| Résumé : | [BDSP. Notice produite par INIST DCR0xKU1. Diffusion soumise à autorisation]. Context Mammography is recommended and is cost-effective for women aged 50 to 69 years, but the value of continuing screening mammography after age 69 years is not known. In particular, older women with low bone mineral density (BMD) have a lower risk of breast cancer and may benefit less from continued screening. Objective To compare life expectancy and cost-effectiveness of screening mammography in elderly women based on 3 screening strategies. Design Decision analysis and cost-effectiveness analysis using a Markov model. Patients General population of women aged 65 years or older. Interventions The analysis compared 3 strategies : (1) Undergoing biennial mammography from age 65 to 69 years ; (2) undergoing biennial mammography from age 65 to 69 years, measurement of distal radial BMD at age 65 years, discontinuing screening at age 69 years in women in the lowest BMD quartile for age, and continuing biennial mammography to age 79 years in those in the top 3 quartiles of distal radius BMD ; and (3) undergoing biennial mammography from age 65 to 79 years. Main Outcome Measures Deaths due to breast cancer averted, life expectancy, and incremental cost-effectiveness ratios. Results Compared with discontinuing mammography screening at age 69 years, measuring BMD at age 65 years in 10 000 women and continuing mammography to age 79 years only in women with BMD in the top 3 quartiles would prevent 9.4 deaths and add, on average, 2.
