Background: The clinical phase III first-line trials MPACT and PRODIGE4/ACCORD11 in metastatic PAC pts have changed the treatment paradigm. We aimed to analyse the impact of these regimens on the treatment landscape and survival of advanced PAC pts. Methods: In this single institutional retrospective cohort analysis patient characteristics and overall survival (OS) from all pts with advanced PAC treated between 01/2011-12/2017 were analysed. Survival analyses were performed by Kaplan-Meier method. Results: A total of 301 pts started a systemic treatment in the observation period. Concerning the first-line treatment, there was a clear shift from four different main regimens (gemcitabine/nab-paclitaxel (G+nab-P), FOLFIRINOX, gemcitabine/oxaliplatin +/- erlotinib, gemcitabine mono) to only two (G+Nab-P, FOLFIRINOX), that made up more than 80% of the administered first-line treatments in each of the groups (2011-2013 vs. 2014-2017). The rate for first-line FOLFIRINOX treatment was balanced between the two groups (19% and 15%). G+nab-P treated pts had a median age of 66 years, 41.3% had an ECOG 1-2, the FOLFIRINOX treated pts were younger and fitter (57 years and 24.5 % ECOG 1, 0% ECOG 2). 60.7% of pts treated with G+nab-P received a second-line and 30.7% pts received a third-line treatment, while for the FOLFIRINOX pts these rates were 69.8% and 41.5%. Median OS of pts that started first-line treatment between 2011 and 2013 was 8.77 months (95% CI 6.98-10.57) and for those that started first-line treatment between 2014 and 2017 median OS was 11.07 months (95% CI 8.94 13.20) (p = 0.038, Log-Rank-Test). Conclusions: There is a clear impact of new chemotherapy regimens on the treatment landscape. Furthermore, we provide real-world evidence that since the introduction of these new treatment options, the survival of pts with advanced PAC has significantly improved.
