Long-term survival of esophageal squamous cell carcinoma after surgical treatment in a large-scale retrospective study from a single cancer center

Purpose To analyze the long-term overall survival(OS)and influencing factors of patients with esophageal squamous cell cancer(ESCC)under surgical treatment.Method We collected patients with ESCC who received surgical treatment in Sichuan Cancer Hospital&institute from January 2010 to December 2017,and selected 2,766 patients with thoracic esophageal carcinoma with relatively complete follow-up results as the objects of this study.We analyzed the characteristics,postoperative complications and long-term OS results of those patients.Results Of the 2766 patients,81.6%were male,midthoracic esophageal cancer accounted for 53.5%.McKeown was used in 72.0%of patients and Ivor-Lewis was used in 26.4%of patients.About 47.8%of patients received minimally invasive esophagectomy(MIE).The overall complication rate was 25.8%.The 1-year,3-year and 5-year OS rates were 86.2%,57.5%and 46.8%,respectively.McKeown had a better long-term OS rate than Ivor-Lewis(49.5%vs 41.2%,P<0.001),and MIE is superior to open surgery(51.8%vs 42.5%,P<0.001).Conclusion McKeown has advantages over Ivor-Lewis.MIE results in better long-term survival outcomes for patients.But more prospective randomized controlled trials with large samples are needed.
