就采用血卟啉衍化物光动力疗法(HpD-PT)治疗X线阴性肺癌的经验进行了总结.材料与方法全部患者均经活检确定为气管支气管鳞癌,普通胸片和CT无扩散表现,适宜手术治疗.采用连续波氩染料离子激光激发蓝光碱性蕊香红激光器产生波长630nm的激光,经石英光纤传送至治疗部位.激光治疗前 The experience of using hematoporphyrin derivative photodynamic therapy (HpD-PT) to treat X-ray-negative lung cancer was summarized. Materials and Methods All patients were identified by biopsy as tracheobronchiolar squamous cell carcinoma, normal chest radiographs and CT without proliferation performance. Suitable for surgical treatment. The continuous wave argon dye ion laser is used to excite the blue rhodamine red laser to generate a laser beam with a wavelength of 630 nm and transmitted through the silica fiber to the treatment site. Before laser treatment
