Early-stage non-small cell lung cancer (ES-NSCLC) currently represents a minority of all NSCLC diagnoses but, with ongoing refinement and improvement of treatment approaches, is a group with increasing likelihood of long-term disease control and survival. A significant proportion of this population will not be optimal candidates for definitive surgical resection due to tumor characteristics, patient frailty, or comorbid status. The clinical evidence to support the use of stereotactic body radiation therapy (SBRT) in patients with medically inoperable stage I NSCLC is growing as long-term data are obtained. In this review, initial workup, SBRT delivery considerations, recent trial data, and post-treatment surveillance of this population are discussed.
早期非小细胞肺癌(ES-NSCLC)目前在所有NSCLC诊断病例中占少数,但随着治疗方法的不断完善和改进,这一群体实现长期疾病控制和生存的可能性越来越大。由于肿瘤特征、患者身体虚弱或合并症状态,相当一部分这类患者并非确定性手术切除的最佳候选人。随着长期数据的获得,支持在医学上无法手术的I期NSCLC患者中使用立体定向体部放射治疗(SBRT)的临床证据正在增加。在本综述中,讨论了该人群的初始检查、SBRT实施注意事项、近期试验数据以及治疗后监测。
