Probability of response and dosimetric data for several organs at risk. Average values of the probability of complications in each organ at risk, PI, the mean dose, Dmean and the maximum significant dose, Dmax. The error bars indicate the standard deviation of all planned cases. The colour bars show the biologically converted dose to a fractionation schedule of 2 Gy per fraction. The grey bars show nominal or physical dose values obtained with the prescribed fractionation. The larynx was not used during treatment planning in the past and therefore it was not included in treatment planning optimization. However with the prescribed dose escalation and to maximize normal tissue sparing all organs located close to the PTV should be delineated and considered during optimization.
