Human papillomaviruses (HPV) may cause sexually transmitted disease. High-risk types of HPV are involved in the development of cervical cell dysplasia, whereas low-risk types may cause genital condyloma. Despite the association between HPV and cancer, donor sperm need not be tested for HPV according to European regulations. Consequently, the potential health risk of HPV transmission by donor bank sperm has not been elucidated, nor is it known how HPV is associated with sperm. The presence of 35 types of HPV was examined on DNA from semen samples of 188 Danish sperm donors using a sensitive HPV array. To examine whether HPV was associated with the sperm, in situ hybridization were performed with HPV-6, HPV-16 and -18, and HPV-31-specific probes. The prevalence of HPV-positive sperm donors was 16.0% and in 66.7% of these individuals high-risk types of HPV were detected. In 5.3% of sperm donors, two or more HPV types were detected. Among all identified HPV types, 61.9% were high-risk types. In situ hybridization experiments identified HPV genomes particularly protruding from the equatorial segment and the tail of the sperm. Semen samples from more than one in seven healthy Danish donors contain HPV, most of them of high-risk types binding to the equatorial segment of the sperm cell. Most HPV-positive sperm showed decreased staining with DAPI, indicative of reduced content of DNA. Our data demonstrate that oncogenic HPV types are frequent in men.

Objectives: we evaluated the hypothesis that level of ctHPVDNA on the first postoperative day (POD-1); and at 15 days (POD-15) could be associated with the need for adjuvant therapy and the presence of recurrence.
Materials And Methods: this is a prospective observational study on biomarkers, focusing on the longitudinal monitoring of ctHPVDNA in a cohort of HPV-OPSCC patients undergoing TORS. Blood samples were collected according to the following schema: (1) pretreatment; (2) on first postoperative day (POD 1); and (3) at 15 days (POD 15).

Human papillomavirus (HPV) underpins approximately 90% of squamous cell carcinomas (SCC) of the anus and perianal region. These tumors usually arise in association with precursor lesions such anal intraepithelial neoplasia/ high-grade squamous intraepithelial lesion (AIN 3/ HSIL), whereas a small subset of HPV-negative cancers may harbor mutations in TP53. Recently, vulvar lesions termed differentiated exophytic vulvar intraepithelial lesion/vulvar acanthosis with altered differentiated (DEVIL/VAAD) have been recognized as HPV-independent, TP53 wild-type precursors for vulvar carcinoma; however, analogous anal lesions have not been described.

Background: Oral cancer is a common head and neck cancer malignancy that seriously affects patients' quality of life and increases the health care burden. Moreover, there is a lack of comprehensive reviews of previous research on factors associated with oral cancer. The aim of the current umbrella review was to provide a comprehensive and systematic summary of relevant studies, to grade the quality of evidence of relevant studies, and to provide guidance for the prevention of oral cancer.

Background: This review aimed to emphasize the implications of DNA content in head and neck squamous cell carcinoma (HNSCC), focusing on its predictive value, role in patient stratification, and potential as a therapeutic target for this malignancy.
Methods: A narrative review of the literature was conducted through electronic database searches.
Results: In conventional HNSCC, aneuploid tumors are associated with increased lymph node metastasis, locoregional recurrences, poor response to radiotherapy and chemotherapy, and worse prognosis.

Objective: The objective of this paper is to study the association between obesity and tumor recurrence in patients with vulvar cancer.
Methods: This is a retrospective study including vulvar cancer patients from 2003 to 2022. Our primary outcome was progression-free survival (PFS) stratified by status of obesity, defined as body mass index (BMI) >30.
