UFT Plus Cisplatin With Concurrent Radiotherapy for Locally Advanced Non–Small-Cell Lung Cancer

ABSTRACT: A phase II study of combined-modality treatment consisting of uracil and tegafur (in a molar ratio of 4:1 [UFT]) plus cisplatin (Platinol) and concurrent radiotherapy was conducted to evaluate the activity of this regimen in patients with locally advanced non–small-cell lung cancer. Eligible patients with cytologically or histologically confirmed, unresectable stage III non–small-cell lung cancer received UFT (400 mg/m² orally on days 1 through 52) and cisplatin (80 mg/m² intravenously on days 8, 29, and 50). Radiotherapy, with a total dose of 60.8 Gy, was delivered in 38 fractions on days 1 through 52. Among the 17 patients entered, 16 experienced partial responses (94%; 95% confidence interval, 83% to 100%). The median time to tumor progression was 30 weeks (range, 8 to 87 weeks), and the 1-year survival rate was 80%. Hematologic toxicity was moderate. Grade 3 leukopenia occurred in 10 patients (59%), but no grade 4 hematologic toxicity was observed. No grades 3 or 4 nonhematologic toxicities were reported. These observations suggest that oral UFT plus cisplatin with concurrent radiotherapy can be safely administered to patients with locally advanced non–small-cell lung cancer. The demonstrated antitumor activity is high, making this combined-modality treatment worthy of further investigation in a multi-institution trial. [ONCOLOGY 7(Suppl 3):98-101, 1999]
