Repeated hepatic dearterialization for unresectable carcinomas of the liver: report of a 10-year experience.
The effectiveness of repeated hepatic dearterialization (RHD) therapy was evaluated in 26 patients with unresectable primary and secondary liver tumors. RHD was performed in 12 patients with hepatocellular carcinoma (HCC), 7 with hepatic metastases from colorectal carcinoma, and 7 with hepatic metastases from gastric carcinoma. It was repeatedly carried out by occluding the hepatic artery for 1 h twice daily. All patients concurrently received an intra-arterial infusion of anticancer drugs. More than 50% remission of the hepatic tumors, defined as a partial response (PR), was demonstrated in 8 patients (31%). A higher PR was seen in hepatic tumors from metastatic gastric cancer (5 out of 7 patients; 71%). Most patients who suffered severe complications had HCC with liver cirrhosis. These preliminary results suggest that RHD with intra-arterial chemotherapy is an acceptable palliative treatment for patients with unresectable liver metastasis from gastric cancer; however, the majority of patients with HCC are not responsive to such treatment, primarily because most have underlying cirrhosis predisposing to the development of postoperative complications at an unacceptably high rate.
