Health-related quality of life after risk-reducing hysterectomy: a randomised vignette study.

BACKGROUND: Risk-reducing hysterectomy (RRH) is the most effective endometrial cancer preventive strategy. Understanding health-related quality-of-life using health-related utility-scores (HRUS) is essential for counselling, shared decision-making, and informing health-economic evaluations of endometrial cancer prevention. This study aimed to determine HRUS for premenopausal RRH, with and without bilateral salpingo-oophorectomy (BSO). METHODS: Preventing Endometrial-Cancers: Comparing Risk-Reducing Strategies (PRESCORES) (ISRCTN17432105) part-2 is a UK-based randomised vignette study. Following a robust development process, vignettes described four postoperative health-states for a 40-year-old otherwise-healthy woman: "RRH at 1-month", "RRH at 1-year", "RRH-BSO at 1-month", "RRH-BSO at 1-year". These were valued using EQ-5D by participants recruited from the UK general-population and HRUS calculated. Utilities were subsequently adjusted by age-and sex-matched general-population reference values. Association of variables was explored with ordinary-least-squares regression with non-parametric bootstrapping. FINDINGS: Overall, 1001 women were included and randomised to 1-of-4 groups. The mean-age(±SD) was 53.6 (±11.4) years. Mean(±SD) HRUS were 0.942 (±0.072) for "RRH at 1-year", 0.841 (±0.137) for "RRH-BSO at 1-year", 0.670 (±0.149) for "RRH at 1-month", and 0.733 (±0.190) for "RRH-BSO at 1-month", with significant difference between each group (p < 0.001). Adjusting for age-sex-matched population reference utilities, HRUS were 1.000(95% CI:1.00-1.00), 0.994(95% CI:0.97-1.00), 0.866(95% CI:0.84-0.90) and 0.791(95% CI:0.77-0.81), respectively. Participant factors associated with vignette valuations included age, obesity, heavy menstrual-bleeding, higher income and mixed/other ethnicity. CONCLUSION: This randomised study provides HRUS following premenopausal RRH with and without BSO at two postoperative time-points, with adjustment against the age-and sex-matched general reference-population. These values are of relevance for informing counselling of women at increased endometrial cancer-risk regarding RRH and for health-economic evaluations.

Non-invasive screening in hereditary cancer: a randomized controlled trial to test cell-free DNA-based early detection in the CHARM consortium.

Individuals with hereditary cancer syndromes are born with germline genetic variants that significantly increase their lifetime risk of developing multiple cancers. Cancer rates and overall mortality can be reduced with intensive surveillance to facilitate early cancer detection. However, participating in diagnostic imaging and endoscopy surveillance programs is often time-consuming, overwhelming, inconvenient, and anxiety-inducing. To improve this, multi-cancer early detection tests are being developed using cell-free DNA (cfDNA) sequencing analysis to detect cancers with more sensitivity than conventional screening methods. Our community (the CHARM consortium: Cell-free DNA in Hereditary And high-Risk Malignancies) has been exploring the use of cfDNA sequencing in hereditary cancer, and has launched the CHARM2 prospective randomized controlled trial, which is enrolling 1000 participants with Hereditary Breast and Ovarian Cancer, Lynch syndrome, Li-Fraumeni syndrome, Neurofibromatosis type 1 and Hereditary Diffuse Gastric Cancer to improve equitable access, early detection and surveillance for high-risk individuals. All participants will have screening as per conventional syndrome-specific surveillance recommendations. Half the participants (experimental cohort) will also have cfDNA analysis at least three times a year, with abnormal results triggering dedicated clinical imaging and diagnostic evaluation, and heightened surveillance. Vetted by our patient advisors, validated patient-reported outcome and experience measures assessing participant psychosocial outcomes, engagement, and test preferences will be administered to both arms. Our goal is to inform if and how cfDNA analysis could be implemented into routine clinical care and offer a path to equitable and more convenient cancer screening for all high-risk Canadians.
