Persistent Hepatitis C Viremia Following Sofosbuvir/Velpatasvir During Bendamustine-Rituximab Therapy for Follicular Lymphoma

This highlights the possibility that chemotherapy may have contributed to failure to achieve sustained virologic response despite otherwise appropriate direct-acting antiviral therapy.
