[Prognostic significance of EBMT score system for hematological malignancies with allogeneic hematopoietic stem cell transplantation].

OBJECTIVE

To evaluate the impact of EBMT score system in patients with hematological malignancies received allogeneic hematopoietic stem cell transplantation (allo-HSCT).

METHODS

A total of 144 consecutive patients were analyzed retrospectively. According to the EBMT score system, including age, disease status before transplantation, interval between diagnoses to transplantation, donor/recipient sex match and donor type, patients were divided into 3 risk groups: low risk (score 0-1), intermediate risk (score 2-3) and high risk (score 4-7).

RESULTS

The median follow-up duration were 413 (10-1827) days for all patients and 837 (166-1827) days for alive patients. The estimated 4-year overall survival (OS), transplant-related mortality (TRM) and relapse rate (RR) were (57.5±4.6)%, (21.6±3.7)% and (42.7±6.1)%, respectively. The 4-year OS, TRM and RR were (72.2±9.0)%, (8.1±4.5)% and (27.3±8.7)% in the low-risk group, significantly superior to both intermediate-risk group [(57.7±6.0)%, (23.1±5.1)% and (44.9±8.3)%] and high-risk group [(36.9±10.2)%, (33.5±9.2)% and (51.5±11.8)%] (P<0.01, 0.02 and 0.009 for OS, TRM and RR respectively).

CONCLUSION

The EBMT score system provides prognostic significance for OS, TRM and RR in patients with hematological malignancies received allo-HSCT.
