Elevation of serum MAGE-4 protein levels and prediction of hepatocellular carcinogenesis in patients with liver cirrhosis.

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.[1]
