PO-0723 POSSIBLE ADVANTAGES OF PROBABILISTIC PLANNING FOR HEAD AND NECK CANCER

To investigate possible advantages of uncertainty based probabilistic planning (PP) compared to conventional margin- based planning applied to five head and neck (HN instead, both systematic and random errors are explicitly handled during optimization and evaluation. We hypothesized that thanks to a PP approach we would be able to maintain the dose to the tumour target while decreasing the dose to the Organs at Risks (OAR)
