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

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 (p<0·001). With a follow-up of 2.1 (1·6-2·4) months, 143/425 (33·6%) deaths were reported in the COVID-19+ population: deaths were attributed to COVID-19 (N=73, 51·0%), cancer (N=50, 34·9%) or other causes (N=20, 13·9%). In the COVID-19 negative group, 167 deaths (22·7%) deaths were reported: 138 (82·7%) and 29 (17·3%) were attribued to cancer and other causes respectively. Male gender, age, metastatic disease, immunosuppressive treatments, lymphopenia, COVID-19 diagnosis and diabete were independent risk factors for death. In the COVID-19 positive subgroup with measured CRP at baseline, 65/122 (53·7%) of patients with CRP >100 mg/L vs 35/203 (17·4%) of other patients died before day 28 (p<0·001).Interpretation: 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.

Characteristics and outcome of SARS-CoV-2 infection in cancer patients. (preprint)

Abstract Background: Concerns have emerged about the higher risk of fatal COVID-19 in cancer patients. In this paper, we review the experience of a comprehensive cancer center. Methods: A prospective registry was set up at Institut Curie at the beginning of the COVID-19 pandemic. All cancer patients with suspected or proven COVID-19 were entered and actively followed for 28 days. Results: Among 9,842 patients treated at Institut Curie between mid-March and early May 2020, 141 (1.4%) were diagnosed with COVID-19, based on RT-PCR testing and/or CT-scan. In line with our case-mix, breast cancer (40%) was the most common tumor type, followed by hematological and lung malignancies (both 13%). Patients with active cancer therapy or/and advanced cancer accounted for 88% and 69% of patients, respectively. At diagnosis, 79% of patients had COVID-19 related symptoms, with an extent of lung parenchyma involvement [≤]50% in 90% of patients. Blood count variations and C-reactive protein elevation were the most common laboratory abnormalities. Antibiotics and antiviral agents were administered in 48% and 7% of patients, respectively. At the time of analysis, 26 patients (18%) have died from COVID-19, and 81 (57%) were cured. Independent prognostic factors at the time of COVID-19 diagnosis associated with death or intensive care unit admission were extent of COVID-19 pneumonia and decreased O2 saturation. Conclusions: COVID-19 incidence and presentation in cancer patients appear to be very similar to those in the general population. The outcome of COVID-19 is primarily driven by the initial severity of infection rather than patient or cancer characteristics.
