Short-term effects of the COVID-19 pandemic on cancer screening, diagnosis and treatment procedures in Brazil: a descriptive study, 2019-2020

Abstract

Objective: To analyze the short-term effects of the COVID-19 pandemic on cancer screening, diagnosis and treatment in Brazil. Methods: This was a descriptive study using data from the Outpatient and Hospital Information Systems, and the Cancer Information System. Monthly percentage variation of cancer screening, diagnosis and treatment procedures in 2019 and 2020 was calculated, as well as waiting time for cervical and breast cancer tests. Results: In 2020 cytopathology tests fell by 3,767,686 (-44.6%), screening mammograms fell by 1,624,056 (-42.6%), biopsies fell by 257,697 (-35.3%), cancer surgery fell by 25,172 (-15.7%), and radiotherapy procedures fell by 552 (-0.7%), compared to 2019. Time intervals for performing cervical and breast cancer screening exams were little affected. Conclusion: Cancer control actions were impacted by the pandemic, making it necessary to devise strategies to mitigate the effects of possible delays in diagnosis and treatment
