[Hepatectomy and intraarterial infusion chemotherapy for liver metastasis from colorectal cancer].

Hepatectomy and intraarterial chemotherapy for liver metastasis from colorectal cancer have been performed in our department. Intraarterial infusion chemotherapy has also been performed for unresectable liver metastasis. One hundred twenty-seven cases of liver metastasis from colorectal cancer were studied. The cases were divided into groups according to radicability of the original colorectal cancer, whether or not hepatectomy was performed, and whether or not they received intraarterial chemotherapy. Group I is cur C of origin. Group II is cur A or B without hepatectomy. Group III is cur A or B with hepatectomy. Each group was divided into a group without intraarterial chemotherapy (A) and a group with it (B). IA 23 cases, IB 13 cases, IIA 14 cases, IIB 21 cases, IIIA 28 cases, and IIIB 28 cases. The survival rate of group III was better than that of group II. The survival rate of group II was better than that of group I. There was no significant difference in survival rates between IA and IB. The survival rate of group IIB was significantly better than that of group IIA. The survival rate of group IIIB was significantly better than that of group III A. Hepatectomy and intraarterial chemotherapy after hepatectomy for liver metastasis from colorectal cancer were effective.
