RESUMO
OBJECTIVE@#To evaluate the diagnostic value of peripheral blood cell parameters for early recognition of myelodysplastic syndrome (MDS) patients.@*METHODS@#The clinical and laboratory data of 86 patients with MDS and 72 patients with non-malignant clonal anemia treated in first diagnosed in the Second Hospital of Hebei Medical University from January 1, 2015 to December 31, 2017 was retrospectively analyzed. The peripheral blood cell parameters of the patients in two groups were analyzed, generated the receiver operator characteristic curve (ROC curve) from the statistically significant parameters, the binary logistic model was build to calculate and compare the area under the ROC curve (AUC) combined with multiple indicators and individual indicators, sensitivity, specificity, positive and negative likelihood ratio, and diagnostic accuracy, the diagnostic efficacy of the patients was analyzed.@*RESULTS@#Compared with patients in the non-malignant clonal anemia group ,white blood cell count (WBC), neutrophil percentage (NE%), eosinophil percentage (E%), eosinophil absolute value (E#), platelet count (PLT), platelet specific volume (PCT%) in the MDS patients were significantly reduced; while percentage of lymphocytes (LY%), basophilic percentage (B%), and the width of platelet distribution (PDW) significantly increased. The several ROC curves with the above indicators were established, which showed that AUC@*CONCLUSION@#PDW, B% and LY% in peripheral blood cell parameters have certain diagnostic value for early recognition of MDS.
