Novel coronavirus SARS-CoV-2 outbreak and cancer: A literature review

Abstract

Cancer is a significant cause of death worldwide. Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection is spreading rapidly globally. Information on coronavirus disease 2019 (COVID-19) and its complications in cancer patients are still limited. It is relevant to consider that some chemotherapeutic agents have secondary immunosuppressive effects. Approximately 35% of hematologic cancer patients develop pneumonia caused by community respiratory viruses. People older than 65 years-old or with severe neutropenia or lymphopenia are at higher risk. Cancer patients with pneumonia infected by parainfluenza virus showed a higher risk of mortality compared to non-cancer patients (p < 0.05; 12.3% vs. 3.8%) or coronavirus infections (p < 0.01; 24% vs. 30%). Complications associated with SARS-COV2 infection in cancer patients are limited to descriptive studies, with those who received myeloablative, immunosuppressive or monoclonal antibody therapies being more susceptible.
