title: [Study of hepatocellular carcinoma type C by quantitation of serum HCV-RNA using branched DNA probe assay].
abstract: Serum HCV-RNA levels were determined by newly developed branched DNA probe (bDNA) assay in 87 patients with hepatocellular carcinoma (HCC), compared with 73 patients with chronic hepatitis active and 30 patients with liver cirrhosis. Patients with decompensated liver cirrhosis (LC-d) had a significant lower viremia (mean 3.2Meg.eq./ml, bDNA positive rate; 40%) than chronic hepatitis active (18.0; 64%) and compensated LC (LC-c, 17.9; 80%) (p < 0.05). Those data indicates that HCV replication may decrease as progression of LC. In contrast, there was no difference between the levels of HCC with LC-c (8.2; 85%) and LC-d (6.1; 89%), and their positive rate of bDNA assay were significantly higher than LC-d without HCC (p < 0.01). Therefore, patients undergoing LC in whom serum HCV-RNA sustained high level may correspond to the high risk group of HCC. In HCC of heavy drinker, serum HCV-RNA levels (11.3; 91%) were significantly higher than the levels (4.6; 79%) of HCC without heavy drink (p < 0.05). The result indicates that heavy drink may induced an increase in HCV replication.
