BACKGROUND: Some patients with chronic myeloid leukemia (CML) have a history of previous malignancies. To the authors' knowledge, outcomes for CML diagnosed in these patients have not been well described. The current study was conducted to determine the outcome of patients with CML and a history of prior malignancies. METHODS: The current study included patients who were enrolled in clinical trials of tyrosine kinase inhibitors as initial therapy for CML in chronic phase from July 2000 to January 2014...

Myelodysplastic syndromes (MDS) are a group of hematopoietic disorders affecting the myeloid lineage, characterized by cytopenias and clonal evolution to acute myeloid leukemia (AML). We hypothesized that natural killer (NK) cells and their activating killer immunoglobulin-like receptors (aKIRs) influence the immune surveillance and clinical outcome of patients with MDS. Here, we first examined the distribution of aKIR genes and haplotype in two independent cohorts of MDS and AML patients. The median number of aKIR genes was lower in MDS patients than healthy controls (2 vs...

BACKGROUND: The outcome of patients with higher risk myelodysplastic syndromes (MDS) after hypomethylating agent (HMA) failure is poor. This study evaluated the safety and activity of a combination of low-dose clofarabine and cytarabine for these patients. METHODS: Seventy patients with higher risk MDS who had no response, progressed, or relapsed after at least 4 cycles of HMA therapy were treated. RESULTS: The median age was 72 years. Thirty-nine percent of the patients had high-risk disease according to the International Prognostic Scoring System, and 50% of the patients had poor-risk cytogenetics...

BACKGROUND: The introduction of novel prognostic factors such as minimal residual disease (MRD) and genomic profiling has led to the reevaluation of the role of cytogenetics and other conventional factors in risk stratification for acute lymphoblastic leukemia (ALL). METHODS: This study assessed the impact of baseline cytogenetics on the outcomes of 428 adult patients with Philadelphia chromosome-negative ALL who were receiving frontline chemotherapy. Three hundred thirty patients (77%) were treated with hyperfractionated cyclophosphamide, vincristine, doxorubicin, and dexamethasone-based regimens, and 98 (23%) were treated with the augmented Berlin-Frankfurt-Munster regimen...

Phosphatidylinositol-3-kinase (PI3K) signaling plays a crucial role in oncogene-mediated tumor growth and proliferation. Buparlisib (BKM120) is an oral pan-class I PI3K inhibitor. This phase I study was conducted to determine the dose limiting toxicity (DLT) and maximum tolerated dose (MTD) of BKM120 in patients (pts) with relapsed/refractory acute leukemias. Fourteen pts (12 acute myeloid leukemia, 1 acute lymphoblastic leukemia, 1 mixed phenotype leukemia) were enrolled. Twelve pts received BKM-120 80 mg/day and two 100 mg/day...

BACKGROUND: Minimal residual disease (MRD) assessment predicts survival for patients with newly diagnosed acute lymphoblastic leukemia (ALL). Its significance in relapsed/refractory ALL is less clear. METHODS: This study identified 78 patients with relapsed/refractory B-cell ALL who achieved a morphologic response with inotuzumab ozogamicin (n = 41), blinatumomab (n = 11), or mini-hyperfractionated cyclophosphamide, vincristine, and doxorubicin plus inotuzumab (n = 26) during either salvage 1 (S1; n = 46) or salvage 2 (S2; n = 32) and had undergone an MRD assessment by multiparameter flow cytometry at the time of remission...

BACKGROUND: Myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML) are myeloid neoplasms in which outgrowth of neoplastic clones disrupts normal hematopoiesis. Some patients with unexplained persistent cytopenias may not meet minimal diagnostic criteria for MDS but an alternate diagnosis is not apparent; the term idiopathic cytopenia of undetermined significance (ICUS) has been used to describe this state. MDS and AML occur primarily in older patients who are often treated outside the clinical trial setting...

BACKGROUND (OR PURPOSE): Inflammation has an essential role in the pathogenesis of myelodysplastic syndromes (MDS). Its expression is controlled by phosphodiesterase 4 (PDE4). Thus, PDE4 inhibitors might be useful therapeutic targets for MDS. PATIENTS (OR MATERIALS) AND METHODS: We evaluated the expression of each isoform of PDE4 (A, B, C, and D) using transcriptomic profiling and examined the potential impact on the outcome of patients with MDS in terms of survival and response to hypomethylating agents...

BACKGROUND: Both dasatinib and nilotinib are approved frontline therapy for chronic myeloid leukemia in chronic phase (CML-CP) based on randomized trials compared with imatinib. However, no head-to-head comparison of dasatinib and nilotinib has been conducted in patients with newly diagnosed CML-CP. METHODS: The authors conducted a propensity score (PS) matched comparison of patients with CML-CP who received frontline therapy with either dasatinib (N = 102) or nilotinib (N = 104) under the respective phase 2 trials conducted in parallel...

BACKGROUND: The role of day 14 (D14) bone marrow (BM) assessment in detecting increased blasts in patients undergoing induction for acute lymphoblastic leukemia (ALL) is not well defined. METHODS: This study evaluated 389 adolescent and adult patients with previously untreated Philadelphia chromosome-negative ALL who received frontline induction chemotherapy and for whom a D14 BM assessment was performed. RESULTS: A D14 BM blast proportion < 10% (including blast-free aplastic BM) was observed in 319 patients (82%), 10% to 29% was observed in 31 patients (8%), and ≥30% was observed in 39 patients (10%)...

Ruxolitinib is the only approved therapy for myelofibrosis (MF). However, its use in patients with myeloproliferative neoplasms (MPN) not participating in clinical studies has been poorly described. We reviewed the medical records of 45 patients (35 MF, 10 others) treated with ruxolitinib at our center, off clinical study, during the year after its approval. Patients had advanced features and were refractory to multiple therapies. Ruxolitinib was effective in reducing splenomegaly (51% response rate) and constitutional symptoms (42% response rate)...

INTRODUCTION AND OBJECTIVES: Several clinical risk scores have been developed to identify patients at high risk of all-cause mortality despite implantation of an implantable cardioverter-defibrillator. We aimed to examine and compare the predictive capacity of 4 simple scoring systems (MADIT-II, FADES, PACE and SHOCKED) for predicting mortality after defibrillator implantation for primary prevention of sudden cardiac death in a Mediterranean country. METHODS: A multicenter retrospective study was performed in 15 Spanish hospitals...

BACKGROUND: The clinical efficacy of hyperfractionated cyclophosphamide, vincristine, doxorubicin, and dexamethasone (HCVAD) plus ponatinib has not been compared with that of HCVAD plus dasatinib in patients with Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ ALL) in a randomized clinical trial. METHODS: The authors analyzed 110 patients with newly diagnosed Ph+ ALL who were enrolled in 2 consecutive, prospective, phase 2 clinical trials of frontline HCVAD with either dasatinib (63 patients) or ponatinib (47 patients)...

In patients with acute myeloid leukemia (AML), rapid reduction of circulating blasts with induction chemotherapy may serve as an in vivo marker of chemosensitivity. We performed a retrospective analysis of 363 patients with untreated AML who received induction chemotherapy in order to determine the relationship between day of blast disappearance (DOBD) and complete remission (CR) rates, event-free survival (EFS), and overall survival (OS). DOBD ≤5 vs. >5 was identified as the most discriminating cutoff for OS...

BACKGROUND: Mutations in the tumor protein 53 (TP53) gene predict a poor prognosis in patients with acute myeloid leukemia (AML). METHODS: Peripheral blood or bone marrow samples from 293 patients with newly diagnosed AML were analyzed with targeted, amplicon-based, next-generation sequencing-based mutation analysis. RESULTS: TP53 mutations were identified in 53 patients (18%; 45 were missense mutations). In 13 of the 53 patients, the most common pattern of amino acid substitution was a substitution of arginine to histidine on different codons...

Lenalidomide, with or without prednisone, is an active therapy for patients with myelofibrosis (MF). We provide an update of a phase II study of lenalidomide plus prednisone in patients with MF, after median follow up of 9 years. Forty patients were enrolled in the study and all patients were evaluable for response. Response to the treatment was reevaluated using IWG response criteria published in 2013: quality of response improved over time and overall response rate was 35%. Response in splenomegaly was seen in 39% of patients and anemia response in 32%...

BACKGROUND: The refractory nature of many cancers remains the main health challenge over the past century. The epigenetic drug, decitabine (DAC), represents one of the most promising therapeutic agents in cancers particularly in acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS). However, its ambiguous anti-tumor mechanism and the unpredictable drug-resistant nature in some population compromise its application in cancer therapy. In crosstalk with DNA methylation, histone post-translational modifications (PTMs) are the key players in modulating the downstream epigenetic status of tumor suppressor genes...

PURPOSE: Histone deacetylase inhibitors (HDACi) are promising anticancer drugs. Although some HDACi have entered the clinic, the mechanism(s) underlying their tumor selectivity are poorly understood. Experimental Design/Results: Using gene expression analysis, we define a core set of 6 genes commonly regulated in acute myeloid leukemia (AML) blasts and cell lines. c-Myc, the most prominently modulated, is preferentially altered in leukemia. Upon HDACi treatment, c-Myc is acetylated at lysine 323 and its expression decreases, leading to TRAIL activation and apoptosis...
