Clinical significance of p53 mutations in relapsed T-cell acute lymphoblastic leukemia

Abstract excerpt

In T-cell acute lymphoblastic leukemia (T-ALL), p53 gene mutations were found in 12 of 51 patients in first relapse (24%). In a retrospective study, bone marrow samples at diagnosis were obtained from 9 of the 12 relapsed patients with p53 mutation; only one patient was found to harbor a p53 mutation at diagnosis. No further p53 mutations were identified in 18 unpaired diagnosis T-ALL samples. This is the first...
