Infection with hepatitis B and C viruses, social class and cancer.

摘要: The hepatitis B and C viruses (HBV HCV) are major etiological factors in the occurrence of hepatocellular carcinoma (HCC) worldwide, but most especially developing countries where majority liver cancer cases can be found. In parallel with geographic distribution HCC, high levels HBV endemicity concentrated world. association between chronic infection low social class is quite strong; socioeconomic such as educational attainment, lower stratum, crowded urban residence have been reported to predict higher carrier prevalence both developed countries. More importantly, effect poverty on clearly evident among younger age groups, earlier seems increase risk development HCC. As assays for detecting HCV antibodies only recently become available, data relationship status much fewer. However, limited number studies that investigated seroepidemiology report an indicators class. It would appear striking correlation HCC largely related impact spread probably HCV.
