ABSTRACT
Objective To investigate the clinical and laboratorial characteristics of patients with myelodysplastic syndrome ( MDS) and erythroid hyperplasia.Methods MDS patients whose bone marrow was hypercellular with erythroid lineage more than 50% and blasts account for less than 20% of non-erythroid cells were enrolled in this study.The ratio of mature erythrocytes to nucleated erythrocytes was no more than 20, namely MDS patients with erythroid hyperplasia ( MDS-E ).The retrospective analysis comprised 102 patients with MDS-E from the First Affiliated Hospital of Suzhou University.Clinical characteristics , karyotype , and the prognostic significance of erythroid hyperplasia were evaluated.Results A total of 48 MDS-E patients (47.1%) presented a variety of cytogenetic abnormalities.The most frequently involved chromosomes were chromosome 8 (39.5%of all abnormal karyotypes ), chromosome 7 (22.9%), followed by chromosome 5 ( 18.8%) , chromosome 1 ( 16.7%) and chromosome 20 ( 16.7%) .Hemoglobin ( Hb) level affected the prognosis by survival analysis.The overall survival ( OS) of MDS-E patients with Hb equal or more than 70 g/L was longer than that of patients less than 70 g/L ( P<0.001).Allogeneic hematopoietic stem cell transplantation (HSCT) significantly improved the OS compared with best supportive care (P<0.001) and chemotherapy (P<0.001).The extent of erythroid hyperplasia in bone marrow did not impact on prognosis ( P=0.187 ).Conclusions Compared with previous reports of MDS patients, MDS-E patients have higher level of erythroid hyperplasia , more common erythroid dyshematopoiesis , more frequent 8 and 1 chromosome abnormalities .The degree of erythroid hyperplasia is not correlated with prognosis.Allogeneic hematopoietic stem cell transplantation improves the prognosis.
