[Clinical study of the effect of cisplatin therapy in unresectable hepatocellular carcinoma].

Twenty-one cases of unresectable hepatocellular carcinoma (HCC), including 15 cases receiving intravenous infusion of CDDP in addition to transcatheter arterial embolization (TAE), and 6 cases receiving intraarterial infusion of CDDP in combination with sodium thiosulfate rescue (STS rescue) were studied. In the 15 cases given intravenous infusion therapy with TAE, favorable effects were observed in 33.3% of patients, and the 50% survival period was 22.5 months. In the 6 cases given intraarterial infusion, favorable effects were obtained in 66.6% of patients, but the 50% survival period was 2 months. The side effects observed most frequently were nausea and vomiting. All the other side effects observed were not so severe. These results suggest that intravenous CDDP infusion in addition to TAE is favorable, producing a life-prolongation effect.
