Feasibility and safety of anti-PD1 first-line treatment of classic Hodgkin lymphoma: do we see the full picture?

Classic Hodgkin lymphoma (cHL) is highly curable with risk-adapted first-line treatment. Due to exceptional efficacy, antiprogrammed cell death protein 1 antibodies (aPD1) are increasingly incorporated into first-line treatment. However, the short- and long-term immune-related adverse event burden in this setting is insufficiently understood. Here, we review the currently available evidence on the feasibility and safety of aPD1 first-line cHL treatment. A more harmonized and complete reporting is critical to enable a detailed understanding and comprehensive assessment of aPD1-related morbidity.
