About this trial
Hypoxia occurs in about 80% of head and neck tumors. Based on experimental and clinical data, hypoxia is a useful parameter for pretherapeutic stratification. These radioresistant regions can be detected with FMISO PET/CT. Moreover, hypoxic subvolumes of tumors can be evolving as target volumes for radiotherapy ("dose painting") in hypoxia imaging-based dose escalation.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Pathologically proven new diagnosis of oropharyngeal p16 negative, or laryngeal, hypopharyngeal, oral cavity (independent of p16) squamous cell carcinoma of clinical stage III, IV confined to head and neck area
Evaluable tumor burden assessed by computed tomography scan or magnetic resonance imaging, based on RECIST (Response Evaluation Criteria in Solid Tumours) version 1.1
Eligibiity for definitive chemoradiation or hyperfractionated accelerated radiotherapy
Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
Disqualifiers
Prior surgical treatment - any surgery of primary tumor or involved nodes or prior surgical debulking apart from surgery with diagnostic intention (e.g. open biopsy if necessary)
Prior systemic therapy, targeted therapy, radiotherapy treatment for head and neck cancer
Cancer outside of the oropharynx, larynx, and hypopharynx or oral cavity, such as nasopharyngeal, sinus, other para-nasal, or unknown primary head and neck cancer
Known active central nervous system (CNS) metastases and/or carcinomatous meningitis or any distant metastasis
