Post-treatment persistence of oral HPV in HNSCC predicts recurrence, death

Key clinical point: Persistence of detectable tumor-type HPV DNA in oral rinses after primary treatment of HPV-positive HNSCC identifies patients at high risk for poor outcomes.

Major finding: HPV-positive patients with persistent oral tumor-type HPV DNA had sharply higher risks of 2-year recurrence-free survival events (hazard ratio, 3.72; P less than .001) and death (hazard ratio, 6.61; P = .003).

Study details: Prospective cohort study of 396 patients with newly diagnosed oral cavity or oropharyngeal HNSCC.
