Detaljeret beskrivelse
In preparation for a randomised study in Denmark (DAHANCA 35) the feasibility of selecting newly diagnosed patients with squamous cell carcinoma of the pharynx or larynx for proton therapy at the local treatment centers is investigated. A proton and a photon doseplan is prepared for patients planned for primary radiotherapy . If proton radiotherapy reduces the anticipated absolute risk of dysphagia >= grade 2 (DAHANCA scale and/or xerostomia >= grade 2 (EORTC Head-Neck 35) with a clinical relevant value the patient is offered proton therapy at the Danish Center for Particle Therapy. The anticipated risk of xerostomia and dysphagia is estimated using Normal-Tissue Complication Models (NTCP).
At least five patients from each of the six Danish centers are required in this feasibility study.

Beskrivelse
Inclusion Criteria:
Patients with histologically proven squamous cell carcinoma of the pharynx or larynx planned for primary radiotherapy with curative intent
A predicted clinical significant reduction in the risk of any of the two primary endpoints (>= grade 2 observer-rated dysphagia or grade 2 patient-reported xerostomia) after proton therapy compared to photon therapy based on comparison of the individual patient dose plans
No current or earlier malignancies, which may influence treatment, evaluation or outcome of the head-neck cancer
Informed consent as required by law
Above 18 years of age
Exclusion Criteria:
Patient with cancers of the glottic larynx (stage I/II), skull base, sino-nasal area, nasopharynx, unknown primary tumor and prior malignancies.
Patients with contraindications for proton therapy (as per 2019 pacemakers, implanted defibrillators and tracheostomy)
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
