Objective Although the majority of human papillomavirus (HPV)-positive oropharyngeal squamous cell carcinomas have a favorable prognosis, we search for markers of poor prognosis by carefully examining a subset of highly aggressive cases. Study design Seven patients with HPV-positive oropharyngeal cancer who presented with non-pulmonary distant metastasis or developed distant metastasis posttreatment were identified. Eight control cases were chosen which responded well to treatment. Pathologic and radiologic studies were reviewed and compared. Results Two cases displayed a small cell carcinoma (SmCC) component upon pathologic review. Biomarker analysis revealed lower expression of NOTCH1 in the aggressive cohort in comparison to controls (P = .04). Cases showed a predominance of clustering of lymph nodes, extracapsular spread, and central tumor necrosis. Conclusion Although most HPV-related oropharyngeal cancers display a positive prognosis, it is evident that there is a subset, which behaves more aggressively. This early investigation identifies pathologic and radiologic features that may help to predict this behavior.
