Objective
To review recent literature on human papillomavirus‐related (HPV‐positive) oropharyngeal squamous cell carcinoma (OPC) and focus on implications of recurrent and metastatic disease.
Methods
Primary articles from 1990 to 2016 indexed in MEDLINE (1) pertaining to the epidemiology of HPV‐positive OPC and (2) providing clinical insight into recurrent and metastatic OPC.
Results
The incidence of HPV‐positive OPC is increasing globally. HPV‐positive OPC is a subtype with distinct molecular and clinical features including enhanced treatment response and improved overall survival. While disease recurrence is less common in patients with HPV‐positive OPC, up to 36% of patients experience treatment failure within eight years. Recurrent and metastatic OPC has historically signified poor prognosis, however recent data are challenging this dogma. Here, we discuss recurrent and metastatic OPC in the context of HPV tumor status.
Conclusion
HPV‐positive OPC exhibits distinct genetic, cellular, epidemiological, and clinical features from HPV‐negative OPC. HPV tumor status is emerging as a marker indicative of improved prognosis after disease progression in both locoregionally recurrent and distant metastatic OPC.
