AbstractAim: Patients with untreated advanced colorectal cancer were enrolled to this single arm phase II multi-center cooperative group trial of bevacizumab combined with IFL. The first 20 patients received irinotecan (125 mg/m(2)), 5-fluorouracil (500 mg/m(2)) and leucovorin (20 mg/m(2)) weekly for four of six weeks and high-dose bevacizumab (10 mg/kg) every other week. Following a toxicity review of other trials using IFL, subsequent patients were enrolled at reduced doses of irinotecan (100 mg/m(2)) and 5-fluorouracil (400 mg/m(2)). Results: Of the 92 patients accrued to the study, toxicity data are available for 87 patients and efficacy data for 81 patients. At a median follow-up of 37.5 months, median overall survival is 26.3 months, median progression free survival is 10.7 months and 1-year survival is 85%. The overall response rate is 49.4% (6.2% complete responses). A reduction in the starting doses of irinotecan and 5-fluorouracil decreased the occurrence of vomiting, diarrhea and neutropenia related complications. Bleeding occurred in 37 patients; all events but two were grade 1 or grade 2. There were nine reports of grade 3 or grade 4 thrombo-embolic events. Hypertension of any grade occurred in 13% of patients and proteinuria was infrequent. Conclusion: High-dose bevacizumab added to IFL is a well-tolerated and highly active regimen in patients with previously untreated metastatic colorectal cancer.
