    Abstract:
    Hepatitis B virus (HBV) DNA in the serum of 31 patients with histologically confirmed primary hepatocellular carcinoma (PHC) from Malaysia and Indonesia was quantitated by densitometric scanning of autoradiograms obtained by Southern blot DNA hybridization, after electrophoresis using a 32P DNA cloned into plasmid pBR325 as a probe. This quantitation after electrophoresis is more informative than the usual spot hybridization technique. Five of the 31 sera were positive for HBV DNA. Levels ranged between 1.36 pq and 143.18 pq per ml of serum, and the levels of HBsAg, anti-HBs, anti-HBc, HBeAg and anti-HBe in the serum were serologically determined. All five sera positive for HBV DNA were also positive for HBsAg. Three of the five positive for HBV DNA were positive for HBeAg and negative for anti-HBe. Two of the sera positive for HBV DNA were negative for HBeAg but positive for anti-HBe. All sera negative for HBV DNA were also negative for HBeAg. Many sera which were negative for HBV DNA and HBeAg were positive for HBsAg. Of the 31 sera from PHC patients, 23 had at least one HBV marker positive (74.2%).
