Real-world Outcomes Among Patients Treated With Gemcitabine-based Therapy Post-FOLFIRINOX Failure in Advanced Pancreatic Cancer

Objectives: Limited evidence exists for chemotherapy selection in advanced pancreatic cancer (APC) after first-line FOLFIRINOX. Second-line gemcitabine/nab-paclitaxel (GEMNAB) is publicly funded in the Canadian provinces of Alberta (AB) and Manitoba (MB), but not in British Columbia (BC). We compared population-based outcomes by region to examine the utility of second-line GEMNAB versus gemcitabine (GEM) alone. Methods: We identified patients treated with first-line FOLFIRINOX between 2013 and 2015 across BC, AB, and MB. Baseline characteristics and treatment regimens were compared between AB/MB and BC. Survival outcomes were assessed by the Kaplan-Meier method and compared with log-rank test. Results: A total of 368 patients were treated with first-line FOLFIRINOX (143 AB/MB, 225 BC): median age 61 (interquartile range: 55 to 68) years, 42% comprising female individuals, and 67% with metastatic disease. Receipt of second-line therapy was 48% in AB/MB versus 44% in BC (P=0.35), and time from diagnosis to second-line therapy was 7.7 (AB/MB) versus 9.4 months (BC; P=0.1). Distribution of second-line GEM use: 73% GEMNAB, 23% GEM (AB/MB) versus 27% GEMNAB, 66% GEM (BC; P
