Objective: The objectives of the present study were to assess the efficacy and tolerability of perioperative paclitaxel/platinum-based chemotherapy and surgery in patients with stage IIIA clinical N2 (cN2) non-small cell lung cancer (NSCLC).
Methods: Clinical N2 was defined as either >15 mm or >10 mm and multiple nodes on computed tomography (CT) scan. Thirty-four chemotherapy-naïve patients with stage IIIA cN2 received preoperative paclitaxel/cisplatin for two cycles and then underwent surgery. The treatment with paclitaxel/carboplatin was repeated for three cycles after the operation.
Results: Of the 34 patients, none achieved a complete response (CR) and 22 achieved a partial response (PR), resulting in a response rate of 65%. Among 29 patients (85%) who had received thoracotomy, 25 (74%) underwent complete resection. Two pathological CRs were observed and mediastinal nodes were free of tumor in 21%. Grade 34 toxicity was uncommon and treatment-related mortality was not observed. The median time to progression (TTP) was 12.1 months [95% confidence interval (CI) 8.315.9 months] and median overall survival (OS) was 23.6 months (95% CI 17.730.2 months).
Conclusions: Paclitaxel/platinum-based perioperative chemotherapy and surgery for patients with stage IIIA cN2 NSCLC is effective and well tolerated.
