Front Oncol:EGFR突变NSCLC伴有脑膜转移(LM)的特征以及临床预后

2022-01-25 yd2015 MedSci原创

研究表明,EGFR突变NSCLC患者诊断为LM后,使用奥希替尼治疗有更好的临床结果。而且LM病灶控制是延长这些患者总体生存结局的最有效策略。

脑膜转移(LM)是表皮生长因子受体(EGFR)突变的非小细胞肺癌(NSCLC)患者常见的并发症。因此,有来自北京协和医院的团队开展了相关研究,旨在研究LM患者的基因突变类型、治疗策略和临床结果。相关结果发表在Frontiers in Oncology杂志上。

我们回顾性分析了53例EGFR突变NSCLC合并LM患者的临床特征和生存结果。50例患者经脑脊液细胞学检查确诊LM, 3例患者经MRI检查确诊LM。女性略多于男性(30/ 53;56.6%)。从NSCLC诊断到LM诊断的中位时间为18.0个月(范围:0-88)。大多数患者(37/53;69.8%)在LM诊断前或同时有脑转移(BM)。LM诊断前3例(5.7%)患者有WBRT史,30例(56.5%)患者有细胞毒性药物化疗史。大多数患者(n = 47, 88.7%)在发生LM前接受了EGFR TKI治疗,而其余5例患者为未接受EGFR-TKI治疗。

LM诊断后的中位OS为13个月(95% CI = 9.067–16.933)。

LM诊断后治疗LM获得疾病控制(PR和SD)患者的中位OS较PD患者显著延长,分别为17.0个月和2.5个月(HR=6.800; 95% CI = 3.365–13.740; p < 0.001);而颅外病灶获得疾病控制(PR和SD)患者的中位OS也较PD患者显著延长,分别为15.0个月和3.5个月(HR=4.286; 95% CI = 2.089-8.792; p = 0.001)。

LM诊断后血液未检测出EGFR敏感突变患者的中位OS较检测出突变患者明显延长,分别为17.0个月和7.0个月( HR=2.000; 95% CI = 0.965-4.143; p =0.040);LM诊断后使用奥希替尼治疗的患者中位OS较其他治疗方式患者明显延长,分别为15.0 个月和 6.0个月(HR=2.429; 95% CI = 1.234-4.779; p = 0.045)。

Logistic回归分析显示,LM病灶的控制状况是LM诊断后OS的正向预测因素(优势比:10.797;95%CI = 4.102 28.419;p<0.001)。性别、年龄、ECOG PS、 BM状态、脑脊液EGFR突变状态、LM诊断后联合ITC、WBRT和化疗治疗与LM诊断后OS 无显著相关。

综上,研究表明,EGFR突变NSCLC患者诊断为LM后,使用奥希替尼治疗有更好的临床结果。而且LM病灶控制是延长这些患者总体生存结局的最有效策略。
