TL;DR
This study examines the effectiveness and prognosis of treating adult Burkitt lymphoma with rituximab and intensive chemotherapy, finding it to be effective with certain risk factors affecting outcomes.
Contribution
The study provides new insights into the efficacy and prognostic factors of rituximab-based intensive immunochemotherapy for adult Burkitt lymphoma.
Findings
The 5-year progression-free and overall survival rates were 76.7% with rituximab and intensive chemotherapy.
High BL-IPI scores and failure to achieve complete remission were linked to worse outcomes.
Autologous stem cell transplantation improved outcomes for high-risk patients responsive to initial treatment.
Abstract
探讨利妥昔单抗联合高强度化疗治疗散发性成人伯基特淋巴瘤(BL)的治疗效果及预后因素。 回顾性分析2011年6月至2023年2月在中国医学科学院血液病医院诊治的30例初诊BL患者的临床和生存信息,采用Kaplan-Meier法计算生存率,运用Log-rank检验对预后因素进行单因素分析。 30例患者的中位年龄为43(24~66)岁,男女比例为3∶2。80.0%患者伴结外侵犯、53.3%伴骨髓侵犯、10.0%伴中枢神经系统侵犯,Ann Arbor分期Ⅲ~Ⅳ期占86.7%。伯基特淋巴瘤国际预后指数(BL-IPI)评分为低危(0分)、中危(1分)和高危(≥2分)者分别占比20.0%、43.3%和36.7%。所有患者均接受利妥昔单抗联合高强度化疗作为初始诱导治疗方案,客观缓解率和完全缓解率分别为80.0%和76.7%。中位随访时间为49(6~153)个月,5年的无进展生存(PFS)率和总生存(OS)率均为(76.7±7.7)%。4例局限期患者均获得持续的完全缓解(CCR)。10例对诱导治疗敏感的高危、进展期患者序贯一线auto-HSCT巩固治疗,除1例伴中枢神经系统侵犯的患者发生早期疾病进展而死亡,其余9例均获得CCR。BL-IPI低危、中危和高危组患者的5年PFS率分别为(83.3±15.2)%、100.0%和(45.5±15.0)%(P=0.0069),OS率分别为(83.3±15.2)%、100.0%和(45.5±15.0)%(P=0.0075)。诱导治疗期间的主要不良反应为骨髓抑制和继发感染,但均可对症处理。单因素分析显示,结外侵犯部位≥2个(HR=4.90,95% CI 1.02~23.45,P=0.0329)、BL-IPI评分≥2分(HR=12.62,95% CI 2.59~61.62,P=0.0021)和诱导治疗未达首次完全缓解(CR1)(HR=31.86,95% CI 4.19~242.20,P<0.0001)与更短的PFS期相关。…
