[Adjuvant hepatic arterial infusion after resection of hepatic metastasis from colorectal cancer].

We examined retrospectively the efficacy of hepatic arterial infusion (HAI) chemotherapy comparing systemic treatment as adjuvant therapy after the curative resection of hepatic metastasis from colorectal cancer. Seventeen cases of HAI and 8 of the systemic treatment were enrolled in this study. We compared the pattern of recurrent sites and the overall survival rate between the two groups. There was no difference in a patients' background. Intrahepatic recurrence rate was lower and extrahepatic recurrence rate was higher in the HAI group, but not significant. The 1-, 3-, and 5-year overall survival rate was 94, 72, and 49% in the HAI group and 100, 100, and 50% in the systemic treatment group (p = 0.29), respectively. HAI chemotherapy did not contribute to the elongation of survival time in comparison with systemic treatment. This study indicates that there is no efficacy of HAI alone after the resection of hepatic metastasis from colorectal cancer and that there is need to use systemic chemotherapy together with HAI to prevent an extrahepatic recurrence.
