Background: Body weight loss (BWL) is frequently observed in gastric cancer patients who undergo gastrectomy for gastric cancer. The risk factors for severe BWL after gastrectomy remain unclear. Methods: The present study retrospectively examined patients who underwent curative gastrectomy for gastric cancer between January 2012 and June 2014 at Kanagawa Cancer Center. All patients received perioperative care based on the enhanced recovery after surgery protocol. The %BWL value was calculated based on the percentage of body weight at 1 month after surgery in comparison to the preoperative body weight. Severe BWL was defined as %BWL > 10%. The risk factors for severe BWL were determined by both univariate and multivariate logistic regression analyses. Results: There were 278 patients examined. The median age of the patients was 68 years. The operative procedures included total gastrectomy [n=97; open (n=61) and laparoscopic {n=36)] and distal gastrectomy (n=181). Surgical complications of grade >= 2 (as defined by the Clavien-Dindo classification) were observed in 37 patients, these included: pancreatic fistula (n=9), anastomotic leakage (n=5), and abdominal abscess (n=3). There were no cases of surgery-associated mortality. Both univariate and multivariate logistic analyses demonstrated that surgical complications, and total gastrectomy were significant risk factors for severe BWL. Conclusions: Surgical complications and total gastrectomy were identified as being significant risk factors for severe BWL in the 1st month after gastrectomy. To maintain body weight after gastrectomy, physicians should pay careful attention to patients who undergo total gastrectomy and those who develop surgical complications.
