Abstract:
OBJECTIVETo analyze the clinical features of clonal evolution of acquired aplastic anemia (AA) into myelodysplastic syndrome/acute myeloid leukemia (AML) and review of literatures.
METHODSAA developing MDS/AML patients between December 1994 and December 2011 enrolled into this study to analyze their clinical characteristics.
RESULTSDuring the median follow-up of 49(15-97) months, 19 patients evolved to MDS/AML, of whom 10, 8 and 1 were from VSAA, SAA and NSAA subgroups, respectively. The median G-CSF therapy was 270(29-510) days. There were monosomy 7 in 11(57.9%) of 19 patients with AA evolved to MDS/AML. The median AA evolved to MDS/AML was 33(11-88) months. The median MDS/AML transformation in responders (54.2 months) was significantly longer than of non-responders (25.7 months, P<0.01).
CONCLUSIONAA patients could evolved into MDS/AML concomitant with abnormal karotype and worse prognosis.
