Figure 1From: Adaptive and innovative Radiation Treatment FOR improving Cancer treatment outcomE (ARTFORCE); a randomized controlled phase II trial for individualized treatment of head and neck cancer Dose in the redistributed radiotherapy regimen. Transverse (left) and coronal (right) view with isodose lines. In the dose-painted redistriburtion radiotherapy regimen, the GTV-FDG-PET is defined by an automatic iso-contour at 50% of the maximum uptake in the primary tumour. This is expanded by 3mm to form the PTV-FDG-PET. The GTV-primary should at least encompass the GTV-FDG-PET and is expanded by 10mm to form the PTV-primary. The PTV-FDG-PET will receive 35 fractions to a maximum total dose of 84 Gy to 2% of the volume (PTV-FDG-PET), a minimum dose of 70 Gy and a mean dose of approximately 77 Gy. The PTV-primary outside the PTV-FDG-PET will receive 35 fractions to a total mean dose of 67 Gy (ranging from 64-70 Gy).Back to article page
