Classic Hodgkin lymphoma.

ABSTRACT

Classic Hodgkin lymphoma (HL) is rare disease, with an incidence of approximately 85,000 patients globally per year and a predilection for adolescents and young adults (ages 15-39). Since the introduction of combination chemotherapy in the 1960's and radiation dating back to the early 1900's, therapeutic options and by extension, clinical outcomes have improved dramatically with 5-year overall survival (OS) approaching 90% today. [1](#ref-0001) Advances in understanding HL biology have additionally facilitated development of targeted agents and immunotherapy which have further improved short and long-term outcomes. Despite continued improvements in up-front and salvage therapy, long-term survivors of HL experience several treatment-associated late toxicities, thus, along with efforts to improve therapeutic efficacy, efforts to reduce late effects remain a high-priority in the field.
