Matted nodes: High distant‐metastasis risk and a potential indication for intensification of systemic therapy in human papillomavirus–related oropharyngeal cancer

The purpose of this study was to determine whether matted nodes uniquely identify patients with human papillomavirus (HPV)-positive oropharyngeal cancer at disproportionately high distant failure risk who may benefit from intensified systemic therapy.One hundred seventy-eight patients with stage III/IV HPV-positive oropharyngeal cancer who completed definitive chemoradiotherapy were stratified by risk group (low-risk = T1-3/N0-2c/<10 pack-years;...
