HN-QUEST: A Study of Head and Neck Imaging Biomarkers

The purpose of this study is to develop and investigate novel and established MR (magnetic resonance) imaging sequences as predictive and prognostic radiotherapy biomarkers. Radiotherapy is a fundamental treatment modality for Head and Neck Squamous Cell Carcinoma (HNSCC) with a majority of patients receiving radiation as part of their care pathway. Although treatment is effective, there remains a risk of failure particularly in those presenting with locally advanced disease. In addition, significant proportion of patients receiving radiotherapy will suffer long-term side effects related to their treatment. The addition of concurrent chemotherapy improves the efficacy of radiotherapy, but at the cost of increased treatment related toxicity. The treatment related toxicity and risk of treatment failure means there is a compelling clinical need to personalize therapy based on a patient's early response to radiotherapy.
