Of the 100 types of human papillomaviruses (HPV), approximately 35 infect the genital tract. The viruses are categorized as "high risk" and "low risk" depending on whether they are known to cause cancer or not. Cervical cancer is an important cause of cancer mortality in Georgia, and worldwide. Only limited and incomplete data are available about the epidemiology of HPV infection and related molecular and cellular changes in Georgia. Objectives of our study included the estimation of the prevalence and the distribution of HPV genotypes among women in Georgia...

In the 21st century, an array of microbiological and molecular allow antigens for new vaccines to be specifically identified, designed, produced and delivered with the aim of optimising the induction of a protective immune response against a well-defined immunogen. New knowledge about the functioning of the immune system and host pathogen interactions has stimulated the rational design of vaccines. The design toolbox includes vaccines made from whole pathogens, protein subunits, polysaccharides, pathogen-like particles, use of viral/bacterial vectors, plus adjuvants and conjugation technology to increase and broaden the immune response...

Cervical cancer (CC) is one of the most common cancers among women worldwide. The relation of the human papillomavirus (HPV) with CC and its precursor lesions was first suspected for over 40 years. The indoleamine 2,3 dioxygenase (IDO) is an immune modulator enzyme responsible for the immune system tissue protection mechanism, which may be the key to the tumoural persistence. HPV oncoprotein E7 promotes the increase in cyclin-dependent kinase inhibitor p16 (CDKN2A/p16). The isolated and combined analysis of CDKN2A/p16 mRNA to CC diagnosis was done with promising results...

Introduction: Cervical cancer screening programs all over the world are being radically revised; preventive screening is increasingly based on detecting infection with human papillomavirus (HPV). This change was driven by large international studies (comparing cytological and HPV-based screening), which were then summarized in systematic reviews or HTA reports. We carried out a systematic comparison of these meta-analyses, comparing their contents, quality, results and recommendations. Material and Methods: A systematic search in MEDLINE identified eight meta-analyses...

BACKGROUND: Women positive to human papillomavirus (HPV+) testing at cervical screening need triage, typically cytology and immediate colposcopy in case of atypical squamous cells of undetermined significance (ASCUS) or worse (ASCUS+) or, in cytology-normal HPV+ women, HPV test repeat after 1 year and colposcopy referral if still HPV+. Our hypothesis was that substantial variations in triage positivity and sensitivity may produce little variation in overall referral to colposcopy and on sensitivity of the entire screening process...

BACKGROUND: Current US cervical cancer screening guidelines do not differentiate recommendations based on a woman's human papillomavirus (HPV) vaccination status. Changes to cervical cancer screening policies in HPV-vaccinated women should be evaluated. METHODS: We utilized an individual-based mathematical model of HPV and cervical cancer in US women to project the health benefits, costs, and harms associated with screening strategies in women vaccinated with the bivalent, quadrivalent, or nonavalent vaccine...

Prevention of cervical cancer has been unsuccessful in Japan because of low rates of cancer screening and vaccination. The Vaccine Adverse Review Committee of the Japanese Government investigated 2,475 adverse events and reported 617 (6.9/100,000) severe cases and 176 (2.0/100,000) cases with chronic pain. The proactive recommendation for human papillomavirus (HPV) vaccination has been suspended since June 2013. In this study, we examined vaccination rate and incidence of abnormal cervical cytology in women aged 20 to 24 years attending cancer screening in Miyagi...

BACKGROUND:  Uptake of the human papillomavirus (HPV) vaccine in the United States is slow, and the real-world effectiveness of the vaccine has not been assessed in high-risk adolescent populations. METHODS:  We conducted a longitudinal study of 1139 sexually-active, inner-city adolescent women receiving the 3-dose quadrivalent (4vHPV) vaccine. Cervical and anal specimens collected semi-annually were tested using a L1-PCR assay. Post-vaccination incidence of 4vHPV vaccine and non-vaccine HPV types, and risk of cervical cytological abnormalities, were assessed in relation to time-to-completion of all three vaccine doses...

Importance: The current American Joint Committee on Cancer/Union for International Cancer Control (AJCC/UICC) staging system, developed for human papillomavirus (HPV)-unrelated disease, discriminates poorly when applied to HPV-related oropharyngeal squamous cell cancer (OPSCC), leading to calls for a new staging system. Objective: To compare the prognostic ability of the AJCC/UICC seventh edition staging system; a recently proposed system, the International Collaboration on Oropharyngeal Cancer Network for Staging (ICON-S); and a novel objectively derived system for HPV-related OPSCC using a national database of patients primarily treated with either radiation or surgery...

Current sources of publicly available human papillomavirus (HPV) information may not adequately meet the needs of diverse families. This study sought to describe associations between sociodemographic and acculturation factors, and sources of HPV information among diverse parents and caregivers. Community organizations purposively recruited participants from African American, African refugee, Hispanic/Latino, American Indian, and Native Hawaiian and Pacific Islander communities for a 21-item survey (N = 228)...
