【摘要】 目的:探究继发中枢神经系统淋巴瘤的诱导治疗疗效及预后不良因素。方法:回顾性收集广东省人民医院2010至2021年间确诊为继发中枢神经系统淋巴瘤患者的临床资料,采用回顾性队列研究对所有患者及分组患者进行疗效和预后的生存分析,多因素Logistic回归分析探讨影响患者预后的不良因素。结果:纳入37例合并继发累及中枢的弥漫大B细胞淋巴瘤患者,2年总生存率(OS)为46.01%,中位生存期为18.1个月;高剂量甲氨蝶呤治疗组与替莫唑胺治疗组的2年OS率分别为34.3%和61%,中位生存期分别为8.7和38.3个月,中位无进展生存期分别为8.1和47个月。多因素Logistic回归分析结果显示,患者生存期与年龄、性别、IPI、Ann Arbor分期有关。CD79B、KMT2D、CXCR4、ERBB2、TBL1XR1、BTG2、MYC、MYD88、PIM1基因突变患者的中位生存期为8.2个月,低于总体水平。结论:高剂量甲氨蝶呤联合替莫唑胺的一线治疗可改善患者预后,且早期应用基因检测有利于评估预后。更多还原

【Abstract】 Objective:To explore the therapeutic efficacy and prognostic factors of induction therapy for secondary central nervous system lymphoma(SCNSL).Methods:Clinical data of patients diagnosed with SCNSL from 2010 to 2021 at Guangdong Provincial People’ s Hospital were retrospectively collected.A retrospective cohort study was performed on all and grouped patients to analyze the efficacy and survival.Multivariate logistic regression analysis was used to explore the adverse prognostic factors.Results:Thirty-seven diffuse large B-cell lymphoma patients with secondary central involvement were included in the research.Their 2-year overall survival(OS) rate was 46.01% and median survival time was 18.1 months.The 2-year OS rates of HD-MTX group and TMZ group were 34.3% and 61%,median survival time were 8.7 and 38.3 months,and median progression-free survival time were 8.1 and 47 months,respectively.Multivariate logistic regression analysis showed that age,sex,IPI,Ann Arbor stage were correlated with patient survival time.The median survival time of patients with CD79B,KMT2D,CXCR4,ERBB2,TBL1XR1,BTG2,MYC,MYD88,and PIM1 mutations was 8.2 months,which was lower than the overall level.Conclusion:HD-MTX combined with TMZ as the first-line strategy may improve patient prognosis,and early application of gene sequencing is beneficial for evaluating prognosis.更多还原
