Esophageal Tumor Length – An Underestimated Predictor of Survival After Esophageal Cancer Resection

Abstract Introduction. Esophageal cancer is one of the most aggressive visceral tumors with increasing frequency and poor prognosis. Differences in survival between patients same clinical tumor stage necessitate searching for additional prognostic markers to help identify at high risk recurrence, metastasis or death. The aim study was assess significance length on after esophageal resection operated a center surgery. Materials methods. This prospective cohort including 117 who had undergone surgical curative intent cancer. conducted First Surgical Clinic UMHATEM “N. I. Pirogov”, Sofia, Bulgaria. inclusion period 1st January 2013 31st December 2015 were followed – up until 10 April 2022. divided into two groups according under 3 cm (group 1) over 2). impact analyzed Cox regression analysis. Overall presented by Kaplan-Meier method log-rank tests. Results. 5-year rate 11.1%. Median 26.0 months (95% CI 18.3-33.7 months) first group 13.0 10.3-15.7 second patients. Tumor negative factor (HR 2.36 95% 1.06-5.25; p = 0,03). Conclusion. Length powerful independent predictor addition TNM stage.
