【摘要】：目的探讨利妥昔单抗在慢性淋巴细胞白血病(CLL)患者中的疗效。方法回顾性分析本院一线应用氟达拉滨+环磷酰胺±利妥昔单抗方案或环磷酰胺+长春新碱+泼尼松±蒽环类药物±利妥昔单抗方案治疗的CLL患者病例资料,比较利妥昔单抗及不同化疗方案的疗效。结果一线采用含利妥昔单抗方案治疗的患者为72例(43.6%);不含利妥昔单抗方案治疗的患者为93例(56.4%)。利妥昔单抗治疗组完全缓解(CR)率和总体反应率(ORR)均显著高于未应用利妥昔单抗治疗组(38.9%比21.5%,P=0.015;83.3%比60.2%,P=0.001)。利妥昔单抗治疗组中位无进展生存期(PFS)为53.0(27.0~79.0)个月,中位总生存时间(OS)为112.0(81.1~142.9)个月,而未应用利妥昔单抗治疗组中位PFS为28.0(18.3~37.7)个月(P=0.094),中位OS为89.0(72.0~106.0)个月(P=0.109),两组比较差异无统计学意义。按是否伴有高危遗传学因素(伴17p缺失或11q缺失)将患者分成高危组和非高危组,高危组联合利妥昔单抗治疗患者可显著提高ORR(86.4%比53.3%,P=0.012),但PFS[14.5(7.9~21.1)个月比20.5(10.7~30.3)个月,P=0.699]及OS[96.0(55.3~136.7)个月比74.0(48.0~100.0)个月,P=0.366]无优势;而在非高危组中,应用利妥昔单抗后患者PFS有延长趋势[71.0(55.3~86.7)个月比38.5(17.7~59.3)个月],但差异无统计学意义(P=0.050)。结论 CLL患者应用利妥昔单抗联合化疗可获得更高的CR率、ORR,并对不伴染色体17p缺失或11q缺失患者的PFS有改善趋势。
[Abstract]:Objective to investigate the efficacy of rituximab in patients with chronic lymphoblastic leukemia (CLL). Methods the data of CLL patients treated with fludarabine cyclophosphamide + rituximab regimen or cyclophosphamide vincristine prednisone + anthracycline 卤rituximab regimen were analyzed retrospectively. the therapeutic effects of rituximab and different chemotherapy regimens were compared. Results 72 patients (43.6%) were treated with rituximab regimen and 93 patients (56.4%) without rituximab regimen. The complete remission rate and total response rate of (ORR) in rituximab group were significantly higher than those in non-rituximab treatment group (38.9% vs 21.5%, P 鈮，
