Background: Gemcitabine (Gem) alone or with Nab-paclitaxel (Gem-Nab) is used as second-line treatment for metastatic pancreatic adenocarcinoma (mPA) after FOLFIRINOX (FFX) failure; however, no comparative data exist. This study evaluates the efficacy and safety of adding Nab-paclitaxel to Gem for mPA after FFX failure., Methods: In this retrospective real-world multicenter study, from 2011 to 2019, patients with mPA receiving Gem-Nab (Gem 1000 mg/m² + Nab 125 mg/m², 3 out of 4 weeks) or Gem alone were included after progression on FFX., Results: A total of 427 patients were included. Patients receiving Gem-Nab had more metastatic sites, peritoneal disease and less PS 2 (24% vs. 35%). After median follow-up of 22 months, Gem-Nab was associated with better disease control rate (DCR) (56% vs. 32%; P < 0.001), progression-free survival (PFS) (3.5 vs. 2.3 months; 95% CI: 0.43-0.65) and overall survival (OS) (7.1 vs. 4.7 months; 95% CI: 0.53-0.86). After multivariate analysis, Gem-Nab and PS 0/1 were associated with better OS and PFS. Grade 3/4 toxicity was more frequent with Gem-Nab (44% vs. 29%)., Conclusion: In this study, Gem-Nab was associated with better DCR, PFS and OS compared with Gem alone in patients with mPA after FFX failure, at the cost of higher toxicity., (© 2022.
