[Targeted chemotherapy of hepatocellular carcinoma with SMANCS/Lipiodol--how to use SMANCS/Lipiodol].
The first drug only for arterial injection, SMANCS/Lipiodol, which offers targeted chemotherapy for hepatocellular carcinoma (HCC), now commercially available. Based on our experience using SMANCS/Lipiodol for 424 patients with HCC, the golden standard of how to use SMANCS/Lipiodol for complete necrosis of tumor was described. The initial dose of SMANCS/Lipiodol was varied 2 to 6 mg per body, mainly depending on the size of the tumor. All feeding arteries of HCC have to be verified on angiogram, and the drug must be injected via an adequate artery. Sometimes, a tumor changes its feeding arteries. Additional administrations with an interval of one month were done till the entire tumor was filled with SMANCS/Lipiodol (grade 4). One or two months after achievement of grade 4, we must examine how much drug was removed from tumor on CT. If the entire tumor is not filled with the drug, further injections are recommended to maintain grade 4. Almost all tumors shrank in 3 to 4 months while maintaining grade 4. Frequent administration of low doses (1-3 mg per body) is recommended. Discontinvation of administration was done on the following findings; tumor size reduction of over 90% or complete disappearance of tumor stain. With arterial injection therapy of SMANCS/Lipiodol, survival of patients with unresectable HCC was prolonged, especially in 272 patients who were good candidates for therapy. (Those with Child C liver cirrhosis, with a tumor occupying all four segments of the liver, and/or with extrahepatic spread at initial arterial injection of the drug were excluded.) The 1, 2, 5, and 10 year survival rates were 83%, 58%, 34%, and 25%, respectively.
