Mortality of Patients with Cancer Presenting with Symptoms of COVID-19 With vs Without Detectable SARS-CoV-2: A Nationwide Prospective Cohort Study

Abstract

Background: This nationwide prospective cohort reports on the outcome of patients with cancer presenting COVID-19 symptoms with or without detectable SARS-COV2 on RT-PCR and/or specific CT-scan imaging.Methods: This prospective study was conducted in 23 Cancer Centers and hospitals. Inclusion criteria were :1) confirmed diagnosis of solid or hematologic cancer in treatment and 2) clinical symptoms of COVID-19. COVID-19 infection was defined as: 1) detectable SARS-CoV2 on RT-PCR (repeated twice if negative first) and/or specific CT-scan imaging if undocumented SARS-COV-2 on RT-PCR. The primary endpoint was death at day-28 after COVID-19 test, in patients with (COVID-19 positive group) or without (COVID-19 negative group) documented COVID-19.Findings: From March 1st 2020 to May 21st 2020, 1230 cancer patients with suspicion of COVID-19, including 1162 (94·5%) matching inclusion criteria were included. 425 (36·6%) [including 155 [13·3%] with diagnosis on CT-scan only], and 737 (63·4%) were in the COVID-19+ and COVID-19- groups respectively. Deaths within 28 days after COVID-19 diagnosis occurred in 116/425 (27·8%) of COVID-19+ patients, and in 118/737 (16·3%) of COVID-19 negative patients (p100 mg/L vs 35/203 (17·4%) of other patients died before day 28 (pInterpretation: Patients with cancer presenting COVID-19 symptoms with or without detectable SARS-COV-2 by RT-PCR are both at high risk of early mortality. COVID-19 is reported as the cause of death in 50% of the COVID-19 positive patients with cancer.Trial Registration: This trial is registered with ClinicalTrials.gov, number NCT04363632Funding Statement: This work was supported by LYRICAN (INCA-DGOS-INSERM-12563), the French National Research Agency [LabEx DEvweCAN (ANR-10-LABX0061)], RHU4-DEPGYN (ANR-18-RHUS-0009), INCA&DGOS (NetSARC, RREPS, RESOS), INCA (InterSARC), European commission (EURACAN-EC739521), Fondation ARC, PIA Institut Convergence François Rabelais PLAsCAN (17-CONV-0002), La Ligue contre le Cancer, La Ligue de L’Ain contre le Cancer.
