• diagnosis
  • To make this diagnosis under its present system of classification, the WHO emphasizes the identification of "hallmark" cells and immunopositivity for CD30. (wikipedia.org)
  • Also required in the diagnosis is immunophenotypic evidence that cells are T lymphocytes, such as the expression of immunologic markers CD3 or CD4, but CD30 expression must be present in all neoplastic cells. (wikipedia.org)
  • Lymphoma : pathology, diagnosis and treatment (Second ed.). p. 1. (wikipedia.org)

  • Lymphomas and leukemias are a part of the broader group of tumors of the hematopoietic and lymphoid tissues. (wikipedia.org)
  • Thus, lymphomas and leukemias are both tumors of the hematopoietic and lymphoid tissues, and as lymphoproliferative disorders, lymphomas and lymphoid leukemias are closely related, to the point that some of them are unitary disease entities that can be called by either name (for example, adult T-cell leukemia/lymphoma). (wikipedia.org)

  • Leukemia
  • The latter phase of the disease is aggressive and typically responds relatively poorly to anti-leukemia chemotherapeutic drug regimens. (wikipedia.org)
  • Lymphocyte
  • Lymphocyte-variant hypereosinophila, also termed lymphocyte variant eosinophilia, is a rare disorder in which eosinophilia or hypereosinophilia (i.e. a large or extremely large increase in the number of eosinophils in the blood circulation) is caused by aberrant population of lymphocytes. (wikipedia.org)
  • maturation
  • These aberrant lymphocytes function abnormally by stimulating the proliferation and maturation of bone marrow eosinophil-precursor cells termed colony forming unit-Eosinophils or CFU-Eos. (wikipedia.org)
  • cancers
  • Lymphoma cancers have not been seen with MTX in IBD patients, however, many fewer children with IBD have been given MTX than the other immunomodulators so it may be too early to tell. (docplayer.net)
  • Lymphoma is a group of blood cancers that develop from lymphocytes (a type of white blood cell). (wikipedia.org)
  • The main classes are malignant neoplasms (that is, cancers) of the lymphocytes, a type of white blood cell that belongs to both the lymph and the blood and pervades both. (wikipedia.org)
  • Among the malignant brain cancers, gliomas of the brainstem and pons, glioblastoma multiforme, and high-grade (highly anaplastic) astrocytoma are among the worst. (wikipedia.org)
  • cancer
  • Officer Segur, 28, was diagnosed May 30 with anaplastic large-cell non-Hodgkins lymphoma, a particularly aggressive and rare form of cancer. (telegram.com)
  • Roundup weed killer has been linked to an increased risk for anaplastic large cell lymphoma, an aggressive cancer that occurs when white blood cells called lymphocytes grow out of control. (schmidtandclark.com)
  • Anaplastic large cell lymphoma is a cancer of the lymphatic system that occurs when white blood cells called T-cell lymphocytes divide and grow out of control. (schmidtandclark.com)
  • Lymphoma is a cancer that occurs in 1 in 100,000 people over a 10 year period. (docplayer.net)
  • Sunitinib malate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. (clinicaltrials.gov)
  • This clinical trial studies the side effects and best dose of giving fludarabine and total-body irradiation (TBI) together followed by a donor stem cell transplant and cyclosporine and mycophenolate mofetil in treating human immunodeficiency virus (HIV)-positive patients with or without cancer. (clinicaltrials.gov)
  • The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). (clinicaltrials.gov)
  • Intravacular lymphoma is an aggressive cancer that is rapidly fatal without treatment, but which can respond well to combination chemotherapy, usually some combination of Rituximab, Cyclophosphamide, Adriamycin, Oncovin, and prednisone (R-CHOP). (wikipedia.org)
  • instead, it is linked to a monoclonal antibody (MAB) which directs it to the cancer cells. (wikipedia.org)
  • Traditional chemotherapeutic agents are cytotoxic by means of interfering with cell division (mitosis) but cancer cells vary widely in their susceptibility to these agents. (wikipedia.org)
  • Lung cancer, also known as lung carcinoma, is a malignant lung tumor characterized by uncontrolled cell growth in tissues of the lung. (wikipedia.org)
  • Environmental exposure to ionizing radiation from both natural background sources and artificial sources is suspected to play a significant role, and there are significant increased rates of thyroid cancer in those exposed to mantlefield radiation for lymphoma, and those exposed to iodine-131 following the Chernobyl, Fukushima, Kyshtym, and Windscale nuclear disasters. (wikipedia.org)
  • apoptosis
  • To a large extent, chemotherapy can be thought of as a way to damage or stress cells, which may then lead to cell death if apoptosis is initiated. (wikipedia.org)
  • These changes affect the normal functions of the cell, including cell proliferation, programmed cell death (apoptosis) and DNA repair. (wikipedia.org)
  • lymphocytes
  • Because of the effect on immune cells (especially lymphocytes), chemotherapy drugs often find use in a host of diseases that result from harmful overactivity of the immune system against self (so-called autoimmunity). (wikipedia.org)
  • PTCL
  • PTCL specifically affects T-cells, and results when T-cells develop and grow abnormally. (wikipedia.org)
  • However, in recent years, scientists have developed techniques to better recognize the different types of lymphomas, such as PTCL. (wikipedia.org)
  • Currently PTCL is treated similarly to B-cell lymphomas. (wikipedia.org)

  • protein
  • Western blots were performed on whole-cell lysate, with equal protein loading in each lane, with the use of anti-STAT3 rabbit polyclonal antibody sc-482X (Santa Cruz Biotechnology, Inc. (g3journal.org)
  • These lymphomas show immunopositivity for ALK protein in 70% of cases. (wikipedia.org)
  • In some non-Hodgkin lymphomas, an increased amount of protein produced by the lymphoma cells causes the blood to become so thick that plasmapheresis is performed to remove the protein. (wikipedia.org)
  • poorly
  • Compared with the germinal center B-cell−like form, activated B-cell−like lymphomas respond much more poorly to current therapies and often exhibit overexpression or overactivation of STAT3. (g3journal.org)
  • bone
  • These are medications that reduce (suppress) the activity of the immune system by suppressing the bone marrow where immune cells are formed. (docplayer.net)
  • Many of the side effects of chemotherapy can be traced to damage to normal cells that divide rapidly and are thus sensitive to anti-mitotic drugs: cells in the bone marrow, digestive tract and hair follicles. (wikipedia.org)
  • clinical
  • In many clinical settings, however, studies on the T cell receptor and IL-5 are not available and therefore not routine parts of the diagnostic work-up or criteria for the disease. (wikipedia.org)
