Bectumomab (marketed under the trade name LymphoScan) is a mouse monoclonal antibody labelled with the radioactive isotope technetium-99m. It is used to detect non-Hodgkin's lymphoma. [1] [2]
Non-Hodgkin lymphoma (NHL) is a group of blood cancers that includes all types of lymphoma except Hodgkin lymphomas. Symptoms include enlarged lymph nodes, fever, night sweats, weight loss and tiredness. Other symptoms may include bone pain, chest pain or itchiness. Some forms are slow-growing, while others are fast-growing.
Lymphoma is a group of blood cancers that develop from lymphocytes. The name often refers to just the cancerous versions rather than all such tumors. Signs and symptoms may include enlarged lymph nodes, fever, drenching sweats, unintended weight loss, itching, and constantly feeling tired. The enlarged lymph nodes are usually painless. The sweats are most common at night.
Reed–Sternberg cells are distinctive, giant cells found with light microscopy in biopsies from individuals with Hodgkin lymphoma. They are usually derived from B lymphocytes, classically considered crippled germinal center B cells, meaning they have not undergone hypermutation to express their antibody. Seen against a sea of B cells, they give the tissue a moth-eaten appearance.
Rituximab, sold under the brand name Rituxan among others, is a 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 injection into a vein.
Cutaneous T cell lymphoma (CTCL) is a class of non-Hodgkin lymphoma, which is a type of cancer of the immune system. Unlike most non-Hodgkin lymphomas, CTCL is caused by a mutation of T cells. The cancerous T cells in the body initially migrate to the skin, causing various lesions to appear. These lesions change shape as the disease progresses, typically beginning as what appears to be a rash which can be very itchy and eventually forming plaques and tumors before spreading to other parts of the body.
Ann Arbor staging is the staging system for lymphomas, both in Hodgkin's lymphoma and non-Hodgkin lymphoma. It was initially developed for Hodgkin's, but has some use in NHL. It has roughly the same function as TNM staging in solid tumors.
Ibritumomab tiuxetan, sold under the trade name Zevalin, is a monoclonal antibody radioimmunotherapy treatment for relapsed or refractory, low grade or transformed B cell non-Hodgkin's lymphoma, a lymphoproliferative disorder. 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:
B symptoms refer to systemic symptoms of fever, night sweats, and weight loss which can be associated with both Hodgkin's lymphoma and non-Hodgkin's lymphoma. The presence or absence of B symptoms has prognostic significance and is reflected in the staging of these lymphomas.
T-cell lymphomas are lymphomas that affect T cells. There are four major types, and they account for about one in ten cases of non-Hodgkin lymphoma.
The B-cell lymphomas are types of lymphoma affecting B cells. Lymphomas are "blood cancers" in the lymph nodes. They develop more frequently in older adults and in immunocompromised individuals.
Pixantrone is an experimental antineoplastic (anti-cancer) drug, an analogue of mitoxantrone with fewer toxic effects on cardiac tissue. It acts as a topoisomerase II poison and intercalating agent. The code name BBR 2778 refers to pixantrone dimaleate, the actual substance commonly used in clinical trials.
Bendamustine, sold under the brand name Treanda among others, is a chemotherapy medication used in the treatment of chronic lymphocytic leukemia (CLL), multiple myeloma, and non-Hodgkin's lymphoma. It is given by injection into a vein.
Hodgkin lymphoma (HL) is a type of lymphoma in which cancer originates from a specific type of white blood cells called lymphocytes. Symptoms may include fever, night sweats, and weight loss. Often there will be non-painful enlarged lymph nodes in the neck, under the arm, or in the groin. Those affected may feel tired or be itchy.
Brentuximab vedotin is an antibody-drug conjugate medication used to treat relapsed or refractory Hodgkin lymphoma (HL) and systemic anaplastic large cell lymphoma (ALCL). It selectively targets tumor cells expressing the CD30 antigen, a defining marker of Hodgkin lymphoma and ALCL.
Idelalisib, sold under the brand name Zydelig, is a medication used to treat certain blood cancers.
Seattle Genetics is a biotechnology company focused on developing and commercializing innovative, empowered monoclonal antibody-based therapies for the treatment of cancer. The company, headquartered in Bothell, Washington, is the industry leader in antibody-drug conjugates or ADCs, a technology designed to harness the targeting ability of monoclonal antibodies to deliver cell-killing agents directly to cancer cells. Antibody-drug Conjugates are intended to spare non-targeted cells and thus reduce many of the toxic effects of traditional chemotherapy, while potentially enhancing antitumor activity.
Copanlisib is a drug which is approved by US FDA for the treatment of adult patients experiencing relapsed follicular lymphoma who have received at least two prior systemic therapies.
Loncastuximab tesirine or ADCT-402 is an antibody-drug conjugate (ADC) composed of a humanized antibody targeting the protein CD19, which is expressed in a wide range of B cell hematological tumors. The experimental drug, developed by ADC Therapeutics is being tested in clinical trials for the treatment of B-cell non-Hodgkin lymphoma (NHL) and B-cell acute lymphoblastic leukemia (ALL).
Camidanlumab tesirine is an antibody-drug conjugate (ADC) composed of a human antibody that binds to the protein CD25, conjugated to a pyrrolobenzodiazepine dimer toxin. The experimental drug, developed by ADC Therapeutics is being tested in clinical trials for the treatment of B-cell Hodgkin's lymphoma (HL) and non-Hodgkin lymphoma (NHL), and for the treatment of B-cell acute lymphoblastic leukemia (ALL) and acute myeloid leukemia (AML).
