Background/Aims : There is a significant weight change in most gastric cancer patients during the perioperative period. We studied the influence of perioperative body weight changes on the prognosis of gastric cancer patients.
Methods : Eight hundred and forty-nine patients with gastric cancer underwent surgery between 1991 and 1995. Among them, 449 patient have lived for more than 5 years (survived group) and 400 died within 5 years, postoperatively (deceased group). We compared the perioperative body weight changes and prognosis of patients between the two groups.
Results : Preoperative weight loss of the survived group was less than that of the deceased group (p〈0.001). In patients who underwent curative surgery, preoperative relative body weight of the survived group was 104.0±13.8％ and that of the deceased group was 100.8±14.3％ (p=0.001). After curative surgery, five-year survival rate of the patients whose preoperative relative body weight was above 90％ was 75.9％ and 5 year survival rate of the patients whose preoperative relative body weight was below 90％ was 64.7％(p=0.0118).
Conclusion : In gastric cancer patients who lose less weight preoperatively and maintain good relative body weight, the prognosis is good. Postoperative weight change has no influence on the prognosis.
