摘　　要：目的:探讨奥布替尼联合大剂量甲氨蝶呤(high dose methotrexate,HD-MTX)一线治疗老年高危原发中枢神经系统淋巴瘤的近期疗效和不良反应,并随访生存情况。方法:选择2016年6月-2022年6月在福建省立医院初次确诊的原发中枢神经系统弥漫大B细胞淋巴瘤老年高危患者25例,回顾性收集患者的临床资料。随访截止至2022年12月。15例患者接受替莫唑胺联合HD-MTX方案至少4个疗程,序贯来那度胺维持治疗;10例患者接受奥布替尼联合HD-MTX方案至少4个疗程,序贯奥布替尼维持治疗。观察两组患者治疗后近期疗效和不良反应,采用Kaplan-Meier分析无进展生存期(PFS)和肿瘤进展时间(TTP)。结果:奥布替尼联合HD-MTX方案组客观有效率(ORR)、2年中位PFS与替莫唑胺联合HD-MTX方案组比较无统计学差异(ORR:100%vs66.7%;2年PFS:16个月vs15个月,P>0.05),而两组2年中位TTP比较具有统计学差异(未达到vs12个月,P<0.05)。两组患者的胃肠反应、骨髓抑制、肝肾功能损伤、心脏毒性、肺炎和出血等不良反应相比较差异均无统计学意义(P>0.05)。结论:奥布替尼联合HD-MTX并序贯奥布替尼维持治疗初治老年高危PCNSL患者,近期疗效好,安全可靠,值得临床推广。Objective:To explore the short-term efficacy and adverse reactions of orelabrutinib combined with highdose methotrexate(HD-MTX)in the first-line treatment of elderly high-risk primary central nervous system lymphoma(PCNSL),as well as the survival of patients.Methods:Twenty-five elderly patients with high-risk primary central nervous system diffuse large B-cell lymphoma admitted to Fujian Provincial Hospital from June2016to June2022were enrolled in this study,and complete clinical data from all patients were collected retrospectively,and the cut-off for follow-up was December2022.15patients had received temmozolomide combined with HD-MTX regimen for at least four cycles,sequential lenalidomide maintenance therapy,while10patients had received orelabrutinib combined with HD-MTX regimen for at least four cycles,sequential orelabrutinib maintenance therapy.The short-term efficacy and adverse reactions of the two groups of patients after treatment were observed.Kaplan-Meier was used to analyze the progression-free survival(PFS)and time to progression(TTP).Results:The objective response rate(ORR)and2-year median FPS of orelabrutinib combined with HD-MTX regimen group were similar to the temozolomide combined with HD-MTX regimen group(ORR:100% vs66.7%;2-year median PFS:16months vs15months,P<0.05).The2-year median TTP of the orelabrutinib+HD-MTX regimen group was better than that of the temozolomide+HD-MTX regimen group(not reached vs12months,P<0.05).There were no significant differences in adverse reactions such as gastrointestinal reactions,bone marrow suppression,liver and kidney damage,cardiotoxicity,pneumonia and bleeding between these two groups(P>0.05).Conclusion:For elderly patients with high-risk PCNSL,orelabrutinib combined with HD-MTX has reliable short-term efficacy,good safety,and tolerable adverse reactions,which is worthy of clinical promotion.
