Abstract

Alpha-fetoprotein (AFP) messenger RNA (mRNA) may be a potential marker of the dissemination of hepatocellular carcinoma (HCC) cells into the circulation. The aim of this prospective pilot study was to assess the prognostic value of quantitative levels of AFP mRNA in patients undergoing ablative treatment for HCC. Peripheral blood samples were taken from seven patients before and after treatment for measurement of AFP mRNA levels by reverse-transcriptase polymerase chain reaction (RT-PCR). Patients were treated with percutaneous radiofrequency thermal ablation (n=3) or transarterial chemoembolization (n=4). The level of AFP mRNA in blood was serially determined, and the time course was related to the clinical course and disease outcome. The median duration of follow-up was 14 months (range, 9-16 months). HCC recurred locally in four patients, and lung metastases developed in two of them. Patients were divided into three groups on the basis of the pre- and post-treatment AFP mRNA status. Group 1 included four patients with consistently high serum AFP and AFP mRNA levels (pre- and post-treatment). These patients developed distant and local recurrence. Group 2 included a patient with serum-negative AFP mRNA and normal AFP levels at...Continue Reading
