Preoperative Chemotherapy Versus Preoperative Chemoradiotherapy for Stage III (N2) Non–Small-Cell Lung Cancer: "Purpose: To compare preoperative chemotherapy (ChT) and preoperative chemoradiotherapy (ChT-RT) in operable Stage III non–small-cell lung cancer.Methods and Materials: This retrospective study analyzed all patients with pathologically confirmed Stage III (N2) non–small-cell lung cancer who initiated preoperative ChT or ChT-RT at Duke University between 1995 and 2006. Mediastinal pathologic complete response (pCR) rates were compared using a chi-square test. The actuarial overall survival, disease-free survival, and local control were estimated using the Kaplan-Meier method and compared using the log–rank test. Multivariate Cox regression analysis was also performed.Results: A total of 101 patients who initiated preoperative therapy with planned resection were identified. The median follow-up was 20 months for all patients and 38 months for survivors. The mediastinal lymph nodes were reassessed after preoperative therapy in 88 patients (87%). Within this group, a mediastinal pCR was achieved in 35% after preoperative ChT vs. 65% after preoperative ChT-RT (p = 0.01). Resection was performed in 69% after ChT and 84% after ChT-RT (p = 0.1). For all patients, the overall survival, disease-free survival, and local control rate at 3 years was 40%, 27%, and 66%, respectively. No statistically significant differences were found in the clinical endpoints between the ChT and ChT-RT subgroups. On multivariate analysis, a mediastinal pCR was associated with improved disease-free survival (p = 0.03) and local control (p = 0.03), but not overall survival (p = 0.86).Conclusion: Preoperative ChT-RT was associated with higher mediastinal pCR rates but not improved survival."
