Gemcitabine plus vinorelbine versus vinorelbine alone in elderly patients with advanced non-small-cell lung cancer

PURPOSE: To evaluate whether the addition of gemcitabine (G) to vinorelbine (V) improves survival and quality of life (QoL) among elderly patients with advanced non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS: Patients with NSCLC aged >/= 70 years with advanced disease were randomly allocated to receive V 30 mg/m(2) on days 1 and 8 every 3 weeks or G 1,200 mg/m(2) + V 30 mg/m(2) on days 1 and 8 every 3 weeks. The estimated sample size was 120 patients per arm, but an interim analysis of survival was planned based on the first 60 patients per arm. RESULTS: In May 1999, the survival data were analyzed of 120 eligible patients (V group = 60; G + V group = 60) who had been randomized from June 1997 to February 1999. Forty-nine patients had stage IIIB disease, and 71 had stage IV. At a median potential follow-up of 14 months (range, 3 to 22 months), 93 patients had died (G + V group = 41; V group = 52). In the G + V group, median survival time was 29 weeks and projected 1-year survival was 30%; these values were 18 weeks and 13% in the V group. According to multivariate Cox analysis, the risk of death in the G + V arm compared with the V arm was 0.48 (95% confidence interval, 0. 29 to 0.79; P <.01). Combination therapy was also associated with a clear delay in symptom and QoL deterioration. The overall response rates were 22% and 15% in the G + V and V groups, respectively. CONCLUSION: In elderly patients with NSCLC, G + V treatment is associated with significantly better survival than is V alone.
