BACKGROUND: Human papillomavirus (HPV) testing based on cervical samples is important for use in cervical cancer screening. However, cervical sampling is invasive. Therefore, non-invasive methods for detecting HPV, such as urine samples, are needed. OBJECTIVES: For HPV detection in urine samples, two real-time PCR (RQ-PCR) tests, Roche cobas 4800 test (Roche_HPV; Roche Molecular Diagnostics) and Abbott RealTime High Risk HPV test (Abbott_HPV; Abbott Laboratories) were compared to standard cervical samples...

BACKGROUND: A significant number of women are diagnosed with minor cytological abnormalities on cervical screening. Many authorities recommend surveillance as spontaneous regression might occur. However, attendance for cytological follow-up decreases with time and might put some women at risk of developing invasive disease. OBJECTIVES: To assess the optimum management strategy for women with minor cervical cytological abnormalities (atypical squamous cells of undetermined significance - ASCUS or low-grade squamous intra-epithelial lesions - LSIL) at primary screening in the absence of HPV (human papillomavirus) DNA test...

OBJECTIVES: In addition to genotyping for HPV16/18, dual-immunostaining for p16/Ki-67 has shown promise as a triage of HPV-positive women. We assessed the performance of p16/Ki-67 dual-stained cytology for triaging HPV-positive women undergoing primary HPV screening. METHODS: All women ≥25years with valid cervical biopsy and cobas® HPV Test results from the cross-sectional phase of ATHENA who were referred to colposcopy (n=7727) were eligible for enrolment. p16/Ki-67 dual-stained cytology was retrospectively performed on residual cytologic material collected into a second liquid-based cytology vial during the ATHENA enrolment visit...

Cervical minimal deviation adenocarcinoma (MDA) is a rare variant of cervical adenocarcinoma that is difficult to diagnose due to the deep location, endogenous growth pattern, deceptively benign appearance of tumor cells, and lack of connection to human papillomavirus (HPV). Cytological evaluation and biopsies offer suboptimal detection and transvaginal sonography or Magnetic Resonance Imaging (MRI) only reveal multiple lesions that mimic multiple benign nabothian cysts. Besides, standard screening, diagnostic tools, and treatments are not established...

Altered interplay between gut mucosa and dysbiotic bacteria during HIV infection seems to fuel chronic immune dysfunction and might explain the excess rates of human papillomavirus (HPV)-associated anal cancer in HIV-infected individuals. Here, we show in HIV-infected MSM undergoing screening for HPV-related cancer that specific fecal and mucosal bacteria are able to predict the existence of precancerous anal lesions. If confirmed, these bacterial biomarkers could be exploited either as diagnostic tools or therapeutic targets...

BACKGROUND: HPV DNA diagnostic tests for epidemiology monitoring (research purpose) or cervical cancer screening (clinical purpose) have often been considered separately. Women with positive Linear Array (LA) polymerase chain reaction (PCR) research test results typically are neither informed nor referred for colposcopy. Recently, a sequential testing by using Hybrid Capture 2 (HC2) HPV clinical test as a triage before genotype by LA has been adopted for monitoring HPV infections. Also, HC2 has been reported as a more feasible screening approach for cervical cancer in low-resource countries...

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...

As China's population ages, the importance of determining prevalence of cervical disease and accurate cervical cancer screening strategies for postmenopausal women is increasing. Seventeen population-based studies were analyzed to determine prevalence of cervical neoplasia in postmenopausal women. All women underwent HPV DNA testing, visual inspection with acetic acid (VIA) and cytology testing. Diagnostic values for primary and combinations screening methods included sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), referral rate and area under curve (AUC) were calculated using directed biopsy or four quadrants biopsy as reference standard...

BACKGROUND: The Pap smear has remained the foundation for cervical cancer screening for over 70 years. With advancements in molecular diagnostics, primary high-risk human papillomavirus (hrHPV) screening has recently become an accepted stand-alone or co-test with conventional cytology. However, both diagnostic tests have distinct limitations. The aim of this study was to determine the association between HPV genotypes and cellular epigenetic modifications in three grades of cervical cytology for screening biomarker discovery...

Currently, clinical data for primary HPV screening alone are lacking in China. Here, we evaluate cervical cancer screening with primary HPV genotyping, as well as possible future screening strategy. Overall, high-risk HPV (hrHPV) prevalence was 18.2% among hospital-based population in Taizhou area. For cervical intraepithelial neoplasia 2 or worse (CIN2+), the sensitivity of primary hrHPV genotyping strategy and current cervical cancer screening strategy were 93.5%, and 71.1%, respectively; whereas the specificity was 17...

Mucosal infection by the human papillomavirus (HPV) is responsible for a growing number of malignancies, predominantly represented by cervical cancer and oropharyngeal squamous cell carcinoma. Because of the prevalence of the virus, persistence of infection, and long latency period, novel and low-cost methods are needed for effective population level screening and monitoring. We review established methods for screening of cervical and oral cancer as well as commercially-available techniques for detection of HPV DNA...

OBJECTIVE: A vast majority of cervicovaginal intraepithelial lesions are caused by high-risk human papillomaviruses (HPVs). The Pap test has been the sole method used for the screening of cervicovaginal squamous intraepithelial lesions (SIL). Recently, the FDA approved an HPV-DNA assay as a method of primary screening. We report on a series of FDA-approved HPV-DNA test-negative SIL with HPV genotyping, using an alternative method on the corresponding surgical biopsy specimens. STUDY DESIGN: A retrospective review identified cytology-positive HPV-negative cases over a 15-month period at a tertiary care gynecologic oncology institution...

Human papillomavirus (HPV) is a necessary cause of cervical cancer and its precursors. Increased expression of high-risk hrHPV viral oncogenes in abnormal cells might increase the expression of p16INK4a. We aimed to determine the role of p16INK4a in detecting hrHPV-transformed epithelial cells in liquid-based cervical cytology, and compared the results with hrHPV DNA testing by realtime polymerase chain reaction (RT-PCR). Fifty-seven cytological samples were tested for p16INK4a immunomarker and hrHPV DNA. Test performance of both tests was determined by comparing sensitivity, specificity and predictive values using available histological follow-up data as gold standard...

In the era of primary vaccination against HPV and at the beginning of the low prevalence of cervical lesions, introduction of screening methods that can distinguish between low- and high-grade lesions is necessary in order to maintain the positive predictive value of screening. This case-control study included 562 women who attended cervical screening or were referred for colposcopy and 140 disease free controls, confirmed by histology and/or cytology. The cases were stratified by age. Using routine exfoliated liquid based cytological samples RT-PCR measurements of biomarker genes, high-risk HPV testing and liquid based cytology were performed and used to evaluate different testing protocols including sets of genes/tests with different test cut-offs for the diagnostic panels...
