Judicious reduction in elective nodal volumes for patients with oropharyngeal squamous cell carcinoma (OPSCC) has the potential to reduce acute and long term toxicity while maintaining high rates of regional control. We postulated that the contralateral N0 neck region at highest risk for containing occult microscopic lymph node (LN) metastases in patients with OPSCC could be best defined by the location of the initial positive ipsilateral LN. We sought to identify and target this N0 elective neck region and assess impact on dose to organs at risk compared to using a consensus-defined contralateral elective nodal volume.Rights/Terms
