PRECIS: Intraarterial delivery of 50 mg/m2 cisplatinum on a monthly basis is a well-tolerated regimen for patients with nonresectable hepatoma. The selective uptake of cisplatinum delivered intraarterially suggests other selective intraarterial protocols would be of use in regional cancers treated with cisplatinum. BACKGROUND: Sixty-seven patients with nonresectable hepatoma were treated with hepatic artery infusions (HAI) of 50 mg/m2 cisplatinum on a monthly basis. METHODS: Forty-eight patients received an initial course of whole liver external radiation with intravenous (i.v.) cisplatinum 50 mg/m2. Nineteen patients did not receive radiation and received HAI cisplatinum only. All patients then received HAI cisplatinum at 50 mg/m2 on a monthly basis. Six patients were given a tracer dose of radioactive 195m cisplatinum for quantitation by the HAI and i.v. routes. RESULTS: Monthly HAI cisplatinum was well tolerated and could be repeated indefinitely. Median survival for primarily treated nonresectable hepatomas was 12 months [alpha fetoprotein (AFP) elevated] and 17.5 months (AFP negative). Radioactive cisplatinum given by HAI yielded 34-55% tumor uptake of cisplatinum vs. < 5% by i.v. delivery. CONCLUSIONS: Hepatic intraarterial cisplatinum at 50 mg/m2 is a well-tolerated monthly regimen for patients with nonresectable hepatoma.
