Summary
Brief summary (as posted)
This study will investigate the possible relationship between infection with hepatitis C virus (HCV) and the development of certain hematologic cancers (Non-Hodgkin's lymphoma, Hodgkin's lymphoma, chronic lymphocytic leukemia, multiple myeloma) and thyroid cancer. HCV causes chronic hepatitis, cirrhosis, and liver cancer. It is transmitted primarily through injection drug use and transfusion of infected blood. Studies have shown that HCV may also be linked to hematologic cancers and thyroid cancer. This retrospective study will examine medical records from veterans with and without HCV infection who previously received treatment in the Veterans Administration medical system. Data collected on each subject will include the subject's race, sex, age and era of military service, presence of liver disease or thyroiditis at their baseline clinic visit, number of inpatient visits in the past 5 years and outpatient visits in the past year, and the presence of various specified cancers. The prevalence of cancer and other conditions among HCV-infected subjects and non-HCV infected subjects at baseline and the subsequent development of the cancers of interest in these two groups will be compared and analyzed for a possible causal relationship.
