CAR T-cell therapy is changing cancer treatment. It uses the body’s immune system to fight cancer. This therapy has shown great promise in helping patients with hard-to-treat cancers.
This treatment works by making a patient’s T-cells attack cancer cells. First, T-cells are taken from the patient. Then, they are changed in a lab to target cancer. After that, these enhanced T-cells are put back into the patient to fight cancer.
Research on CAR T-cell therapy is growing. It has led to better survival rates and long-term remissions for some patients. We will look into how well this therapy works, what affects its success, and its future in cancer treatment.
Understanding CAR T-Cell Therapy
CAR T-cell therapy is a new way to fight cancer. It uses a patient’s own immune system. This method changes a patient’s T lymphocytes to attack cancer cells better.
How CAR T-Cell Therapy Works
The therapy starts with taking a patient’s T cells. This is done through a process called leukapheresis. Then, these cells are changed in a lab.
The change adds a special receptor to the T cells. This receptor helps them find and destroy cancer cells.
After the T cells are modified, they are grown in the lab. Millions of these cells are made to fight cancer. They are then given back to the patient.
These cells go after and kill cancer cells with the right antigen.
Types of CAR T-Cell Therapies
There are different CAR T-cell therapies for various cancers. Some are for blood cancers like:
| Therapy | Target | Approved for |
|---|---|---|
| Kymriah (tisagenlecleucel) | CD19 | Acute lymphoblastic leukemia, large B-cell lymphoma |
| Yescarta (axicabtagene ciloleucel) | CD19 | Large B-cell lymphoma |
| Tecartus (brexucabtagene autoleucel) | CD19 | Mantle cell lymphoma |
Researchers are also working on therapies for solid tumors. These include cancers like breast, lung, and colorectal. They aim to tackle the challenges of solid tumors.
“CAR T-cell therapy represents a significant advancement in personalized cancer treatment, giving hope to patients who have tried everything else.” – Dr. Sarah Johnson, oncologist
