Locoregional and Distant Recurrence for HPV-Associated Oropharyngeal Cancer Using AJCC 8 Staging

2002-2018

The objective of this study is to evaluate locoregional and distant failure for human papillomavirus-associated (HPV+) oropharyngeal squamous cell carcinoma (OPSCC) using American Joint Committee on Cancer eighth edition (AJCC 8) staging.

In the largest evaluation of HPV+ OPSCC after platinum-based chemoradiation using AJCC 8, risk for locoregional recurrence was stratified by smoking, T category, N category, and overall stage. Risk of distant recurrence was only stratified by smoking status and not related to stage. This has implications for surveillance and clinical trial design.
