title: Weekly docetaxel with either gemcitabine or vinorelbine as second-line treatment in patients with advanced nonsmall cell lung carcinoma: Phase II trials of the Minnie Pearl Cancer Research Network.
abstract: BACKGROUND
  The current study was conducted to evaluate the feasibility, toxicity, and efficacy of weekly docetaxel when paired with either gemcitabine or vinorelbine as the second-line treatment of patients with advanced nonsmall cell lung carcinoma.
  
  
  METHODS
  Patients with progressive nonsmall cell lung carcinoma after one previous chemotherapeutic regimen, an Eastern Cooperative Oncology Group performance status of 0-2, and measurable lesions were eligible for treatment in these Phase II trials. Patients who had not received gemcitabine previously were treated with docetaxel, 30 mg/m(2), and gemcitabine, 800 mg/m(2), both of which were administered intravenously (i.v.) on Days 1, 8, and 15 of a 28-day cycle. If the patients had received gemcitabine as part of first-line therapy, they were treated with docetaxel, 30 mg/m(2), and vinorelbine, 20 mg/m(2) i.v., on Days 1, 8, and 15 of a 28-day cycle. Patients were reevaluated after two courses of treatment, and responding patients continued treatment for six courses or until disease progression.
  
  
  RESULTS
  Forty patients were treated with a combination of docetaxel and gemcitabine, and 23 patients received docetaxel and vinorelbine. The docetaxel/gemcitabine combination was reasonably well tolerated, with moderate myelosuppression and a few nonhematologic toxicities reported. The objective response rate was 10%, with a 1-year survival rate of 20%. The docetaxel/vinorelbine combination was found to be poorly tolerated, with Grade 3/4 leukopenia reported in 71% of patients and neutropenic fever reported in 70% of patients despite frequent dose reductions and omission of the Day 15 doses. Enrollment onto this regimen was stopped prematurely due to toxicity, and after no major responses were observed in the first 20 evaluable patients.
  
  
  CONCLUSIONS
  The combination of weekly docetaxel/gemcitabine appears to be feasible and relatively well tolerated as second-line treatment in patients with advanced nonsmall cell lung carcinoma, whereas a weekly combination of docetaxel and vinorelbine did not appear to be tolerable at the doses and schedule used in the current study. Neither regimen showed a level of activity that suggested any advantage compared with the results obtained with single-agent docetaxel in this setting.
