众所周知套细胞淋巴瘤患者的长期预后极差,欧洲套细胞淋巴瘤协作小组进行了一项研究,探究自体干细胞移植(ASCT)前使用高剂量阿糖胞苷的免疫化学治疗能否改善患者预后。

这项随机、开放、平行组、3期试验在德国、法国、比利时和波兰的128家医院血液肿瘤科或私人诊所进行。≤65岁的未经治疗的II–IV期套细胞淋巴瘤患者随机分为六个疗程的R-CHOP(利妥昔单抗联合环磷酰胺、阿霉素、长春新碱和强的松)随后清髓性放化疗和ASCT(对照组);或六疗程交替 R-CHOP或R-DHAP(利妥昔单抗加地塞米松、大剂量阿糖胞苷、顺铂)随后含大剂量阿糖胞苷处理方案和ASCT(阿糖胞苷组)。根据研究组和国际预后指数对患者进行分层分析。主要终点是随机化后病情稳定至少四个周期的诱导化疗后到治疗失败的时间间隔、疾病进展或者任何原因的死亡。

该研究共纳入了497名患者,中位数年龄55岁[IQR 49–60],对照组和阿糖胞苷组分别有249人和248人,最终分别有234人和232人进行了初步分析。中位数随访6.1年(95% CI 5.4–6.4),阿糖胞苷组到治疗失败的时间明显更长(中位数9.1年[95% CI 6.3– ],5年率65% [95% CI 57–71] vs. 3.9 年 [3.2–4.4], 40% [33–46]; HR 0.56; p=0.038))。在诱导化疗期间,接受大剂量阿糖胞苷的患者3或4级血液学毒性增加(血红蛋白 71/241 [29%] vs. 19/227 [8%];血小板176/240 [73%] vs 21/225 [9%]),3级或4发热性中性粒细胞减少的发生更多(39/230 [17%] vs. 19/224 [8%]),1级或2级肾毒性增加(肌酐102/236 [43%] vs. 22/224 [10%])。ASCT相关死亡在两组间无差异(8[3.4%])。

研究结果表明,≤65岁的套细胞淋巴瘤患者行ASCT前,可以考虑在标准治疗的基础上添加含大剂量阿糖胞苷的免疫化学治疗。
