Abstract
Cancer arisen in an ileostomy is rare and no previous reports on chemotherapy for liver and lung metastases of the ileostomy cancer have been seen. We have resected cancer arisen in an ileostomy after excision of total colon and rectum and performed chemotherapy for postoperatively appeared liver and lung metastases. The case involved a man in his fifties who underwent total colectomy with a diagnosis of adenomatous coli and colorectal cancer at the age of 27 ; followed by rectal amputation and ileostomy for cancer of the rectal remnant at the age of 35. In 2009, he was diagnosed as having cancer of the ileostomy and underwent removal of the ileostomy and re-creation of an ileostomy. Metastases to the liver and lung were confirmed 2 months after the operation. Because an immunohistochemistry of the primary tumor revealed intestine-type adenocarcinoma, we employed chemotherapy in accordance with colorectal cancer that resulted in disappearance of the lesions. The chemotherapeutic effect was once rated as CR. No consensus of chemotherapy for small bowel carcinoma has been established as yet. Here we present an employment of chemotherapy for ileostomy cancer in accordance with colorectal cancer considering its mucin producing pattern, with which we could have a certain effect.
