The Role of Macrophage/B-Cell Interactions in the Pathophysiology of B-Cell Lymphomas.

Front Oncol 2018 8;8:147. Epub 2018 May 8.

Department of Hematopathology, The University of Texas MD Anderson Cancer Center, Houston, TX, United States.

Macrophages (MPs) are heterogeneous, multifunctional, myeloid-derived leukocytes that are part of the innate immune system, playing wide-ranging critical roles in basic biological activities, including maintenance of tissue homeostasis involving clearance of microbial pathogens. Tumor-associated MPs (TAMs) are MPs with defined specific M2 phenotypes now known to play central roles in the pathophysiology of a wide spectrum of malignant neoplasms. Also, TAMs are often intrinsic cellular components of the essential tumor microenvironment (TME). Read More

Replication and validation of genetic polymorphisms associated with survival after allogeneic blood or marrow transplant.

Blood 2017 09 15;130(13):1585-1596. Epub 2017 Aug 15.

College of Pharmacy, The Ohio State University, Columbus, OH.

Multiple candidate gene-association studies of non-HLA single-nucleotide polymorphisms (SNPs) and outcomes after blood or marrow transplant (BMT) have been conducted. We identified 70 publications reporting 45 SNPs in 36 genes significantly associated with disease-related mortality, progression-free survival, transplant-related mortality, and/or overall survival after BMT. Replication and validation of these SNP associations were performed using DISCOVeRY-BMT (Determining the Influence of Susceptibility COnveying Variants Related to one-Year mortality after BMT), a well-powered genome-wide association study consisting of 2 cohorts, totaling 2888 BMT recipients with acute myeloid leukemia, acute lymphoblastic leukemia, or myelodysplastic syndrome, and their HLA-matched unrelated donors, reported to the Center for International Blood and Marrow Transplant Research.

Network-based expression analysis reveals key genes related to glucocorticoid resistance in infant acute lymphoblastic leukemia.

Cell Oncol (Dordr) 2017 Feb 31;40(1):33-45. Epub 2016 Oct 31.

Laboratory of Systems Biology and Bioinformatics (LBB), Institute of Biochemistry and Biophysics, University of Tehran, Tehran, Iran.

Purpose: Despite vast improvements that have been made in the treatment of children with acute lymphoblastic leukemia (ALL), the majority of infant ALL patients (~80 %, < 1 year of age) that carry a chromosomal translocation involving the mixed lineage leukemia (MLL) gene shows a poor response to chemotherapeutic drugs, especially glucocorticoids (GCs), which are essential components of all current treatment regimens. Although addressed in several studies, the mechanism(s) underlying this phenomenon have remained largely unknown. A major drawback of most previous studies is their primary focus on individual genes, thereby neglecting the putative significance of inter-gene correlations. Read More

The molecular signature of AML mesenchymal stromal cells reveals candidate genes related to the leukemogenic process.

Cancer Lett 2015 Dec 13;369(1):134-43. Epub 2015 Aug 13.

Stem Cell Laboratory, Bone Marrow Transplantation Unit, National Cancer Institute (INCA), Rio de Janeiro, RJ, Brazil; Instituto Nacional de Ciência e Tecnologia Para o Controle do Câncer (INCT), Rio de Janeiro, RJ, Brazil.

Acute myeloid leukemia (AML) is a heterogeneous disease characterized by myeloid precursor proliferation in the bone marrow, apoptosis reduction and differentiation arrest. Although there are several studies in this field, events related to disease initiation and progression remain unknown. The malignant transformation of hematopoietic stem cells (HSC) is thought to generate leukemic stem cells, and this transformation could be related to changes in mesenchymal stromal cell (hMSC) signaling.

Statins and cancer.

Anticancer Agents Med Chem 2014 Jun;14(5):706-12

5 Pyramidon str 190 05, Municipality of Marathon, Athens, Greece.

Statins have pleiotropic properties and might exert an effect even in the field of cancer. Statins competitively inhibit 3-hydroxy-3-methylglutaryl coenzyme (HMG-CoA) reductase, the major rate-limiting enzyme that controls the conversion of HMG-CoA to mevalonic acid. Specifically, inhibition of HMG-CoA reductase by statins has been proved to prevent the synthesis of mevalonic acid, a precursor of non-steroidal isoprenoids, which are lipid attachment molecules for small G proteins, such as Ras, Rho and Rac.

Cryptic FUS-ERG fusion identified by RNA-sequencing in childhood acute myeloid leukemia.

Oncol Rep 2013 Dec 25;30(6):2587-92. Epub 2013 Sep 25.

Section for Cancer Cytogenetics, Institute for Medical Informatics, The Norwegian Radium Hospital, Oslo University Hospital, Oslo, Norway.

Sequential combination of cytogenetics and RNA-sequencing (RNA-Seq) has been shown to be an efficient approach to detect pathogenetically important fusion genes in neoplasms carrying only one or a few chromosomal rearrangements. We performed RNA-Seq on an acute myeloid leukemia in a 2-year-old girl with the karyotype 46,XX,add(1)(p36), der(2)t(2;3)(q21;q21),del(3)(q21),der(10)t(1;10)(q32;q24),der(16)(2qter-->2q21::16p11-->16q24::16p11-->16pter)[13]/46,XX[2] and identified a cryptic FUS/ERG fusion gene. PCR and direct sequencing verified the presence of the FUS-ERG chimeric transcript in which exon 7 of FUS from 16p11 (nt 904 in sequence with accession number NM_004960 version 3) was fused in frame to exon 8 of ERG from sub-band 21q22.

Testicular myeloid sarcoma: case report.

Rev Bras Hematol Hemoter 2013 ;35(1):68-70

Hospital Dr. Amaral Carvalho, Jaú, SP, Brazil.

Myeloid sarcomas are extramedullary solid tumors composed of immature granulocytic precursor cells. In association with acute myeloid leukemia and other myeloproliferative disorders, they may arise concurrently with compromised bone marrow related to acute myeloid leukemia, as a relapsed presentation, or occur as the first manifestation. The testicles are considered to be an uncommon site for myeloid sarcomas. Read More

Distinct clinical features of infectious complications in adult T cell leukemia/lymphoma patients after allogeneic hematopoietic stem cell transplantation: a retrospective analysis in the Nagasaki transplant group.

Biol Blood Marrow Transplant 2013 Apr 17;19(4):607-15. Epub 2013 Jan 17.

Department of Hematology, Sasebo City General Hospital, Sasebo, Japan.

Although allogeneic hematopoietic stem cell transplantation (allo-SCT) is performed as a curative option in adult T cell leukemia-lymphoma (ATL) patients, its high transplantation-related mortality raises a serious issue. The clinical features of infectious complications after transplantation are not well known. To analyze the impact of infections after allo-SCT for ATL, we retrospectively compared infectious complications in 210 patients at 3 institutions in Nagasaki prefecture between 1997 and 2009.

Therapy-related pro-B cell acute lymphoblastic leukemia: report of two patients with MLL amplification.

Cancer Genet 2012 Dec 11;205(12):653-6. Epub 2012 Dec 11.

Comprehensive Cancer Center, Department of Pathology, Wexner Medical Center at The Ohio State University, Columbus, OH, USA.

Improvements in chemotherapy and medical support of patients treated with chemotherapy and radiation have led to an ever-increasing number of cancer survivors. Unfortunately, a small fraction of these patients develop secondary hematologic malignancies as a consequence of their exposure to genotoxic anti-cancer regimens. Most of these are myeloid malignancies, therapy-related acute myeloid leukemia (t-AML) or myelodysplasia (t-MDS); however, a small but growing body of literature exists, which describes therapy-related acute lymphoblastic leukemias (t-ALL).

Mutational analysis of DNMT3A gene in acute leukemias and common solid cancers.

APMIS 2013 Feb 3;121(2):85-94. Epub 2012 Jul 3.

Department of Pathology, College of Medicine, The Catholic University of Korea, Seoul, Korea.

DNMT3A, a DNA methyltransferase that functions for de novo methylation, is important in development and many cellular processes related to tumorigenesis. Somatic mutations of DNMT3A gene, including recurrent mutations in its Arg-882, were recently reported in acute myelogenous leukemia (AML), strongly suggesting its role in development of AML. To see whether DNMT3A mutation occurs in other malignancies as well, we analyzed DNMT3A in 916 cancer tissues from 401 hematologic malignancies (AML, acute lymphoblastic leukemias (ALL), multiple myelomas and lymphomas) and 515 carcinomas (lung, breast, prostate, colorectal and gastric carcinomas) using a single-strand conformation polymorphism (SSCP) assay.

The immunophenotype of T-lymphoblastic lymphoma in children and adolescents: a Children's Oncology Group report.

Br J Haematol 2012 Nov 21;159(4):454-61. Epub 2012 Sep 21.

University of Calgary and Calgary Laboratory Services, Calgary, AB, Canada.

T-lymphoblastic leukaemia (T-ALL) and T-lymphoblastic lymphoma (T-LBL) are neoplasms derived from immature lymphoid cells of T-cell lineage. These neoplasms are biologically similar, but significant differences may exist between the two given their clinical differences. Although ample data regarding the immunophenotypic characterization T-ALL are available, there is a paucity of such data in children and adolescents with T-LBL. Read More

Acute myeloid leukemia (AML) with erythroid predominance exhibits clinical and molecular characteristics that differ from other types of AML.

PLoS One 2012 23;7(7):e41485. Epub 2012 Jul 23.

Department of Hematopathology, The University of Texas M. D. Anderson Cancer Center, Houston, Texas, United States of America.

The clinical importance of erythroid predominance in bone marrow of patients with acute myeloid leukemia (AML) is controversial. These cases represent a heterogeneous group of diseases that historically have been classified into different categories. We studied 313 AML patients and specifically compared the clinical, cytogenetic, and molecular features of cases of AML with erythroid predominance, arbitrarily defined as ≥50% erythroid precursors, to AML cases without erythroid predominance.

Infections from CVC in the pediatric neoplastic patient. Single institution experience.

Minerva Pediatr 2012 Aug;64(4):385-94

Service of Pediatric Oncology, Department of Pediatrics, Second University of the Studies in Naples, Naples, Italy.

Aim: The present clinical study was carried out in order to evaluate in a perspective way the incidence of the infections caused by CVC, the micro-organisms mostly involved in the infectious process, the condition of aplasia in patients when blood cultures show positiveness and the incidence of removals expressed as number of performed removals/number of positive blood culture.

Methods: Between January 2003 and December 2009 452 blood cultures from CVC were carried out on 120 patients affected by acute lymphoblastyic and myelougenous leukemia (38), Hodgkin and non-Hodgkin lymphoma (17) and solid tumors (65), with an average of 65 blood cultures per year showing an average positiveness of 21 cases/year. The blood cultures were performed, in hyperpyrexia, when there was a clinical suspicion of infection from CVC. Read More

Clinical and pathologic features of secondary acute promyelocytic leukemia.

Am J Clin Pathol 2012 Mar;137(3):395-402

Department of Pathology, The Johns Hopkins Hospital, Baltimore, MD, USA.

Acute promyelocytic leukemia (APL) is a relatively common form of acute myeloid leukemia (AML) that has an excellent prognosis. In contrast, secondary acute myeloid leukemias, including therapy-related AML and AML with myelodysplasia-related changes, have a relatively poor prognosis. We identified 9 cases of APL at our institution in which there was a history of chemotherapy, radiotherapy, chronic immunosuppression, or antecedent myelodysplastic syndrome. Read More

Targeting ion channels in leukemias: a new challenge for treatment.

Curr Med Chem 2012 ;19(5):683-96

Department of Experimental Pathology and Oncology, University of Florence, Viale G.B. Morgagni, 50, 50134 Firenze, Italy.

Leukemias, as other cancers, bear several genetic alterations of tumor-related genes, such as point mutations, translocations, epigenetic modifications, often accompanied by gene amplification or inactivation. The identification of tumor-related genes provides considerable insight into the biology of leukemias and opens the way to more specific pharmacological treatments. These genes comprise several ion channels and pumps, as the transport mechanisms associated with volume control, proliferation and apoptosis are often altered in cancers. Read More

Department of Clinical Genetics, University and Regional Laboratories, Skåne University Hospital, Lund University, Sweden.

Previous cytogenetic studies of myeloid and acute lymphoblastic leukemias in children with Down syndrome (ML-DS and DS-ALL) have revealed significant differences in abnormality patterns between such cases and acute leukemias in general. Also, certain molecular genetic aberrations characterize DS-related leukemias, such as GATA1 mutations in ML-DS and deregulation of the CRLF2 gene in DS-ALL. Whether microdeletions/microduplications also vary between DS and non-DS cases is presently unclear. Read More
