A Study of Adaptive Radiotherapy of Head-neck Cancer Using Daily Replanning and Optimization of the Treatment Plan. (DART-HN)

March 26, 2026 updated by: Jeppe Friborg, Rigshospitalet, Denmark

DART-HN - Daily Adaptive Radiotherapy of Head-neck Cancer.

Radiotherapy of head-neck cancer is associated with significant side effects. Using daily online adaptive radiotherapy to account for the changing anatomy, radiation to organs at risk can be lowered. We will investigate whether this is feasible and associated with a reduction in the risk of toxicity.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Daily online adaptive radiotherapy for head and neck cancer
Patients will undergo daily online adaptive radiotherapy for all fractions in the treatment course. The treatment plan will be re-optimised following recontouring on a daily basis using the Siemens-Varian Ethos Platform.
Radiation: Daily online adaptive radiotherapy
The patients will undergo daily online adaptive re-optimisation of the radiotherapy treatment plan following daily recontouring.
