Cytologic-histologic correlation (CHC) represents a documented effort to obtain and compare, when available, gynecologic cytology reports with an interpretation of high-grade squamous intraepithelial lesion or malignancy, with the subsequent histopathology report, and to determine the possible cause of any discrepancy. The correlation is influenced by multiple closely interdependent clinical and pathologic factors. Many of these factors including the sensitivity and accuracy of colposcopy-directed biopsy, the diligence of the colposcopist, and the attributes of the cervical lesion represent "preanalytical" factors which can significantly affect the CHC outcome, but are often less emphasized during CHC process...

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...

An asymptomatic 24-year-old woman underwent a colposcopy, cervical biopsy, and subsequently, a conization for a cervical squamous cell carcinoma in situ with glandular extension. Simultaneously, an endometrial biopsy was carried out in which, incidentally, a placental site nodule was diagnosed, a rare non-neoplastic lesion originating in the intermediate trophoblast. Given the coexistence of these two entities, it was necessary to make a differential diagnosis between them and also with other pathologies of the trophoblast such as an exaggerated placental site, placental site trophoblastic tumor, and epithelioid trophoblastic tumor...

BACKGROUND: Polymerase chain reaction-based Xpert human papillomavirus (HPV) assay is a rapid test that detects high-risk HPV (hrHPV) infection. This point-of-care test is usually performed by collecting a cervical specimen in a vial of PreservCyt® transport medium. We compared HPV test positivity and accuracy between self-collected sample with a dry swab (s-DRY) versus physician-collected cervical sampling using a broom like brush and immediate immersion in PreservCyt (dr-WET). METHODS: In this cross-sectional study, we recruited 150 women ≥ 18 years old attending the colposcopy clinic in the University Hospital of Geneva...

Efforts have been being made to improve the diagnostic performance of colposcopy, trying to help better diagnose cervical cancer, particularly in developing countries. However, improvements in a number of areas are still necessary, such as the time it takes to process the full digital image of the cervix, the performance of the computing systems used to identify different kinds of tissues, and biopsy sampling. In this paper, we explore three different, well-known automatic classification methods (k-Nearest Neighbors, Naïve Bayes, and C4...

HPV-based screening provides greater protection against cervical cancer (CC) than cytology-based strategies. Currently, several molecular diagnostic assays for the detection of human papillomavirus (HPV) are available. In this study, we analyzed 5 different HPV testing and genotyping techniques (Hybrid Capture 2 [HC2; Qiagen, Hilden, Germany], AnyplexTMII HPV28 [Anyplex; Seegene, Seoul, Korea], Linear Array [Roche, Branchburg, NJ, USA], GP5+/6+ PCR-EIA-RH [Labo Bio-medical Products, Rijswijk, The Netherlands] and CLART2 [Genomica, Madrid, Spain]) in 295 women referred to the hospital Colposcopy Clinic from 2007 to 2008 due to positive HPV test results or an abnormal Pap test...

In 2015, Cold Coagulation was introduced as a treatment for cervical intraepithelial neoplasia (CIN) at our colposcopy clinic. We reviewed the 6-month follow up data of the first 200 women who underwent Cold Coagulation using cytology and HPV status as tests of cure (TOC). A random sample of 200 patients treated by Large Loop Excision of the Transformation Zone (LLETZ) during the same period was used to compare treatment outcome. Six months following treatment,173 (86.5%) of the women treated by CC and 167 (83...

This study evaluates the suitability of Xpert HPV (Cepheid, Sunnyvale, CA, USA) test for cervical and tonsillar formalin-fixed paraffin-embedded (FFPE) tissue samples as compared to the tests currently used in diagnostics. Cervical biopsies and liquid cytology (LC) samples were collected from 48 women attending colposcopy. Biopsies were processed for histology and tested for hrHPV using Xpert HPV. LC samples were tested using Xpert and Hybrid Capture 2 (HC2; Qiagen, Hilden, Germany) tests. Also 29 archived tonsillar carcinoma samples were tested using Xpert, and the results were compared with histology and immunohistochemical p16INK4a (p16) staining...

p16÷Ki-67 dual-stained cytology, either alone or combined with human papillomavirus (HPV) 16÷18 genotyping, could be a useful tool for triage for colposcopy of HPV-positive patients. Based on this background, we aimed at comparing the diagnostic performance of the p16÷Ki-67 dual staining test, and high-risk HPV test for the detection of high-risk cervical intraepithelial neoplasia (CIN2÷3) in patients diagnosed with low-grade squamous intraepithelial lesion (LSIL) on Pap smear. We performed a retrospective study including 184 patients with LSIL cytology on Pap smear, of which 64 were referred for biopsy after colposcopy...

Objective: To investigate the clinical value of p16/Ki-67 immunocytochemistry in patients with atypical squamous cells of undetermined significance(ASC-US). Methods: One hundred and seventy-one cases of thin-prep cytology test (TCT) diagnosed as ASC-US underwent p16/Ki-67 immunocytochemistry. All patients had colposcopy and biopsy from March 2015 to January 2016. Ninety of the 171 cases underwent high-risk HPV test at the same time. Results: p16/Ki-67 immunocytochemistry was positive in 43.9% (75/171) of the 171 cytology samples; the sensitivity and specificity of p16/Ki-67 immunocytochemistry were 77...

SurePath specimens from women referred to colposcopy were treated with Aptima Transfer Solution (ATS) before testing in Aptima HPV (AHPV) and Aptima HPV 16, 18/45 (AHPV-GT) assays. Untreated SurePath specimens were tested with the cobas HPV test. PreservCyt specimens were assessed for cytology and tested with AHPV. High-grade cervical intraepithelial neoplasia lesions served as the reference standard. Excellent agreement (95.5%; k=0.91) was observed for ATS-treated SurePath specimens between Tigris and Panther systems and between the PreservCyt and ATS-treated SurePath specimens (91...
