非小细胞肺癌寡转移的立体定向放射治疗研究

非小细胞肺癌(Non-small cell lung cancer,NSCLC)是除小细胞肺癌以外所有类型的肺癌,脑、骨、肝及肾上腺为最常见的远处转移部位。在NSCLC远处转移患者中,并非都是多发的、广泛的,有近7%的患者表现为肺外孤立性转移。这种特殊形式的晚期肿瘤转移状态称之为NSCLC寡转移。寡转移的治疗以局部治疗为主,局部治疗主要措施包括立体定向放疗、手术切除、射频消融等。本文主要探讨立体定向放射治疗(Stereotactic radiotherapy,SRT)对NSCLC在常见远处转移脏器寡转移的作用。

Study of oligodendrocyte metastasis in non-small cell lung cancer by stereotactic radiotherapy

Non-small cell lung cancer(NSCLC)is the most common type of distant metastasis in all types of lung cancer except for SCLC,including brain,bone,liver and adrenal gland.Of the patients with distant metastases in NSCLC,not all cases are multiple and extensive,with nearly 7% of patients presenting with isolated extrapulmonary metastases.This particular form of advanced tumor metastasis is called NSCLC oligometastatic.Treatment of oligometastatic is mainly local treatment,which includes stereotactic radiotherapy(STR),surgical resection and radiofrequency ablation.The aim of this article is to discuss the effect of SRT on the micrometastasis of common distant metastatic organs in NSCLC.
