Objectives: This study aimed to evaluate COVID-19 effects on breast cancer screening and clinical stage at diagnosis in patients of 50–69 years of age receiving care within the public healthcare network (SUS) in 2013–2021 in Brazil and its macro-regions.Methods: This ecological study used Poisson regression to analyze trends in screening and staging. A secondary database was formed using SUS sources: outpatient data system of the SUS network and Oncology—Brazil Panel.Results: There was a reduction in screening, with an annual percent change of −5.9 (p < 0.022). The number of notified cases fell by 31.5% in 2020–2021 compared to 2018–2019. There was a 10.7% increase in the proportion of stage III/IV cases (p < 0.001) in 2020–2021 compared to 2013–2019, now surpassing the number of cases of early stage breast cancer.Conclusion: COVID-19 led to a reduction in breast cancer screening and an expressive increase in advanced tumors in users of the public healthcare network. Urgent interventions in public policies are required as the negative effects of the pandemic on the diagnosis/treatment of breast cancer are becoming apparent even earlier than expected.
IntroductionBreast 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.MethodsThis 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.ResultsThere 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).ConclusionConsidering 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.
