Objectives:
To determine the prevalence of hepatitis C virus (HCV) infection in patients with B-cell non-Hodgkin's lymphoma (NHL) in British Columbia.
Design:
A cross-sectional analysis.
Setting:
The British Columbia Cancer Agency (BCCA), a Canadian provincial tertiary oncology referral center.
Subjects:
Consecutive patients with B-cell NHL registered onto the BCCA lymphoma database in 1996 and part of 1997 and a control group of patients with T-cell NHL registered on the database from 1995 through 1997. Patients with HIV infection were excluded from the analysis. A second control group (n = 1085) consisted of health-care workers tested for HCV infection following a needle-stick injury.
Interventions:
Stored sera from patients with B-cell NHL (n = 88) and T-cell NHL (n = 37), identified from the database, were tested for the presence of HCV infection with commercially available serologic tests.
Main Outcome Measures:
HCV seropositivity in the B-cell lymphoma group compared to the control groups (T-cell NHL and health-care workers).
Results:
2.3% of the B-cell NHL group, none of the T-cell NHL group and 1% of the health-care worker control group were positive for HCV infection. These results were not statistically significantly different.
Conclusion:
Patients in British Columbia with B-cell NHL do not have an increased prevalence of HCV infection. These data suggest that the lymphotrophism of HCV may differ by regional, racial and genotypic variations around the world.
