Five days of radiation instead of weeks: a new test for head and neck cancer
NCT ID NCT05648461
First seen Sep 11, 2026 · Last updated Sep 11, 2026
Summary
Researchers are testing a shorter radiation schedule for people with head and neck cancer who have had surgery. Standard radiation after surgery often takes several weeks, but this trial gives five treatments over five days. The study enrolls 50 adults with high-risk features, such as close surgical margins or lymph node involvement. Doctors track whether the shorter course controls the cancer and whether it causes severe long-term side effects.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a shorter course of radiation therapy after surgery
- What this could lead to
- If it works, this could offer a faster, more convenient radiation schedule for people with head and neck cancer after surgery.
- What could go wrong
- The trial is small and early. The shorter schedule may not control cancer as well as standard treatment, or it may cause unexpected side effects.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Aged 18 or above and less than 80 years. 2. Patient with high risk features: close (≤ 5mm) margin, presence of LVI or PNI, pT3-4. 3. Stage pT1-4 histological confirmed carcinoma of oral cavity with intermediate high risk feature. 4. Pathological N0 neck requiring ipsilateral neck PORT. 5. Karnofsky performance score greater or equal 70. 6. Timely delivery of PORT preferable within 6-12 weeks of surgery (additional delay of 1-3 weeks of delay beyond 12 weeks is permissible to accommodate for delayed wound healing or other logistics). 7. Written informed consent for treatment. 8. Available to attend long term follow- up. Exclusion Criteria: 1. Pathologically positive neck disease. 2. Positive margin. 3. Patients requiring bilateral neck RT. 4. Patients that require re-irradiation for recurrent disease. 5. Previous radiotherapy to the head and neck region. 6. Any invasive malignancy within the previous 2 years (other than non melanomatous skin carcinoma or cervical carcinoma in situ). 7. Age \< 18 years or \> 80 years.
