Since December 2019, the world has experienced a pandemic caused by SARS-CoV-2, a virus which spread throughout the world. Anti-COVID19 measures were applied to limit the spread of the infection, affecting normal clinical practice. In 2020, studies on the possible impact of the pandemic considering the screening programs for early diagnosis of cancer were conducted, resulting in a prediction of delayed diagnosis of cancer. We performed a retrospective monocentric study on patients who present with the onset of lymphadenomegalies evaluated at our Hematological Department from February 2019 to October 2021 and undergoing excisional lymph-node biopsy. Three periods were considered: pre-pandemic, first pandemic period and second pandemic period (Group A, B and C). We included 258 patients who underwent a surgical biopsy and received a histological diagnosis. Hematological evaluation of outpatients sent by the general practitioner and surgical biopsies did not decrease among the three groups, despite limitations placed during this pandemic as well as new diagnoses of hematological malignancies. However, the diagnosis of metastatic cancer significantly increased from 2019 (7.8%) to 2021 (22.1%) (p = 0.042). Our data supports the hypothesis that the pandemic affected the national screening programs of early cancer detection.

“…In Brazil, data from DATASUS, an open access database of the Brazilian public healthcare system, show a progressive increase in the number of screening mammograms from 2010 to 2018 20 . However, a retrospective cohort study performed in a private hospital in São Paulo, Brazil, showed a decrease of 78.9% in the number of breast exams in the first 90 days of COVID-19 social isolation measures in comparison to the same period in the previous year 21 . Moreover, almost 70% of responders of an electronic survey with members of the Brazilian Society of Mastology declared they have changed their management approach of BC during the pandemic 22 .…”

Objectives: To describe the sociodemographic characteristics and the findings in the BC screening tests of women who signed up for a Breast Cancer Awareness Month campaign in the Brazilian state of Santa Catarina. Methods: In this descriptive, retrospective, observational study, 638 women volunteered to participate. Sociodemographic and clinical data collection occurred between February 2020 and June 2021. Participants had mammograms and were referred to additional ultrasound exams when necessary. All participants with BI-RADS® of 4 or 5 were referred to core biopsy. Results: In our sample, 31.2% had had a mammography longer than 5 years or had never had it. The most frequent findings in the performed mammograms were: dense breasts (37.1%), microcalcifications (12.0%) and breast lumps (10.4%).
