Review of current actions in radiotherapy during COVID-19
The current COVID-19 pandemic has, to date, led to nearly 7 million confirmed infections and over 400,000 deaths1. Clearly, all areas of society, including health care systems, have been impacted dramatically.
As a vital component of cancer care, radiotherapy treatments have continued throughout the pandemic, albeit with dramatic changes in order to prioritize care and ensure patient and staff safety. Many institutions have shared their best practices in the literature, and this short article is intended to provide only a brief overview of a few of these resources. One of the earliest publications specific to radiation oncology came from the original epicenter of the crisis, where Wei et al.2 describe changes to infection control procedures and overall workflow at Hubei Cancer Center in Wuhan, China, and demonstrate how these steps could protect patients and staff during the peak of the outbreak.
Within the USA, the Seattle area was one of the first hard-hit areas, and Rengan and Ford3 from the University of Washington provided helpful guidance for clinics that had yet to deal with the coronavirus in their communities. In addition to adjustments to workflow practices for increased infection control, fractionation regimens have also been adjusted to minimize on-site clinical visits, while other treatments could be safely postponed. One example, from a breast cancer population, indicate a dramatic reduction in new patient starts as well as an increase use of hypo-fractionation and higher proportion of advanced disease4.
In order to minimize staff exposure, many radiation oncology staff have transitioned to remote work where possible, including virtual physician visits, treatment planning and plan checking, and procedure coverage5. There are also anecdotal reports of the use of imaging to alerting staff to potential infected patients, either with standard chest CT and image-guided radiotherapy (CBCT), as reported by authors from the US, Italy, and China6-8. Further resources and guidance are available through professional societies9-13. While there are hopeful signs that most areas are past the initial peak of COVID-19 cases, continued vigilance is required as radiation oncology operations slowly and cautiously return to a new normal.
