OBJECTIVE: Due to long lag time between infection/cancer diagnoses human papillomavirus (HPV) vaccination programs will deliver vaccine efficacy (VE) estimates against cancer end-points late. Cancer registry follow-up of population-based, randomised trial cohorts of vaccinated and unvaccinated women was undertaken for the estimation of VE against cervical intraepithelial neoplasia grade three and invasive cancer (CIN3+). METHODS: We report interim results with 98 561 person years of Finnish Cancer Registry -based follow-up of individually and/or cluster randomised cohorts of HPV-16/18 vaccinated and unvaccinated adolescent women enrolled in June 2003/2005, and between May 2004 and April 2005, respectively...

Objectives: Previous work in our laboratory identified keratin 17 (K17) as a specific and sensitive biomarker for high-grade squamous intraepithelial lesions and cervical squamous cell carcinoma (SCC). K17, however, has not been previously evaluated in endocervical glandular neoplasia. Based on the similar pathogenesis of squamous and glandular lesions of the cervix, we hypothesized that K17 overexpression could also be a diagnostic and/or prognostic biomarker for endocervical neoplasia...

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...

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: Cervical cancer disproportionately affects women from lower socioeconomic backgrounds. A human papillomavirus (HPV) vaccination programme was introduced in Scotland in 2008 with uptake being lower and inequitable in a catch-up cohort run for the first three years of the programme compared with the routine programme. The socioeconomic differences in vaccine uptake have the potential to further increase the inequality gap in regards to cervical disease. METHODS: Vaccination status was linked to demographic, cytological and colposcopic data, which are routinely collected by the Scottish HPV surveillance system...

OBJECTIVES: The quality of cervicovaginal smears determines the success of cytology in screening programs for cervical cancer. Bethesda 2014 revisited the adequacy criteria for atrophic smears and redefined the squamous cell count in the "unsatisfactory" category. In this study, we evaluated the smear quality of Thinprep liquid-based cervicovaginal Papanicolaou cytology slides (TPS) that were previously deemed unsatisfactory, to determine reasons for such categorization. In addition, we attempted to establish the impact of the new adequacy criteria on the rate and management of unsatisfactory diagnosis...

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...
