RESUMO
BACKGROUND: Nivolumab has changed the treatment of advanced gastric cancer (AGC). Nivolumab shows better outcomes compared to best supportive care among AGC patients who received at least two prior regimens. However, there are no reliable data regarding AGC patients with poor performance status (PS) who received nivolumab. We investigated the efficacy and safety of nivolumab among AGC patients with poor PS. METHODS: We retrospectively collected clinicopathologic data from patients with AGC who underwent nivolumab monotherapy at our institution from October 2017 to June 2019. RESULTS: Forty-nine AGC patients who received nivolumab were assessed. Twenty-seven patients had PS 0 or 1 (Good group) and 22 had PS 2 or 3 (Poor group). The median progression-free survival and overall survival durations were 2.0 and 6.0 months in the Good group, respectively, and 1.2 and 2.8 months in the Poor group, respectively. The overall survival was significantly shorter in the Poor group (6.0 vs 2.8 months, p = 0.0255). The disease control rates were 23 and 9% in the Good and Poor groups, respectively. Thirty-three percent of patients experienced immune-related adverse events in the Good group, and 18% in the Poor group. CONCLUSION: Nivolumab is feasible but insufficient as third- or later-line treatment for AGC patients with poor PS.

OBJECTIVES: There is no standard chemotherapy for advanced pancreatic cancer (APC) after gemcitabine plus nab-paclitaxel (GP) failure. The aim of this study was to evaluate the efficacy and safety of FOLFIRINOX (5-Fluorouracil, leucovorin, irinotecan, and oxaliplatin) (5-Fluorouracil, leucovorin, irinotecan, and oxaliplatin) (FFX) and modified FFX (mFFX) for APC patients after GP failure. METHODS: We retrospectively evaluated the efficacy and safety of FFX in APC patients who were refractory or intolerant of GP. RESULTS: Between July 2014 and October 2018, 23 patients received FFX after failure of GP. The overall response rate (RR) was 23%, and the disease control rate (DCR) was 68%. The median progression-free survival (PFS) was 5.3 months (95% confidence interval, 2.5-8.9), and the median overall survival (OS) was 12.1 months (95% confidence interval, 4.0-14.2). Twelve patients received FFX, and 11 patients received mFFX. In the FFX group, the RR was 9%, the DCR was 73%, the PFS was 5.3 months, and the OS was 6.9 months. In the mFFX group, the RR was 23%, the DCR was 64%, the PFS was 4.3 months, and the OS was 12.8 months. There was no significant difference between the groups. CONCLUSIONS: FOLFIRINOX has potential activity for patients with APC in whom GP failed.
