Abstract
7615 Background: To compare docetaxel versus vinorelbine as front-line treatment of elderly patients with advanced non-small-cell lung cancer (NSCLC). Methods: Chemotherapy-naive patients >65 years, with stage histologically or cytologically documented IIIB/IV NSCLC and performance status (PS) 0–3 were randomly assigned to receive docetaxel 38 mg/m2 (days 1 and 8) or vinorelbine 25 mg/m2 (days 1 and 8) every 21 days. Treatment was continued for a maximum of six cycles and was interrupted in case of disease progression or unacceptable toxicity. Results: A total of 112 patients with median age of 76 years (range, 66–87) were enrolled onto the study. PS 2–3 had 39 (35%) patients. The two treatment groups were well balanced. There was no statistical difference between the 2 arms in median overall survival (6.27 months vs 3.97 months; p=0.129), in median time to progression (2.2 months vs 2 months; p=0.863.) and in overall response rate (5.3% vs 11.3%; p=0.247). Docetaxel conferred a statistically significant survival benefit compared to vinorelbine only in patients with PS 0–1 (11.4 months vs 4.3 months; p=0.009). Among patients treated with docetaxel there was a significant difference in median overall survival for patients with PS 0–1 compared with patients with PS 2–3 (11.4 months vs 2.5 months; p=0.004) while there was no statistical difference in the vinorelbine arm (4.3 months vs 2.8 months; p=0.970).The most common grade 3 and 4 toxicity was neutropenia (3.4% for docetaxel; 27.8% for vinorelbine; p=0.0001). Other toxicities were mild, well tolerated and similar for both groups with the exception of asthenia grade 2 (8.6% for docetaxel; 24.1% for vinorelbine; p=0.026). Conclusions: Docetaxel improves survival compared with vinorelbine in elderly patients with advanced non-small-cell lung cancer and good performance status without increasing toxicity. No significant financial relationships to disclose.
