An illuminating piece in the jigsaw of Hodgkin lymphoma risk stratification.

The management strategy of classical Hodgkin lymphoma in children is focussed on maximising therapeutic efficacy while minimising treatment-related toxicity via a risk-adapted and response-based approach. By using volumetric PET parameters, the report of Milgrom and her colleagues shows that combining pretreatment volumetric quantitative PET data with the early response assessment PET2 scan improved risk stratification in children with high-risk classical Hodgkin lymphoma treated on the COG AHOD0831 trial.
