ABSTRACT
BACKGROUND: In the present study, 3 cytotoxic agents were combined as front-line chemotherapy in advanced non-small cell lung cancer (NSCLC) patients. All 3 drugs have been used in other 2-agent combinations and have been shown to be effective as first-line therapy. PATIENTS AND METHODS: Sixty-one (53 male, 8 female, median age 65 years old) out of 67 patients were evaluable for response and toxicity. Eighty percent of the patients were stage IIIB and IV and 20% were inoperable stage IIIA. In order to obviate toxicity as much as possible, paclitaxel 135 mg/m2 was combined with gemcitabine 1000 mg/m2 for the first cycle, and 2 weeks later with vinorelbine 25 mg/m2, for the second cycle; this alternate schedule was repeated every 2 weeks for 9 cycles. RESULTS: No complete responses were observed; there was a 37.7% partial response rate and stable disease in 31.1% of the patients. The median survival was 13 months and 1-year survival, 53%. Myelotoxicity involved grade 3 neutropenia in 3.3% of the patients and grade 4 in 1.6%. CONCLUSION: Adverse reactions were few in this alternate administration of paclitaxel-gemcitabine and paclitaxel-vinorelbine in NSCLC patients; in more than half of the patients there was long median and 1-year survival.
