Background:We designed an open-label, noncomparative phase II study to assess the safety and efficacy of first-line treatment with trifluridine/tipiracil plus bevacizumab (TTeB) and capecitabine plus bevacizumab (CeB) in untreated patients with unresectable metastatic colorectal cancer (mCRC) who were not candidates for combination with cytotoxic chemotherapies. Patients and methods: From 29 April 2016 to 29 March 2017, 153 patients were randomly assigned (1:1) to either TTeB (N ¼ 77) or CeB (N ¼ 76). The primary end point was progression-free survival (PFS). The primary PFS analysis was performed after 100 events (radiological progression or death) were observed. Secondary end points included overall survival (OS), quality of life (QoL; QLQ-C30 and QLQ-CR29 questionnaires), and safety. Results: Median (range) duration of treatment was 7.8 (6.0e9.7) months and 6.2 (4.1e9.1) months in the TTeB and CeB groups, respectively. Median (range) PFS was 9.2 (7.6e11.6) and 7.8 (5.5e10.1) months, respectively. Median (range) OS was 18 (15.2 to NA) and 16.2 (12.5 to NA) months, respectively. QoL questionnaires showed no relevant changes over time for either treatment. Therapies were well tolerated. Patients receiving TTeB had more grade !3 neutropenia (47% versus 5% with CeB). Patients receiving CeB had more grade !3 handefoot syndrome (12% versus 0% with TTeB) and grade !3 diarrhea (8% versus 1% with TTeB), consistent with the known safety profiles of these agents. Conclusion: TTeB treatment showed promising clinical activity in untreated patients with unresectable mCRC ineligible for intensive therapy, with an acceptable safety profile and no clinically relevant changes in QoL.

Gastric cancer remains one among the leading causes of cancer-related deaths, regardless of its decreasing incidence and newly available treatment options. Most patients present at an advanced stage and are treated with upfront systemic chemotherapy. Those patients receiving first-line therapy may initially respond to treatment, but many of them relapse over time. In such condition, second-line treatment for disease progression remains the only available option. Although there exists no standard approach in the second-line setting, several phase III trials have shown modest survival benefit in patients receiving irinotecan, taxane and ramucirumab over the best supportive care or active agents. This review analyzes the currently available treatment regimens and future directions of research in the second-line setting for metastatic gastric cancer with the best available evidence. Additionally, the prognostic factors that influence patient survival in those receiving second-line therapy are discussed.
Epstein-Barr virus-associated gastric cancer [EBV-associated GC, EBV( +) GC] is a distinct molecular subtype of gastrointestinal (GI) cancers. It accounts for up to 10% of all molecular subtypes of gastric cancer (GC). It has unique genetic and epigenetic features, which determine its definitive phenotype with male and younger age predominance, proximal stomach localization, and diffuse adenocarcinoma histology. EBV( +) GC also has a unique epigenetic profile and mutational status with frequent mutations of PIK3CA, ARID1A and BCOR, and PD-L1 and PD-L2 amplifications, as well. The aim of this review is to highlight clinical significance of EBV( +) GC and prognostic role of EBV infection, and to determine potentially appropriate drug therapy for this disease.
The aim of our study was to determine the effect of homologous recombination deficiency (HRD) on prognosis and efficacy of platinum-based chemotherapy in patients with pancreatic cancer (PC). We performed PubMed and Embase database queries. We included 4 studies into the meta-analysis and 16 studies in the systematic review. Our systematic analysis showed that the average weighted median overall survival (OS) in patients with HRD with advanced PC was 19.8 and 15.6 months in patients without HRD. With platinum-based chemotherapy, the average weighted median OS in patients with HRD was 23.8 and 17.1 months in patients without HRD. Without platinum-based chemotherapy, the average weighted median OS in patients with HRD was 8.3 and 12.0 months in patients without HRD. For resected PC, our meta-analysis demonstrated that HRD status did not affect the prognosis (HR 1.03, 95% CI 0.46 to 2.33), but results were rather heterogeneous (I2=83%, p=0.003). Our systematic analysis showed that the average weighted median OS in patients with HRD was 34.6 and 27.0 months in patients without HRD. With platinum-based chemotherapy, the average weighted median OS in patients with HRD was 46.1 and 36.3 months in patients without HRD. Without platinum-based chemotherapy, the average weighted median OS in patients with HRD was 24.2 and 42.9 months in patients without HRD. Results of our meta-analysis and systematic review support the idea of platinum use in patients with HRD both in resected and metastatic PCs, although a randomised trial is warranted to make a more reliable conclusion.PROSPERO registration numberCRD42019121914.
This study evaluated safety and quality of life in patients with metastatic colorectal cancer undergoing treatment with aflibercept and FOLFIRI (fluorouracil, leucovorin, irinotecan). Most patients treated with this combination experienced either improvement or stability in quality of life scores. Aflibercept plus FOLFIRI is tolerable in the treatment of patients with metastatic colorectal cancer with a safety profile similar to that seen in previous studies of these individual medications. Background: The objectives of this study were to evaluate the safety profile of aflibercept and health-related quality of life (HRQL) in patients with metastatic colorectal cancer (mCRC) provided with aflibercept access before marketing authorization. Patients and Methods: Patients received aflibercept followed by FOLFIRI (fluorouracil, leucovorin, irinotecan) on day 1 of a 2-week cycle until disease progression, unacceptable toxicity, death, or patient/investigator decision to discontinue. Treatment-emergent adverse events (TEAEs) were evaluated, and HRQL was assessed at baseline, cycle 3, and every other cycle using the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30, EORTC QLQ-CR29, and EuroQol 5-Dimensions 3-Levels questionnaires (NCT01571284).
