New radiation approach aims to cut painful side effects in head and neck cancer
NCT ID NCT07580300
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests if proton radiation causes fewer side effects than standard photon radiation in people with head and neck cancer. About 400 adults aged 40 and older will receive either proton or photon therapy, plus possible chemotherapy. The main goal is to see if protons reduce problems like dry mouth, trouble swallowing, pain, and speech issues during the year after treatment.

Ability to fill in patient questionnaires and comply with study procedures. 7. Able to answer questionnaires in Norwegian or English. 8. Willing to travel to Oslo or Bergen for proton therapy if randomised to experimental arm. Exclusion Criteria: 1. Glottic cancers, cT1-T2 cN0 cM0. 2. Nasopharyngeal carcinomas, sino-nasal cancers, and head and neck salivary gland carcinomas. 3. Distant metastasis. 4. Previous radiotherapy to the head and neck. 5. Patients with pacemakers and/or implanted defibrillators. 6. Prior malignancy within the last 5 years. Not including radically resected non-melanoma skin cancer or low-risk early-stage prostate cancer. 7. Not able to participate due to equipment restrictions (weight limit treatment board 150 kg). 8.
