Number of SARS-COV-2 infections (symptomatic or asymptomatic): detected by routine SARS-COV-2 tests in all patients treated at the Division of Oncology, Medical University of Vienna. During the SARSCOV-2 pandemic, the routine approach to patients undergoing chemotherapy at our institution is PCR from nasal swabs taken every 28 days. The cumulative number of infections detected (symptomatic or asymptomatic) at week 8 after initiation of therapy in both treatment arms serves as the primary endpoint.
