Abstract
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. We retrospectively evaluated the efficacy and safety of FFX in APC patients who were refractory or intolerant of GP. 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. FOLFIRINOX has potential activity for patients with APC in whom GP failed.
