Risk factors for severe weight loss after gastrectomy for gastric cancer.
2015
38 Background: Body weight loss (BWL) is frequently observed in gastric cancer patients who underwent gastrectomy for gastric cancer. Recently, we reported that severe BWL after gastrectomy was a significant risk factor for continuation of S-1 adjuvant chemotherapy. However, risk factors of BWL after surgery remain unclear. Methods: The present study retrospectively examined the patients who electively underwent curative gastrectomy for gastric cancer between January of 2012 and June of 2014. All patients received peri-operative care of ERAS protocol. %BWL was calculated by percentile of body weight at one month after surgery to preoperative body weight. Severe BWL was defined as %BWL over 10%. Risk factors for severe BWL were determined by both univariate and multivariate logistic regression analyses. Results: Two-hundred seventy eight patients were examined. Median age (range) was 68 years (27-86). Median body mass index (range) was 22 (13.4-33.5). Thirty patients had received neoadjuvant chemotherapy. ...
