPAC in Egypt represent around 25% of cases. EOPAC tend to have a shorter disease free survival (DFS) in patients presenting with localized disease. The overall survival (OS) is longer in EOPAC compared to AOPAC. Further studies are mandatory to identify the epidemiological and risk factors of EOPAC in Egypt. [ABSTRACT FROM AUTHOR]
