Adaptive daily replanning of radiotherapy for head and neck cancer.

Official title: DART-HN - Daily Adaptive Radiotherapy of Head-neck Cancer.

Run by Copenhagen University Hospital, Rigshospitalet · NCT07506902 · Data updated 2026-11-12

This tests whether doing same-day replanning of radiotherapy each treatment can reduce side effects for people receiving curative radiotherapy for head and neck squamous cell carcinoma.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults with histologically proven squamous cell carcinoma of the pharynx or larynx planned for primary curative radiotherapy, stage I–IV (excluding early glottic T1–T2N0), ECOG 0–2, able to attend daily treatments and follow-up at the study center.

Probably not a fit

Patients unlikely to benefit include those with prior head and neck radiotherapy, distant metastases, non-squamous histology, cancers of the skull base/sinonasal area or early glottic tumors, or those unable to attend daily treatment sessions.

What this trial studies

The intervention uses daily online adaptive radiotherapy with same-day replanning and optimization to account for anatomical changes during a curative course of radiotherapy for pharyngeal or laryngeal squamous cell carcinoma. Imaging is acquired before each fraction and the treatment plan is modified to spare nearby organs at risk when anatomy has shifted. The main goals are to test feasibility of the workflow and to see if daily adaptation lowers radiation dose to healthy tissues and reduces acute and late toxicity. Eligible patients are treated at Rigshospitalet in Copenhagen and include adults with histologically proven pharynx or larynx SCC (stage I–IV excluding T1–T2N0 glottic), ECOG 0–2, without prior head and neck radiotherapy or distant metastases.

Why it matters

Potential benefit: If successful, this approach could lower radiation exposure to healthy tissues and reduce both short- and long-term treatment-related toxicities such as swallowing dysfunction and dry mouth.

How similar studies have gone: Prior dosimetric and small feasibility studies have shown that online adaptive radiotherapy can spare organs at risk, but large randomized evidence demonstrating reduced clinical toxicity remains limited.
