title: A retrospective study: platinum-based induction chemotherapy combined with gemcitabine or paclitaxel for stage IIB-IIIA central non-small-cell lung cancer.
abstract: BACKGROUND
  Several encouraging phase III clinical trials have evaluated platinum-based induction chemotherapy against stage IIB-IIIA non-small-cell lung cancer (NSCLC). Chemotherapy efficacy was assessed using common regimens in this retrospective analysis.
  
  
  METHODS
  From 2007 to 2011, the clinical records of stage IIB-IIIA NSCLC patients undergoing surgery after neoadjuvant chemotherapy were reviewed. Gathered data were tested for significance and variables impacting survival were assessed by univariate and Cox regression analyses.
  
  
  RESULTS
  Overall, 84% of patients were male and 93% had central disease. Platinum-based chemotherapy protocols with gemcitabine or paclitaxel gave an overall response rate of 55% (45/82) and 6.1% pathological complete response (5/82). Clinical response was unassociated with regimen or histology, while more pneumonectomies were performed in the stable compared to partial response disease group (P =0.040). Postoperative mortality was 1.2% (1/82), and complications, unassociated with regimen or histology, were atelectasis (26.8%) and supraventricular arrhythmias (13.4%). Right-sided procedures appeared to increase the incidence of bronchopleural fistula (P =0.073). The median disease-free survival time was 18 months and median overall survival time was not reached. Disease-free survival rates at one, two, and three years were 54%, 47%, and 33%, while the overall survival rate was 73%, 69%, and 59%, respectively. Disease-free survival predictors were radiographic response and mediastinal lymphadenopathy before chemotherapy (P =0.012 and 0.002, respectively).
  
  
  CONCLUSIONS
  Two cycles of platinum-based chemotherapy with gemcitabine or paclitaxel is efficacious for patients with stage IIB-IIIA central disease. Patients achieving clinical response had improved disease-free survival times, while those with mediastinal lymphadenopathy had a higher postoperative recurrence risk.
