Review Meta Analysis
[Gemcitabine in the first line therapy of advanced and metastatic non-small-cell lung carcinoma (NSCLC): review of the results of phase III studies].
Modern platinum-based combination therapies containing gemcitabine, vinorelbine or taxanes produce response rates of 30-40%, median survival times of 8-10 months and 1-year survival rates of approximately 35% in patients with advanced non-small-cell lung cancer (NSCLC). Of the new drugs available, gemcitabine (Gemzar, Lilly, Bad Homburg, Germany) has been the most extensively researched in clinical trials and exhibits a consistent database. A total of 37 randomized phase III trials involving more than 15,000 patients have been published to evaluate gemcitabine as first-line therapy for treating locally advanced and/or metastatic NSCLC. ⋯ In contrast, platinum based 3-agent schedules do not offer any survival benefit. In elderly patients with poor performance status single agent treatment with a modern cytotoxic agent should be considered. Furthermore, according to the experiences from phase III studies so far, platinum- free combinations open up the possibility of a more feasible and clinically practical, active and well tolerated treatment which is associated with a positive impact on patient quality of life.
