To assess the excess risk of HPV-associated cancer (HPVaC) in two at-risk groups - women with a previous diagnosis of high grade cervical intraepithelial neoplasia (CIN3) and both men and women treated for non-cervical pre-invasive ano-genital disease. All CIN3 cases diagnosed in 1989-2015 in Scotland were extracted from the Scottish cancer registry (SMR06). All cases of pre-invasive penile, anal, vulval, and vaginal disease diagnosed in 1990-2015 were identified within the NHS pathology databases in the two largest NHS health boards in Scotland...

Objectives: To determine the BD Onclarity human papillomavirus (HPV) assay performance and risk values for cervical intraepithelial neoplasia grade 2 (CIN2) or higher and cervical intraepithelial neoplasia grade 3 (CIN3) or higher during Papanicolaou/HPV cotesting in a negative for intraepithelial lesions or malignancies (NILM) population. Methods: In total, 22,383 of the 33,858 enrolled women were 30 years or older with NILM cytology. HPV+ and a subset of HPV- patients (3,219/33,858 combined; 9...

Background: Even though cervico-vaginal smears have been used as a primary screening test for cervical carcinoma, the diagnostic accuracy has been controversial. The present study aimed to evaluate the diagnostic accuracy of cytology for squamous intraepithelial lesion (SIL) and squamous cell carcinoma (SqCC) of the uterine cervix through a diagnostic test accuracy (DTA) review. Methods: A DTA review was performed using 38 eligible studies that showed concordance between cytology and histology...

It is valuable to establish a population-based prevaccination baseline distribution of human papillomavirus (HPV) types among women with high-grade cervical intraepithelial neoplasia (CIN) grade 2 or 3 and cervical cancer in order to assess the potential impact of HPV vaccination. In four countries (Denmark, Norway, Sweden, and Iceland), we collected consecutive series of cervical cancers (n = 639) and high-grade precancerous cervical lesions (n = 1240) during 2004-2006 before implementation of HPV vaccination and subjected the specimens to standardized HPV genotyping...

BACKGROUND: Persistent infection with high-risk genotypes of human papillomavirus (HPV) is the main risk factor in the development of uterine cervical precancerous lesions and cervical cancer (CC), and cases of HPV-induced oropharyngeal squamous cell carcinoma (OPSCC) is increasing in the Western world. We investigated the association between HPV and p16 status and previous results of cervical examinations, including cytological and histological tests, in females with OPSCC. MATERIAL AND METHODS: We included females diagnosed with an OPSCC in Eastern Denmark from 2000 to 2014...

Cervical cancer is the fourth most common malignancy affecting women worldwide. The development of disease is related to high-risk human papillomavirus (hrHPV) infection. Cytology has been the most recommended triage for primary cervical (pre)cancer screening despite relatively low sensitivity. Recently, genomic DNA methylation has been proposed as an additional marker to increase sensitivity for detecting cervical precancerous lesion. This study aimed to evaluate the performance of methylation status of three tumor suppressor genes (CADM1, FAM19A4, and MAL) and HPV genotyping in detection of cytologic and histologic abnormalities in cervical cancer screening...

OBJECTIVE: Ultrahigh-resolution optical coherence microscopy (OCM) has recently demonstrated its potential for accurate diagnosis of human cervical diseases. One major challenge for clinical adoption, however, is the steep learning curve clinicians need to overcome to interpret OCM images. Developing an intelligent technique for computer-aided diagnosis (CADx) to accurately interpret OCM images will facilitate clinical adoption of the technology and improve patient care. METHODS: 497 high-resolution 3-D OCM volumes (600 cross-sectional images each) were collected from 159 ex vivo specimens of 92 female patients...

Background: Cervical cancer is caused by persistent human papillomavirus (HPV) infection. US consensus management guidelines for a positive cervical screening result typically focus on the current screening result only. A negative testing history may alter risk of the following positive screening results, caused by a new HPV infection, and therefore its optimal management. Methods: Women ages 30 years and older were screened with triennial HPV and cytology co-testing at Kaiser Permanente Northern California from 2003 to 2014...

High-grade cervical intraepithelial neoplasia (CIN) is a precancerous lesion of cervical cancer. The aims of this study were to evaluate the risk factors for recurrence of high-grade CIN and to determine if the specific genotype of human papillomavirus (HPV) is a predictor of recurrent high-grade CIN. Between January 2010 and December 2014, 172 patients with CIN 2+ underwent cold knife conization or a loop electrosurgical excision. The HPV DNA chip was used to detect HPV. Recurrent lesions were histologically confirmed and considered to be recurrence of CIN2+...

Cervical cancer (CC) is the second most common type of cancer affecting the female population. The development of CC takes several years, and involves a precancerous stage known as cervical intraepithelial neoplasia (CIN). A key factor in the development of disease is the human papillomavirus (HPV) infection, which initiates carcinogenesis. Furthermore, CC is also impacted by epigenetic changes such as DNA methylation, which causes activation or exclusion of certain genes, and the hypermethylation of cytosines in promoters, thereby switching off previously active genes...
