并分析FLT3-ITD、NPM1突变的关系及其与CD13表达水平的相关性。方法:收集72例AML患者病例资料
采用流式细胞仪检测72例AML患者CD13表达
PCR及Sanger测序法检测FLT3-ITD、NPM1突变。结果:72例AML患者中68例CD13表达阳性(68/72

Objective:To explore the clinical implications of CD13 expression level and the mutation of FLT3-ITD and NPM1 gene in72 acute myeloid leukemia(AML)patients. Methods:Clinical features(blood routine and CR rate)of 72 AML patients were collected.The CD13 expression level was analyzed by flow cytometry and the mutations of FLT3-ITD and NPM1 were detected by polymerase chain reaction(PCR) as well as Sanger sequencing. Results:Totally 68(94.44%) out of 72 AML cases had CD13 expression in leukemia cells;44(64.71%)out of 72 AML cases had complete remission after induction chemotherapy. No statistical difference was found between CD13~+and CD13-patients(P >0.05). Among 68 CD13~+ AML patients
WBC count was higher in patients with FLT3-ITD~+/NPM1~+mutations than in other groups
with statistical differences(P=0.000;P=0.010;P=0.000)and CR rate was lower in patients with FLT3-ITD~+/NPM1~+mutations than in patients with FLT3-ITD~-/NPM1~+and FLT3-ITD~-/NPM1~- (χ2=8.400
P=0.000;χ2=8.88
P=0.000). The median overall survival of FLT3-ITD~+/NPM1~- patients was 24 months
shorter than that of FLT3-ITD~-/NPM1~+and FLT3-ITD~-/NPM1~- patients. FLT3-ITD~-/NPM1~+patients was older than FLT3-ITD~+/NPM1~- patients and had highe WBC and hemoglobin count(P =0.030;P =0.000;P =0.040). FLT3-ITD~-/NPM1 ~+ patients had higher WBC and hemoglobin coun than FLT3-ITD~-/NPM1~- patients(P=0.020;P=0.000). The CR rate was 85.71%
apparently higher than those of FLT3-ITD~+/NPM1 and FLT3-ITD~+/NPM1~- patients(χ2=8.400
P=0.000;χ2=13.450
P=0.000). The median overall survival was 41 months
longer tha those of FLT3-ITD~+/NPM1~+and FLT3-ITD~+/NPM1~- patients. All of these presented a favorable prognosis in FLT3-ITD~-/NPM1~+patients. Conclusion:In 68 CD13~+ patients
FLT3-ITD~+/NPM1~+ patients have higher WBC count and lower CR rate. FLT3-ITD~+/NPM1 patients have shorter survival. FLT3-ITD~-/NPM1~+patients have higher remission rate than FLT3-ITD~+/NPM1~- patients. Combinin detection of CD13 expression and the FLT-ITD/NPM1 mutations can make strong sense for AML cases.
