Staging HPV-related oropharyngeal cancer: Validation of AJCC-8 in a surgical cohort

The new AJCC-8 staging system represents a significant improvement over AJCC-7 for risk stratification into groups that predict overall survival and disease-specific survival of surgically treated HPV+ OPSCC patients. The AJCC- 8 pathologic staging system was not significantly better than the AJCC-8 clinical staging system for overall survival, however, the pathologic staging system was better than the clinical for disease free survival.
