[GB virus-C infection in Chinese patients with hepatocellular carcinoma]
1Department of Infectious Diseases, First Affiliated Hospital, WCUMS, Chengdu 610041.
Insights
GB virus C (GBV-C) RNA was found in 26.6% of Chinese hepatocellular carcinoma (HCC) patients. Further research is needed to determine if GBV-C infection contributes to liver cancer development.
Area of Science:
- Hepatology
- Virology
- Oncology
Context:
- Hepatitis B and C viruses (HBV, HCV) are established risk factors for hepatocellular carcinoma (HCC).
- The role of GB virus C (GBV-C) in HCC pathogenesis remains largely unknown.
- Understanding viral associations with liver cancer is crucial for public health.
Purpose:
- To investigate the prevalence of GB virus C (GBV-C) RNA in Chinese patients with hepatocellular carcinoma (HCC).
- To explore potential correlations between GBV-C infection and clinical characteristics of HCC patients, including co-infection with HBV and HCV.
Summary:
- This study detected GBV-C RNA in 33 out of 124 (26.6%) HCC patients using nested RT-PCR and hybridization.
- GBV-C RNA positivity was observed in patients with and without HBV/HCV co-infection.
- No significant differences in clinical background were noted between GBV-C positive and negative HCC patients, except for a history of blood transfusion.
Impact:
- The findings indicate a high prevalence of GBV-C in Chinese HCC patients.
- Further research is warranted to elucidate the potential role of GBV-C in hepatocarcinogenesis.
- This study highlights the need for continued investigation into emerging viral threats associated with liver cancer.
Abstract:
Hepatitis B and C viruses (HBV, HCV) are closely related with hepatocellular carcinoma(HCC). The association between the new discovered GB-virus C (GBV-C) and HCC has not yet been known. In this study, 124 HCC patients were detected for the prevalence of GBV-C RNA by the one-step nested reverse transcription polymerase chain reaction (RT-PCR) and followed by hybridization using GBV-C probes located at 3'-untranslated region (3'-UTR) from its reported genomes. The results showed that 33 of 124 (26.6%) HCC cases were GBV-C RNA positive, including 12 cases positive HBsAg and anti-HCV, and 3 for cases negative HBsAg and anti-HCV. The clinical background of the patients with HBsAg and/or anti-HCV who were also positive for GBV-C RNA did not differ from the background of those who were negative for GBV-C RNA except the ratio of blood transfusion history. In conclusion, GBV-C has a high prevalence in Chinese HCC patients. Even though no sufficient data supports the causality of GBV-C on hepatocarcinogenesis, further researches aimed at whether GBV-C infection aggravates the incidence of HCC are warranted.
