[Evaluation of prophylactic intra-hepatic-arterial infusion chemotherapy after resection of hepatic metastases from colorectal primaries].

To prevent recurrence in the residual liver after surgical treatment for colorectal metastases, the efficacy of intermittent or continuous intra-hepatic-arterial chemotherapy was analyzed. The three- and five-year survival rate of patients with intermittent infusion of ADM or MMC (n = 11) was 36.4% and 36.4%, respectively, while the survival rate of the patients without the regional chemotherapy (n = 32) was 41.9% and 23.3%, respectively, indicating no statistical significance. On the other hand, one patient out of 8 with continuous infusion of 5-FU and 2 patients out of 6 without local chemotherapy developed recurrent disease during the median follow-up time of 12 months. No serious complication such as sclerotic cholangitis or hepatic necrosis was observed. Although the follow-up was not long enough to accurately evaluate the efficacy, local chemotherapy with continuous infusion of 5-FU could be a promising method as an adjuvant chemotherapy after hepatic resection for colorectal metastases.
