Nine patients with metastatic carcinoma involving the liver were treated by hepatic arterial chemotherapy with Angiotensin II (AGT II) using a subcutaneous implanted pump. There were two primary lesions in the breast, one in the stomach, three in the colon and three in the rectum. Every patient received intra-arterial bolus injection of 5-FU and Adriamycin with 3 mcg of AGT II weekly at our outclinic. Of 7 evaluable patients, 6 responded clinically with PR (response rate, 85.7%). No adverse effects were noted in relation to AGT II. AGT II combined with chemotherapy is therefore a safe and effective method for even outpatients with liver metastases.
