Novel imaging classification system of nodal disease in human papillomavirus‐mediated oropharyngeal squamous cell carcinoma prognostic of patient outcomes

Background Matted nodes in human papillomavirus (HPV)‐mediated oropharyngeal squamous cell carcinoma (OPC) is an independent predictor of distant metastases and decreased overall survival. We aimed to classify imaging patterns of metastatic lymphadenopathy, analyze our classification system for reproducibility, and assess its prognostic value. Methods The metastatic lymphadenopathy was classified based on radiological characteristics for 216...
