METHODS: 40 cases were classified stage IV with lumen obstruction after they failed all other treatment regimens. PDT was performed witn 630nm light delivered through cylinder diffusing tip quartz fibers passed through the biopsy channel of a flexible endoscope 48h after intravenous injection of the photosensitizer photofrin. PDT endoscopy was repeated and necrotic tissue was mechanically removed and, if necessary, that site or other new sites were treated after 48 hours. Two days after this another endoscopy was performed and the necrotic tissue was mechanically removed. Endoscopy was repeated one month after PDT and periodically thereafter as needed to re-treat symptomatic residual tumor.

40例肿瘤患者均属于IV期，所有患者都经过化疗、放疗或其他方法治疗无法解除腔道梗阻或不完全梗阻，部分完全梗阻患者结合其他治疗手段解除梗阻，光敏剂为photofrin，按2mg/kg体重静脉滴注，48小时后经内镜导入光导纤维给以630nm（DIOMED半导体激光治疗机）的激光照射，2天后经内镜清除坏死组织并对原有病灶和新发现病灶给以复照，之后根据具体情况给患者的病灶部位清除坏死组织。
