title: Frequent microsatellite instability in post hepatitis B viral cirrhosis.
abstract: The molecular basis of cirrhosis, the most frequent underlying liver disease in hepatocellular carcinoma, remains unclear. We investigated microsatellite instability at six different loci on chromosomes 2p, 3p, 5q, 9p, 13q and 17p, in DNA from 38 cirrhotic livers of viral (n=28) and nonviral (n=10) origin. Sixty percent of the patients exhibited microsatellite alterations in at least one chromosome locus. A striking feature was the close association between genomic instability and cirrhosis linked to hepatitis B viral infection (P<0.01). This high instability may be a clue to the etiology of cancer induced by the hepatitis B virus.
