ABSTRACT
PURPOSE: To evaluate early outcome and long term survival in a mixed stage population of patients undergoing upfront esophagectomy for esophageal cancer. METHODS: Retrospective analysis of the data of 92 patients who underwent esophagectomy (thoracoabdominal: 76, Ivor-lewis: 16) between 1998 and 2017. Tumors were located in gastro-esophageal junction (52), lower third (31) and middle third (9) of the esophagus. Histology was: 73 adenocarcinomas and 19 squamous cell carcinomas. The stomach was used for reconstruction in 90 patients. A neck anastomosis was performed in 7 patients. End points of the study included: mortality, morbidity and long term survival. Kaplan-Meier and Cox regression analyses were used to identify prognostic factors for survival. RESULTS: The mortality was 10.9% and 29 patients presented 49 complications. Anastomotic dehiscence occurred in 17.4% of the patients and represented the most common cause of death with mortality of 37.5%. Reoperation was necessary in 14 patients. Median survival reached 25 months with 3 and 5 year survival of 30.5% and 21% respectively. Early stage tumors, absence of nodal disease, well differentiated carcinomas and lymph node ratio ≤ 0.2 were associated with 5 year survival of 82.6%, 81.6%, 83.3% and 40.4% respectively. In multivariate analysis early stage disease (OR: 15.746, 95%CI: 4.332-58.579, p < 0.001) and lymph node ratio (OR: 1.700 95%CI: 1.051-2.752, p = 0.031) were statistically associated with long term survival. CONCLUSIONS: Our results support the role of upfront surgery as the treatment of choice in early stage esophageal carcinomas without or with low nodal involvement.
