The score functions reflected the target and OAR goals routinely employed in our clinic and recorded on the formalized objective sheets. They were defined prior to commencement of the AP evaluation. The OAR score values are based on biological endpoints 20 , 21 , 22 , 23 and attempt to capture the physician's perception of the relative importance of different dose goals. Taking the parotid gland as an example, the maximum available score is 15, relative to the target coverage maximum score of 25. This reflects the facts that curing cancer is considered more important than preserving salivary function and that the parotids are not the only saliva‐producing glands. The parotid dose/score points are based on the simplified version of the normal tissue complicated probability (NTCP) curve from Dijkema et al. (23) who plotted the probability of saliva flow ratio at 1 year reduced to <25% against the mean parotid dose. As seen in Table 3, 15 points is awarded for the mean dose of 15 Gy (∼5% NTCP), 10 points for 26 Gy (∼25% NTCP), and 5 points for 39 Gy (≤50 NTCP). No points are awarded above 39 Gy. Thus the AP5 average mean parotid dose PQM score in Table 3 (74.8%) is equivalent to 0.748×15=11.2 points. From the plot in Fig. 3, it translates back into the absolute dose of 23.7 Gy. Similar calculations can be easily performed, if desired, for every objective in Table 3.
