Background/Aims: The aim of this study was to determine the pharmacodynamics of cisplatin following three different treatment procedures for intrahepatic arterial infusion therapy for hepatocellular carcinoma (HCC). Methods: We divided 13 HCC patients into the following three groups: group A, lone injection of cisplatin (n=3); group B, combined injection of cisplatin and lipiodol, with embolization using small gelatin cubes (GCs) (n=5); and group C, injection of suspended lipiodol with cisplatin powder, with embolization using small GCs (n=5). In each group, the free cisplatin concentration in the hepatic vein was measured at 0, 5, 10, and 30 minutes. Results: The mean free cisplatin concentrations were as follows. For group A, the mean was 48.58 Ռg/mL at 0 minute, 7.31 mL at 5 minutes, 5.70 mL at 10 minutes, and 7.15 mL at 30 minutes. For the same time points, for group B, the concentrations were 8.66, 4.23, 3.22, and 1.65 Ռg/mL, respectively, and for group C, the concentrations were 4.81, 2.61, 2.52, and 1.75 mL, respectively. The mean area under the curve (AUC)0-infinity for the free cisplatin concentration was 7.80 in group A, 2.48 in group B, and 2.27 in group C. The AUC0-infinity for the free cisplatin concentration gradually decreased, from group A to group C. Conclusions: These results indicate that the combination of lipiodol and small GCs may be useful for delaying cisplatin drainage from the liver. (Gut Liver 2013;7:576-584)
