COVID-19 in patients with cancer: Risks and precautions.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a member of the coronavirus family, which causes coronavirus disease 2019 (COVID-19). The phenotype of the disease varies from asymptomatic, to a mild phenotype, through to the severe form of acute respiratory distress syndrome (ARDS), which often leads to death, especially in those with underlying diseases. It has been reported that those who suffer from cancer (especially lung cancer and hematological malignancies) are at higher risk of serious complications and death from COVID-19. Some cancer treatments such as CAR T cell therapy can produce a cytokine storm, which is also a hallmark of severe COVID-19. Therefore, patients receiving CAR T cells are at higher risk if they become infected with COVID-19, and could be treated with anti-cytokine approaches.
