The Effects of Hepatic Artery Chemotherapy on Viral Hepatitis in Patients With Hepatocellular Carcinoma

Transcatheter arterial chemoembolization (TACE) or arterial Yttrium-90 (⁹⁰Y) microspheres are used to treat unresectable hepatocellular carcinoma (HCC), but little is known about their effects on viral hepatitis. The aim of this study was to determine their effect on viral hepatitis in patients with HCC. We carried out a retrospective review of patients treated for HCC. Worsening of viral hepatitis was determined by serum chemistry and viral loads where available. Fifty-two patients treated with TACE were followed for a mean of 22.0 months. Thirty-nine patients (75%) had decreased/stable tumor. Two of the 39 (5%) patients with decreased/stable tumor burden had a sustained increase in bilirubin. None had a sustained ALT elevation or significant increase in viral load after TACE. Twenty-four patients treated with ⁹⁰Y microspheres were followed for a mean of 12.0 months. Twenty-two of these had a decreased/stable tumor burden and no patient had a significant elevation of ALT. However, 7 of the 22 had a sustained bilirubin elevation. We conclude that neither TACE nor ⁹⁰Y treatment was associated with worsening viral hepatitis in this group of HCC patients. The presence of chronic viral hepatitis with normal bilirubin should not exclude the use of these therapies in patients with unresectable HCC.
