The European Society of Gynaecological Oncology (ESGO), the International Society for the Study of Vulvovaginal Disease (ISSVD), the European College for the Study of Vulval Disease (ECSVD), and the European Federation for Colposcopy (EFC) Consensus Statement on the Management of Vaginal Intraepithelial Neoplasia

Abstract The European Society of Gynaecological Oncology (ESGO), the International Society for the Study of Vulvovaginal Disease (ISSVD), the European College for the Study of Vulval Disease (ECSVD), and the European Federation for Colposcopy (EFC) developed consensus statements on pre-invasive vulvar lesions in order to improve the quality of care for patients with vaginal intraepithelial neoplasia (VaIN). The management of VaIN varies according to the grade of the lesion: VaIN 1 (low grade vaginal squamous intraepithelial lesions (SIL)) can be subjected to follow-up, while VaIN 2–3 (high-grade vaginal SIL) should be treated. Treatment needs individualization according to the patient’s characteristics, disease extension and previous therapeutic procedures. Surgical excision is the mainstay of treatment and should be performed if invasion cannot be excluded. Total vaginectomy is used only in highly selected cases of extensive and persistent disease. Carbon dioxide (CO2) laser may be used as both an ablation method and an excisional one. Reported cure rates after laser excision and laser ablation are similar. Topical agents are useful for persistent, multifocal lesions or for patients who cannot undergo surgical treatment. Imiquimod was associated with the lowest recurrence rate, highest human papillomavirus (HPV) clearance, and can be considered the best topical approach. Trichloroacetic acid and 5-fluorouracil are historical options and should be discouraged. For VaIN after hysterectomy for cervical intraepithelial neoplasia (CIN) 3, laser vaporization and topical agents are not the best options, since they cannot reach epithelium buried in the vaginal scar. In these cases surgical options are preferable. Brachytherapy has a high overall success rate but due to late side effects should be reserved for poor surgical candidates, having multifocal disease, and with failed prior treatments. VaIN tends to recur and ensuring patient adherence to close follow-up visits is of the utmost importance. The first evaluation should be performed at 6 months with cytology and an HPV test during 2 years and annually thereafter. The implementation of vaccination against HPV infection is expected to contribute to the prevention of VaIN and thus cancer of the vagina. The effects of treatment can have an impact on quality of life and result in psychological and psychosexual issues which should be addressed. Patients with VaIN need clear and up-to-date information on a range of treatment options including risks and benefits, as well as the need for follow-up and the risk of recurrence.

Evaluation of Host Gene Methylation as a Triage Test for HPV-Positive Women—A Cohort Study

Objectives This study was designed to evaluate the performance of a host gene methylation marker panel (ASTN1, DLX1, ITGA4, RXFP3, SOX17, and ZNF671) in the triage of human papillomavirus (HPV)-positive women, its possible impact in a cervical cancer screening program, and the possible influence of the variation of the rate of HPV16/18 in its performance. Materials and Methods Cohort study in which consecutive women referred for colposcopy in an organized cervical cancer screening program had repeated HPV testing, colposcopy, and biopsies. The women that remained HPV positive at the time of colposcopy were tested with the panel of DNA methylation markers. The performance of the test was evaluated and compared to standard practice. Results The study test had a sensitivity and specificity for cervical intraepithelial neoplasia (CIN) 2+ of 60.8% (49.1–71.6%) and 88.4% (83.2–92.5%), respectively. For CIN3+, it was of 78.0% (64.0–88.5%) and 86.0% (80.8–90.2%), respectively. The rate and level of methylation positively correlated with the severity of disease. The use of methylation reduces the referral for colposcopy to 25.5%, while detecting 78.0% of the CIN3+ cases. Referral of all HPV16/18-positive cases and triage of the other high-risk HPV-positive cases with methylation, detects 90.0% of the cases of CIN3+, while reducing the number of referrals to 43.2%. The variation in the rate of HPV16/18 does not relevantly affect the performance of the methylation panel. Conclusions The studied methylation panel has a high sensitivity and specificity for CIN3+ and reduces the rate of referrals for colposcopy, without relevant variation according to the rate of HPV16/18.

Vulvar inspection at the time of cervical cancer screening: European Society of Gynaecological Oncology (ESGO), International Society for the Study of Vulvovaginal Disease (ISSVD), European College for the Study of Vulval Disease (ECSVD), and European Federation for Colposcopy (EFC) consensus statements

Vulvar squamous cell carcinoma incidence is increasing, especially among women under 60, largely attributed to human papillomavirus infections. Precursor pre-invasive vulvar lesions are frequently underdiagnosed. Routine vulvar inspection during cervical cancer screening could offer an opportunity for the detection of these lesions. To emphasize the importance of integrating routine vulvar inspection during cervical cancer screening procedures and to raise awareness about the early detection of vulvar squamous cell carcinoma and its precursors to reduce the diagnostic delay of vulvar pathologies. A multidisciplinary task force comprising experts from 4 international scientific societies was formed. A focused literature review was conducted, and consensus statements were developed through a structured voting process to ensure clinical relevance and comprehensiveness. The consensus defines key elements of normal vulvar anatomy, identifies potential pre-cancerous dermatoses, and highlights risk factors for vulvar malignancy. The consensus statements promote the integration of vulvar inspection into cervical cancer screening procedures, urging health care professionals across various levels to receive training and guidance in vulvar examinations and enhancing patient education. Health care providers are recommended to gather a brief history of vulvar symptoms, conduct comprehensive inspections of the vulvar area, and report any abnormalities. For patients with positive human papillomavirus or Pap tests, they should closely monitor vulvar findings, encourage self-examinations, and discuss risks for intra-epithelial or invasive neoplasia. Establishing standardized practices in vulvar inspection during cervical cancer screening procedures along with public awareness, could significantly impact early detection and timely interventions of vulvar pathologies at cancer risk ultimately reducing the burden of vulvar cancers.
