Association of killer cell immunoglobulin-like receptors and their cognate HLA class I ligands with susceptibility to acute myeloid leukemia in Iranian patients. Sci Rep 2023; 13:11456. [PMID: 37454198 PMCID: PMC10349836 DOI: 10.1038/s41598-023-38479-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2022] [Accepted: 07/09/2023] [Indexed: 07/18/2023] Open
Abstract
Acute myeloid leukemia (AML) is one of the most prevalent leukemia in adults. Among the various NK receptors, killer immunoglobulin-like receptors (KIRs) carry out indispensable roles in NK cell development and function through engaging with class I human leukocyte antigens (HLA-I) as their ligands. Besides divergent KIR and HLA loci, KIR/HLA-I combinations have a significant effect on NK cell response. In this case-control study, we aimed to verify the association of KIR/HLA-I combinations with susceptibility to AML in the Southwestern Iranian population. KIR and HLA genotyping was performed with PCR-SSP by some novel primers for 181 patients with AML and 181 healthy controls. According to our results, the frequencies of KIR3DS1 (p = 0.0001, OR = 2.32, 95% CI 1.51-3.58), KIR2DS4fl (p = 0.02, OR = 1.53, 95% CI 1.05-2.21), CxT4 genotypes (p = 0.03, OR = 2.0, 95% CI 1.05-3.82), and T4 gene cluster (p = 0.01, OR = 1.99, 95% CI 1.17-3.41) were significantly higher in patients than controls, while C1/C2 genotype (p = 0.00002, OR = 0.39, 95% CI 0.25-0.61), HLA-A Bw4 (p = 0.02, OR = 0.6, 95% CI 0.38-0.94), and HLA-A*11 (p = 0.03, OR = 0.57, 95% CI 0.34-0.95) alleles were more frequent in controls. In addition, inhibitory (i)KIR/HLA-I combinations analysis revealed higher frequencies of KIR2DL1( +)/HLA-C2( +), KIR2DL2/3( +)/HLA-C1( +), KIR3DL1( +)/HLA-A Bw4( +), and KIR3DL2( +)/HLA-A*03/11( +) in the control group (p = 0.002, OR = 0.49, 95% CI 0.3-0.78; p = 0.04, OR = 0.62, 95% CI 0.39-0.99; p = 0.04, OR = 0.63, 95% CI 0.4-0.99; and p = 0.03, OR = 0.62, 95% CI 0.4-0.95, respectively). Overall, the number of iKIR/HLA-I combinations was more in the control group. Moreover, KIR3DS1( +)/HLA-B Bw4Ile80( +) and the sum of HLA-B Bw4/A Bw4 combined with KIR3DS1 as activating KIR/HLA-I combinations were more frequent among patients than controls (p = 0.01, OR = 1.99, 95% CI 1.14-3.49 and p = 0.005, OR = 1.97, 95% CI 1.22-3.19, respectively). In conclusion, our results postulate that inhibitory combinations play a protective role against AML by developing potent NK cells during education. It is noteworthy that KIR/HLA-I combination studies can be applicable in donor selection for allogeneic NK cell therapy in hematological malignancies.

Outcomes and survival predictors of Latin American older adults with acute myeloid leukemia: Data from a single center. Hematol Transfus Cell Ther 2023; 45 Suppl 2:S43-S50. [PMID: 35115270 PMCID: PMC10433310 DOI: 10.1016/j.htct.2022.01.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2021] [Revised: 09/04/2021] [Accepted: 01/04/2022] [Indexed: 11/29/2022] Open
Abstract
INTRODUCTION Acute myeloid leukemia (AML) is most commonly presented in older adults; however, it appears 10 years earlier in Latin American countries. Clinical evolution in older adults from this populations has not been characterized. We analyzed outcomes and survival predictors. METHODS Patients ≥ 55 years old diagnosed with AML at a hematology referral center from 2005 to 2020 receiving intensive chemotherapy (IC), low-dose cytarabine (LDAC) and best supportive care (BSC) were included. Survival analysis included the Kaplan-Meier and Cox models and the cumulative incidence of relapse (CIR). RESULTS Seventy-five adults were included and the overall survival (OS) was 4.87, 1.67 and 1.16 months, using IC, LDAC and BSC, respectively. The IC led to a higher OS (p < 0.001) and was a protective factor for early death, at a cost of more days spent hospitalized and more non-fatal treatment complications; non-significant differences were found between the LDAC and BSC. Eight (10.7%) patients underwent hematopoietic cell transplantation, with a higher OS (p = 0.013). Twenty (26.7%) patients achieved complete remission; 12 (60%) relapsed with a 6-month CIR of 57.9% in those < 70 years old vs. 86.5% in those ≥ 70 years old, p = 0.034. Multivariate analysis showed the white blood cell count (WBC) and IC had a significant impact on the patient survival, whereas chronological age and the Charlson comorbidity index (CCI) did not. CONCLUSION AML in low-middle income countries demands a different approach; the IC improves survival, even with a high incidence of relapse, and should be offered as first-line treatment. Eligibility criteria should include WBC and a multidimensional evaluation. The age per se and the CCI should not be exclusion criteria to consider IC.

Abstract
Acute myeloid leukemia (AML) is a hematopoietic malignancy characterized by altered myeloid progenitor cell proliferation and differentiation. As in many other cancers, epigenetic transcriptional repressors such as histone deacetylases (HDACs) are dysregulated in AML. Here, we investigated (1) HDAC gene expression in AML patients and in different AML cell lines and (2) the effect of treating AML cells with the specific class IIA HDAC inhibitor TMP269, by applying proteomic and comparative bioinformatic analyses. We also analyzed cell proliferation, apoptosis, and the cell-killing capacities of TMP269 in combination with venetoclax compared to azacitidine plus venetoclax, by flow cytometry. Our results demonstrate significantly overexpressed class I and class II HDAC genes in AML patients, a phenotype which is conserved in AML cell lines. In AML MOLM-13 cells, TMP269 treatment downregulated a set of ribosomal proteins which are overexpressed in AML patients at the transcriptional level. TMP269 showed anti-proliferative effects and induced additive apoptotic effects in combination with venetoclax. We conclude that TMP269 exerts anti-leukemic activity when combined with venetoclax and has potential as a therapeutic drug in AML.

Abstract
RING-B box-coiled coil (RBCC) domain of promyelocytic leukemia (PML) comprises a zinc finger motif that is targeted by arsenic trioxide (ATO) to treat acute promyelocytic leukemia (APL) pathogenesis. Preliminary evidence suggests that the PML-RBCC has different functional characteristics, but no structural details have been reported despite its importance in differential expression and cell-cycle regulation. Therefore, the recombinant h-PML-RBCC protein was purified to its homogeneity, and characterized for oligomeric behaviour which indicated that RBCC domain exists as a tetramer in solution. Furthermore, nano-DSF and circular-dichroism demonstrated that the tetrameric form preserves its native conformation along with thermal stability (Tm = 83.2 °C). In-silico-based PML-RBCC structure was used to perform the molecular dynamics simulation for 300 ns in the presence of zinc atoms, which demonstrated the differential dynamic of PML-RBCC tetrameric chains. MMPBSA analysis also indicated the role of hydrophobic interactions that favours stable tetrameric structure of PML-RBCC. ATO-induced secondary and tertiary structure changes were observed in PML-RBCC using circular dichroism and fluorescence spectroscopy. Dynamic light scattering and transmission electron microscopy revealed ATO-induced higher-order oligomerization and aggregation of PML-RBCC. The unique oligomeric nature of the h-PML-RBCC protein and its interactions with ATO will help to understand the mechanism of APL pathogenesis and drug resistance.

Abstract
Hematopoietic stem cells (HSCs) are known for their ability to proliferate and self-renew, thus being responsible for sustaining the hematopoietic system and residing in the bone marrow (BM). Leukemic stem cells (LSCs) are recognized by their stemness features such as drug resistance, self-renewal, and undifferentiated state. LSCs are also present in BM, being found in only 0.1%, approximately. This makes their identification and even their differentiation difficult since, despite the mutations, they are cells that still have many similarities with HSCs. Although the common characteristics, LSCs are heterogeneous cells and have different phenotypic characteristics, genetic mutations, and metabolic alterations. This whole set of alterations enables the cell to initiate the process of carcinogenesis, in addition to conferring drug resistance and providing relapses. The study of LSCs has been evolving and its application can help patients, where through its count as a biomarker, it can indicate a prognostic factor and reveal treatment results. The selection of a target to LSC therapy is fundamental. Ideally, the target chosen should be highly expressed by LSCs, highly selective, absence of expression on other cells, in particular HSC, and preferentially expressed by high numbers of patients. In view of the large number of similarities between LSCs and HSCs, it is not surprising that current treatment approaches are limited. In this mini review we seek to describe the immunophenotypic characteristics and mechanisms of resistance presented by LSCs, also approaching possible alternatives for the treatment of patients.

Abstract
Acute myeloid leukemia (AML) is the most common hematological malignancy in adults. In the last decade, internationally approved AML treatment guidelines, including hematopoietic stem cell transplantation are widely used in Kazakhstan. The categorization of acute myeloid leukemia was done according to the French-American British classification. The prognosis of patients at the time of diagnosis was determined by cytogenetic tests following the guidelines of the European LeukemiaNet. The overall survival and event-free survival were analyzed using the Kaplan-Meier method, and hazard ratios were defined with Cox regression. In total, 398 patients with AML were treated in the National Research Oncology Center between 2010 and 2020. The mean age was 38.3 years. We found a correlation between ethnicity, cytogenetic group, white blood cell count, and treatment approaches with overall and event-free survival. There was a significantly longer OS in a cytogenetic group with a good prognosis compared with intermediate and poor prognosis. The median survival time in the group with a good prognosis was 43 months, 23 months in the intermediate group (p = 0.7), and 12 months in the poor prognosis group (p = 0.016). There was a significantly longer OS for the group of patients who received hematopoietic stem cell transplantation (HSCT), 52 months versus 10 months in the group who received chemotherapy only, p-value < 0.0001. Prognostic factors, such as cytogenetic group, initial WBC count, and treatment approaches are significantly associated with patient survival. Our study data were consistent with the most recent studies, available in the literature adjusted for the population in question.

Abstract
Introduction Leukostasis is a medical emergency with high mortality which often occurs in acute myeloid leukemia patients with hyperleukocytosis. One of the therapies that can be used for leukostasis in acute myeloid leukemia is leukapheresis. However, whether leukapheresis can provide better survival benefit when compared with patients not receiving leukapheresis is still unclear. Hence, we aimed to evaluate the effect of chemotherapy plus leukapheresis combination versus chemotherapy only on 28-day survival of acute myeloid leukemia patients with leukostasis. Methods This study was a dual-center retrospective cohort using secondary data from medical records collected from November 2018 to March 2019. Inclusion criteria were adult patients aged 18 years old or above, diagnosed with acute leukemia with hyperleukocytosis status defined by WBC count greater than 100,000/uL, and with symptoms of leukostasis. One-month survival analysis was conducted using Kaplan–Meier curve method. Univariate and multivariate analyses were then conducted using Cox proportional hazards model to obtain value of hazard ratio (HR) with a 95% confidence interval (CI). Results A total of 38 patients were obtained for analysis. The median overall survival was 25 days (95% CI: 17.001–32.999 days) in the chemotherapy only group and 20 days (95% CI: 1.497–38.503) in the chemotherapy with leukapheresis group. The use of leukapheresis did not affect 28-day survival (HR: 1.140; 95% CI: 0.396–3.283; p value: 0.809) and 7-day survival (HR: 1.073; 95% CI: 0.277–4.152; p value: 0.919). In the multivariate analysis, age ≥60 years, blast percentage ≥90%, creatinine ≥1.4 mg/dL, and presence of disseminated intravascular coagulation were associated with worse 28-day survival. Conclusion AML patients with leukostasis who received both chemotherapy and leukapheresis did not have better 28-day survival and 7-day survival when compared with patients receiving chemotherapy only. Old age, high blast percentage, high creatinine, and presence of disseminated intravascular coagulation were prognostic factors for worse 28-day survival.

Abstract
Introduction: Acute myeloid leukemia is a heterogeneous disorder characterized by immature myeloid cell proliferation. Cytogenetic analysis has revealed the presence of chromosomal aberrations important to patient prognosis.
Objective: To determine cytogenetic risk groups of pediatric patients with acute myeloid leukemia according to overall survival.
Materials and methods: In this cross-sectional observational study, the clinical records of pediatric patients diagnosed with de novo acute myeloid leukemia admitted to the Instituto Nacional de Enfermedades Neoplásicas between 2001 and 2011 with cytogenetic analysis of bone marrow were included. Cytogenetic risk groups were established according to the criteria of the Medical Research Council. Overall survival curves were generated with the Kaplan-Meier method and compared using the Mantel-Cox test and Cox regression with the software R, version 3.3.2.
Results: A total of 130 patients were included, 68 males (52.3%) and 62 females (47.7%), most of them with subtype M2 (33%). The average age was 7.7 years (range: 0-15 years). Chromosomal aberrations were observed in 60.8% of the patients, the most frequent of which was the translocation t(8;21). According to the overall survival analysis, two cytogenetic risk groups were established: favorable and unfavorable.
Conclusion: Two groups of cytogenetic risk were determined: high (or unfavorable) and standard (favorable).

Onco Targets Ther 2021; 14:1479-1486. [PMID: 33664580 PMCID: PMC7924121 DOI: 10.2147/ott.s282842] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2020] [Accepted: 12/23/2020] [Indexed: 01/23/2023] Open
Abstract
OBJECTIVE To analyze the association of FLT3-ITD mutation and FLT3 ligand plasma level with one-year survival of Indonesian acute myeloid leukemia (AML) patients. METHODS A prospective cohort study was conducted to determine the association between FLT-3-ITD mutation and FLT3 ligand plasma level with one-year survival of Indonesian AML patients. In the study, a total of 51 AML patients were obtained from two tertiary hospitals in Indonesia from year 2018 to 2020. Inclusion criteria were de novo AML male and female patients aged ≥18 years old. Exclusion criteria were prior myelodysplastic syndrome and patients that refused to participate in the study. FLT3-ITD genotype of patients was then analyzed using PCR method while FLT3 ligand plasma level was measured using ELISA method. Patients were then followed-up for 1 year or until death occurred with survival as the measured outcome. Association between independent and dependent variable were analyzed by cox regression proportional hazard. RESULTS Eleven patients (21.5%) in this study had FLT3-ITD mutation. The median age of AML patients was 45 (18-71) years, and the median blast percentage was 50% (5-87%). After one-year follow-up, 33 (64.7%) patients had died. The median survival of AML patients was 6 months. Univariate analysis showed no association between FLT3-ITD mutation status (HR: 1.051 ; 95% CI: 0.483-2.286; P: 0.901) and FLT3 ligand plasma level (HR: 0.798; 95% CI: 0.347-1.837; p= 0.596), and age (HR: 1.283; 95% CI: 0.575-2.862; p= 0.542) with one-year survival of AML patients, but multivariate analysis showed association between GFR with one-year survival of AML patients in this cohort (HR: 4.053; 95% CI: 1.469-11.183; p= 0.007). CONCLUSION One-year survival of AML patients in Indonesia is not affected by FLT3-ITD mutation and FLT3 ligand plasma level. However, GFR showed association with one-year survival of AML patient in this cohort study.

Abstract
PURPOSE OF REVIEW Acute myeloid leukemia (AML) is a costly disease, and its impact is greater in developing countries (DC). We will review the current concept of what are DC, compare the differences in the epidemiology and economic burden of this disease between developed and DC, and finally, analyze the barriers and possible solutions that DC should implement to achieve better results. RECENT FINDINGS DC is a frequently misunderstood name. The way we use to measure human development is changing, and multidimension metrics better define what are DC. With this in mind, we show the differences in the AML epidemiology and the impact of economic burden in DC. We analyze the barriers to access therapy from a clinician point of view, to show that most DC shared similar challenges but with a diverse healthcare structure. Finally, we provide several possible solutions for a more integrated and timely treatment that allows better results not only in terms of survival but with a better quality of life. The economic burden of AML treatment in DC is high, and the results are poor. It is crucial to face this challenge and propose new treatment approaches to achieve better results.

Abstract
Killer-cell immunoglobulin-like receptors (KIRs) are important because of their key roles in NK cell development and function. Some KIR genes have been associated with the incidence of haematological malignancies. This study was designed to determine whether the inheritance of specific KIR genes is associated with susceptibility to acute myelogenous leukaemia (AML) in Persians living in south-western Iran. KIR genes and KIR2DS4 variants were typed by polymerase chain reaction-sequence-specific primer (PCR-SSP) in 167 patients with AML and 169 healthy controls. Our results showed 10% of patients-mostly females-were classified as M3. Flt3 mutations were detected in 26% of patients, most of whom had internal tandem duplication (ITD). The frequency of activating KIRs (aKIRs)-mainly KIR3DS1-was higher in patients, whereas inhibitory KIRs (iKIRs)-particularly KIR3DL1 and KIR2DL1-were more common among controls. The incidence of the KIR2DS4fl allele was higher among patients with non-M3 AML than controls. We also found a higher frequency of 4 or more iKIR genes in the controls and a higher frequency of 4 or more aKIR genes in the patients. Individuals with more iKIR than aKIR belonged predominantly to the control group. Individuals with the telomeric AA genotype who had inherited the KIR2DS4fl allele were more frequent in the patient group. According to our results, increased frequency of aKIRs in patients with AML may lead to the hyperactivation of NK cells against malignant cells with reduced or lack of HLA class I molecules followed by NK cell exhaustion which allow malignant cells to progress.

Influence of Dose Intensity in Consolidation with HIDAC and Other Clinical and Biological Parameters in the Survival of AML. J Cancer Epidemiol 2020; 2020:8021095. [PMID: 32670373 PMCID: PMC7333041 DOI: 10.1155/2020/8021095] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2020] [Revised: 05/27/2020] [Accepted: 05/28/2020] [Indexed: 11/18/2022] Open
Abstract
Background The impact of the dose intensity administered in consolidation in Latin America is unknown. This study aimed to evaluate the relative dose intensity (RDI) in consolidation and its impact in overall survival. Methods A retrospective study of 86 patients with AML who were diagnosed between 2010 and 2016 with a 2-year follow-up in a fourth-level Colombian hospital was carried out. Clinical characteristics were reported, Kaplan-Meier was used for estimating the overall survival, and Cox regression was used for multivariate analysis. Results The median overall survival (OS) was 20.83 months, and the median event-free survival (EFS) was 16.83 months. 64.3% of the patients achieved remission after the 7 + 3 chemotherapy induction treatment. Patients under 30 years of age, with white blood cell counts less than 100.000 cells/mm3 who responded to induction treatment had a better OS. Additionally, patients receiving an RDI greater than 0.75 of the planned consolidation dose had better survival. The prognostic variables with impact in the OS were the leukocyte count in peripheral blood at diagnosis, the RDI in consolidation treatment with HIDAC and the response obtained after induction. Conclusion This retrospective study allowed us to know the epidemiology of AML in a reference Colombian Hospital. Additionally, in our knowledge, it is the first study that reports the RDI in consolidation with HIDAC in Latin America as a prognostic factor that directly impacts the OS.

Abstract
BACKGROUND We analyzed the cytogenetic characteristics of a representative population of young adults with de novo acute myéloblastic leukemia (AML) treated in a single center institution. METHODS Patients with de novo AML included were aged between 20 and 60 years. Cytogenetic analysis was done at diagnosis. Twenty cells were analyzed, although examination of lower numbers of metaphases was also acceptable if an abnormal clone was detected. FINDINGS From 1/1/04 to 31/12/2014, among 1315 adult patients, 1055 (80%) patients were aged between 20 and 60 years. Karyotype was done in 927 (88%) patients and cytogenetic analysis failed in 32 cases (3·4%). Clonal abnormalities were observed in 520 (58%) patients. 175 (19·5%) were classified in the favorable group, 609 were in the intermediate group and 111 (12·5%) were in the adverse group. The most frequent chromosomal abnormality observed was t(8;21) in 112 (12·5%). Thirty three (3·7%) patients had t(15;17) and 30 (3·3%) had inv16, trisomy 8 was found in 47 (5·2%), 11q23 rearrangements in 32 (3·6%), 67 (7·4%) had a complex karyotype, -5/del(5q) and -7/del(7q) were seen in, respectively, 11(1%) and 27 (3%). Monosomy occurred in 115 (13%) patients, 70 (8%) responded to the definition of monosomal karyotypes. INTERPRETATION This is the largest study done in Morocco, Africa and Middle East. Epidemiological studies involving different ethnic populations and geographic regions of the world should help unfold the true nature of environmental and genetic interplay in the development of AML. Our cytogenetic profile reveals some particularities when compared to other populations; it does not seem to be similar neither to eastern or western countries.

Abstract
Acute leukemia is a heterogeneous set of diseases affecting children and adults. Current prognostic factors are not accurate predictors of the clinical outcome of adult patients and the stratification of risk groups remains insufficient. For that reason, this study proposes a multifactorial analysis which integrates clinical parameters, ex vivo tumor characterization and behavioral in vivo analysis in zebrafish. This model represents a new approach to understand leukemic primary cells behavior and features associated with aggressiveness and metastatic potential. Xenotransplantation of primary samples from patients newly diagnosed with acute leukemia in zebrafish embryos at 48 hpf was used to asses survival rate, dissemination pattern, and metastatic potential. Seven samples from young adults classified in adverse, favorable or intermediate risk group were characterized. Tumor heterogeneity defined by Leukemic stem cell (LSC) proportion, was performed by metabolic and cell membrane biomarkers characterization. Thus, our work combines all these parameters with a robust quantification strategy that provides important information about leukemia biology, their relationship with specific niches and the existent inter and intra-tumor heterogeneity in acute leukemia. In regard to prognostic factors, leukemic stem cell proportion and Patient-derived xenografts (PDX) migration into zebrafish were the variables with highest weights for the prediction analysis. Higher ALDH activity, less differentiated cells and a broader and random migration pattern are related with worse clinical outcome after induction chemotherapy. This model also recapitulates multiple aspects of human acute leukemia and therefore is a promising tool to be employed not only for preclinical studies but also supposes a new tool with a higher resolution compared to traditional methods for an accurate stratification of patients into worse or favorable clinical outcome.

Abstract
Background and aim Acute myeloid leukemia (AML) is one of the most common leukemias in adults. AML is generally regarded as a stem cell disease characterized by an accumulation of undifferentiated and functionally heterogeneous populations of cells, The aim of the present study was to identify leukemia stem cells in patients with AML and their correlations with treatment outcomes namely remission status, disease free survival, and overall survival. Results The mean percentages of CD34+CD38- and CD34+CD38low/−CD123+ LSCs were 2.2± 0.4and 22.3± 2.6, respectively. The percentages of CD34+cells, CD34+CD38- and CD34+CD38low/−CD123+ LSCs were significantly lower in AML patients with complete remission than those without complete response (P<0.001, P<0.004, P<0.001 respectively). The mean OS of all study patients was 20.03±1.2 months while the median OS was 21 months (95% CI=18.32-21.48). The mean DFS was 16.96±1.02 months and the median was 18 months (95% CI=8.9-11.4). DFS and OS were significantly higher among those who achieved CR than those without CR. In addition, there were significant negative effects of WBCs, CD34+cells, CD34+CD38- and CD34+CD38-CD123+LSCs on DFS and OS. Patients and methods We investigated 30 patients with newly diagnosed AML; all patients underwent complete history taking, and thorough physical and clinical examination, complete blood count. Peripheral smears and bone marrow aspirates were also examined. Cytochemistry and immunophenotyping of leukemic cells were performed routinely in bone marrow using monoclonal antibodies. Flow cytometry was used to analyze leukemia stem cells and their expression of CD123. Conclusion Our study elucidated that CD34+CD38-LSCs, with or without CD123+LSCs phenotype was present in a significant proportion of AML patients and it could be responsible for resistance to traditional treatments, and high percentage of MRD that was translated into significantly high number of non CR, poor DFS, and OS.

Abstract
The purpose of this study was to investigate the expression status of Dual-Specificity Phosphatase 5 Pseudogene 1 (DUSP5P1) and its clinical relevance in patients with acute myeloid leukemia (AML). Real-time quantitative PCR (RQ-PCR) was performed to detect the status of DUSP5P1 expression in 89 patients with de novo AML and 24 normal controls. The level of DUSP5P1 expression was significantly up-regulated in AML compared to controls (P=0.031). The patients with high expression of DUSP5P1 had higher percentage of blasts in bone marrow (BM) than those without high expression (P=0.027). The occurrence rate of DUSP5P1 high expression was significantly higher in M1 (2/8, 25%) and M2 subtypes (9/33, 27%) than in M3 subtype (0/17, 0%) (P=0.034). At the same time, the frequency of DUSP5P1 high expression in patients with intermediate (13/53, 24%) and poor karyotypes (5/11, 45%) was significantly higher than that in patients with favorable karyotype (0/21, 0%) (P=0.003). Meanwhile, DUSP5P1 high-expressed patients had significantly shorter overall survival (OS) than those with low expression (median 4.5 vs. 10.5 months, respectively, P=0.038). Our findings indicated that high expression of DUSP5P1 may identify high-risk AML patients and is associated with poor prognosis in AML.
