Survivorship considerations after CAR T-cell therapy. CAR T cell therapy: A game changer in cancer treatment. You can learn more about how we ensure our content is accurate and current by reading our editorial policy.

Healthcare professionals may recommend chemotherapy first to prepare the immune system for the new CAR T cells. The next stage will be to insert the new CAR T cells into the person’s bloodstream through another IV line. This part of the process can take a few weeks. The scientists will wait for the cells to multiply enough to fight cancerous cells before returning them. Scientists will then add CARs to the cells, creating CAR T cells. Healthcare professionals will separate the T cells from the rest of the white cells and send them to a laboratory. The machine will then send the rest of the blood back through another IV line. This can take 2–3 hours.īlood will flow from the person’s body into a machine that will remove the white blood cells. Healthcare professionals will collect the T cells through an intravenous (IV) line. Scientists are currently investigating the use of CAR T cell therapy in many types of cancer, including:Īccording to the American Cancer Society, receiving CAR T cell therapy can take a few weeks. National Library of Medicine list over 600 ongoing CAR T cell therapy clinical trials. Yescarta is for adults with certain forms of reoccurring B cell lymphoma.Kymriah is for people under 25 years of age with leukemia and adults with reoccurring large B cell lymphoma.Tecartus is for adults with reoccurring mantle cell lymphoma.Breyanzi is for adults with some types of reoccurring B cell lymphoma.Healthcare professionals can only use them to treat specific blood cancers in certain groups of people, as follows:
The FDA have approved four CAR T cell therapies in the United States. Healthcare professionals may use CAR T cell therapy if traditional cancer treatments, such as chemotherapy, are ineffective or if the cancer returns. Which types of cancer can CAR T cell therapy treat? So, there is still much to learn about how well it works.
The Food and Drug Administration (FDA) approved the first CAR T cell therapy in 2017. However, the treatment is still very new. One 2017 review suggests that up to 90% of people with a specific form of leukemia fully recovered following this form of treatment.

Success rates vary depending on the type of cancer a healthcare professional is using CAR T cell therapy to treat. These new receptors help the T cells bind and destroy cancerous cells.ĭifferent cancers have different antigens, and scientists must adapt the treatment accordingly. Scientists add CARs to a person’s T cells. However, T cells rarely have the right receptor to bind to them.ĬAR T cell therapy is a way of training the immune system to recognize cancerous cells. T cells bind to antigens that fit their receptor, destroying the foreign substance.Ĭancerous cells also have antigens. Each foreign substance and T cell has a differently shaped antigen or receptor. Immune cell receptors and antigens fit together like a lock and key. These foreign substances also have proteins on their surfaces. T cells move around the blood, checking for foreign substances, such as viruses or bacteria. They are a type of white blood cell with proteins on the surface that act as receptors.
