Kaplan-Meier plots estimating probability of maintaining CR for adult T-ALL. (A) Twenty-four evaluable patients were assigned to either good-risk or poor-risk T-ALL based on expression of AHNAK, CD2, and TTK as measured by oligonucleotide microarrays. (B) Kaplan-Meier plots based on the WBC count at diagnosis. (C) Kaplan-Meier plots based on the degree of T-lineage differentiation of the leukemic cell (immature = T1-T2; mature = T3-T4 of EGIL classification).
