The COVID-19 pandemic has resulted in an unprecedented situation where the standard of care (SOC) management for cancers has been altered significantly. Patients with potentially curable cancers are at risk of not receiving timely SOC multidisciplinary treatments, such as surgery, chemotherapy, radiation therapy, or combination treatments. Hospital resources are in such high demand for COVID-19 patients that procedures, such as surgery, dentistry, interventional radiology, and other ancillary services, are not available for cancer patients. Our tertiary care center is considered the center of the epicenter in the USA. As a result, all non-emergent surgeries have been suspended in order to provide hospital beds and other resources for COVID-19 patients. Additionally, ambulatory efforts to avoid treatment-related morbidity are critical for keeping patients out of emergency departments and hospitals. In this review article, we discuss evidence-based radiation therapy approaches for curable cancer patients during the COVID-19 pandemic. We focus on three scenarios of cancer care: 1) radiation therapy as an alternative to surgery when immediate surgery is not possible, 2) radiation therapy as a 'bridge' to surgery, and 3) radiation options definitively or postoperatively, given the risk of hospitalization with high-dose chemotherapy.
