Potential correlation of human papillomavirus (HPV) 16 E6 variants and human leukocyte antigen (HLA) class II polymorphisms has been suggested in patients with cervical cancer, so far little information is available about the possible interaction between E6 variants and HLA class II variability during the obviously accelerated progression to cervical cancer in young women. In this study, we aimed to explore the association between the HPV16 E6 variants and HLA-DRB1, DQB1 alleles in a Chinese young cervical cancer population...

INTRODUCTION: The main risk factors for head and neck squamous cell carcinoma (HNSCC) are tobacco and alcohol consumption and human papillomavirus (HPV) infection. However, in a subset of patients, no risk factors can be identified. Glutathione S-transferase π (GTSP1) is a carcinogen-detoxifying enzyme that is activated by exposure to carcinogens, and it is associated with a reduction in response to toxic therapies. We studied the expression of GTSP1 in tumor and non-tumor tissue samples from patients with and without these risks to identify whether GTSP1 expression differs according to exposure to carcinogens...

BACKGROUND: Global health partnerships have grown rapidly in number and scope, yet there has been less emphasis on their evaluation. Gavi, the Vaccine Alliance, is one such public-private partnership; in Gavi-eligible countries partnerships are dynamic networks of immunization actors who work together to support all stages and aspects of Gavi support. This paper describes a conceptual framework - the partnership framework - and analytic approach for evaluating the perceptions of partnerships' added value as well as the results from an application to one case in Uganda...

BACKGROUND: Human papillomavirus (HPV) vaccination is below national goals in the United States. Health care providers are at the forefront of improving vaccination in the United States, given their close interactions with patients and parents. OBJECTIVE: The objective of this study was to assess the associations between demographic and practice characteristics of the health care providers with the knowledge of HPV vaccination and HPV vaccine guidelines. Furthermore, our aim was to contextualize the providers' perceptions of barriers to HPV vaccination and strategies for improving vaccination in a state with low HPV vaccine receipt...

OBJECTIVES: The increasing incidence of HPV-related Oropharyngeal Squamous Cell Carcinoma (OPSCC) and the improved survival of HPV-positive OPSCC highlight the need for effective tools in evaluating HPV status on formalin-fixed paraffin-embedded (FFPE) cancers. To date, there is no agreement regarding the most appropriate method for HPV testing on FFPE materials. We aimed to investigate the performance of the Xpert® HPV assay (Cepheid) on crude lysates from OPSCC FFPE tissues. MATERIALS AND METHODS: Crude lysates were obtained by proteinase K digestion of FFPE tissues that had already been analyzed by the INNO-LiPA HPV assay and p16(ink4a) immunostaining...

BACKGROUND: Cervical cancer screening has traditionally been based on cervical cytology. Given the aetiological relationship between human papillomavirus (HPV) infection and cervical carcinogenesis, HPV testing has been proposed as an alternative screening test. OBJECTIVES: To determine the diagnostic accuracy of HPV testing for detecting histologically confirmed cervical intraepithelial neoplasias (CIN) of grade 2 or worse (CIN 2+), including adenocarcinoma in situ, in women participating in primary cervical cancer screening; and how it compares to the accuracy of cytological testing (liquid-based and conventional) at various thresholds...

Human papillomaviruses have been implicated in many cutaneous diseases. Practicing dermatopathologists often consider using immunohistochemistry and in situ hybridization to help clarify the histologic diagnosis, particularly in cases with borderline or non-diagnostic features. We reviewed the current evidence behind the use of these two techniques in dermatopathology. We identified only two studies utilizing the currently available immunohistochemical antibodies. We found more evidence regarding the use of in situ hybridization; however, the majority of this evidence focuses on diagnosing condylomas and other lesions of the genital skin...

It is now recognized that the immune system can be a key component of restraint and control during the neoplastic process. Human papillomavirus (HPV)-associated cancers of the anogenital tract and oropharynx represent a significant clinical problem but there is a clear opportunity for immune targeting of the viral oncogene expression that drives cancer development. However, high-risk HPV infection of the target epithelium and the expression of the E6/E7 oncogenes can lead to early compromise of the innate immune system (loss of antigen-presenting cells) facilitating viral persistence and increased risk of cancer...

BACKGROUND: Forthcoming cervical cancer screening strategies involving human papillomavirus (HPV) testing for women not vaccinated against HPV infections may increase colposcopy referral rates. We quantified health and resource trade-offs associated with alternative HPV-based algorithms to inform decision-makers when choosing between candidate algorithms. METHODS: We used a mathematical simulation model of HPV-induced cervical carcinogenesis in Norway. We compared the current cytology-based strategy to alternative strategies that varied by the switching age to primary HPV testing (ages 25-34 years), the routine screening frequency (every 3-10 years), and management of HPV-positive, cytology-negative women...

Cervix carcinoma is the second commonest condition in women under 50 years of age and third after breast and oral cavity cancers across all age groups. Though a preventable disease, the mortality rate is very high because it is an ignored ailment in Pakistan in terms of screening, prevention and vaccination. More than 70% of cancer patients report with very advanced stage of malignancy and this is the cause of the high rate of mortality in Pakistan. We covered studies cited during the previous 11 years (2005-2015) that reviewed many aspects of cervical cancer in Pakistan, including epidemiology, risk factors, screening test and their barriers, clinical presentation and prevention...
