Résumé
In this phase II study, gemcitabine and vinorelbine were combined at suboptimal doses for weekly administration in advanced non-small cell lung cancer (NSCLC). The primary objectives were to determine objective response rate (ORR) and time to progression (TTP). Secondary endpoints were safety and overall survival. Chemonaive patients with histologically or cytologically confirmed stage IIIB or IV NSCLC received vinorelbine (25 mg/m2) immediately followed by gemcitabine (800 mg/m2) once each week (on day 1) for 6 months without rest. From May 1998 to May 1999, 40 patients were enrolled (85% males; 70% stage IV) with a median age of 65.5. A total of 478 doses were administered, with a median of 9 per patient (range 2-72). The ORR was 27.5% (95% CI, 15.1-44.1%). The median TTP was 3.5 months (95% CI, 2.9-4.4 months). At a median follow-up of 6.5 months, the median survival was 11.6 months, and survival rates at 1 and 2 year(s) were 47.5% and 15.8%, respectively. The most common grade 3/4 hematologic toxicity was neutropenia, in 70% of patients, with febrile neutropenia in 28%. The most common grade 3/4 non-hematologic toxicity was transaminase elevation, in 22.5% of patients, which was transient and reversible. The other most prominent toxicities were, unexpectedly, pulmonary and cardiac toxicities. Based on these results, weekly, long-term administration of gemcitabine-vinorelbine appears to be an active regimen in NSCLC that warrants further investigation.
