A phase-ii trial of 5-Fluorouracil, folinic Acid, vinorelbine in pretreated patients with metastic colorectal-cancer.

43 patients with metastatic colorectal Cancer pretreated with 5-fluorouracil-based chemotherapy received vinorelbine plus 5-fluorouracil plus folinic acid with the aim of evaluating vinorelbine activity in advanced colorectal cancer and its potential synergism with commonly used drugs. 9 partial responses were observed, for an;overall objective response rate of 20.9%. 20 additional patients had stable disease (46.5%). Median duration of response was 7 months. Median survival from the start of treatment was 6 months. The main toxic effect was myelosuppression. We conclude that our regimen is active enough to warrant further evaluation in advanced colorectal cancer.
