Photodynamic Therapy in Gastroenterology

open access: yesJournal of Gastrointestinal Cancer, 2013
Photodynamic therapy (PDT) is a minimally invasive and promising new modality to combat cancer. Upon illumination and in the presence of oxygen, the tissue-localized nontoxic sensitizer generates cytotoxic reactive oxygen species, and as a result, the selective destruction of a targeted tumor may be achieved.
