Head and neck radiotherapy quality assurance conference for dedicated review of delineated targets and organs at risk: results of a prospective study

Abstract Purpose: Head and neck (HN) radiotherapy (RT) is complex, involving multiple target organ at risk (OAR) structures delineated by the radiation oncologist. Site-agnostic peer review after RT plan completion often inadequate for thorough of these structures. In-depth contours critical to maintain high-quality optimal patient outcomes. Materials Methods: In August 2020, HN Quality Assurance Conference, a weekly teleconference that included least one oncology specialist, was activated our institution. Targets OARs were reviewed in detail prior creation. A parallel implementation study recorded factors outcomes reviews. major change any modification high-dose planning volume (PTV) or prescription dose/fractionation; minor intermediate-dose PTV, low-dose OAR. We analysed results consecutive contour first 20 months since its initiation. Results: total 208 patients treated 8 providers reviewed: 86·5% from primary tertiary care hospital 13·5% regional practices. recommended 14·4% implemented 25 30 cases (83·3%). 17·3% 32 36 (88·9%). survey participants found all ( n = 11) strongly agreed conference useful. Conclusion: Dedicated targets/OARs with subspecialist associated substantial rates suggested modifications contours.
