Background: The role of video-assisted thoracoscopic segmentectomy in the treatment of clinical IA non-small-cell lung cancer is not well established. The aim of our retrospective analysis was to evaluate the oncological results of complex and simple video-assisted thoracoscopic segmentectomy. Methods: From 2015 to June 2020, data of n = 163 consecutive patients undergoing video-assisted thoracoscopic segmentectomy for solitary pulmonary nodule were analysed. The Kaplan–Meier method, log-rank test and Cox regression were used to estimate, compare survivals and identify risk factors of worse oncological outcomes. Results: In this period, n = 123 patients underwent video-assisted thoracoscopic segmentectomy for non-small-cell lung cancer: we performed n = 65 simple and n = 58 complex video-assisted thoracoscopic segmentectomy; n = 99 (80.5%) had a solid appearance on computed tomography scan and n = 78 (63.4%) a moderate-to-high [18F]-2-fluoro-2-deoxy-D-glucose (FDG)-positron emission tomographic computed tomography scan avidity. Mortality was 0%, and complications occurred in n = 14 (21.5%) and 9 (15.5%) patients. The median follow-up was 24 (range: 6−60) months and the 5-year overall survival was 96% without difference between video-assisted thoracoscopic segmentectomies (p = 0.16). Local recurrence developed in n = 2 (3.1%) and n = 3 (5.2%) patients; regional in n = 2 (3.1%) and 1 (1.8%) and distant in 8 (12.3%) and 2 (3.4%), without difference between video-assisted thoracoscopic segmentectomies (p = 0.51). The overall 5-year disease-free survival rate was 78%. Pathological upstaging was observed in n = 13 patients (nodal in n = 6, tumour in n = 7) and it was the only significant factor for worse disease-free survival at the multivariable analysis (hazard ratio: 2.43, 95% CI: 1.04−8.68, p = 0.049), value confirmed also in the group of intended video-assisted thoracoscopic segmentectomy (p = 0.047). Conclusions: Pathological upstaging after simple or complex video-assisted thoracoscopic segmentectomy is a risk factor for recurrence and then video-assisted thoracoscopic segmentectomy should be considered an appropriate therapeutic option for selected stage IA non-small-cell lung cancer patients.

Abstract
Background: The role of video-assisted thoracoscopic segmentectomy in the treatment of clinical IA non-small-cell lung cancer is not well established. The aim of our retrospective analysis was to evaluate the oncological results of complex and simple video-assisted thoracoscopic segmentectomy. Methods: From 2015 to June 2020, data of n = 163 consecutive patients undergoing video-assisted thoracoscopic segmentectomy for solitary pulmonary nodule were analysed. The Kaplan–Meier method, log-rank test and Cox regression were used to estimate, compare survivals and identify risk factors of worse oncological outcomes. Results: In this period, n = 123 patients underwent video-assisted thoracoscopic segmentectomy for non-small-cell lung cancer: we performed n = 65 simple and n = 58 complex video-assisted thoracoscopic segmentectomy; n = 99 (80.5%) had a solid appearance on computed tomography scan and n = 78 (63.4%) a moderate-to-high [18F]-2-fluoro-2-deoxy-D-glucose (FDG)-positron emission tomographic computed tomography scan avidity. Mortality was 0%, and complications occurred in n = 14 (21.5%) and 9 (15.5%) patients. The median follow-up was 24 (range: 6−60) months and the 5-year overall survival was 96% without difference between video-assisted thoracoscopic segmentectomies (p = 0.16).
