NCT07506902

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Risk of dysphagia and xerostomia six months post-treatment assesed by normal-tissue complication probability (NTCP) models

    6 months after treatment

Study Arms (1)

Daily online adaptive radiotherapy for head and neck cancer

EXPERIMENTAL

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

Interventions

The patients will undergo daily online adaptive re-optimisation of the radiotherapy treatment plan following daily recontouring.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients with histologically proven squamous cell carcinoma of the pharynx or larynx planned for primary radiotherapy with curative intent No current or earlier malignancies, which may influence treatment, evaluation or outcome of the head-neck cancer Informed consent as required by law The patient cannot participate in conflicting protocols Stage I-IV (excluding T1-T2N0 carcinoma of the glottic larynx) ECOG/WHO performance status 0-2

You may not qualify if:

  • Patient with cancers of the glottic larynx (stage I/II), skull base, sino-nasal area and unknown primary tumor.
  • Inability to attend full course of radiotherapy or follow-up visits in the outpatient clinic Distant metastasis Previous radiotherapy of the head and neck Previous surgery for the primary cancer with curative intent
