BackgroundThe survival outcomes of patients with esophageal squamous cell carcinoma (ESCC) after open or thoracoscopic upfront esophagectomy remained unclear.ObjectiveThe aim of this retrospective study was to compare overall survival between open and thoracoscopic esophagectomy for ESCC patients without neoadjuvant chemodatiotherapy (CRT).MethodsThe Taiwan Cancer Registry was investigated for ESCC cases from 2008 to 2016. We enrolled 2053 ESCC patients receiving open (n = 645) or thoracoscopic (n = 1408) upfront esophagectomy. One-to-two propensity score matching between the two groups was performed. Stage-specific survival was compared before and after propensity score matching. Univariate analysis and multivariate analysis were used to identify risk factors.ResultsAfter one-to-two propensity score matching, a total of 1299 ESCC patients with comparable clinic-pathologic features were identified. There were 433 patients in the open group and 866 patients in the thoracoscopic group. The 3-year overall survival of matched patients in the thoracoscopic group was better than that of matched patients in the open group (58.58% vs 47.62%, P = 0.0002). Stage-specific comparisons showed thoracoscopic esophagectomy is associated with better survival than open esophagectomy in patients with pathologic I/II ESCC. In multivariate analysis, surgical approach was still an independent prognostic factor before and after one-to-two propensity score matching.ConclusionThis propensity-matched study revealed that thoracoscopic esophagectomy could provide better survival than open esophagectomy in ESCC patients without neoadjuvant CRT.Copyright © 2021 The Author(s).
