Stereotactic radiotherapy for ultracentral lung tumours

Cancer Radiother. 2023 Jul 27:S1278-3218(23)00130-0. doi: 10.1016/j.canrad.2023.06.021. Online ahead of print.ABSTRACTUltracentral (UC) lung lesions are generally defined by the presence of the tumour or the Planning Target Volume (PTV) abutting proximal bronchial tree (PBT) or the esophagus. Initial reports rose awareness regarding the potential toxicity of stereotactic body radiotherapy (SBRT) when delivered to UC lesions. Major concerns include necrosis, stenosis, and bleeding of the PBT. Technological improvements now enable the delivery of more accurate treatments, possibly redefining the historical "no-fly zone". In this review, studies focusing on the treatment of UC lesions with SBRT are presented. The narrow therapeutic window requires a multidisciplinary approach.PMID:37516640 | DOI:10.1016/j.canrad.2023.06.021
