Peripheral T-cell Lymphoma Not Otherwise Specified
Peripheral T-cell lymphoma not otherwise specified (PTCL-NOS), is a subtype of peripheral T-cell lymphoma. Peripheral T-cell lymphoma (PTCL) is defined as a diverse group of aggressive lymphomas that develop from mature-stage white blood cells called T-cells and natural killer cells (NK cells) (see figure for an overview of PTCL subtypes). PTCL is a type of non-Hodgkin's lymphoma (NHL). PTCL specifically affects T-cells rather than B-cells, and results when T-cells develop and grow abnormally. About 30% of PTCL-NOS cases exhibit malignant T cells that are infected with the Epstein-Barr virus (EBV). When associated with EBV, PTCL-NOS is classified as one of the Epstein-Barr virus-associated lymphoproliferative diseases (see Epstein-Barr virus-associated lymphoproliferative diseases#Epstein-Barr virus-associated peripheral T cell lymphoma, not otherwise specified, Epstein-Barr virus-associated peripheral T cell lymphoma, not otherwise specified) but the relationship of EBV to the ...

Cerdulatinib
Cerdulatinib is a small molecule SYK/JAK kinase inhibitor in development for treatment of hematological malignancies. It has lowest nM IC50 values against TYK2, JAK1, JAK2, JAK3, FMS, and SYK. It is being developed by Portola Pharmaceuticals; in September 2018 the FDA granted orphan drug status to cerdulatinib for the treatment of peripheral T-cell lymphoma (PTCL).{{Cite web, url=http://phx.corporate-ir.net/phoenix.zhtml?c=198136&p=irol-newsArticle&ID=2368929, title=Investors - News Release - Portola Pharmaceuticals, Inc., website=phx.corporate-ir.net, language=en, date=September 25, 2018 See also * Ruxolitinib * Fostamatinib * Entospletinib Entospletinib is an experimental drug for the treatment of various types of cancer under development by Gilead Sciences.

Pralatrexate
Pralatrexate, sold under the brand name Folotyn, is a medication used for the treatment of relapsed or refractory peripheral T-cell lymphoma (PTCL). Pralatrexate was approved for medical use in the United States in September 2009, as the first treatment for Peripheral T-cell Lymphoma (PTCL), an often aggressive type of non-Hodgkins lymphoma. Medical uses Pralatrexate is indicated for the treatment of people with relapsed or refractory peripheral T-cell lymphoma (PTCL). Mechanism Pralatrexate is a dihydrofolate reductase inhibitor. Discovery Research on this class of drugs began in the 1950s at SRI International, where scientists were focused on developing new chemotherapies and antifolates that would be effective against tumor cells A neoplasm () is a type of abnormal and excessive growth of tissue. The process that occurs to form or produce a neoplasm is called neoplasia. The growth of a neoplasm is uncoordinated with that of the normal surrounding tissue, and persis ...

Stem Cell Transplant
Hematopoietic stem-cell transplantation (HSCT) is the transplantation of multipotent hematopoietic stem cells, usually derived from bone marrow, peripheral blood, or umbilical cord blood in order to replicate inside of a patient and to produce additional normal blood cells. It may be autologous (the patient's own stem cells are used), allogeneic (the stem cells come from a donor) or syngeneic (from an identical twin). It is most often performed for patients with certain cancers of the blood or bone marrow, such as multiple myeloma or leukemia. In these cases, the recipient's immune system is usually destroyed with radiation or chemotherapy before the transplantation. Infection and graft-versus-host disease are major complications of allogeneic HSCT. HSCT remains a dangerous procedure with many possible complications; it is reserved for patients with life-threatening diseases. As survival following the procedure has increased, its use has expanded beyond cancer to autoimmun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chemotherapy Regimens
A chemotherapy regimen is a regimen for chemotherapy, defining the drugs to be used, their dosage, the frequency and duration of treatments, and other considerations. In modern oncology, many regimens combine several chemotherapy drugs in combination chemotherapy. The majority of drugs used in cancer chemotherapy are cytostatic, many via cytotoxicity. A fundamental philosophy of medical oncology, including combination chemotherapy, is that different drugs work through different mechanisms, and that the results of using multiple drugs will be synergistic to some extent. Because they have different dose-limiting adverse effects, they can be given together at full doses in chemotherapy regimens. The first successful combination chemotherapy was MOPP, introduced in 1963 for lymphomas. The term " induction regimen" refers to a chemotherapy regimen used for the initial treatment of a disease. A " maintenance regimen" refers to the ongoing use of chemotherapy to reduce the chances of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anthracycline
Anthracyclines are a class of drugs used in cancer chemotherapy that are extracted from ''Streptomyces'' bacterium. These compounds are used to treat many cancers, including leukemias, lymphomas, breast, stomach, uterine, ovarian, bladder cancer, and lung cancers. The first anthracycline discovered was daunorubicin (trade name Daunomycin), which is produced naturally by ''Streptomyces peucetius'', a species of Actinomycetota. Clinically the most important anthracyclines are doxorubicin, daunorubicin, epirubicin and idarubicin. The anthracyclines are among the most effective anticancer treatments ever developed and are effective against more types of cancer than any other class of chemotherapeutic agents. Their main adverse effect is cardiotoxicity, which considerably limits their usefulness. Use of anthracyclines has also been shown to be significantly associated with cycle 1 severe or febrile neutropenia. Other adverse effects include vomiting. The drugs act mainly by interc ...

Food And Drug Administration (United States)
The United States Food and Drug Administration (FDA or US FDA) is a federal agency of the Department of Health and Human Services. The FDA is responsible for protecting and promoting public health through the control and supervision of food safety, tobacco products, caffeine products, dietary supplements, prescription and over-the-counter pharmaceutical drugs (medications), vaccines, biopharmaceuticals, blood transfusions, medical devices, electromagnetic radiation emitting devices (ERED), cosmetics, animal foods & feed and veterinary products. The FDA's primary focus is enforcement of the Federal Food, Drug, and Cosmetic Act (FD&C), but the agency also enforces other laws, notably Section 361 of the Public Health Service Act, as well as associated regulations. Much of this regulatory-enforcement work is not directly related to food or drugs, but involves such things as regulating lasers, cellular phones, and condoms, as well as control of disease in contexts varying fro ...

B-cells
B cells, also known as B lymphocytes, are a type of white blood cell of the lymphocyte subtype. They function in the humoral immunity component of the adaptive immune system. B cells produce antibody molecules which may be either secreted or inserted into the plasma membrane where they serve as a part of B-cell receptors. When a naïve or memory B cell is activated by an antigen, it proliferates and differentiates into an antibody-secreting effector cell, known as a plasmablast or plasma cell. Additionally, B cells present antigens (they are also classified as professional antigen-presenting cells (APCs)) and secrete cytokines. In mammals, B cells mature in the bone marrow, which is at the core of most bones. In birds, B cells mature in the bursa of Fabricius, a lymphoid organ where they were first discovered by Chang and Glick, which is why the 'B' stands for bursa and not bone marrow as commonly believed. B cells, unlike the other two classes of lymphocytes, T cells and n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
