Impact of the COVID-19 Pandemic on Cervical Cancer Screening in Brazil: A Nationwide Population-Based Study
Year: 2025
Type: article
Study design: Observational Study
Abstract: Cervical cancer is a leading cause of morbidity and mortality among women, particularly in low- and middle-income countries. Early detection through routine Pap smear screening is essential to prevent disease progression. The COVID-19 pandemic severely disrupted healthcare services worldwide, including cancer screening programs. This study aimed to evaluate the impact of the COVID-19 pandemic on cervical cancer screening in Brazil. A nationwide retrospective population-based study was conducted using data from the Cancer Information System (SISCAN) of Brazil’s public health system (SUS). Data from 2018–2019 (pre-pandemic) were compared to 2020–2021 (pandemic period) regarding the number of Pap smear tests performed, regional distribution, and diagnostic outcomes. Furthermore, data from 2022–2023 were incorporated to evaluate the volume of cytopathological exams performed in the post-pandemic context. Statistical analyses included paired t-tests, Wilcoxon signed-rank tests, and repeated measures ANOVA with Bonferroni correction. A significant reduction in Pap smear testing was observed nationwide during the pandemic (p < 0.01), with variations across regions. Despite fewer screenings, there was an increase in unsatisfactory exams and a rise in adenocarcinoma and atypical findings in some regions. In contrast, the post-pandemic period showed a significant recovery in the number of exams, reaching volumes comparable to those observed before the pandemic (p < 0.05). The COVID-19 pandemic substantially reduced cervical cancer screening coverage in Brazil, highlighting structural vulnerabilities in the healthcare system. Strengthening organized screening programs is essential to mitigate the long-term impact of these disruptions.
