Viral Load Changes in Lymphoma Patients With HCV Infection After Chemotherapy
Viral Load Changes in Lymphoma Patients With HCV Infection After Chemotherapy
In last few years, most researches about hepatic complication after chemotherapy focused on
 hepatitis B virus (HBV). With adequate prophylaxis and monitor, HBV-related hepatitis flares
 can be prevented. In contrast, cancer patients with hepatitis C virus (HCV) infection are
 traditionally considered as relative safe to receive chemotherapy. However, two large
 retrospective studies recently showed that severe hepatitis could develop in 14-27% lymphoma
 patients with chronic HCV infection, including 3-4% hepatic failure. The risk factors to
 predict severe hepatitis are pre-treatment elevated ALT level and liver cirrhosis. Due to the
 lack of prospective studies, the dynamic changes of serum HCV RNA levels and the association
 of hepatitis are still unclear.

 Some epidemiologic studies demonstrated an association between HCV infection and B-cell
 lymphoma. Diffuse large B-cell lymphoma (DLBCL) is the most common lymphoma and several
 reports showed higher prevalence of HCV infection among DLBCL patients than the controls. HCV
 infected DLBCL patients are reported to have distinct clinical characteristics, such as
 older, more with elevated LDH levels, and more with extra-nodal involvement. Regarding the
 impact of HCV infection on prognosis, the results are conflicting. Taiwan is an endemic area
 of HCV but there are limited reports addressing the clinical characteristics and prognosis in
 this unique population.

 Therefore, the investigators initiate a prospective, multi-center observational study to
 clarify the dynamic association between serum HCV RNA levels and hepatitis in HCV-infected
 lymphoma patients treated with chemotherapy.
