Despite advancements, locoregional control (LRC) remains a significant challenge, with 15%-50% of patients experiencing locoregional recurrence, negatively impacting OS and quality of life. Hypoxia within tumor cells is a critical factor contributing to treatment failure, necessitating higher radiation doses to achieve similar therapeutic effects as in normoxic cells. This study aims to investigate the role of dose escalation using [18F] fluoromisonidazole (FMISO) positron emission tomography/computed tomography (PET CT) to target hypoxic sub-volumes in head and neck cancer (HNC) to improve LRC.</p><p><strong>Methods: </strong>The dose-escalated hypoxia-adjusted radiotherapy trial is an open-label, parallel, randomised, single-centre, phase II study. Patients with HNC will undergo [18F]. FMISO PET CT to identify hypoxic regions. Normoxic patients will be labeled as Arm 1 and will not be part of the primary assessment. Patients with hypoxia will be stratified into two arms (2 and 3). Arm 2 will receive standard radiotherapy of 70 Gy in 2 Gy fractions, while Arm 3 will receive an additional boost to the hypoxic sub-volumes, delivering a total of 80 Gy (Phase 2).
