Abstract
Objective To evaluate the value of immunophenotype in diagnosis of myelodysplastic syndrome (MDS).Methods The immunophenotype of bone marrow cells in 27 patients with MDS were detected by monoclonal antibody by flow cytometry.Results As the progression of the disease,CD34 positive cells gradually increased:refractory anemia/ring sideroblasts refractory anemia (RA/ AS) 7.43 %,refractory anemia with excess of blasts (RAEB) 36.81%,refractory anemia with excess of blasts transformed (RAEB-T)56.45 %,and the differences were statistically significant (P ＜0.05); the expressions of CD33+,CD13 and HLA-DR increased gradually,the expressions of CD14 and CD15 antigens gradually decreased,the difference of three groups was statistically significant (P ＜0.05),the differences between RA/RAS and RAEB-T,RAEB and RAEB-T were statistically significant (P ＜0.05); the expression of CD19 and CD10 decreased and the expression of CD7 increased (RA/RAS 2.63 %,RAEB 10.79 % and RAEB-T 11.00 %) with the progression of the disease,the difference of three groups was statistically significant (F =10.439,P ＜0.05),the differences between RA/RAS and RAEB,RA/RAS and RAEB-T were statistically significant (P ＜0.05).Conclusion The detection of immunophenotype of bone marrow cella in patients with MDS contributes to the diagnosis,classification and prognosis of MDS.
