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.

Background: Genetic studies of ovarian cancer (OC) have historically focused on BRCA1/2 mutations, lacking other studies of homologous recombination repair (HRR). Poly (ADP-ribose) polymerase inhibitors (PARPi) exploit synthetic lethality to significantly improve OC treatment outcomes, especially in BRCA1/2 deficiency patients. Objectives: Our study aims to construct a mutation map of HRR genes in OC and identify factors influencing the efficacy of PARPi. Design: A retrospective observational analysis of HRR gene variation data from 695 OC patients from March 2019 to February 2022 was performed. Methods: The HRR gene variation data of 695 OC patients who underwent next-generation sequencing (NGS) in the First Affiliated Hospital of Zhengzhou University were retrospectively collected. Clinical data on the use of PARPi in these patients were also gathered to identify factors that may interfere with the efficacy of PARPi. Results: Out of 127 pathogenic variants in the BRCA1/2 genes, 104 (81.9%) were BRCA1 mutations, and 23 (18.1%) were BRCA2 mutations. Among the 59 variants of uncertain significance (VUS), 20 (33.9%) were BRCA1, while 39 (66.1%) were BRCA2 mutations. In addition to BRCA1/2, HRR gene results showed that 9 (69%) of 13 were HRR pathway pathogenic variants; and 16 (1.7%) of 116 VUS were Food and Drug Administration (FDA)-approved mutated HRR genes. Notably, the treatment regimen significantly influenced the effectiveness of PARPi, especially when using first-line maintenance therapy, leading to enhanced progression-free survival (PFS) compared to alternative protocols. Conclusion: Focusing on HRR gene mutations and supporting clinical research about PARPi in OC patients is crucial for developing precision treatment strategies and enhancing prognosis.

Abstract\nKEY POINTSThe ideal treatment paradigm for bulky diffuse large B-cell lymphoma (DLBCL) remains uncertain. We investigated the impact of tumor bulk in patients treated with systemic therapy alone through Alliance/CALGB 50303. Data from this trial were obtained from the National Cancer Institute’s NCTN/NCORP Data Archive. The study assessed the size of nodal sites and estimated progression-free survival (PFS) using Cox proportional hazards models. Stratified analysis factored in International Prognostic Index (IPI) risk scores. Out of 524 patients, 155 had pretreatment scans. Using a 7.5 cm cutoff, 44% were classified as bulky. Bulk did not significantly impact progression-free survival (PFS), whether measured continuously or at thresholds of >5 or >7.5 cm (p = 0.10–p = 0.99). Stratified analyses by treatment group and IPI risk group were also non-significant. In this secondary analysis, a significant association between bulk and PFS was not identified.The prognosis of upfront tumor bulk in DLBCL remains unclear. In this secondary analysis of a phase III trial comparing DA-EPOCH-R to R-CHOP, a significant association between upfront tumor bulk and PFS was not identified. [ABSTRACT FROM AUTHOR]

Blinatumomab has emerged as a promising component of first-line therapy for acute B-cell precursor lymphoblastic leukemia (BCP-ALL), bolstering treatment efficacy. To mitigate CD19 selection pressure and reduce the incidence of blinatumomab-associated toxicities, pre-treatment chemotherapy is recommended before administering blinatumomab. From September 2022 to December 2023, we conducted a single-arm, multicenter, phase 2 trial (NCT05557110) in newly diagnosed Philadelphia chromosome-negative BCP-ALL (Ph-negative BCP-ALL) patients. Participants received induction treatment with reduced-dose chemotherapy (RDC), comprising idarubicin, vindesine, and dexamethasone over 7 days, followed by 2 weeks of blinatumomab. Those failing to achieve composite complete remission (CRc) received an additional 2 weeks of blinatumomab. The primary endpoint was the CRc rate post initial induction treatment. Of the 35 enrolled patients, 33 (94%) achieved CRc after 2 weeks of blinatumomab, with 30 (86%) achieving measurable residual disease (MRD) negativity. Two patients extended blinatumomab to 4 weeks. With either 2 or 4 weeks of blinatumomab treatment, all patients achieved CR (35/35) and 89% (31/35) were MRD negativity. The median time to CR was 22 days. Immune effector cell-associated neurotoxicity syndrome was limited (14%, all grade 1). Non-hematological adverse events of grade 3 or higher included pneumonia (17%), sepsis (6%), and cytokine release syndrome (9%). With a median follow-up of 11.5 months, estimated 1-year overall survival and 1-year progression-free survival rates were 97.1% and 82.2%, respectively. These findings affirm that RDC followed by blinatumomab is an effective and well-tolerated induction regimen for newly diagnosed Ph-negative BCP-ALL, supporting a shift towards less intensive and more targeted therapeutic approaches.

Background: Patients with gastric cancer (GC) who underwent radical surgery require long-term follow-up (usually 5 years). The purpose of this study was to explore individualized follow-up strategies for patients with GC. Methods: This is a retrospective cohort study that established a clinicopathologic database of patients who underwent gastrectomy from January 2010 to December 2020 at Ningbo No. 2 Hospital. Follow-up was performed until March 2023. The rate of new-onset recurrence of patients with GC was explored annually according to different pTNM stages, defining a recurrence rate of less than 1% as adequate follow-up time. Results: Of the 1606 patients who were eligible, the total number of patients who completed the 5- and 10-year follow-up was 1107 and 586, respectively. A total of 444 cases were diagnosed with recurrence. The recurrence rate for stage IA patients was consistently less than 1% during the follow-up time. The adequate follow-up time (the rate of new-onset recurrence less than 1%) was 5 years for stage IB and IIA patients, and 8 years for stage IIB and IIIA patients, respectively. In contrast, stage IIIB patients were always at risk of recurrence during the follow-up time (>1%). Time to a new recurrence rate for stage IIIC patients was 6 years. Conclusion: Among patients who underwent radical gastrectomy, the rate of new-onset recurrence varied among patients with different pTNM stages. This study suggests that the follow-up of GC can be individualized and refer to pTNM stage. [ABSTRACT FROM AUTHOR]

Background: Potentially curative therapy for locally advanced gastric cancer consists of gastrectomy, usually in combination with perioperative chemotherapy. An oncological resection includes a radical (R0) gastrectomy and modified D2 lymphadenectomy; generally, a total omentectomy is also performed, to ensure the removal of possible microscopic disease. However, the omentum functions as a regulator of regional immune responses to prevent infections and prevents adhesions which could lead to bowel obstructions. Evidence supporting a survival benefit of routine complete omentectomy during gastrectomy is lacking. Methods: OMEGA is a randomized controlled, open, parallel, non-inferiority, multicenter trial. Eligible patients are operable (ASA < 4) and have resectable (≦ cT4aN3bM0) primary gastric cancer. Patients will be 1:1 randomized between (sub)total gastrectomy with omentum preservation distal of the gastroepiploic vessels versus complete omentectomy. For a power of 80%, the target sample size is 654 patients. The primary objective is to investigate whether omentum preservation in gastrectomy for cancer is non-inferior to complete omentectomy in terms of 3-year overall survival. Secondary endpoints include intra- and postoperative outcomes, such as blood loss, operative time, hospital stay, readmission rate, quality of life, disease-free survival, and cost-effectiveness. Discussion: The OMEGA trial investigates if omentum preservation during gastrectomy for gastric cancer is non-inferior to complete omentectomy in terms of 3-year overall survival, with non-inferiority being determined based on results from both the intention-to-treat and the per-protocol analyses. The OMEGA trial will elucidate whether routine complete omentectomy could be omitted, potentially reducing overtreatment. Trial registration: ClinicalTrials.gov NCT05180864.

Preoperative identification of intracranial meningiomas with aggressive behaviour may help in choosing the optimal treatment strategy. Radiomics is emerging as a powerful diagnostic tool with potential applications in patient risk stratification. In this study, we aimed to compare the predictive value of conventional, semantic based and radiomic analyses to determine CNS WHO grade and early tumour relapse in intracranial meningiomas. We performed a single-centre retrospective analysis of intracranial meningiomas operated between 2007 and 2018. Recurrence within 5 years after Simpson Grade I-III resection was considered as early. Preoperative T1 CE MRI sequences were analysed conventionally by two radiologists. Additionally a semantic feature score based on systematic analysis of morphological characteristics was developed and a radiomic analysis were performed. For the radiomic model, tumour volume was extracted manually, 791 radiomic features were extracted. Eight feature selection algorithms and eight machine learning methods were used. Models were analysed using test and training datasets. In total, 226 patients were included. There were 21% CNS WHO grade 2 tumours, no CNS WHO grade 3 tumour, and 25 (11%) tumour recurrences were detected in total. In ROC analysis the best radiomic models demonstrated superior performance for determination of CNS WHO grade (AUC 0.930) and early recurrence (AUC 0.892) in comparison to the semantic feature score (AUC 0.74 and AUC 0.65) and conventional radiological analysis (AUC 0.65 and 0.54). The combination of human classifiers, semantic score and radiomic analysis did not markedly increase the model performance. Radiomic analysis is a promising tool for preoperative identification of aggressive and atypical intracranial meningiomas and could become a useful tool in the future. [ABSTRACT FROM AUTHOR]

Although prostate cancer is a common occurrence among males, the relationship between existing risk prediction models remains unclear. The objective of this hospital-based retrospective study is to investigate the impact of polygenic risk scores (PRSs) on the incidence and prognosis of prostate cancer in the Han Chinese population. A total of 24,778 male participants including 903 patients with prostate cancer at Taichung Veterans General Hospital were enrolled in the study. PRS was calculated using 269 single nucleotide polymorphisms and their corresponding effect sizes from the polygenic score catalog. The association between PRS and the risk prostate cancer was evaluated using Cox proportional hazards regression model. Among the 24,778 participants, 903 were diagnosed with prostate cancer. The risk of prostate cancer was significantly higher in the highest quartile of PRS distribution compared to the lowest (hazard ratio = 4.770, 95% CI = 3.999–5.689, p < 0.0001), with statistical significance across all age groups. Patients in the highest quartile were diagnosed with prostate cancer at a younger age (66.8 ± 8.3 vs. 69.5 ± 8.8, p = 0.002). Subgroup analysis of patients with localized or stage 4 prostate cancer showed no significant differences in biochemical failure or overall survival. This hospital-based cohort study observed that a higher PRS was associated with increased susceptibility to prostate cancer and younger age of diagnosis. However, PRS was not found to be a significant predictor of disease stage and prognosis. These findings suggest that PRS could serve as a useful tool in prostate cancer risk assessment.

This study examined to evaluate the predictive value of a nomogram with Ki-67 in overall and disease-free survival in glioma patients, a total of 76 patients diagnosed with glioma by pathology in Tengzhou Central People's Hospital were enrolled. The baseline data and follow ups were retrospectively collected from medical records. The associations between Ki-67 and survival status were examined using log-rank test, univariate and multivariate Cox proportional hazard regression models. Calibrations were performed to validate the established nomograms. Ki-67 negative group showed of a longer OS survival time and a longer PFS survival time with log-rank test (x2 = 16.101, P < 0.001 and x2 = 16.961, P < 0.001). Age older than 50 years (HR = 2.074, 95% CI 1.097–3.923), abnormal treatment (HR = 2.932, 95% CI 1.343–6.403) and Ki-67 positive (HR = 2.722, 95% CI 1.097–6.755) were the independent predictive factors of death. High grade pathology (HR = 2.453, 95% CI 1.010–5.956) and Ki-67 positive (HR = 2.200, 95% CI 1.043–4.639) were the independent predictive factors of recurrence. The C-index for the nomogram of OS and PFS were 0.745 and 0.723, respectively. The calibration results showed that the nomogram could predict the overall and disease-free 1-year survival of glioma patients. In conclusion, the nomograms with Ki-67 as independent risk factor for OS and PFS could provide clinical consultation in the treatment and follow-up of malignant glioma. [ABSTRACT FROM AUTHOR]

To evaluate the prognostic significance of the maximum standardized uptake value (SUVmax) in nasopharyngeal carcinoma (NPC), establish a gene signature that correlates with SUVmax, and explore the underlying biological behaviors associated with these correlations for the prediction of clinical outcomes. A cohort of 726 patients with NPC was examined to identify correlations between SUVmax and various clinical variables. RNA sequencing was performed to identify genes related to SUVmax, and these genes were used to develop an SUV signature. Additionally, transcriptome enrichment analysis was conducted to investigate the potential biological behaviors underlying the observed correlations. Higher SUVmax was associated with an increased tumor burden and worse prognosis. The SUV signature, which consisted of 10 genes, was positively correlated with SUVmax, and it predicted worse survival outcomes. This signature was highly expressed in malignant epithelial cells and associated with hypoxia and resistance to radiotherapy. Additionally, the signature was negatively correlated with immune function. SUVmax is a valuable prognostic indicator in NPC, with higher values predicting worse outcomes. The SUV signature offers further prognostic insights, linking glucose metabolism to tumor aggressiveness, treatment resistance, and immune function, and it could represent a potential biomarker for NPC.

Background: Colorectal cancer is the third most common cancer and the second leading cause of cancer death. There are limited therapeutic options for the treatment of locally advanced or metastatic colorectal cancers which fail first-line chemotherapy. Phase I/II studies showed that the combined application of the raltitrexed and irinotecan has significant synergistic effect and acceptable toxicity. However, most of these previous studies have relatively small sample size. Methods: This is a prospective open-label, single-arm, multi-center, Phase II trial. Brief inclusion criteria: patients were aged 18 to 75 years with locally advanced or metastatic colorectal cancer after failure of 5-FU and oxaliplatin therapy. Enrolled patients received raltitrexed (3 mg/m2, d1) and irinotecan (180 mg/m2, d1) each 21-day cycle until disease progression or unacceptable toxicity. The primary endpoint was progression-free survival, and the secondary endpoints were disease control rate, objective response rate, overall survival and safety. Results: A total of 108 patients were enrolled between September 2016 and May 2020. The median age was 61 years, ECOG 1 score accounts for 67.6%, the rest were ECOG 0. A total of 502 cycles were completed, with an average of 4.6 cycles and a median of 4 cycles. 108 patients were evaluated, with an objective response rate of 17.6%, and disease control rate of 76.9%. The median follow-up time was 27 months (range:3.1–61.0 m) at data cut-off on March 2023. Median progression-free survival was 4.9 months (95% CI 4.1–5.7) and median overall survival was 13.1 months (95% CI 12.2–15.5). The most common adverse events that were elevated are alanine aminotransferase increased, aspartate aminotransferase increased, fatigue, diarrhoea, neutrocytopenia, thrombocytopenia, hypohemoglobin, and leukocytopenia. Most of the adverse events were Grade I/II, which were relieved after symptomatic treatment, and there were no treatment-related cardiotoxicities and deaths. Conclusions: The combination of raltitrexed and irinotecan as second-line treatment for mCRC could be a reliable option after failure of standard 5-Fu-first-line chemotherapy in locally advanced or metastatic colorectal cancers, especially for patients with 5-FU intolerance (cardiac events or DPD deficiency patients).

AbstractObjectiveMethodsResultsConclusionTalquetamab is the first GPRC5D-targeting bispecific antibody approved for the treatment of triple-class exposed (TCE) relapsed/refractory multiple myeloma (RRMM). This matching-adjusted indirect comparison (MAIC) study was conducted to compare the effectiveness of talquetamab vs selinexor-dexamethasone (sel-dex) and vs belantamab mafodotin (belamaf) in patients with TCE RRMM.An unanchored MAIC was performed using individual patient-level data from patients treated with subcutaneous talquetamab 0.4 mg/kg weekly (QW) and 0.8 mg/kg every other week (Q2W) from MonumenTAL-1 (NCT03399799/NCT04636552) and published summary data for sel-dex from STORM (NCT02336815) and belamaf from DREAMM-2 (NCT0325678). Patients from MonumenTAL-1 who met key eligibility criteria for STORM and DREAMM-2 were included. Outcomes of interest were overall response rate (ORR), complete response or better (≥CR), duration of response (DOR), progression-free survival (PFS), and overall survival (OS).After adjustment for cross-trial differences, patients treated with both dosing schedules of talquetamab showed significantly better ORR, ≥CR, and DOR vs sel-dex and significantly higher ORR and ≥ CR vs belamaf; DOR was relatively similar to belamaf. PFS was significantly improved with talquetamab Q2W and numerically in favor of talquetamab QW vs sel-dex and significantly improved with both dosing schedules of talquetamab vs belamaf. OS was significantly improved with both dosing schedules of talquetamab vs sel-dex and was numerically in favor of both dosing schedules of talquetamab vs belamaf.These analyses show superior effectiveness of both talquetamab dosing schedules vs sel-dex and vs belamaf for most outcomes and highlight talquetamab as an effective treatment option for patients with TCE RRMM.

Background: Angioimmunoblastic T-cell lymphoma (AITL) is known for its unfavorable survival prognosis. Chidamide has shown efficacy in relapsed/ refractory AITL, but its efficacy in newly diagnosed AITL is uncertain Objective: This retrospective research aimed to evaluate the effectiveness and safety of chidamide when used with doxorubicin, cyclophosphamide, prednisone, and vincristine (CHOP) in comparison to CHOP by itself for individuals newly diagnosed with AITL, and to examine the impact of transplantation. Method: This was an analysis that compared outcomes among patients who received chidamide + CHOP on a clinical trial vs. historical controls who received CHOP alone, enrolling a total of sixty-six treatment-naive AITL patients between April 2014 and November 2022. Among them, thirty-three received chidamide in addition to CHOP (chidamide group), while thirty-three received CHOP alone (control group). The clinical characteristics were balanced between the two groups. All patients were scheduled to undergo up to six courses of treatment before transplantation. Results: The chidamide group had a significantly longer median overall survival (OS) compared to the control group, with a median OS that was not reached, as opposed to 20 months in the control group (p = 0.002). In the control group, the median progression-free survival (PFS) was 11 months, while in the chidamide group, it was 22 months (p = 0.080). In the high-risk group (IPI ≥ 3), the chidamide group demonstrated notably superior complete response (CR) and overall response rate (ORR) compared to the control cohort (p = 0.002, p = 0.034). The PFS and OS in the chidamide group were not reached, and there were significant differences compared to the control group (p = 0.007, p = 0.003). The median OS of the transplanted group was longer than the nontransplanted group (p = 0.004). On multivariate analysis, chidamide group reduced the hazards of death in the total cohort. Conclusion: As the study was non-random and retrospective, Chidamide combined with chemotherapy should be tested in randomized trials given its potential to improve prognosis in treatment-naive AITL patients. Furthermore, autologous hematopoietic stem cell transplantation (auto-HSCT) has demonstrated enhanced overall survival in individuals with AITL. [ABSTRACT FROM AUTHOR]

Objective: To assess the effectiveness and tolerability of both PD-1 and PD-L1 inhibitors in advanced cervical cancer (CC), focusing on varying PD-L1 levels. Methods: A comprehensive exploration was carried out on EMBASE, PubMed, Cochrane Library databases as well as Web of Science up to May 25, 2024, for studies involving advanced CC patients receiving PD-1/PD-L1 inhibitors. Inclusion criteria were studies reporting objective response rate (ORR), disease control rate (DCR), median progression-free survival (PFS), as well as median overall survival (OS). Data extraction and quality assessment were performed by two reviewers using the JBI Case Series Critical Appraisal Checklist, followed by a meta-analysis via STATA/MP 16.0. Results: Five eligible studies comprising 223 patients were chosen. ORR and DCR were 42% (95% CI: 17%-66%, P = 0.00) and 70% (95% CI: 22%-117%, P = 0.00), respectively, in the PD-L1 positive patients and were 36% (95% CI: 17%-54%, P = 0.00) and 47% (95% CI: 30%-63%, P = 0.00), respectively, in patients with PD-L1 negativity. For patients exhibiting PD-L1 positivity, median PFS and median OS were 3.98 months (95% CI: 0.80-7.16, P = 0.01) and 11.26 months (95% CI: 3.01-12.58, P = 0.00), respectively. Conclusion: With PD-1/PD-L1 inhibitors, PD-L1 positive CC patients demonstrate superior ORR, DCR, median PFS, and median OS, underscoring PD-L1 as one biomarker for immunotherapy response.

Background: While Heat Shock Protein 60 (HSP60) has been linked to human tumor, its clinic significance specifically in breast carcinoma is unclear. This investigation aims to retrospectively evaluate how HSP60 protein levels relate to survival outcomes among patients diagnosed with breast carcinoma. Methods: Evaluation of 206 patients diagnosed with breast carcinoma and receiving treatment from January 2012 to April 2018, carried out retrospectively. The protein level of HSP60 in breast carcinoma determined by immunohistochemical. Results: The study provided evidence of a distinct upregulation of HSP60 expression in breast carcinoma tumor samples in contrast to adjacent normal tissue samples. Additionally, heightened HSP60 expression was linked to advanced T stage (P = 0.046), N stage (P = 0.034), tumor metastasis (P = 0.016), pathological grading (P = 0.012), and adjuvant therapy utilization (P = 0.004). Moreover, elevated levels of HSP60 proteins exhibited a significant inverse correlation with overall survival (OS) [hazard ratio (HR) 1.598, P = 0.018] and progression-free survival (PFS) (HR 1.600, P = 0.017) among breast carcinoma patients in univariate analyses. The results of multivariate analyses highlighted HSP60 may serve as an independent predictor for both OS and PFS in breast carcinoma patients (HR 1.525, P = 0.034; HR 1.528, P = 0.033, respectively). Conclusion: The involvement of HSP60 in breast carcinoma progression suggests its potential clinical relevance in treatment target validation and prognostic assessment of the disease.

Objectives: The purpose of this study was to assess the association between preoperative neutrophil-to-lymphocyte ratio (NLR) and the survival outcomes of esophageal cancer patients who underwent esophagectomy, the latest and comprehensive systematic review performed. Methods: Related literature retrieved from PubMed, Web of Science, Embase, and Cochrane before January 2024, according to the inclusion criteria. Outcomes measured were overall survival (OS), disease-free survival (DFS), relapse-free survival (RFS), and cancer-specific survival (CSS). Results: Eighteen studies with 6,119 esophageal cancer patients were retained for analysis. Meta-analysis demonstrated that OS (HR: 1.47; 95% CI: 1.29, 1.67; P < 0.00001), DFS (HR: 1.62; 95% CI: 1.29, 2.05; P < 0.0001), and CSS (HR: 1.62; 95% CI: 1.29, 2.05; P < 0.0001) were significantly shorter in the high NLR group compared with the low NLR group. In addition, meta-analysis revealed a similar RFS (HR: 1.47; 95% CI: 0.92, 2.35; P = 0.10) among the two groups. Subgroup analysis of OS and DFS based on mean/median age, NLR cutoff, and region found that all subgroups remained significant difference between two groups. Conclusion: Among esophageal cancer patients who underwent esophagectomy, preoperative NLR can be used as prognostic factor independently. High-preoperative NLR is associated with poor prognosis. More large-scale, multicenter prospective clinical studies are needed to further validate the relationship between preoperative NLR and prognosis of esophageal cancer. [ABSTRACT FROM AUTHOR]

Introduction: The human leukocyte antigen (HLA) evolutionary divergence (HED) reflects immunopeptidome diversity and has been shown to predict the response of tumors to immunotherapy. Its impact on allogeneic hematopoietic stem cell transplantation (HSCT) is controversial in different studies. Methods: In this study, we retrospectively analyzed the clinical impact of class I and II HED in 225 acute lymphoblastic leukemia patients undergoing HSCT from related haploidentical donors. The HED for recipient, donor, and donor-recipient pair was calculated based on Grantham distance, which accounts for variations in the composition, polarity, and volume of each amino acid within the peptidebinding groove of two HLA alleles. The median value of HED scores was used as a cut-off to stratify patients with high or low HED. Results: The class I HED for recipient (R_HEDclass I) showed the strongest association with cumulative incidence of relapse (12.2 vs. 25.0%, P = 0.00814) but not with acute graft-versus-host disease. The patients with high class II HED for donor-recipient (D/R_HEDclass II) showed a significantly higher cumulative incidence of severe aGVHD than those with low D/R_HEDclass II (24.0% vs. 6.1%, P = 0.0027). Multivariate analysis indicated that a high D/R_HEDclass II was an independent risk factor for the development of severe a GVHD (P = 0.007), and a high R_HEDclass I had a more than two-fold reduced risk of relapse (P = 0.028). However, there was no discernible difference in overall survival (OS) or disease free survival (DFS) for patients with high or low HED, which was inconsistent with the previous investigation. Discussion: While the observation are limited by the presented single center retrospective cohort, the results show that HED has poor prognostic value in OS or DFS, as well as the associations with relapse and aGVHD. In haploidentical setting, class II HED for donor-recipient pair (D/R_HEDclass II) is an independent and novel risk factor for finding the best haploidentical donor, which could potentially influence clinical practice if verified in larger cohorts.

Background Early studies showed promise of combined anti-epidermal growth factor receptor (EGFR) plus anti–vascular endothelial growth factor (VEGF) antibodies for advanced colorectal cancer (CRC), yet this was later rejected as toxic and ineffective in studies not selected for RAS status. We studied advanced KRAS wild-type CRC, as second-line treatment, using irinotecan-cetuximab with or without the anti-VEGF receptor antibody ramucirumab. Methods Patients with 1 prior regimen including fluoropyrimidine, oxaliplatin, and bevacizumab, with KRAS wild-type tumors were stratified by Eastern Cooperative Oncology Group Performance Score, time since last chemotherapy, and progression on oxaliplatin to irinotecan-cetuximab (IC) (180 mg/m2 and 500 mg/m2 every 2 weeks) vs modified ICR (irinotecan-cetuximab with ramucirumab 150 mg/m2 and 400 mg/m2 plus 6 mg/kg, respectively). A total of 102 patients were compared for progression-free survival (PFS) as primary endpoint (85% power for 70% improvement in median PFS from 4.5 to 7.65 months). Results Of the 102 enrolled, 44 treated with irinotecan-cetuximab and 45 with modified ramucirumab were evaluable. Median PFS was 6.0 months vs 9.2 months, respectively (hazard ratio = 0.75, P = .07; statistically significant by study design for P  < .128). Response rate was 23% vs 36% (P = .27), and disease-control rate was 52% vs 73% (P  = .05). Grade 3 or higher toxicity was equivalent. Overall survival was not significantly different at approximately 19 months. Conclusion Previous phase 3 trials without RAS genotyping rejected combining anti-epidermal growth factor receptor and anti-VEGF drugs. In this randomized multicenter phase 2 study for KRAS wild-type CRC (all previously bevacizumab treated), the addition of ramucirumab to irinotecan and cetuximab improved PFS and disease control rate, showing the combination is feasible and effective. Further, phase 3 trials with appropriate patient-selection are required. (NCT01079780) [ABSTRACT FROM AUTHOR]

Background Camonsertib is a selective oral inhibitor of ataxia telangiectasia and Rad3-related (ATR) kinase with demonstrated efficacy in tumors with DNA damage response gene deficiencies. On-target anemia is the main drug-related toxicity typically manifesting after the period of dose-limiting toxicity evaluation. Thus, dose and schedule optimization requires extended follow-up to assess prolonged treatment effects. Methods Long-term safety, tolerability, and antitumor efficacy of 3 camonsertib monotherapy dosing regimens were assessed in the TRESR study dose-optimization phase: 160 mg once daily (QD) 3 days on, 4 days off (160 3/4; the preliminary recommended Phase II dose [RP2D]) and two step-down groups of 120 mg QD 3/4 (120 3/4) and 160 mg QD 3/4, 2 weeks on, 1 week off (160 3/4, 2/1w). Safety endpoints included incidence of treatment-related adverse events (TRAEs), dose modifications, and transfusions. Efficacy endpoints included overall response rate, clinical benefit rate, progression-free survival, and circulating tumor DNA (ctDNA)-based molecular response rate. Results The analysis included 119 patients: 160 3/4 (n = 67), 120 3/4 (n = 25), and 160 3/4, 2/1w (n = 27) treated up to 117.1 weeks as of the data cutoff. The risk of developing grade 3 anemia was significantly lower in the 160 3/4, 2/1w group compared with the preliminary RP2D group (hazard ratio = 0.23, 2-sided P  = .02), translating to reduced transfusion and dose reduction requirements. The intermittent weekly schedule did not compromise antitumor activity. Conclusion The 160 3/4, 2/1w dose was established as an optimized regimen for future camonsertib monotherapy studies offering a substantial reduction in the incidence of anemia without any compromise to efficacy.

Introduction: Lymphoma, encompassing common non-Hodgkin lymphoma (NHL) and less common Hodgkin lymphoma (HL), represents significant hematological malignancies. Advancements in treatment modalities have reshaped survival rates, particularly in NHL. This complexity results in varying outcomes, some requiring extended observation periods and multiple chemotherapy treatments. The primary objective was to explore and compare the overall survival (OS) of HL and NHL at 1, 3, and 5-year follow-ups among adult lymphoma patients in Qatar during January 2013–December 2017. Further objectives encompass comparing the most prevalent histological types, clinical and epidemiological traits of HL and NHL, as well as secondary aims of assessing clinical features, treatment, response, disease-free survival, and OS. Methods: A retrospective, descriptive study of consecutive cases was conducted at Qatar's NCCCR between 2013 and 2017. Inclusion criteria involved patients ≥18 years old, of any gender and clinical stage at diagnosis, who received chemotherapy and had known outcomes. Descriptive statistics were applied, and survival analysis utilized Kaplan-Meier curves. STATA version 13.0 facilitated data analysis. Results: Between 2013 and 2017, 414 individuals in Qatar were diagnosed with lymphoma. The median age at diagnosis was 49 years (IQR 36–95 years; p < 0.001) across all patients. Males exhibited a higher likelihood of developing HL and NHL, comprising 74% and 70% of cases, respectively, though this difference was statistically insignificant (p = 0.45). Among NHL-B subtypes, mature B-cell neoplasms (60%) predominated, while lymphocyte-rich subtype (49%) was prominent in HL cases. With a median follow-up of 17.3 months, OS rates at 1, 3, and 5 years were 99%, 82%, and 64%, respectively for all lymphoma patients. Subtype stratification revealed trends in 3-year follow-up OS (94 vs. 82%) for HL and NHL, with 5-year OS of 67% and 60%, respectively. HL demonstrated higher OS throughout the study period compared to NHL (p < 0.001), though median OS remained unreached. Conclusions: Diffuse large B-cell lymphoma emerged as the most prevalent subtype among lymphomas in Qatar. Generally, HL exhibited superior survival rates, at 67% compared to 60% for NHL. Minor deflation in survival rates, particularly for HL, might be attributed to Qatar's immigration patterns. [ABSTRACT FROM AUTHOR]

Introduction: Few studies have investigated the prognostic factors for non-adenocarcinoma of the lung. We retrospectively evaluated the prognostic factors on the basis of histological type of non-adenocarcinoma of the lung treated by pulmonary resection. Methods: We enrolled 266 patients with non-adenocarcinoma of the lung in this retrospective study: 196 with squamous cell carcinoma (SCC) and 70 with non-SCC. Results: Relapse-free survival (RFS) did not differ significantly between SCC and non-SCC patients (p = 0.33). For SCC patients, RFS differed significantly between patients who underwent wedge resection and non-wedge resection (p < 0.01) and between patients with Clavien-Dindo grade ≥3a and 0–2 postoperative complications (p < 0.01). For non-SCC patients, RFS rates were significantly different in the groups divided at neutrophil-to-lymphocyte ratio = 2.40 (p = 0.02), maximum standardized uptake value (SUVmax) = 8.39 (p < 0.01), between patients with pathological stage (pStage) 0–I and with pStage more than II (p < 0.01). For SCC patients, male sex (p = 0.04), wedge resection (p = 0.01), and Clavien-Dindo grade ≥3a (p = 0.02) were significant factors for RFS in multivariate analysis. For non-SCC patients, neutrophil-to-lymphocyte ratio >2.40 (p < 0.01), SUVmax >8.39 (p = 0.01), and pStage ≥II (p = 0.03) were significant factors for RFS in multivariate analysis. Conclusion: RFS did not differ significantly differently between SCC and non-SCC patients. It is necessary to perform more than segmentectomy and to avoid severe postoperative complications for SCC patients. SUVmax might be an adaptation criterion of adjuvant chemotherapy for patients with non-adenocarcinoma and non-SCC of the lung. [ABSTRACT FROM AUTHOR]

Purpose: Somatostatin receptor (SSTR) imaging features are predictive of treatment outcome for neuroendocrine tumor (NET) patients receiving peptide receptor radionuclide therapy (PRRT). However, comprehensive (all metastatic lesions), longitudinal (temporal variation), and lesion-level measured features have never been explored. Such features allow for capturing the heterogeneity in disease response to treatment. Furthermore, models combining these features are lacking. In this work we evaluated the predictive power of comprehensive, longitudinal, lesion-level 68GA-SSTR-PET features combined with a multivariate linear regression (MLR) model. Methods: This retrospective study enrolled NET patients treated with [177Lu]Lu-DOTA-TATE and imaged with [68Ga]Ga-DOTA-TATE at baseline and post-therapy. All lesions were segmented, anatomically labeled, and longitudinally matched. Lesion-level uptake and variation in uptake were measured. Patient-level features were engineered and selected for modeling of progression-free survival (PFS). The model was validated via concordance index, patient classification (ROC analysis), and survival analysis (Kaplan-Meier and Cox proportional hazards). The MLR was benchmarked against single feature predictions. Results: Thirty-six NET patients were enrolled and stratified into poor and good responders (PFS ≥ 25 months). Four patient-level features were selected, the MLR concordance index was 0.826, and the AUC was 0.88 (0.85 specificity, 0.81 sensitivity). Survival analysis led to significant patient stratification (p<.001) and hazard ratio (3⨯10-5). Lastly, in a benchmark study, the MLR modeling approach outperformed all the single feature predictors. Conclusion: Comprehensive, lesion-level, longitudinal 68GA-SSTR-PET analysis, combined with MLR modeling, leads to excellent predictions of PRRT outcome in NET patients, outperforming non-comprehensive, patient-level, and single time-point feature predictions.

Purpose: To evaluate the reliability of the Deauville score (DS) in therapy response assessment and to define the prognostic value of the metabolic response of end of induction (EOI) [18F]FDG PET (PET) in follicular lymphoma patients. Methods: Adult patients with untreated grade 1–3a FL/ stage II‐IV enrolled in the multicentre, prospective, phase III FOLL12 trial (NCT02063685) were randomized to receive standard immunochemotherapy followed by rituximab maintenance (standard arm) versus standard immunochemotherapy followed by response-adapted post‐induction management (experimental arm). Baseline and EOI PET were mandatory for the study. All PET scans were centralized on the WIDEN® platform and classified according to DS in a blind independent central review. DS1–3 was considered negative (CMR), whereas DS4‐5 was considered positive (not CMR). The primary endpoint was PFS. The main secondary endpoint was overall survival (OS). Results: Overall, 807 follicular lymphoma patients—52% women, 89% stage III-IV disease, 40% with a high-risk FLIPI-2 score (3–5)—were enrolled in the study; 729 (90.4%) baseline and EOI PET were available for the analysis. EOI PET was positive (DS4–5) in 88/729 (12.1%) cases. Overall inter-reviewer agreement on PET pos/neg result was 0.92, while agreement on positive and negative cases was 0.77 and 0.94, respectively. The median follow-up was 69 months; 247 events were registered in the 5-yr follow-up, with a 5-yr PFS of 67% (95%CI: 63%–70%). The 5-yr PFS rate for PET neg (DS1–3) and PET pos (DS4–5) patients was 71% (95%CI: 67%–75%) and 36% (95%CI: 25%–46%), respectively, with HR 3.49 (95%CI: 2.57–4.72). Five-year PFS was worse as DS increased, with 74% (70%–78%), 58% (48%–67%; HR 1.71; p = 0.001)] and 36% (25%–46%; HR 3.88; p < 0.001) in DS1–2, DS3 and DS4–5, respectively. EOI PET maintained its prognostic value in both the standard and experimental arms. In the whole population, 5-yr OS was 94% (95%CI: 92%–96%), with 96% (95%CI: 94–97) and 82% (95%CI: 72%–89%) in EOI PET negative (DS1–3) and positive (DS4–5), respectively (HR 4.48; p < 0.001). When DS was associated with FLIPI-2, patients with DS3 or DS1–2 with high FLIPI-2 (3–5) experienced worse OS than patients with DS1–2 and low FLIPI-2 (1–2) (p = 0.003). Conclusion: This study shows that DS is a reliable prognostic tool to evaluate EOI PET in follicular lymphoma patients, with prognostic value maintained both in the standard and experimental arms, making metabolic imaging a robust tool to assess response in FL. Moreover, although preliminary, this study provides further information on DS3 patients, who are considered as CMR but show a less favourable PFS than DS1–2 patients. [ABSTRACT FROM AUTHOR]

Purpose: Gastroenteropancreatic -neuroendocrine tumours (GEP-NETs) are commonly treated with surgical resection or long-term therapies for tumour growth control. Lutetium [177Lu]-DOTA-TATE was approved for the treatment of GEP-NETs after the phase III NETTER 1trial demonstrated improved progression free survival, objective response rates and health-related quality of life (HRQoL) compared to high-dose somatostatin analogues. No real-world data exist on prescribing habits and clinically significant endpoints for [177Lu]Lu-DOTA-TATE treatment in Italy. REAL-LU is a multicentre, long-term observational study in patients with unresectable/metastatic GEP-NETs progressing on standard therapies in Italian clinical practice. A pre-specified interim analysis was performed at the end of the enrolment period, data from which are described herein. Methods: Overall duration of REAL-LU will be approximately 48 months, with 12- and 36-month recruitment and follow-up periods, respectively. The primary objective is to evaluate [177Lu]Lu-DOTA-TATE effectiveness in terms of progression-free survival. Secondary objectives include safety, impact on HRQoL, and identification of prognostic factors. This pre-specified interim analysis describes patient profiles, at the end of enrollment, of those prescribed [177Lu]Lu-DOTA-TATE for GEP-NETs in Italy. Results: Among 161 evaluable patients, mean age was 64.7 ± 10.3 years at study entry, 83.8% presented with no clinical signs of disease at physical examination, and most had minor disease symptoms. All patients had metastatic disease, most commonly in the liver (83.9%) with a median of two metastatic sites. In 90.7% of patients, the disease was stage IV, and 68.3% had ≥ 1 target lesion. [177Lu]Lu-DOTA-TATE was prescribed mainly as second-line therapy (61.6%) and following surgery (58.4%). HRQoL assessments revealed high levels of functioning and low levels of symptoms at baseline; 50.0% of patients were symptom-free at study entry. Conclusion: The characteristics of patients who received [177Lu]Lu-DOTA-TATE in Italy are similar to those of the GEP-NET population of NETTER 1 with trial but with a higher proportion of patients with a grade 2 (71%). With regard to the tumor grade profile, our study cohort appears to be closer to that of NETTER-2 study population which included patients with G2 or G3 advanced GEP-NETs (i.e. Ki-67 ≥ 10% and ≤ 55%). Further analysis of effectiveness and safety can be anticipated as REAL-LU data mature.

Background: Recent advancements in advanced non‐small‐cell lung cancer (NSCLC) treatment have significantly improved primary therapy outcomes owing to the emergence of various molecular targeted therapies and immune checkpoint inhibitors (ICIs). However, for Kirsten rat sarcoma viral antigen (KRAS) mutations, molecular targeted drugs, such as sotorasib, are not applicable as first‐line treatments, and the optimal primary treatment remains unclear. Therefore, we aimed to investigate the efficacy of ICI combination therapy as first‐line treatment for KRAS‐mutant NSCLC. Methods: We conducted a systematic search for phase 3 randomized controlled trials (RCTs) that presented data on KRAS mutation status in advanced NSCLC. The primary endpoints were progression‐free survival (PFS) and overall survival (OS). A random‐effects network meta‐analysis was conducted to perform direct and indirect comparisons among treatment groups. Results: Six RCTs were eligible for inclusion. In the network meta‐analysis for KRAS‐mutant NSCLC, Chemo + bevacizumab (Bev) + ICI was associated with improved PFS (hazard ratio [HR] 0.38, 95% confidence interval [CI] 0.22–0.64), followed by Chemo + ICI + ICI (HR 0.66, 95% CI 0.47–0.93) and Chemo + ICI (HR 0.67, 95% CI 0.49–0.91). The most beneficial effect on OS was observed with Chemo + Bev + ICI (HR 0.50, 95% CI 0.34–0.73), followed by Chemo + ICI + ICI (HR 0.64, 95% CI 0.48–0.87) and Chemo + ICI (HR 0.72, 95% CI 0.56–0.92). Regarding OS in wild‐type KRAS, ICI + ICI (HR 0.73, 95% CI 0.50–1.07) produced the most favorable effects, followed by Chemo + ICI (HR 0.79, 95% CI 0.63–0.99). Conclusion: The efficacy of Chemo + Bev + ICI is potentially high for improving PFS and OS in KRAS‐mutant NSCLC. In advanced NSCLC, the presence or absence of KRAS mutations may need to be considered when administering first‐line treatment. [ABSTRACT FROM AUTHOR]

Background: Homologous recombination deficiency (HRD) is a biomarker that predicts response to ovarian cancer treatment with poly (ADP‐ribose) polymerase (PARP) inhibitors or breast cancer treatment with first‐line platinum‐based chemotherapy. However, there are few studies on the prognosis of lung cancer patients treated with immune checkpoint inhibitor (ICI) therapy using HRD as a biomarker. Methods: We studied the relationship between HRD status and the effectiveness of first‐line ICI‐based therapy in EGFR/ALK wild‐type metastatic non‐small cell lung cancer patients (NSCLC) patients. Results: This study included 22 treatment naïve NSCLC patients. The HRD score ranged from −26.37 to 92.34, with an average of 24.57. Based on analysis of the progression‐free survival (PFS) data from the included NSCLC patients, threshold traversal was carried out. HRD (+) was defined as an HRD score of 31 or higher. Kaplan–Meier PFS survival analysis showed prolonged median PFS (mPFS) in NSCLC patients with HRD (+) versus HRD (−) (N/A vs. 7.0 ms, log‐rank p = 0.029; HR 0.20, 95% CI: 0.04–0.96, likelihood‐ratio p = 0.03). In patients with PD‐L1 TPS ≥50% and HRD score ≥31 (co‐status high), the mPFS was temporarily not reached during the follow‐up period. In patients with PD‐L1 TPS <1% and HRD score <31, the mPFS was 3 ms. Cox regression analysis showed that the hazard ratio of the co‐status was 0.14 (95% CI: 0.04–0.54), which was a good prognostic factor, and the prognostic effect of co‐status was better than that of HRD score alone. Conclusion: The HRD status can be identified as an independent significance in NSCLC patients treated with first‐line ICI‐based therapy. [ABSTRACT FROM AUTHOR]

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

KIF2C/MCAK (KIF2C) is the most well-characterized member of the kinesin-13 family, which is critical in the regulation of microtubule (MT) dynamics during mitosis, as well as interphase. This systematic review briefly describes the important structural elements of KIF2C, its regulation by multiple molecular mechanisms, and its broad cellular functions. Furthermore, it systematically summarizes its oncogenic potential in malignant progression and performs a meta-analysis of its prognostic value in cancer patients. KIF2C was shown to be involved in multiple crucial cellular processes including cell migration and invasion, DNA repair, senescence induction and immune modulation, which are all known to be critical during the development of malignant tumors. Indeed, an increasing number of publications indicate that KIF2C is aberrantly expressed in multiple cancer entities. Consequently, we have highlighted its involvement in at least five hallmarks of cancer, namely: genome instability, resisting cell death, activating invasion and metastasis, avoiding immune destruction and cellular senescence. This was followed by a systematic search of KIF2C/MCAK's expression in various malignant tumor entities and its correlation with clinicopathologic features. Available data were pooled into multiple weighted meta-analyses for the correlation between KIF2Chigh protein or gene expression and the overall survival in breast cancer, non-small cell lung cancer and hepatocellular carcinoma patients. Furthermore, high expression of KIF2C was correlated to disease-free survival of hepatocellular carcinoma. All meta-analyses showed poor prognosis for cancer patients with KIF2Chigh expression, associated with a decreased overall survival and reduced disease-free survival, indicating KIF2C's oncogenic potential in malignant progression and as a prognostic marker. This work delineated the promising research perspective of KIF2C with modern in vivo and in vitro technologies to further decipher the function of KIF2C in malignant tumor development and progression. This might help to establish KIF2C as a biomarker for the diagnosis or evaluation of at least three cancer entities. [ABSTRACT FROM AUTHOR]

Purpose: The aim of this study was to quantitatively compare the efficacy and safety of CDK4/6 inhibitors and PI3K/AKT/mTOR inhibitors for ER+/HER2− metastatic breast cancer. Methods: A parametric survival function was used to analyze the time course of overall survival (OS) and progression-free survival (PFS). The objective response rate (ORR) and the incidence of any grade and grade 3–4 adverse events were summarized using the random-effects model of a single-arm meta-analysis. Results: This study included 44 arms from 48 publications, with a total sample size of 7881 patients. Our study revealed that CDK4/6 inhibitors had a median OS of 40.7 months, a median PFS of 14.8 months, and an ORR of 40%, whereas PI3K/AKT/mTOR inhibitors had a median OS of 29.8 months, a median PFS of 8.3 months, and an ORR of 20%. Additionally, this study also found that the proportion of patients with visceral metastases and specific endocrine therapy used in combination significantly impact OS and PFS. In terms of adverse events, CDK4/6 inhibitors exhibited a relatively high incidence of hematological adverse events. Conclusion: Our study provides solid quantitative evidence for the first-line recommendation of CDK4/6 inhibitors combined with endocrine therapy for ER+/HER2− metastatic breast cancer in clinical guidelines.

Background: Central nervous system (CNS) tumors are among the most common malignancies in various age ranges. Low-grade glioma (LGG) can account for nearly 30% of pediatric CNS malignancies. Progression or recurrence after the first-line treatments is common among these patients. Therefore, more treatments are required. Bevacizumab as an anti-VEGF antibody has come into the spotlight recently and is especially used in relapse or recurrence settings. This review aims to study the safety and efficacy of bevacizumab for patients with recurrent LGG. Methods: This study was conducted according to The Preferred Reporting Items for Systematic Reviews and Meta-Analyses. PubMed, Scopus, Web of Science, and Embase were comprehensively searched using the relevant key terms until 24th August 2023 to retrieve the studies that investigated clinical outcomes of bevacizumab in patients with recurrent LGG. All statistical analysis was performed by STATA v.17. Results: A total of 1306 papers were gathered, out of which 13 were incorporated in the meta-analysis. The pooled incidence rate of treatment according to the RANO scale was 70% (95% CI = 43–98%) for objective response rate, 26% (95% CI = 58–96%) for partial response, 21% (95% CI = 15–28%) for minor response, 14% (95% CI = 3–24%) for complete response, 48% (95% CI = 37–59%) for stable disease, and 8% (95% CI = 4–11%) for progressive disease. Furthermore, according to progressive survival after treatment, it was 4% (95% CI = −1 to 9%) for 6-month PFS, 41% (95% CI = 32–50%) for 2-year PFS, and 29% (95% CI = 22–35%) for 3-year PFS. Conclusion: According to the RANO scale and PFS, clinicians should be aware that Bevacizumab could be a favorable alternative therapy for recurrent LGG. Furthermore, bevacizumab exhibits minimal toxicity and high tolerability in recurrent LGG. [ABSTRACT FROM AUTHOR]

Uterine corpus endometrial cancer (UCEC) is a third most common malignancy in women with a poor prognosis in advanced stages. In this study, we performed an integrated comparative analysis of exome and transcriptome data from The Cancer Genome Atlas (TCGA) of Lung Adenocarcinoma (LUAD), and UCEC patients. Our multi-omics analysis shows that the UCEC patients carrying mutations in the KEAP1-NFE2L2-CUL3 genes were associated with better progression-free survival (PFS), whereas the KEAP1-NFE2L2-CUL3 mutation in LUAD showed poor outcomes. Functional annotations and correlative expression studies show that genes, particularly GCLC and GCLM related to glutathione synthesis are expressed at lower levels in the KEAP1-NFE2L2-CUL3 mutant UCEC compared to LUAD. This events result in glutathione deficiency and it may compromise to combat intracellular reactive oxygen species (ROS). However, the expression of genes involved in the glutathione recycling process was not affected. On the other hand, cellular import of cystine is high due to increased SLC7A11 expression in UCEC. Because glutathione synthesis is impaired, the unconverted cysteine accumulates in cells, leading to di-sulfite stress. Apart from NRF2, ARID1A is one of the positive regulators of SLC7A11. In support, UCEC patients with co-occurrence of KEAP1-NFE2L2-CUL3 and ARID1A mutation shows significantly decreased PFS with decline of SLC7A11 expression as compared to patients carrying only KEAP1-NFE2L2-CUL3 mutation. Thus, we hypothesize that the KEAP1-NFE2L2-CUL3 mutation in UCEC leads to uncontrollable ROS with di-sulfite stress, reflecting a favorable clinical outcome. [Display omitted] • KEAP1-NFE2L2-CUL3 (KNC) mutations leads favorable clinical outcome in uterine corpus endometrial carcinoma (UCEC). • Expression of genes involved in glutathione synthesis differs in UCEC compared to lung adenocarcinoma (LUAD). • Co-occurrence of KNC and ARID1A mutation shows declined PFS as compared to the UCEC patients carrying only KNC mutation. • KNC mutations in UCEC leads to uncontrollable ROS with di-sulfite stress, reflecting a healthier PFS in comparison with LUAD.

This study aimed to examine the immunohistochemical expression of epithelial–mesenchymal transition biomarkers: P4HA2 and SLUG in colorectal carcinoma (CRC) specimens, then to assess their relation to clinicopathological features including KRAS mutations and patients' survival, and finally to study the correlation between them in CRC. The result of this study showed that SLUG and P4HA2 were significantly higher in association with adverse prognostic factors: presence of lympho-vascular invasion, perineural invasion, higher tumor budding, tumor stage, presence of lymph node metastasis, and presence of distant metastasis. CRC specimens with KRAS mutation were associated with significant higher SLUG and P4HA2 expression. High expression of both SLUG and P4HA2 was significantly unfavorable prognostic indicator as regards overall survival (OS) and disease-free survival (DFS). In KRAS mutated cases, high P4HA2 expression was the only significant poor prognostic indicator as regarding DFS. In conclusions, our data highlight that both SLUG and P4HA2 expression may serve as potentially important poor prognostic biomarkers in CRC and targeting these molecules may be providing a novel therapeutic strategy. In KRAS mutation group, high P4HA2 expression is the only independent prognostic factor for tumor recurrence, so it can be suggested to be a novel target for therapy. [ABSTRACT FROM AUTHOR]

Background: Adjuvant chemotherapy following curative surgery for locally advanced gastric cancer (AGC) significantly improves long-term patient prognosis. However, delayed chemotherapy (DC), in which patients are unable to receive timely treatment, is a common phenomenon in clinical practice for various reasons. This study aimed to investigate the impact of DC on the prognosis of patients with stage II–III locally AGC and explore the associated risk factors. Methods: Data from four prospective studies were included in the pooled analysis. The planned chemotherapy (PC) group was defined as the time interval between surgery and the first chemotherapy ≤ 49 d, while the DC group was defined as the time interval between surgery and chemotherapy > 49 d. The prognosis, recurrence, and risk factors were compared, and a nomogram for predicting DC was established. Results: In total, 596 patients were included, of whom 531 (89.1%) had PC and 65 (10.9%) had DC. Survival analysis revealed that the 5-year overall survival (OS) and disease-free survival (DFS) were significantly lower in the DC group than those in the PC group (log-rank P < 0.001). Cox univariable and multivariable analyses showed that DC was an independent risk factor for OS and DFS in stage II–III patients (P < 0.05). Based on the significant factors for DC, a prediction model was established that had a good fit, high accuracy (AUC = 0.780), and clinical applicability in both the training and validation sets. Conclusion: Delayed chemotherapy after gastrectomy is associated with poor long-term prognosis in patients with locally advanced stage II–III GC disease. But standardized, full-cycle adjuvant chemotherapy after surgery may play a remedial role, and can to a certain extent compensate the poor effects caused by delayed chemotherapy.

Background: In the FIGHT study (NCT03694522) bemarituzumab, a humanized monoclonal antibody selective for fibroblast growth factor receptor 2b (FGFR2b), plus mFOLFOX6 showed clinically meaningful efficacy in patients with FGFR2b-positive (2+/3+ membranous staining by immunohistochemistry) locally advanced unresectable/metastatic gastric/gastroesophageal cancer (G/GEJC). A meaningful proportion of patients in FIGHT were enrolled in East Asia, reflecting global epidemiology of G/GEJC. Methods: This subgroup analysis of the global, phase 2, double-blind FIGHT study included all patients enrolled in East Asian sites. Patients were randomized 1:1 to bemarituzumab-mFOLFOX6 (15 mg/kg and one 7.5 mg/kg dose on cycle 1, day 8) or matching placebo-mFOLFOX6. The primary endpoint was investigator-assessed progression-free survival (PFS). Secondary endpoints included overall survival (OS), objective response rate, and safety. Efficacy was evaluated after a minimum follow-up of 24 months. Results: The East Asian subgroup comprised 89 patients (57% of overall study population); 45 were randomized to bemarituzumab-mFOLFOX6 and 44 to placebo-mFOLFOX6. Median PFS (95% confidence interval [CI]) was 12.9 months (8.8–17.9) with bemarituzumab-mFOLFOX6 and 8.2 months (5.6–10.3) with placebo-mFOLFOX6 (HR 0.50, 95% CI 0.29–0.87); median OS (95% CI) was 24.7 months (13.8–33.1) vs 12.9 months (9.3–21.4), respectively (HR 0.56, 95% CI 0.32–0.96). Treatment benefit was more pronounced in patients with FGFR2b-positive G/GEJC in ≥ 10% of tumor cells. No new safety signals were reported. Conclusion: In East Asian patients with FGFR2b-positive advanced/metastatic G/GEJC enrolled in the global FIGHT study, bemarituzumab-mFOLFOX6 showed clinically meaningful outcomes over placebo-mFOLFOX6.

This article examines the use of a 1-hour postload plasma glucose (PG) cut-off of 11.6 mmol/L to diagnose type 2 diabetes in pregnant women with gestational diabetes. The study found that women with higher 1-hour PG values were more likely to have worse postpartum and cardiometabolic profiles. The prevalence of postpartum diabetes was significantly higher in women with elevated 1-hour PG values. This suggests that using the 1-hour PG cut-off may help identify women at higher risk for postpartum diabetes and cardiometabolic complications. The study focused on South Asian women with gestational diabetes, and further research is needed to validate these findings in larger and more diverse populations. The article also provides information on the authorship and funding of the research project. [Extracted from the article]

Objective: This study compared the efficacy and safety of the transarterial chemoembolization with CalliSpheres® drug-eluting beads loading with doxorubicin (DEB-TACE) versus conventional lipiodol (cTACE) in patients with unresectable hepatocellular carcinoma (HCC). Methods: A randomized controlled trial (RCT) was conducted with 144 patients, who were randomly assigned to receive either DEB-TACE with doxorubicin-loaded CalliSpheres® microspheres or cTACE with doxorubicin-lipiodol emulsion. Patients were followed up for 12 months, with assessments at 3 and 12 months posttreatment. The primary endpoint was the clinical response rate (CR), and the secondary endpoints were the overall survival (OS), the progression-free survival (PFS), and the safety profile of the two treatments. Results: The results showed that DEB-TACE was superior to cTACE in terms of CR (50.0% vs 30.6% at 3 months, p = 0.03; 43.1% vs 25.0% at 12 months, p = 0.04), OS (18.2 months vs 14.6 months, p < 0.05), and PFS (7.4 months vs 4.8 months, p < 0.05), and that the safety profile of the two treatments was similar (p > 0.05 for all comparisons). However, the efficacy of DEB-TACE and cTACE varied according to the tumor morphology. DEB-TACE showed better CR rates in patients with nodular tumors, while no significant difference in CR between the two groups in patients with infiltrative tumors. Conclusion: DEB-TACE showed superior efficacy to cTACE in terms of CR, OS, and PFS, particularly in patients with nodular tumors, while maintaining a similar safety profile. These findings suggest that tumor morphology could inform treatment decisions for TACE in HCC patients. [ABSTRACT FROM AUTHOR]

Introduction: Minimally invasive oncological resections have become increasingly widespread in the surgical management of cancers. However, the role of minimally invasive surgery (MIS) for gallbladder cancer (GBC) remains unclear. We aim to perform a systematic review and network meta-analysis of existing literature to evaluate the safety and feasibility of laparoscopic and robotic surgery in the management of GBC compared to open surgery (OS) by comparing outcomes. Methods: A literature search of the PubMed/MEDLINE (2000 to December 2021) and EMBASE (2000 to December 2021) databases was conducted. The primary outcome studied was overall survival, and secondary outcomes studied were postoperative morbidity, severe complications, incidence of bile leak, length of hospital stay, operation time, R0 resection rate, local recurrence and lymph node yield. Results: Thirty-two full-text articles met the eligibility criteria and were included in the final analysis with a total of 5883 patients undergoing either OS or MIS (laparoscopic or robotic) for GBC. 1- and 2-stage meta-analyses did not reveal any significant differences between OS, laparoscopic and robotic surgery in terms of overall survival, R0 resection, lymph node harvest, local recurrence and post-operative complications. Patients who underwent OS had significantly longer hospitalization stay and intra-operative blood loss compared to those who underwent laparoscopic or robotic surgery. Network meta-analysis did not reveal any significant differences between post-operative and survival outcomes of laparoscopic vs robotic surgery groups. Conclusion: This network meta-analysis suggests that both laparoscopic and robotic surgery are safe and effective approaches in the surgical management of GBC, with post-operative and survival outcomes comparable to OS. An MIS approach may also lead to shorter hospitalization stay, less intraoperative blood loss and post-operative complications compared to OS. There was no obvious benefit of either MIS approach (laparoscopic versus robotic) over the other. [ABSTRACT FROM AUTHOR]

Background: Esophageal cancer posed significant global health challenges, particularly due to poor survival rates, especially in advanced stages. Primary endoscopic resection had emerged as an alternative treatment for early esophageal cancer, aiming to preserve organ function and reduce surgical morbidity. Methods: This retrospective multicenter cohort study included 334 patients with early esophageal cancer (T1a-b, N0) from 30 French-speaking European centers between 2000 and 2010. Patients underwent either primary endoscopic resection followed by esophagectomy (E group, n = 36) or esophagectomy alone (S group, n = 298). Cox proportional hazards models adjusted for TNM stage and propensity score weighting were used to assess the impact of primary endoscopic resection on recurrence-free survival (RFS), overall survival (OS), and postoperative complications. Results: Primary endoscopic resection did not significantly influence RFS (adjusted HR 0.92, 95% CI 0.31 to 2.68, p = 0.88) or OS (adjusted HR 1.06, 95% CI 0.35 to 3.13, p = 0.92) compared to esophagectomy alone. Initial higher thromboembolic complications in the endoscopic resection group were not significant after adjustment (adjusted OR 4.73, 95% CI 0.34 to 64.27, p = 0.24). Conclusions: Primary endoscopic resection followed by esophagectomy for early esophageal cancer did not alter oncological outcomes or overall survival in this retrospective cohort. These findings supported the role of primary endoscopic resection as a safe initial treatment strategy, warranting validation in larger prospective studies. Registration: Our study was registered retrospectively on the Clinicaltrials.com website under the identifier NCT 01927016. We acknowledge the importance of prospective registration and regret that this was not done before the commencement of the study [ABSTRACT FROM AUTHOR]

Background: To evaluate the perioperative, oncological, and functional outcomes of reproductive organ-preserving radical cystectomy (ROPRC) compared to standard radical cystectomy (SRC) in the treatment of female bladder cancer. Methods: A systematic search was conducted in November 2023 across several scientific databases. We executed a systematic review and cumulative meta-analysis of the primary outcomes of interest, adhering to the PRISMA and AMSTAR guidelines. The study was registered in PROSPERO (CRD42024501522). Results: The meta-analysis included 10 studies with a total of 2015 participants. ROPRC showed a significant reduction in operative time and postoperative fasting period compared to SRC (MD − 45.69, 95% CI − 78.91 ~ − 12.47, p = 0.007, and MD − 0.69, 95% CI − 1.25 ~ − 0.13, p = 0.02, respectively). Functional outcomes, both daytime continence rate (OR 4.94, 95% CI 1.53 ~ 15.91, p = 0.008) and nighttime continence rate (OR 5.91, 95% CI 1.94 ~ 18.01, p = 0.002), and sexual function measured by the Female Sexual Function Index (MD 5.72, 95% CI 0.19 ~ 11.26, p = 0.04), were significantly improved in the ROPRC group. There were no significant differences between ROPRC and SRC in terms of estimated blood loss, length of hospital stay, overall postoperative complications, minor complications or major complications. Oncologically, both procedures showed comparable outcomes with no significant differences in positive surgical margins, tumor recurrence rates, overall survival, cancer-specific survival, recurrence-free survival, or progression-free survival. Conclusions: ROPRC is a viable and effective alternative to SRC in female bladder cancer patients, offering enhanced functional outcomes and similar oncological safety. These findings suggest that ROPRC can improve the quality of life in female bladder cancer patients without compromising the efficacy of cancer treatment. [ABSTRACT FROM AUTHOR]

Background: Laparoscopic distal gastrectomy (LDG) has become a common procedure for treating advanced gastric cancer (AGC) in China. However, there is uncertainty regarding its oncological outcomes compared to open distal gastrectomy (ODG). This study aims to compare the 3-year disease-free survival (DFS) rates among patients who underwent surgery for AGC in northern China. Methods: A multicenter, non-inferiority, open-label, parallel, randomized clinical trial was conducted to evaluate patients with AGC who were eligible for distal gastrectomy at five tertiary hospitals in North China. In this trial, patients were randomly assigned preoperatively to receive either LDG or ODG in a 1:1 allocation ratio. The primary endpoint was postoperative morbidity and mortality within 30 days and the secondary endpoint was the 3-year DFS rate. This trial has been registered at ClinicalTrials.gov (Identifier: NCT02464215). Results: A total of 446 patients were randomly allocated to LDG (n = 223) or ODG group (n = 223) between March 2014 and August 2017. After screening, a total of 214 patients underwent the open surgical approach, while 216 patients underwent laparoscopic surgery. The 3-year DFS rate was 85.9% for the LDG group and 84.72% for the ODG group, with no significant statistical difference (Hazard ratio 1.12; 95% CI 0.68–1.84, P = 0.65). Body mass index (BMI) < 25 kg/m2, advanced pathologic T4, and pathologic N2-3 category were confirmed as independent risk factors for DFS in the Cox regression. Conclusions: In comparison to ODG, LDG with D2 lymphadenectomy yielded similar outcomes in terms of 3-year DFS rates among patients diagnosed with AGC. [ABSTRACT FROM AUTHOR]

Myxopapillary ependymomas (MPEs) are rare spinal cord tumors with low rates of metastasis outside of the neuraxis. Gross total resection of MPEs can significantly improve progression-free survival; however, adjunctive treatment remains unstandardized. A 29-year-old female with a history of spina bifida occulta surgical correction and lower back pain presented with dyspnea and tachycardia. A large pulmonary artery mass was discovered consistent with pulmonary thromboembolism. It was subsequently determined to be an intravascular metastasis secondary to sacral MPE. Standardization of MPE treatment and clinical suspicion of spinal neoplasm in the setting of chronic back pain with undetermined origin are of value. [ABSTRACT FROM AUTHOR]

Objective: We aim to report the epidemiology, surgical outcomes, and survival rates of pediatric patients with posterior fossa tumors in a large single-center case series. Methods: A retrospective analysis was conducted on pediatric patients who underwent surgical treatment for posterior fossa tumors between January 2011 and January 2019. Results: A total of 135 pediatric patients, with an average age of 7.5 years at diagnosis and a mean follow-up of 35.7 months, were included in the study. Most tumors were located within the midline, with ventriculomegaly observed in 71.4% of the patients. Pilocytic astrocytomas encompassed the majority of tumors (34.1%), followed by medulloblastomas (27.4%) and ependymomas (11.8%). Gross total resection (GTR) was achieved in 71.8% of the patients, with a recurrence rate of 20%. Surgical complications were observed in 25.9% of the patients. GTR significantly impacted 5-year overall survival (OS) and 4-year progression-free survival (PFS) in patients with posterior fossa tumors. Patients who underwent GTR had a 5-year OS of 89.7%, compared to 72.7% for near-total resection and 70.8% for subtotal resection. The 4-year PFS for patients who underwent GTR was 82.5%, whereas it was 63.6% for patients who underwent near-total resection and 54.2% for patients who underwent subtotal resection. Conclusion: Surgical resection remains the main treatment for pediatric posterior fossa tumors, and higher resection rates are linked to better survival outcomes. Despite limited resources for molecular diagnosis, our institution has demonstrated that a specialized neurooncological center with a high surgical volume can still achieve favorable survival outcomes for these patients.

Objective: To estimate the comparative efficacy of ciltacabtagene autoleucel (cilta-cel) versus idecabtagene vicleucel (ide-cel) in patients with relapsed/refractory multiple myeloma (RRMM) treated with 2–4 prior lines of therapy. Methods: Matching adjusted indirect comparison (MAICs) were performed using individual patient-level data (IPD) for cilta-cel from CARTITUDE-1 and CARTITUDE-4 and published aggregated data for ide-cel from KarMMa-3. Cilta-cel patients who met inclusion criteria from KarMMa-3 were selected, and outcomes were compared against data for ide-cel using simulated IPD derived from aggregate-level data from KarMMa-3. Patient characteristics were adjusted by reweighting cilta-cel IPD to match the distribution of prognostic factors in KarMMa-3. Comparative efficacy was estimated for response outcomes using a weighted logistic regression analysis and for progression-free survival using a weighted Cox proportional hazards model. Results: Patients treated with cilta-cel were 1.2 times more likely to achieve overall response (relative response ratio [RR]: 1.18 [95% confidence interval: 1.03–1.34]; p = 0.04), 1.3 times more likely to achieve very good partial response or better (RR: 1.34 [1.15–1.57]; p = 0.003), and 1.9 times more likely to achieve complete response or better (RR: 1.91 [1.54–2.37]; p < 0.0001) versus ide-cel patients from KarMMa-3. Cilta-cel was associated with a significant 49% reduction in risk of disease progression or death versus ide-cel (hazard ratio: 0.51 [95% confidence interval: 0.31, 0.84]; p = 0.0078). Conclusion: For patients with triple-class exposed RRMM treated with 2–4 prior lines of treatment, cilta-cel was found to provide superior clinical benefit over ide-cel in terms of response and progression-free survival.

This article discusses the occurrence of pericardial events in patients receiving the drug ibrutinib for chronic lymphocytic leukemia (CLL) in two clinical trials. Pericardial events, such as pericardial effusion, pericarditis, and tamponade, were found to occur more frequently in patients treated with ibrutinib monotherapy compared to those treated with ibrutinib in combination with anti-CD20 therapy. However, further research is needed to determine if the rates of pericardial toxicity differ based on the administration of ibrutinib with other therapies. The authors stress the importance of understanding these adverse events to guide treatment decisions and improve patient outcomes. [Extracted from the article]

At the time of AtTEnd trial design, standard treatment for advanced or recurrent endometrial cancer included carboplatin and paclitaxel chemotherapy. This trial assessed whether combining atezolizumab with chemotherapy might improve outcomes in this population. AtTEnd was a multicentre, double-blind, randomised, placebo-controlled, phase 3 trial done in 89 hospitals in 11 countries across Europe, Australia, New Zealand, and Asia. Enrolled patients were aged 18 years or older, and had advanced or recurrent endometrial carcinoma or carcinosarcoma, an Eastern Cooperative Oncology Group performance status of 0–2, and received no previous systemic chemotherapy for recurrence. Patients were randomly assigned (2:1) using an interactive web response system (block size of six) to either atezolizumab 1200 mg or placebo given intravenously with chemotherapy (carboplatin at area under the curve of 5 or 6 and paclitaxel 175 mg/m2 intravenously on day 1 every 21 days) for 6–8 cycles, then continued until progression. Stratification factors were country, histological subtype, advanced or recurrent status, and mismatch repair (MMR) status. Participants and treating clinicians were masked to group allocation. The hierarchically tested co-primary endpoints were progression-free survival (in patients with MMR-deficient [dMMR] tumours, and in the overall population) and overall survival (in the overall population). Primary analyses were done in the intention-to-treat population, defined as all randomly assigned patients who gave their full consent to participation in the study and data processing. Safety was assessed in all patients included in the intention-to-treat population who received at least one dose of study treatment. Here, we report the primary progression-free survival and the interim overall survival results. This study is ongoing and is registered with ClinicalTrials.gov , NCT03603184. Between Oct 3, 2018, and Jan 7, 2022, 551 patients were randomly assigned to atezolizumab (n=362) or placebo (n=189). Two patients in the atezolizumab group were excluded from all analyses due to lack of consent. Median follow-up was 28·3 months (IQR 21·2–37·6). 81 (23%) patients in the atezolizumab group and 44 (23%) patients in the placebo group had dMMR disease by central assessment. In the dMMR population, median progression-free survival was not estimable (95% CI 12·4 months–not estimable [NE]) in the atezolizumab group and 6·9 months (6·3–10·1) in the placebo group (hazard ratio [HR] 0·36, 95% CI 0·23–0·57; p=0·0005). In the overall population, median progression-free survival was 10·1 months (95% CI 9·5–12·3) in the atezolizumab group and 8·9 months (8·1–9·6) in the placebo group (HR 0·74, 95% CI 0·61–0·91; p=0·022). Median overall survival was 38·7 months (95% CI 30·6–NE) in the atezolizumab group and 30·2 months (25·0–37·2) in the placebo group (HR 0·82, 95% CI 0·63–1·07; log-rank p=0·048). The p value for the interim analysis of overall survival did not cross the stopping boundary; therefore, the trial will continue until the required number of events are recorded. The most common grade 3–4 adverse events were neutropenia (97 [27%] of 356 patients in the atezolizumab group vs 51 [28%] of 185 in the placebo group) and anaemia (49 [14%] vs 24 [13%]). Treatment-related serious adverse events occurred in 46 (13%) patients in the atezolizumab group and six (3%) patients in the placebo group. Treatment-related deaths occurred in two patients (pneumonia in one patient in each group). Atezolizumab plus chemotherapy increased progression-free survival in patients with advanced or recurrent endometrial carcinoma, particularly in those with dMMR carcinomas, suggesting the addition of atezolizumab to standard chemotherapy as first-line treatment in this specific subgroup.

Purpose: Atezolizumab/bevacizumab (atezo-bev) is the first-line chemotherapy for patients with unresectable hepatocellular carcinoma (HCC). However, hepatic artery infusion chemotherapy (HAIC) can be used as an alternative. Our aim was to compare the prognosis of HAIC treatment between newly diagnosed patients and patients treated after failure of atezo-bev. Methods: We retrospectively assessed 73 patients with HCC treated with HAIC between January 2022 and September 2023. Fifty-seven patients were treated with HAIC at initial diagnosis, while 16 were treated with HAIC after first-line atezo-bev combination chemotherapy. We evaluated tumor responses, such as overall survival (OS), progression-free survival (PFS), and objective response rate (ORR). Results: No significant difference was observed in either OS or PFS between patients with HCC treated with HAIC at the initial diagnosis and those treated after atezo-bev treatment failure. However, the ORR of the initial HAIC group was 19.6% and that of the HAIC group after atezo-bev therapy failure was 43.6%, which was a statistically significantly difference. Conclusion: Although no significant difference was observed for OS and PFS, the ORR of patients in the HAIC group after the failure of atezo-bev therapy was superior to that of newly diagnosed patients. HAIC may prolong survival in patients with HCC after atezo-bev treatment failure. [ABSTRACT FROM AUTHOR]

Background: This study aimed to investigate the prognostic value of the Gustave Roussy Immune score (GRIm-score) in platinum-refractory metastatic urothelial carcinoma (UC) treated with pembrolizumab. Methods: This multicenter retrospective study (YUSHIMA study) evaluated 331 patients with metastatic UC treated with pembrolizumab after platinum-based chemotherapy between January 2018 and June 2023 at 13 institutions. We collected pretreatment variables, including the GRIm-score based on serum albumin, lactate dehydrogenase, and neutrophil-to-lymphocyte ratio. The patients were divided into low and high GRIm-score groups. Prognostic factors for overall survival (OS) and progression-free survival (PFS) were determined using the multivariate Cox proportional hazard model. Results: During the median follow-up period of 7.3 months, 278 (84%) patients showed disease progression, and 223 (67%) died from any cause. Multivariate analysis revealed that the high GRIm-score group was an independent and significant adverse prognostic factor of both OS and PFS (hazard ratio, 1.65 and 1.82, respectively; both p < 0.001) along with Eastern Cooperative Oncology Group Performance Status of ≥ 2 (both p < 0.001), presence of visceral metastasis (both p < 0.001), and hemoglobin of < 9.2 g/dL (p = 0.030 and p = 0.038). C-reactive protein of > 42 mg/L was a significant prognostic factor for OS (p = 0.001). Conclusion: The GRIm-score is an independent prognostic marker for survival outcomes in patients with platinum-refractory metastatic UC treated with pembrolizumab. [ABSTRACT FROM AUTHOR]
