Lancet Oncol:小细胞肺癌颅内转移后的放疗选择

2022-06-05 MedSci原创 MedSci原创

对于发生颅内转移的小细胞肺癌患者,立体定向放疗和全脑放疗后的生存预后不相上下

颅内转移性疾病 (IMD) 是癌症患者可致死的严重并发症。小细胞肺癌 (SCLC) 患者是颅内转移性疾病的高危人群。既往研究发现,多大40-60%的小细胞肺癌患者会发生颅内转移。

虽然立体定向放疗(SRS)已取代全脑放疗(WBRT)作为大部分实体癌颅内转移的一线治疗方案,但WBRT仍是SCLC患者颅内转移的一线治疗方法。本研究旨在比较SRS与WBRT治疗SCLC患者颅内转移的疗效,同时评估SRS治疗的预后。


研究流程

这是一项系统回顾和荟萃分析,研究人员从MEDLINE、Embase、CENTRAL和grey图书馆数据库中检索2020年3月23日前发表的关于SCLC患者采用SRS治疗颅内转移的对照试验和队列研究。主要终点是总生存率。


在Meta分析中,SRS vs WBRT±SRS强化的总生存期

共评估了3823项研究,其中31项符合纳入标准。7项研究共18130位患者被纳入Meta分析。与WBRT治疗(无论有无加用SRS强化)或单用WBRT相比,SRS治疗后的总生存期均更长(风险比[HR]分别是0.85和0.77);SRS治疗与WBRT+SRS强化治疗的总生存期无明显差异。

在单臂研究(14项研究,共1682位患者)中,SRS组的汇总中位总生存期是8.99个月。SRS和WBRT治疗之间的无颅内进展生存期无明显差异(HR 0.99)。SRS治疗6个月时的局部颅内控制率为81%,远处颅内控制率为66%;12个月时局部颅内控制率为78%,远处颅内控制率为58%。因缺乏数据,不能对比SRS和WBRT±SRS的局部和远处颅内控制率。

综上,该研究结果提示,对于发生颅内转移的小细胞肺癌患者,立体定向放疗和全脑放疗后的生存预后不相上下。
