Abstract

Objective: Preoperative weight loss might increase the risk of postoperative morbidity and mortality after esophagectomy for cancer. We hypothesized that patients with esophageal cancer with >10% weight loss during the 3 months before their diagnosis would be at an increased risk of postoperative complications, have a longer length of stay, and have worse overall survival. Methods: In the present hospital-based cohort study, all patients who had undergone surgery for esophageal cancer in 1990 to 2010 at the Erasmus University Medical Center Rotterdam were included. Weight loss was defined as "no, or limited'' (<= 10%) or "severe'' (>10%). Logistic regression analysis was used to estimate the relative risk of complications, expressed as odds ratios (ORs) with 95% confidence intervals (CIs). Hazard ratios were calculated to assess the length of hospital stay and survival. The risk estimates were adjusted for potential confounding factors. Results: Of 922 included patients, 155 (17%) had experienced severe weight loss. These patients had no increased risk of early surgical, early nonsurgical, or late surgical complications (OR, 0.83 and 95% CI, 0.54-1.24; OR, 0.90 and 95% CI, 0.63-1.30; OR, 1.14 and 95% CI, 0.79-1.66, respectively) and had no increased length of stay (hazard ratio, 1.09; 95% CI, 0.89-1.35). Preoperative weight loss was followed by increased 5-year mortality (hazard ratio, 1.34; 95% CI, 1.02-1.74). Conclusions: A > 10% preoperative weight loss was followed by decreased 5-year survival after esophageal cancer surgery but no increased risk of postoperative complications.
