OBJECTIVES: Lifetime cost-effectiveness of returning validated genetic hereditary breast and ovarian cancer (HBOC) risk information to female sample donors was assessed.
METHODS: The FinnGen biobank study analyses genome and health data from 500,000 Finnish biobank participants. The genotyping data produced in the FinnGen study and returned to biobanks was screened for pathogenic variants in BRCA1, BRCA2, and PALB2 genes, and the potential carrier status was verified by sequencing.
To assess the cost-effectiveness of reporting individual HBOC risk results to biobank participants, a cohort simulation model was built with R. Women aged 20-79 years with pathogenic BRCA1/2 or PALB2 variants have a high risk of HBOC; thus, prophylactic interventions, intensified breast cancer (BC) imaging screening, or no change was modelled after the recall. The current care with no recall was the comparator. Modelling followed Finnish guidelines and real-world data. Discounting (3 %/year) was applied to the societal results including health care costs and illness allowances (2022 value). Outcomes included the number of BC/ovarian cancer (OC) cases, deaths due to BC/OC, costs, life-years, quality-adjusted life-years (QALY), and net monetary benefit (NMB) with the estimated prophylaxis willingness-to-pay (28,488€/QALY gained). Sensitivity analyses included mutation type, age groups, and impact of relatives receiving the information.RESULTS: FinnGen data-freeze 7 consisted of 173,746 female donor samples, of which 185 individual’s cohort was modelled to proceed to recall. The recall resulted in an average additional lifetime cost of 2099€/recalled woman.
In the cohort, BC/OCs (26% reduction) and cancer deaths (9% reduction) avoided as well as life-years (136) and QALYs (75) gained were in favor of recall. Recall provided value as the NMB was positive for women with BRCA1/2 mutations aged 20-79 years, and with PALB2 mutations aged 30-59 years.CONCLUSIONS: Returning genomic information to sample donors resulted in noteworthy, modelled health gains and was cost-effective for HBOC.
