摘要
目的:分析研究骨髓增殖性肿瘤(MPN)患者发生血栓事件的危险因素。方法:对391例骨髓增值性肿瘤患者出现血栓事件的情况进行综合分析,其中男195例,年龄15~72岁,平均年龄56岁;女196例,年龄16~60岁,平均年龄48岁。结果:①所有MPN患者中105例发生血栓事件,血栓发生率为26.9%(105/391)。血栓发生率在男女性别之间差异无统计学意义(X~2=0.59,P>0.05);而年龄≥45岁的患者高于年龄<45岁的患者,差异有统计学意义(X~2=16.81,P<0.05);JAK2-V617F阳性的患者高于阴性患者,差异有统计学意义(X~2=23.59,P<0.05);外周血白细胞数量≥10×10~9/L的患者高于白细胞<10×10~9/L的患者,差异有统计学意义(X~2=28.3,P<0.05);外周血血小板数量≥300×10~9/L的患者高于血小板数量<300×10~9/L的患者,差异有统计学意义(X~2=29.14,P<0.05);外周血血红蛋白含量≥160g/L的患者高于血红蛋白含量<160g/L的患者,差异有统计学意义(X~2=30.58,P<0.05)。②采用多因素Logistic回归分析方法,以年龄、性别、白细胞、血小板、血红蛋白、JAK2-V617F阳性为自变量,以血栓为因变量,结果显示:高龄、高白细胞计数、高血小板计数、高血红蛋白含量、JAK2-V617F突变阳性是血栓事件发生的危险因素。结论:MPN患者容易发生血栓事件,对于骨髓增值性肿瘤患者临床出现引发血栓的危险因素时,需要提高注意,应提早采取措施。
Objective:to analyze and study the risk factors of thrombotic events in patients with myeloproliferative neoplasms.Methods:The incidence of thrombotic events in 391 patients with bone marrow proliferative tumors was analyzed. Among them, 195 were males, aged from 14 to 70 years, with a median age of 55 years. There were 196 women, aged 18~61 years, with a median age of 50 years.Results:among 391 patients with MPN, 105 had thromboembolic events, and the incidence of thrombosis was 26.9%(105/391). There was no significant difference in the incidence of thrombosis between men and women(χ~(2 )= 0.59, P> 0.05); however, the incidence of thrombosis was significantly higher in patients older than 45 years than in patients younger than 45 years(X~2 = 16.81, P<0.05); the incidence of thrombosis in JAK2-V617 F positive patients was significantly higher than that in negative patients(X~2 = 23.59, P<0.05); the incidence of thrombosis in patients older than 45 years was significantly higher than that in patients younger There was a significant difference between the patients whose number of cells was more than 10×10~9/L and those whose white blood cells were less than 10×10~9/L(X~2 = 28.3, P<0.05); the patients whose number of peripheral blood platelets was more than 300×10~9/L were higher than those whose number of platelets was less than 300×10~9/L(X~2 = 29.14, P<0.05); and the patients whose hemoglobin content was more than 160 g/L. The difference was statistically significant(X~2 = 30.58, P<0.05) between the patients with higher hemoglobin content<160 g/L. Multivariate logistic regression analysis was performed with thrombotic events as dependent variables and sex, age, JAK2-V617 F positive, leukocyte, hemoglobin and platelet as independent variables. The results showed that the occurrence of thrombotic events was related to the age, JAK2 V617 F positive, high leukocyte count, high hemoglobin content and high platelet count. Risk factors.Conclusions:Patients with MPN are prone to thrombotic events. It is necessary to pay more attention to the risk factors of thrombosis in patients with myeloproliferative tumors and take early measures.
