[Results of a 4-year of alpha-fetoprotein in Vietnam (1969--1973)].

ALPHA-Fetoprotein (alpha-FP) was revealed by the method of double diffusion in gel in 66% of hepatocellular carcinoma cases, but the frequency of findings both in hepatoma and in other diseases increased when electroimmunodiffusion (a more sensitive method) was used. Results of quantitative determination of alpha-FP in the patients after ligation of the hepatic artery pointed to reduction of its content in the blood serum, this confirming the value of its determination for prognosis.
