Abstract

Aims: To evaluate the impact of first-line mFFX-induced PN on the efficacy of second-line GnP in patients with APC.

Methods: A database containing patients with APC was retrospectively analyzed to evaluate patients who received second-line GnP after first-line mFFX failure between September 2014 and January 2021. The efficacy and safety of GnP were compared between patients with PN ≥ Grade 2 (PN group) and PN ≤ Grade 1 (non-PN group) at the start of second-line GnP. Cox proportional hazards analysis was also performed to examine the effect on overall survival (OS) and time-to-treatment failure (TTF).

Results: Fifty-nine patients (PN group, 18 patients; non-PN group, 41 patients) were included. Median OS and TTF in the PN versus non-PN group were 7.7 versus 5.7 months ( = 0.19) and 3.8 versus 2.7 months ( = 0.18), respectively. Multivariate analysis showed that PN (≥Grade 2) was not a significant factor affecting either OS (hazard ratio (HR) 0.66, 95% confidence interval [CI] 0.33-1.31, = 0.24) or TTF (HR 0.71, 95% CI 0.38-1.33, = 0.28). No significant difference was observed in the relative dose intensity of GEM or nab-PTX, and incidence of adverse events.

Conclusions: mFFX-induced PN has little impact on the efficacy and safety of second-line GnP in patients with APC. Second-line GnP could be a possible treatment option regardless of the presence of PN.
