恶性肿瘤的血卟啉光动力学治疗或光辐射治疗或光化学治疗均为同一含义,即利用光敏剂血卟啉(简称HP)、血卟啉衍生物(简称HPD)能选择性地被恶性肿瘤所摄取,潴留于肿瘤组织内,在一定波长的光的激发下,引起一系列光化学反应,从而杀死肿瘤细胞,产生治疗作用。目前血卟啉的光动力学治疗正成为癌症治疗的一个新兴领域,引起了人们日益广泛的重视。
The hematoporphyrin photodynamic therapy or photoradiation therapy or photochemotherapy of malignant tumors all have the same meaning, namely the use of the photosensitizer hematoporphyrin (abbreviated as HP) and hematoporphyrin derivative (abbreviated as HPD) can be selectively treated by malignant tumors. Intake, retention in the tumor tissue, under the excitation of a certain wavelength of light, caused a series of photochemical reactions, thereby killing tumor cells, resulting in therapeutic effects. At present, the photodynamic therapy of hematoporphyrin is becoming an emerging field of cancer treatment, which has caused people to pay more and more attention.
