What is CAR-T therapy?
Chimeric antigen receptor (CAR) T-cell therapy is a way to get immune cells called T cells (a type of white blood cell) to fight cancer by changing them in the lab so they can find and destroy cancer cells. CAR T-cell therapy is also sometimes talked about as a type of cell-based gene therapy , because it involves altering the genes inside T cells to help them attack the cancer.
What is CAR T cell therapy for blood cancer?
CAR T-cell therapy is a type of immunotherapy. You might also hear it called a type of adoptive cell transfer. CAR T-cell therapy is a very complex and specialist treatment.

First, white blood cells (which include T cells) are removed from the patient’s blood using a procedure called leukapheresis. During this procedure, patients usually lie in bed or sit in a reclining chair. Two IV lines are needed because blood is removed through one line, the white blood cells are separated out, and then the blood is put back into the body through the other line. Sometimes a special type of IV line called a central venous catheter is used, which has both IV lines built in.
