[Intraarterial and intraportal chemotherapy combined with decollateralization for cholangiocellular carcinoma and metastatic liver cancer].

Two patients with cholangiocarcinoma and one patient with liver metastasis from inflammatory breast cancer underwent catheterization into both hepatic artery and portal vein following decollateralization using silicone rubber sheeting. They received arterial chemoembolization and chemotherapy and portal chemotherapy through the catheters repeatedly. Two patients with cholangiocarcinoma are still alive more than one year after the beginning of the treatments without regrowth of the tumors. The patient with metastatic liver cancer died of lung metastasis, although the liver foci were controlled by procedure. Thus, both intraarterial and intraportal chemotherapy combined with decollateralization by silicone rubber sheeting seems to be effective for advanced cholangiocarcinoma and metastatic carcinoma.
