Hepatitis C virus (HCV) is a significant healthcare problem affecting ~1% of the United States population. Meta-analyses of epidemiological studies reported a strong association between non-Hodgkin's lymphoma (NHL) and HCV. Direct oncogenic properties of HCV proteins and chronic antigenic stimulation are possible etiologies. We explored if NHL's prevalence has changed since older HCV therapy based on interferon that shared antiviral and anti-lymphoma properties was replaced with interferon-free direct-acting antivirals (DAA). We reviewed data from a nationwide database (Explorys, IBM) that aggregates records from 26 health-care-systems. We identified patients with chronic hepatitis C infection between June 2013 and June 2020. The control group was gender, race, and age-matched HCV-negative population. Statistical analysis used the odds ratio (OR) with P value <.001 for significance. There were 940 cases of NHL of 129,970 patients in the HCV group versus 107,480 cases of NHL of 37,961,970 in the control cohort [OR 2.6, 95% confidence interval (CI) 2.4-2.7]. A positive association was present for chronic lymphocytic leukemia, follicular lymphoma, marginal zone lymphoma, lymphoplasmacytic lymphoma, diffuse large B-cell lymphoma, Burkitt's lymphoma, non-Hodgkin T-cell lymphoma, and primary cutaneous T-cell lymphoma. There were no differences in Mantle cell lymphoma. The increased risk of HCV-associated lymphoma was persistent across genders, Caucasians and African-Americans, and age groups. While the risk of NHL in the HCV-negative population was higher in Caucasians than African-Americans (OR 1.8, 95% CI 1.7-1.8), the risk of HCV-associated NHL was not different. Further prospective studies examining the risk of HCV-associated lymphoma following DAA are warranted.
