Liver is the most common site of metastatic disease in colorectal cancer. Superior response rate was demonstrated in trials comparing hepatic arterial administration of cytotoxic agents with systemic chemotherapy.
METHODOLOGY: Records of 109 consecutive patients with colorectal carcinoma metastatic to the liver treated by regional chemotherapy, who underwent implantation of a port system into hepatic artery or portal vein tributaries between 1991 and 1999, were reviewed and survival was evaluated. RESULTS: The median survival from diagnosis was 24 months.
Survival was significantly longer for patients treated by radical resection, and patients treated in 1997-1999. CONCLUSIONS: Patients treated by liver resection had the best outcome, while patients with extrahepatic diseases had poor prognosis.
The prognosis of patients treated by regional chemotherapy improved significantly with the advent of irinotecan and better selection.
