Abstract:
:The International Prognostic Scoring System (IPSS) has been widely used to predict the prognosis of patients with myelodysplastic syndrome (MDS). However, IPSS does not always provide a sufficiently precise evaluation of patients to allow the appropriate choice of clinical interventions. Here, we analyzed the expression of Bmi-1, which is required to regulate the self-renewal in CD34+ cells from 51 patients with cases of MDS and acute myeloid leukemia preceded by MDS (MDS-AML). Higher positivity rate of Bmi-1 was preferentially seen in refractory anemia with excess blasts (RAEB), RAEB in transformation (RAEB-T), and MDS-AML compared with refractory anemia (RA) and RA with ringed sideroblasts (RARS). IPSS score was positively correlated with the percentage of Bmi-1 expression. Patients with RA and RARS with a higher percentage of Bmi-1+ cells showed disease progression to RAEB. Here, we propose Bmi-1 as a novel molecular marker to predict the progression and prognosis of MDS.
