Objectives: Respiratory syncytial virus (RSV) infection causes morbidity and mortality in cancer patients. However, studies describing this infection in patients with haematological malignancies are scarce. We sought to evaluate the clinical impact of RSV infection on this patient population. Methods: We reviewed the records of patients with haematological malignancies and RSV infections cared for at our institution between January 2000 and March 2013. Results: Of the 181 patients, 71 (39%) had AML, ALL or myelodysplastic syndrome, 12 (7%) had CML or CLL, 4 (2%) had Hodgkin lymphoma, 35 (19%) had non-Hodgkin lymphoma and 59 (33%) had multiple myeloma...

Although the application of combined chemotherapy has made a great progress in treatment of adult acute myeloid leukemia (AML), the overall survival rate is still not high, mainly because of high recurrence rate and drug resistance. The treatment regimen for relapsed/refractory AML is always strong. Due to the chemotherapy drugs lacking of specific identification of tumor cells, significant adverse reactions often come out and sometimes even endanger the life of patients. In order to improve the life quality and survival rate, the new treatment strategy is urgently needed...

The myelodysplastic syndromes (MDS) are a heterogeneous group of clonal myeloid disorders characterized by ineffective hematopoiesis and increased risk of transformation to acute myelogenous leukemia (AML). The treatment of MDS is highly dependent on the reliability of the prognostic evaluation model. Current clinical prognostic scoring systems are comprised of morphology, pivotal clinical trials and cytogenetic findings. However, none of the available prognostic systems incorporates disease-related molecular abnormalities, such as somatic mutations...

Acute myelogenous leukemia is a hematologic malignancy defined by the presence of myeloid blasts causing bone marrow infiltration. Evaluation and workup of acute myelogenous leukemia is based on comprehensive medical history, physical examination, laboratory evaluation, and bone marrow sampling. Magnetic resonance (MR) imaging is the study of choice in the evaluation of this disease including the initial evaluation, treatment follow-up, and complications. Herein, we report a case of relapse of the acute myelogenic leukemia in an adult patient who presented with diffuse periostitis in his lower extremities diagnosed on MR imaging and confirmed on Technetium bone scan, which also showed periostitis along the bilateral humeri...

Gallbladder (GB) empyema is an uncommon complication in acute myeloid leukaemia (AML). Non-specific signs and symptoms and rarity of disease in AML make it difficult to diagnose early. We report a case of 13-year-old boy who had AML and developed GB empyema in the neutropaenic period. The patient was managed with antibiotics, ultrasound-guided tapping and interval cholecystectomy and recovered well. GB empyema is a life-threatening complication which should be kept as a possibility while evaluating patients with neutropaenia with pain abdomen localised to right hypochondrium as early diagnosis and treatment can lead to better outcomes...

BACKGROUND: Acute Myeloid Leukemia (AML) is a Cancer of hematopoietic stem cells with a rapid progression. TIM-3 is expressed on leukemic stem cells (LSCs) in most types of AML and might have a positive effect on maintenance of malignant phenotype. MicroRNAs play important roles in either cancer progression or suppression. In this study were evaluated, the inhibitory effect of miR-498 on TIM-3 expression and its impact on proliferation and survival of HL-60 cell line. METHODS: Firstly, the probable inhibitory effect of miR-498 on TIM-3 expression was predicted...

Acute myeloid leukemia (AML) is initiated and maintained by a unique, small subset of leukemia cells known as leukemia stem cells (LSCs). Self-renewal, quiescence and chemotherapy resistance are key stemness properties of LSCs that are essential poor clinical responses to conventional therapies. Identifying LSC surface markers and targeting LSCs are important for the development of potential therapies. In this study, application of chemotherapy treatment in AML-ETO9a (AE9a) leukemia mice led to the enrichment of a chemotherapy-resistant cell population identified as Lin- c-Kit+ c-MPL+ ...

Decreasing bone marrow (BM) microvessel density and circulating angiogenic cytokine levels are promising strategies for the treatment of relapsed and resistant acute myeloid leukemia (AML). Previous studies have reported that wogonoside could inhibit the progression of AML and suppress angiogenesis in a solid tumor, but the correlation of these two effects was ignored. In this research, we determined whether wogonoside could inhibit angiogenesis in this hematologic malignancy. We found that wogonoside could inhibit tumor growth and progression, and prolong the survival of nude mice inoculated with U937/MDR...

Acute myeloid leukemia (AML) is an aggressive hematopoietic malignancy generally associated with poor prognosis. Allogeneic hematopoietic cell transplantation (alloHCT) continues to be the most potent anti-leukemia treatment for adult patients with intermediate and high-risk AML. However, disease relapse after alloHCT remains unacceptably high and is the primary cause of treatment failure and mortality following alloHCT. It is therefore that post-transplant early cellular or pharmacologic maintenance or preemptive strategies to enhance the graft-versus-leukemia effect or to eradicate persistent minimal residual disease have been of renewed interest, particularly with the availability of more sensitive technologies to measure residual AML...

BACKGROUND/AIMS: Acute myeloid leukemia (AML) remains a hematologic malignancy with poor survival and a high risk of relapse, which is mainly caused by the emergence of multidrug resistance (MDR). The identification of novel agents to improve therapeutic strategies becomes important priority for AML treatment. It has been shown that emodin has therapeutic effects on many kinds of human malignant tumors. In this study, we investigated the anti-leukemia effects of emodin alone or in combination with cytarabine (Ara-C) on multidrug-resistant AML HL-60/ADR cells and in a mouse xenograft model of human highly tumorigenic AML HL-60/H3 cells...

Despite constant progress in prognostic risk stratification, children with acute myeloid leukemia (AML) still relapse. Treatment failure and subsequent relapse have been attributed to acute myeloid leukemia-initiating cells (LSC), which harbor stem cell properties and are inherently chemoresistant. Although pediatric and adult AML represent two genetically very distinct diseases, we reasoned that common LSC gene expression programs are shared and consequently, the highly prognostic LSC17 signature score recently developed in adults may also be of clinical interest in childhood AML...

Acute myeloid leukemia (AML) patients with NPM1 mutations demonstrate a superior response to standard chemotherapy treatment. Our previous work has shown that these favorable outcomes are linked to the cytoplasmic relocalization and inactivation of FOXM1 driven by mutated NPM1. Here, we went on to confirm the important role of FOXM1 in increased chemoresistance in AML. A multiinstitution retrospective study was conducted to link FOXM1 expression to clinical outcomes in AML. We establish nuclear FOXM1 as an independent clinical predictor of chemotherapeutic resistance in intermediate-risk AML in a multivariate analysis incorporating standard clinicopathologic risk factors...

AIM: Cytarabine (Ara-C), a mainstay of acute myeloid leukemia (AML) treatment, is a prodrug requiring activation to ara-CTP for its antileukemic activity. Aim of this study was to evaluate impact of genetic variants in the key genes involved in ara-C metabolism on the leukemic cell intracellular levels of ara-CTP. METHOD:  We investigated SNPs in 14 ara-C metabolic-pathway genes, for association with intracellular ara-CTP levels, in leukemic cells obtained post-initiation of cytarabine infusion in pediatric AML patients (n = 68)...

The prognosis of elderly patients with acute myeloid leukemia (AML) is poor. Intensive chemotherapy with the combination of cytarabine and anthracyclines is typically used as the first-line treatment in the elderly with newly diagnosed AML who are able to tolerate this regimen. Unfortunately, many patients are refractory to this treatment approach. The role of hypomethylating agents in the treatment of elderly patients with refractory AML has not been clearly defined. Therefore, we conducted a focused literature review to assess the role of hypomethylating agents in elderly patients with refractory AML...
