The risk of developing squamous cell carcinoma in patients with anogenital lichen sclerosis: A systematic review.

INTRODUCTION: Lichen sclerosis (LS) is a chronic inflammatory skin disease, mostly affecting the anogenital region. Patients with LS have a higher risk of developing anogenital squamous cell carcinoma (SCC), although exact numbers are not known. OBJECTIVE: To systematically review the absolute risk (AR) and incidence rate (IR) of developing SCC in patients with anogenital LS, as well as patient characteristics that influence the risk of developing LS associated SCC. METHODS: A search was performed through the databases of Pubmed and Embase. Five reviewers independently screened the articles on title/abstract and full text published before 31st of July 2019. The selected articles were critically appraised using the Quality In Prognostic Studies tool. RESULTS: Of 2238 titles and abstracts assessed, 15 studies were selected to be analysed. The AR of developing SCC in patients with LS varied between 0.21 and 3.88% for women and 0.00-0.91% for men across the included studies. The IR was 0.65-8.89/1000 person-years for women and 0.00-6.49/1000 person-years for men. This risk for women seemed to be increased by age, the presence of vulval intra-epithelial neoplasia (VIN), a long history of LS, late diagnosis of LS and partial compliance of treatment with topical corticosteroids. For men, no determinants were found. CONCLUSION: We found fair evidence that the AR of developing SCC in patients with anogenital LS varied between 0.21 and 3.88% for women and 0.00-0.91% for men. Therefore, we recommend regular follow up and compliant treatment with topical corticosteroids, especially in older women.

Changes in Sex Steroids and Relation With Menopausal Complaints in Women Undergoing Risk-reducing Salpingo-oophorectomy.

Context: Risk-reducing salpingo-oophorectomy (RRSO) is performed in BRCA1 or 2 mutant carriers to minimize ovarian cancer risk. Although studies have been performed investigating sex steroid levels, menopausal complaints, and sexual functioning in relation to RRSO, their exact relationship remains unknown. Objectives: To investigate the impact of RRSO on serum sex steroid levels and their association with menopausal complaints and sexual functioning. Methods: This prospective observational cohort study included 57 premenopausal and 37 postmenopausal women at risk of ovarian cancer and opting for RRSO. Data collection involved validated questionnaires on sexual functioning and menopausal complaints. Testosterone, androstenedione, estradiol, and estrone levels in serum determined by liquid chromatography-tandem mass spectrometry were obtained 1 day before, 6 weeks, and 7 months after RRSO. Results: In premenopausal women, all 4 steroids were decreased both 6 weeks (P < 0.01) and 7 months (P < 0.01) after RRSO. Furthermore, in these women, decreases in estrogens were associated with a decrease in sexual functioning 7 months after RRSO (P < 0.05). In postmenopausal women, only testosterone was decreased 6 weeks and 7 months (P < 0.05) after RRSO, which was associated with an increase in menopausal complaints at 7 months post-RRSO (P < 0.05). Conclusion: Our results suggest that in premenopausal women, decreases in estrogens are related to a decrease in sexual functioning and that in postmenopausal women, testosterone is decreased after RRSO, which indicates that postmenopausal ovaries maintain some testosterone production. Furthermore, in postmenopausal women, a large decrease of testosterone was associated with more menopausal complaints, indicating that future studies investigating testosterone supplementation are warranted.

The Vulvar Cancer Risk in Differentiated Vulvar Intraepithelial Neoplasia: A Systematic Review.

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. A systematic search was performed up to July 2021 according to the PRISMA guidelines. Five reviewers independently screened articles on title, abstract and full text, followed by critical appraisal of selected articles using the Quality in Prognostic Studies (QUIPS) tool. Of the 455 screened articles, 7 were included for analysis. The absolute risk for primary VSCC in dVIN varied between 33 and 86%, with a median time to progression to VSCC of 9-23 months. The risk of developing recurrent VSCC in dVIN associated VSCC was 32-94%, with a median time to recurrence of 13-32 months. In conclusion, patients with dVIN have a high risk of developing primary and recurrent VSCC with a short time to cancer progression. Increased awareness, timely recognition, aggressive treatment and close follow-up of HPV-independent vulvar conditions including dVIN is therefore strongly recommended.

Hormone replacement therapy after risk-reducing salpingo-oophorectomy minimises endocrine and sexual problems: A prospective study.

BACKGROUND: There has been some doubts raised in earlier studies about the efficacy of hormone replacement therapy (HRT) in reducing endocrine and sexual problems in women who have undergone a risk-reducing salpingo-oophorectomy (RRSO). METHODS: In this prospective, observational study, we recruited 178 premenopausal women with a high risk for ovarian cancer. Fifty-seven women opted for RRSO and 121 for gynaecological screening (GS). Women completed questionnaires before surgery (T1) and 3 (T2) and 9 (T3) months post surgery, or at equivalent time points for the GS-group. Menopausal symptoms were assessed with the Functional Assessment of Cancer Therapy-Endocrine Subscale (FACT-ES) and sexual functioning with the Sexual Activity Questionnaire (SAQ). Groups were compared using repeated measures mixed effect models for continuous variables, and generalised estimating equations for longitudinal ordered categorical data. RESULTS: Twenty-seven women who underwent RRSO used HRT after surgery (HRT-users) and 30 did not (HRT-non-users). There were no significant group differences at baseline on the outcome variables. Compared to the HRT-users, the HRT-non-users exhibited a significant increase in overall endocrine symptoms (p = 0.001, effect size (ES) = -0.40 and p < 0.001, ES = -0.59 at T1 and T2, respectively), and in sexual discomfort (p < 0.001, ES = 0.74 and p < 0.001, ES = 1.17). The effect size provides an indication of the magnitude of the observed group differences. An effect size of 0.50 or greater is generally considered to be clinically relevant. No significant differences over time were observed between the HRT-users and the GS-group on any of the outcomes. CONCLUSION: Our results suggest that HRT use in the first year after RRSO has beneficial effects in terms of minimising endocrine symptoms and sexual symptoms in premenopausal women who have undergone RRSO.
