尽管放射治疗已日趋成为肺癌保守治疗的重要方法之一,但常规分割照射对肺癌局部控制仍不理想,放疗后的局部复发和进展率仍在50～70％左右。为了寻求一种照射方法既能提高肿瘤局部控制率,又不致增加肺组织的放射并发症,我院采用超分割、分段和常规分割三种照射方法,对不能手术和不宜手术的肺鳞状细胞癌进行前瞻性临床研究,现作初步分析。 Although radiation therapy has increasingly become one of the important methods for conservative treatment of lung cancer, conventional segmentation irradiation is still not ideal for local control of lung cancer, and the local recurrence and progression rate after radiotherapy is still about 50 to 70%. In order to seek an irradiation method that can not only increase the local control rate of the tumor but also not increase the radiological complications of the lung tissue, the hospital used ultra-segmentation, segmentation, and conventional segmentation to irradiate the inoperable and inoperable lungs. The prospective clinical study of cell carcinoma is performed for preliminary analysis.
