In this paper, the P＋＋ optimization strategy has been verified by evaluating （intensity-modulated radiation therapy, IMRT） plans for a T4 stage NPC patient in the situation where diffieuh compromise has to be made between probabilities for tumor control and normal tissue injuh＇y. The results showed that including the biological objective gEUD into the plan optimization couht decrease the mean dose of OAR. Theoretically, P＋＋ optimization strategy could be helpfnl to find the refined optimization solution for radiation therapy planning. However, in clinical radiotherapy practice, disease situations will form restrictions to use the biological evaluation only. More factors including both physical and biological models should be considered in a planning evaluation process to aehieve a best clinical solution.展开更多
