Approximately 10%–30% of patients with Hodgkin's lymphoma (HL) experience relapse or refractory (R/R) disease after first-line standard therapy. Brentuximab vedotin (BV) and immune checkpoint inhibitors (ICIs) have important roles in the salvage treatment R/R HL. However, subsequent for HL to BV and/or ICI is challenging. We retrospectively analyzed two institutions who had HL, experienced failure, received radiotherapy (RT) thereafter. The overall response rate (ORR), duration (DOR),...
