BackgroundElderly patients with acute myeloid leukemia (AML) can be treated with intensive therapy, low-intensity therapy, or best supportive care. Medical decision-making might be affected by physicians’ occupational and non-occupational factors.ObjectiveTo explore the impact of physicians’ personalities and behavioral traits on treatment-related decision-making for elderly AML patients.DesignA nationwide cross-sectional survey.ParticipantsHematologists in mainland China (N = 529; response rate 64.5%).Main MeasuresThe medical decision-making for elderly AML patients was evaluated using 6 clinical vignettes. Hematologists’ attitudes toward risk and uncertainty, Big Five personality traits, and decision-making styles were assessed using binary lottery choices and well-recognized self-report inventories.Key ResultsThe resulting binary regression model in predicting treatment intensity contained professional title group (OR = 0.012, 95% CI 0.001 to 0.136, P < 0.001), conscientiousness (OR = 0.336, 95% CI 0.121 to 0.932, P = 0.036), extraversion (OR = 0.403, 95% CI 0.166 to 0.974, P = 0.044), conscientiousness by title group (OR = 2.009, 95% CI 1.100 to 3.667, P = 0.023), and extraversion by title group (OR = 1.627, 95% CI 0.965 to 2.743, P = 0.068) as predictors of therapy intensity preference. Junior physicians with a higher level of extraversion (mean difference = 0.27; 95% CI 0.07 to 0.45; P = 0.009) or conscientiousness (mean difference = 0.19; 95% CI 0.01 to 0.36; P = 0.028) tended to prescribe more intensive therapy. Meanwhile, no significant correlation was found between physicians’ personalities or behavioral traits and treatment-related decision-making in senior physicians.ConclusionsPhysicians’ personalities contribute to treatment-related decision-making for elderly AML patients, depending on the professional titles. More extravert or conscientious attending physicians tended to prescribe more intensive therapy. Meanwhile, the decisions made by chief and associate chief physicians were not impacted by their personal traits. Junior physicians should be aware of such potential influence when making medical decisions.

Antineoplastic Combined Chemotherapy Protocols - administration & dosage
2026
Hypomethylating agents (HMA) alone or in combination with venetoclax (VEN) are a mainstay for disease control in elderly acute myeloid leukemia (AML). We evaluated the non-inferiority of HMA monotherapy compared to HMA/VEN combination in 227 AML patients aged ≥ 75 years receiving HMA or HMA/VEN combination. No difference in overall survival (OS) was observed between the two groups, with HMA monotherapy demonstrating statistical non-inferiority. HMA-treated patients with favorable performance status had longer OS. The HMA/VEN group experienced higher mortality and worse QoL. HMA monotherapy offers comparable survival outcomes to HMA/VEN with reduced toxicity in elderly AML patients.

Background: Accurate assessment of elderly acute myeloid leukemia (AML) patients is essential before intensive induction chemotherapy and subsequent allogeneic hematopoietic stem cell transplantation. In this context, we investigated the capacity of three scores for frailty prediction. Methods: At diagnosis, 197 patients were clinically evaluated for appropriate treatment intensity. In parallel and independently, the G8-score, the Hematopoietic Stem Cell Index (HCT-CI) and the AML-score for CR were determined for each patient and analyzed with respect to overall survival (OS). Results: The G8-score and the HCT-CI were able to significantly separate “fit” from “unfit” patients, <0.001 and p = 0.008. In univariate Cox models, the predictive role for OS was confirmed: for the G8-score (HR: 2.35, 95% CI 1.53–3.60, p < 0.001), the HCT-CI (HR: 1.91, 95% CI 1.17–3.11, p = 0.009) and the AML-score (HR: 5.59, 95% CI 2.04–15.31, p = 0.001), the latter was subsequently used to verify the cohort. In the multivariate Cox model, the results were confirmed for the G8- (HR: 2.03, p < 0.001) and AML-score (HR: 3.27, p = 0.001). Of interest, when combining the scores, their prediction capacity was significantly enhanced, p < 0.001. Conclusions: The G8-, the HCTCI and the AML-score represent valid tools in the frailty assessment of elderly AML patients at diagnosis.

Prognostic significance of angiogenesis-associated molecules and Immunologic characteristic in elderly patients with acute myeloid leukemia
2025
Background
: Neovascularization mechanisms are hyperactivated in tumors, leading to vascular dysfunction and contributing to tumor metastasis and growth. This study aims to comprehensively analyze angiogenesis-associated genes in relation to the prognosis of elderly patients with acute myeloid leukemia (AML).
Methods
: Leukemia gene expression data were obtained from the GSE37642 (training set) and TCGA_LAML (validation set) datasets. Angiogenesis-associated genes were identified using the GeneCards database. Univariate Cox regression and LASSO analyses were employed to identify angiogenesis-associated genes linked to AML prognosis. A prognostic signature was constructed based on the selected genes, and its biological functions were analyzed. Finally, we predicted AML drug sensitivity and evaluated differences in drug activity based on the prognostic signature.
Results
: Five angiogenesis-related genes associated with AML prognosis were identified: ECM1, EGLN1, FKBP5, FOXP1, and SIRT2. Kaplan-Meier analyses confirmed their prognostic value. A prognostic signature based on these genes demonstrated commendable efficacy in predicting patient outcomes. This signature was found to be an independent risk factor for AML and revealed distinct immune profiles. Furthermore, the signature was implicated in the tumor immune microenvironment, with high-risk patients exhibiting elevated levels of immune cell infiltration. Drug sensitivity analysis revealed negative correlations between FOXP1 and Daporinad, ABT737, and BI.2536, while SIRT2 showed positive correlations with ABT737, BI.2536, and ULK1_4989.
Conclusion
: We have constructed an angiogenesis-related gene prognostic signature that enriches the prognostic assessment system for AML and provides novel therapeutic directions for this disease.

Prognostic and immunological characterization of elderly acute myeloid leukemia evaluated by butyrate metabolism-related genes
2025
Background
The diagnostic and therapeutic value of butyrate metabolism-related genes (BMRGs) in cancer has been widely applied, however, their prognosis and potential therapeutic value in elderly acute myeloid leukemia (EAML) have not been fully elucidated.
Methods
The clinical information and gene expression data of the EAML patients were obtained from the GEO database and TCGA database. Firstly, Least Absolute Shrinkage and Selection Operator (LASSO) and univariate Cox regression were used to screen for BMRGs significantly associated with the prognosis of EAML patients. A prognostic risk stratification model for EAML patients was then constructed based on multivariate COX regression. Prognostic value of the prognostic risk stratification model was confirmed by Kaplan-Meier curves and validated on an independent external queue dataset. Meanwhile, the biological pathways, immune microenvironment and drug sensitivity of EAML patients with different prognostic risk stratification were further analyzed.
Results
4 BMRGs (CCT5, CYP19A1, SECISBP2 and SERINC5) were ultimately identified as genes associated with the prognosis of EAML. A prognostic risk model was constructed based on multivariate COX regression and 4 BMRGs. The Kaplan-Meier curves and independent external queue dataset confirm the prognostic model’s excellent diagnostic value. Immune infiltration analysis’ results confirm 4 BMRGs are correlated with various immune cells significantly.
Conclusion
This was the first comprehensive analysis highlighting the prognostic significance of BMRGs in EAML. The findings not only reveal novel gene biomarkers with potential clinical value but also offer a theoretical foundation for advancing personalized treatment strategies in EAML.

Is there a role for metronomic induction (and maintenance) therapy in elderly patients with acute myeloid leukemia? A literature review
2013
Acute myeloid leukemia (AML) in older adults differs biologically and clinically from that in younger patients and is characterized by adverse chromosomal abnormalities, stronger intrinsic resistance, and lower tolerance to chemotherapy. In patients over age 60 with AML, cure rates are under 10% despite intensive chemotherapy, and most of them die within a year of diagnosis. Over the last decade, metronomic chemotherapy has emerged as a potential strategy to control advanced/refractory cancer. Here, we report a case of a 68-year-old gentleman having AML with high-risk cytogenetic features, who achieved complete remission on our oral metronomic PrET (PrET: Prednisolone, etoposide, thioguanine) protocol on an outpatient basis. He was later treated with standard high-dose (HD) cytosine arabinoside (Ara-C) consolidation followed by maintenance with etoposide, thioguanine, and sodium valproate. Presently, the patient is nearly 35 months since diagnosis and 21 months off treatment. This case report and review highlights that the combination of oral low-intensity metronomic therapy, followed by standard HD consolidation therapy and metronomic maintenance therapy may be well tolerated by elderly patients especially with less proliferative, high (cytogenetic)-risk AML who are otherwise deemed to be unfit for intensive intravenous induction chemotherapy regimens. References for this review were identified through searches of Pubmed for recent publications on the subject as well as searches of the files of the authors themselves. The final list was generated on the basis of originality and relevance to this review.

Acute myeloid leukemia (AML) is the most common acute leukemia in adults. Leukemia stem cells (LSCs) drive the initiation and perpetuation of AML, are quantifiably associated with worse clinical outcomes, and often persist after conventional chemotherapy resulting in relapse

. In this report, we show that treatment of older patients with AML with the B cell lymphoma 2 (BCL-2) inhibitor venetoclax in combination with azacitidine results in deep and durable remissions and is superior to conventional treatments. We hypothesized that these promising clinical results were due to targeting LSCs. Analysis of LSCs from patients undergoing treatment with venetoclax + azacitidine showed disruption of the tricarboxylic acid (TCA) cycle manifested by decreased α-ketoglutarate and increased succinate levels, suggesting inhibition of electron transport chain complex II. In vitro modeling confirmed inhibition of complex II via reduced glutathionylation of succinate dehydrogenase. These metabolic perturbations suppress oxidative phosphorylation (OXPHOS), which efficiently and selectively targets LSCs. Our findings show for the first time that a therapeutic intervention can eradicate LSCs in patients with AML by disrupting the metabolic machinery driving energy metabolism, resulting in promising clinical activity in a patient population with historically poor outcomes.
Targeting of mitochondrial metabolism in combination with BCL-2 inhibition eradicates leukemia stem cells and induces long-lasting responses in patients with acute myeloid leukemia.

Some patients with acute myeloid leukemia (AML) who are in complete remission after induction chemotherapy harbor persisting pre-leukemic clones, carrying a subset of leukemia-associated somatic mutations. There is conflicting evidence on the prognostic relevance of these clones for AML relapse. Here, we characterized paired pre-treatment and remission samples from 126 AML patients for mutations in 68 leukemia-associated genes. Fifty patients (40%) retained ≥1 mutation during remission at a VAF of ≥2%. Mutation persistence was most frequent in DNMT3A (65% of patients with mutations at diagnosis), SRSF2 (64%), TET2 (55%), and ASXL1 (46%), and significantly associated with older age (p < 0.0001) and, in multivariate analyses adjusting for age, genetic risk, and allogeneic transplantation, with inferior relapse-free survival (hazard ratio (HR), 2.34; p = 0.0039) and overall survival (HR, 2.14; p = 0.036). Patients with persisting mutations had a higher cumulative incidence of relapse before, but not after allogeneic stem cell transplantation. Our work underlines the relevance of mutation persistence during first remission as a novel risk factor in AML. Persistence of pre-leukemic clones may contribute to the inferior outcome of elderly AML patients. Allogeneic transplantation abrogated the increased relapse risk associated with persisting pre-leukemic clones, suggesting that mutation persistence may guide post-remission treatment.

Antineoplastic Combined Chemotherapy Protocols - therapeutic use
2025
There is a limited information available on the clinical characteristics, treatment patterns and outcomes on older patients diagnosed with Acute Myeloid Leukemia (AML) in Latin-America. This multicenter retrospective study analyzed 269 patients over 60 years of age diagnosed with AML in Colombia, using data from RENEHOC-PETHEMA registry, from 2009 to 2023. The median age at diagnosis was 70 years (Range:60–98), 55% were men, 61% had an ECOG < 2, and 75.5% had

AML. FLT3-ITD or NPM1 mutations were performed in 23.4% and 15.6% patients, and detected in 14.3% and 16.7% of cases, respectively. Treatment included intensive chemotherapy (IC) (36.8%), Low-Intensity Regimen Based on Low-Dose Cytarabine (LDAC-based) (12.6%), hypomethylating agents (HMAs, with/without venetoclax) (35.3%), and supportive care (15.2%). The overall survival (OS) rate was 35.2% at 1 year and 5.6% at 5 years (13.7% for IC, 9.4% for LDAC-based, and 0% for other treatments); with median OS of 8.2 months (10.6 months after IC, 8.8 months after non-IC, 8.9 months after azacitidine/decitabine, 8.2 months after azacitidine-venetoclax, and 1.9 months with supportive care). Only 1.5% of patients underwent a transplant in the first line. The Leukemia-free survival (LFS) rate was 45.8% at 1-year and 13.7% at 5-years (22.4% for IC, 9.4% and 0% for other treatments); with median LFS of 9.5 months (17.3 months after IC, 7.4 months after LDAC-based, and 10.8 months after HMA). This study provides new insights into the management of patients in Colombia, highlighting the need for a highly individualized approach in treating AML in elderly patients.
