COVID-19 Detection Test in Oncology

Patients with cancer are a high-risk group in the COVID-19 pandemic. They are already vulnerable to infection because of their underlying illness and often immunosuppressed status, and are at increased risk of developing severe complications from the virus, including intensive care unit admission or even death. In light of this increased risk, many guidelines have been issued, aiming at minimizing the risk of SARS-CoV-2 infection occurrence and/or gravity. These changes in cancer care could however translate in less efficient or delayed treatments. In this study, we want to detect cancer patients that were exposed to the SARS-CoV-2 virus and acquired an immunity. These patients immune to the SARS-CoV-2 virus are susceptible to receive the standard of care, meaning the most appropriate treatment to manage their cancer. Large-scale serodiagnosis are considered as the solution to progressively relax the current lockdown in France. RDT and ELISA, which were not available until mid-April 2020, will be largely used in the general French population over the coming months, millions of tests have already been ordered by French authorities and companies. The aim of this study is to control that oncology patients qualified immune by local immunoassay are indeed safe (i.e. have extremely low risk of SARS-CoV-2 infection following a positive local immunoassay test). Of note, several immunoassays (RDT or ELISA) will be used in the participating centers throughout the study. A confirmation of positive cases yielded by these different immunoassays will be performed by a centralized ELISA, in order to minimize the risk of false positive results.
