The authors reviewed 301 consecutive esophageal cancer patients who underwent surgery but received no adjunctive therapy. Patients were segregated into 2 subgroups by baseline body mass index (BMI): normal/low (<25 kg/m2) and overweight (≥25 kg/m2). In the high BMI group, there were more men (P < .001), fewer upper esophageal tumors (P = .021), lower baseline clinical stage (P = .006), and frequent esophageal adenocarcinoma (P < .001). Postoperative morbidity was similar in both groups with the exception of gastrointestinal complications (P = .016). The 5-year overall survival (OS) rates were 44% in the normal/low BMI group and 60% in the high BMI group (P = .017). High BMI is common in patients with esophageal cancer and the better OS/disease-free survival rates noted in patients with a high BMI is because of the diagnosis of low baseline clinical stage. Confirmation of these findings is warranted.
