  3. AIDS-Related Lymphoma Treatment (PDQ®): Treatment - Health Professional Information [NCI] - Cellular Classification of AIDS-Related Lymphoma

    Pathologically, AIDS-related lymphomas are comprised of a narrow spectrum of histologic types consisting almost exclusively of B-cell tumors of aggressive type. These include the following: Diffuse large B-cell lymphoma.B-cell immunoblastic lymphoma.Small noncleaved lymphoma, either Burkitt or Burkitt-like. All three pathologic types are equally distributed and represent aggressive disease.AIDS-related lymphomas, though usually of B-cell origin as demonstrated by immunoglobulin heavy-chain gene rearrangement studies, have also been shown to be oligoclonal and polyclonal as well as monoclonal in origin. Although human immunodeficiency virus (HIV) does not appear to have a direct etiologic role, HIV infection does lead to an altered immunologic milieu. HIV generally infects T lymphocytes whose loss of regulation function leads to hypergammaglobulinemia and polyclonal B-cell hyperplasia. B cells are not the targets of HIV infection. Instead, Epstein-Barr virus (EBV) is thought to be at

  4. Spirituality in Cancer Care (PDQ®): Supportive care - Health Professional Information [NCI] - Relation of Religion and Spirituality to Adjustment, Quality of Life, and Health Indices

    Religion and spirituality have been shown to be significantly associated with measures of adjustment and with the management of symptoms in cancer patients. Religious and spiritual coping have been associated with lower levels of patient discomfort as well as reduced hostility, anxiety, and social isolation in cancer patients [1,2,3,4] and in family caregivers.[5] Specific characteristics of strong religious beliefs, including hope, optimism, freedom from regret, and life satisfaction, have also been associated with improved adjustment in individuals diagnosed with cancer.[6,7]Type of religious coping may influence quality of life. In a multi-institutional cross-sectional study of 170 patients with advanced cancer, more use of positive religious coping methods (such as benevolent religious appraisals) was associated with better overall quality of life and higher scores on the existential and support domains of the McGill Quality of Life Questionnaire. In contrast, more use of

    Rationale for HCTBlood and marrow transplantation (BMT) or HCT is a procedure that involves infusion of cells (hematopoietic stem cells; also called hematopoietic progenitor cells) to reconstitute the hematopoietic system of a patient. The infusion of hematopoietic stem cells generally follows a preparative regimen given to the patient consisting of agents designed to do the following:Create marrow space.Suppress the patient's immune system to prevent rejection.Intensively treat malignant cells in patients with cancer.HCT is currently used in the following three clinical scenarios:Treatment of malignancies.Replacement or modulation of an absent or poorly functioning hematopoietic or immune system.Treatment of genetic diseases in which an insufficient expression of the affected gene product by the patient can be partially or completely overcome by circulating hematopoietic cells transplanted from a donor with normal gene expression.Autologous Versus Allogeneic HCTThe two major
