Abstract

Background: Metastatic pancreatic ductal adenocarcinoma (PDAC) is characterized by a poor survival rate, which can be improved by systemic treatment. Consensus on the most optimal first- and second-line palliative systemic treatment is lacking. The aim of this study was to describe the use of first- and second-line systemic treatment, overall survival (OS), and time to failure (TTF) of first- and second-line treatment in metastatic PDAC in a real-world setting. Patients and Methods: Patients with synchronous metastatic PDAC diagnosed between 2015 and 2018 who received systemic treatment were selected from the nationwide Netherlands Cancer Registry. OS and TTF were evaluated using Kaplan-Meier curves with log-rank test and multivariable Cox proportional hazard analyses. Results: The majority of 1,586 included patients received FOLFIRINOX (65%), followed by gemcitabine (18%), and gemcitabine 1 nabpaclitaxel (13%) in the first line. Median OS for first-line FOLFIRINOX, gemcitabine 1 nab-paclitaxel, and gemcitabine monotherapy was 6.6, 4.7, and 2.9 months, respectively. Compared to FOLFIRINOX, gemcitabine 1 nab-paclitaxel showed significantly inferior OS after adjustment for confounders (hazard ratio [HR], 1.20; 95% CI, 1.02-1.41), and gemcitabine monotherapy was independently associated with a shorter OS and TTF (HR, 1.98; 95% CI, 1.71-2.30 and HR, 2.31; 95% CI, 1.88-2.83, respectively). Of the 121 patients who received second-line systemic treatment, 33% received gemcitabine 1 nab-paclitaxel, followed by gemcitabine (31%) and FOLFIRINOX (10%). Conclusions: Based on population-based data in patients with metastatic PDAC, treatment predominantly consists of FOLFIRINOX in the first line and gemcitabine with or without nab-paclitaxel in the second line. FOLFIRINOX in the first line shows superior OS compared with gemcitabine with or without nab-paclitaxel.
