Mapping of sentinel lymph node drainage using SPECT/CT to tailor elective nodal irradiation in head and neck cancer patients (SUSPECT-2): a single-center prospective trial

摘要

Dose reduction to organs at risk. Boxplot of planned mean irradiation doses to organs at risk. For every patient treated within the SUSPECT-1 study, two plans were made: a unilateral plan based on the results of the SPECT/CT, that was used to treat the patient, and (for comparison purposes) a regular bilateral plan they would have been treated with outside the framework of the study. The mean doses to all these organs at risk were significantly lower in the unilateral plan, compared to the regular bilateral plan. Abbreviation: Gy: gray
