Random aneuploidy in chronic hepatitis C patients.
Hepatitis C virus (HCV) has been recently recognized as a potential cause of B-cell lymphoma. Both chronic hepatitis B and C with or without cirrhosis represent major preneoplastic conditions, and the majority of hepatocellular carcinomas arise in these pathological settings. According to the aneuploidy-cancer theory, carcinogenesis is initiated by random aneuploidy, which is either induced by carcinogens or arises spontaneously. The aim of this study was to evaluate random aneuploidy rate in HCV patients during chronic infection and remission (past infection eradicated), compared with non-Hodgkin lymphoma (NHL) patients and healthy controls. To determine random aneuploidy, we applied the FISH technique with probes for chromosomes 9 and 18. Significantly higher random aneuploidy rate was found in the HCV-infected and lymphoma patients than in the control group; the past HCV group in remission had intermediate rates, between those of the control group and the chronically infected patients. Patients who have eradicated HCV infection may nonetheless carry higher risk for future malignancy and therefore need long-term follow-up.
