Background: The purpose of the study was to prospectively evaluate the efficacy and tolerability of the FOLFIRI.3 regimen in patients with unresectable pancreatic adenocarcinoma.
Patients and methods: Chemotherapy-naive patients with histologically proven advanced pancreatic adenocarcinoma were treated with the FOLFIRI.3 regimen, consisting of irinotecan 90 mg/m2 as a 60-min infusion on day 1, leucovorin 400 mg/m2 as a 2-h infusion on day 1, followed by 5-fluorouracil (5-FU) 2000 mg/m2 as a 46-h infusion and irinotecan 90 mg/m2, repeated on day 3, at the end of the 5-FU infusion, every 2 weeks.
Results: Forty patients were enrolled, of whom 29 (73%) had metastatic disease. A total of 441 cycles were delivered (153). Grade 34 neutropenia occurred in 35% of the patients, accompanied by fever in two cases. Other relevant grade 34 toxic effects were nausea-vomiting (27%) and diarrhea (25%). Grade 2 alopecia occurred in 48% of the patients. There were no treatment-related deaths. The confirmed response rate was 37.5%. Stable disease was observed in 27.5% of the patients. The median progression-free and overall survivals were 5.6 months and 12.1 months, respectively. The 1-year survival rate was 51%.
Conclusion: The FOLFIRI.3 regimen seems to be active on advanced pancreatic cancer and to have a manageable toxicity profile. The lack of cross-resistance between FOLFIRI.3 and gemcitabine-based regimens allows efficient second-line therapies.
