title: [Combined chemotherapy with domestic gemcitabine plus carboplatin in the treatment of advanced non-small cell lung cancer].
abstract: BACKGROUND
  Chemotherapy is very important in the treatment of advanced non-small cell lung cancer (NSCLC). The aim of this study is to evaluate the efficacy, clinical benefit and toxicity of combined chemotherapy with domestic gemcitabine (ZEFEI) plus carboplatin in the treatment of advanced NSCLC.
  
  
  METHODS
  Thirty-four previously untreated patients with advanced NSCLC (stage III-IV) received domestic gemcitabine of 1000mg/m² on days 1, 8, and carboplatin of AUC 5 on day 1, with 21 days as a cycle. Each patient received at least three cycles.
  
  
  RESULTS
  The total clinical response rate (complete and partial response) was 44% (15/34). Overall clinical benefit rate was 53% (18/34). The main toxicities were hematological toxicities. The rate of grade III-IV leukopenia and thrombocytopenia was 47% and 24% respectively.
  
  
  CONCLUSIONS
  Combined chemotherapy with domestic gemcitabine plus carboplatin is an effective and feasible regimen for advanced NSCLC.
