ABSTRACT
OBJECTIVE@#To analyze the clinical features and prognosis of 28 children with myelodysplastic syndrome (MDS) and to screen the high risk factors affecting the prognosis so as to provide the new ideas for standard of clinical diagnosis and therapy.@*METHODS@#The clinical data of 28 children with newly diagnosed MDS treated in our hospital from March 1994 to July 2016 were analyzed retrospectively, the features of disease onset and the results of laboratory examination were summarized, all MDS children were followed up, the prognosis and the high risk factors affecting the prognosis were evaluated.@*RESULTS@#In all 28 MDS children, the ratio of male to female was 1.8∶1, the incidence of MDS was observed in boys, while the low incidence of MDS was found in older children. The clinical manifestations were mainly the decrease of three series blood cells in 16 cases (57.14%), other cases presented simple anemia (7.1%), simple thrombocytopenia (7.1%), neutropenia with anemia (14.29%), and anemia with thrombocytopenia (14.28%).The bone marrow image showed mainly hyperplasia (82.14%), and the pathological hematopoiesis, moreover the manifistation of pathological hematopoiesis was different in forma and degree; the bone marrow biopsy showed the typical abnormal localization of immature precursor(ALIP) accepted for 33.33%; the chromosome karyotype detection showed the detected rate of chronosome abnormality was 41.18%. The median follow-up time was 1.75 years. 5 children with MDS received the hematopoietic stem cell transplantation (HSCT), among them 1 dead and 4 maintained CCR; Out of other 23 patients no-received HSCT, 7 cases given up treatment after confirmed diagnosis, 16 cases received the chemotherapy (2 cases given up treatment after CR, 5 cases transformed into AML, 3 cases relapsed, 3 cases maintained CCR), 11 cases dead, 9 cases failed to be followed up. The 5-years OS rate and EFS rate in all patients were predicted as (38.2±11.3)% and (35.3±11.3)%,respectively, among them, the OS and EFS rates of patients received the HSCT allo superior to those of patients did not received HSCT [(80.0±17.9)% vs.(22.8±11.5)%] (P0.05).@*CONCLUSION@#The children MDS is rare and easy to be misdiagnosis, moreover displays more high heterogeneity and poor prognosis, thereby the early diagnosis is crucial, in addition, the system of prognosis evaluation is imperative to be perfected. The HSCT may be the effective method for curative treatment of childhood MDS.
