Radiotherapie Target Objectives for Tonsillar Cancer Treated With Unilateral Radiotherapie—a Replanning Studie From TROG 12.01

Unilateral radiation therapy (URT) is an effective treatment strategy in selected patients with lateralized tonsil cancer. However, there is a lack of established planning guidelines for URT treatment, leading to suboptimal optimization of contralateral and midline organs at risk (OARs). This study aimed to reoptimize URT plans to maximize sparing of midline and contralateral OAR’s while maintaining target coverage, providing dosimetric guidelines for URT planning.
