[Hepatic arterial infusion with irinotecan for the colorectal cancer patient with liver metastasis--a case report].

A 53-year-old woman who had been treated for rectal cancer was admitted to our hospital with edema, abdominal distension, and general fatigue. Abdominal CT showed multiple liver metastases and paraaortic lymph node metastases. After she was administered irinotecan by hepatic arterial infusion, the liver metastases decreased and paraaortic lymph node metastases were remarkably reduced in size.
