This prospective interventional study evaluates the predictive value of tumor mutational burden, liquid biopsy biomarkers (including circulating tumor DNA), angiogenic factors, and dynamic contrast-enhanced magnetic resonance (MR) perfusion imaging in patients with HPV-negative oropharyngeal squamous cell carcinoma treated with concurrent chemoradiotherapy. The aim is to improve prediction of treatment response and disease course after treatment, support decision-making regarding optimal therapy, and potentially reduce the number of imaging examinations required during follow-up.
