Objective:To evaluate the efficacy and toxicity of docetaxel and vinorelbine as second-line chemotherapy in the treatment of advanced non-small cell lung cancer (NSCLC).Methods:48 histologically or cytologically confirmed NSCLC patients with progressive or recurrent disease after first-line treatment were treated with docetaxel and vinorelbine.The chemotherapy included vinorelbine (25 mg/m2) on days 1,5 and docetaxel (60 mg/m2) on day 1.The treatment was repeated every 3 weeks.Patients receiving at least two cycles were evaluated for efficacy and toxicity.Results:Of 48 patients,1 patient achieved complete response and 16 achieved partial response.Overall response rate for all 48 patients was 35.4% (17/48).Main hematologic toxicities included neutropenia (60.4%) and febrile neutropenia (29.2%) and non-hematologic toxicities were mild.Conclusion:The combination of docetaxel-vinorelbine as second-line chemotherapy is an effective regimen with manageable toxicity for the treatment of advanced NSCLC.Further studies may confirm these results.
