美罗华治疗B细胞性非霍奇金淋巴瘤的临床观察

目的:比较美罗华单药或联合化疗和单用CHOP方案治疗初治的B细胞性非霍奇金淋巴瘤的临床疗效及不良反应。方法:采用同期非随机对照的前瞻性研究方法,将51例初治B细胞淋巴瘤患者分为美罗华组和CHOP组,前组24例,采用美罗华单药或联合化疗;后组27例,单用CHOP方案化疗。3～6疗程后比较2组的疗效及不良反应。结果:美罗华组完全缓解(CR)率83.3%(20/24),总有效率(OR)95.8%(23/24);CHOP组CR率55.6%(15/27),OR率66.7%(18/27),2组疗效差异有统计学意义(P<0.05)。美罗华组2年的总生存率为70.8%,CHOP组为40.7%,美罗华组优于CHOP组(P<0.05)。结论:美罗华治疗初治B细胞淋巴瘤可取得较好疗效,2年生存率高,不良反应能耐受。

Clinical study of rituximab in treating B-cell non-Hodgkin lymphoma

Objective:To compare the efficacy of Rituximab with or without chemotherapy and CHOP alone on newly diagnosed patients with B-cell non-Hodgkin lymphoma(NHL), and to analyze their toxicities.Method:A total of 51 newly diagnosed patients with B-cell NHL were divided into 2 groups prospectively with concurrent control: 24 cases in Rituximab group were administered Rituximab with or without chemotherapy, the remaining 27 cases in CHOP group were treated with CHOP regimen only. All cases were evaluated after 3~6 courses.Result:The complete remission (CR) rate and totol response rate in Rituximab group were 83.3%(20/24) and 95.8%(23/24) respectively, while those corresponding rates in CHOP group were 55.6%(15/27) and 66.7%(18/27), respectively. The therapeutic efficacy differences between two groups showed statistical significance(P<0.05). The 2-year overall survival rate was significantly higer in Rituximab group than in CHOP group(70.8% vs. 40.7%, P<0.05).Conclusion:Comparing with CHOP group, Rituximab group showed higher therapeutic effects and 2-year overall survival rate. Rituximab can be used with good tolerance.
