[A case of stage IV colon cancer effectively treated with tegafur uracil/calcium folinate in a patient on hemodialysis].

A 61-year-old man on hemodialysis due to chronic renal failure caused by diabetes mellitus was diagnosed as having ascending colon cancer with multiple liver metastases. Colonoscopy revealed a Type 2 tumor located in the ascending colon. Abdominal CT showed hepatic tumors in S8 measuring 8×7 cm and in S6 measuring 5×4 cm, with a number of small tumors in the other sites. In order to prevent a hemorrhage from the colonic tumor, laparoscope-assisted right colectomy was performed. Seventeen days after the operation, oral administration of tegafur uracil(300mg/body/day)and calcium folinate(75mg/body/day)was initiated for the treatment of hepatic metastases. After three courses of treatment, size reduction of the hepatic metastases(the S8 4×3. 5 cm and the S6 2. 5×2. 5 cm)was obtained. Although nine months with seven courses of chemotherapy had passed without significant side effects, the size of hepatic metastases increased. Currently, therefore, CPT-11 and cetuximab are being administered as second-line treatment.
