Abstract

Purpose: To verify the experience of the GOIM in the treatment of advanced colorectal cancer patients with the FOLFIRI combination therapy. Patients and methods: Patients entered in three consecutive trials of the GOIM (protocols no. 9706, 9901, and 2301) were reported in this analysis. A total of 287 chemotherapy-naive patients were treated with FOLFIRI regimen: Irinotecan 180mg/m2 on day 1 with LV5FU2 regimen (LV at 100mg/m2 administered as a 2-hour infusion before FU at 400mg/m2 as an intravenous bolus injection, and FU at 600mg/m2 as a 22-hour infusion immediately after 5FU bolus injection on day 1 and 2); the treatment was repeated every 2 weeks. Results: 287 patients entered in these three trials, and 264 (92%) were evaluable for response. The overall response rate was 34.5% (95% confidence interval [CI]: 29% to 40%). When only assessable patients were analyzed, overall response rate was 37% (95% CI: 31% to 43%). Median time to progression, median duration of response and survival were 7 months, 10.5 months and 14 months, respectively. All but three patients were evaluable for toxicity which was globally mild; grade 3-4 toxicity was uncommon, and gastrointestinal disturbances were the most common. Conclusions: FOLFIRI regimen is effective and well-tolerated as first-line treatment in patients with advanced colorectal cancer. Further studies needed to evaluate the improvement in results with the addition of new drugs to this combination therapy.
