Clinical Data Without Patient Consent From The Metro North Hospital And Health Service Human Research Ethics Committee
Participants were prospectively recruited from the cohort of consecutive patients referred to the Combined Head and Neck Clinic (CHNC) at a large tertiary hospital in Brisbane between September 2013 and November 2014. For inclusion, all patients had to have at least one parotid gland affected by either primary, metastatic or recurrent disease, and were planned to receive either definitive XRT or surgery with postoperative XRT to a prescription dose of 60Gy or greater. Patients were excluded from the study if they were managed by surgery only, or received a dose of less than 60Gy. The study was conducted with ethical clearance from the Metro North Hospital and Health Service Human Research Ethics Committee (approval number: HREC/13/QRBW/444), which included a waiver of consent from the successful Public Health Act application to allow for auditing of clinical data without patient consent.
All patients underwent either three-dimensional conformal radiation therapy (3DCRT) or helical intensity modulated radiation therapy (H-IMRT). Consensus decision regarding which patients undergo H-IMRT as opposed to 3DCRT was made at the institutional triage meeting. The 3DCRT treatments were planned in Oncentra Masterplan (Elekta, Stockholm, Sweden) and delivered using a Varian Clinac iX linear accelerator (Varian Medical Systems, Palo Alto, CA, USA). The H-IMRT treatments were planned using a simultaneous integrated boost technique in the Hi-Art Planning Station…
