Abstract:
Objective:This study analyzed the clinical characteristics and early mortality risk factors in patients with hyperleukocytic acute leukemia (HAL) to provide a basis for predicting early prognosis.Methods:Data were retrospectively collected from 211 patients with primary HAL who visited the Emergency Center of the Hematology Hospital, Chinese Academy of Medical Sciences, between July 1, 2019 and November 30, 2021. The value of each indicator in early risk stratification and prognosis was analyzed.Results:The early-death group exhibited higher WBC, peripheral blood immature cell proportions, prothrombin times (PT), fibrinogen degradation products (FDP), and D-dimer levels than the non-early death group ( P<0.05). Mortality in hyperleukocytic AML (20.5% ) was significantly higher than that in hyperleukocytic ALL (9.3% ) ( P<0.05). There were significant differences in age, creatinine, PT, fibrinogen (FIB) levels, WBC, lactic dehydrogenase (LDH), uric acid, blood potassium, blood calcium, and blood phosphorus levels between the two groups of patients ( P<0.05). A WBC threshold of 255.96×10?/L predicted early mortality with 65.6% sensitivity and 69.0% specificity, with higher WBC levels associated with a 5.164-fold increased mortality risk ( P<0.05). The age, WBC, LDH, urea, PT, FDP and D-dimer of patients at the time of consultation are risk factors affecting the survival of HAL ( P<0.05) . Conclusion:HAL is a life-threatening condition with a high early mortality. Age, WBC, LDH, urea, PT, FDP and D-dimer are risk factors for early death in HAL.
