Human Papillomavirus (HPV) High-Risk E6/E7, RNA In Situ Hybridization
Use
This assay is intended to identify the presence of human papillomavirus (HPV) E6/E7 transcripts from high-risk genotypes. It is useful for the stratification of oropharyngeal squamous cell carcinoma. Patients with HPV-related oropharyngeal squamous cell carcinoma (OPSCC) have shown better disease-specific survival and overall survival when compared to HPV-negative cases of OPSCC.
