Phase II Study of Intensity Modulated Radiotherapy in Dose Painting for Sinus Carcinomas After Endoscopic Surgery

"The target volumes to be delineated are as follows:~* High-risk CTV (Clinical Target Volume), corresponding to all initially invaded areas, as identified by comparison between the operative report and the anatomo-pathological report (ideally with histo-surgical mapping).~* Low-risk CTV, corresponding to naso-sinusal structures not initially invaded but at risk of recurrence, and located close to the high-risk target volume, including at least 5 mm around the high-risk volume and excluding non-risk areas (muscle, bone)."

"The target volumes to be delineated are as follows:~* High-risk CTV, including the entire post-operative cavity,~* Low-risk CTV, adapted from the recommendations described by Lapeyre (Cancer/Radiotherapy 2005), and including at least 5 mm around the high-risk volume, excluding non-risk areas (muscle, bone)."
