It is an application of the fundamental research of cancer immunology and a growing subspeciality of oncology .
How does immunotherapy work?
Cancer immunotherapy exploits the fact that cancer cells often have tumor antigens, molecules on their surface that can be detected by the antibody proteins of the immune system, binding to them. The tumor antigens are often proteins or other macromolecules (e.g., carbohydrates ). Normal antibodies bind to external pathogens, but the modified immunotherapy antibodies bind to the tumor antigens marking and identifying the cancer cells for the immune system to inhibit or kill. Clinical success of cancer immunotherapy is highly variable between different forms of cancer, for instance in gastric cancer certain subtypes react well to the approach whereas immunotherapy in not effective for other subtypes.
What is passive immunotherapy?
Examples include cancer vaccines and CAR-T cell, and targeted antibody therapies. In contrast, passive immunotherapy does not directly target tumor cells, but enhances the ability of the immune system to attack cancer cells. Examples include checkpoint inhibitors and cytokines .
How do cellular therapies destroy cancer cells?
Active cellular therapies aim to destroy cancer cells by recognition of distinct markers known as antigens. In cancer vaccines, the goal is to generate an immune response to these antigens through a vaccine. Currently, only one vaccine ( sipuleucel-T for prostate cancer) has been approved. In cell-mediated therapies like CAR-T cell therapy, immune cells are extracted from the patient, genetically engineered to recognize tumor specific antigens, and returned to the patient. Cell types that can be used in this way are natural killer (NK) cells, lymphokine-activated killer cells, cytotoxic T cells and dendritic cells. Finally, specific antibodies can be developed that recognize cancer cells and target them for destruction by the immune system. Examples of such antibodies include rituximab (targeting CD-20), trastuzumab (targeting HER-2), and cetuximab (targeting EGFR).
How are human antibodies produced?
Human antibodies have been produced using unmodified human DNA. Antibody-dependent cell-mediated cytotoxicity. When the Fc receptors on natural killer (NK) cells interact with Fc regions of antibodies bound to cancer cells, the NK cell releases perforin and granzyme, leading to cancer cell apoptosis.
What is provenge in prostate cancer?
Sipuleucel-T (Provenge) was approved for treatment of asymptomatic or minimally symptomatic metastatic castration-resistant prostate cancer in 2010. The treatment consists of removal of antigen-presenting cells from blood by leukapheresis and growing them with the fusion protein PA2024 made from GM-CSF and prostate-specific prostatic acid phosphatase (PAP) and reinfused. This process is repeated three times.

Why do immunotherapies not fit into a group?
This is because some drugs or treatments work in more than one way and belong to more than one group. So you might hear the same drug or treatment called different things.
Examples of activation immunotherapies
Cancer immunotherapy attempts to stimulate the immune system to reject and destroy tumors. BCG immunotherapy for early stage (non-invasive) bladder cancer utilizes instillation of attenuated live bacteria into the bladder, and is effective in preventing recurrence in up to two thirds of cases.

Categories
Immunotherapies can be categorized as active or passive. Active immunotherapy specifically targets tumor cells via the immune system. Examples include therapeutic cancer vaccines (also known as treatment vaccines, which are designed to boost the body's immune system to fight cancer), CAR-T cell, and targeted antibody therapies. In contrast, passive immunotherapy does not directly target tumor cells, but enhances the ability of the immune system to attack cancer cells…
Cellular immunotherapy
Dendritic cell therapy provokes anti-tumor responses by causing dendritic cells to present tumor antigens to lymphocytes, which activates them, priming them to kill other cells that present the antigen. Dendritic cells are antigen presenting cells (APCs) in the mammalian immune system. In cancer treatment they aid cancer antigen targeting. The only approved cellular cancer therapy based on …
Antibody therapy
Antibodies are a key component of the adaptive immune response, playing a central role in both recognizing foreign antigens and stimulating an immune response. Antibodies are Y-shaped proteins produced by some B cells and are composed of two regions: an antigen-binding fragment (Fab), which binds to antigens, and a Fragment crystallizable (Fc) region, which interacts with so-call…
