单纯放疗在非小细胞肺癌(NSCLC)中的治疗作用是一个值得探讨的问题.目前的报道多集中于Ⅰ期和Ⅲ期患者,而Ⅱ期患者由于仅占NSCLC总数的10%,有关其治疗效果及预后因素分析的研究相对较少.对于病理分期为Ⅱ期的患者,手术切除是首选方法,其疗效介于Ⅰ期和Ⅲ期之间.然而临床分期为Ⅱ期的患者单纯放疗的效果尚未得到深入研究,临床同侧肺门淋巴结受累(N_1)对于预后的意义也尚未明确.作者复习了758例单纯放疗的NSCLC病例,以明确Ⅱ期患者单纯放疗的临床过程及预后因素,并对临床无纵隔淋巴结肿大、仅有同侧肺门淋巴结肿大(N_1)的预后意义作出了评
The therapeutic effect of radiotherapy alone in non-small cell lung cancer (NSCLC) is a problem worth investigating. The current reports mostly focus on patients of stage I and III, and stage II patients only account for 10% of the total number of NSCLC. There are relatively few studies on the effects and prognostic factors. For patients with pathologic stage II, surgical resection is the preferred method. The effect is between stage I and stage III. However, clinical stage is the effect of radiotherapy alone in stage II patients. Without further study, the significance of clinically involved lymph node involvement (N_1) is not yet clear. The author reviewed 758 cases of NSCLC with radiotherapy alone to clarify the clinical course and prognostic factors of patients with stage II radiotherapy alone. Clinical prognostic significance of no mediastinal lymphadenopathy and only ipsilateral hilar lymphadenopathy (N_1)
