[Value of multiparameter flow cytometry in the diagnosis and prognostic evaluation of childhood myelodysplastic syndrome].
OBJECTIVE: To investigate the value of multiparameter flow cytometry (MFC) and flow cytometric scoring system (FCSS) in the diagnosis and prognostic evaluation of childhood myelodysplastic syndrome (MDS).
METHODS: A retrospective analysis was performed for the clinical data of 42 children who were diagnosed with MDS. MFC was performed to investigate the phenotype and proportion of each lineage of bone marrow cells. The correlations of FCSS score with MDS type, International Prognostic Scoring System (IPSS) score, and revised IPSS (IPSS-R) score were analyzed.
RESULTS: Of all the 42 children, 20 (48%) had an increase in abnormal marrow blasts, 19 (45%) had a lymphoid/myeloid ratio of >1, 14 (33%) had abnormal cross-lineage expression of lymphoid antigens in myeloid cells, 8 (19%) had abnormal CD13/CD16 differentiation antigens, 5 (12%) had abnormal expression of CD56, 3 (7%) had reduced or increased side scatter of granulocytes, 3 (7%) had reduced expression of CD36 in nucleated red blood cells, 2 (5%) had reduced expression of CD71 in nucleated red blood cells, 1 (2%) had absent expression of CD33 in myeloid cells, 1 (2%) had reduced or absent expression of CD11b in granulocytes, and 1 (2%) had absent expression of CD56 and CD14 in monocytes. There were significant differences in the median overall survival time and event-free survival time among the low-, medium-, and high-risk FCSS groups (P<0.05). Among the low-, medium-, and high-risk FCSS groups, the low-risk FCSS group had the highest 2-year overall survival rate, while there was no significant difference between the medium- and high-risk FCSS groups (P>0.05). The three groups had a 2-year event-free survival rate of 95%, 60%, and 46% respectively (P<0.05). FCSS score was positively correlated with MDS type, IPSS score, and IPSS-R score (P<0.05).
CONCLUSIONS: MFC and FCSS help with the diagnosis and prognostic evaluation of childhood MDS.
