In the time of COVID-19: challenges, successes and lessons learned from studies in cancer patients
Cet article souligne les enjeux et les enseignements tirés des études incluant des patients atteints d'un cancer pendant la pandémie de la COVID-19
The COVID-19 pandemic created the urgent need to monitor risk of SARS-CoV-2 infection and mortality, and to evaluate immune responses to novel vaccines. A foremost concern was the unknown risks to patients with cancer, considering their overall health, immune status and interactions with cancer therapies. The U.S. National Cancer Institute, in partnership with the National Institute of Allergy and Infectious Diseases, established the SARS-CoV-2 Serological Sciences Network (SeroNet) as the nation’s largest coordinated effort to identify and establish standardized serology tests to study immune responses against SARS-CoV-2. SeroNet-sponsored institutions established cohort studies in 2020 and 2021 across the nation to prospectively follow over 3,000 patients with solid and hematologic malignancies. Concerted efforts were launched to define common data elements for self-reported and clinicopathological data as well as standardized approaches for serological, cellular and molecular assays. However, the urgency of the situation, the pace of scientific evolution and the changing public health landscape presented unique challenges to this effort. Here, we discuss these challenges, including regulatory and institution-specific requirements, enrollment of participants, data and biospecimen collection and harmonization, and the need to adapt study designs to align with the ever-changing landscape. This information is critical to the continuance of research on SARS-CoV-2 and provides a roadmap for combatting the emergence of future pathogens with pandemic potential.
