Simple Summary Autologous stem cell transplantation (ASCT) represents a standard strategy for patients with relapsed and refractory (RR) Hodgkin Lymphoma (HL). Unfortunately, patients displaying some pre-transplant adverse predictors eventually progress, requiring further treatments and several succumb to their lymphoma. This retrospective multicenter study aimed to evaluate the effectiveness of programmed death receptor-1 (PD-1)-blockade as a consolidation treatment for patients with RR-HL at high risk of ASCT failure. We collected data from 26 patients with >= 2 risk factors for recurrence who had received anti-PD1 consolidation after ASCT. Patients received a median of 13 consolidation courses (range 6-30), without toxicity-related discontinuations. At a median follow-up of 25.8 months post-ASCT, the median progression-free (PFS) was 42.6 months, with a 2-year PFS and overall survival rates of 79% and 87%, respectively. Post-ASCT consolidation with anti-PD1 is feasible and effective and may represent a valuable management option for patients at high risk of recurrence. (1) Background: Consolidation therapy is an emerging strategy for patients with relapsed/refractory (RR) Hodgkin Lymphoma (HL) at high risk of failing salvage autologous stem cell transplantation (ASCT).

Abstract
Simple Summary Autologous stem cell transplantation (ASCT) represents a standard strategy for patients with relapsed and refractory (RR) Hodgkin Lymphoma (HL). Unfortunately, patients displaying some pre-transplant adverse predictors eventually progress, requiring further treatments and several succumb to their lymphoma. This retrospective multicenter study aimed to evaluate the effectiveness of programmed death receptor-1 (PD-1)-blockade as a consolidation treatment for patients with RR-HL at high risk of ASCT failure. We collected data from 26 patients with >= 2 risk factors for recurrence who had received anti-PD1 consolidation after ASCT. Patients received a median of 13 consolidation courses (range 6-30), without toxicity-related discontinuations. At a median follow-up of 25.8 months post-ASCT, the median progression-free (PFS) was 42.6 months, with a 2-year PFS and overall survival rates of 79% and 87%, respectively. Post-ASCT consolidation with anti-PD1 is feasible and effective and may represent a valuable management option for patients at high risk of recurrence.
