The clinicopathological features and operative results in a cancer of the remnant stomach--risk and prevention of cancer after partial gastrectomy

Abstract

The clinicopathological features and operative results were analyzed in 21 patients undergoing an operation for cancer of the remnant stomach between 1979 and 1997. The twenty-one patients were divided into two groups: Group A; n = 9: who had undergone a gastrectomy for benign gastric disease, Group B; n = 12: who had undergone the same operation for gastric cancer. In Group A, the interval between the first gastrectomy and the second was longer than in Group B. In both groups, a large number of advanced cancers (n = 16, 76.2%) and undifferentiated carcinomas (n = 15, 71.4%) were seen. Five-year-survival rates in Group A and Group B were 23.7%, 19.0%, respectively. The incidence of gastric stump cancer following partial gastrectomy was 80% in the patients on whom Billroth II reconstruction had been performed after gastrectomy. It is suggested that the residual stomach in the Billroth II reconstruction patients is susceptible to cancer development. Consideration of the reconstruction method and a systemic follow-up is needed to improve a prognosis.
