Folfirinox (FFX) versus gemcitabine with nab‐paclitaxel (GNP) in the first line treatment (1LTx) of metastatic pancreatic cancer (mPC): A tertiary center experience.

414Background: The efficacy of FFX and GNP as 1LTx of mPC were established in phase 3 trials against Gemcitabine alone. However, no head‐to‐head trial has been performed. This analysis was conducted to compare the use of the two regimens in the 1LTx of mPC patients (pts). Methods: Retrospective study collected data of pts diagnosed with mPC (ECOG 0‐1) that received FFX or GNP as 1LTx at the Jewish General Hospital between 2010‐2016. Pt selection for 1LTx was based in ASCO Guidelines 2016 Criteria (AGC2016). Progression free survival (PFS) and overall survival (OS) were estimated using a Kaplan Meier method. Rate of 1LTx discontinuation and start of 2LTx was compared using two‐sided Fisher's exact test. Results: Among 75 pts with mPC (median age 69), 44 (59%) received FFX and 31 (41%) received GNP. In the FFX group 57% were male and 24 pts (55%) had primary tumors localized in the pancreatic head (PTPH). The majority of patients [n = 36 (82%)] had ECOG 1 at the start of FFX. The most common grade 3‐4 adver...
