Tien FM, Hou HA. CEBPA mutations in acute myeloid leukemia: implications in risk stratification and treatment. Int J Hematol 2024:10.1007/s12185-024-03773-5. [PMID: 38671183 DOI: 10.1007/s12185-024-03773-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2024] [Revised: 04/02/2024] [Accepted: 04/08/2024] [Indexed: 04/28/2024]
Abstract
Mutations in CCAAT enhancer binding protein α (CEBPA) occur in approximately 10% of patients with de novo acute myeloid leukemia (AML). Emerging evidence supports that in-frame mutations in the basic leucine zipper domain of CEBPA (CEBPAbZIP-inf) confer a survival benefit, and CEBPAbZIP-inf replaced CEBPA double mutations (CEBPAdm) as a unique entity in the 2022 World Health Organization (WHO-2022) classification and International Consensus Classification (ICC). However, challenges remain in daily clinical practice since more than 30% patients with CEBPAbZIP-inf die of AML despite intensive treatment. This review aims to provide a comprehensive summary of the heterogeneities observed in AML with CEBPAdm and CEBPAbZIP-inf, and will discuss the prognostic implications of concurrent mutations and novel mechanistic targets that may inform future drug development. The ultimate goal is to optimize clinical management and to provide precision medicine for this category of patients.

Weng W, Chen Y, Wang Y, Ying P, Guo X, Ruan J, Song H, Xu W, Zhang J, Xu X, Tang Y. A scoring system based on fusion genes to predict treatment outcomes of the non-acute promyelocytic leukemia pediatric acute myeloid leukemia. Front Med (Lausanne) 2023; 10:1258038. [PMID: 37942413 PMCID: PMC10628016 DOI: 10.3389/fmed.2023.1258038] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2023] [Accepted: 10/05/2023] [Indexed: 11/10/2023] Open
Abstract
Background Fusion genes are considered to be one of the major drivers behind cancer initiation and progression. Meanwhile, non-acute promyelocytic leukemia (APL) pediatric patients with acute myeloid leukemia (AML) in children had limited treatment efficacy. Hence, we developed and validated a simple clinical scoring system for predicting outcomes in non-APL pediatric patients with AML. Method A total of 184 non-APL pediatric patients with AML who were admitted to our hospital and an independent dataset (318 patients) from the TARGET database were included. Least absolute shrinkage and selection operation (LASSO) and Cox regression analysis were used to identify prognostic factors. Then, a nomogram score was developed to predict the 1, 3, and 5 years overall survival (OS) based on their clinical characteristics and fusion genes. The accuracy of the nomogram score was determined by calibration curves and receiver operating characteristic (ROC) curves. Additionally, an internal verification cohort was used to assess its applicability. Results Based on Cox and LASSO regression analyses, a nomogram score was constructed using clinical characteristics and OS-related fusion genes (CBFβ::MYH11, RUNX1::RUNX1T1, KMT2A::ELL, and KMT2A::MLLT10), yielded good calibration and concordance for predicting OS of non-APL pediatric patients with AML. Furthermore, patients with higher scores exhibited worse outcomes. The nomogram score also demonstrated good discrimination and calibration in the whole cohort and internal validation. Furthermore, artificial neural networks demonstrated that this nomogram score exhibits good predictive performance. Conclusion Our model based on the fusion gene is a prognostic biomarker for non-APL pediatric patients with AML. The nomogram score can provide personalized prognosis prediction, thereby benefiting clinical decision-making.

[Restratifying the prognosis of acute myeloid leukemia patients with CEBPA double mutations based on CSF3R mutations and measurable residual disease]. ZHONGHUA XUE YE XUE ZA ZHI = ZHONGHUA XUEYEXUE ZAZHI 2022; 43:1021-1027. [PMID: 36709108 DOI: 10.3760/cma.j.issn.0253-2727.2022.12.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Figures] [Subscribe] [Scholar Register] [Indexed: 01/30/2023]
Abstract
Objective: This investigation aims to assess the impact of CSF3R mutations and the presence of measurable residual disease (MRD) on the prognosis of patients with CEBPA double mutations who have acute myeloid leukemia (AML) . Methods: The prognostic significance of these two factors was examined in the present study, which included 66 patients with complete genetic mutations and sequential MRD information. Results: Following the second course of chemotherapy, the MRD status and CSF3R mutations of these patients were linked to their long-term prognosis. CSF3R mutated patients showed inferior relapse-free survival (RFS) (5-year RFS: 15.2% vs 38.7% , P=0.006) and overall survival (OS) (5-year OS: 18.2% vs 60.6% , P=0.038) compared with those with wild-type CSF3R. After the second course of chemotherapy, patients with negative MRD had an RFS of 64 months and an OS of not reaching, which was significantly longer than that of patients with positive MRD (15 and 48 months, and the P value were 0.004 and 0.050, respectively) . CSF3R mutations (HR=0.317, 95% CI 0.129-0.779, P=0.012) , WT1 mutations (HR=0.304, 95% CI 0.115-0.804, P=0.016) , and NRAS mutations (HR=0.153, 95% CI 0.061-0.385, P<0.001) were all independently associated with a poor prognosis for RFS, and CSF3R mutations and positive MRD tended to be independently associated with a poor prognosis for OS, according to the results of a Cox proportional-hazards model analysis (P values were 0.071 and 0.088, respectively) . The patients were divided into three groups based on their CSF3R mutation status and MRD status following treatment: wide-type CSF3R and negative MRD, mutated CSF3R or positive MRD, and mutated CSF3R and positive MRD, which showed significantly different RFS (P<0.001) and OS (P=0.006) . Conclusion: Both CSF3R mutations and positive MRD were associated with poor outcome in AML patients with CEBPA double mutations. An integrity model based on these two factors may be beneficial for accurately evaluating the prognosis of these patients.

Abstract
Mutations in CCAAT enhancer binding protein A gene (CEBPA) are one of the common genetic alterations in acute myeloid leukemia (AML). Recently, the emergence of new evidence makes it necessary to reconsider the subsets and treatment of AML patients with CEBPA mutations. This review will summarize the history of research progress of CEBPA mutations in AML, the heterogeneities of AML with CEBPA double mutations (CEBPA dm), and two special subtypes of CEBPA mutated AML. We will discuss the treatment of AML with CEBPA mutations as well, and finally propose a new algorithm for the treatment of these patients, including both familial and sporadic CEBPA mutated AML patients. This review may be beneficial for further investigation and optimizing clinical management of AML patients with CEBPA mutations.
