Since the Coronavirus Disease 2019 (COVID-19) was identified as a global pandemic, health systems have been severely strained, particularly affecting vulnerable populations such as patients with cancer. In response to the COVID-19 pandemic, a variety of oncology specialty societies are making recommendations for standards of care. These diverse standards and gaps in standards can lead to inconsistent and heterogeneous care among governments, cancer centers, and even among oncologists within the same practice. These challenges highlight the need for a common nomenclature and crisis guidelines. For times of increased scarcity of resources, the National Academy of Medicine developed Crisis Standards of Care, defined as fairness, duty to care, duty to steward resources, transparency, consistency, proportionality, and accountability. However, we believe there is an urgent need to develop cancer-specific guidelines by convening a panel of experts from multiple specialties. These would be Crisis Oncology Standards of Care (COSCs) that are sensitive to both the individual cancer patient and to the broader health system in times of scarce resources, such as pandemic, natural disaster, or supply chain disruptions.
