Salvage surgery for local recurrence after sublobar surgery in Stages I and IInon-small cell lung cancer.

Abstract

To examine if patients undergoing salvage surgery for local recurrence following sublobar resection (SLR) have similar perioperative complications and overall survival (OS) compared to lobectomy patients for early stage non-small cell lung cancer (NSCLC). Patients undergoing lobectomy and SLR (segmentectomy or wedge resection) for Stages I andII NSCLC from 2010 to 2016 were reviewed. Lobectomy patients and those who underwent salvage surgery for local recurrence after SLR were compared. Salvage surgeries were curative-intent resections for recurrence. Cases included 634 lobectomies and 986 SLR. Fifty-nine SLR patients (6.0%) recurred at a local site compared to 11 lobectomy patients (1.7%; p < 0.001). Twenty-three locally recurrent SLR patients (39.0%) went on to salvage surgery. Peri-operative complications after salvage surgeries were similar to lobectomies (34.8% 8/23 vs. 34.7% 220/634, p = 1.00). OS at 5 years for salvage surgery patients was similar to lobectomy patients (79.6% 13/23 vs. 70.6% 227/634, p = 0.23). OS for patients who underwent salvage surgery was significantly better than those who did not have salvage surgery for recurrence (79.6% vs. 53.0%, p = 0.02). Patients who undergo salvage surgery for local recurrence after SLR had similar perioperative complications and OS compared to lobectomy patients but less than half underwent salvage surgery.
