Adjuvant intra-arterial 5-fluoruracil, leucovorin, epirubicin and carboplatin with or without systemic gemcitabine after curative resection for pancreatic adenocarcinoma.

BACKGROUND

The role of adjuvant therapy in pancreatic cancer remains controversial. Gemcitabine given systemically seems to be effective; intra-arterial chemotherapy (IAC) has a deep rationale.

PATIENTS AND METHODS

The goal was to evaluate the impact of postoperative IAC followed or not by systemic gemcitabine in patients after curative resection for pancreatic adenocarcinoma. 5-fluoruracil 750 mg sq m(-1), leucovorin 75 mg sq m(-1), epirubicin 45 mg sq m(-1), carboplatin 225 mg sq m(-1) were administered every 3 weeks into celiac axis for three cycles (FLEC regimen), then gemcitabine at the dosage of 1 g sq m(-1) on days 1, 8 and 15 every 4 weeks for 3 months (FLECG regimen).

RESULTS

Forty-seven patients entered the study. The first 24 received only IAC (FLEC regimen), the other 23 received the same intra-arterial regimen followed by systemic gemcitabine (FLECG regimen). After a median follow-up of 16.9 months, 29 patients recurred (61.7%). Median disease free survival (DFS) was 18 months and median overall survival (OS) was 29.7 months. One-year DFS was 59.4% and 1-year OS was 75.5%. Main grade 3 toxicity related to IAC was only nausea/vomiting in 4%; regarding gemcitabine, grade 3 toxicities were anaemia 8%, leukopenia 8%, thrombocitopenia 17%, nausea/vomiting 4%.

CONCLUSIONS

FLEC regimen with or without gemcitabine is active with a very mild toxicity and results are very encouraging in an adjuvant setting.
