SASCRO Statement on Photodynamic Therapy

Photodynamic Therapy (PDT) refers to the administration to patients, of a drug (called a photosensitiser). The drug may be given orally or intravenously. When the patient is then exposed to light of a specific wavelength, free radicals are formed that damage cells containing the drug. The light sources are either applied directly, or via endoscopic or interstitial implants.
