内窥镜激光治疗是医学工程发展的产物,作为侵害性小的治疗方法,是今后迫切希望发展起来的一种方法,其中引人注目的方法为光动力治疗法(PDT),它是全新的诊断和治疗癌的方法.光化学在生物体中的应用历史悠久,但是1961年Lipson合成出肿瘤亲和性物质血卟啉以后,才开始PDT的研究.为了应用光化学原理的PDT和确立光动力诊断法,世界各国都在积极进行激光装置和光敏物质的开发和改进工作.本文主要介绍有关肺和食道癌的光动力治疗法的临床结果及其展望.
Endoscopic laser treatment is a product of the development of medical engineering. As a small invasive treatment method, it is a method that is eagerly hopefully developed in the future. Among the attractive methods is photodynamic therapy (PDT), which is completely new. Diagnosis and treatment of cancer. Photochemistry has a long history of use in living organisms. However, PDT research was started after Lipson synthesized the tumor affinity substance hematoporphyrin in 1961. In order to apply photochemical principles of PDT and establish photodynamic diagnosis In France, all countries in the world are actively developing and improving laser devices and light-sensitive substances. This article mainly introduces the clinical results and prospects of photodynamic therapy for lung and esophageal cancer.
