Ce dossier présente un ensemble d'articles concernant la prise en charge des cancers durant la crise sanitaire liée au COVID-19
Patients with moderate to severe immunosuppression, a condition that is common in many hematologic diseases because of the pathology itself or its treatment, are at high risk for COVID-19 and its complications. While empirical data are sometimes conflicting, this heightened risk has been confirmed in multiple well-done studies for patients with hematologic malignancies, particularly those with B-cell lymphoid malignancies who received lymphocytotoxic therapies, those with a history of recent hematopoietic stem cell transplant and chimeric antigen receptor T-cell therapy, and, to a lesser degree, those with hemoglobinopathies. Patients with immunosuppression need to have a lower threshold for avoiding indoor public spaces where they are unable to effectively keep a safe distance from others, and wear a high-quality well-fitting mask, especially when community levels are not low. They should receive an enhanced initial vaccine regimen and additional boosting. Therapeutic options are available and immunosuppressed patients are prioritized per the NIH.
