INTRODUCTION: Cervical cancer is a major public health issue in Uganda, with high incidence due to limited screening especially in rural areas. In 2019, HPV DNA testing using GeneXpert was rolled out to improve screening access. Assessing progress and challenges since its introduction is important. AIM: To determine genotype distribution and explore health worker experiences with HPV screening using GeneXpert in Uganda. METHODS: We conducted a retrospective cohort study where HPV screening data from 66 GeneXpert labs from March 2021-May 2023 country wide was analyzed...

BACKGROUND: Postoperative radiotherapy radiation therapy (PORT) for early-stage human papillomavirus (HPV)-positive oropharyngeal squamous cell carcinoma (OPSCC) with positive lymphovascular invasion (LVI) has an unclear association with overall survival (OS). METHODS: This retrospective cohort study queried the National Cancer Database for surgically treated, T1-2, N0-1 HPV+ OPSCC from 2010 to 2019. Primary exposures were LVI and PORT, and the main outcome was 5-year OS...

We describe a case of rapid progression of cervical dysplasia to stage IVB cervical cancer in a previously healthy transgender young adult man on testosterone therapy. The cancer diagnosis came 7 months after routine pap smear showed low-grade dysplasia with high-risk human papillomavirus in preparation for gender-affirming hysterectomy/bilateral-salpingo-oophorectomy. After diagnosis, our patient faced unique challenges as a transgender man receiving gynecologic oncology care. This case highlights the challenges of and barriers to cervical cancer screening and treatment that transgender men confront...

Cervical cancer is caused in the vast majority of cases by the human papilloma virus (HPV) through sexual contact and requires a specific molecular-based analysis to be detected. As an HPV vaccine is available, the incidence of cervical cancer is up to ten times higher in areas without adequate healthcare resources. In recent years, liquid cytology has been used to overcome these shortcomings and perform mass screening. In addition, classifiers based on convolutional neural networks can be developed to help pathologists diagnose the disease...

Despite the ongoing global vaccination campaign aimed at preventing human papillomavirus (HPV) related health issues, the uptake of the HPV vaccine remains unacceptably low in developing regions, particularly in sub-Saharan Africa (SSA). Therefore, this systematic review and meta-analysis aimed at determining the pooled prevalence and associated factors of HPV vaccine uptake among adolescent school girls in SSA. Electronic bio-medical databases were explored. Pooled prevalence, publication bias, meta-regression, sub-group, and sensitivity analysis were performed...

Objective: To investigate the performance of human papilloma virus (HPV) typing as a triage tool in the management of patients with postcoital bleeding (PCB). Methods: All patients referred for colposcopy at a cervical pathology clinic of a nationwide health insurance organization, due to PCB and had a preceding high-risk HPV (hrHPV) test between 2018 and 2020, were retrospectively located. Demographic and pathologic data were collected from electronic medical files. Sensitivity, specificity, and negative and positive predictive value of hrHPV test according to final pathology were calculated...

BACKGROUND: The association of Human Papilloma Virus (HPV) and Human Syncytial Virus (HSV) infection with inflammatory and potentially malignant disorders of the oral cavity (OPMD) is unknown. The aim of this cross-sectional study was to stablish the expression of the p16INK4A and HSV proteins, to test potential correlation between those parameters in biopsies from clinically diagnosed oral lesions. METHODS: Immunochemical analysis of 211 formalin-fixed, paraffin-embedded (FFPE) blocks from 211 individuals was provided...

INTRODUCTION: Cervical cancer is the most common malignant tumor among women. It is the main cause of death among women in sub-Saharan African countries. Particularly, the incidence and mortality rates are highest in East Africa. Even though the burden of human papilloma virus-related cervical cancer is high in East Africa, there is no conclusive evidence about the prevalence of human papilloma virus vaccine uptake and its predictors. OBJECTIVE: To assess the pooled prevalence of human papilloma virus vaccine uptake and its determinants in East Africa...

Up to 56 million young and adult women of African origin suffer from Female Genital Schistosomiasis (FGS). The transmission of schistosomiasis happens through contact with schistosomiasis infested fresh water in rivers and lakes. The transmission vector is the snail that releases immature worms capable of penetrating the human skin. The worm then matures and mates in the blood vessels and deposits its eggs in tissues, causing urogenital disease. There is currently no gold standard for FGS diagnosis. Reliable diagnostics are challenging due to the lack of appropriate instruments and clinical skills...

OBJECTIVES: The addition of p16/Ki-67 dual immunostaining to human papilloma virus (HPV) screening tests has been shown to increase the detection rate of high-grade cervical intraepithelial neoplasia. Thus, the aim of this study was to evaluate the accuracy of p16/Ki67 dual staining in the detection of cervical intraepithelial neoplasia 2 (CIN2+) in women with high-risk HPV infection. MATERIALS AND METHODS: A cross-sectional study was conducted between August 2017 and August 2019 at the Chulabhorn Hospital in Bangkok, Thailand...

BACKGROUND: Recurrent respiratory papillomatosis (RRP) is a wart-like lesion mainly affecting the larynx, caused by human papillomavirus (HPV) genotypes 6 and 11. The disease affects both children and adults, and there is no cure. Surgery is the current symptom-relieving treatment; however, HPV vaccination is used as an adjuvant treatment. AIMS AND OBJECTIVES: The aims were to study effects of HPV vaccination in RRP cases and to compare juvenile-onset to adult-onset disease and high treatment frequency (TF) to low TF cases...

Cervical cancer (CC) is the fourth most common cause of cancer-related deaths amongst women worldwide. CC represents a major global healthcare issue, and Romania ranks the worst in mortality rates amongst EU countries. However, the early detection of CC can be lifesaving. To understand the testing process undergone by women in Romania, we performed a retrospective study, and investigated a cohort of 83 785 cervical cases from Romanian women aged 15-70, obtained in private-based opportunistic screening...

Head and neck squamous cell carcinoma (HNSCC) exhibits significant genetic heterogeneity and primarily concerns the oral cavity and oropharynx. These cancers occur more frequently in men with a 5-year survival rate below 50%. Major risk factors include human papilloma virus (HPV) (notably type 16), Epstein-Barr virus, tobacco, alcohol, and poor oral hygiene with approximately 4.5% of global cancers linked to HPV. Notably, differences in the microbiome between healthy individuals and patients with head and neck cancers (HNCs) have been identified...

Head and neck cancer (HNC) is the 6th most common cancer across the world, with a particular increase in HNC associated with human papilloma virus (HPV) among younger populations. Historically, the standard treatment for this disease consisted of combined surgery and radiotherapy or curative platinum-based concurrent chemoradiotherapy, with associated long term and late toxicities. However, HPV-positive HNC is recognized as a unique cancer subtype, typically with improved clinical outcomes. As such, treatment de-escalation strategies have been widely researched to mitigate the adverse effects associated with the current standard of care without compromising efficacy...

Oropharyngeal squamous cell carcinoma (OPSCC), a subset of head and neck squamous cell carcinoma (HNSCC), involves the palatine tonsils, soft palate, base of tongue, and uvula, with the ability to spread to adjacent subsites. Personalized treatment strategies for Human Papillomavirus-associated squamous cell carcinoma of the oropharynx (HPV+ OPSCC) are yet to be established. In this article, we summarise our current understanding of the pathogenesis of HPV+ OPSCC, the intrinsic role of the immune system, current ICI clinical trials, and the potential role of small molecule immunotherapy in HPV+ OPSCC...

The role of molecular markers is increasingly being recognized for head and neck tumors ranging from benign lesions like paragangliomas to malignancies like squamous cell carcinomas (SCCa). Multiple studies have recently validated blood tests for circulating tumor tissue modified viral- human papillomavirus DNA (HPV ct-DNA) ( NavDx, Naveris Laboratories ) for posttreatment surveillance of HPV-driven oropharyngeal SCCa. This technology quantifies fragments of circulating DNA that are shed into the blood stream with very high (>95%) positive and negative predictive values and are also highly sensitive in distinguishing tumor HPV-DNA from a non-cancerous source...

BACKGROUND: Cervical cancer eradication is one of the main goals for 2030 by the World Health Organization, which can only be achieved with high vaccination rates against Human Papilloma Virus. In Colombia, more and better scientific evidence is required to increase confidence in vaccination. The objective of this study is to evaluate the safety profile of the quadrivalent vaccine against HPV in the risk of developing autoimmune, neurological, and hematological diseases in adolescent women in Colombia...

PURPOSE OF REVIEW: There is still a need of biomarkers in the induction and neoadjuvant settings for squamous cell carcinoma of the head and neck (SCCHN). The objective of this concise review article is to give an overview on both predictive and prognostic biomarkers potentially useful for the management of SCCHN. RECENT FINDINGS: Human papilloma virus (HPV) positivity translated by the presence of the protein indicator p16 is synonymous of favorable prognosis SCCHN...

Introduction: The transmembrane channel-like (TMC) protein family contains eight members, TMC1-TMC8. Among these members, only TMC1 and TMC2 have been intensively studied. They are expressed in cochlear hair cells and are crucial for auditory sensations. TMC6 and TMC8 contribute to epidermodysplasia verruciformis, and predispose individuals to human papilloma virus. However, the impact of TMC on peripheral sensation pain has not been previously investigated. Methods: RNAscope was employed to detect the distribution of TMC6 mRNA in DRG neurons...
