Run by Copenhagen University Hospital, Rigshospitalet · NCT07817641 · Data updated 2026-11-12
This study tests whether using proton therapy for mediastinal lymphoma can lower late-toxicity risk compared with photon therapy in adults.

Is this trial a fit for you?
✓Likely a good fit
Adults (18+) with Hodgkin or non-Hodgkin lymphoma confined to the mediastinum (± neck/axilla) who are candidates for curative radiotherapy and can attend full treatment and follow-up.
✕Probably not a fit
Patients whose disease extends beyond the mediastinum or who cannot complete radiotherapy may not benefit.

What this trial studies
This national trial examines the feasibility of delivering proton therapy for mediastinal lymphoma across Danish centers and compares the calculated toxicity risk reduction from proton plans to the actually delivered plans. It prospectively collects acute and late side effects and explores a model-based approach to selecting patients for proton therapy. Eligible patients are adults with Hodgkin or non-Hodgkin lymphoma whose disease is confined to the mediastinum ± neck/axilla and who are planned for curative treatment. The study documents treatment plans, delivery, and toxicity outcomes to understand real-world differences between predicted and delivered toxicity risks. Participation requires informed consent and adherence to follow-up visits.
Why it matters
Potential benefit: If successful, proton therapy could reduce late toxicity from mediastinal lymphoma, potentially lowering the risk of secondary cancers and heart-related side effects.
How similar studies have gone: Previous studies have explored proton therapy for mediastinal cancers, but this national model-based selection and delivered-plan comparison provides new, more comprehensive evidence.
