Impact of COVID-19 Disease in Early Breast Cancer Management: A Summary of the Current Evidence.

PURPOSE: An expert panel on breast cancer and COVID-19 disease was convened to address the impact of the COVID-19 pandemic for early breast cancer (eBC) management. METHODS: To ensure that the most clinically relevant information was addressed, essential information was drawn from several of the latest national and international guidelines and another technical document. The expert panel met in five virtual closed sessions from November 2020 to May 2021 to consult on the relevant data from evidence-based results. The data gathered were discussed on an online platform. RESULTS: This article reports the expert panel's highlights of these meetings' discussions. In addition, it provides practical recommendations covering topics regarding diagnosis, treatment, and management of patients with eBC in clinical settings routinely encountered by health care professionals amid the COVID-19 pandemic. CONCLUSION: This article provided guidance on several topics regarding eBC management amid the COVID-19 pandemics to inform safer care practices.

A simplified alternative diagnostic algorithm for SARS-CoV-2 suspected symptomatic patients and confirmed close contacts (asymptomatic): A consensus of Latin American experts.

INTRODUCTION: Latin America accounts for one-quarter of global COVID-19 cases and one-third of deaths. Inequalities in the region lead to barriers to the best use of diagnostic tests during the pandemic. There is a need for simplified guidelines that consider the region's limited health resources, international guidelines, medical literature, and local expertise. METHODS: Using a modified Delphi method, 9 experts from Latin American countries developed a simplified algorithm for COVID-19 diagnosis on the basis of their answers to 24 questions related to diagnostic settings, and discussion of the literature and their experiences. RESULTS: The algorithm considers 3 timeframes (≤7 days, 8-13 days, and ≥14 days) and presents diagnostic options for each. SARS-CoV-2 real- time reverse transcription-polymerase chain reaction is the test of choice from day 1 to 14 after symptom onset or close contact, although antigen testing may be used in specific circumstances, from day 5 to 7. Antibody assays may be used for confirmation, usually after day 14; however, if clinical suspicion is very high, but other tests are negative, these assays may be used as an adjunct to decision-making from day 8 to 13. CONCLUSION: The proposed algorithm aims to support COVID-19 diagnosis decision-making in Latin America.
