Treatment of colorectal cancer hepatic metastases by hepatic artery chemotherapy.

Our clinical experience with 69 patients with metastatic colorectal cancer to the liver treated with hepatic artery chemotherapy is reviewed. All patients have had a minimum of six months follow-up. The Infusaid implantable drug delivery system was used by direct laparotomy in one third, and via the transaxillary approach in the remaining two thirds. Two thirds of the patients had at least 25 percent of the liver replaced with tumor. Chemotherapeutic agents included FUdR, mitomycin C, and BCNU. The overall response rate was 51 percent and 69 percent for the three-drug combination. Efficacy was not different in patients who had received prior systemic fluorouracil. Median survival from start of hepatic artery chemotherapy was one year.
