光辐照肿瘤诊治新技术及其临床意义 血卟啉激光辐照诊治癌症是一种恶性肿瘤早期诊断和治疗的新技术。它利用血卟啉衍生物在肿瘤组织中的选择性潴留和特定电磁辐射作用下产生的特征荧光来检测肿瘤的存在,并借其在光动力学反应中的能量转递机制,在肿瘤组织内诱发一系列氧化反应,最终导致癌细胞的灭活而达到治疗。
New technologies for the diagnosis and treatment of cancers irradiated by light and its clinical significance Hematoporphyrin laser irradiation for the diagnosis and treatment of cancer is a new technique for early diagnosis and treatment of malignant tumors. It uses the selective retention of hematoporphyrin derivatives in tumor tissues and the characteristic fluorescence produced by specific electromagnetic radiation to detect the presence of tumors and to use their energy transfer mechanisms in photodynamic reactions within the tumor tissue. Induce a series of oxidation reactions, eventually leading to the inactivation of cancer cells to achieve treatment.
