Clinical Trial Summary

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.


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).

Outcome

Type Measure Description Time frame Safety issue
Primary Late toxicity - mucosal ulcer 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
Primary Acute or late toxicity Any life-threatening toxicity (CTCAE v4.0) related to radiotherapy. This endpoint will be assessed by clinical examination. 1 year
Secondary Acute toxicity CTCAE v4.0 < 3 months after radiotherapy
Secondary Late toxicity CTCAE v4.0 1 year
Secondary Loco-regional control FDG PET/CT at 3 months. Imaging thereafter if clinical progression. 3 years
Secondary Disease free survival FDG PET/CT at 3 months. Imaging thereafter if clinical progression. 3 years
Secondary Overall survival Date from central registry. 3 years
