Effect of IL-2Rα expression on cytogenetic-risk classification.

<p>Kaplan—Meier estimates of OS for AML patients ≤60 years old are shown based on the 3 distinct cytogenetic-risk groups. (A) The intermediate-risk group was clearly divided into IL-2Rα⁺ patients and IL-2Rα⁻ patients. (B) Revised survival curves show that the original favorable-risk group, the intermediate-risk group in which IL-2Rα⁺ patients were excluded, and the adverse-risk group in which IL-2Rα⁺ patients in the intermediate-risk group were included.
