The diagnostic value of plasma abnormal prothrombin (PIVKA-II) measurements in detecting relatively small hepatocellular carcinomas (HCC), less than 5 cm in diameter, was compared with that of serum alpha-fetoprotein (AFP) determinations. Among 18 patients with relatively small hepatocellular carcinoma (HCC), abnormal PIVKA-II values were found in only three (16.6%). Highly elevated serum AFP levels (greater than 200 ng/ml) relatively specific for HCC were seen also in three patients. However, nonspecific elevation of PIVKA-II in patients with liver cirrhosis not accompanied by HCC was much less than that of AFP. Although complementary, both tests appear to be of limited value in early detection of HCC, indicating that searches for other markers are necessary, to allow early detection of small HCC.
