Objective:
The aim of the study is to compare the efficacy and safety of 3 chemotherapy regimens used as first-line treatments in the real-life management of metastatic pancreatic cancer.
Methods:
A total of 218 patients were included in this multicenter study. Gemcitabine (Gem, n = 71), gemcitabine-cisplatin (Gem-Cis, n = 91), and FOLFIRINOX (a combination of leucovorin, 5-fluorouracil, irinotecan, and oxaliplatin [FFX], n = 56) treatments were compared.
Results:
Overall response rate was significantly higher in the FFX group (50.0%) than in the Gem (28.2%) and Gem-Cis (27.5%) groups (P = 0.010). Median progression-free survival (8.4 vs 4.6 and 5.5 months, respectively, P < 0.001) and overall survival (16.4 vs 8.1 and 8.7 months, respectively, P = 0.002) were significantly longer in the FFX group than in the Gem and Gem-Cis groups. Toxicity of any grade was noted in 46 (64.8%), 56 (61.5%), and 49 (87.5%) patients in the Gem, Gem-Cis, and FFX groups, respectively (P = 0.003).
Conclusions:
In our study, FFX regimen provides a significant advantage over the other treatment regimens in terms of response rates and survival. Treatment toxicity was more frequent but manageable with the FFX regimen.
