The incidence of human papillomavirus (HPV) DNA in archival formalin-fixed, paraffin-embedded tissue sections from verrucous carcinoma of the larynx was determined using polymerase chain reaction (PCR) with consensus primers and by in situ hybridization designed to detect HPV types 6/11, 16/18, 31/33/35. HPV DNA was detected in 17 (85%) of 20 tissue samples by PCR; none of the 20 samples were positive for the seven genotype types tested by in situ hybridization. PCR is a valuable tool to detect HPV and therefore will significantly clarify the importance of HPV in squamous mucosal disorders.

Purpose: Blood-borne, cell-free DNA has been proposed as a means of individualizing the management of human papillomavirus (HPV)-positive oropharyngeal carcinoma.
Methods And Materials: This study was designed based on the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P) statement. A comprehensive literature search of peer-reviewed publications from January 2013 to January 2024 was undertaken to identify prospective studies pertaining to the use of circulating HPV-DNA for oropharyngeal carcinoma.
To assess the diagnostic accuracy of self-collected urine and vaginal samples for the identification of precancerous cervical lesions in the referral population using high-risk human papillomavirus (hrHPV) assays based on polymerase chain reaction (PCR). It was a prospective study carried out in China from June 2021 to March 2022. The vaginal and urine samples were collected and analyzed by using a newly developed specific hrHPV PCR test, and matched cervical samples were analyzed by using an approved hrHPV DNA test.

We found that tumor-specific, HPV-human DNA junctions are detectable in serum cell-free DNA of a fraction of cervical cancer patients at the time of initial treatment and/or at six months following treatment.

Background: Induction chemotherapy (IC) followed by chemoradiation (CRT) is one treatment approach for patients with locoregionally advanced oropharyngeal squamous cell carcinoma (OPSCC) associated with human papillomavirus (HPV). This pilot study aimed to assess whether a circulating tumor (ct) DNA assay outperforms PET-CT in assessing treatment response in patients with HPV + OPSCC treated with induction chemotherapy (IC) followed by chemoradiation (CRT).
Materials And Methods: Patients treated with IC and definitive CRT for HPV + OPSCC were included.

All papillomaviruses encode an E2 protein and it is essential for the viral life cycle. E2 has three domains; a carboxyl-terminal DNA binding and dimerization domain, an amino-terminal protein interaction domain and a hinge region linking these two. Following homo-dimerization human papillomavirus E2 binds to four 12bp palindromic DNA sequences located in the non-coding long control region (LCR) of the viral genome.
