Objectives: Vulvar squamous cell carcinoma (VSCC) is a rare malignant disease but with increasing incidence. Therapeutic options are generally limited to surgery and radio-(chemo)therapy. New strategies for therapy are lacking.

Background/aim: Cervical intraepithelial neoplasia (CIN) III/high-grade squamous lesions (HSIL) remains a significant challenge during pregnancy. Current data on the course of disease are contradictory, with cases of progression to cervical cancer (CC) during pregnancy being observed. Evidence suggests that the expression of L1 capsid protein is associated with a favorable prognosis in non-pregnant women.

Background: Squamous cell vulvar carcinoma is a rare malignant disease of women. In higher tumor stages survival rates are poor. Therapy options are limited.

Purpose: In 2018, the first guideline-based quality indicators (QI) for vulvar cancer were implemented in the data-sheets of certified gynaecological cancer centres. The certification process includes guideline-based QIs as a fundamental component. These indicators are specifically designed to evaluate the level of care provided within the centres.

Background/aim: The global impact of the COVID-19 pandemic resulted in disruptions to healthcare systems throughout the world. The numbers of cytology examinations, human papillomavirus (HPV) tests, and women referred for colposcopy decreased in many countries. There have been no reports on cervical cancer screening in Germany.

Purpose: In 2008, the first gynecological cancer centres were certified by the German Cancer Society (DKG). Guideline-based quality Indicators (QIs) are a core element of the certification process. These QI are defined to assess the quality of care within the centres and can serve to measure the implementation of guideline recommendation.

Background/aim: The aims of the present study were to evaluate the accuracy of colposcopic findings, investigate the way in which untreated cervical intraepithelial neoplasia (CIN) 2/3 develops during pregnancy, and identify factors associated with regression, persistence, or progression rates.

Patients And Methods: In a tertiary gynecology and obstetrics department, 655 pregnant women were seen for colposcopy. The most common reason for referral was abnormal cytology findings.

Purpose: The aims of the present study were to evaluate the development of untreated cervical intraepithelial neoplasia (CIN) 3 during pregnancy and to assess persistence, progression, and regression rates postpartum to identify factors associated with regression.

Methods: In a tertiary gynecology and obstetrics department, a total of 154 pregnant women with CIN 3 were treated in the dysplasia unit. The follow-up findings were analyzed retrospectively on the basis of histological, cytological, and human papillomavirus (HPV) testing of 154 pregnant women confirmed as having CIN 3 in colposcopically guided biopsies.

Article Synopsis
  • Cervical cancer is primarily caused by persistent infections with high-risk human papillomavirus (hrHPV), and this study looked at how different hrHPV types relate to age and their association with cervical cancer and its precursor lesions.
  • The research analyzed HPV samples from 652 women, finding that 30.8% were HPV-negative, with HPV-16 being the most prevalent among HPV-positive cases, especially in younger women with high-grade lesions.
  • The study concluded that while HPV-16 is frequently seen in younger women (≤ 34 years), its prevalence decreases with age, highlighting the need for careful monitoring of women aged ≥ 35 who have persistent hrHPV infections due to their increased risk for developing cervical cancer.

Article Synopsis
  • The study assesses how well clinical findings align with colposcopy-directed punch biopsy results for diagnosing vulvar diseases.
  • Out of 482 biopsies from 420 women, the overall concordance rate between clinical observations and biopsy results was 53.9%, with higher concordance for detecting low and high-grade lesions, as well as vulvar carcinoma.
  • Researchers introduced a new classification system to improve the accuracy and specificity of diagnosing vulvar lesions based on their findings.

Purpose: Malignancies of the vagina are rare, but colposcopy-directed biopsies play a major role in detecting vaginal intraepithelial lesions. Data of accuracy in detecting neoplasia of the vagina are very rare compared to accuracy in detecting cervical neoplasia. The aim of this study was to evaluate the accuracy of colposcopy-directed biopsy in comparison with clinical findings of the examiner.

Purpose: Colposcopy-directed biopsy is a cornerstone method for diagnosing cervical intraepithelial neoplasia. The aim of this study was to evaluate the accuracy of colposcopy-directed biopsy in comparison with definitive surgery.

Methods: The accuracy of colposcopy-directed biopsy was compared with the final histology in relation to different types of transformation zone (TZ), the patient's age, and the examiner's level of training.
