Blood Rev 2024:101226. [PMID: 39164126 DOI: 10.1016/j.blre.2024.101226] [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: 06/20/2024] [Revised: 08/07/2024] [Accepted: 08/07/2024] [Indexed: 08/22/2024]
Abstract
Measurable residual disease (MRD)-testing is used in many haematological cancers to estimate relapse risk and to direct therapy. Sometimes MRD-test results are used for regulatory approval. However, some people including regulators wrongfully believe results of MRD-testing are highly accurate and of proven efficacy in directing therapy. We review MRD-testing technologies and evaluate the accuracy of MRD-testing for predicting relapse and the strength of evidence supporting efficacy of MRD-guided therapy. We show that at the individual level MRD-test results are often an inaccurate relapse predictor. Also, no convincing data indicate that increasing therapy-intensity based on a positive MRD-test reduces relapse risk or improves survival. We caution against adjusting therapy-intensity based solely on results of MRD-testing.

Abstract
Despite significant progress in targeted therapy for acute myeloid leukemia (AML), clinical outcomes are disappointing for elderly patients, patients with less fit disease characteristics, and patients with adverse disease risk characteristics. Over the past 10 years, adaptive T-cell immunotherapy has been recognized as a strategy for treating various malignant tumors. However, it has faced significant challenges in AML, primarily because myeloid blasts do not contain unique surface antigens. The preferentially expressed antigen in melanoma (PRAME), a cancer-testis antigen, is abnormally expressed in AML and does not exist in normal hematopoietic cells. Accumulating evidence has demonstrated that PRAME is a useful target for treating AML. This paper reviews the structure and function of PRAME, its effects on normal cells and AML blasts, its implications in prognosis and follow-up, and its use in antigen-specific immunotherapy for AML.

Abstract
Background: Acute myeloid leukemia (AML) is a challenging disease with high rates of recurrence. The role of the cancer-related gene GRHL2 in AML has not been widely studied. Methods: Peripheral blood samples were collected from 73 AML patients and 68 healthy controls. Droplet digital PCR was used to detect GRHL2 methylation levels to explore the value of GRHL2 methylation in the diagnosis, treatment response and prognosis of AML. Result: GRHL2 methylation was significantly increased in AML patients (p < 0.01), with high diagnostic accuracy (area under the curve: 0.848; p < 0.001). GRHL2 methylation was correlated with chemotherapy response (p < 0.05) and is an independent prognostic factor for AML (p < 0.05). Conclusion: GRHL2 methylation is expected to serve as a biomarker for diagnosing AML patients and predicting prognosis.

Abstract
Genetic testing has been applied for decades in clinical routine diagnostics of hematological malignancies to improve disease (sub)classification, prognostication, patient management, and survival. In recent classifications of hematological malignancies, disease subtypes are defined by key recurrent genetic alterations detected by conventional methods (i.e., cytogenetics, fluorescence in situ hybridization, and targeted sequencing). Hematological malignancies were also one of the first disease areas in which targeted therapies were introduced, the prime example being BCR::ABL1 inhibitors, followed by an increasing number of targeted inhibitors hitting the Achilles' heel of each disease, resulting in a clear patient benefit. Owing to the technical advances in high-throughput sequencing, we can now apply broad genomic tests, including comprehensive gene panels or whole-genome and whole-transcriptome sequencing, to identify clinically important diagnostic, prognostic, and predictive markers. In this review, we give examples of how precision diagnostics has been implemented to guide treatment selection and improve survival in myeloid (myelodysplastic syndromes and acute myeloid leukemia) and lymphoid malignancies (acute lymphoblastic leukemia, diffuse large B-cell lymphoma, and chronic lymphocytic leukemia). We discuss the relevance and potential of monitoring measurable residual disease using ultra-sensitive techniques to assess therapy response and detect early relapses. Finally, we bring up the promising avenue of functional precision medicine, combining ex vivo drug screening with various omics technologies, to provide novel treatment options for patients with advanced disease. Although we are only in the beginning of the field of precision hematology, we foresee rapid development with new types of diagnostics and treatment strategies becoming available to the benefit of our patients.

Abstract
Although final classification of acute myeloid leukemia (AML) integrates morphologic, cytogenetic, and molecular data, flow cytometry remains an essential component of modern AML diagnostics. Here, we review the current role of flow cytometry in the classification, prognostication, and monitoring of AML. We cover immunophenotypic features of key genetically defined AML subtypes and their effects on biological and clinical behaviors, review clinically tractable strategies to differentiate leukemias with ambiguous immunophenotypes more accurately and discuss key principles of standardization for measurable residual disease monitoring. These advances underscore flow cytometry's continued growth as a powerful diagnostic, management, and discovery tool.

Abstract
Measurable residual disease (MRD) is a powerful prognostic factor in acute myeloid leukemia (AML). However, pre-treatment molecular predictors of immunophenotypic MRD clearance remain unclear. We analyzed a dataset of 211 patients with pre-treatment next-generation sequencing who received induction chemotherapy and had MRD assessed by serial immunophenotypic monitoring after induction, subsequent therapy, and allogeneic stem cell transplant (allo-SCT). Induction chemotherapy led to MRD- remission, MRD+ remission, and persistent disease in 35%, 27%, and 38% of patients, respectively. With subsequent therapy, 34% of patients with MRD+ and 26% of patients with persistent disease converted to MRD-. Mutations in CEBPA, NRAS, KRAS, and NPM1 predicted high rates of MRD- remission, while mutations in TP53, SF3B1, ASXL1, and RUNX1 and karyotypic abnormalities including inv (3), monosomy 5 or 7 predicted low rates of MRD- remission. Patients with fewer individual clones were more likely to achieve MRD- remission. Among 132 patients who underwent allo-SCT, outcomes were favorable whether patients achieved early MRD- after induction or later MRD- after subsequent therapy prior to allo-SCT. As MRD conversion with chemotherapy prior to allo-SCT is rarely achieved in patients with specific baseline mutational patterns and high clone numbers, upfront inclusion of these patients into clinical trials should be considered.

Measurable residual disease by flow cytometry in acute myeloid leukemia is prognostic, independent of genomic profiling. Leuk Res 2022; 123:106971.

Abstract
Measurable residual disease (MRD) assessment provides a potent indicator of the efficacy of anti-leukemic therapy. It is unknown, however, whether integrating MRD with molecular profiling better identifies patients at risk of relapse. To investigate the clinical relevance of MRD in relation to a molecular-based prognostic schema, we measured MRD by flow cytometry in 189 AML patients enrolled in ECOG-ACRIN E1900 trial (NCT00049517) in morphologic complete remission (CR) (28.8 % of the original cohort) representing 44.4 % of CR patients. MRD positivity was defined as ≥ 0.1 % of leukemic bone marrow cells. Risk classification was based on standard cytogenetics, fluorescence-in-situ-hybridization, somatic gene analysis, and sparse whole genome sequencing for copy number ascertainment. At 84.6 months median follow-up of patients still alive at the time of analysis (range 47.0-120 months), multivariate analysis demonstrated that MRD status at CR (p = 0.001) and integrated molecular risk (p = 0.0004) independently predicted overall survival (OS). Among risk classes, MRD status significantly affected OS only in the favorable risk group (p = 0.002). Expression of CD25 (α-chain of the interleukin-2 receptor) by leukemic myeloblasts at diagnosis negatively affected OS independent of post-treatment MRD levels. These data suggest that integrating MRD with genetic profiling and pre-treatment CD25 expression may improve prognostication in AML.

Abstract
Background Relapse remains the primary cause of death after hematopoietic cell transplantation (HCT) for acute leukemia. The ability to identify minimal/measurable residual disease (MRD) via the blood could identify patients earlier when immunologic interventions may be more successful. We evaluated a new test that could quantify blood tumor mRNA as leukemia MRD surveillance using droplet digital PCR (ddPCR). Methods The multiplex ddPCR assay was developed using tumor cell lines positive for the tumor associated antigens (TAA: WT1, PRAME, BIRC5), with homeostatic ABL1. On IRB-approved protocols, RNA was isolated from mononuclear cells from acute leukemia patients after HCT (n = 31 subjects; n = 91 specimens) and healthy donors (n = 20). ddPCR simultaneously quantitated mRNA expression of WT1, PRAME, BIRC5, and ABL1 and the TAA/ABL1 blood ratio was measured in patients with and without active leukemia after HCT. Results Tumor cell lines confirmed quantitation of TAAs. In patients with active acute leukemia after HCT (MRD+ or relapse; n=19), the blood levels of WT1/ABL1, PRAME/ABL1, and BIRC5/ABL1 exceeded healthy donors (p<0.0001, p=0.0286, and p=0.0064 respectively). Active disease status was associated with TAA positivity (1+ TAA vs 0 TAA) with an odds ratio=10.67, (p=0.0070, 95% confidence interval 1.91 - 59.62). The area under the curve is 0.7544. Changes in ddPCR correlated with disease response captured on standard of care tests, accurately denoting positive or negative disease burden in 15/16 (95%). Of patients with MRD+ or relapsed leukemia after HCT, 84% were positive for at least one TAA/ABL1 in the peripheral blood. In summary, we have developed a new method for blood MRD monitoring of leukemia after HCT and present preliminary data that the TAA/ABL1 ratio may may serve as a novel surrogate biomarker for relapse of acute leukemia after HCT.

Abstract
PURPOSE OF REVIEW Disease relapse remains the most common cause of death among patients with acute myeloid leukemia (AML) following induction therapy and allogeneic hematopoietic cell transplant (allo-HCT). Prolonging the duration of remission with minimal nonrelapse mortality risk is an area of unmet need for AML patients. RECENT FINDINGS In QUAZAR AML-001 study, the oral azacitidine analogue CC-486 demonstrated an overall survival (OS) benefit when given as postremission therapy (PRT) for patients in CR1 that were ineligible to proceed to allo-HCT. Used as maintenance post allo-HCT, CC-486 has also shown safety with encouraging disease-free survival (DFS). Although a recent randomized trial of parenteral azacitidine vs. placebo post allo-HCT failed to show relapse reduction, a subsequent meta-analysis of maintenance studies posttransplant has shown good utility with this approach. Such conflicting results emphasize the need for robust study designs to identify subsets of patients that derive maximal benefits using latest tools to risk stratify relapse risk. SUMMARY PRT with hypomethylating agents is feasible and in select population, there is a survival advantage with CC-486. Better understanding of distinct epigenetic and immunomodulatory properties of azacitidine, holds significant promise to synergize pharmacologic and cellular drivers of disease control as PRT in future AML trials.

Abstract
PURPOSE OF REVIEW Disease relapse remains the major cause of death in patients with acute myeloid leukemia (AML) and is driven by the persistence of leukemic cells following induction chemotherapy or allogeneic hematopoietic cell transplant (allo-HCT). Maintenance therapies to extend the duration of remission and to improve survival have been proposed for several years with mixed results but have experienced a renaissance recently. RECENT FINDINGS The oral hypomethylating agent CC-486 has been the first agent to show an overall survival (OS) benefit compared with observation in AML patients in remission following intensive chemotherapy who are not proceeding to allo-HCT. In the realm of postallo-HCT maintenance therapy, the FLT3 inhibitor sorafenib has yielded superior results in terms of OS and relapse-free survival in randomized trials compared with observation. Several open questions remain regarding patient selection, timing, duration and safety of maintenance therapies. Various targeted agents are currently tested in clinical trials and could potentially enable an even more individualized therapeutic approach. SUMMARY Maintenance therapies following intensive chemotherapy or allo-HCT offer a new therapeutic paradigm for an increasing number of AML patients and have been shown to result in an OS benefit in selected patients.

Abstract
Nearly four decades after their conceptualization, antibody-based therapies are slowly being added to the treatment landscape of acute myeloid leukemia (AML). While the antibody-drug conjugate gemtuzumab ozogamicin is the only antibody-based therapy that has been approved for AML treatment thus far, several bispecific antibodies have been developed and shown early encouraging results. Bispecific antibodies comprise a wide variety of constructs that share the common concept of simultaneous binding of a surface target on malignant cells and most commonly CD3 on T cells leading to an endogenous, HLA-independent, immune response against malignant cells. However, the use of bispecific antibodies in AML has been limited by the absence of highly specific leukemia-associated antigens leading to on-target, off-leukemia side effects as well as reduced efficacy due to antigen escape. Herein, we discuss the history and evolution of bispecific T cell engagers as well as various adaptations such as dual affinity retargeting antibodies, bi- and tri-specific killer engager antibodies. Common side effects including cytokine release syndrome and management thereof are highlighted. Lastly, we expound on the future direction and integration of such antibody-based therapies with other immunotherapies (programmed cell death-1 inhibitors and chimeric antigen receptor T cells).

Abstract
Complete remission (CR) has long been the critical therapeutic response in acute myeloid leukemia (AML). However, "less than CR" responses have been and continue to be proposed to define clinically meaningful post-therapy outcomes. These responses include CR with incomplete recovery (CRi), CR with incomplete platelet recovery (CRp) and, most recently, CR with partial hematologic recovery (CRh), which has been introduced and subsequently used for regulatory approval. However, the clinical benefits associated with "less than CR" responses have primarily been evaluated in the context of intensive therapies. In an era with sophisticated measurable residual disease (MRD) assessments, including flow-based, cytogenetic and molecular techniques, and an increase in "targeted", non-intensive therapies, the clinical value of responses that are "less than CR" must be reevaluated. Improvements in the rate of CR has not always led to improvements in OS among older patients. As such, MRD techniques might help define a more stringent response criterion (MRD-negative CR) that might better correlate with OS and should be incorporated in future clinical trials. Here we discuss the evolution of CR and "less than CR" responses, data regarding their clinical benefits, and considerations relevant to response assessments with newer therapies.

Abstract
The treatment of acute myeloid leukaemia (AML) and myelodysplastic syndrome (MDS) has seen dramatic advances with the approval of multiple novel agents in recent years. However, unlike solid malignancies, immune checkpoint inhibitors have yet to garner regulatory approval in AML and MDS with recent randomized clinical trials yielding only underwhelming results. Novel targets have been explored in early phase clinical trials with impressive results leading to ongoing subsequent controlled trials. However, major challenges in the field remain such as the validation of predictive genetic, molecular, and immunophenotypic biomarkers, optimization of clinical trial design, and the identification of novel synergistic combination therapies. Herein, we review recent clinical trial data focusing on randomized clinical trials and highlight limitations of the currently available evidence in an effort to suggest options for advancing the field.

Abstract
Isolated myeloid sarcoma (MS) is a rare malignancy in which myeloid blast forms tumors at various locations while the bone marrow (BM) remains cytomorphologically free from disease. We analyzed isolated MS from four patients and their BMs at initial diagnosis and follow-up, using a custom next-generation sequencing (NGS) panel. We observed possible clonal evolution and a clonal hematopoiesis of indeterminate potential (CHIP)-like finding in the BM of one of three cases with detectable mutations. Clinical presentation of one patient suggested extramedullary confined homing of blasts to distal sites in the relapse situation still sparing the BM. In summary, our findings shall motivate future work regarding signals of extramedullary blast trafficking and clonal evolution in MS.

Abstract
INTRODUCTION All current treatment strategies for myeloproliferative neoplasms (MPN) patients with the exception of allogeneic stem cell transplant (ASCT) are continuously administered. Treatment approaches that reduce the degree of minimal residual disease (MRD) might permit possible drug holidays or potential cures. AREA COVERED Authors discuss the presently available agents and those that are under clinical development that might induce a state of MRD and can be administered intermittently. Data extracted from a comprehensive search of peer review literature performed in Pubmed as well as information presented in scientific meetings. EXPERT OPINION Currently, the only potential curative treatment for MPN is ASCT. ASCT requires a period of intense treatment but ultimately allows the patient to enjoy a period independent of continued treatment. There is evidence that intermittent use of busulfan or prolonged use of IFN-α can induce hematological remissions that are sustained for prolonged periods of time, allowing for drug holidays. The experimental drug Imetelstat is a promising drug that has been reported to prolong survival in very high-risk myelofibrosis patients after a limited period of time of administration. New experimental drugs and drug combinations that target the malignant clone and/or microenvironmental abnormalities have the potential to eliminate MRD, which might allow for drug holidays and reduction in the duration of therapy.

Abstract
Mutations in the tumor suppressor gene TP53 are detected in 5-10% of patients with acute myeloid leukemia (AML) and myelodysplastic syndromes. TP53 mutations have been associated with complex karyotypes, therapy-related malignancies, lower response rates to cytotoxic chemotherapy, and an overall adverse prognosis. In this single-center retrospective study, we analyzed the clinicopathologic characteristics and outcomes of 83 patients with TP53-mutated myeloid malignancies treated at Yale Cancer Center between 9/2015 and 5/2019. Complex karyotypes (n = 75; 90%) and therapy-related malignancies (n = 32; 39%) were common. Median overall survival (OS) was 7.6 months. Intensive chemotherapy did not improve OS compared to lower-intensity treatment for AML patients. Patients who underwent allogeneic hematopoietic stem cell transplant (alloHSCT) had a significantly longer median OS, despite relatively limited follow-up. In conclusion, our data confirm the limited efficacy of intensive chemotherapy approaches for TP53-mutated patients with myeloid neoplasms and suggest that a minority of patients achieve long-term survival with alloHSCT.

Abstract
For most patients with higher-risk myelodysplastic syndromes (HR-MDS) the hypomethylating agents (HMA) azacitidine and decitabine remain the mainstay of therapy. However, the prognosis mostly remains poor and aside from allogeneic hematopoietic stem cell transplantation no curative treatment options exist. Unlike acute myeloid leukemia, which has seen a dramatic expansion of available therapies recently, no new agents have been approved for MDS in the United States since 2006. However, various novel HMAs, HMA in combination with venetoclax, immune checkpoint inhibitors, and targeted therapies for genetically defined patient subgroups such as APR-246 or IDH inhibitors, have shown promising results in early stages of clinical testing. Furthermore, the wider availability of genetic testing is going to allow for a more individualized treatment of MDS patients. Herein, we review the current treatment approach for HR-MDS and discuss recent therapeutic advances and the implications of genetic testing on management of HR-MDS.
