光动力疗法(photodynamic Therapy简称PDT),是指利用某些可被恶性肿瘤细胞特异性摄入,或可在恶性肿瘤细胞中选择性潴留的光敏物质经一定波长光的激发后产生一系列化学变化,从而造成肿瘤细胞坏死,达到选择性的杀伤肿瘤目的,是一种肿瘤辅助性治疗方法.我院引进该项技术自1993年4月至1994年3月期间对31例肿瘤患者进行治疗,取得了一定效果和经验,现总结如下:1 材料与方法1.1 一般资料 本组31例中,男性21例,女性10例;年龄23～70岁,平均53.3岁.所有病例都经病理组织学诊断确诊.其中食道癌6例,胃癌8例,直肠癌6例,左颌下腺癌1例,舌癌1例,纤维肉瘤2
Photodynamic Therapy (PDT) refers to the use of certain photosensitive substances that can be specifically taken up by malignant cells or selectively retained in malignant cells to produce a series of chemical changes after being excited by certain wavelengths of light. , Which causes necrosis of tumor cells and achieves the purpose of selectively killing tumors. It is a tumor-assisted therapeutic method. Our hospital introduced this technique to treat 31 patients with tumors from April 1993 to March 1994. Some results and experience are summarized as follows: 1 Materials and methods 1.1 General information In this group of 31 patients, 21 were males and 10 were females; aged 23 to 70 years, mean 53.3 years old. All cases were diagnosed by histopathological diagnosis. Among them, 6 cases of esophageal cancer, 8 cases of gastric cancer, 6 cases of rectal cancer, 1 case of left submandibular gland cancer, 1 case of tongue cancer, fibrosarcoma 2
