PURPOSE: Mitigation strategies to balance the risk of coronavirus disease 2019
(COVID-19) infection against oncologic risk in patients with breast cancer
undergoing radiation therapy have been deployed. To this end, shorter
hypofractionated regimens have been recommended where appropriate, with
prioritization of radiation therapy by oncologic risk and omission or deferral of
radiation therapy for lower risk cases. Timely adoption of these measures reduces
COVID-19 risk to both patients and health care workers and preserves resources.
Herein, we present our early response and adaptation of breast radiation therapy
utilization during the COVID-19 pandemic at a large academic cancer center in
Canada. METHODS AND MATERIALS: A state of emergency was announced in Ontario on
March 17, 2020, owing to the COVID-19 pandemic. Emergency guidelines were
instituted. To examine our response, the number of weekly breast radiation
therapy starts, type of breast radiation therapy, and patient age were compared
from March 1 to April 30, 2020 to the same period in 2019. RESULTS: After the
declaration of emergency in Ontario, there was a decrease of 39% in radiation
therapy starts in 2020 compared with 2019 (79 vs 129, P < .001). There was a
relative increase in the proportion of patients receiving regional nodal
irradiation (RNI) in 2020 compared with 2019 (46% vs 29%, respectively), with the
introduction of hypofractionated RNI in 2020 (27 of 54 cases, 50%). A smaller
proportion of patients starting radiation therapy were aged >50 years in 2020,
66% (78 of 118) versus 83% (132 of 160) in 2019, P = .0027. CONCLUSIONS: A
significant reduction in breast radiation therapy starts was noted during the
early response to the COVID-19 pandemic, with prioritization of radiation therapy
to patients associated with higher oncologic risk requiring RNI. A quick response
to a health care crisis is critical and is of particular importance for higher
volume cancer sites where the potential effect on resources is greater.
