Clinical significance of GSTM1 and GSTT1 polymorphisms in younger patients with acute myeloid leukemia of intermediate-risk cytogenetics

Abstract We investigated the association between GSTM1 or GSTT1 polymorphisms and clinical outcomes in 133 younger patients with AML of intermediate-risk cytogenetics. Clinical outcomes were not significantly different among the GSTM1 polymorphism genotypes, whereas cumulative incidence of relapse (...

description Abstract We investigated the association between GSTM1 or GSTT1 polymorphisms and clinical outcomes in 133 younger patients with AML of intermediate-risk cytogenetics. Clinical outcomes were not significantly different among the GSTM1 polymorphism genotypes, whereas cumulative incidence of relapse (CIR) was significantly lower and event-free survival (EFS) was significantly higher in patients with the GSTT1 -present genotype compared with those with the GSTT1 -null genotype (CIR at 5 year, 28.9% vs. 44.6%, P = 0.018; EFS at 5 year, 51.4% vs. 34.1%, P = 0.029). Our results suggest that GSTT1 gene polymorphism has significant clinical implications in younger patients with AML of intermediate-risk cytogenetics.
