    Study of association of Epstein-Barr virus in lymphomas by Epstein-Barr virus-encoded RNA in situ hybridization: An Indian perspective from a tertiary care cancer institute.
    Indian J Pathol Microbiol 2017 Jul-Sep;60(3):341-349
    Department of Pathology, Rajiv Gandhi Cancer Institute and Research Centre, New Delhi, India.
    Background: The Epstein-Barr virus (EBV), also called human herpesvirus 4, is a virus of the herpes family. The EBV-associated lymphomas include Burkitt lymphoma, classic Hodgkin lymphoma (HL), lymphomas arising in immunocompromised individuals, peripheral T-cell lymphomas, angioimmunoblastic T-cell lymphoma, extranodal nasal-type natural killer/T-cell lymphoma, and other rare histotypes.

    Objective: The present study evaluated the role of EBV as an etiologic agent in various lymphomas and determined an Indian perspective in a tertiary care cancer center compared to that of Western literature. Read More

    A review of the biologic and clinical significance of genetic mutations in angioimmunoblastic T-cell lymphoma.
    Cancer Sci 2017 Sep 10. Epub 2017 Sep 10.
    Department of Hematology, Graduate School of Comprehensive Human Sciences, University of Tsukuba, Tsukuba, Ibaraki, Japan.
    Angioimmunoblastic T-cell lymphoma (AITL) is an age-related malignant lymphoma, characterized by immune system-dysregulated symptoms. Recent sequencing studies have clarified the recurrent mutations in ras homology family member A (RHOA) and in genes encoding epigenetic regulators, tet methyl cytosine dioxygenase 2 (TET2), DNA methyl transferase 3 alpha (DNMT3A), and isocitrate dehydrogenase 2, mitochondrial (IDH2), as well as those related to the T-cell receptor signaling pathway in AITL. In this review, we will focus on how this genetic information has changed the understanding of the developmental process of AITL and will in future lead to individualized therapies for AITL patients.

    Angioimmunoblastic T-cell lymphoma and hypereosinophilic syndrome with FIP1L1/PDGFRA fusion gene effectively treated with imatinib: A case report.
    Medicine (Baltimore) 2017 Sep;96(36):e8001
    aDivision of Gastroenterology and Hematology/Oncology, Department of Medicine bOncology Center, Asahikawa Medical University Hospital, Asahikawa, Japan.
    Rationale: Hypereosinophilic syndrome (HES) is a rare disorder characterized by hypereosinophilia and organ damage. Some cases of HES are caused by the FIP1L1/PDGFRA fusion gene and respond to imatinib. FIP1L1/PDGFRA-positive HES occasionally evolves into chronic eosinophilic leukemia or into another form of myeloproliferative neoplasm; however, the development of a malignant lymphoma is very rare.

    Activation of RHOA-VAV1 signaling in angioimmunoblastic T-cell lymphoma.
    Leukemia 2017 Aug 23. Epub 2017 Aug 23.
    Department of Hematology, Graduate School of Comprehensive Human Sciences, University of Tsukuba, Tsukuba, Japan.
    Somatic G17V RHOA mutations were found in 50-70% of angioimmunoblastic T-cell lymphoma (AITL). The mutant RHOA lacks GTP binding capacity, suggesting defects in the classical RHOA signaling. Here, we discovered the novel function of the G17V RHOA: VAV1 was identified as a G17V RHOA-specific binding partner via high-throughput screening. Read More

    Clinical Practice Recommendations on Indication and Timing of Hematopoietic Cell Transplantation in Mature T Cell and NK/T Cell Lymphomas: An International Collaborative Effort on Behalf of the Guidelines Committee of the American Society for Blood and Marrow Transplantation.
    Biol Blood Marrow Transplant 2017 Aug 7. Epub 2017 Aug 7.
    Vanderbilt University Medical Center, Nashville, Tennessee.
    Recognizing the significant biological and clinical heterogeneity of mature T cell and natural killer (NK)/T cell lymphomas, the American Society for Blood and Marrow Transplantation invited experts to develop clinical practice recommendations related to the role of autologous hematopoietic cell transplantation (auto-HCT) and allogeneic HCT (allo-HCT) for specific histological subtypes. We used the GRADE methodology to aid in moving from evidence to decision making and ultimately to generating final recommendations. Auto-HCT in front-line consolidation is recommended in peripheral T cell lymphoma not otherwise specified (PTCL-NOS), angioimmunoblastic T cell lymphoma (AITL), anaplastic large cell lymphoma-anaplastic lymphoma kinase (ALCL-ALK)-negative, NK/T cell (disseminated), enteropathy-associated T cell lymphoma (EATL), and hepatosplenic lymphomas.

    Background/objectives: Lymphocytic hidradenitis is a non-specific histopathological feature observed in many dermatoses such as lupus erythematosus, morphea or scleroderma. When it occurs it is usually accompanied by the other distinctive histological features of those conditions. Isolated lymphocytic hidradenitis is uncommon and its clinical features and associated underlying medical conditions are still undetermined. Read More

    Functional analysis of acquired CD28 mutations identified in cutaneous T cell lymphoma.
    Cell Immunol 2017 Sep 10;319:28-34. Epub 2017 Jul 10.
    Washington University School of Medicine, St Louis, MO 63110, USA. Electronic address:
    CD28 is the major costimulatory receptor on T cells regulating proliferation, survival and effector function. Acquired mutations in the extracellular domain of CD28 have been identified in patients with cutaneous T cell lymphoma, angioimmunoblastic T cell lymphoma and other T cell neoplasms, suggesting it may contribute to disease pathogenesis. We used a heterologous system in which mutant human CD28 was expressed on primary murine T cells deficient in CD28 to ascertain how specific mutations identified in a genetic screen of patients with cutaneous T cell lymphoma affected normal T cell function.

    Mutations in 5-methylcytosine oxidase TET2 and RhoA cooperatively disrupt T cell homeostasis.
    J Clin Invest 2017 Aug 10;127(8):2998-3012. Epub 2017 Jul 10.
    Center for Epigenetics and Disease Prevention, Institute of Biosciences and Technology and.
    Angioimmunoblastic T cell lymphoma (AITL) represents a distinct, aggressive form of peripheral T cell lymphoma with a dismal prognosis. Recent exome sequencing in patients with AITL has revealed the frequent coexistence of somatic mutations in the Rho GTPase RhoA (RhoAG17V) and loss-of-function mutations in the 5-methylcytosine oxidase TET2. Here, we have demonstrated that TET2 loss and RhoAG17V expression in mature murine T cells cooperatively cause abnormal CD4+ T cell proliferation and differentiation by perturbing FoxO1 gene expression, phosphorylation, and subcellular localization, an abnormality that is also detected in human primary AITL tumor samples.

    Detection of the circulating tumor DNAs in angioimmunoblastic T- cell lymphoma.
    Ann Hematol 2017 Sep 20;96(9):1471-1475. Epub 2017 Jun 20.
    Department of Hematology, Faculty of Medicine, University of Tsukuba, 1-1-1 Tennodai, Tsukuba, Ibaraki, 305-8575, Japan.
    Recent genetic studies identified that the disease-specific G17V RHOA mutation, together with mutations in TET2, DNMT3A, and IDH2, is a hallmark of angioimmunoblastic T cell lymphomas (AITL). The diagnostic value of these mutations is now being investigated. Circulating tumor DNAs (ctDNAs) may offer a non-invasive testing for diagnosis and disease monitoring of cancers. Read More

    Using Murine Models to Investigate Tumor-Lymphoid Interactions: Spotlight on Chronic Lymphocytic Leukemia and Angioimmunoblastic T-Cell Lymphoma.
    Front Oncol 2017 2;7:86. Epub 2017 May 2.
    Department of Biology, University of Nebraska at Omaha, Omaha, NE, USA.
    The role of the tumor microenvironment in leukemias and lymphomas is well established, yet the intricacies of how the malignant cells regulate and influence their non-malignant counterparts remain elusive. For example, chronic lymphocytic leukemia (CLL) is an expansion of malignant CD5(+)CD19(+) B cells, yet the non-malignant T cells play just as large of a role in disease presentation and etiology. Herein, we review the dynamic tumor cell to lymphoid repertoire interactions found in two non-Hodgkin's lymphoma subtypes: CLL and angioimmunoblastic T-cell lymphoma. Read More

    Peripheral T-cell lymphomas represent 10% to 15% of non-Hodgkin lymphomas and comprise more than 20 different entities. Treatment of very rare T-cell lymphomas can be challenging because there are no large or randomized studies to guide clinical decision making, and treatment paradigms are often based on small series or imperfect data. Although a strict algorithm cannot be written with certainty, through the literature that exists and clinical experience, themes and principles of approaches do emerge that when coupled with clinical judgment allow reasonable and logical decisions.

    TET2 mutations in B cells of patients affected by angioimmunoblastic T-cell lymphoma.
    J Pathol 2017 Jun 3;242(2):129-133. Epub 2017 May 3.
    Institute of Cell Biology (Cancer Research), University of Duisburg-Essen, Medical School, Essen, Germany.
    Angioimmunoblastic T-cell lymphomas (AITLs) frequently carry mutations in the TET2 and IDH2 genes. TET2 mutations represent early genetic lesions as they had already been detected in haematopoietic precursor cells of AITL patients. We show by analysis of whole-tissue sections and microdissected PD1(+) cells that the frequency of TET2-mutated AITL is presumably even higher than reported (12/13 cases in our collection; 92%).

    The presence of Hodgkin and Reed-Sternberg (HRS)-like B-cells in peripheral T-cell lymphoma (PTCL) is rare and its clinicopathological features still remain unclear. Here, we describe 30 cases of PTCL with HRS-like B-cells from Japan. Twenty-three cases (77%) presented evidence of follicular T-helper phenotype (TFH) derivation: 12 were angioimmunoblastic T-cell lymphoma and 11 PTCL with TFH phenotype (PTCL-TFH). Read More


    Angioimmunoblastic T-cell lymphoma: the many-faced lymphoma.
    Blood 2017 Mar 23;129(9):1095-1102. Epub 2017 Jan 23.
    Division of Hematology/Oncology, University of Nebraska Medical Center, Omaha, NE.
    Angioimmunoblastic T-cell lymphoma (AITL) is an uncommon subtype of mature peripheral T-cell lymphoma (PTCL). The history of AITL is much longer and deeper than the literature would suggest given the many names that have preceded it. Advanced-stage disease is common with uncharacteristic laboratory and autoimmune findings that often slow or mask the diagnosis. Read More

    Langerhans cell histiocytosis associated with lymphoma: an incidental finding that is not associated with BRAF or MAP2K1 mutations.
    Mod Pathol 2017 May 13;30(5):734-744. Epub 2017 Jan 13.
    Department of Hematopathology, The University of Texas MD Anderson Cancer Center, Houston, TX, USA.
    Langerhans cell histiocytosis is characterized by a localized or systemic proliferation of Langerhans cells. BRAF mutations have been reported in 40-70% of cases and MAP2K1 mutations have been found in BRAF-negative cases, supporting that Langerhans cell histiocytosis is a true neoplasm, at least in mutated cases. In a small subset of patients, Langerhans cell histiocytosis is detected incidentally in a biopsy involved by lymphoma. Read More


    Recombinant human endostatin in combination with CHOP regimen for peripheral T cell lymphoma.
    Onco Targets Ther 2017 22;10:145-151. Epub 2016 Dec 22.
    Department of Medical Oncology, Fudan University Shanghai Cancer Center; Department of Oncology, Shanghai Medical College, Fudan University, Shanghai, People's Republic of China.
    Peripheral T cell lymphoma (PTCL) has a poor prognosis. Overexpression of vascular endothelial growth factor (VEGF) might contribute to the poor prognosis of PTCL and could be the target of novel therapy. The efficacy and safety of recombinant human endostatin (Endostar) in combination with cyclophosphamide, doxorubicin, vincristine and prednisone (ECHOP) have been explored in 15 PTCL patients.

    Survival outcome of patients with peripheral T-cell lymphoma-not otherwise specified (PTCL-NOS) and angioimmunoblastic T-cell lymphoma (AITL) who experience disease progression/relapse remains very poor. A total of 321 patients, newly diagnosed with PTCL-NOS (n = 180) or AITL (n = 141) between 1999 and 2015, were analysed. Failure-free survival (FFS) and overall survival (OS) were calculated from the time of first disease progression (FFS1, OS1), from second disease progression (FFS2, OS2) and from third progression (FFS3, OS3).
