Abstract
背景与目的免疫新辅助为局部晚期肺癌治疗打开新局面。本研究探讨局部晚期中央型非小细胞肺癌(non-small cell lung cancer, NSCLC)患者在化疗联合免疫新辅助治疗后机器人辅助支气管袖状切除的安全性与可行性。方法回顾性分析2020年8月-2021年2月接受化疗联合免疫新辅助治疗后支气管袖状切除的13例局部晚期中央型NSCLC患者的临床资料,患者依据手术方式不同分为开胸手术(thoracotomy bronchial sleeve resection, TBSR)组和机器人辅助手术(robot-assisted bronchial sleeve resection, RABSR)组,比较两组患者肿瘤学特征、术中和术后的资料。结果两组患者手术顺利,术后病理证实均实现肿瘤R0切除,RABSR组患者无中转开胸。TBSR组中患者影像学部分缓解(partial remission, PR)率为71.43%,主要病理缓解(major pathological remissions, MPR)率为42.86%,完全病理缓解(complete pathological response, pCR)率为28.57%,RABSR组分别为66.67%、50.00%和33.33%。两组患者平均手术时长、淋巴结清扫数目、术中平均出血量、术后平均引流时间、术后住院时间无明显差异,但是RABSR组支气管吻合时间相对较短。两组患者均预后良好,顺利出院,术后90 d死亡率为0。结论局部晚期中央型NSCLC患者经过化疗联合免疫新辅助治疗后可实现缩瘤降期、增加R0切除率,支气管袖状切除安全可行。在遵循手术安全性和实现肿瘤R0切除两个原则的前提下可优先选择机器人行袖状切除。
