What is photopheresis? Photopheresis (ECP) is a type of medical therapy that can be used in treating patients with problems associated with cutaneous (skin) T-cell lymphoma (CTCL) such as mycosis fungoides (MF) or Sezary syndrome. ECP is also used to treat conditions including graft-versus-host disease (GVHD) and organ transplant rejection. It was developed by THERAKOSÂ©, a Johnson & Johnson company. Photopheresis treatments at Stanford Medical Center are given at the Cancer Center in the Apheresis Area.
