BACKGROUND: This study sought to ascertain whether induction-concurrent radiotherapy added to chemotherapy could improve the survival of patients undergoing surgery for stage IIIA N2 nonsmall cell lung cancer (NSCLC). METHODS:Patients with pathologically proven N2 disease were randomized to receive either induction chemotherapy (docetaxel 60 mg/m(2) and carboplatin AUC [area under the receiver operating characteristic curve] = 5 for 2 cycles) plus concurrent radiation therapy (40 Gy) followed by surgery (CRS arm) or induction chemotherapy followed by surgery (CS arm). They subsequently underwent pulmonary resection when possible. RESULTS:Sixty patients were randomly assigned between December 2000 and August 2005. The study was prematurely terminated in January 2006 because of slow accrual. The most common toxicity was grade 3 or 4 leukopenia in 92.9% of patients in the CRS arm and 46.4% in the CS arm. Induction therapy was generally well tolerated, and there were no treatment-related deaths in either arm. Downstaging in the CS arm and CRS arm was 21% and 40%, respectively. The progression-free survival (PFS) and overall survival (OS) in the CS arm were 9.7 months and 29.9 months (PFS, hazard ratio [HR] = 0.68, P = .187), and those in the CRS arm were 12.4 months and 39.6 months (OS, HR = 0.77, P = .397), respectively. The PFS with and without downstaging was 55.0 and 9.4 months, respectively (HR = 3.39, P = .001). The OS with and without downstaging was 63.3 and 29.5 months, respectively (HR = 2.62, P = .021). CONCLUSIONS: The addition of radiotherapy to induction chemotherapy conferred better local control without significant adverse events. Tumor downstaging is important for prolonging the OS in patients with stage IIIA (N2) NSCLC.
