Significance of Morphological Examination, Cytochemical Staining Combined with Bone Marrow Biopsy in Differential Diagnosis of Myelodysplastic Syndrome with Low Blasts and Hemolytic Anemia / 中国实验血液学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To explore the value of morphological examination, cytochemical staining combined with bone marrow biopsy in the differential diagnosis between myelodysplastic syndrome (MDS) with low blasts and hemolytic anemia (HA).</p><p><b>METHODS</b>The clinical data of 85 cases of myelodysplastic syndrome with low blasts (< 5%) and 61 patients with hemolytic anemia in Chinese PLA's Gerneral hospital from September 2009 to March 2015 were retrospectively analysed. The clinical characteristics, cytogenetic and molecular features, bone marrow cell count and morphology features, cytochemical staining results and bone marrow biopsy features of above-methioned patients were compared.</p><p><b>RESULTS</b>There was no significant difference (P > 0.05) in clinical data between MDS group and HA group. Megakaryocytic dysplasia-positive rate, and ring sideroblasts positive rate, and PAS positive rate were significantly higher in MDS group than those that in HA group (P < 0.05). Abnormal localization of immature precursors (ALIP) and megakaryocytic dysplasia positive rate in bone marrow biopsy were significantly higher in MDS group than those that in HA group (P < 0.05), 90.6% of MDS with low blasts patients were identifiable by combined detections.</p><p><b>CONCLUSION</b>Combining detection of morphology, cytochemistry staining and bone marrow biopsy has been confirmed to be more useful for differential diagnosis between MDS with low blasts and HA.</p>
