A substantial investment in resources is required to provide a population-based mammography screening program. At the same time, screening may also reduce the costs of treating breast cancer. Empirical evidence to support such cost savings, however, is limited. This paper presents a simulation of the impact on treatment costs of a population-based mammography screening program in New South Wales. A 1991 cohort of women aged 45 to 69 years is followed for the period 1991 to 2023. With two-yearly screening, the present value of the total health service costs for this cohort would be approximately $112 million. Primary treatment, at $60 million, would cost $5 million more with screening than without. Treatment for advanced stages of the disease would cost $22 million less. Overall, this analysis suggests that savings in treatment costs are relatively small in relation to the overall resource requirements of organised screening.
开展一项基于人群的乳房X光筛查项目需要对资源进行大量投入。与此同时，筛查也可能降低乳腺癌的治疗成本。然而，支持此类成本节约的实证证据有限。本文对新南威尔士州一项基于人群的乳房X光筛查项目对治疗成本的影响进行了模拟。对1991年年龄在45至69岁之间的一组女性进行了1991年至2023年期间的跟踪研究。若每两年进行一次筛查，该组人群医疗服务总成本的现值约为1.12亿澳元。初级治疗成本为6000万澳元，筛查情况下的成本比不进行筛查时高出500万澳元。疾病晚期的治疗成本将减少2200万澳元。总体而言，该分析表明，与有组织筛查的总体资源需求相比，治疗成本的节约相对较小。
