Official title
A Phase I Trial of MR-Guided Dose-Escalated Hypofractionated Adaptive Radiation Therapy and Immunotherapy in Primary Metastatic or Very Locally Advanced Patients With Head and Neck Cancer
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Locoregional failure remains the principal mode of mortality in head and neck squamous cell carcinoma (HNSCC) treated with conventional chemoradiation therapy. Magnetic resonance-guided radiation therapy (MRgRT) allows for adaptive radiation dose escalation based on tumor response and may improve therapeutic outcomes while limiting toxicities. This protocol evaluates a novel framework for radiation delivery with concurrent atezolizumab in patients with advanced HNSCC. Dose-Escalated Hypofractionated Adaptive Radiotherapy (DEHART) modifies radiation dose using MRgRT by escalating radiation dose to residual tumor while deescalating radiation dose to areas of tumor regression.
