    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.
