纤维支气管镜检查是对支气管癌作早期诊断的重要方法,但尚有不足之处,例如早期病变可能缺乏特征性改变,易被漏诊。因此,曾研究各种标记肿瘤组织的方法。我们采用光敏剂血卟啉衍生物(HPD)作激光纤支镜检查,对26例支气管癌进行对照观察,报道如下。资料和方法(一) 病例选择根据临床病史、胸部X线和痰脱落细胞学检查,诊断或疑诊中央型支气管癌患者共 Fiberoptic bronchoscopy is an important method for the early diagnosis of bronchogenic carcinoma, but there are still deficiencies, such as the lack of characteristic changes in early lesions, easily misdiagnosed. Therefore, various methods for labeling tumor tissues have been studied. We used the photosensitizer hematoporphyrin derivative (HPD) as an optical fiber bronchoscope to observe 26 cases of bronchial carcinoma. The report is as follows. Materials and Methods (I) Case selection based on clinical history, chest X-ray and sputum cytology, diagnosis or diagnosis of central bronchogenic carcinoma
