Introduction: Hematologic malignancies are risk factors for severe COVID-19 infection. Identification of risk factors correlated with mortality in these groups of patients is important in the assessment strategy. We studied the characteristics of patients with hematologic malignancies and COVID-19 and then analyzed the predictors of mortality.
Methods: Eligible for the analysis were hospitalized patients with hematologic malignancies and confirmed COVID-19 infection observed between January 2020 and March 2021. Patients were categorized based on the type of malignancy and phase of the treatment.
Results: A total of 194 COVID-19 infected patients with hematologic malignancies were included. The median age was 44 (15-81) years; 135 of them were males and 59 were females. Acute myeloid leukemia was the most frequent cancer type (43.8%). A total of 119 patients had severe COVID-19 and 61 patients were admitted to the intensive care unit. A total of 92 deaths occurred in all cases for an overall case-fatality rate of 47%. Male gender, preinduction and induction phase of the treatment, intensive care admission, low levels of oxygen saturation, Rhesus (RH) factor positivity, and higher fibrinogen level correlated with mortality.
Conclusion: This study focuses on the epidemiology, risk factors, outcomes, and predictors of mortality of COVID-19 among patients with hematologic malignancies. Patients with hematologic malignancies are at high risk of mortality.
