约10％～15％的支气管肺癌患者在疾病的发展过程中出现严重的气道阻塞。除小细胞肺癌外,其它类型的肺癌引起气道阻塞症状的标准疗法是体外局部放疗。体外放疗受周围组织耐受性的制约,气道内局部放疗(支气管镜植入大剂量或小剂量的放射状颗粒或间质内放入~(125)I,~(198)Au,~(192)Ir,~(60)Co)可反复应用,对肿块治疗效果好,但症状缓解速度比摘除或激光慢一些。将导管留置于肿瘤部位也是有效的。这些导管在放疗科医生的合
About 10% to 15% of lung cancer patients have severe airway obstruction during the development of the disease. In addition to small cell lung cancer, the standard therapy for airway obstruction symptoms in other types of lung cancer is localized external radiotherapy. In vitro radiotherapy is constrained by the tolerance of the surrounding tissue. Local radiotherapy in the airway (bronchoscopic implantation of high- or low-dose radioactive particles or interstitials into ~(125)I, ~(198)Au, ~(192) Ir, ~ (60) Co) can be repeatedly applied to the treatment of tumors, but the relief of symptoms is slower than removal or laser. It is also effective to leave the catheter at the tumor site. These catheters are the combination of radiotherapists
