Dose Painting of Head and Neck Cancer (RADPAINT)

February 19, 2025 updated by: Einar Dale, Oslo University Hospital

Dose Painting of Head and Neck Cancer - The RADPAINT Pilot Study

Dose-painting may increase the chance of cure at minimised radiation-induced toxicity in volumetric-arc radiotherapy (VMAT) for head and neck cancer. This trial (RADPAINT) investigates the safety of FDG-PET guided radiotherapy using VMAT dose-painting by contours for patients with head and neck cancer of poor prognosis.

Detailed Description

In this study, radiotherapy is planned using 18F-FDG PET/CT (18F-2-fluoro-2-deoxy-D-glucose fluorodeoxyglucose positron emission tomography) making one experimental "dose-painting by contours" SIB (simultaneous integrated boost) plan with a maximum point dose of 83 Gy. The participants will be given 73 Gy and 78 Gy minimum doses to two GTVs (gross tumor volumes inside the conventional GTV (68 Gy). GTV_73Gy and GTV_78Gy are determined from the SUV (standardized uptake values) from the 18F-FDG PET/CT according to the formula proposed by the Ghent group (Van der Straeten et al, R&O -06). It is expected to keep the level of normal tissue side-effects within or slightly above the level of conventional radiotherapy (i.e. maximum dose of 68 Gy).

In addition to the routine follow-up, the participants will be examined with 18F-FDG PET/CT (3 months after treatment and toxicity scoring at 6 weeks, 6 months, 1 year, 1.5 years and 3 years after radiotherapy (in addition to the routine follow-up).

Participant Group / Arm
Intervention / Treatment
Experimental: Dose painting
Radiation: FDG-PET guided dose painting
The radiation dose inside the gross tumor volume is increased according to the voxel intensity (SUV - standardized uptake value) of pre-treatment FDG PET.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Late toxicity - mucosal ulcer
Time Frame: 1 year
The study will be stopped if ≥ 2 patients experience mucosal ulcers grade ≥ 3 (CTCAE v 3.0/v4.0) without healing within the first year after radiotherapy. This endpoint will be assessed by clinical examination.
1 year
Acute or late toxicity
Time Frame: 1 year
Any life-threatening toxicity (CTCAE v4.0) related to radiotherapy. This endpoint will be assessed by clinical examination.
1 year

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Loco-regional control
Time Frame: 3 years
FDG PET/CT at 3 months. Imaging thereafter if clinical progression.
3 years
Disease free survival
Time Frame: 3 years
FDG PET/CT at 3 months. Imaging thereafter if clinical progression.
3 years
