A 45-year-old man was admitted to the hospital because of pelvic metastasis of colonic cancer in January, 1996. There were previous histories of undergoing a resectin of the transverse colon for an advanced colonic cancer in May 1994 and a low anterior resection with removal of paraaortic lymph nodes for recurrence to the mesosigmoideum in January 1995. In his family history, there were 7 patients with cancer in his relatives in the seventh degree. On February 7 1996, we inserted catheters from the bilateral superficial femoral arteries to the opposite internal iliac arteries and embolized bilateral upper, lower gluteal arteries with use of metallic coil. We indwelt a the port under the skin of his lower abdominal wall. Then intra arterial injection of CDDP, 5FU and leucovorin was started on February 19 and irradiation at a dose of 50Gy/25 fr was conducted for 6 weeks from April 1. The tumor was softened early in May. We confirmed the ulcer scar at the same portion with the colon endoscopy on May 2. He was discharged from the hospital without prominent side effects. Thereafter the intraarterial infusion chemotherapy was continued once a week on an ambulant basis. As of 1997, the tumor is slightly growing up, but we evaluate that this methods is valuable because symptomatic remission and a shrinkage of the tumor were obtained for a while.
