Image-Guided Radiotherapy: Positioning Errors Affect Overall Survival
BARCELONA—The accuracy of radiation targeting using image-guided radiotherapy (IGRT) was significantly associated with overall survival in a study of a large cohort of patients treated with IGRT for their lung and esophageal cancers. reported at the 2018 European Society For Radiotherapy and Oncology (ESTRO 37) annual conference (ABSTRACT OC-0322, “Residual setup errors after IGRT are linked to overall survival in lung and oesophageal cancers”)
Cardiotoxicity
The key hazard was found to be unintended irradiation of the heart. Patients who had residual set-up errors which moved their hearts closer to the high-dose region had significantly worse overall survival compared to those who had a residual shifts away from the heart said first author Corinne Johnson MSc, a physics PhD student at Christie NHS Foundation Trust, University of Manchester and Manchester Cancer Research Centre in the UK in conversation with the Audio Journal of Oncology.
