概述
光动力疗法是一种两阶段治疗,它将光能与一种称为光敏剂的药物结合在一起。光敏剂可杀死通过光(通常来自激光器)激活的癌变和癌前细胞。
光敏剂在被光激活前是无毒的。但是光激活后,光敏剂会对靶组织产生毒性。
现在有几种光敏剂可用于治疗很多状况,包括痤疮、银屑病、年龄相关性黄斑变性和数种癌症。
除了用于治疗这些状况外,光动力疗法还可用于治疗细菌、真菌和病毒感染。研究表明,这种基于光的疗法可以触发人体的免疫反应,为您的身体提供摧毁癌细胞和癌前细胞的另一种手段。
目的
光动力疗法可用于治疗各种医学状况,包括:
- 胰腺癌。
- 胆管癌(又称为胆管细胞癌)。
- 食管癌。
- 肺癌。
- 头颈癌。
- 某些皮肤病,包括痤疮、银屑病、非黑色素瘤皮肤癌和癌前皮肤变化(称为光化性角化病)。
- 细菌、真菌和病毒感染。
