The aim of this study was to determine whether MAGE-4 protein is detectable in sera of patients with hepatocellular carcinoma and other liver diseases. An enzyme-linked immunosorbent assay was employed for detection of MAGE-4 protein in sera of liver disease patients, healthy men and women (control I) and those undergoing prostatic cancer screening (control II). MAGE-4 protein levels in sera of patients with hepatitis C virus-associated HCC (HCC-C) (n = 45, mean = 2.160 ng/ml) and HCV-associated cirrhosis (LC-C) (n = 55, 1.072 ng/ml) were significantly higher (P < 0.0001) than those of control I (0.327 ng/ml) or control II (0.394 ng/ml). MAGE-4 protein was positive in 21/45 (46.7%) HCC-C patients and 18/55 (32.7%) LC-C patients (cut-off, mean plus 2 SD in healthy controls) but in 0/12 (0%) hepatitis B virus-associated HCC (HCC-B) patients, 3/49 (6.1%) hepatitis B virus-associated LC (LC-B) patients, 4/47 (8.5%) alcoholic liver disease patients, and 1/49 (2.0%) controls. Serum MAGE-4 protein level may be useful as a marker for identification of LC-C patients suffering from HCC that is undetectable by presently available methods.

Early detection of hepatocellular carcinoma (HCC) is clinically important because advanced HCC limits treatment modalities for the cancer. We have previously reported that serum levels of MAGE-4 protein are strongly associated with the development of HCC. The present study was designed to determine whether elevated serum MAGE-4 protein levels can predict hepatocellular carcinogenesis in patients with liver cirrhosis before clinical diagnosis. Among 62 cirrhotic patients, 28 patients were diagnosed with HCC during the follow-up period. The levels of MAGE-4 protein and alpha-fetoprotein (AFP) were significantly elevated in cirrhotic patients with HCC. Univariate and multivariate analyses suggest that elevated serum MAGE-4 protein is more significant than AFP. Importantly, retrospective analysis of prefrozen sera of cirrhotic patients revealed a transient or continuous elevation of serum MAGE-4 protein levels in 14 of 28 cirrhotic patients with HCC (50%) before clinical diagnosis. In contrast, elevated serum MAGE-4 protein levels were observed in 3 of 33 cirrhotic patients without HCC (9%), and in 2 of 34 hepatitic patients (6%). These results indicate that elevated serum MAGE-4 protein levels can be a predictive marker of hepatocellular carcinogenesis in cirrhotic patients, thereby enabling us to treat patients at an earlier stage.
