PS01.197: SURVIVAL COMPARISON BETWEEN IVOR-LEWIS AND MCKEOWN MINIMALLY INVASIVE ESOPHAGECTOMY FOR ESOPHAGEAL CANCER: A PROSPECTIVE RANDOMIZED STUDY
Abstract Background Both Ivor Lewis (anastomosis in the chest) and McKeown (anastomosis in the neck) esophagectomy has been used to treat patients with esophageal cancer. It is unclear in literature about the survival difference performed by these two methods. Methods A prospective randomized trial enrolling 100 patients with esophageal cancer in the middle or lower esophagus was done to compare the survival outcome treated with minimally invasive esophagectomy by Ivor Lewis and McKeown approaches. Analysis for the retrospective patient cohort (n = 253) including Ivor Lewis (n = 115) and McKeown (n = 138) MIE in the same hospital was also performed. Results There is no significant difference in the overall and disease progression-free survival duration between the two groups of patients (n = 50 for each group) (Figure 1 for overall survival). Similar results were found when the comparison was done for the retrospective and whole patients cohort. Multivariate analysis demonstrates the TNM staging of the tumor to be the single significant factor for prognosis in terms of overall and disease progression-free survival. There was no significant difference in overall and disease progression- free survival between the patients with Ivor Lewis and McKeown MIE both in prospective and retrospective study cohort. Conclusion Ivor Lewis and McKeown MIE provide a similar survival results for the patients with esophageal cancer in the middle and lower thoracic esophagus.
