[High BMI does not influence short- and long-term outcomes of patients with esophageal cancer treated with esophagectomy].
The aim of this study was to clarify the influence of a high body mass index (BMI) on short- and long-term outcomes of patients after esophagectomy for cancer.


METHODS
A total of 164 patients with a BM ≥ 18.5 who underwent esophagectomy for cancer from July 2008 through March 2013 were enrolled. Patients were divided into 2 groups according to BMI: BMI<5 (normal BMI group) and BM ≥ 25 (high BMI group). Further, the short- and long-term outcomes after esophagectomy were retrospectively analyzed.


RESULTS
The median BMI was 21.6. The high BMI group (n=26) had significantly more histological adenocarcinomas than the normal BMI group (p=0.003). Other clinicopathological factors such as the type of surgery performed, R0 resections, and perioperative complications, were not influenced by the BMI. There were no significant differences between the 2 groups in the 3-year disease-free rates and 3-year overall survival rates.


CONCLUSIONS
Esophagectomy for patients with a high BMI is acceptable based on the similar short- and long-term outcomes when compared with normal BMI patients.
