摘要 Abstract Objective To detect hepatitis C virus (HCV) RNA sequences in the hepatic portal cholangiocarcinoma tissues and their relationship. Methods RNA was extracted from paraffin embedded cholangiocarcinoma tissues of 6 patients by guanidinium method, subjected to reverse transcription and then amplified by double PCR technique using nested primers from the highly conserved 5' noncoding region of HCV genome. Results HCV RNA of 5'NT sequences was found in the hepatic portal cholangiocarcinoma tissues of 5 out of 6 (83%) patients. Conclusions HCV RNA sequences present with high infectious rate in cholangiocarcinoma, and reverse transcription polymerase chain reaction (RT PCR) assay using primers derived from 5'NT region of HCV sequence is most useful in detecting HCV infection. The development of cholangiocarcinoma awaits further studies.
