Objective: To examine the role of radical segmentectomy, defined as a segmentectomy with extensive hilar/mediastinal lymph node dissection and a sufficient surgical margin, for local control in cT1 N0 M0/pN1-2 non-small cell lung cancer (NSCLC), we examined the following: (1) whether metastases were observed in specimens additionally resected by completion lobectomy undertaken after segmentectomy because of pN1-2 disease and (2) prognostic outcome in patients whose operations were completed with segmentectomy regardless of pN1-2. Methods: Of 275 patients with cT1 N0 M0 NSCLC who were scheduled to undergo radical segmentectomy, 15 (6%) had a diagnosis of pN1 or N2 disease. Of these patients, 10 were additionally treated with completion lobectomy, whereas the operations of the remaining 5 were completed with segmentectomy. Results: None of the 10 patients who underwent completion lobectomy showed residual metastases in the specimens additionally resected by completion lobectomy. Two of the 5 patients whose operations were completed with segmentectomy, regardless of N1 or N2 disease, had tumor recurrence, but their first recurrence was not local. Conclusions: Radical segmentectomy, with extensive hilar/mediastinal lymph node dissection and a sufficient surgical margin, may play a role in local control in patients with cT1 N0 M0/pN1-2 NSCLC.
