Cancer | 1995

Detection of hepatitis C virus RNA in hepatocellular carcinoma by in situ hybridization.

Background. Hepatocellular carcinoma frequently is associated with chronic hepatitis C virus (HCV) infection. The presence of HCV in hepatocellular carcinoma has been detected by reverse‐transcription polymerase chain reaction of antigenomic HCV RNA, a tissue‐specific replicative form of the virus. Now, however, this method of detecting the presence of HCV has been invalidated by reports of antigenomic RNA in the blood or in peripheral blood mononuclear cells.
