NPM1 (Nucleophosmin 1)

This exploratory study suggests that combining CNAs and gene mutation profiles may potentially improve the existing prognostic evaluation system for NPM1-mutated AML patients. Confirmation of these results requires additional validation in larger prospective cohorts.

As XML continues to unravel the complexities within prostate cancer datasets, the identification of severity-specific biomarkers is poised at the forefront of precision oncology. This integration paves the way for targeted interventions, improving patient outcomes, and heralding a new era of individualized care in the fight against prostate cancer.

Venetoclax-based regimens represent a major advancement in the treatment of NPM1-mutated AML, promoting a shift toward more targeted and less toxic therapeutic approaches. Nonetheless, prospective randomized trials are required to establish standardized clinical algorithms and to refine maintenance and discontinuation strategies, with the ultimate goal of improving patient quality of life and long-term outcomes.

Idarubicin, cytarabine, etoposide (IA ± E) chemotherapy yielded superior survival, while azacitidine+venetoclax (AZA+VEN) regimens underperformed. The study was registered on the Chinese clinical trial registry (ChiCTR) platform (No. ChiCTR2500096484).

In conclusion, FLT3-ITD-based double or triple mutations showed comparable posttransplant outcomes. FLT3-ITD MRD status and early maintenance therapy were key prognostic and therapeutic factors.

The 84 patients (63% KMT2Ar, n=53; 23% NPM1c, n=19) who received MENINi were heavily pre-treated: 86% (n=72) had prior intensive chemotherapy (IC), 77% venetoclax (VEN, n=67), and 38% (n=32) allogeneic stem cell transplantation...Of the 60% (n=50) that were treated, common regimens were hypomethylating agent (HMA)/VEN (26%, n=13), clinical trial (26%, n=13), and gilteritinib-based therapy (18%, n=9)...All CR/CRi occurred with HMA/VEN (n=2, 15%), IC+VEN (n=4, 67%), or MENINi switching (bleximenib to revumenib, n=1, 50%)...Outcomes after MENINi failure are poor, but responses occur with VEN-based regimens or MENINi switching. FLT3-ITD, WT1, and MEN1 mutations are associated with resistance.

Diverse targeted therapeutics may be accessible for the dysregulation of non-KMT2A-dependent HOXA genes, contingent upon the specific genetic alterations. Therefore, a comprehensive understanding of the HOXA signaling network is vital for advancing targeted AML treatments.

P2, N=20, Terminated, Institute of Hematology & Blood Diseases Hospital, China | N=40 --> 20 | Recruiting --> Terminated; The research center has conducted a more comprehensive study.

Key issues ahead include identifying which genetic features truly affect outcomes, using this information to personalize therapy, predicting who will benefit from targeted drugs, and choosing the best markers to track disease response over time. Looking forward, collaborative efforts are urgently needed to validate pediatric-specific biomarkers, test novel drug combinations, and link genetic data to clinical outcomes to design trials and future treatment strategies.

Next-generation agents (ziftomenib, bleximenib, enzomenib, BMF-219) have displayed similar composite complete remission rates (20-35%) and overall response rates (45-65%) in heavily pretreated KMT2Ar and NPM1m acute myeloid leukemia (AML) with measurable residual disease (MRD) negativity and prolonged overall survival (5-7 months)...Acquired mutations in the menin gene described in 39% of post-revumenib relapses have not been identified following other inhibitors (ziftomenib, bleximenib), prompting new questions about resistance mechanisms. These promising results swiftly led to the launch of multiple trials of menin inhibitors combined with intensive (cytarabine and anthracycline) and nonintensive (venetoclax and hypomethylating) chemotherapy backbones...Ongoing/pending phase 3 trials will clarify whether menin blockade should be incorporated into frontline and maintenance regimens for all patients with KMT2A rearranged or NPM1 mutant disease. In the current era, menin inhibition remains a key pillar of the success of precision medicine for AML therapy.

OS was additionally negatively affected when the ten genes were unmutated. Notably, outcomes were excellent for SAR mutations (2-year LFS 76%, OS 84%), indicating allo-HCT in CR1 can overcome their adverse risk at diagnosis.

Among the older cohort, FLT3 and NPM1 mutation status, favorable karyotype, and CCI were not identified as prognostic factors. In the full cohort, using Cox proportional hazard regression and LASSO analyses for age, FLT3 and NPM1 mutation status, cytogenetic risk group, treatment site, race, primary payor, and Charleston Comorbidity Index (CCI), age (HR 65y vs 35y/=2.44, 95% CI 1.61-3.68, p<0.001) was the strongest risk factor in AML.
