Phase II study of oral fluoropyrimidine (UFT) plus vinorelbine in the elderly (age > 70) with advanced non-small cell lung cancer
18075 Background: Many pts with non-small cell lung cancer (NSCLC) are in elderly population. There are few pts who can receive standard treatment with platinum-based chemotherapy because of their poor organ functions. Thus, the development of a low-toxic and highly- effective regimen is needed for these populations. We have reported schedule-dependent synergism of vinorelbine and 5-FU against NSCLC cell lines. Furthermore, we have already conducted phase I study using vinorelbine and UFT, and have decided the recommended dose of this regimen. Methods: The objective of this prospective phase II study was to assess the efficacy and toxicity of this regimen in the elderly. Chemonaive NSCLC stage IIIB or IV pts, aged 70 or more, with performance status 0/1 were enrolled in this study. The pts received a treatment consisting of 20mg/m2 of vinorelbine on days 1 and 8, followed by 600mg of UFT orally on days 2–6 and 9–13 every 3 weeks for more than 4 cycles. Results: Until April 24, 2006, of 30 pts enrolled in this study, 29 pts were evaluable. Median age was 78 (range 71–86) and median cycles of chemotherapy were 4 (1–32). Objective response rate was 27% (95% CI; 10–44%), median time to progression was 150 days (15–470) and median over all survival time was 270 days (77–892). Treatment-related toxicity were neutropenia G3 33%, G4 7%; febrile neutropenia G3 4%; pneumonia G3 10%. Conclusions: This data points out vinorelbine and UFT as an active and tolerable regimen in the elderly with advanced NSCLC. No significant financial relationships to disclose.
