New approaches to local destruction of tumors: interstitial laserhyperthermia and photodynamic therapy,

摘要

Abstract: Lasers are well established as the treatment of choice in certain types of cancer, particularly the use of carbon dioxide laser for eradication of early tumors of the cervix and for lesions of the upper airways. More recently, the high-power Nd:YAG laser has proven itself of value for endoscopic palliation of advanced obstructing tumors of the gastrointestinal tract and major airways in patients who are unsuitable for surgery. However, current techniques are only scratching the surface of the potential applications of lasers in medical and surgical practice, and this article outlines two ways in which laser therapy for cancer may develop - low power interstitial hyperthermia and photodynamic therapy.!23
