Abstract Purpose: Progression to acute myeloid leukemia (AML) from myeloproliferative neoplasms (MPNs) is almost always fatal. To explore the best treatment strategies for this serious complication, we analyzed the survival outcome of patients with MPNs who progressed to AML based on treatment received at our institution. Patients and Methods: A total of 273 patients who were diagnosed with AML secondary to MPNs between 1989 and 2016 were retrospectively analyzed. Progression-free survival (PFS) and overall survival (OS) were calculated. Results: The patients progressed to AML from essential thrombocythemia (ET, N=60), polycythemia vera (PV, N=49), primary myelofibrosis (PMF, N=105), post-ET/PV MF (N=37), and MPN-unclassifiable (N=22). The median age of the patients was 67 (range: 28-92). The median time to AML transformation from MPN diagnosis was 64.5 months (range: 0.9-477.7 months). Complex karyotype was seen in 99 patients at the time of transformation (38%). With a median follow up of 16.5 months (range: 2.7-115.7 months), 247 patients had died (88% from AML, 6% from treatment-related mortality, 6% with other cause including infection and GVHD). Ninety-nine patients received hypomethylating including agent (HMA), 71 a high-dose cytarabine regimen, 52 a low-dose cytarabine regimen, 28 other treatments, and 24 patients did not receive any treatment due deterioration of the patientfs condition or patientfs decision. The median PFS and OS after progression to AML were 2.6 months and 7.0 months, respectively. There was no significant improvement in PFS and OS by date of diagnosis (1989 to 2016). Also, complete response (CR) rate and survival outcome were not significantly different by type of treatment (Figure A) or prior MPN subtype. Overall, 46 patients (27 in CR, 14 not in CR, 4 unknown due to the transplant outside) proceeded to allogeneic transplant (allo-SCT), and the median overall survival after transplant was 15.3 months (6.1-29.4 months). Although it was not statistically significant, patients who achieved a CR before allo-SCT had longer OS than those who received allo-SCT without achieving a CR (35.1 vs 8.9 months; Figure B). Complex karyotype was associated with both shorter PFS (Hazard ratio: 2.2, 95%CI: 1.6-2.9) and OS (Hazard ratio: 2.0, 95%CI: 1.5-2.6). Summary: Survival outcome for AML secondary to MPN remains very poor, and there has been no improvement in survival outcome since 1989. Further studies are urgently needed to test new treatment strategies and to detect residual disease post allo-SCT. Considering dismal outcome after transformation, studies are also needed to explore strategies to prevent this fatal complication.

Abstract Abstract 1003 Poster Board I-25 Introduction: Recently, the cooperative group HOVON-SAKK has refined the prognostic impact of cytogenetic abnormalities in acute myeloid leukemia (AML) by introducing the concept of monosomal karyotype (MK). This consists of ≥ 2 autosomal monosomies or one autosomal monosomy in addition to a structural alteration. In their experience, MK would explain the poor prognosis of AML with a complex karyotype. Objective: To investigate the prognostic impact of MK in patients with primary (de novo) AML enrolled in the Spanish CETLAM group protocols (AML 94/99/03). Also, to determine whether considering MK added predictive value to the cytogenetic classification of the Medical Research Council (MRC). Methods: Retrospective analysis of data from 1149 AML patients. Chromosomal formula was centrally reviewed with karyotypes being classified by the presence of MK and allocated into the MRC risk categories. Complete remission (CR) rate, disease-free survival (DFS) and overall survival (OS) were calculated. Results: The karyotype was assessable in 904 (79%) of the 1149 cases. In 145 of the 904 cases (16%), abnormalities involving CBF gene were detected and in 437 (48%) the karyotype was normal (NK). In 253 (28%) additional patients the karyotype was not monosomal; of them, 61 (24%) belonged to the unfavorable MRC with 17 cases harboring a complex karyotype ≥ 5 abnormalities, 7 cases with rearrangements 3q, 13 cases with -7, 9 cases with 5q abnormalities and 16 cases with t(6;9)). The remaining 69 (7.7%) patients had a MK; of them, 59 (85.5%) were from the unfavorable MRC category and included 43 cases with complex karyotype ≥ 5 abnormalities, 6 cases with rearrangements 3q, 5 cases with -7, 5 cases with alterations of 5q). The following table summarizes the results in terms of CR rate, DFS and OS: Conclusions: The addition of MK to the MRC cytogenetic classification refines the prognostic prediction. In our series, the dismal outcome of patients with MK is confirmed; these patients had worse prognosis than those with adverse cytogenetics without MK. Alternative treatment strategies are mandatory for MK+ patients. Supported in part by grants: GR1-01075, ECO07/90065, PI080672 and RD06/0020/0101.

Percutaneous revascularisation has evolved dramatically in the past few decades. The approach to the management of ischaemic heart disease has changed due to the development of new devices and techniques as well as the availability of new drugs and treatment strategies. Its use in combination with antiplatelet therapies has been essential to protect against stent thrombosis. The length of time this combination therapy is used has been modified in recent years and has been the subject of extensive research. The effect of prolonging the time it is taken or shortening it has been evaluated in different clinical conditions. In practice, the decisions regarding antithrombotic therapy after percutaneous coronary intervention are informed by the patient’s profile and the characteristics of the procedures performed. In this article, we review the use of antiplatelet/anticoagulant therapy after percutaneous coronary intervention focusing on trials and guidelines addressing variable durations for combination regimens and the alternatives.

Abstract The therapeutic approach to the patient with acute myeloid leukemia (AML) currently evolves toward new frontiers. This is particularly apparent from the entree of high-throughput diagnostic technologies and the identification of prognostic and therapeutic targets, the introduction of therapies in genetically defined subgroups of AML, as well as the influx of investigational approaches and novel drugs into the pipeline of clinical trials that target pathogenetic mechanisms of the disease. In Section I, Dr. Bob Löwenberg reviews current issues in the clinical practice of the management of adults with AML, including those of older age. Dr. Löwenberg describes upcoming possibilities for predicting prognosis in defined subsets by molecular markers and reviews experimental strategies to improve remission induction and postinduction treatment. In Section II, Dr. James Griffin reviews the mechanisms that lead to activation of tyrosine kinases by mutations in AML, the consequences of that activation for the cell, and the opportunities for targeted therapy and discusses some examples of developing novel drugs (tyrosine kinase inhibitors) and their effectiveness in AML (FLT3). In Section III, Dr. Martin Tallman describes the evaluation and management of patients with acute promyelocytic leukemia, a notable example of therapeutic progress in a molecularly defined entity of leukemia. Dr. Tallman focuses on the molecular genetics of APL, current curative treatment strategies and approaches for patients with relapsed and refractory disease. In addition, areas of controversy regarding treatment are addressed.

Abstract Patients with acute myeloid leukemia (AML) are often exposed to broad-spectrum antibiotics and thus at high risk of Clostridioides difficile infections (CDI). As bacterial infections are a common cause for treatment-related mortality in these patients, we conducted a retrospective study to analyze the incidence of CDI and to evaluate risk factors for CDI in a large uniformly treated AML cohort. A total of 415 AML patients undergoing intensive induction chemotherapy between 2007 and 2019 were included in this retrospective analysis. Patients presenting with diarrhea and positive stool testing for toxin-producing Clostridioides difficile were defined to have CDI. CDI was diagnosed in 37 (8.9%) of 415 AML patients with decreasing CDI rates between 2013 and 2019 versus 2007 to 2012. Days with fever, exposition to carbapenems, and glycopeptides were significantly associated with CDI in AML patients. Clinical endpoints such as length of hospital stay, admission to ICU, response rates, and survival were not adversely affected. We identified febrile episodes and exposition to carbapenems and glycopeptides as risk factors for CDI in AML patients undergoing induction chemotherapy, thereby highlighting the importance of interdisciplinary antibiotic stewardship programs guiding treatment strategies in AML patients with infectious complications to carefully balance risks and benefits of anti-infective agents.
