Efficacy, toxicity and cost analysis for non-platinum triplet (gemcitabine and vinorelbine, followed by docetaxel) vs. platinum-based chemotherapy in IIIB/IV non-small-cell lung cancer: single-institution experience.

A new non-platinum sequential triplet combination chemotherapy regimen, comprising gemcitabine (1000 mg/m(2)) and vinorelbine (25 mg/m(2)), followed by docetaxel (60 mg/m(2)), was compared in terms of efficacy, toxicity and cost with platinum-based chemotherapy regimens (comprising cisplatin plus one or more other anti-tumour drugs) for the treatment of advanced non-small-cell lung cancer in a matched, small-sample size, case-control study. Patients were selected from a single institution. Patients in the platinum and non-platinum groups were matched for clinical stage (IIIB/IV), performance status (0/1), age and sex. For the non-platinum and platinum groups, the overall response rates were 40% and 47%, and the median survival times were 14 and 14.5 months respectively. The most common grade 3-4 toxicity was neutropenia (27%) in the non-platinum group and nausea/vomiting (67%) in the platinum group. The total treatment cost did not differ significantly between the two groups. The non-platinum sequential triplet combination chemotherapy regimen studied was shown to be as effective as the traditional cisplatin-based combination chemotherapy regimen, and was associated with less toxicity.
