Background: Premenopausal risk-reducing salpingo-oophorectomy (RRSO) in women at high familial risk of ovarian cancer leads to immediate menopause. Although early natural menopause is associated with increased cardiovascular disease risk, evidence on long-term cardiovascular disease risk after early surgical menopause is scarce.

Objectives: We sought to determine the long-term influence of the timing of RRSO on the development of coronary artery calcium (CAC), an established marker for cardiovascular disease risk.

Article Synopsis
  • Risk-reducing salpingo-oophorectomy (RRSO) significantly lowers the risk of high-grade serous carcinoma (HGSC) in women carrying BRCA1/2 genetic variants, but some still develop HGSC after the procedure.
  • A study involving 2,519 women found that the 20-year cumulative incidence of HGSC was low (1.5% for BRCA1 and 0.2% for BRCA2 carriers), with particular risk factors identified, such as older age at RRSO and incomplete embedding of RRSO specimens.
  • Implementing strict guidelines for timely RRSO and ensuring complete specimen embedding could further minimize the risk of developing HGSC in these patients

Article Synopsis
  • - Mucosal melanoma (MucM) is a rare and aggressive form of cancer that responds poorly to immune checkpoint inhibition (ICI), especially when compared to cutaneous melanoma (CM).
  • - Analysis of 101 MucM tumors revealed lower levels of the immune marker IFN-γ and indicated that head and neck MucM had more immune cells and higher IFN-γ levels than MucM from other body sites.
  • - The study found that immune features differed across tumor locations, with immune-infiltrated tumors showing potential resistance mechanisms to ICI, highlighting the need for personalized treatment approaches for MucM.

Vulvar lichen sclerosus (LS) is an inflammatory dermatosis that can progress to human papillomavirus (HPV)-independent vulvar intraepithelial neoplasia (HPVi VIN) and vulvar squamous cell carcinoma (VSCC). Although LS has a much lower cancer risk compared with HPVi VIN (5% vs 50%, respectively), its incidence is significantly higher. Therefore, there is a clinical need to identify LS patients with an increased cancer risk.

Article Synopsis
  • Vulvar lichen sclerosus (LS) is a chronic inflammatory condition that can lead to serious complications like differentiated vulvar intraepithelial neoplasia (dVIN) and vulvar squamous cell carcinoma (VSCC), making its management critical especially post-surgery for VSCC.
  • A survey of 44 gynecologic oncologists in the Netherlands revealed that topical corticosteroids (TCS) are prescribed more frequently for LS patients without a history of VSCC compared to those following surgery for VSCC (86% vs. 52%).
  • Both patient groups are primarily treated with ultra-potent TCS for symptom relief and to prevent progression to serious conditions, though guidelines on post-surgery LS management remain unclear.

Article Synopsis
  • This study focuses on the accurate diagnosis of high-grade squamous intraepithelial lesions (HSIL) caused by HPV and HPV-independent vulvar intraepithelial neoplasia (VIN), highlighting the challenges in this area.
  • The research involved analyzing 751 patients with initially diagnosed high-grade VIN, using methods like histopathological reassessment and immunohistochemical testing, revealing that most lesions were HPV-associated and demonstrating significant differences in cancer risk between HPV-associated and HPV-independent cases.
  • The findings emphasize the importance of using p16 and p53 immunohistochemistry for accurate categorization of lesions, as HPV-independent VIN shows a much higher risk of cancer, especially in cases with mutant p53 patterns or nondifferenti

The precursor lesions of vulvar squamous cell carcinoma (VSCC) include human papillomavirus (HPV)-associated and HPV-independent squamous neoplasia with a varying cancer risk. Our study aimed to validate the accuracy of previously identified DNA methylation markers for detection of such high-grade vulvar intraepithelial neoplasia (VIN). A large clinical series of 751 vulvar lesions, originally diagnosed as high-grade VIN, were reassessed and categorized into HPV-associated or HPV-independent vulvar disease categories.

Background: Women with a BRCA1/2 pathogenic variant are advised to undergo premenopausal risk-reducing salpingo-oophorectomy after completion of childbearing, to reduce their risk of ovarian cancer. Several studies reported less sexual pleasure 1 to 3 years after a premenopausal oophorectomy. However, the long-term effects of premenopausal oophorectomy on sexual functioning are unknown.

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 vulvar squamous intraepithelial neoplasia, vulvar Paget disease in situ, and melanoma in situ. For differentiated vulvar intraepithelial neoplasia (dVIN), an excisional procedure must always be adopted. For vulvar high-grade squamous intraepithelial lesion (VHSIL), both excisional procedures and ablative ones can be used.

Background: Vulvar Paget disease is an extremely rare skin disorder, which is most common in postmenopausal women. Most vulvar Paget disease cases are noninvasive; however, it may be invasive or associated with an underlying vulvar or distant adenocarcinoma. The current treatment of choice for noninvasive vulvar Paget disease is wide local excision, which is challenging because of extensive intraepithelial spread and may cause severe morbidity.

Article Synopsis
  • The study focused on the cancer worries experienced by BRCA1 and BRCA2 pathogenic variant carriers undergoing surgery to reduce ovarian cancer risk, with a particular focus on identifying factors that contribute to high levels of worry.
  • Among the 577 participants, 57% reported high cancer worry before surgery, but 54% showed a decrease in worry 12 months post-surgery, with most classified into three distinct worry patterns.
  • Despite a general decline in worry, a small group (6%) experienced persistently high concerns, necessitating identification for potential additional support in their post-surgery journey.

Differentiated vulvar intraepithelial neoplasia (dVIN) is the precursor of human papillomavirus (HPV)-independent vulvar squamous cell carcinoma (VSCC). Given the rare incidence of dVIN, limited information on the exact cancer risk is available. We systematically reviewed the primary and recurrent VSCC risk in patients with dVIN, as well as the time to cancer development.

Objective: Risk-reducing surgery is advised to BRCA1/2 pathogenic variant (PV) carriers around the age of 40 years to reduce ovarian cancer risk. In the TUBA-study, a multicenter preference study (NCT02321228), BRCA1/2-PV carriers are offered a choice: the standard strategy of risk-reducing salpingo-oophorectomy or the novel strategy of risk-reducing salpingectomy with delayed oophorectomy. We evaluated feasibility and effectiveness of a patient decision aid for this choice.

Background: Usual vulvar intraepithelial neoplasia (uVIN) is a premalignancy caused by persistent infection with high-risk types of human papillomavirus (HPV), mainly type 16. Even though different treatment modalities are available (eg, surgical excision, laser evaporation or topical application of imiquimod), these treatments can be mutilating, patients often have recurrences and 2%-8% of patients develop vulvar carcinoma. Therefore, immunotherapeutic strategies targeting the pivotal oncogenic HPV proteins E6 and E7 are being explored to repress carcinogenesis.
