Effectiveness of community-based hypertension management on hypertension in the urban slums of Haiti: A mixed methods study.

Hypertension is a leading contributor to mortality in low-middle income countries including Haiti, yet only 13% achieve blood pressure (BP) control. We evaluated the effectiveness of a community-based hypertension management program delivered by community health workers (CHWs) and physicians among 100 adults with uncontrolled hypertension from the Haiti Cardiovascular Disease Cohort. The 12-month intervention included: community follow-up visits with CHWs (1 month if BP uncontrolled ≥140/90, 3 months otherwise) for BP measurement, lifestyle counseling, medication delivery, and dose adjustments.

Survival Improvement over Time of 960 s-AML Patients Included in 13 EORTC-GIMEMA-HOVON Trials.

We report the outcomes of secondary acute myeloid leukemia (s-AML) patients included in one of 13 European Organisation for Research and Treatment of Cancer (EORTC) collaborative AML trials using intensive remission-induction chemotherapy. Among 8858 patients treated between May 1986 and January 2008, 960 were identified as having s-AML, either after MDS (cohort A; = 508), occurring after primary solid tumors or hematologic malignancies other than MDS (cohort B; = 361), or after non-malignant conditions or with a history of toxic exposure (cohort C; = 91). Median age was 64 years, 60 years and 61 years in cohort A, B and C, respectively.

Impact of the type of anthracycline and of stem cell transplantation in younger patients with acute myeloid leukaemia: Long-term follow up of a phase III study.

We provide a long-term evaluation of patients enrolled in the EORTC/GIMEMA AML-10 trial which included a total of 2157 patients, 15-60 years old, randomized to receive either daunorubicin (DNR, 50 mg/m ), mitoxantrone (MXR, 12 mg/m ), or idarubicin (IDA, 10 mg/m ) in addition to standard-dose cytarabine and etoposide for induction chemotherapy and intermediate dose cytarabine for consolidation. Younger patients who reached complete remission with complete (CR) or incomplete (CRi) recovery were then scheduled to receive an allogeneic hematopoietic stem cell transplantation (HSCT). That was if they had a HLA-identical sibling donor; in all other cases, an autologous HSCT had to be administered.

Impact of induction regimen and allogeneic hematopoietic cell transplantation on outcome in younger adults with acute myeloid leukemia with a monosomal karyotype.

Monosomal karyotype confers a poor prognosis in patients with acute myeloid leukemia. Here, we determined the impact of the type of remission-induction chemotherapy and the impact of having a donor in younger acute myeloid leukemia patients with a monosomal karyotype included in two phase III trials. In the first trial patients were randomized to receive either daunorubicin, mitoxantrone, or idarubicin in addition to standard-dose cytarabine and etoposide for induction chemotherapy.

Cytogenetic clonal heterogeneity is not an independent prognosis factor in 15-60-year-old AML patients: results on 1291 patients included in the EORTC/GIMEMA AML-10 and AML-12 trials.

Unlabelled: The presence of cytogenetic clonal heterogeneity has been associated with poor prognosis in patients with acute myeloid leukemia (AML). Here, we reassessed this association. The study cohort consisted of all patients with an abnormal karyotype randomized in the EORTC/GIMEMA AML-10 and AML-12 trials.

Phase 2b study of 2 dosing regimens of quizartinib monotherapy in -ITD-mutated, relapsed or refractory AML.

This randomized, open-label, phase 2b study (NCT01565668) evaluated the efficacy and safety of 2 dosing regimens of quizartinib monotherapy in patients with relapsed/refractory (R/R) -internal tandem duplication (ITD)-mutated acute myeloid leukemia (AML) who previously underwent transplant or 1 second-line salvage therapy. Patients (N = 76) were randomly assigned to 30- or 60-mg/day doses (escalations to 60 or 90 mg/day, respectively, permitted for lack/loss of response) of single-agent oral quizartinib dihydrochloride. Allelic frequency of at least 10% was defined as -ITD-mutated disease.

Endothelial protein C receptor gene 6936A/G single-nucleotide polymorphism as a possible biomarker of thrombotic risk in acute myeloid leukemia.

Protein C (PC) is a natural anticoagulant, which interacts with the endothelial PC receptor (EPCR). EPCR single-nucleotide polymorphism (SNP) 6936A/G results in high levels of a free soluble form of EPCR (sEPCR) and may affect the risk of coagulation. The objective of this study was to assess whether the 6936A/G SNP of the EPCR gene is involved in the procoagulant activity displayed by hematological malignancies.

Decitabine improves progression-free survival in older high-risk MDS patients with multiple autosomal monosomies: results of a subgroup analysis of the randomized phase III study 06011 of the EORTC Leukemia Cooperative Group and German MDS Study Group.

In a study of elderly AML patients treated with the hypomethylating agent decitabine (DAC), we noted a surprisingly favorable outcome in the (usually very unfavorable) subgroup with two or more autosomal monosomies (MK2+) within a complex karyotype (Lübbert et al., Haematologica 97:393-401, 2012). We now analyzed 206 myelodysplastic syndrome (MDS) patients (88 % of 233 patients randomized in the EORTC/GMDSSG phase III trial 06011, 61 of them with RAEBt, i.

Prognosis of body mass index and chemotherapy dose capping in acute myeloid leukaemia.

Body Mass Index (BMI) prognosis in acute myeloid leukaemia (AML) is unknown. Capping chemotherapy dose at 2m(2) of body surface area (BSA) is used without any rationale. We assessed whether both of them could be correlated with outcome in 233 AML patients.

Specific scoring systems to predict survival of patients with high-risk myelodysplastic syndrome (MDS) and de novo acute myeloid leukemia (AML) after intensive antileukemic treatment based on results of the EORTC-GIMEMA AML-10 and intergroup CRIANT studies.

High-risk myelodysplastic syndrome (MDS) patients have usually a less favorable outcome after intensive treatment compared with de novo acute myeloid leukemia (AML) patients. This may reflect different disease-related and patient-related factors. The purpose of this analysis is to identify disease-specific prognostic factors and to develop prognostic scores for both patient groups.

A subset of bone marrow stromal cells regulate ATP-binding cassette gene expression via insulin-like growth factor-I in a leukemia cell line.

The importance of the insulin-like growth factor, IGF, as a signaling axis in cancer development, progression and metastasis is highlighted by its effects on cancer cells, notably proliferation and acquired resistance. The role of the microenvironment within which cancer cells evolve and which mediates this effect is far from clear. Here, the involvement of IGF-I in inducing multidrug resistance in a myeloid leukemia cell line, grown in the presence of bone marrow-derived stromal cells called 'Hospicells' (BMH), is demonstrated.

Clinical and biological impact of TET2 mutations and expression in younger adult AML patients treated within the EORTC/GIMEMA AML-12 clinical trial.

We assessed the prognostic impact of TET2 mutations and mRNA expression in a prospective cohort of 357 adult AML patients < 60 years of age enrolled in the European Organization For Research and Treatment of Cancer (EORTC)/Gruppo Italiano Malattie Ematologiche dell' Adulto (GIMEMA) AML-12 06991 clinical trial. In addition the co-occurrence with other genetic defects and the functional consequences of TET2 mutations were investigated. TET2 mutations occurred in 7.

Characterization of acute myeloid leukemia based on levels of global hydroxymethylation.

Patients with acute myeloid leukemia (AML) frequently harbor mutations in genes involved in the DNA (hydroxy)methylation pathway (DNMT3A, TET2, IDH1, and IDH2). In this study, we measured 5-hydroxymethylcytosine (5hmC) levels in 206 clinically and molecularly well-characterized younger adult AML patients (≤60 years) included in the European Organization for Research and Treatment of Cancer/Gruppo Italiano Malattie Ematologiche dell'Adulto (EORTC/GIMEMA) AML-12 06991 clinical trial and correlated the 5hmC levels with mutational status and overall survival (OS). In healthy control cells, 5hmC levels were confined to a narrow range (1.

Interest of cytogenetic and FISH evaluation for prognosis evaluation in 198 patients with acute myeloid leukemia in first complete remission in a single institution.

The prognostic interest of cytogenetic remission and fluorescent in situ hybridization (FISH) evaluation in patients with abnormal karyotype acute myeloid leukemia (AML) has been poorly studied. Among 198 patients that reached complete remission (CR), 24 did not reach cytogenetic remission (CyCR). CyCR had no prognosis impact, especially in patients with intermediate or unfavorable cytogenetic.

Acute myeloid leukemia in patients older than 75: prognostic impact of FLT3-ITD and NPM1 mutations.

The benefit associated with chemotherapy in older patients with acute myeloid leukemia (AML) is debated. The prognostic impact of molecular mutations in these patients is unknown. We identified 79 patients with AML aged 75 years or over.

High-dose cytarabine in induction treatment improves the outcome of adult patients younger than age 46 years with acute myeloid leukemia: results of the EORTC-GIMEMA AML-12 trial.

Purpose: Cytarabine plays a pivotal role in the treatment of patients with acute myeloid leukemia (AML). Most centers use 7 to 10 days of cytarabine at a daily dose of 100 to 200 mg/m(2) for remission induction. Consensus has not been reached on the benefit of higher dosages of cytarabine.

Sequential combination of gemtuzumab ozogamicin and standard chemotherapy in older patients with newly diagnosed acute myeloid leukemia: results of a randomized phase III trial by the EORTC and GIMEMA consortium (AML-17).

Purpose: This randomized trial evaluated the efficacy and toxicity of sequential gemtuzumab ozogamicin (GO) and standard chemotherapy in older patients with newly diagnosed acute myeloid leukemia (AML).

Patients And Methods: Patients (n = 472) age 61 to 75 years were randomly assigned to induction chemotherapy with mitoxantrone, cytarabine, and etoposide preceded, or not, by a course of GO (6 mg/m(2) on days 1 and 15). In remission, patients received two consolidation courses with or without GO (3 mg/m(2) on day 0).

Applying ecological and evolutionary theory to cancer: a long and winding road.

Since the mid 1970s, cancer has been described as a process of Darwinian evolution, with somatic cellular selection and evolution being the fundamental processes leading to malignancy and its many manifestations (neoangiogenesis, evasion of the immune system, metastasis, and resistance to therapies). Historically, little attention has been placed on applications of evolutionary biology to understanding and controlling neoplastic progression and to prevent therapeutic failures. This is now beginning to change, and there is a growing international interest in the interface between cancer and evolutionary biology.

Soluble endothelial protein C receptor (sEPCR) is likely a biomarker of cancer-associated hypercoagulability in human hematologic malignancies.

Elevated plasma level of soluble endothelial protein C receptor (sEPCR) may be an indicator of thrombotic risk. The present study aims to correlate leukemia-associated hypercoagulability to high level plasma sEPCR and proposes its measurement in routine clinical practice. EPCR expressions in leukemic cell lines were determined by flow cytometry, immunocytochemistry, and reverse transcription polymerase chain reaction (RT-PCR).

Intensive consolidation therapy compared with standard consolidation and maintenance therapy for adults with acute myeloid leukaemia aged between 46 and 60 years: final results of the randomized phase III study (AML 8B) of the European Organization for Research and Treatment of Cancer (EORTC) and the Gruppo Italiano Malattie Ematologiche Maligne dell'Adulto (GIMEMA) Leukemia Cooperative Groups.

The most effective post-remission treatment to maintain complete remission (CR) in adults aged between 46 and 60 years with acute myeloid leukaemia (AML) is uncertain. Previously untreated patients with AML in CR after induction chemotherapy with daunorubicin and cytarabine were randomized between two intensive courses of consolidation therapy containing high-dose cytarabine, combined with amsacrine or daunorubicin and a standard consolidation and maintenance therapy containing standard dose cytarabine and daunorubicin. One hundred fifty-eight CR patients were assigned to the intensive group and 157 patients to the standard group.

Double-delayed intensification paediatric protocol without radiotherapy is an efficient treatment in adult lymphoblastic lymphoma.

Lymphoblastic lymphoma (LBL) is a rare disease associated with favourable prognosis in childhood but with poor prognosis in adults when treated with conventional non-Hodgkin lymphoma regimens. Improvements in long-term outcome have been made since the use of acute lymphoblastic leukaemia (ALL) regimens. We report here the feasibility of a double-delayed intensification paediatric protocol in 12 adult LBL patients.
