INTRODUCTION: Recurrent cervical intraepithelial lesions (rCIN2/3) after treatment of CIN2/3 occur in 5-15% of cases. rCIN2/3 can result from incomplete resection of CIN2/3, where the same HPV type and variant remains present. rCIN2/3 could also occur following a new infection with a different HPV variant of the same HPV type as the initial lesion. This study investigates HPV16 consensus variants in paired HPV16 positive scrapes from baseline CIN2/3 and rCIN2/3 lesions. METHODS: Paired HPV16 positive cervical scrapes of women with CIN2/3 at baseline and rCIN2/3 6 or 12 months after treatment were selected for whole-genome amplification and Illumina sequencing...

The Papanicolaou (PAP) test is widely used to screen for cervical cancer. All high-grade lesions such as atypical squamous cells, cannot exclude high-grade squamous intraepithelial lesion (ASC-H), and high-grade squamous intraepithelial lesion, identified on a PAP test should be followed-up by a confirmatory cervical biopsy. In this review, we discuss the challenges in interpreting cervical tissue specimens and the various ancillary techniques used in the evaluation of cervical dysplasia. Ancillary studies include deeper levels, p16 immunohistochemistry (IHC), human papillomavirus (HPV) testing, and, importantly, cyto-histologic correlation...

Primary prevention through the use of human papillomavirus (HPV) vaccination is expected to impact both cervical intraepithelial neoplasia (CIN) and adenocarcinoma in situ (AIS). While CIN is well described, less is known about the epidemiology of AIS, a rare cervical precancer. We identified AIS and CIN grade 3 (CIN3) cases through population-based surveillance, and analyzed data on HPV types and incidence trends overall, and among women screened for cervical cancer. From 2008-2015, 470 AIS and 6,587 CIN3 cases were identified...

AIM: In Cambodia, the Japan Society of Obstetrics and Gynecology and the Cambodian Society of Gynecology and Obstetrics have an on-going project, started in 2015, for cervical cancer prevention and treatment. The project, currently aimed at factory workers, includes a women's health education program that leads into cervical cancer prevention by establishment of a system for early detection and treatment. It begins by health education, screening for human papillomavirus (HPV), followed by colposcopy and quicker treatment of earlier precursor lesions...

p63 is a transcription factor p53 family. Two major isoforms of p63, TAp63 with transactivation (TA) domain and ΔNp63 with truncated TA domain, have been reported to play opposing roles either in tumor suppression or oncogenic function. Little is known about the association of these two isoforms of p63 in the carcinogenesis of cervical cancer. In this study, the mRNA expression levels of TAp63 and ΔNp63 in 40 normal, 30 low-grade squamous intraepithelial lesions (LSIL), 38 high-grade squamous intraepithelial lesions (HSIL), and 52 cervical cancer formalin-fixed paraffin-embedded tissues were examined using quantitative reverse transcription polymerase chain reaction (RT-qPCR)...

Cervical screening by high-risk HPV (hrHPV) testing requires additional risk stratification (triage), as most infections are transient and only a subset of hrHPV-positive women harbours clinically relevant disease. Molecular triage markers such as microRNAs (miRNAs) and DNA methylation markers are particularly promising, as they can be objectively tested directly on hrHPV-positive scrapes and cervicovaginal self-samples. Here, we evaluated the marker potential of 10 candidate miRNAs in 209 hrHPV-positive scrapes of women with underlying precancer (cervical intraepithelial neoplasia, grade 2-3 (CIN2-3)), cancer, or without disease (CIN0/1)...

Cervical cancer is a major worldwide health problem. Therefore, regular cervical screening in order to make an early diagnosis can help to prevent cervical cancer, through identifying and treating preinvasive cervical lesions. The aim of this review is to evaluate the correlation between the cytological screening result and the final gold standard histological outcome in the diagnosis of cervical lesions. More specifically, the correlation between high-grade intraepithelial lesion (HSIL) on cytology and histological cervical intraepithelial neoplasia grade 2 or higher (CIN2+) was intended, by calculating the positive predictive value (PPV)...

Introduction: Cervical erosion and squamouse intraepithelial lesion of low grade are most common gynecological problems of women. These changes on cervix are cause of painful coitus and enhanced vaginal secretion. Cryotherapy is widely accepted method in treating these changes and sympthoms. Aim: The aim of this study is to examine the efficiency of cryotherapy in eliminating erosion of cervics and LSIL, as well as conditions following these states. Patients and methods: Cryotherapy was performed in 124 women with cervical erosion (N-74) and LSIL (N-50)...

Human papillomavirus (HPV) causes cervical cancer, anal cancer, vulvar cancer, vaginal cancer, penile cancer and oropharyngeal cancer. SCC in the genital region in particular is recognized to be caused by HPV infection, and intraepithelial lesions of the penis and vulva are termed penile intraepithelial neoplasia (PIN) and vulvar intraepithelial neoplasia (VIN), respectively. Although SCC of the nail apparatus is recognized as being associated with high-risk HPVs, it is not well-known in general medicine, and its analysis has been insufficient...

INTRODUCTION: There is no national cervical screening program or national standards for cervical cytology quality control in China. Since 2013, systematic training and quality control programs were implemented in the Papanicolaou testing process at Jinan KingMed Diagnostics. Pathologists were required to complete 1 year of cytology study in the KingMed Diagnostics Cytology School, including 6 months of a diagnostic course and 6 months of practical training in the clinical laboratory. In this study, we compared the Papanicolaou abnormal reporting rates before and after the implementation systematic training and quality control programs...

BACKGROUND: Current automated cervical cytology screening systems still heavily depend on manipulation of glass slides. We developed a new system called CytoProcessorTM (DATEXIM, Caen, France), which increases sensitivity and takes advantage of virtual slide technology to simplify the workflow and save worker time. We used an approach based on artificial intelligence to identify abnormal cells among the tens of thousands in a cervical preparation. OBJECTIVES: We set out to compare the diagnostic sensitivity and specificity of CytoProcessorTM and the ThinPrep Imaging System (HOLOGIC, Marlborough, MA, USA)...

Ghana does not have a universal population-based cervical cancer screening program and there is very limited information about the distribution of cervical epithelial cell lesions. This study provides evidence that a moderately high prevalence of cervical cancer and precancerous lesions exists among unscreened women in Kumasi.The prevalence of cervical epithelial cell abnormalities among a cross-section of women attending cervical cancer screening for the first time in a suburb of Ghana from 2011 to 2014 was studied...

Background: Vasculogenic mimicry (VM), as an endothelium-independent cancer microcirculation, has been observed in many malignancies including cervical cancer. Erythropoietin (EPO) and erythropoietin receptor (EPO-R) could produce an angiogenic effect to promote cervical squamous cell carcinoma (CSCC) progression. However, the association between VM formation and EPO/EPO-R expression in CSCC is poorly explored. Methods: Seventy-six paraffin-embedded CSCC samples, 25 high-grade squamous intraepithelial lesion (HSIL) samples, 20 low-grade squamous intraepithelial lesion (LSIL) samples, and 20 normal cervix samples were collected...

EXECUTIVE SUMMARY: The risk of cervical cancer (CC) among women immunosuppressed for a variety of reasons is well documented in the literature. Although there is improved organ function, quality of life and life expectancy gained through use of immunosuppressant therapy, there may be increased long-term risk of cervical neoplasia and cancer and the need for more intense screening, surveillance, and management. Although guidance for CC screening among HIV-infected women (see Table 1) has been supported by evidence from retrospective and prospective studies, recommendations for CC screening among non-HIV immunosuppressed women remains limited because quality evidence is lacking...

BACKGROUND: A reduced, two-dose schedule of human papillomavirus (HPV) vaccination has been endorsed for preadolescent women on the basis of immunogenicity data from randomised trials, and limited data suggest even one dose may provide sufficient protection. Surveillance of the impact of fewer than three vaccine doses on clinical endpoints in the targeted age group is warranted.
