Clinicopathological characteristics and surgical outcome of patients with the gastric stump cancer following distal gastrectomy

摘要

We retrospectively reviewed clinical reports of 34 patients with gastric stump cancer (GSC) to analyze the clinicopathological features and prognostic factors. Histologically, the incidence of diffuse type was significantly prominent in patients with previous gastric benign disease than in those with previous malignant gastric disease. The overall 5-year survival rate was 53.3%. The presence of lymph node metastasis and pathological serosal invasion of the tumor tended to be associated with poor survival. Anastomotic location, tumor size greater than 5 cm, serosal invasion, the presence of lymph node metastasis, and stage III or higher were associated with poor survival. Early detection, especially attentive observation of anastomotic site, and sufficient surgical resection were important to obtain better outcomes of GSC.
