OBJECTIVE
To assess the toxicity and activity of bolus mitomycin C (MMC) in combination with a 24-hour continuous infusion of 5-fluorouracil (5-FU) in gastric cancer patients who had received at least one prior chemotherapy regimen.
METHODS
Patients were treated with MMC (10 mg/m(2)) on days 1 and 22, 5-FU (2.6 g/m(2)) as a 24-hour infusion, and folinic acid 500 mg/m(2) weekly for 6 weeks.
RESULTS
Thirty-four patients with gastric cancer, 16 after failure of first-line chemotherapy and 18 after failure of at least two prior chemotherapies, were included. In the intent-to-treat analysis, 9 (26.5%) of the 34 patients had a partial response and 10 (29.4%) a disease stabilization (disease control rate 56%). The median time to progression was 3.3 months (CI95: 2.8-3.7), and the median overall survival was 7.2 months (CI95: 5.9-8.4). Grade III/IV thrombocytopenia occurred in 14.7% of patients (n = 5), while the most frequent nonhematological grade III/IV toxicities were mucositis and diarrhea, each affecting 9% of patients.
CONCLUSIONS
As the tested regimen was generally safe and well tolerated by the patients, MMC plus infusional 5-FU/folinic acid may be a potential second-line regimen for patients with advanced gastric cancer.
