Purpose:
Liver metastasis (LM) is reported in approximately 40% of patients with advanced/ metastatic gastric/gastroesophageal junction adenocarcinoma (metastatic esophagogastric adenocarcinoma; mGEA) and is associated with a worse prognosis. This post-hoc analysis from the RAINBOW trial reported the efficacy, safety, and biomarker outcomes of ramucirumab and paclitaxel combination treatment (RAM+PAC) in patients with (LM+) and without (LM−) LM at baseline.
Materials and Methods:
Patients (n=665) were randomly assigned on a 1:1 basis to receive either RAM+PAC (LM+: 150, LM−: 180) or placebo and paclitaxel (PL+PAC) (LM+: 138, LM−: 197). The overall survival (OS) and progression-free survival (PFS) were evaluated using stratified Kaplan–Meier and Cox regression models. The correlation of dichotomized biomarkers (VEGF-C, D; VEGFR-1,2) with efficacy in the LM+ versus LM− subgroups was analyzed using the Cox regression model with reported interaction P-values.
Results:
The presence of LM was associated with earlier progression than those without LM, particularly in patients receiving PL+PAC (hazard ratio [HR], 1.68). RAM+PAC treatment improved OS and PFS irrespective of LM status but showed greater improvement in LM+ than that in LM− (OS HR, 0.71 [LM+] vs. 0.88 [LM−]; PFS HR, 0.47 [LM+] vs. 0.76 [LM−]).Treatment-emergent adverse events were similar between patients with and without LM. No predictive relationship was observed between biomarker levels (VEGF-C, D; VEGFR-1,2) and efficacy outcome (OS, PFS) (all interaction P-values >0.05).
Conclusions
RAM provided a significant benefit, irrespective of LM status; however, its effect was numerically stronger in patients with LM. Therefore, RAM+PAC is a clinically meaningful therapeutic option for patients with mGEA and LM.

PURPOSE: To identify baseline prognostic factors for survival in patients with disease progression, during or after chemotherapy for the treatment of advanced gastric or gastroesophageal junction (GEJ) cancer. MATERIALS AND METHODS: We pooled data from patients randomized between 2009 and 2012 in 2 phase III, global double-blind studies of ramucirumab for the treatment of advanced gastric or GEJ adenocarcinoma following disease progression on first-line platinum- and/or fluoropyrimidine-containing therapy (REGARD and RAINBOW). Forty-one key baseline clinical and laboratory factors common in both studies were examined. Model building started with covariate screening using univariate Cox models (significance level=0.05). A stepwise multivariable Cox model identified the final prognostic factors (entry+exit significance level=0.01). Cox models were stratified by treatment and geographic region. The process was repeated to identify baseline prognostic quality of life (QoL) parameters. RESULTS: Of 1,020 randomized patients, 953 (93%) patients without any missing covariates were included in the analysis. We identified 12 independent prognostic factors of poor survival: 1) peritoneal metastases; 2) Eastern Cooperative Oncology Group (ECOG) performance score 1; 3) the presence of a primary tumor; 4) time to progression since prior therapy <6 months; 5) poor/unknown tumor differentiation; abnormally low blood levels of 6) albumin, 7) sodium, and/or 8) lymphocytes; and abnormally high blood levels of 9) neutrophils, 10) aspartate aminotransferase (AST), 11) alkaline phosphatase (ALP), and/or 12) lactate dehydrogenase (LDH). Factors were used to devise a 4-tier prognostic index (median overall survival [OS] by risk [months]: high=3.4, moderate=6.4, medium=9.9, and low=14.5; Harrell's C-index=0.66; 95% confidence interval [CI], 0.64–0.68). Addition of QoL to the model identified patient-reported appetite loss as an independent prognostic factor. CONCLUSIONS: The identified prognostic factors and the reported prognostic index may help clinical decision-making, patient stratification, and planning of future clinical studies.

Background:Capecitabine and irinotecan combination therapy (XELIRI) has been examined at various dose levels to treat metastatic colorectal cancer (mCRC). Recently, in the Association of Medical Oncology of the German Cancer Society (AIO) 0604 trial, tri?weekly XELIRI plus bevacizumab, with reduced doses of irinotecan (200mg/m2 on day 1) and capecitabine (1600mg/m2 on days 1–14), repeated every 3weeks, has shown favorable tolerability and effcacy which were comparable to those of capecitabine and oxaliplatin (XELOX) plus bevacizumab. The doses of capecit?abine and irinotecan in the AIO trial are considered optimal. In a phase I/II study, XELIRI plus bevacizumab (BIX) as second?line chemotherapy was well tolerated and had promising effcacy in Japanese patients. Methods:The Asian XELIRI ProjecT (AXEPT) is an East Asian collaborative, open?labelled, randomized, phase III clinical trial which was designed to demonstrate the non?inferiority of XELIRI with or without bevacizumab versus standard FOLFIRI (5?lfuorouracil, leucovorin, and irinotecan combination) with or without bevacizumab as second?line chemo?therapy for patients with mCRC. Patients with 20years of age or older, histologically conifrmed mCRC, Eastern Coop?erative Oncology Group performance status 0–2, adequate organ function, and disease progression or intolerance of the ifrst?line regimen will be eligible. Patients will be randomized (1:1) to receive standard FOLFIRI with or with?out bevacizumab (5mg/kg on day 1), repeated every 2weeks (FOLIRI arm) or XELIRI with or without bevacizumab (7.5mg/kg on day 1), repeated every 3weeks (XELIRI arm). A total of 464 events were estimated as necessary to show non?inferiority with a power of 80% at a one?sided α of 0.025, requiring a target sample size of 600 patients. The 95% conifdence interval (CI) upper limit of the hazard ratio was pre?speciifed as less than 1.3. Conclusion:The Asian XELIRI ProjecT is a multinational phase III trial being conducted to provide evidence for XELIRI with or without bevacizumab as a second?line treatment option of mCRC.

Purpose: Naldemedine is a peripheral µ-opioid receptor antagonist, including the treatment of opioid-induced constipation (OIC) . However, diarrhea is known as its side effect. We conducted a study focusing on the administration period of opioid analgesics before the start of naldemedine to clear predictors of diarrhea due to Naldemedine. Method: All data were retrospectively collected from the electronic medical record system. We investigated patients who initially administrated naldemedine at Nagasaki University Hospital from June 1 2017 to March 31 2019. Result: One hundred thirty-two patients were subject of investigation. The incidence of diarrhea was 25.0%. The result of the multivariate analysis showed that significant predictors of diarrhea were associated with the opioid analgesics usage period longer than 7 days before naldemedine initiation (odds ratio: 3.76, 95% confidence interval: 1.53-9.20, p=0.004). Discussion: When naldemedine was used for OIC, diarrhea may be avoided by using within 7 days after opioid analgesics.
