ECP (Photopheresis) Immunotherapy Program

We are internationally recognized for developing an immunologic treatment for advanced cutaneous T-cell lymphomas. Called extracorporeal photo chemotherapy (ECP) or photopheresis, it is one of the safest and most effective treatments available for this type cancer.  

During ECP, the patient’s blood is treated with a photosensitizing agent and exposed to specific wavelengths of light to eliminate cancerous cells from the blood and activate the immune system’s T-cells. With immune cells primed to fight off cancer, blood is then returned to the body.

ECP is also effective for treating a number of inflammatory diseases. The procedure was first developed by Yale Medicine Dermatology's Richard Edelson, MD. He and his team are international leaders in this procedure who conduct research to further improve ECP to help treat cancer and other disorders.
