Assessment of alpha-fetoprotein in chronic HBsAg carriers and in HBsAg negative cirrhosis of the liver.

Alpha-fetoprotein (AFP) was assessed in 159 subjects with chronic liver disease, incl. 125 chronic HBsAg carriers (42 suffered from cirrhosis of the liver) and in 34 HbsAg negative cirrhotic patients. In the group of 83 patients with chronic hepatitis B a slightly elevated AFP value was recorded in 7.2%, however, during the check-up examination it was already normal. During a one-year follow up hepatocellular carcinoma (HCC) was revealed in 4 of 42 HBsAg positive cirrhoses (9.5%) and in 2 of 34 (5.9%) HBsAg negative cirrhoses, the difference was not, however, significant. Five patients with HCC had markedly elevated or rising AFP value, one patient had abnormal AFP level despite advanced HCC. All cases of HCC were diagnosed late, in one patient radical treatment was not successful. We conclude that to improve the adverse prognosis of patients with HCC it is necessary to follow-up prospectively all patients with cirrhosis of the liver by sonography twice a year and examine after the same time intervals serum AFP to detect early stages HCC where there is still some chance of successful treatment.
