Purpose: Non-small cell lung cancers (NSCLCs) with pathologically documented ipsilateral mediastinal lymph node (LN) metastases (pN2) are a broad spectrum of diseases. We retrospectively analyzed prognostic factors for cases of pN2 NSCLC treated by surgical resection. Methods: Clinicopathological data were reviewed for consecutive 121 patients who underwent anatomical pulmonary resection with mediastinal LN sampling or dissection for pN2 NSCLC over a 15-year period. Results: The 5-year survival rate for all patients was 29.9%. Clinical N status, curability, surgical procedure and adjuvant chemotherapy were favorable prognostic factors in uni-variate analysis, with 5-year survival rates of 35.0% for cN0/1 vs. 17.7% for cN2/3 cases; 33.1% for R0 vs. 14.7% for R1/2 resection; 31.5% for lobectomy vs. 25.0% for bilobectomy and 15.6% for pneumonectomy; and 72.7% with adjuvant chemotherapy vs. 23.8% without adjuvant chemotherapy. Survival did not differ significantly based on gender, age, smoking status, clinical T status, tumor location, histology, skip metastasis, subcarinal LN metastasis, or number of involved N2 levels. In multivariate analysis, adjuvant chemotherapy, R0 resection, and lobectomy emerged as independent favorable prognostic factors. Conclusion: Complete resection using lobectomy and adjuvant chemotherapy are favorable prognostic factors in cases of pN2 NSCLC.
