Abstract
Very few data are available about hypomethylating agent (HMA) efficiency in core binding factor acute myeloid leukemias (CBF-AML). Our main objective was to evaluate the efficacy and safety of HMA in the specific subset of CBF-AML. Here, we report the results of a multicenter retrospective French study about efficacy of HMA monotherapy, used frontline or for R/R CBF-AML. Forty-nine patients were included, and received a median of 5 courses of azacitidine (n = 46) or decitabine (n = 3). ORR was 49% for the whole cohort with a median time to response of 112 days. After a median follow-up of 72.3 months, median OS for the total cohort was 10.6 months. In multivariate analysis, hematological relapse of CBF-AML at HMA initiation was significantly associated with a poorer OS (HR: 2.13; 95%CI: 1.04-4.36; p = 0.038). Responders had a significantly improved OS (1-year OS: 75%) compared to non-responders (1-year OS: 15.3%; p < 0.0001). Hematological improvement occurred for respectively 28%, 33% and 48% for patients who were red blood cell or platelet transfusion-dependent, or who experienced grade 3/4 neutropenia at HMA initiation. Adverse events were consistent with the known safety profile of HMA. Our study highlights that HMA is a well-tolerated therapeutic option with moderate clinical activity for R/R CBF-AML and for patients who cannot handle intensive chemotherapy.

Abstract
Patients with relapsed or refractory (R/R) acute myeloid leukemia (AML) often exhibit limited responses to traditional chemotherapy, resulting in poor prognosis. The combination of venetoclax (VEN) with hypomethylating agents has been established as the standard treatment for elderly or medically unfit AML patients unable to undergo intensive chemotherapy. Despite this, the availability of novel VEN-based therapies specifically tailored for those with R/R AML remains scarce. Here, we provide a comprehensive overview of the latest data presented at the 65th American Society of Hematology Annual Meeting, shedding light on the progress and efficacy of VEN-based therapies for R/R AML.

Abstract
Objective: To investigate the efficacy and safety of combining venetoclax (VEN) with hypomethylated drugs (HMA) in the treatment of higher-risk (IPSS-R score >3.5) myelodysplastic syndromes (MDS) . Methods: From March 2021 to December 2022, forty-five MDS patients with intermediate and high risk were treated with VEN in combination with HMAs. Clinical data were collected and analyzed retrospectively, including gender, age, MDS subtype, IPSS-R score, treatment regimen, and efficacy, etc. Kaplan-Meier method and Cox regression model were used to analyze univariate and multivariate of survival prognosis. Results: ①Forty-five patients with MDS, including ninety-one percent were classified as high or very high risk. According to the 2023 consensus proposal for revised International Working Group response criteria for higher-risk MDS, the overall response rate (ORR) was 62.2% (28/45), with the complete response rate (CR) was 33.3% (15/45). For twenty-five naïve MDS, the ORR was 68% (17/25) and the CR rate was 32% (8/25). In nonfirst-line patients, the ORR and CR were 55% (11/20) and 35% (7/20) respectively. The median cycle to best response was 1 (1-4). ②With a median followup of 189 days, the median overall survival (OS) time was 499 (95% confidence interval, 287-711) days, and most patients died from disease progression. Responders had a significantly better median OS time than nonresponders (499 days vs 228 days, P<0.001). Multifactor analysis revealed that IPSS-R score and response to treatment were independent prognostic factors for OS; the presence of SETBP1 gene mutations was associated with a longer hospital stay (51.5 days vs 27 days, P=0.017) . Conclusions: There is clinical benefit of venetoclax in combination with hypomethylated agents in patients with higher-risk MDS, but adverse events such as severe hypocytopenia during treatment should be avoided.

Abstract
Recent developments in high-risk Myelodysplastic Neoplasms (HR MDS) treatment are confronted with challenges in study design due to evolving drug combinations with Hypomethylating Agents (HMAs). The shift from the International Prognostic Scoring System (IPSS) to its molecular revision (IPSS-M) has notably influenced research and clinical practice. Introducing concepts like the MDS/AML overlap complicate classifications and including chronic myelomonocytic leukemia (CMML) in MDS studies introduces another layer of complexity. The International Consortium for MDS emphasizes aligning HR MDS criteria with the 2022 ELN criteria for AML. Differences in advancements between AML and MDS treatments and hematological toxicity in HR MDS underline the importance of detailed trial designs. Effective therapeutic strategies require accurate reporting of adverse events, highlighting the need for clarity in criteria like the Common Terminology Criteria for Adverse Events (CTCAE). We provide an overview on negative clinical trials in HR MDS, analyze possible reasons and explore possibilities to optimize future clinical trials in this challenging patient population.

Abstract
We report results of a 65-year-old patient with lower-risk myelodysplastic syndrome and multilineage dysplasia treated with hypomethylating agents. After failure of erythropoietin and thalidomide, the patient received azacitidine and achieved hematological remission for 95 months. In 2016, the treatment was switched to decitabine with promising results. These data showed that azacitidine used as a third-line treatment resulted in an exceptionally long-lasting positive hematological response after standard first- and second-line therapies had failed. Additionally, the patient experienced a good quality of life with no complications related to profound cytopenia, and continues to do so at the time of this report's preparation.

Abstract
Near early T-cell precursor acute lymphoblastic leukemia (ETP-ALL) is a rare hematologic malignancy, for which second line therapeutic options are limited. T-cell leukemias are also rarely associated with leukemia cutis, which is more often seen in leukemias of myeloid origin. We present the case of an adult male diagnosed with near ETP-ALL, with IDH2 and DNMT3A mutations, suggestive of a myeloid origin, and leukemia cutis. After the patient progressed on hyper-CVAD and nelarabine, we treated him with the BCL-2 inhibitor venetoclax and the hypomethylating agent decitabine. The regimen induced a rapid bone marrow response and resolution of the leukemia cutis.

Abstract
Combining venetoclax with the hypomethylating agents azacitidine or decitabine has shown high complete response rates (60-70 %) in newly diagnosed (ND) acute myeloid leukemia (AML). However, studies addressing the efficacy of this approach in relapsed/refractory (R/R) AML remain limited. We conducted a retrospective analysis on patients treated with venetoclax-based therapy at a single institution. Objective response rates (ORR) and overall survival (OS) were assessed using logistic regression and Cox regression models, respectively. The total study population exhibited an ORR of 64 % with a complete remission at 34 %, complete remission with incomplete count recovery at 19%, and morphologic leukemia free state at 11 %. Patients with ND AML had a better ORR (71 %) compared to R/R AML (55 %), but the difference was not statistically significant. Median OS for the overall population was 14.4 months (range: 2-26 months). In the ND group, patients had a longer 6-month OS (82 % vs. 55 % in R/R AML), while both cohorts showed similar 12- and 24-month OS. Factors such as the hypomethylating agent chosen, adverse cytogenetics, TP53 mutations, prior hypomethylating agent use, and stem cell transplant status did not significantly affect ORR or OS. These findings support the effectiveness of venetoclax-based treatments in ND and R/R AML.

Abstract
Venetoclax (VEN)-based regimens are the standard of care for elderly or unfit patients with newly diagnosed (ND) acute myeloid leukemia (AML). Some single-arm studies have implied that hypomethylating agents (HMAs) plus priming regimens may potentially provide an alternative therapeutic approach, owing to encouraging efficacy seen. However, no comparative data exists yet regarding these two treatment approaches. In this retrospective multi-center cohort study, we enrolled 294 ND AML patients, allocating 167 to the HMA + priming group and 127 to the VEN-based group. Treatment response and overall survival (OS) were compared between groups. Molecular subgroup analyses were also conducted. With a median of two cycles for HMA + priming group, the overall response (ORR) was 65.3%, including 55.1% complete remission (CR), 9.6% CR with incomplete hematologic recovery (CRi) and 0.6% morphologic leukemia-free state (MLFS). With a median of two cycles for VEN-based group, the ORR was 70.9%, including 46.5% CR, 18.9% CRi, and 5.5% MLFS. Response differences (ORR or CR/CRi) between groups were not significant (p > 0.05). With a median follow-up of 10.1 months, median OSs were similar between groups (20.9 vs 16.3 months, p = 0.41). However, VEN regimens demonstrated superior CR/CRi for patients with mutations in FLT3, IDH1/2, and NPM1 compared to HMA + priming (80.0% vs 35.0%, p = 0.01; 90.9% vs 65.5%, p = 0.02; 90.9% and 65.5%, p = 0.02, respectively). In conclusion, HMAs plus modified priming regimens might be a potential alternative therapeutic approach for patients with ND AML, but VEN-based regimens presented predominance in specific molecular subgroups. Molecular characteristics contribute to guiding choice of treatment.

Abstract
PURPOSE OF REVIEW This study aims to review the challenges of treating AML in older patients, the spectrum of genomic aberrancies in this cohort, and discuss treatment options for newly diagnosed AML in this patient population. RECENT FINDINGS Greater understanding of biological underpinnings of AML and availability of newer, effective, targeted therapies have allowed us to move away from intensification of chemotherapy, to prioritize better tolerability while still maintaining efficacy. Increasing knowledge of the genomic complexity and adverse karyotypes in older AML patients drives the need for ongoing investigations of targeted and lower-intensity therapies in the frontline, relapsed/refractory setting, and post-remission.

Abstract
PLK1 is overexpressed in acute myeloid leukemia (AML). A phase 1b trial of the PLK1 inhibitor onvansertib (ONV) combined with decitabine (DAC) demonstrated initial safety and efficacy in patients with relapsed/refractory (R/R) AML. The current study aimed to identify molecular predictors of response to ONV + DAC in R/R AML patients. A total of 44 R/R AML patients were treated with ONV + DAC and considered evaluable for efficacy. Bone marrow (BM) samples were collected at baseline for genomic and transcriptomic analysis (n = 32). A 10-gene expression signature, predictive of response to ONV + DAC, was derived from the leading-edge genes of gene set enrichment analyses (GSEA). The gene signature was evaluated in independent datasets and used to identify associated mutated genes. Twenty percent of the patients achieved complete remission, with or without hematologic count recovery (CR/CRi), and 32% exhibited a ≥50% reduction in bone marrow blasts. Patients who responded to treatment had elevated mitochondrial function and OXPHOS. The gene signature was not associated with response to DAC alone in an independent dataset. By applying the signature to the BeatAML cohort (n = 399), we identified a positive association between predicted ONV + DAC response and mutations in splicing factors (SF). In the phase 1b/2 trial, patients with SF mutations (SRSF2, SF3B1) had a higher CR/CRi rate (50%) compared to those without SF mutations (9%). PLK1 inhibition with ONV in combination with DAC could be a potential therapy in R/R AML patients, particularly those with high OXPHOS gene expression and SF mutations.

Abstract
Myelodysplastic syndromes (MDS) are clonal stem cell diseases that primarily affect the elderly. They are classified into low- and high-risk MDS according to prognostic scoring systems. In high-risk patients, treatment should aim to modify the course of the disease by preventing progression to acute myeloid leukemia, and thus improve survival. Stem cell transplantation remains the only curative treatment when possible, but this concerns a small minority of patients. Treatment is mainly based on hypomethylating agents (HMA). Our understanding of the biology of MDS has led to the development of drugs targeting key cellular processes such as apoptosis or post-translational modifications of proteins, the microenvironment and genetic mutations. Currently, new drugs are mainly tested in combination with HMAs in several clinical trials and, although none has yet obtained marketing authorization, many molecules seem promising.

Abstract
The treatment patterns for patients with newly diagnosed acute myeloid leukemia (AML) were compared between 2013 and 16 and 2021-22 in a real-world setting. A significantly higher proportion of patients age 70 and over received non-intensive therapy (NIT) in 2021-22 as compared with 2013-16 (65 % vs 44 %, p = 0.014), with a corresponding reduction in the proportion receiving either intensive therapy or no antileukemic treatment. Treatment patterns among patients < age 70 were unchanged. The complete response rate in the NIT group was 69 % in 2021-22 vs. 24 % in 2013-16 (p < 0.001); the overall survival (OS) of NIT patients was 11.5 months in 2021-22 vs. 7.8 months in 2013-16. Older patients from rural areas were more likely to decline therapy than those from urban regions. The increase in the proportion of patients opting for NIT may be related to the availability of more effective treatment options. Although outcomes are improving, the OS with NIT remains suboptimal.

Abstract
Acute myeloid leukemia (AML) is associated with a substantial clinical and economic burden. This study characterized the magnitude of this burden following initial treatment with standard or less intensive therapies (hypomethylating agents [HMAs]) and throughout different treatment phases post-remission. The Surveillance, Epidemiology, and End Results (SEER) cancer registry (2007-2016) linked with Medicare beneficiary claims (2007-2015) was analyzed. Patients were ≥ 65 years old with AML who initiated chemotherapy or HMAs and achieved remission. Outcomes included baseline characteristics, treatment patterns, clinical outcomes, healthcare resource utilization (HRU), and costs (2019 United States dollar). Economic impacts were stratified by treatment phase (initial treatment, early post-remission, late post-remission, and post-relapse). Early and late post-remission were defined as treatment initiated ≤ 60 days and > 60 days following initial treatment, respectively. A subgroup analysis of patients receiving only HMAs as initial treatment was also conducted. Overall, 530 patients were included (mean age: 74.1 years; 53.6 % male). In the overall analysis, 68.1 % of patients received post-remission treatment; 31.9% had no post-remission treatment. Mean monthly per patient healthcare costs by treatment phase were $45,747 (initial treatment), $30,248 (early post-remission), $23,173 (late post-remission), and $37,736 (post-relapse), driven predominantly by inpatient visits. The HMA subgroup analysis comprised 71 patients (mean age: 78.8 years; 50.7 % male); mean monthly per patient healthcare costs were highest post-relapse. The economic burden of AML among older patients is substantial across all treatment phases. AML treatments that induce and prolong remission may reduce HRU and the economic burden of disease.

Abstract
BACKGROUND Currently, there is no standard treatment for managing relapse in patients with acute myeloid leukemia and myelodysplastic syndrome (AML/MDS) after allogeneic hematopoietic cell transplantation. Venetoclax-based therapies have been increasingly used for treating post-transplantation relapse of AML. The aim of this systematic review and meta-analysis was to evaluate the efficacy and adverse events of Venetoclax combined with hypomethylating agents (HMAs) for AML/MDS relapse post-transplantation. METHODS We searched PubMed, Web of Science, Excerpta Medica Database, Cochrane Library, and Clinical. gov for eligible studies from the inception to February 2022. The Methodological Index for Non-Randomized Studies was used to evaluate the quality of the included literatures. The inverse variance method calculated the pooled proportion and 95% confidence interval (CI). RESULTS This meta-analysis included 10 studies involving a total of 243 patients. The pooled complete response and complete response with incomplete blood count recovery rate of Venetoclax combined with HMAs for post-transplantation relapse in AML/MDS was 32% (95% CI, 26-39%, I2 = 0%), with an overall response rate of 48% (95% CI, 39-56%, I2 = 37%). The 6-month survival rate was 42% (95% CI, 29-55%, I2 = 62%) and the 1-year survival rate was 23% (95% CI, 11-38%, I2 = 78%). CONCLUSION This study demonstrated a moderate benefit of Venetoclax in combination with HMAs for patients with relapsed AML/MDS post-transplantation (including those who have received prior HMAs therapy), and may become one of treatment options in the future. Large-scale prospective studies are needed to confirm the potential benefit from venetoclax combined with HMAs.

Abstract
Venetoclax (VEN), the first selective Bcl-2 inhibitor, has shown efficacy and safety both as monotherapy and in combination with other agents in the treatment of newly diagnosed acute myeloid leukemia (AML), while its role in relapsed or refractory (R/R) disease is not well defined. Here, we reviewed the latest advances of VEN-based therapy for R/R AML from the 2022 American Society of Hematology (ASH) Annual Meeting, including some novel and encouraging regimes, such as VCA, VAH, and HAM regimes, etc. Further research is still needed to fully understand the optimal use of these agents in R/R AML treatment.

Abstract
BACKGROUND Acute Myeloid Leukemia (AML) and Myelodysplastic Syndrome (MDS) are two closely related blood cancers that are more frequent in older adults. AML is the most common type of adult acute leukemia, and MDS is characterized by ineffective blood cell production and abnormalities in the bone marrow and blood. Both can be resistant to treatment, often due to dysfunction in the process of apoptosis, the body's natural mechanism for cell death. Venetoclax, an orally-administered medication that selectively targets the BCL-2 protein, has shown promise in enhancing treatment sensitivity in some hematological malignancies by reducing the apoptotic threshold. This review aims to evaluate the effectiveness of venetoclax in treating AML and MDS, as well as potential mechanisms of resistance to the medication. METHODS A literature search was conducted utilizing PUBMED to capture all relevant research articles on the use of venetoclax as a therapy for both diseases. The MeSH terms "acute myeloid leukemia", "myelodysplastic syndrome" and "venetoclax" were searched. Furthermore, Clinicaltrials.gov was accessed to ensure the inclusion of all ongoing clinical trials. RESULTS Although Venetoclax showed modest results as a single-agent therapy in AML, venetoclax-based combination therapies? mainly with hypomethylating agents or low-dose cytarabine? yielded significantly positive results. Preliminary results oN the use of venetoclax-based combination therapy with HMA, mainly azacitidine, in unfit high-risk MDS also yielded optimistic results. Identification of mutations for which various drugs have been approved has spurred active investigation of venetoclax in combination trials. CONCLUSION Venetoclax-based combination therapies have been shown to induce rapid responses and increase overall survival in AML patients unfit for intensive chemotherapy. These therapies are also yielding positive preliminary results in high-risk MDS patients in phase I trials. Resistance to venetoclax and drug-related toxicity are two main obstacles that need to be overcome to reap the full benefits of this therapy.

Abstract
PURPOSE OF REVIEW To discuss novel targeted therapies under investigation for treatment of myelodysplastic neoplasms (MDS). RECENT FINDINGS Over the last few years, results of phase 3 trials assessing novel therapies for high-risk MDS have been largely disappointing. Pevonedistat (NEDD-8 inhibitor) and APR-246 (TP53 reactivator) both did not meet trial endpoints. However, early phase trials of BCL-2, TIM3, and CD47 inhibitors have shown exciting data and are currently under phase 3 investigation. Moreover, combination of hypomethylating agents (HMA) with novel therapies targeting the mutational (IDH, FLT3, spliceosome complex) or immune (PD-1/PDL-1, TIM-3, IRAK-4) pathways are being investigated in early phase clinical trials and have shown adequate safety and promising efficacy. Myelodysplastic neoplasms (MDS) are a group of hematopoietic neoplasms defined by cytopenias and morphological dysplasia. They are characterized by clonal proliferation of aberrant hematopoietic stem cells caused by recurrent genetic abnormalities. This leads to ineffective erythropoiesis, peripheral blood cytopenias, abnormal cell maturation, and a high risk of transformation into acute myeloid leukemia (AML). Allogeneic hematopoietic stem cell transplantation is the only curative therapy; however, it is not a suitable option for majority patients due to their age, comorbidities, and the high rate of treatment-related complications. HMAs remain the only FDA-approved treatment option for high-risk MDS. Due to intolerance, primary, and secondary resistance to HMA, there is a large unmet need to develop new safe and effective therapies for patients with MDS. In this review, we focus on the current management strategies and novel therapies in development for treatment of high-risk MDS.

Abstract
Acute myeloid leukemia (AML) is associated with poor outcomes in older adults. A major goal of treatment is to balance quality of life and functional independence with disease control. With the approval of new, more tolerable regimens, more older adults are able to receive AML-directed therapy. Among these options are hypomethylating agents (HMAs), specifically azacitidine and decitabine. HMAs have become an integral part of AML therapy over the last two decades. These agents are used either as monotherapy or nowadays more commonly in combination with other agents such as the Bcl-2 inhibitor venetoclax. Biological AML characteristics, such as molecular and cytogenetic risk factors, play crucial roles in guiding treatment decisions. In patients with high-risk AML, HMAs are increasingly used rather than intensive chemotherapy, although further trials based on a risk-adapted approach using patient- and disease-related factors are needed. Here, we review trials and evidence for the use of HMA monotherapy and combination therapy in the management of older adults with AML. Furthermore, we discuss the use of HMAs and HMA combination therapies in AML, mechanisms of action, their incorporation into hematopoietic stem cell transplantation strategies, and their use in patients with comorbidities and reduced organ function.

Abstract
PURPOSE Venetoclax combined with a hypomethylating agent (HMA) has become the standard of care for elderly/unfit patients with newly diagnosed acute myeloid leukemia (AML). This study is aimed at characterizing the impact of an interdisciplinary team on the length of stay (LOS) of patients with newly diagnosed AML receiving venetoclax with an HMA. METHODS This retrospective observational study included patients with AML who received HMA with venetoclax as an initial treatment between December 2015 and July 2021. The primary outcome was the median LOS during induction stratified by HMA. Secondary outcomes included barriers to hospital discharge, incidence of tumor lysis syndrome (TLS), response rates, and utilization of the institution's prescription assistance program (PAP). RESULTS Seventy-eight patients were included in our analysis: 51 received azacitidine/venetoclax, and 27 received decitabine/venetoclax. The median LOS from therapy initiation was eight days (range 7-38) for the azacitidine group and six days (range 5-26) for the decitabine group. The most common barriers to discharge were transfusion dependence (33 patients, 42.3%) and insurance coverage (12 patients, 15.4%). Twelve patients (15.3%) had tumor lysis syndrome during hospital admission, and 20 (25.6%) were readmitted during induction. Twenty-three patients (29.5%) required financial assistance for AML care, and a pharmacy-led PAP generated approximately $342,646 in cost savings. CONCLUSION The utilization of an interdisciplinary AML team to target early hospital discharge proved to be safe and effective and led to a reduction in costs for the health system. Future research may identify select patients who may be suitable for earlier discharge or outpatient induction.

Abstract
BACKGROUND TP53 mutations, which are present in 5% to 10% of patients with acute myeloid leukemia (AML), are associated with treatment resistance and poor outcomes. First-line therapies for TP53-mutated (TP53m) AML consist of intensive chemotherapy (IC), hypomethylating agents (HMA), or venetoclax combined with HMA (VEN + HMA). METHODS We conducted a systematic review and meta-analysis to describe and compare treatment outcomes in newly diagnosed treatment-naïve patients with TP53m AML. Randomized controlled trials, single-arm trials, prospective observational studies, and retrospective studies were included that reported on complete remission (CR), CR with incomplete hematologic recovery (CRi), overall survival (OS), event-free survival (EFS), duration of response (DoR), and overall response rate (ORR) among patients with TP53m AML receiving first-line treatment with IC, HMA, or VEN + HMA. RESULTS Searches of EMBASE and MEDLINE identified 3006 abstracts, and 17 publications describing 12 studies met the inclusion criteria. Random-effects models were used to pool response rates, and time-related outcomes were analyzed with the median of medians method. IC was associated with the greatest CR rate of 43%, and CR rates were 33% for VEN + HMA and 13% for HMA. Rates of CR/CRi were comparable for IC (46%) and VEN + HMA (49%) but were lower for HMA (13%). Median OS was uniformly poor across treatments: IC, 6.5 months; VEN + HMA, 6.2 months; and HMA, 6.1 months. For IC, the EFS estimate was 3.7 months; EFS was not reported for VEN + HMA or HMA. The ORR was 41% for IC, 65% for VEN + HMA, and 47% for HMA. DoR was 3.5 months for IC, 5.0 months for VEN + HMA, and was not reported for HMA. CONCLUSIONS Despite improved responses seen with IC and VEN + HMA compared to HMA, survival was uniformly poor, and clinical benefits were limited across all treatments for patients with newly diagnosed, treatment-naïve TP53m AML, demonstrating a significant need for improved treatment for this difficult-to-treat population.

Abstract
BACKGROUND The global incidence of myelodysplastic syndromes (MDS) has been estimated as 0.06 to 0.26/100,000. Since their introduction, hypomethylating agents have played a central role in the treatment of MDS, with heterogeneous real-world outcomes. MATERIALS AND METHODS We assessed and synthesized clinical outcomes of azacitidine (AZA) monotherapy in treatment-naïve patients with higher-risk MDS. A systematic literature review was conducted by searching MEDLINE, Embase, and CENTRAL to identify randomized clinical trials (RCTs) and observational studies, both prospective and retrospective, reporting complete remission (CR), partial remission (PR), overall survival (OS), duration of response (DOR), time-to-response (TTR), and myelosuppressive adverse events (AEs) for patients treated with AZA monotherapy. Noncomparative meta-analyses were used to summarize effects. RESULTS The search identified 3250 abstracts, of which 34 publications describing 16 studies (5 RCTs, 3 prospective, and 8 retrospective observational) were included. Across all studies, pooled CR was 16%; PR was 6%; Median OS was 16.4 months; median DOR was 10.1 months; median TTR was 4.6 months. Proportions of grade 3/4 anemia and thrombocytopenia AEs were 10% and 30%. CONCLUSIONS The effectiveness and efficacy of AZA monotherapy-as measured by CR and median OS-was limited. These findings highlight a significant unmet medical need for effective treatments for patients with higher-risk MDS.

Abstract
Background Venetoclax (VEN) in combination with hypomethylating agent (HMA) therapy is a standard treatment option for patients with newly diagnosed acute myeloid leukemia (AML); however, data are limited in the relapsed or refractory (R/R) populations and in those with poor-risk disease. A retrospective review was conducted involving patients with AML who received HMA alone or in combination with VEN (VEN + HMA). Methods VEN + HMA was compared to HMA alone in first-line and R/R settings. Patients were stratified by specific HMA and line of therapy. The primary endpoint was overall response rate (ORR) up to 6 months from start of treatment. Results Fifty-two patients were evaluated for efficacy and 78 patients for safety. ORR was 67% (VEN + HMA) versus 80% (HMA) in the first line and 50% versus 22% in R/R setting. A greater clinical benefit was seen with VEN + HMA compared to HMA in both lines of therapy (first-line: 87% vs. 80%; R/R: 75% vs. 67%). The median duration of response was longer with VEN + HMA first-line, but shorter in the R/R setting compared to HMA (8.3 vs. 7.2 months and 2.5 vs. 3.7 months, respectively). Of the 32 patients who responded to therapy, 63% had a complex karyotype. Survival benefits were greater with VEN + HMA in both lines of therapy, although not statistically significant. Grade 3/4 neutropenia was reported in all patients receiving VEN, and 95% of these patients also experienced grade 3/4 thrombocytopenia. There were three cases of tumor lysis syndrome. Conclusion The addition of VEN to HMA has consistently shown benefit as first-line treatment and may have some benefit in R/R settings as well. Further studies are needed to compare across various lines of treatment and unfavorable disease. Dynamic strategies that improve toxicity management should be considered.

Abstract
In this single center retrospective analysis 76 patients with high-risk (HR) myelodysplastic syndrome (MDS) treated with azacitidine (AZA) were reviewed for response, especially cytogenetic response (cyR) using repeated chromosome banding analyses (CBA) of bone marrow (bm) metaphases and frequent sequential Fluorescence-in-situ Hybridization (FISH) analyses of immunomagnetically enriched CD34 + circulating peripheral blood cells (CD34 +pb-FISH). In total, 526 CD34 +pb-FISH analyses and 236 CBA were examined. Median observation time was 8.45 months, median number of AZA cycles applied was 8, median overall survival (OS) was 14.9 months, 42.1 % of patients responded to therapy according to IWG criteria: 5 complete response (CR), 0 partial response (PR), 12 bmCR, 15 stable disease with hematologic improvement (HI). HI was reached in 36.8 % of patients, 31.5 % became transfusion-independent. By CBA or CD34 +pb-FISH 20.4 % and 31.6 % of patients showed cyR, respectively. HI rate was significantly higher in cytogenetic responders than in non-responders, but there was no impact on OS or leukemia-free-survival. Cytogenetic responders showed significantly better OS than non-responders. Patients with ≥ 6 AZA cycles had significantly better OS than patients with < 6 cycles applied. Karyotype evolution (KE) as a manifestation of cytogenetic progression was diagnosed in 29.5 % and 17.1 % of patients by CBA and CD34 +pb-FISH, respectively. KE was associated with significantly poorer OS and leukemia-free-survival.

Abstract
Acute myeloid leukemia (AML) is an aggressive disease predominantly affecting the elderly population. Although, up to 65% of patients with AML achieve a complete remission with standard induction chemotherapy, the majority of patients will relapse and succumb to the disease. Although maintenance therapy is a component of standard management for various hematological malignancies, such as acute lymphoblastic leukemia (ALL), acute promyelocytic leukemia (APL) or multiple myeloma, past studies investigating the role of maintenance therapy in AML were unable to demonstrate an advantage in overall survival, and therefore, it has not been an established practice in the treatment of AML. For patients, who are not candidates for stem cell transplant, effective AML maintenance therapies are needed in order to reduce the risk of relapse. Over the past decades, many investigators have examined the role of various maintenance strategies in AML; with the intention to prolong remission and overall survival. This review will provide an overview of prior and ongoing approaches and strategies to maintenance therapy for AML.

Abstract
Acute myeloid leukemia (AML) arising from myeloproliferative neoplasms (MPNs) represents a small subtype of secondary AML (sAML). This entity is well known to be associated with poor responses to available treatment options and dismal outcomes. To date, there are no standardized treatment options and there has been very little therapeutic advancement in recent years. This is a stark contrast to other subsets of AML for which there have been significant advances in therapeutic approaches, especially for patients with targetable mutations. We aim to focus our review on the incidence, risk factors for leukemogenesis, pathogenesis, molecular landscape, and emerging therapeutic options in post-myeloproliferative neoplasm acute myeloid leukemia (post-MPN AML).

The phase 1b multicohort KEYNOTE-013 study assessed the safety and antitumor activity of pembrolizumab given at 10 mg/kg/day every 2 weeks for up to 2 years in hematologic malignancies, including myelodysplastic syndromes (MDS) refractory to a hypomethylating agent (HMA). Primary outcomes were safety and objective response rate per International Working Group 2006 criteria. By June 26, 2020, 28 patients were enrolled; median duration of follow-up was 5.6 months (range, 1-78), and 25 patients (89%) had died. Treatment-related adverse events occurred in 10 patients (36%), including 2 (7%) treatment-related discontinuations. No patient achieved complete or partial response. Five patients (19%) had bone marrow complete response, 12 (44%) stable disease, 10 (37%) progressive disease, 6 (22%) cytogenetic response, and 5 (19%) hematologic improvement. Median overall survival (OS) was 6.0 months (95% CI, 4-12); the overall 2-year OS rate was 17%. Pembrolizumab had manageable safety and clinical activity in patients with HMA-refractory MDS.This trial was registered at www.clinicaltrials.gov as #NCT01953692.

Abstract
Decitabine (5-aza-2′-deoxycytidine) is a hypomethylating agent used in the treatment of acute myeloid leukemia (AML). Decitabine inhibits DNA methyltransferases, causing DNA hypomethylation, and leading amongst others to re-expression of silenced tumor suppressor genes. Decitabine is indicated for the treatment of adult patients with newly diagnosed de novo or secondary AML who are not eligible for standard induction chemotherapy. The initial authorization in 2012 was based on the results of the open-label, randomized, multicenter phase 3 DACO-016 trial, and supported by data from the supportive phase 2 open-label DACO-017 trial. Compared with standard care, decitabine significantly improved overall survival, event-free survival, progression-free survival, and response rate. Decitabine was generally well tolerated, offering a valuable treatment option in patients with AML irrespective of age, especially for patients achieving a complete response. Several observational “real-life” studies confirmed these results. In contrast to standard chemotherapy, the presence of adverse-risk karyotypes or TP53 mutations does not negatively impact sensitivity to hypomethylating therapy albeit with lower durability. Data suggest a potential positive effect of decitabine in patients with monosomal karyotype-positive AML. For the time being, decitabine is an appropriate option as monotherapy for patients with AML who are unfit to receive more intensive combination therapies, but emerging data suggest that decitabine-based doublet or triplet combinations may be future treatment options for patients with AML.

Abstract
OPINION STATEMENT The treatment of myelodysplastic syndromes (MDS) begins with risk stratification using a validated tool such as the International Prognostic Scoring System (IPSS) or its revised version (IPSS-R). This divides patients into lower- and higher- risk categories. Although treatment objectives in lower-risk MDS (LR-MDS) have traditionally been directed at improving cytopenias (usually anemia) as well as quality of life, recent data supports a potential role for early intervention in delaying transfusion dependency. In addition, careful individualized risk stratification incorporating clinical, cytogenetic, and mutational data might help identify patients at higher-than-expected risk for progression. Given the need for supportive care with red blood cell (RBC) transfusions leading to iron overload, iron chelation should be considered for patients with heavy transfusion requirements at risk for end-organ complications. For patients with LR-MDS and isolated anemia, no high-risk features, and endogenous erythropoietin (EPO) levels below 500 U/L, erythropoiesis-stimulating agents (ESAs) can be attempted to improve anemia. Some LR-MDS patient subgroups may also benefit from specific therapies including luspatercept (MDS with ring sideroblasts), lenalidomide (MDS with deletion 5q), or immunosuppressive therapy (hypocellular MDS). LR-MDS patients failing the above options, or those with multiple cytopenias and/or higher-risk features, can be considered for oral low-dose hypomethylating agent (HMA) therapy. Alternatively, these patients may be enrolled on a clinical trial with promising agents targeting the transforming-growth factor beta (TGF-β) pathway, the hypoxia-inducible factor (HIF) pathway, telomerase activity, inflammatory signaling, or the splicing machinery. In higher-risk MDS (HR-MDS), therapy seeks to modify the natural history of the disease and prolong survival. Eligible patients should be considered for curative allogeneic hematopoietic stem cell transplantation (aHSCT). Despite promising novel combinations, the HMAs azacitidine (AZA) or decitabine (DAC) are still the standard of care for these patients, with intensive chemotherapy-based approaches being a potential option in a small subset of patients. Individuals who fail to respond or progress after HMA experience dismal outcomes and represent a major unmet clinical need. Such patients should be treated as part of a clinical trial if possible. Experimental agents to consider include venetoclax, myeloid cell leukemia 1 (MCL-1) inhibitors, eprenetapopt, CPX-351, immunotherapies (directed towards CD47, TIM3, or CD70), interleukin-1 receptor-associated kinase 4 (IRAK4) inhibitors, pevonedistat, seclidemstat, and eltanexor. In this review, we extensively discuss the current landscape of experimental therapies for both LR- and HR-MDS.

Abstract
The addition of venetoclax to hypomethylating agents (HMA-V) improved the outcome of patients with newly diagnosed acute myeloid leukemia (AML) ineligible for intensive treatment. The aim of our study was to confirm data reported in literature, in a real-life multicenter experience. We retrospectively evaluated 56 naïve AML patients who received HMA-V at 8 different collaborating Hematology Units in the North-East of Italy, from September 2018 to October 2020. Patients received azacitidine or decitabine at standard dose, adding venetoclax starting from cycle 1-3. The median time-to-response was 2 cycles and composite complete remission rate (CCR) was 67.9%. Thirteen out of 38 responders (34.2%) relapsed, with a median response duration of 13.7 months. Transfusion independence (TI) was obtained in 27 (87.0%) and 28 (90.3%) out of 31 patients for red blood cells and platelets, respectively. Median OS was 12.3 months (95% CI, 8.1-16.5), and median PFS was 11.3 months (95% CI, 4.6-17.9). Cytogenetic risk was the only variable impacting on survival, while no differences were observed stratifying patients by age, bone marrow blasts, WHO classification or type of HMA. In conclusion, our real-life multicenter experience indicates that HMA-V treatment allows achieving good response rates in naïve AML patients, ineligible for intensive chemotherapy.

Abstract
Chronic myelomonocytic leukemia (CMML) is a rare and aggressive myeloid malignancy with overlapped features of myelodysplastic syndromes/myeloproliferative neoplasms. Azacitidine (AZA), a hypomethylating agent, has been approved for the treatment of CMML in China, but real-world data are limited. Medical records of CMML patients who had received subcutaneously injected AZA were reviewed from January 2018 at five participating sites in China. Response was assessed according to the modified International Working Group (IWG 2006) criteria. Between January 2018 and November 2020, a total of 24 patients with CMML were included with a median age of 63 years. Patients received a median of 3 cycles of AZA treatment (range, 1-8). Overall response rate (ORR) was 37.5% (9 of 24); CR rate, PR rate, and mCR/HI rate were 8.3% (n = 2), 8.3% (n = 2), and 20.8% (n = 5), respectively. At a median duration of follow-up of 14.0 months (range 0.0-22.0 months), the median overall survival (OS) was 23.0 months. Univariate analysis revealed that ≥ 3 cycles of treatment was significantly associated with a higher 1-year OS rate compared with < 3 cycles of AZA treatment. Treatment was generally well-tolerated. The most common (> 10%) AEs were thrombocytopenia (n = 7, 29.2%), pneumonitis (n = 4, 16.7%) and fever (n = 3, 12.5%). This study provides valuable real-life data in China on the treatment schedules, efficacy and safety of AZA in the treatment of CMML.

Abstract
PURPOSE OF REVIEW Treatment of elderly patients with acute myeloid leukemia is a known challenge for hematologists due to patient diversity, heterogeneous disease biology, and a rapidly evolving treatment landscape. Here, we highlight the importance of determining fitness, review the latest therapeutic developments, and discuss clinical scenarios to provide guidance on individualized treatment for older AML patients. RECENT FINDINGS Several factors, like age, performance status, and comorbidities, play a role in fitness and are associated with outcome. Comorbidity scoring systems and geriatric assessments are tools to help physicians select the most appropriate treatment for each patient. The addition of venetoclax, targeted therapy with IDH1/2 and FLT3 inhibitors, and enhanced formulas of existing drugs like CPX-351 and oral azacitidine have improved responses and outcomes. New drugs and combination therapies have increased the therapeutic options for elderly AML patients but determination of fitness and disease biology is essential to select patient-tailored treatments.

Abstract
OBJECTIVE This study analyzes the effects of lifestyle, nutrition, and diets on the status and risks of apparent (symptomatic) COVID-19 infection in Iranian families. MATERIALS AND METHODS A relatively extensive questionnaire survey was conducted on more than 20,000 Iranian families (residing in more than 1000 different urban and rural areas in the Islamic Republic of Iran) to collect the big data of COVID-19 and develop a lifestyle dataset. The collected big data included the records of lifestyle effects (e.g. nutrition, water consumption resources, physical exercise, smoking, age, gender, health and disease factors, etc.) on the status of COVID-19 infection in families (i.e. residents of homes). Therefore, an online self-reported questionnaire was used in this retrospective observational study to analyze the effects of lifestyle factors on the COVID-19 risks. The data collection process spanned from May 10, 2020 to March 19, 2021 by selecting 132 samples from more than 40 different social network communities. RESULTS The research results revealed that food and water sources, which contain some natural hypomethylating agents, mitigated the risks of apparent (symptomatic) COVID-19 infection. Furthermore, the computations on billions of permutations of nutrition conditions and dietary regime items, based on the data collected from people's diets and infection status, showed that there were many dietary conditions alleviating the risks of apparent (symptomatic) COVID-19 infection by 90%. However, some other diets tripled the infection risk. CONCLUSION Some natural hypomethylating agents in food, water, and environmental resources are against the spread and risks of COVID-19.

Abstract
Myelodysplastic syndrome is a heterogeneous disease with survival probabilities ranging from a few months to several years. Allogeneic hematopoietic cell transplantation (HCT) remains the only curative treatment. Although access (up to 75 years) and outcome of HCT have improved steadily in recent years, high relapse rates and, to a lower extent, treatment related mortalities are a persisting problem. Reduction of tumor burden before HCT has been shown to decrease relapse incidence and often overall survival (OS) in hematological malignancies but the role of pretransplant therapy in MDS remains controversial. We reviewed the role of pretransplant therapy on outcome in MDS patients. No prospective randomized trial addressed this issue so far. Retrospective studies have shown that pretransplant therapy reduces the risk of relapse, but does not improve survival. In addition, registry studies from diagnosis with standard protocols are proposed in order to exclude patient selection. With the availability of new, more effective and low-toxicity therapies, it may be possible to achieve a significant improvement of OS in the future.

Abstract
Myelodysplastic syndromes (MDS) represent a cluster of genetically and phenotypically heterogeneous hematological disorders. While molecularly targeted therapies have entered the standard of care for other hematological malignancies like acute myeloid leukemia, this approach has been elusive in MDS. This review has summarized recent evidence to determine how molecular aberrations can be used to guide therapy in MDS and improve outcomes among patients.

Abstract
Hypomethylating agents (HMAs) are effective therapies in myelodysplastic syndromes (MDS), but allogeneic hematopoietic stem cell transplantation (allo-HSCT) is the only way to cure MDS. According to the current literature, it is difficult to confirm whether HMAs bridging therapy is beneficial for MDS patients receiving allo-HSCT. Therefore, we tried to evaluate the effect of HMAs on long-term survival of the MDS patients. Databases, including PubMed, Embase Ovid, and the Cochrane Library, were searched for studies published up to January 10, 2021. Patients who accepted HMAs bridging to allo-HSCT were defined as experimental group, while patients who received the best supportive care (BSC) before allo-HSCT were control group. Overall survival (OS) was the primary end point. Seven studies were included in the final analysis. The final results showed no OS differences between patients accepted HMAs before allo-HSCT and those received BSC (HR = 0.86, 95% CI: 0.64-1.15, p = 0.32), indicating that MDS patients' long-term survival did not benefit from HMAs bridging therapy before allo-HSCT. This conclusion needs to be further verified by a large number of prospective randomized controlled trials, which have guiding significance for the treatment of MDS patients.

Abstract
Recurrence in acute myeloid leukemia (AML) is a major barrier in patients who achieve complete remission after induction of remission and consolidation therapy and desire long-term survival. Allogeneic hematopoietic stem cell transplantation lowers recurrence risk in patients; however, recurrence is common even after transplantation. Many maintenance therapies for AML aim to lower recurrence risk; therefore, research has focused on identifying drugs with a tolerable adverse-effect profile. Thus far, many trials of cytotoxic anticancer drugs used in maintenance therapy have showed no improvement in survival rates. In contrast, recent studies on immunomodulation, epigenetics, molecular-targeted drugs, etc. have demonstrated promising results. Therefore, we plan to review various maintenance therapies, such as immunotherapy, demethylating agents, and targeted therapies (including fms-like tyrosine kinase 3 inhibitors in particular) based on the current evidence. Moreover, we describe a new strategy that incorporates the assessment of measurable minimal residual disease.

Abstract
Myelodysplastic syndrome (MDS) is a group of clonal diseases caused by the accumulation of genetic mutations. The outcome of MDS extremely varies, with an overall survival ranging from just a few months to years. Therefore, accurate classification and prognostic scoring are essential. Patients with MDS are generally divided into two risk groups. For low-risk patients, the treatment goal is to improve ineffective hematopoiesis and quality of life. Meanwhile, in high-risk patients, treatment aims to extend survival and prevent progression to leukemia. To date, different guidelines recommend azacytidine, which is a hypomethylating agent, as the initial treatment. This is the only therapy associated with a significant survival in high-risk patients who are not eligible for hematopoietic stem cell transplantation. However, the response rate is only about 40%, and responses are mostly transient. Recent advancements in sequencing technologies have improved our understanding of the molecular pathogenesis of MDS by identifying somatic mutations in almost each patient with MDS. The high phenotypic and clinical heterogeneity of patients with MDS is primarily based on genetics. Due to a high degree of heterogeneity, the treatment policy for patients with MDS is still challenging. In this review, we will discuss the current treatment strategies for MDS in Japan, including future perspectives.

Abstract
Peripheral T-cell Lymphomas (PTCL) are a heterogenous group of aggressive non-Hodgkin lymphomas that are far less sensitive to chemotherapy than their B-cell counterparts. Despite their poor prognosis, they are treated similarly to most aggressive B-cell lymphomas, heavily relying on CHOP or CHOP-like combination chemotherapy irrespective of their different subtypes or biology. The last decade has seen the emergence of many targeted therapies that include histone deacetylase inhibitors, hypomethylating agents, monoclonal antibodies and PIK3 inhibitors, among others. However, prognosis remains poor especially in the relapsed/refractory setting. Using an extensive pubmed search, the authors will be summarizing the different trials that led to these approved targeted agents as well as novel combination strategies. The fundamental recognition that different subtypes of PTCL have specific biological features that drive not only proliferation, but also responses to different treatment approaches, should be informing the design of future clinical trials.

Abstract
Myelodysplastic syndromes (MDS) are a group of heterogeneous clonal hematopoietic stem cell disorders. The 2020 Surveillance, Epidemiology, and End Results data demonstrates the incidence rate of MDS increases with age especially in those greater than 70 years of age. Risk stratification that impact prognosis, survival, and rate of acute myeloid leukemia (AML) transformation in MDS is largely dependent on revised International Prognostic Scoring System along with molecular genetic testing as a supplement. Low risk MDS typically have a more indolent disease course in which treatment is only initiated to ameliorate symptoms of cytopenias. In many, anemia is the most common cytopenia requiring treatment and erythroid stimulating agents, are considered first line. In contrast, high risk MDS tend to behave more aggressively for which treatment should be initiated rapidly with Hypomethylating Agents (HMA) being in the frontline. In those with high risk MDS and eligible, evaluation for allogeneic stem cell transplant should be considered as this is the only potential curative option for MDS. With the use of molecular genetic testing, a personalized approach to therapy in MDS has ensued. As the treatment landscape in MDS continues to flourish with novel targeted agents, we ambitiously seek to improve survival rates especially among the relapsed/refractory and transplant ineligible.

Abstract
BACKGROUND The value of pre-transplant cytoreductive therapy for patients with myelodysplastic syndromes (MDS) is controversial. Here, we conducted a meta-analysis to explore the effects of cytoreduction before transplantation. METHODS PubMed, Embase, Cochrane, and Chinese databases were searched to identify studies comparing post-transplant outcomes in MDS patients receiving different pre-transplant therapy. Pooled hazard ratios (HRs) and 95 % confidence intervals (CI) were calculated. RESULTS Eighteen reports were included. Post-transplant outcomes were similar for MDS patients receiving pre-transplant cytoreductive therapy and upfront transplantation in terms of overall survival (OS: HR, 0.92; 95 % CI, 0.79-1.07), relapse-free survival (RFS: HR, 1.18; 95 % CI, 0.94-1.47), cumulative incidence of relapse (CIR: HR, 1.08; 95 % CI, 0.88-1.33), and non-relapse mortality (NRM: HR, 0.93; 95 % CI, 0.74-1.18). Pre-transplant hypomethylating agents (HMAs) and chemotherapy were not different regarding post-transplant OS, RFS, CIR, and NRM. Achieving complete remission (CR) before transplantation was associated with increased RFS (HR, 0.80; 95 %CI, 0.63-1.00) and decreased NRM (HR, 0.53; 95 % CI, 0.32-0.90) when compared with upfront transplantation. CONCLUSIONS Timely transplantation is of great value for MDS patients. Suitable pre-transplant cytoreduction could be used during the search for donors.

Abstract
Activation Induced Cytidine Deaminase Expression in Patients with Myelodysplastic Syndrome and its Relationship with Prognosis and Treatment Background and Aim: Activation induced cytidine deaminase (AID) enables antibody diversity in B lymphocytes. It may also have an effect on MDS pathogenesis by causing somatic mutations and by inducing epigenetic changes in myeloid cells. This study aimed to compare AID expression of MDS patients with healthy controls, of MDS patients in different risk groups and of MDS patients according to their treatment. MATERIALS AND METHODS Total RNA was isolated and complementary DNA (cDNA) was transcribed from the peripheral blood samples of MDS patients and healthy controls. AID and the reference gene HPRT1 were analysed using Quantitative Real-time PCR(QRT-PCR). AID expression relative to HPRT1 was calculated. Patients were classified into "lower risk" and "higher risk" subgroups according to their initial IPSS and IPSS-R scores and their MDS subtypes at the time of study. Patients were also divided into two groups based on receiving treatment with hypomethylating agents. AID expression of different groups were compared using Mann-Whitney U test. RESULTS Thirty MDS patients and thirty healthy controls were included. AID expression in MDS patients was significantly higher compared to healthy controls (p<0.001). There was no significant difference in AID expression of "lower risk" and "higher risk" subgroups of patients. Patients that received hypomethylating agents did not have a significant difference in AID expression compared with patients that did not receive hypomethylating agents. CONCLUSION AID expression is increased in the peripheral blood of MDS patients compared to healthy controls. However, AID expression is not significantly different in "lower risk" and "higher risk" subgroups and in patients treated with hypomethylating agents. Increased AID expression may be an early step in MDS pathogenesis.

Abstract
BACKGROUND Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is the only curative therapy for advanced myelodysplastic syndrome (MDS). However, the value of pretransplant cytoreduction remains debatable. PATIENTS AND METHODS We retrospectively compared the outcomes of upfront transplantation and pretransplant cytoreduction. Of 69 patients, 39 received upfront allo-HSCT and 30 received pretransplant cytoreduction, including chemotherapy (n = 16), hypomethylating agents (HMAs, n = 6), and HMAs with chemotherapy (n = 8). RESULTS The upfront group achieved similar overall survival (OS) and a trend of better progression-free survival (PFS) from diagnosis compared with the cytoreduction group (3-year PFS, 64.0% vs. 44.4%, P = .076). Posttransplant outcomes were comparable between the two groups in terms of OS, relapse-free survival (RFS), cumulative incidence of relapse (CIR), and non-relapse mortality (NRM). In patients with ≥2 mutations, the upfront group achieved better OS and PFS (3-year OS, 100.0% vs. 68.6%, P = .044; 3-year PFS: 92.3% vs. 43.9%, P = .016) than the cytoreduction group. Patients achieving remission in the cytoreduction group had outcomes similar to the upfront group, but those without remission before transplantation had a significantly worse posttransplant OS (3-year OS, 46.7% vs. 75.7%, P = .038). Patients with pretransplant HMAs had better PFS than those with chemotherapy or HMAs plus chemotherapy (P < 0.05). CONCLUSION Compared with pretransplant cytoreduction, upfront allo-HSCT might provide more benefit to some patients with advanced MDS if there are suitable donors. HMAs would be a good alternative during the donor search.

Abstract
PURPOSE To determine the safety of tipifarnib in combination with escalating doses of bortezomib and to determine the maximum tolerated dose in patients with untreated high-risk MDS and oligoblastic acute myeloid leukemia, who were not eligible for intensive therapy. EXPERIMENTAL DESIGN In a "3 + 3″ design, patients received fixed doses of tipifarnib 200 mg bid (days 1-21) and escalating doses of bortezomib (days 8, 15, 22) every 4 weeks in 4-6 cycles. RESULTS The combination was tolerated well by the 11 patients in this study without reaching the maximum tolerated dose. Myelosuppression was the most frequent side effect, but usually of short duration. Interestingly a complete response with or without complete count recovery was observed in three patients and three additional patients had stable disease. The median duration of overall survival was 449 days. Two patients were still alive at 4.0 and 4.3 years, including one patient in continuing CR. CONCLUSIONS The combination of tipifarnib and bortezomib was tolerated well and appeared to have clinical activity in patients with high-risk MDS and AML with low counts of marrow blasts. Our results warrant further evaluation in a phase II study.

Abstract
The introduction of hypomethylating agents (HMAs) 5-azacytidine and decitabine has altered the prognosis of patients with myelodysplastic syndrome (MDS). Over the past few years, the International Prognostic Scoring System (IPSS) and the revised IPSS (IPSS-R) have been used both to define the prognosis of patients with MDS and to select patients to be treated with HMAs. Nevertheless, the prognosis of individual patients with MDS can differ considerably from the one calculated with the use of the above-mentioned prognostic systems. Thus, some patients may achieve long-term survival irrespective of their initial prognostic score. Several factors besides those used to define the IPSS/IPSS-R are analyzed in this review article; these include age and gender, the baseline hematologic characteristics, the comorbidities, the cytogenetic and molecular profile of the patients, as well as their response to treatment with 5-azacytidine. Thus, insight into a more personalized way of managing patients with MDS is given and long-term survival is set as a more realistic goal of treatment with 5-azacytidine.

Abstract
PURPOSE OF REVIEW Secondary AML (s-AML) encompasses a distinct subgroup of AML with either therapy-related AML or AML arising from preexisting myeloid neoplasms. Despite recent advances in the treatment armamentarium of AML, outcomes remain poor in s-AML. The purpose of this review is to highlight distinct characteristics, prognostic factors, and treatment options for patients with s-AML. Further, we focus on a distinctly poor-risk subgroup of s-AML with previous exposure to hypomethylating agents (HMAs) and describe ongoing clinical trials in this patient population. RECENT FINDINGS CPX-351 (liposomal daunorubicin and cytarabine) is the first drug approved for s-AML and represents an advancement in the management of fit patients with this subtype of AML. Despite incremental improvement in remission rates and survival, long-term survival remains poor. Patients who have received prior HMAs for antecedent MDS rarely benefit from CPX-351 or other cytotoxic chemotherapy regimens. The approval of venetoclax in combination with azacitidine has led to a paradigm shift in the management of newly diagnosed older unfit AML patients; however, patients with s-AML and prior HMA therapy were excluded from the landmark randomized phase 3 study. Several early phase clinical trials with both low- and high-intensity therapies are ongoing for s-AML patients, though prior HMA exposure limits inclusion in many of these studies that include HMAs. Patients with s-AML previously treated with an HMA have dismal outcomes with standard therapeutic options and are under-represented in clinical trials. Trials investigating novel therapeutic options in this population are critically needed.

Abstract
BACKGROUND Epigenetic therapy, using hypomethylating agents (HMA), is known to be effective in the treatment of high-risk myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML) patients who are not suitable for intensive chemotherapy and/or allogeneic stem cell transplantation. However, response rates to HMA are low and there is an unmet need in finding prognostic and predictive biomarkers of treatment response and overall survival. We performed global methylation analysis of 75 patients with high-risk MDS and secondary AML who were included in CETLAM SMD-09 protocol, in which patients received HMA or intensive treatment according to age, comorbidities and cytogenetic. RESULTS Unsupervised analysis of global methylation pattern at diagnosis did not allow patients to be differentiated according to the cytological subtype, cytogenetic groups, treatment response or patient outcome. However, after a supervised analysis we found a methylation signature defined by 200 probes, which allowed differentiating between patients responding and non-responding to azacitidine (AZA) treatment and a different methylation pattern also defined by 200 probes that allowed to differentiate patients according to their survival. On studying follow-up samples, we confirmed that AZA decreases global DNA methylation, but in our cohort the degree of methylation decrease did not correlate with the type of response. The methylation signature detected at diagnosis was not useful in treated samples to distinguish patients who were going to relapse or progress. CONCLUSIONS Our findings suggest that in a subset of specific CpGs, altered DNA methylation patterns at diagnosis may be useful as a biomarker for predicting AZA response and survival.

Abstract
With improved safety of the procedure, disease recurrence is now the leading cause of treatment failure when allogeneic hematopoietic cell transplantation is used to treat acute myeloid leukemia (AML). Recent studies suggest that maintenance therapy with hypomethylating agents after standard induction and consolidation chemotherapy prolongs disease-free and possibly overall survival in older patients with AML. While these results argue that hypomethylating agents should likewise prolong remission duration if used as maintenance after allogeneic transplantation for AML, trials to date have failed to show a benefit. This failure may be due, in part, to difficulties in administering the drugs in this setting, and in part, because of an inability to identify those patients most likely to benefit. Realizing the full potential of hypomethylating agents in the management of patients with AML will likely require both improved drug formulations as well as an increased understanding of their mechanism of action in the complex post-allogeneic transplant environment.
