Abstract
Abstract Background Acute myeloid leukemia with myelodysplasia‐related changes (AML‐MRC) generally confers poor prognosis, however, patient outcomes are heterogeneous. The impact of TP53 allelic state and variant allele frequency (VAF) in AML‐MRC remains poorly defined. Methods We retrospectively evaluated 266 AML‐MRC patients who had NGS testing at our institution from 2014 to 2020 and analyzed their clinical outcomes based on clinicopathological features. Results TP53 mutations were associated with cytogenetic abnormalities in 5q, 7q, 17p, and complex karyotype. Prognostic evaluation of TP53 MUT AML‐MRC revealed no difference in outcome between TP53 double/multi‐hit state and single‐hit state. Patients with high TP53 MUT variant allele frequency (VAF) had inferior outcomes compared to patients with low TP53 MUT VAF. When compared to TP53 WT patients, TP53 MUT patients had inferior outcomes regardless of MRC‐defining criteria, TP53 allelic state, or VAF. TP53 mutations and elevated serum LDH were independent predictors for inferior OS and EFS, while PHF6 mutations and transplantation were independent predictors for favorable OS and EFS. NRAS mutation was an independent predictor for favorable EFS. Conclusions Our study suggests that TP53 MUT AML‐MRC defines a very‐high‐risk subentity of AML in which novel therapies should be explored.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
