Screening of Cancer Patients to Assess Impact of COVID-19

The purpose of this study is to investigate the impact of COVID -19 in the cancer patient population. This will be done by looking at the rate of asymptomatic COVID-19 infection in cancer patients receiving cancer therapy, as well as their immune response. This is a sub-study of the U-DEPLOY study: UHN Umbrella Trial Defining Coordinated Approach to Pandemic Trials of COVID-19 and Data Harmonization to Accelerate Discovery. U-DEPLOY helps to facilitate timely conduct of studies across the University Health Network (UHN) and other centers.
