Oropharyngeal cancer is a disease in which malignant (cancer) cells form in the tissues of the oropharynx. The gold standard to diagnose this disease is through RNA qPCR. In 2011, Schache et al. determined the accuracy of Human Papilloma Virus p16  immunohistochemistry (p16 IHC) in detection of oropharyngeal carcinoma. Results from 200 patients are shown in the table below: see photo Compute for the sensitivity of p16 IHC in diagnosis of oropharyngeal carcinoma.   Source: Schache, A. G., Liloglou, T., Risk, J.
