The prognostic value of the peripheral blood cell counts changes during induction chemotherapy in Chinese patients with adult acute myeloid leukemia. Medicine (Baltimore) 2021; 100:e24614.

Abstract
To investigate the prognostic value of the circulating peripheral blood cell counts changes in acute myeloid leukemia (AML) at different time points during induction chemotherapy.We retrospectively analyzed the clinical and laboratory data of 237 newly diagnosed AML patients admitted to Fujian Medical University Union Hospital from January 2011 to December 2014.1. When primitive cells were first removed from the circulating peripheral blood, it was called peripheral blood blast clearance (PBBC). These patients were divided into two groups, according to PBBC. Statistical analysis showed that the day 5 of induction chemotherapy was a better cut-off for PBBC. PBBC≤5 days is defined as early-blast-clearance, while PBBC >6 days is delayed-blast-clearance. There was significant difference between the two groups on complete remission (CR) rate (P = .002), recurrence-free survival (RFS) (P = .026) and overall survival (OS) (P = .001). 2. Multivariate analysis suggested PBBC is an independent prognostic factor for CR, RFS, and OS in AML. Receiver operating characteristic(ROC) curve analysis showed the CR rate of patients with white blood cell count less than 1.25 × 109/L was significantly higher than that of patients with white blood cell count more than 1.25 × 10 9/L (P < .001) at day 5 of induction chemotherapy, but the RFS and OS was no significantly different (P > .05).The dynamics of peripheral blood blast in AML after initiation of induction chemotherapy, especially the time length to achieve PBBC, has important prognostic value for CR rate, RFS, and OS in AML patients. It is a simple and feasible method to evaluate the efficacy of AML.

THE EUROPEAN JOURNAL OF HEALTH ECONOMICS : HEPAC : HEALTH ECONOMICS IN PREVENTION AND CARE 2020; 21:543-555.

Abstract
BACKGROUND Midostaurin (MIDO) combined with standard chemotherapy was approved by the European Medicines Agency in 2017 for the treatment of adults with newly diagnosed FLT3-mutated acute myeloid leukemia (AML) based on results from the RATIFY trial. METHODS A cost-effectiveness model was developed to compare MIDO and standard-of-care (SOC) to SOC alone in France. Per Haute Autorité de Santé (HAS) guidelines, a partitioned survival model with eight health states was used: diagnosis/induction, complete remission, relapse, hematopoietic stem cell transplantation (HSCT), HSCT recovery, post-HSCT recovery (stabilized after HSCT recovery), post-HSCT relapse, and mortality. A lifetime horizon was used beginning at diagnosis with a "cure model,", which assumed natural mortality after trial cut-off. Utility values were obtained from a systematic literature review and included disutilities. Resource utilization was based on HAS clinical guidelines and a survey of French physicians and included drugs and administration, adverse events, routine medical care, HSCT, and end-of-life care costs. RESULTS In RATIFY and after extrapolation, MIDO improved survival compared to SOC, translating into MIDO-treated patients gaining 1.12 life years (LYs) and 1.23 quality-adjusted life years (QALYs) versus SOC. The incremental cost-effectiveness ratio (ICER) for MIDO versus SOC was €68,781 per LY and €62,305 per QALY. Sensitivity analyses showed consistency with base case findings. CONCLUSIONS MIDO represents a clinically significant advancement in the management of newly diagnosed FLT3-mutated AML. In this analysis, MIDO add-on therapy showed gains in LYs and QALYs versus SOC alone and was found to be a cost-effective option at a €100,000 per QALY threshold for end-of-life treatment.

Abstract
AIMS Midostaurin (MIDO) has been proposed for the treatment of newly-diagnosed adult patients with FMS-like tyrosine kinase 3 mutation-positive (FLT3+) acute myeloid leukemia (AML) in combination with standard chemotherapy. The cost-effectiveness of MIDO and standard of care (SOC) followed by MIDO monotherapy was compared to SOC alone for newly-diagnosed FLT3+ AML in the UK. METHODS A partitioned survival model was developed from a UK public healthcare system perspective to compare the cost-effectiveness of MIDO plus SOC and SOC over a lifetime horizon. The model included the following health states/partitions: induction, consolidation, monotherapy, complete remission (CR), relapse, stem cell transplantation (SCT), SCT recovery, and post-SCT recovery. Data on CR, overall survival, and adverse events were obtained from a Phase III clinical trial. Overall survival was extrapolated beyond the trial horizon using a 'cure model' approach and data from the Office for National Statistics. Utilities were identified via a systematic review. Routine care utilization was obtained from the National Institute for Health and Care Excellence single technology appraisal for azacitidine in AML (TA399). The costs of drugs and administration, adverse events, hospitalizations, physician visits, and end-of-life care were incorporated. RESULTS Incremental life years (LYs) and quality-adjusted life years (QALYs) gained by patients on MIDO and SOC versus SOC were 1.67 and 1.47, respectively. At an incremental cost of £54,072 over a lifetime horizon, the ICER was £32,465 per LY and £36,826 per QALY. Sensitivity analyses were generally consistent with the base case findings. CONCLUSIONS With limited treatments in FLT3+ AML, MIDO represents a clinically significant advance in the management of newly-diagnosed AML. Using a threshold of £50,000 per QALY for end-of-life treatment, MIDO was shown to be a cost-effective option for newly-diagnosed FLT3+ AML.

Abstract
Genetic heterogeneity is the basis of clinical heterogeneity among different subtypes of AML. We have successfully cloned a gene related to AML termed FAMLF from a FAB-M2 patient's sample of a second largest AML pedigree. Then we revealed at least three splice variants, named as FAMLF-1, FAMLF-2 and FAMLF-3, and found miR181a1/b1 in the second intron of FAMLF gene family. Higher expression of FAMLF-1 was related to a higher complete remission (CR) rate, but shorter relapse free survival (RFS) in AML. We further found that the FAMLF-1 single nucleotide polymorphism (SNP) haplotype and its expression were positively correlated to clinical parameters of acute myeloid leukemia partially differentiated (FAB-M2) patients, but not FAB non-M2 patients or Acute Monocytic Leukemia (FAB-M5) patients. GTAGG SNP haplotype of FAMLF gene might increase FAB-M2 susceptibility in Han population and act as a useful candidate biomarker for FAB-M2 screening. We also demonstrated that FAMLF-1 gene silencing in FAB-M2 cells could lead to proliferation inhibition, cell cycle G0/G1 phase arrest, and differentiation promotion independent of its intronic miR-181a1, which might be related to Akt/c-Myc pathway. These findings reveal a role of FAMLF-1 as a potential pathogenic gene for FAB-M2.

Abstract
Background Cytogenetic aberrations and gene mutations have long been regarded as independent prognostic markers in AML, both of which can lead to misexpression of some key genes related to hematopoiesis. It is believed that the expression level of the key genes is associated with the treatment outcome of AML. Methods In this study, we analyzed the clinical features and molecular aberrations of 560 newly diagnosed non-M3 AML patients, including mutational status of CEBPA, NPM1, FLT3, C-KIT, NRAS, WT1, DNMT3A, MLL-PTD and IDH1/2, as well as expression levels of MECOM, ERG, GATA2, WT1, BAALC, MEIS1 and SPI1. Results Certain gene expression levels were associated with the cytogenetic aberration of the disease, especially for MECOM, MEIS1 and BAALC. FLT3, C-KIT and NRAS mutations contained conversed expression profile regarding MEIS1, WT1, GATA2 and BAALC expression, respectively. FLT3, DNMT3A, NPM1 and biallelic CEBPA represented the mutations associated with the prognosis of AML in our group. Higher MECOM and MEIS1 gene expression levels showed a significant impact on complete remission (CR) rate, disease free survival (DFS) and overall survival (OS) both in univariate and multivariate analysis, respectively; and an additive effect could be observed. By systematically integrating gene mutational status results and gene expression profile, we could establish a more refined system to precisely subdivide AML patients into distinct prognostic groups. Conclusions Gene expression abnormalities contained important biological and clinical informations, and could be integrated into current AML stratification system.

Abstract
Carcinogenesis cannot be explained only by genetic alterations, but also involves epigenetic processes. Modification of histones by acetylation plays a key role in epigenetic regulation of gene expression and is controlled by the balance between histone deacetylases (HDAC) and histone acetyltransferases (HAT). HDAC inhibitors induce cancer cell cycle arrest, differentiation and cell death, reduce angiogenesis and modulate immune response. Mechanisms of anticancer effects of HDAC inhibitors are not uniform; they may be different and depend on the cancer type, HDAC inhibitors, doses, etc. HDAC inhibitors seem to be promising anti-cancer drugs particularly in the combination with other anti-cancer drugs and/or radiotherapy. HDAC inhibitors vorinostat, romidepsin and belinostat have been approved for some T-cell lymphoma and panobinostat for multiple myeloma. Other HDAC inhibitors are in clinical trials for the treatment of hematological and solid malignancies. The results of such studies are promising but further larger studies are needed. Because of the reversibility of epigenetic changes during cancer development, the potency of epigenetic therapies seems to be of great importance. Here, we summarize the data on different classes of HDAC inhibitors, mechanisms of their actions and discuss novel results of preclinical and clinical studies, including the combination with other therapeutic modalities.

Abstract
INTRODUCTION Acute myeloid leukemia (AML) is the most common adult leukemia. Only a fraction of AML patients will survive with existing chemotherapy regimens. Hence, there is an urgent and unmet need to identify novel targets and develop better therapeutics in AML. In the past decade, the field of sphingolipid metabolism has emerged into the forefront of cancer biology due to its importance in cancer cell proliferation and survival. In particular, acid ceramidase (AC) has emerged as a promising therapeutic target due to its role in neutralizing the pro-death effects of ceramide. Areas covered: This review highlights key information about AML biology as well as current knowledge on dysregulated sphingolipid metabolism in cancer and AML. We describe AC function and dysregulation in cancer, followed by a review of studies that report elevated AC in AML and compounds known to inhibit the enzyme. Expert opinion: AML has a great need for new drug targets and better therapeutic agents. The finding of elevated AC in AML supports the concept that this enzyme represents a novel and realistic therapeutic target for this common leukemia. More effort is needed towards developing better AC inhibitors for clinical use and combination treatment with existing AML therapies.

Abstract
Pharmacological modulation of autophagy has been referred to as a promising therapeutic strategy for cancer. Matrine, a main alkaloid extracted from Sophora flavescens Ait, has antitumour activity against acute myelocytic leukaemia (AML). Whether autophagy is involved in antileukaemia activity of matrine remains unobvious. In this study, we demonstrated that matrine inhibited cell viability and colony formation via inducing apoptosis and autophagy in AML cell lines HL‐60, THP‐1 and C1498 as well as primary AML cells. Matrine promoted caspase‐3 and PARP cleavage dose‐dependently. Matrine up‐regulated the level of LC3‐II and down‐regulated the level of SQSTM1/p62 in a dose‐dependent way, indicating that autophagy should be implicated in anti‐AML effect of matrine. Furthermore, the autophagy inhibitor bafilomycin A1 relieved the cytotoxicity of matrine by blocking the autophagic flux, while the autophagy promoter rapamycin enhanced the cytotoxicity of matrine. Additionally, matrine inhibited the phosphorylation of Akt, mTOR and their downstream substrates p70S6K and 4EBP1, which led to the occurrence of autophagy. In vivo study demonstrated that autophagy was involved in antileukaemia effect of matrine in C57BL/6 mice bearing murine AML cell line C1498, and the survival curves showed that mice did benefit from treatment with matrine. Collectively, our findings indicate that matrine exerts antitumour effect through apoptosis and autophagy, and the latter one might be a potential therapeutic strategy for AML.

Abstract
BACKGROUND Despite recent success toward discovery of more effective anticancer drugs, chemoresistance remains a major cause of treatment failure. There is emerging evidence that epigenetics plays a key role in the development of the resistance. Epigenetic regulators such as histone acetyltransferases (HATs) and histone deacetylases (HDACs) play an important role in gene expression. The latter are found to be commonly linked with many types of cancers and influence cancer development. Overall, histone acetylation is being investigated as a therapeutic target because of its importance in regulating gene expression. This review summarizes mechanisms of the anticancer effects of histone deacetylase (HDAC) inhibitors and the results of clinical studies. RESULTS Different HDAC inhibitors induce cancer cell death by different mechanisms that include changes in gene expression and alteration of both histone and non-histone proteins. Enhanced histone acetylation in tumors results in modification of expression of genes involved in cell signaling. Inhibition of HDACs causes changed expression in 2-10 % of genes involved in important biological processes. The results of experiments and clinical studies demonstrate that combination of HDAC inhibitors with some anticancer drugs have synergistic or additive effects. CONCLUSIONS Even though many biological effects of HDAC inhibitors have been found, most of the mechanisms of their action remain unclear. In addition, their use in combination with other drugs and the combination regime need to be investigated. The discovery of predictive factors is also necessary. Finally, a key question is whether the pan-HDAC inhibitors or the selective inhibitors will be more efficient for different types of cancers.
