Disparities in mortality risk after diagnosis of hematological malignancies in 185 countries: A global data analysis. Cancer Lett 2024; 595:216793. [PMID: 38513800 DOI: 10.1016/j.canlet.2024.216793] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2023] [Revised: 02/23/2024] [Accepted: 03/04/2024] [Indexed: 03/23/2024]
Abstract
This study was to report proxy measures for mortality risk in patients with hematological malignancies across 185 countries globally and explore its association with their socioeconomic status and treatment. The incidence, mortality, and 5-year prevalence data were extracted from the GLOBOCAN database. The data regarding the human development index (HDI), gross national income (GNI), vulnerability index, and concordance with cancer Essential Medicines List (EML) were obtained from open-source reports. The ratio of mortality to 5-year-prevalence (MPR) and that of mortality to incidence (MIR) were calculated and age-standardized using Segi's world standard population. Finally, the possible associations were assessed using Pearson correlation analyses. In 2020, the global incidence, mortality, and 5-year prevalence of HMs were 1,278,362, 711,840, and 3,616,685, respectively. Global age-standardized MPR and MIR were 0.15 and 0.44, respectively; they varied significantly among 6 regions, 185 countries, 4 HM types, and 4 HDI groups worldwide. Older populations always had higher ratios. The correlation of MPRs and MIRs with HDI, GNI, and concordance with cancer EML was negative, whereas it was positive with the vulnerability index (lower was better). Increasing access to cancer drugs in resource-limited regions with a focus on vulnerable children may aid in reducing HM-related mortality risk.

Investigating the multifaceted cooperation of autophagy, PI3K/AKT signaling pathways, and INPP4B gene in de novo acute myeloid leukemia patients. Curr Res Transl Med 2024; 72:103429. [PMID: 38246071 DOI: 10.1016/j.retram.2023.103429] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2023] [Revised: 10/20/2023] [Accepted: 10/30/2023] [Indexed: 01/23/2024]
Abstract
BACKGROUND Acute myeloid leukemia (AML) has been the most prevalent form of acute leukemia among adults, and it has been associated with poor survival rates over the last four decades. Understanding the processes involved in leukemogenesis, particularly autophagy and signaling pathways, can provide critical insights into their roles in disease development, risk assessment, and potential therapeutic interventions. This study investigated gene expression changes, focusing on MAP1LC3B and BECN1, related to autophagy, as well as PI3KCA and AKT1 in the PI3K-AKT pathway, and INPP4B, which regulates this signaling cascade. METHODS We collected blood samples from 21 AML patients and 9 healthy volunteers. Gene expression was analyzed through qPCR following RNA extraction and cDNA synthesis. Statistical analysis encompassed t-tests, ANOVA, and correlation coefficients. RESULTS AML patients exhibited significantly increased MAP1LC3B gene expression (****P < 0.0001; fold change = 11.9) and significantly reduced levels of INPP4B (****P < 0.0001; fold change = 0.026), AKT1 (*P < 0.05; fold change = 0.59), and PI3KCA (****P < 0.0001; fold change = 0.16) compared to healthy controls. However, BECN1 gene expression did not significantly differ between the two groups. Additionally, noteworthy correlations were observed between INPP4B and BECN1 (r = 0.57; P = 0.006) and BECN1 and PI3KCA (r = 0.61; P = 0.003) in AML patients. CONCLUSIONS This study highlights variations in leukemogenesis pathways, exemplified by increased MAP1LC3B expression and diminished expression of regulatory genes in specific AML cases. These findings contribute to our comprehension of the molecular mechanisms underlying AML and may inform future diagnostic and therapeutic approaches.

Abstract
A retrospective case series design was conducted to elucidate the demographic features of acute myeloid leukaemia in Afghanistan. This study was conducted at Jamhuriat Hospital and French Medical Institute for Mothers and Children, Kabul, Afghanistan. A total of 203 patients with AML diagnosed and managed at Jamhuriat Hospital from 1 March 2018 to 31 March 2020, were included in the current study. The median age at diagnosis was 27 years. Housewives represented the largest subset of patients from an occupational point of view constituting 37.44% of the total sample population and 81.72% of the female population, followed by 20.69% patients who were students of which 14.77% were male and 5.91% were female, and 17.24% were farmers, which constituted 31.81% of the male population. Similarly, 69.95% of individuals presented with infection, 57.14% presented with bone tenderness, 46.3% presented with bleeding tendencies, 55.66% had hepatomegaly and/or splenomegaly, and 27.58% of patients had lymphadenopathy. Considering the chemotherapeutic regime, 64.53% of the individuals received standard 7 + 3 (cytarabine + daunorubicin) induction regimen, 10.68% of those received 5 + 2 re-induction chemotherapy (cytarabine + daunorubicin). 10.84% who were diagnosed with acute promyelocytic leukaemia received all-trans-retinoic acid + arsenic trioxide, while 5.42% of patients defaulted chemotherapy. High prevalence was noted in young individuals. Similarly, a high proportion of patients were constituted by housewives.

Abstract
BACKGROUND Long non-coding RNAs (lncRNAs) have been reported to have a crucial impact on the pathogenesis of acute myeloid leukemia (AML). Cuproptosis, a copper-triggered modality of mitochondrial cell death, might serve as a promising therapeutic target for cancer treatment and clinical outcome prediction. Nevertheless, the role of cuproptosis-related lncRNAs in AML is not fully understood. METHODS The RNA sequencing data and demographic characteristics of AML patients were downloaded from The Cancer Genome Atlas database. Pearson correlation analysis, the least absolute shrinkage and selection operator algorithm, and univariable and multivariable Cox regression analyses were applied to identify the cuproptosis-related lncRNA signature and determine its feasibility for AML prognosis prediction. The performance of the proposed signature was evaluated via Kaplan-Meier survival analysis, receiver operating characteristic curves, and principal component analysis. Functional analysis was implemented to uncover the potential prognostic mechanisms. Additionally, quantitative real-time PCR (qRT-PCR) was employed to validate the expression of the prognostic lncRNAs in AML samples. RESULTS A signature consisting of seven cuproptosis-related lncRNAs (namely NFE4, LINC00989, LINC02062, AC006460.2, AL353796.1, PSMB8-AS1, and AC000120.1) was proposed. Multivariable cox regression analysis revealed that the proposed signature was an independent prognostic factor for AML. Notably, the nomogram based on this signature showed excellent accuracy in predicting the 1-, 3-, and 5-year survival (area under curve = 0.846, 0.801, and 0.895, respectively). Functional analysis results suggested the existence of a significant association between the prognostic signature and immune-related pathways. The expression pattern of the lncRNAs was validated in AML samples. CONCLUSION Collectively, we constructed a prediction model based on seven cuproptosis-related lncRNAs for AML prognosis. The obtained risk score may reveal the immunotherapy response in patients with this disease.

Abstract
Over 30-35% of patients down with AML are caused by mutations of FLT3-ITD and FLT3-TKD which keeps the protein activated while it activates other signaling proteins downstream that are involved in cell proliferation, differentiation, and survival. As drug targets, many inhibitors are already in clinical practice. Unfortunately, the average overall survival rate for patients on medication suffering from AML is 5 years despite the huge efforts in this field. To perform docking simulation and ADMET studies on selected phytochemicals against FLT3 protein receptor for drug discovery against FLT3 induced AML, molecular docking simulation was performed using human FLT3 protein target (PDB ID: 6JQR) and 313 phytochemicals with standard anticancer drugs (Sorafenib and Gilteritinib in addition to other anticancer drugs). The crystal structure of the protein was downloaded from the protein data bank and prepared using Biovia Discovery Studio. The chemical structures of the phytochemicals were downloaded from the NCBI PubChem database and prepared using Open Babel and VConf softwares. Molecular docking was performed using PyRx on Autodock Vina. The ADMET properties of the best performing compounds were calculated using SwissADME and pkCMS web servers. The results obtained showed that glabridin, ellipticine and derivatives (elliptinium and 9-methoxyellipticine), mezerein, ursolic acid, formononetin, cycloartocarpesin, hypericin, silymarin, and indirubin are the best performing compounds better than sorafenib and gilteritinib based on their binding affinities. The top-performing compounds which had better binding and ADMET properties than sorafenib and gilteritinib could serve as scaffolds or leads for new drug discovery against FLT3 induced AML.Communicated by Ramaswamy H.

Abstract
Background Acute myeloid leukemia (AML) is a diverse disease characterized by the expansion of blasts of myeloid lineage. Cytogenetic testing is the cornerstone for risk stratification of AML patients. Geographical and environmental factors may play a very important role in the development of leukemia and several differences in genetic profile may be seen among different ethnicities. In our study, we evaluated cytogenetic findings of adult AML patients in South Egypt. Methods Cytogenetic testing (karyotyping and M-FISH) was performed for 120 adult patients with AML. Twenty metaphases were analyzed for each patient. Results In our study, the median age of AML patients was 36.5 years, with an age range between 18 and 86 years. 56.7% of patients had normal karyotypes and 43.3% of patients had clonal cytogenetic abnormalities. t (15;17) was the most detected structural abnormality, and + 8 was the most detected numerical abnormality. Regarding cytogenetic risk stratification, 65% of patients were in the intermediate-risk category. Conclusion The cytogenetic profile of AML patients in our locality showed some differences and some similarities with cytogenetic profiles in different Arab, Asian and Western countries. Further studies are needed using advanced techniques such as next-generation sequencing and optical genome mapping to elucidate more ethnic and geographic genetic heterogeneity among different countries.

Abstract
INTRODUCTION Acute myeloid leukemia (AML) is a rare blood cancer with a poor prognosis. Recently, targeted drugs have improved survival both in the elderly and in fit patients. However, as monthly costs of targeted agents are high, regulatory bodies often impose restrictions on their use. AREAS COVERED The authors review the value-for-cost of targeted drugs such as gemtuzumab ozogamycin, CPX-351, midostaurin, gilteritinib, glasdegib, venetoclax, oral azacytidine and enasidenib used to treat adult AML. EMBASE and TRIP databases, together with authority websites were searched for technology assessments. Add-on drugs, namely midostaurin and gemtuzumab ozogamycin, have been reported to have the best pharmacoeconomic profile for newly diagnosed fit patients with FLT3 mutation or favorable/intermediate cytogenetics, since allogeneic transplant rates were stable or reduced. Most of the other drugs, on the other hand, did not achieve highly favorable cost-for-benefit, due to a poor absolute survival gain and/or increased transplant rates. EXPERT OPINION The cost of most targeted therapies for AML in unfit patients seems unfair in comparison to the absolute survival advantage provided in fit patients. Point of cure and transplant outcomes should be standardized to allow comparability among the models.

Abstract
Despite the continuous improvement of leukemia treatment in the clinic, the overall 5-year disease-free survival of acute myeloid leukemia (AML) is only approximately 30%-60% due to relapse and the refractoriness of AML after traditional chemotherapy. Inhibition of poly(ADP-ribose) polymerase (PARP), a member of the DNA damage repair complex, has a strong antitumor effect in solid tumors. However, the role of PARP in AML remains unclear. We found that high levels of PARP1 and PARP2 were positively related to chemotherapy resistance and poor prognosis in patients with AML. Doxorubicin (DOX)-resistant AML cells highly expressed PAPR1 and PARP2. Knockdown of PARP1 and PARP2, or pharmaceutical inhibition of PARP by the PARP inhibitor (PARPi) BGB-290, significantly enhanced the cytotoxicity of DOX in AML cells due to increased DNA damage. PLGA-loading BGB-290 was properly self-assembled into stable BGB-290@PLGA nanoparticles (NPs), which is uniform particle size and good stability. BGB-290@PLGA is easily uptake by AML cell lines and stays for a long time. Combined with DOX, BGB-290@PLGA can significantly improve the chemosensitivity of AML cell lines. Furthermore, BGB-290 and DOX combination treatment dramatically repressed the onset of leukemia and prolonged the survival of THP-1 xenografted mice. Overall, this study demonstrated that PARPi with traditional chemotherapy could be an efficient therapeutic strategy for AML.

Introduction: Acute myeloid leukemia (AML) is the commonest leukemia in adults. Mortality in thew first 30-days ranges from 6% to 43%, while infections account for 30–66% of early deaths. We aim to present our experience of infections in newly-diagnosed AML. Method: This prospective, observational study, was undertaken at a tertiary care hospital in Northern India. Patients with confirmed AML (bone marrow morphology and flow cytometry) and who had developed febrile neutropenia (FN), were included. Result: A total of fifty-five patients were included in the study. The median age of the patients was 47.1 years (12–71) and 28 (50.9%) were males. Fever (33, 60%) was the commonest presentation at the time of diagnosis. One or more comorbid conditions were present in 20 patients (36.36%). Infection at presentation was detected in 17 patients (30.9%). The mean duration to develop febrile neutropenia since the start of therapy was 11.24 days. With each ten-thousand increase in white blood cell (WBC) count, the mean number of days of FN development decreased by 0.35 days (p = 0.029). Clinical and/or radiological localization was possible in 23 patients (41.81%). Thirty-four blood samples (34/242, 14.04%) from 26 patients (26/55, 47.3%) isolated one or more organisms. Gram negative bacilli (GNB) were isolated in 24 (70.58%) samples. Burkholderia cepacia (8/34, 23.52%) was the commonest organism. The number of days required to develop febrile neutropenia was inversely associated with overall survival (OS). However, when compared, there was no statistically significant difference in OS between patients developing fever on day-10 and day-25 (p = 0.063). Thirteen patients (23.63%) died during the study period. Discussion: Low percentage of blood culture positivity and high incidence of MDR organisms are a matter of concern. Days to develop febrile neutropenia were inversely associated with overall survival (OS), emphasizing the importance of preventive measures against infections. Conclusion: Infections continues to be a major cause of morbidity and mortality among AML patients.

Abstract
There are no published data on long‐term survival and applicability of treatment protocols from developed countries in acute myeloid leukaemia (AML) in Sri Lanka. Eighty‐seven AML patients were reviewed; there were 56 newly diagnosed patients between 18 and 65 years. Thirty‐one out of 33 who started treatment achieved complete remission after first cycle of treatment. The induction mortality was one of 33. Twelve out of 20 patients who completed treatment are alive at the time of analysis. The estimated 5‐year overall survival rate is 0.629. Strict infection control and treatment and superior clinical experience may have contributed towards better outcome.

Inhibitors of Chemoresistance Pathways in Combination with Ara-C to Overcome Multidrug Resistance in AML. A Mini Review. Int J Mol Sci 2021; 22:ijms22094955. [PMID: 34066940 PMCID: PMC8124548 DOI: 10.3390/ijms22094955] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2021] [Revised: 04/30/2021] [Accepted: 05/03/2021] [Indexed: 12/12/2022] Open
Abstract
Acute myeloid leukemia (AML), the most common type of leukemia in older adults, is a heterogeneous disease that originates from the clonal expansion of undifferentiated hematopoietic progenitor cells. These cells present a remarkable variety of genes and proteins with altered expression and function. Despite significant advances in understanding the molecular panorama of AML and the development of therapies that target mutations, survival has not improved significantly, and the therapy standard is still based on highly toxic chemotherapy, which includes cytarabine (Ara-C) and allogeneic hematopoietic cell transplantation. Approximately 60% of AML patients respond favorably to these treatments and go into complete remission; however, most eventually relapse, develop refractory disease or chemoresistance, and do not survive for more than five years. Therefore, drug resistance that initially occurs in leukemic cells (primary resistance) or that develops during or after treatment (acquired resistance) has become the main obstacle to AML treatment. In this work, the main molecules responsible for generating chemoresistance to Ara-C in AML are discussed, as well as some of the newer strategies to overcome it, such as the inclusion of molecules that can induce synergistic cytotoxicity with Ara-C (MNKI-8e, emodin, metformin and niclosamide), subtoxic concentrations of chemotherapy (PD0332991), and potently antineoplastic treatments that do not damage nonmalignant cells (heteronemin or hydroxyurea + azidothymidine).
