Chemoprevention of endometrial cancer in Lynch syndrome: a step forward

Living in the shadow of Lynch Syndrome: British women's accounts

In this paper we explore accounts of eight British women living with Lynch Syndrome: a hereditary syndrome that increases the risk of developing bowel and gynecological cancers. We collected data via semi-structured interviews and analyzed them using Interpretative Phenomenological Analysis. Two themes, 'It's Up to Us': The Lynch Patient Experience; and 'The Biggest Challenge': The Lynch Parent Experience, illustrate the experiential burden and emotional labor of living with Lynch Syndrome. We theorize our analysis through Corbin and Strauss's concept of 'Health Work', and Hochschild's concept of 'Emotion Work'. Recommendations for clinical care and familial support are discussed.

The evolving role of the Women's Health Specialist in cancer prevention and survivorship

IMPORTANCE AND OBJECTIVE

This review provides a framework for primary care physicians, internists, family doctors, NP's, PA's, and oncologists caring for women-henceforth referred to as Women's Health Specialists-to identify and screen patients who may be at high risk for inherited cancer syndromes; an intervention referred to as previvorship care. For women who undergo risk-reducing oophorectomy, survivorship care is critical to optimizing quality of life thereafter. In this paper, we review management of the unique survivorship needs and management options for women at risk for or with a cancer diagnosis, highlighting the importance of interdisciplinary care.

METHODS

To review the available previvorship and survivorship management strategies, a Pub Med search was performed using keywords "survivorship," "genetics," "cancer," "menopause," "hormone therapy," "screening" in addition to review of guidelines, position statements and expert, and committee opinions from the American College of OBGYN, the American Society of Clinical Oncology, The North American Menopause Society, the National Comprehensive Cancer Network , and the American Society for Reproductive Medicine.

DISCUSSION AND CONCLUSION

Women's Health Specialists are in a unique position to identify and screen women who may be at risk for inherited cancer syndromes as well as provide necessary survivorship management following transition from their oncologists' care.

Cost-Effectiveness of Early Detection and Prevention Strategies for Endometrial Cancer-A Systematic Review

Endometrial cancer is the most common female genital tract cancer in developed countries. We systematically reviewed the current health-economic evidence on early detection and prevention strategies for endometrial cancer based on a search in relevant databases (Medline/Embase/Cochrane Library/CRD/EconLit). Study characteristics and results including life-years gained (LYG), quality-adjusted life-years (QALY) gained, and incremental cost-effectiveness ratios (ICERs) were summarized in standardized evidence tables. Economic results were transformed into 2019 euros using standard conversion methods (GDP-PPP, CPI). Seven studies were included, evaluating (1) screening for endometrial cancer in women with different risk profiles, (2) risk-reducing interventions for women at increased or high risk for endometrial cancer, and (3) genetic testing for germline mutations followed by risk-reducing interventions for diagnosed mutation carriers. Compared to no screening, screening with transvaginal sonography (TVS), biomarker CA-125, and endometrial biopsy yielded an ICER of 43,600 EUR/LYG (95,800 EUR/QALY) in women with Lynch syndrome at high endometrial cancer risk. For women considering prophylactic surgery, surgery was more effective and less costly than screening. In obese women, prevention using Levonorgestrel as of age 30 for five years had an ICER of 72,000 EUR/LYG; the ICER for using oral contraceptives for five years as of age 50 was 450,000 EUR/LYG. Genetic testing for mutations in women at increased risk for carrying a mutation followed by risk-reducing surgery yielded ICERs below 40,000 EUR/QALY. Based on study results, preventive surgery in mutation carriers and genetic testing in women at increased risk for mutations are cost-effective. Except for high-risk women, screening using TVS and endometrial biopsy is not cost-effective and may lead to overtreatment. Model-based analyses indicate that future biomarker screening in women at increased risk for cancer may be cost-effective, dependent on high test accuracy and moderate test costs. Future research should reveal risk-adapted early detection and prevention strategies for endometrial cancer.

Screening and diagnosis of endometrial cancer in Lynch syndrome

Lynch syndrome (LS) is an autosomal dominant inherited cancer predisposition syndrome caused by a mismatch of DNA repair (MMR system). Lifetime risk of developing endometrial and ovarian cancer in LS is higher than in the general population and gynecologic screening appears interesting. Screening is based on several tests: pelvic ultrasound, endometrial biopsy and hysteroscopy for endometrial cancer, pelvic ultrasound and CA125 for ovarian cancer. Those tests appear efficient for the diagnosis of gynecologic cancers in LS. Nevertheless, screening tests have not proved clinical benefit until now, and potential problems of compliance, risk of false negative cases, and interval cancer associated with screening do justify offering prophylactic surgery to patients. Women with LS should be informed of the potential benefits and risks of screening and the importance of evaluation in case of gynecologic symptoms or abnormal bleeding. Chemoprevention by progestin-containing oral contraceptives and the treatment of premalignant lesion are available options for reducing the risk of endometrial cancer in LS population.
