[Local transcatheter arterial chemoembolization in the palliative treatment of inoperable hepatocellular carcinoma]

Abstract

Hepatocellular carcinoma is a tumor with high mortality. Adequate oncological therapy is essential to modify the poor prognosis. Transcatheter arterial chemoembolisation has been proposed as a useful and well-tolerated treatment for unresectable carcinoma. In the study 51 patients with unresectable carcinoma (mean age 61.6, range 45-81, Child-Pugh A = 34 patients, Child-B = 13, Child-C = 4; Okuda I = 33 patients, Okuda II = 18) underwent chemoembolisation. A total of 122 procedure were performed, with a median number of 2.4 (range 1-6) per patient. One and two year survivals are 91% and 74% respectively (Child-A: 100% and 82%; Child-B: 100% and 63%; Child-C 0% at 1 year). The difference among the 3 groups is statistically significant (p = 0.001). Median overall survival is 20 months, with 22, 20 and 6 month in Child-A, B and C patients respectively (p = 0.006). Commonly reported side effects and biochemical changes included: fever, pain and increased serum amylase, transaminase levels. One patient developed a liver abscess and died of liver failure. In addition, in 18 patients (35%) mild to severe changes in glucose metabolism were also observed. Mild hyperglycemia was observed in 14 patients, with severe derangement in 4 patients (8%). It is suggested that careful evaluation of glucose metabolism is advisable in patients being considered for chemoembolisation. Their results confirm the usefulness of chemoembolisation in Child-A and B patients with unresectable hepatocellular carcinoma.
