由于缺乏包括该年龄组妇女的研究，对于70岁或以上女性进行乳腺癌筛查仍存在争议。本生态学研究评估了巴西国家卫生服务（SUS）关于巴西全境和地理区域50-69岁和≥70岁女性的乳腺癌筛查和分期数据，时间跨度为2013年至2019年。辅助数据库来自SUS信息部门的门诊数据系统、巴西肿瘤学委员会、巴西地理与统计研究所、补充保健机构和在线死亡率地图。与50-69岁的女性相比，≥70岁的女性筛查明显减少（年百分比变化[APC] -3.5; p < 0.001），而50-69岁的女性筛查减少较小（APC-2.2; p = 0.010）。在≥70岁组中，临床分期呈上升趋势，III期和IV期较多（44.3%），而50-69岁组为40.8%(p < 0.001)。考虑到巴西人口逐渐老龄化和老年妇女之间的异质性，就公共政策的实施而言，SUS应对70岁以上人群的筛查进行更广泛的讨论。Copyright © 2023 Rocha, Freitas-Junior, Soares and Ferreira.

Breast cancer screening in women of 70 years of age or older remains controversial due to a lack of studies that include women of this age.This ecological study evaluated data from the Brazilian National Health Service (SUS) on breast cancer screening and staging in this age group compared to 50-69-year olds, for Brazil as a whole and for its geographical regions, between 2013 and 2019. A secondary database was obtained from the outpatient data system of the SUS's Informatics Department, the Brazil Oncology Panel, the Brazilian Institute of Geography and Statistics, the Supplementary Health Agency and the Online Mortality Atlas.There was a marked reduction in screening in women ≥70 years of age (annual percent change [APC] -3.5; p < 0.001) compared to those of 50-69 years of age (APC-2.2; p = 0.010). There was a trend towards an increase in clinical staging, with a greater occurrence of stages III and IV in the ≥70 group (44.3%) compared to the women of 50-69 years of age (40.8%; p < 0.001).Considering the increasing age of the Brazilian population and the heterogeneity among older adults women, screening for the over-70s within the SUS merits greater debate insofar as the implementation of public policies is concerned.Copyright © 2023 Rocha, Freitas-Junior, Soares and Ferreira.
