New in the RedJournal: replanned TROG 12.01 unilateral cases to define guidelines for unilateral RT planning with maximal midline and contralateral sparing. @TROGfightcancer RadOnc HNcsm.

Unilateral radiotherapy (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 re-optimize URT plans to maximize sparing of midline and contralateral OAR’s while maintaining target coverage, providing dosimetric guidelines for URT planning.
