Introduction: Cancer is one of the main causes of death in Brazil and worldwide. For each year of the triennium 2023-2025, 483,000 new cases are estimated for the country, except non-melanoma skin cancer, breast cancer being the most incident in women with 74,000 new cases. After the declaration of the COVID-19 pandemic by the World Health Organization, several Brazilian states determined restrictive measures to reduce the contamination and cancer diagnosis reference centers were impacted. Objective: To analyze the number of approved breast cancer chemotherapy procedures before and during the COVID-19 pandemic in SUS-affiliated cancer-care facilities in the State of Rio de Janeiro, Brazil. Method: Descriptive design, with time series and ecological analyses using publicly available data of chemotherapy procedures authorized by SUS between March 2018 and February 2021. Results: A total of 394,926 procedures were identified, an increase of 47% with a rising linear trend (R2=0,5203) during the period. Increases in hormonal receptor-positive cancer (46%) and in HER-2 positive carcinoma (900%) were observed. The patients travelled smaller distances for chemotherapy procedures. Conclusion: Results point out a possible effective response by the cancer care network and strengthening of the regionalization during the first pandemic year.
