来自2015年美国临床肿瘤学会年会的最新报道:
Background: The role of rituximab (R) maintenance therapy (MT) in B-cell lymphoma is controversial. We reviewed data from clinical studies and conducted a meta-analysis to evaluate the efficacy and safety of R MT in follicular lymphoma (FL), diffuse large B-cell lymphoma (DLBCL) and mantle cell lymphoma (MCL).
背景:美罗华维持对B细胞淋巴瘤的作用存在争议。我们通过回顾各种临床试验的数据对美罗华维持在滤泡,弥漫大B和套细胞淋巴瘤中的效果和安全性进行了荟萃分析。
Methods: PubMed, ASCO and ASH databases were searched for eligible clinical studies to date that investigated survival outcomes (OS, PFS, EFS and/or TTP) and adverse events of R MT in FL, DLBCL and MCL. Pooled hazard ratios (HRs) for survival outcomes and risk ratios (RRs) for dichotomous data with 95% CI were calculated using Comprehensive MetaAnalysis (v2).
方法:在PubMed,ASCO和ASH数据库中查找相关临床研究,调查滤泡、弥漫大B和套细胞淋巴瘤美罗华维持的生存转归的各项指标以及不良事件。
Results: 22 clinical studies of 6785 patients, including 15 randomized controlled trials (RCTs) enrolling 5029 patients, were included in this meta-analysis. In RCTs, R MT significantly prolonged PFS (HR = 0.60, 95% CI = 0.52-0.68, P < 0.001) and OS (HR = 0.79, 95% CI = 0.69-0.93, P = 0.005) in B-cell lymphoma. Improvement of PFS with R MT was demonstrated in all types of lymphoma studied. R MT increased OS in FL (HR = 0.76, 95% CI = 0.61-0.94, P = 0.010) but not DLBCL (HR = 0.88, 95% CI = 0.64-1.21, P = 0.425) or MCL (HR = 0.77, 95% CI = 0.47-1.27, P = 0.303) in RCTs. The survival benefits remained after including non-randomized clinical studies and retrospective studies. R MT increased the risks of neutropenia (RR = 1.82, 95% CI = 1.40-2.37, P < 0.001) and infection (RR = 2.49, 95% CI = 1.61-3.85, P < 0.001) but not cardiac dysfunction (RR = 1.61, 95% CI = 0.73-3.57, P = 0.242).
结果:这项分析包括了22个临床研究,共6785例病人,其中15个是随机试验,共入组了5029例病人。在随机研究中,美罗华维持显著延长了PFS(无进展生存期)和OS(总生存期)。美罗华维持改善了所有参加研究的淋巴瘤类型的PFS。在随机研究中,美罗华维持还提高了滤泡性淋巴瘤的OS,但是对弥漫大B和套细胞的OS没有改善。加入非随机试验和回顾性试验的数据后,生存获益依然保持。美罗华维持增加了中性粒细胞减少症和感染的风险,但是对心脏功能没有影响。
Conclusions: R MT significantly improved PFS in FL, DLBCL and MCL as well as OS in FL. Whether R MT improves OS in DLBCL and MCL needs further study.
结论:美罗华维持显著改善了滤泡,弥漫大B和套细胞的PFS,以及滤泡的OS。是否能够提高弥漫大B和套细胞的OS有待进一步研究。
