title: Alpha-fetoprotein, tissue polypeptide antigen and ferritin in diagnosing primary hepatocellular carcinoma in patients with liver cirrhosis.
abstract: This study was undertaken in order to compare the usefulness of three indices of tumour proliferation in detecting primary hepatocellular carcinoma (HCC) and in differentiating this neoplasm from liver cirrhosis. In 10 patients with HCC and in 63 with liver cirrhosis serum alpha-fetoprotein (AFP), tissue polypeptide antigen (TPA) and ferritin were assayed. Increased levels of AFP but not of TPA and ferritin were observed in HCC as compared to liver/cirrhosis. The receiver-operating characteristic curves demonstrated that AFP is more discriminating between HCC and liver cirrhosis than the other two markers. Correlations between liver function tests and serum markers were observed in liver cirrhosis but no in HCC. We can conclude that AFP is more useful than TPA and ferritin in detecting HCC in patients with liver cirrhosis, owing to the high frequency of false positive results of the latter two indices in liver cirrhosis. Liver dysfunction is probably involved in increasing all these markers of malignancy, thus reducing the specificity of these tests.
