Human papillomavirus (HPV) infections with low-risk genotypes (6, 11) can cause benign hyperplasia such as condylomas and papillomas. Persistent infections with high-risk genotypes (16, 18, 31, 33, and 51) are associated with cervical, vaginal, vulvar, and head and neck malignancies. 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.
Detection of both low-risk (6, 11) and high-risk genotypes (16, 18, 31, 33, and 51) of human papillomavirus DNA in paraffin-embedded human tissue
This test, when not accompanied by a pathology consultation request, will be answered as either positive or negative. If additional interpretation/analysis is needed, please request test 70012 / Pathology Consultation along with this test.
The probe set used in this human papillomavirus (HPV) DNA in situ hybridization (ISH) test cannot detect all potential HPV serotypes that are associated with oropharyngeal squamous cell carcinoma. Following a negative DNA ISH result, a more sensitive in situ RNA test may be performed, if clinically indicated, at the discretion of the Mayo pathologist.
Results are reported as positive or negative for low-risk genotypes 6, 11, and/or high-risk genotypes 16, 18, 31, 33, and 51.
If additional interpretation/analysis is needed, request 70012 / Pathology Consultation along with this test.
