Objective: Several European and American guidelines recommend to perform an additional hysterectomy in patients with cervical adenocarcinoma in situ (AIS), who initially received conservative treatment and who completed childbearing during follow-up. This study aimed to evaluate cost-effectiveness of performing an additional hysterectomy in comparison to expectative management.

Methods: This post-hoc analysis was based on a retrospective cohort of patients diagnosed with AIS, who were conservatively treated by a radical (i.

DNA methylation of host-cell genes is an epigenetic process that regulates gene expression and is associated with cervical cancer development. Studies on the natural history of cervical intraepithelial neoplasia (CIN) and the molecular alterations associated with cervical carcinogenesis led to the identification of several host-cell DNA methylation markers. Over the past years, various studies on methylation markers have shown promising results in terms of diagnostic and prognostic value to improve cervical cancer screening and management of CIN.

High-risk HPV (hrHPV)-based screening has led to many unnecessary colposcopy referrals, mainly because of direct referral after low-grade cytology (ASC-US/LSIL). DNA methylation and genotyping tests on ASC-US/LSIL samples have the potential to significantly improve the efficiency of screening. In this study, 12 triage strategies were constructed from FAM19A4/miR124-2 or ASCL1/LHX8 methylation, HPV16/18 or HPV16/18/31/33/45 genotyping and 1-year repeat cytology.

Background: Recently, the immunohistochemical markers cytokeratin 17 (CK17) and SRY-box2 (SOX2) have been evaluated as adjuncts for the diagnosis of high-grade vulvar intraepithelial neoplasia (VIN). In the present study, the aim was to assess CK17 and SOX2 expression in VIN by studying 150 vulvar lesions, originally reported as high-grade VIN and to assess the diagnostic accuracy.

Methods: All slides (H&E, p16, p53, Ki-67, CK17, and SOX2 stains) were independently assessed by six pathologists and the final diagnosis was reached in consensus meetings, as follows: 46 human papillomavirus (HPV)-independent VIN (including 30 p53 mutant and 16 p53 wild-type lesions), 58 high-grade squamous intraepithelial lesions (HSILs), 4 low-grade SILs (LSILs), 37 non-dysplastic lesions, and 5 lesions where the histology was inconclusive.

Objective: To systematically explore vulvar pathology diagnosed prior to vulvar squamous cell carcinoma (VSCC), as well as the association with tumor characteristics, stage and survival outcome, with the aim of improving vulvar cancer prevention strategies.

Methods: VSCC diagnosed between 2005 and 2019 were identified from a population-based cohort provided by the Dutch Nationwide Pathology Databank. Pathology reports were reviewed to identify vulvar pathology diagnosed before primary VSCC.
