FOLFIRINOX vs gemcitabine/nab-paclitaxel for treatment of metastatic pancreatic cancer: Single-center cohort study
Abstract
BACKGROUND FOLFIRINOX and gemcitabine plus nab-paclitaxel (Gem + nabPTX) were recently introduced for metastatic pancreatic cancer treatment. However, studies that compared these two regimens and studies in Asian populations are lacking. AIM To compare the treatment outcomes of FOLFIRINOX and Gem + nabPTX regimen for metastatic pancreatic cancer treatment in Korean population. METHODS Patients with metastatic or recurrent pancreatic cancer treated with FOLFIRINOX (n = 86) or Gem + nabPTX (n = 81) as the first-line since January 2015 were identified using the Severance Hospital Pancreatic Cancer Cohort Registry. Treatment efficacy, treatment-related adverse events and economic aspects were compared. RESULTS Patients in the FOLFIRINOX group were significantly younger (54 vs 65 years; P < 0.001) and had better performance statuses at diagnosis. The median overall survival (10.7 vs 12.1 mo; P = 0.157), progression-free survival (8.0 vs 8.4 mo; P = 0.134), and objective response rates (33.7% vs 46.9%; P = 0.067) were not significantly different when compared with Gem + nabPTX group. Grade ≥ 3 neutropenia and gastrointestinal adverse events were more common in the FOLFIRINOX group. The drug costs of both regimens were similar. CONCLUSION Treatment efficacy and economic burdens were comparable between the two regimens. But, the details of adverse event were different. Gem + nabPTX regimen might be considered preferentially in certain conditions.
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 86 participants or records.
