BackgroundPulmonary large-cell neuroendocrine carcinoma (LCNEC) is a rare subtype of lung cancer with dismal prognosis. Long-term outcomes after primarily video-assisted thoracoscopic surgery (VATS) have not yet been described in LCNEC. This study aims to determine overall survival and recurrence-free survival after VATS as well as to identify prognostic factors for survival and recurrence. MethodsData were obtained from a prospective institutional database. Kaplan-Meier estimates of overall survival and recurrence-free survival were determined and compared across prognostic factors using log-rank analysis and the Cox proportional hazards model. ResultsData from 82 consecutive patients undergoing surgical resection from 2009 to 2020 were included. All patients underwent surgical resection with curative intent, of whom 96.3% were by a VATS approach. Morbidity was low without any conversions or 30-day mortality. Lobectomy was performed in 87.8% of patients, followed by wedge resection in 4.9% and segmentectomy in 3.7%. No pneumonectomies were performed. Radical resection (R0) was achieved in 97.6%. Thirty-four patients (41.5%) had adjuvant platinum-based chemotherapy and high proportion completed at least four series (76.7%). The mean follow-up was 5.1 years. The 1-year, 3-year, and 5-year overall survival rates were 86%, 54%, and 45%, while the corresponding recurrence-free survival rates were 67%, 45%, and 35%. Advanced age was an independent predictor of poor overall survival (HR 2.08; 95% CI 1.04–4.17; p = 0.038). ConclusionA 96.3% VATS rate was feasible in LCNEC and associated with a low morbidity rate and a high compliance with adjuvant chemotherapy. Overall survival and recurrence-free survival was comparable to previous series using thoracotomy.
