JCO:多发性骨髓瘤的自体移植,巩固和维持治疗

2019-01-19 海北 MedSci原创

最近,研究人员设计了一项前瞻性,随机,III期研究,通过比较AHCT,串联AHCT(AHCT / AHCT),AHCT以及随后的4个len,bortezomib和地塞米松(RVD; AHCT + RVD)周期,测试其他干预措施以改善PFS。

单循环马法兰200 mg/m2和自体造血细胞移植(AHCT)以及来那度胺(len)维持治疗可改善符合移植标准的多发性骨髓瘤(MM)患者的无进展生存期(PFS)和总生存期(OS)。

最近,研究人员设计了一项前瞻性,随机,III期研究,通过比较AHCT,串联AHCTAHCT / AHCT),AHCT以及随后的4lenbortezomib和地塞米松(RVD; AHCT + RVD)周期,测试其他干预措施以改善PFS

在开始治疗后12个月内有症状,且70岁或以下无进展的MM患者被随机分配到AHCT / AHCT + lenn = 247),AHCT + RVD + lenn = 254)或AHCT + len n = 257)组。该实验的主要终点是38个月的PFS

研究人群的中位年龄为56岁(范围为2070岁); 24%的患者患有高风险MM73%的患者采用三联药物治疗作为初始治疗,18%的患者在入组时具有完全反应。

AHCT / AHCT + len38个月PFS率为58.5%(95CI51.7%至64.6%),AHCT + RVD + len57.8%(95CI51.4%至63.7%),AHCT + len53.9 95CI47.4%至60%)。对于AHCT / AHCT + lenAHCT + RVD + lenAHCT + lenOS率为81.8%(95CI76.2%至86.2%),85.4%(95CI80.4%至89.3%),和83.7%(95CI78.4%至87.8%),1年的完整反应率分别为50.5%(n = 192),58.4%(n = 209)和47.1%(n = 208)。各治疗组的毒性特征和第二原发性恶性肿瘤的发展相似。

因此,第二次AHCTRVD合并作为AHCT后干预措施,对符合移植标准的MM患者进行前期治疗并未改善PFSOS。单个AHCTlen应该仍然是该人群的标准疗法。
