77.8 percent (35/45) of liver function tests and 60.8 percent (31/51) of hepatitis investigations were normal and the negative percentage of serum alpha-fetoprotein(AFP), carcinoembryonic antigen (CEA), CA19-9 and CA125 were all rather high, suggesting these tumor markers were not suitable predictors for this malignant hepatic tumor either. This evidence concerns the gene CEACAM5 and hepatitis A virus infection.
