#EHA2026 | PRESENTATION
Yue Jin, Peking University People’s Hospital/Peking University Institute of Hematology, presents on the development and validation of a genetic–clinical prognostic algorithm for patients with R/R
#AML undergoing allo-HSCT (derivation, n = 301; external validation, n = 297).
The model integrated OS-associated genetic factors, including FLT3-ITD (HR, 1.70; p = 0.007), mutated TP53 (HR, 2.47; p < 0.001), KMT2A rearrangement (HR, 1.95; p = 0.001), and complex karyotype (HR, 1.80; p = 0.008), with clinical factors including age at allo-HSCT ≥50 years (HR, 1.93; p < 0.001), CR/CRi with MRD before allo-HSCT (HR, 2.22; p < 0.001), active disease before allo-HSCT (HR, 3.26; p < 0.001), and donor age ≥60 years (HR, 2.57; p < 0.001). Based on these factors, patients were stratified into low-, intermediate-low-, intermediate-high-, and high-risk groups. For OS, the 1-, 2-, and 3-year AUCs were 0.826, 0.8156, and 0.819 in the internal validation cohort and 0.725, 0.756, and 0.789 in the external validation cohort, respectively; calibration aligned with observed mortality.
