一项由奥地利的协作组主导的国际性多中心随机三期临床试验最近通过欧洲血液病协会发表了有关结果,这项研究涉及侵袭性B细胞淋巴瘤患者首次缓解后用美罗华维持治疗。摘要如下:
Rituximab Maintenance For Patients With Aggressive B-Cell Lymphoma In First Remission:
侵袭性B细胞淋巴瘤患者首次缓解后用美罗华维持治疗
Results Of The Randomized NHL13 Trial
NHL13随机试验的结果
We investigated rituximab maintenance therapy in patients with diffuse large B-cell lymphoma (N=662) or follicular lymphoma grade 3b (N=21) in first complete remission. Patients were randomised for rituximab maintenance (N=338) or observation (N=345).
我们对弥漫大B淋巴瘤患者(662例)和滤泡性淋巴瘤3B级患者(21例)在首次缓解后接受美罗华维持治疗进行了研究。患者被随机分配到美罗华维持组(338例)和观察组(345例)。
At a median follow-up of 45 months, event-free survival (primary endpoint) at 3 years was 80.4% for rituximab maintenance vs. 76.5% for observation. This difference was not significant for the intent to treat population (Likelihood ratio p=0.0670). The hazard ratio by treatment arm was 0.79 (95% confidence interval 0.57-1.08; p=0.1433). The secondary endpoint progression-free survival was also not met for the whole population (Likelihood ratio p=0.3646).
在中位45个月的随访时间内,3年无事件生存率(第一终点)维持组是80.4%,观察组是76.5%,区别不明显。治疗组的风险比是0.79%。试验的第二终点无进展生存率全组还没有达到。
Of note, rituximab maintenance was superior to observation when treatment arms only were compared (Hazard ratio: 0.62; 95% confidence interval 0.43-0.90; p=0.0120). Overall survival remained unchanged (92.0 vs. 90.3%).
值得注意的是,如果仅比较治疗组那么美罗华维持优于观察。总生存率没有变化(92%对90.3%)。
In subgroup analysis male patients benefitted from rituximab maintenance regarding event-free survival (84.1% vs. 74.4%) (Hazard ratio: 0.58; 95% confidence interval 0.36-0.94; p=0.0267) and progression-free survival (89.0% vs. 77.6%) (Hazard ratio: 0.45; 95% confidence interval 0.25-0.79; p=0.0058).
在亚组分析中男性患者从无事件生存率(84.1%对74.4%)和无进展生存率(89%对77.6%)上看获益于美罗华维持。
Women had more grade 3/4 adverse events (p=0.0297) and infections (p=0.0341). Men with a low International Prognostic Index treated with rituximab had the best outcome.
女性患者有更多的3/4级负面事件和感染。男性患者具有较低的国际预后指数的用美罗华治疗有最好的结果。
In summary, rituximab maintenance in first remission after R-CHOP-like treatment did not prolong event-free, progression-free or overall survival of patients with aggressive B-Non Hodgkin lymphoma. The significantly better outcome of men warrant further studies prior to the routine use of rituximab maintenance in men with low International Prognostic Index.
总之,侵袭性B细胞非霍奇金淋巴瘤患者在接受R-CHOP类治疗首次缓解后用美罗华维持不能够延长无事件、无进展和总生存率。男性患者的较好结果提示在对具有较低的国际预后指数的男性患者进行常规美罗华维持之前还需要进一步研究。
