대장암 환자에서 선암의 십이지장과 빈창자로의 전이

Abstract

Colorectal cancer is one of the most commonly encountered gastrointestinal malignancies. For the care of patients with colon cancer, early detection of metastasis is very important since it offers a chance to cure this disease. Therefore, common metastatic sites for colon cancer are well-known. However, the small bowel is not a common metastatic site for the colon cancer. Here we report a patient who received resection and chemotherapy for his colon adenocarcinoma and developed cancer in the small bowels 3years later. Suspected lesions should be biopsied and examined for a primary neoplasm to differentiate from de novo carcinoma originated from small bowel. Histologic analysis revealed metastatic adenocarcinoma. Although there is a reported case of duodenal metastasis from a primary angiosarcoma of the colon, this is the first report on small bowel metastasis in a patient with colon cancer. Here, we report the case together with a review of literature. (Cancer Prev Res 16, 189-193, 2011)
