Mitomycin C and UFT/leucovorin as salvage treatment in patients with advanced colorectal cancer.

概要
OBJECTIVE
The purpose of this study was to determine the efficacy and toxicity of uracil/tegafur (UFT) plus oral leucovorin (LV) and mitomycin C as salvage chemotherapy for heavily pretreated patients with metastatic colorectal cancer.
METHODS
A total of 44 patients were treated with i.v. mitomycin C (6 mg/m(2) on day 1) and oral UFT (350 mg/m(2)) plus LV (90 mg), both divided in 3 daily doses from day 1 to day 14 every 3 weeks. All patients had failed prior first-line and second- line treatment with oxaliplatin, bevacizumab, irinotecan, cetuximab and 5-fluorouracil (5-FU). Forty -three patients were evaluable for the response.
RESULTS
The overall response rate (intent-to-treat) was 9.3% and disease stabilization was achieved in 25.7% of the patients. Median time to progression (TTP) was 5 months (range 2-13) and median overall survival (OS) 7.5 months (range 4-16). Fatigue and myelosuppression were the most frequent side effects. The most common nonhematological toxicities consisted of mild and reversible nausea and diarrhea. Severe symptoms were only occasionally seen.
CONCLUSIONS
These data show that the combination of mitomycin C/UFT/LV provides an acceptable and safe therapeutic option in extensively pretreated metastatic colorectal cancer.
