A clinicopathological study of 10 cases of primary small bowel adenocarcinoma

Abstract

Between 1989 and 2009, 10 patients with small bowel adenocarcinoma were treated in our hospital. These tumors appeared in the jejunum in 6 patients and in the ileum in the remaining 4 patients. All patients had some symptoms. The median size of the tumors was 50mm(30-110mm). All tumors were advanced type 2 lesion with severe stricture. Histologically there were 8 well, 1 moderately and 1 poorly differentiated adenocarcinomas. There were 8 tumors invading the serosa and 2 tumors invaded other organs. Positive lymph nodes were identified in 6 cases. Liver metastasis and peritoneal dissemination were identified in 3 and 4 cases, respectively. Eight cases were diagnosed as small bowel adenocarcinoma preoperatively by double balloon endoscopy. The 4 patients with stage II tumor and 2 patients with stage III tumor underwent curative-intent surgery. The 4 patients with stage II tumor are all surviving without evidence of disease now.
