Risk factors and clinical characteristics of non-promyelocytic acute myeloid leukemia of intracerebral hemorrhage: A single center study in China.
キーワード
概要
BACKGROUND
Although high mortality in patients with acute leukemia (AL) is associated with intracranial hemorrhage (ICH), the clinical features and pathogenesis of AL patients with cerebral hemorrhage are not well known.
METHODS
We diagnosed 90 patients with ICH from a total of 1467 patients with non-promyelocytic AL who had been hospitalized in the First Affiliated Hospital of Medical School of Zhejiang University from January 2010 to October 2015. Moreover, the risk factors of ICH death were evaluated.
RESULTS
Median age at ICH was 51years old, in which men accounted for 52.2%. They also accounted for 85.6% of acute myeloid leukemia. The relative incidence of ICH was the highest in M2 and M5 (60.1%). ICH presented with higher peripheral blood white blood cell count (WBC) (P<0.001), lower peripheral platelet counts (P<0.001), lower albumin (P<0.001), lower fibrous protein (P<0.001) and prolongation of prothrombin time (P<0.001) compared to those observed in the patients of NICH group; multivariate analysis, independent risk factors for death in patients with ICH include: WBC≥30.00×109/l and prothrombin time≥12.91 s.
CONCLUSIONS
Leukocytosis and coagulation dysfunctions might be the main pathogenesis of acute leukemia complicated with cerebral hemorrhage.
