Rituximab, sold under the brand name Rituxan among others, is a monoclonal antibody medication used to treat certain autoimmune diseases and types of cancer. It is used for non-Hodgkin lymphoma, chronic lymphocytic leukemia, rheumatoid arthritis, granulomatosis with polyangiitis, idiopathic thrombocytopenic purpura, pemphigus vulgaris, myasthenia gravis and Epstein–Barr virus-positive mucocutaneous ulcers. It is given by slow intravenous infusion.
Ibritumomab tiuxetan, sold under the trade name Zevalin, is a monoclonal antibody radioimmunotherapy treatment for non-Hodgkin's lymphoma. The drug uses the monoclonal mouse IgG1 antibody ibritumomab in conjunction with the chelator tiuxetan, to which a radioactive isotope is added. Tiuxetan is a modified version of DTPA whose carbon backbone contains an isothiocyanatobenzyl and a methyl group.
CHOP is the acronym for a chemotherapy regimen used in the treatment of non-Hodgkin lymphoma. CHOP consists of:
Primary effusion lymphoma (PEL) is classified as a diffuse large B cell lymphoma. It is a rare malignancy of plasmablastic cells that occurs in individuals that are infected with the Kaposi's sarcoma-associated herpesvirus. Plasmablasts are immature plasma cells, i.e. lymphocytes of the B-cell type that have differentiated into plasmablasts but because of their malignant nature do not differentiate into mature plasma cells but rather proliferate excessively and thereby cause life-threatening disease. In PEL, the proliferating plasmablastoid cells commonly accumulate within body cavities to produce effusions, primarily in the pleural, pericardial, or peritoneal cavities, without forming a contiguous tumor mass. In rare cases of these cavitary forms of PEL, the effusions develop in joints, the epidural space surrounding the brain and spinal cord, and underneath the capsule which forms around breast implants. Less frequently, individuals present with extracavitary primary effusion lymphomas, i.e., solid tumor masses not accompanied by effusions. The extracavitary tumors may develop in lymph nodes, bone, bone marrow, the gastrointestinal tract, skin, spleen, liver, lungs, central nervous system, testes, paranasal sinuses, muscle, and, rarely, inside the vasculature and sinuses of lymph nodes. As their disease progresses, however, individuals with the classical effusion-form of PEL may develop extracavitary tumors and individuals with extracavitary PEL may develop cavitary effusions.
T-cell lymphoma is a rare form of cancerous lymphoma affecting T-cells. Lymphoma arises mainly from the uncontrolled proliferation of T-cells and can become cancerous.
Tositumomab is a murine monoclonal antibody which targets the CD20 antigen produced in mammalian cell. It was combined with iodine-131 to produce a radiopharmaceutical for unsealed source radiotherapy, Iodine-131 Tositumomab, for the treatment of non-Hodgkins lymphoma. It is classified as a IgG2a lambda antibody.
Richter's transformation (RT), also known as Richter's syndrome, is the conversion of chronic lymphocytic leukemia (CLL) or its variant, small lymphocytic lymphoma (SLL), into a new and more aggressively malignant disease. CLL is the circulation of malignant B lymphocytes with or without the infiltration of these cells into lymphatic or other tissues while SLL is the infiltration of these malignant B lymphocytes into lymphatic and/or other tissues with little or no circulation of these cells in the blood. CLL along with its SLL variant are grouped together in the term CLL/SLL.
Mantle cell lymphoma (MCL) is a type of non-Hodgkin's lymphoma, comprising about 6% of cases. It is named for the mantle zone of the lymph nodes where it develops. The term 'mantle cell lymphoma' was first adopted by Raffeld and Jaffe in 1991.
Chemoimmunotherapy is chemotherapy combined with immunotherapy. Chemotherapy uses different drugs to kill or slow the growth of cancer cells; immunotherapy uses treatments to stimulate or restore the ability of the immune system to fight cancer. A common chemoimmunotherapy regimen is CHOP combined with rituximab (CHOP-R) for B-cell non-Hodgkin lymphomas.
ICE in the context of chemotherapy is an acronym for one of the chemotherapy regimens, used in salvage treatment of relapsed or refractory non-Hodgkin's lymphoma and Hodgkin lymphoma.
Obinutuzumab, sold under the brand name Gazyva among others, is a humanized anti-CD20 monoclonal antibody used as a treatment for cancer. It was originated by GlycArt Biotechnology AG and developed by Roche.
Nodular lymphocyte predominant Hodgkin lymphoma (NLPHL) is a slow-growing CD20 positive form of Hodgkin lymphoma, a cancer of the immune system's B cells.
Gene expression profiling has revealed that diffuse large B-cell lymphoma (DLBCL) is composed of at least 3 different sub-groups, each having distinct oncogenic mechanisms that respond to therapies in different ways. Germinal Center B-Cell like (GCB) DLBCLs appear to arise from normal germinal center B cells, while Activated B-cell like (ABC) DLBCLs are thought to arise from postgerminal center B cells that are arrested during plasmacytic differentiation. The differences in gene expression between GCB DLBCL and ABC DLBCL are as vast as the differences between distinct types of leukemia, but these conditions have historically been grouped together and treated as the same disease.
ESHAP is an acronym for relatively intensive chemotherapy regimen that is used for salvage therapy in relapsed or refractory lymphomas and Hodgkin's lymphoma. In combination with monoclonal antibody Rituximab it is called R-ESHAP or ESHAP-R.
EPOCH is an intensive chemotherapy regimen intended for treatment of aggressive non-Hodgkin's lymphoma.
CEPP is a chemotherapy regimen that is intended for treatment of aggressive non-Hodgkin lymphomas. It consists of cyclophosphamide, etoposide, procarbazine, and prednisone. Unlike CHOP, this chemotherapy regimen does not contain doxorubicin or any other anthracycline. Thus, it can be used in patients with severe cardiovascular diseases and contraindications for doxorubicin-containing regimens. This regimen also does not contain vincristine and can be used in patients with neuropathy.
MINE in the context of chemotherapy is an acronym for one of the chemotherapy regimens used for treatment of relapsed or refractory aggressive non-Hodgkin's lymphoma and Hodgkin's lymphoma.
GemOx or GEMOX is an acronym for one of the chemotherapy regimens used in the treatment of relapsed or primary refractory non-Hodgkin's lymphoma and Hodgkin's lymphoma.
FM in the context of chemotherapy means a chemotherapy regimen used as first-line therapy in indolent lymphomas. In combination with rituximab it is called R-FM or RFM or FM-R or FMR.
FCM, or FMC in the context of chemotherapy is an acronym for a chemotherapy regimen that is used in the treatment of indolent B cell non-Hodgkin's lymphomas. In combination with Rituximab, this regimen is called R-FCM or R-FMC, or FCM-R, FMC-R.
