  • 摘要:   目的  研究布鲁顿酪氨酸激酶(Bruton's tyrosine kinase,BTK)抑制剂治疗复发/难治性中枢神经系统淋巴瘤(relapsed/refractory central nervous system lymphoma,R/R CNSL)的有效性和安全性。  方法  回顾性分析郑州大学第一附属医院2018年10月至2021年10月收治的43例R/R CNSL患者,分别使用BTK抑制剂单药、BTK抑制剂联合化疗、BTK抑制剂联合免疫治疗方案,BTK抑制剂包括伊布替尼、泽布替尼、奥布替尼,初始剂量分别为(420~560)mg/d、320 mg/d、(100~150)mg/d,分析治疗后的最好疗效和不良反应。  结果  BTK抑制剂单药组(A组)、BTK抑制剂联合化疗组(B组)、BTK抑制剂联合免疫治疗组(C组)的客观缓解率(objective response rate,ORR)分别为44.4%、85.7%和76.9%,B组的ORR高于A、C组,原发中枢神经系统淋巴瘤(primary CNSL,PCNSL)患者的ORR(78.6% vs. 66.7%)高于继发中枢神经系统淋巴瘤(secondary CNSL,SCNSL)患者,两者的无进展生存期(progression-free survival,PFS)和总生存期(overall survival,OS)差异均无统计学意义(均P>0.05)。3/4级不良反应主要为白细胞减少、血小板减少、贫血。贫血。  结论  BTK抑制剂单药及联合方案对R/R CNSL患者疗效可,不良反应可耐受。
