摘 要:背景与目的:多项荟萃分析(Meta-analysis)及研究显示,复发性高级别胶质瘤即便后续综合治疗,其客观反应率(objective response rate, ORR) 、6个月无进展生存率(progression- free survival, PFS)仍然较低。因此,探索复发性高级别胶质瘤新的治疗策略十分必要。本文总结我们应用尼莫司汀(nimustine.ACNU)联合贝伐珠单抗(bevacizumab,Bey)治疗7例复发性高级别胶质瘤的临床经验.探讨其安全性与近期疗效。方法:7例复发性高级别胶质瘤均行ACNU联合Bev治疗。化疗方案的选择基于肿瘤组织DNA甲基转移酶(O^6-methylguanine-DNA methyltransferase, MGMT)的免疫组织化学检测结果以及甲基化特异PCR(MSP-PCR)检测MGMT启动子甲基化程度。MGMT阴性表达或MGMT启动子甲基化程度高者,给予ACNU,80-100mg/(m2·d),d1,静脉输注,四周方案;Bey用法:5mg,kg,静脉输注,每两周一次。结果:7例患者共接受ACNU联合Bev治疗28次,中位3次(3-6次)。患者均可评价客观疗效,完全缓解(complete remission,CR)2例(28.6%),部分缓解(partial remission,PR)3例(42.9%),微效(minimal remission,MR)1例(14-3%),进展(progressive disease,PD)1例(14.3%)。疾病控制率(CR+PR+MR)办85.7%。中位PFS为4.2月(95%CI:3-7月).6个月的PFS为41.6%。最严重不良反应是Ⅳ度粒细胞减少症与白细胞减少症.各1例次(3.6%),Ⅲ度粒细胞减少症与白细胞减少症各2例次(7.1%)。最常见的轻至中度不良反应包括Ⅱ度脱发10例次(35.7%)、Ⅱ度粒细胞减少症与白细胞减少症各4例次(14.3%)、腹泻3例次(10.7%)、Ⅱ度疲乏2例次(7.1%)、高血压2例次(7.1%)。结论:ACNU联合Bev治疗复发性高级别胶质瘤患者是安全的.疗效也令人较满意。BACKGROUND & OBJECTIVE: Previous Meta-analyses and correlated studies showed that albeit recurrent patients with high-grade gliomas (HGG) received comprehensive therapies, the rates of objective response rates (ORR) and progression-free survival(PFS)at 6 months remained low. Thus, it is necessary to discuss the new strategies for recurrent HGGs. This article was to evaluate the efficiency and side effects of regimen of Nimustine (ACNU)combined with Bevacizumab (Bev). METHODS: The personalized regimen of chemotherapy was selected based on MGMT expression of the tumor, and MGMT promoter methylation status. Patients with MGMT-negative tumors, or MGMT promoter methylated had received 200 mg/m2 of ACNU infusion intravenously once 4 weeks, and 5mg/kg of bevacizumab infusion intravenously once 2 weeks until unacceptable toxicity or tmnor progression occurred. RESULTS: Seven patients received a total of 28 cycles of regimens of ACNU combined with Bev ranging from 3 to 6 (median 3 times). Complete remission (CR), partial remission (PR),ininimal remission (MR) and progressive disease (PD) were found in two patients (28.6%), three patients (42.9%), one patients (14.3%), and one patients(14.3%), respectively. Disease control rate (CR +PR+ MR)was 85.7%. The median progression free survival (PFS) was 4.2 months (95%CI:3-7)and the rate of PFS at 6 months was 41.6%. As to the side effects, myelosuppression including neutropenia (grade 4 and grade 3) and leukopenia (grade 4 and grade 3) were the most connnon high grade toxicities, occurring in 3.6 % (1 / 28) , 7.1% (2 / 28), 3.6 % (1 / 28) and 7.1% (2 / 28), respectively. The most frequent toxicities were alopecia (35.7%), neutropenia (grade 2) (14.3%), and lenkopenia (grade 2) (14.3%), diarrhea (10.7%), fatigue (7.1%), and hypertension (7.1%). CONCLUSION: RRegimen of ACNU combined with Bey has moderate activity in patients with high-grade gl
