Allogeneic hematopoietic stem cell transplantation in r/r Hodgkin lymphoma after treatment with checkpoint inhibitors: Feasibility and safety.

This is the largest pooled analysis of its kind published so far. Our results suggest that allogeneic HSCT after CPIs is feasible and not associated with higher mortality. However, careful consideration should be given for prevention, early detection, and effective treatment of GVHD in these cases. Additional prospective studies are needed for further clarification.
