GEICAM Spanish Breast Cancer Group Steering Committee. GEICAM Guidelines for the Management of Patients with Breast Cancer During the COVID-19 Pandemic in Spain. Oncologist. 2020 Sep;25(9):e1339-e1345.1083-7159http://hdl.handle.net/10668/3269Breast cancer (BC) is the most common cancer in women in Spain. During the COVID-19 pandemic caused by the SARS-CoV-2 virus, patients with BC still require timely treatment and follow-up; however, hospitals are overwhelmed with infected patients and, if exposed, patients with BC are at higher risk for infection and serious complications if infected. Thus, health care providers need to evaluate each BC treatment and in-hospital visit to minimize pandemic-associated risks while maintaining adequate treatment efficacy. Here we present a set of guidelines regarding available options for BC patient management and treatment by BC subtype in the context of the COVID-19 pandemic. Owing to the lack of evidence about COVID-19 infection, these recommendations are mainly based on expert opinion, medical organizations' and societies' recommendations, and some published evidence. We consider this a useful tool to facilitate medical decision making in this health crisis situation we are facing. IMPLICATIONS FOR PRACTICE: This work presents a set of guidelines regarding available options for breast cancer (BC) patient management and treatment by BC subtype in the context of the COVID-19 pandemic. Owing to the suddenness of this health crisis, specialists have to make decisions with little evidence at hand. Thus, these expert guidelines may be a useful tool to facilitate medical decision making in the context of a worldwide pandemic with no resources to spare.7 p.enBreast cancerPandemicCOVID-19SARS-CoV-2Expert recommendationsNeoplasias de la MamaPandemiaCoronavirusSpainEspañaMedical Subject Headings::Diseases::Neoplasms::Neoplasms by Site::Breast NeoplasmsMedical Subject Headings::Health Care::Environment and Public Health::Public Health::Disease Outbreaks::Epidemics::PandemicsMedical Subject Headings::Diseases::Virus Diseases::RNA Virus Infections::Nidovirales Infections::Coronaviridae Infections::Coronavirus InfectionsMedical Subject Headings::Geographical Locations::Geographic Locations::Europe::Spainresearch article32652782open access10.1634/theoncologist.2020-03631549-490XPMC7405405
