TP53-mutated AML carries an extremely poor prognosis, significantly worse than other adverse-risk subtypes. When TP53 patients are excluded from analyses, the survival gap between the remaining adverse-risk and intermediate-risk patients narrows considerably, clarifying risk stratification.
The negative ANSA-RAD trial, when contrasted with the positive STAMPEDE trial, demonstrates that patient selection is paramount in adjuvant therapy. The difference in outcomes was driven by risk definition, not the drug. This reinforces that "negative" trials are clinically vital for defining which patient populations do not benefit, preventing widespread overtreatment.
Despite impressive data supporting HMA/Venetoclax, its application in younger, fit patients must be cautious. The pivotal VIALE-A trial excluded key subgroups like FLT3, core binding factor, and certain NPM1 patients, for whom intensive chemotherapy remains the standard.
The FLAG-IDA plus venetoclax regimen achieves very high MRD-negative remission rates. However, its similar efficacy in both frontline and first salvage settings suggests it might be more strategically deployed as a salvage therapy, avoiding its high toxicity in all patients upfront.
The IDH1 inhibitor olutasidenib demonstrates a much longer duration of response than ivosidenib. One hypothesis is that olutasidenib's weaker affinity for wild-type IDH1 makes it a more selective inhibitor of the mutant protein, leading to more durable disease control.
While quizartinib's benefit is less pronounced in AML patients over 60, a specific genomic signature—the co-occurrence of FLT3-ITD, NPM1, and DNMT3A mutations—identifies a subset of older patients who derive a significant survival benefit, challenging age-based treatment decisions.
The NCI-supported MyeloMatch trial is pioneering a new standard for AML diagnostics, providing comprehensive genomic, FISH, and karyotype analysis within 72 hours. This rapid turnaround allows for immediate risk stratification and assignment to appropriate clinical trials.
Traditional age cutoffs for AML therapy are becoming obsolete. A comprehensive fitness assessment, not just chronological age, should guide treatment, as some guidelines now classify patients as young as 55 as "older adults," a surprising shift for many clinicians.
The Spanish KIWI trial showed a surprising survival benefit for quizartinib in FLT3-ITD negative AML. The benefit was greatest in patients with NPM1 and DNMT3A mutations, suggesting the drug's efficacy extends beyond its primary target through other mechanisms.
The Rampart study's use of the Leibovic score for risk stratification is a key strength. Unlike traditional TNM staging, this score more heavily weights tumor grade, which clinicians find to be a more granular and clinically relevant predictor of recurrence risk than just tumor size.
A key advantage of the FLT3 inhibitor quizartinib over midostaurin is its demonstrated survival benefit in FLT3-ITD positive AML patients who do not proceed to an allogeneic transplant in their first remission. This makes it a more robust upfront option for a broader patient group.
