J Clin Oncol:利妥昔单抗联合来那度胺或化疗治疗滤泡性淋巴瘤的长期预后

2022-08-12 MedSci原创 MedSci原创

在既往未治疗过的晚期滤泡性淋巴瘤患者中,R2方案显示出了与R-化疗方案相当的、持久的疗效和安全性,可成为无化疗的替代方案

免疫化学疗法仍然是需要全身治疗的滤泡性淋巴瘤 (FL) 患者的一线金标准;但是,目前已证明 FL 对非化疗方案有免疫反应。来那度胺是一种具有多种特性的免疫调节剂,包括改变细胞因子的产生,增加 T 细胞共刺激和自然杀伤细胞的细胞毒性。已有临床试验证明,来那度胺和利妥昔单抗(即 R2)联合使用在既往未治疗的 FL 患者中显示出有希望的活性和高反应率。

RELEVANCE 试验是一项3期的临床试验,旨在比较来那度胺+利妥昔单抗(R2) vs 利妥昔单抗+化疗(R-化疗)在既往未治疗过的晚期 FL 患者中的疗效和安全性。本文报告了该试验随访6年后的二次分析结果。

在该试验中,1-3a 期 FL 患者被随机(1:1)分至 R2 组或 R-化疗组,继以利妥昔单抗维持。主要终点是120周时的完全缓解率和无进展生存率(PFS)。


两组的PFS和OS

中位随访了72个月后,R2 组和 R-化疗组的6年 PFS 分别是60%和59%(风险比[HR] 1.03)。两组的6年总生存率均估算为89%。两组的中位无进展生存期和总生存期均尚未达到。

R2 组和 R-化疗组进展后的总缓解率分别是61%和59%,进展后的5年估算生存率分别是69%和74%。R2 和 R-化疗组每年的转化率分别为 0.68% 和 0.45%,继发原发性恶性肿瘤的发生率分别是11%和13%(p=0.34)。未观察到新的安全信号。

综上,在既往未治疗过的晚期滤泡性淋巴瘤患者中,R2方案显示出了与R-化疗方案相当的、持久的疗效和安全性,可成为无化疗的替代方案。
