Phase II trial of gemcitabine in advanced non-small-cell lung cancer.

: Gemcitabine has shown activity in different solid tumors. In the present study we have evaluated its efficacy in 32 patients with advanced non-small-cell lung cancer in a phase II trial. Gemcitabine (1250 mg/m2) was given intravenously as a 30-minute infusion on days 1, 8 and 15. Cycles were repeated every 4 weeks. Twenty-nine patients were evaluable for response and all patients for toxicity. Partial remissions and stable disease were seen in 4 (14%) and 13 (45%) patients, respectively. Improvement of symptoms occurred in 54% of the patients. Side effects were mild and included predominantly leukopenia and thrombocytopenia. In conclusion, gemcitabine is active and well tolerated in patients with advanced non-small-cell lung cancer.
