Abstract
Lipiodolization—selective regional cancer chemotherapy using Lipiodol plus an anticancer drug (LPD)—can prolong survival time of patients with an unresectable hepatocellular carcinoma (HCC). To enhance understanding of LPD's influence on the cirrhotic liver, we carried out related studies. Forty‐three cirrhotic patients with HCC were treated with LPD (epirubicin in a dose of 15–40 mg/m2 and Lipiodol of 0.02–0.25 ml/kg). Seven cirrhotic patients with HCC were subjected to hepatic angiography alone, and these subjects selected randomly served as controls. Among the 43 treated with LPD, 23 belonged to Child's class A, 15 to class B, and 5 to class C. Blood samples were taken before angiography (pre) and at 24 hours after angiography (post) from each patient. Post/pre ratio of the following parameters were compared between patients of the two groups: sGOT, sGPT, and LDH as a marker for hepatocyte injury; t. bilirubin and hepaplastin test (HPT) as hepatocyte function; alkaline phosphatase and γ‐GTP to examine bile duct injury; and serum hyaluronic acid level to determine an endothelial cell functions. Post/pre ratio of serum GOT, GPT, LDH levels, and HPT in patients treated with vs. without LPD were 1.32 ± 0.59 vs. 0.92 ± 0.09 (P < 0.001), 1.18 ± 0.43 vs. 0.88 ± 0.09 (P < 0.001), 1.11 ± 0.20 vs. 1.00 ± 0.07 (P < 0.05), and 0.95 ± 0.10 vs. 1.09 ± 0.12 (P < 0.01), respectively. There were no significant differences in post/pre LPD ratio of other parameters, rates of complications, and hospital stay after LPD for patients with Child's class A, B, and C. Hepatocytes are apparently the primary site of injury in cases of LPD. LPDs, using epirubicin in a dose of 15–40 mg/m2 and Lipiodol in a dose of 0.02–0.25 ml/kg, proved to be safe for cirrhotic patients with HCC.
