Randomised trial of gemcitabine versus flec regimen given intra-arterially for patients with unresectable pancreatic cancer.
Gemcitabine is considered the golden standard treatment for unresectable pancreatic adenocarcinoma. Intra-arte-rial drug administration had shown a deep rationale with some interesting results. In a multicenter phase III trial, we compared gemcitabine given weekly with a combination of 5-fluoruracil, leucovorin, epirubicin, carboplatin (FLEC) administered intra-arteriously as first-line therapy in unresectable pancreatic adenocarcinoma. Patients were randomly assigned to receive gemcitabine at a dose of 1,000 mg/m2 over 30 minutes intravenously weekly for 7 weeks, followed by 1 week of rest, then weekly for 3 weeks every 4 weeks or 5-fluoruracil 1,000 mg/m2, leucovorin 100 mg/m2, epirubicin 60 mg/m2, carboplatin 300 mg/m2 infused bolus intra-arteriously at three-weekly interval for 3 times. The primary end point was overall survival, while time to treatment failure, response rate, clinical benefit response were secondary endpoints. Sixty-seven patients were randomly allocated gemcitabine and 71 were allocated FLEC intra-arterially. Patients treated with FLEC lived for significantly longer than patients on gemcitabine (p=.036). Survival at 1 year was increased from 21% in the gemcitabine group to 35% in the FLEC group. Median survival was 7.9 months in the FLEC group and 5.8 months in the gemcitabine group. Median time to treatment failure was longer with FLEC (5.3 vs 4.2 months for FLEC vs gemcitabine respectively; p=.013). Clinical benefit was similar in both groups (17.9% for gemcitabine and 26.7% for FLEC; p=NS). CT-scan partial response was similar in both group (5.9% for gemcitabine and 14% for FLEC; p=NS). Toxicity profiles were different. Compared with gemcitabine, FLEC regimen given intra-arteriously, improved survival in patient with unresectable pancreatic adenocarcinoma.
