Immunotherapy or biological therapy is the treatment of disease by activating or suppressing the immune system. Immunotherapies designed to elicit or amplify an immune response are classified as activation immunotherapies, while immunotherapies that reduce or suppress are classified as suppression immunotherapies. Immunotherapy is under preliminary research for its potential to treat various forms of cancer.
Immunosuppressive drugs, also known as immunosuppressive agents, immunosuppressants and antirejection medications, are drugs that inhibit or prevent the activity of the immune system.
Cancer immunotherapy (immuno-oncotherapy) is the stimulation of the immune system to treat cancer, improving on the immune system's natural ability to fight the disease. It is an application of the fundamental research of cancer immunology and a growing subspecialty of oncology.
Targeted therapy or molecularly targeted therapy is one of the major modalities of medical treatment (pharmacotherapy) for cancer, others being hormonal therapy and cytotoxic chemotherapy. As a form of molecular medicine, targeted therapy blocks the growth of cancer cells by interfering with specific targeted molecules needed for carcinogenesis and tumor growth, rather than by simply interfering with all rapidly dividing cells. Because most agents for targeted therapy are biopharmaceuticals, the term biologic therapy is sometimes synonymous with targeted therapy when used in the context of cancer therapy. However, the modalities can be combined; antibody-drug conjugates combine biologic and cytotoxic mechanisms into one targeted therapy.
The following are notable events in the Timeline of immunology:
Monoclonal antibodies (mAbs) have varied therapeutic uses. It is possible to create a mAb that binds specifically to almost any extracellular target, such as cell surface proteins and cytokines. They can be used to render their target ineffective, to induce a specific cell signal, to cause the immune system to attack specific cells, or to bring a drug to a specific cell type.
Vulvar cancer is a cancer of the vulva, the outer portion of the female genitals. It most commonly affects the labia majora. Less often, the labia minora, clitoris, or vaginal glands are affected. Symptoms include a lump, itchiness, changes in the skin, or bleeding from the vulva.
A paraneoplastic syndrome is a syndrome that is the consequence of a tumor in the body. It is specifically due to the production of chemical signaling molecules by tumor cells or by an immune response against the tumor. Unlike a mass effect, it is not due to the local presence of cancer cells.
B-cell prolymphocytic leukemia, referred to as B-PLL, is a rare blood cancer. It is a more aggressive, but still treatable, form of leukemia.
Oncology is a branch of medicine that deals with the study, treatment, diagnosis and prevention of cancer. A medical professional who practices oncology is an oncologist. The name's etymological origin is the Greek word ὄγκος (ónkos), meaning "tumor", "volume" or "mass". Oncology is concerned with:
Adoptive cell transfer (ACT) is the transfer of cells into a patient. The cells may have originated from the patient or from another individual. The cells are most commonly derived from the immune system with the goal of improving immune functionality and characteristics. In autologous cancer immunotherapy, T cells are extracted from the patient, genetically modified and cultured in vitro and returned to the same patient. Comparatively, allogeneic therapies involve cells isolated and expanded from a donor separate from the patient receiving the 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.
Angiokinase inhibitors are a new therapeutic target for the management of cancer. They inhibit tumour angiogenesis, one of the key processes leading to invasion and metastasis of solid tumours, by targeting receptor tyrosine kinases. Examples include nintedanib, afatinib and motesanib.
Nivolumab, sold under the brand name Opdivo, is a medication used to treat a number of types of cancer. This includes melanoma, lung cancer, malignant pleural mesothelioma, renal cell carcinoma, Hodgkin lymphoma, head and neck cancer, urothelial carcinoma, colon cancer, esophageal squamous cell carcinoma, liver cancer, gastric cancer, and esophageal or gastroesophageal junction (GEJ) cancer. It is used by slow injection into a vein.
Dr. Cora Sternberg is an American medical oncologist at Weill Cornell Medicine and NewYork-Presbyterian Hospital, serving as a member of the Genitourinary (GU) Oncology Program. Dr. Sternberg facilitates the continued growth and development of clinical and translational research programs in GU malignancies. Dr. Sternberg is an internationally respected leader in the field of medical oncology and urological malignancies and a recognized expert in the area of new drug development. She is known for her seminal contributions in bladder cancer, her strong track record of sustained genito-urinary (GU) oncology leadership and collaboration in multiple practice-changing clinical trials, including novel medicines, and her current role applying her expertise in oncology and GU cancers to precision medicine to further improve outcomes for patients. Dr. Sternberg has been decidedly influential in the development of novel hormonal therapies and checkpoint inhibitors across the landscape of GU oncology as evidenced in her curriculum vitae. She is a globally respected researcher who has lectured extensively at universities and cancer symposia worldwide (>800). As Clinical Director of the Englander Institute for Precision Medicine (EIPM), Dr. Sternberg develops strategies to incorporate genomic sequencing and precision medicine throughout the Weill Cornell Medicine and NewYork-Presbyterian healthcare network, including Lower Manhattan, Brooklyn and Queens.
Immune checkpoints are regulators of the immune system. These pathways are crucial for self-tolerance, which prevents the immune system from attacking cells indiscriminately. However, some cancers can protect themselves from attack by stimulating immune checkpoint targets.
PD-1 inhibitors and PD-L1 inhibitors are a group of checkpoint inhibitor anticancer drugs that block the activity of PD-1 and PDL1 immune checkpoint proteins present on the surface of cells. Immune checkpoint inhibitors are emerging as a front-line treatment for several types of cancer.
Checkpoint inhibitor therapy is a form of cancer immunotherapy. The therapy targets immune checkpoints, key regulators of the immune system that when stimulated can dampen the immune response to an immunologic stimulus. Some cancers can protect themselves from attack by stimulating immune checkpoint targets. Checkpoint therapy can block inhibitory checkpoints, restoring immune system function. The first anti-cancer drug targeting an immune checkpoint was ipilimumab, a CTLA4 blocker approved in the United States in 2011.
Dostarlimab, sold under the brand name Jemperli, is a monoclonal antibody used as an anti-cancer medication for the treatment of endometrial cancer. Dostarlimab is a programmed death receptor-1 (PD-1)–blocking monoclonal antibody.
Bradley J. Monk is an American gynecologic oncologist, academician and researcher. He is a Professor on the Clinical Scholar Track in the Department of Obstetrics and Gynecology at the University of Arizona College of Medicine in Phoenix, Arizona, as well as at the Creighton University School of Medicine in Omaha, Nebraska. He also serves as Director of the Division of Gynecologic Oncology at the St. Joseph's Hospital and Medical Center in Phoenix.
