Blood:PD-1封闭可提高复发性/难治性经典霍奇金淋巴瘤患者的缓解率,并延长其缓解时间,但会增加其免疫毒性风险

对于不适合进行自体造血干细胞移植(HCT)或移植后复发的复发性/难治性(R/R)典型霍奇金淋巴瘤(cHL)患者,PD-1封闭是一种有效疗法。尽管抗PD-1单克隆抗体(mAbs)可提高缓解率、延迟缓解持续时间,但就目前的数据表明采用该疗法的大部分患者的病程终还是会进展。很多患者经抗PD-1 mAbs治疗后,即可接受异体HCT(allo-HCT),因此,在这种情况下,allo-HCT仍是目前唯一证实的

对于不适合进行自体造血干细胞移植(HCT)或移植后复发的复发性/难治性(R/R)典型霍奇金淋巴瘤(cHL)患者,PD-1封闭是一种有效疗法。尽管抗PD-1单克隆抗体(mAbs)可提高缓解率、延迟缓解持续时间,但就目前的数据表明采用该疗法的大部分患者的病程终还是会进展。很多患者经抗PD-1 mAbs治疗后,即可接受异体HCT(allo-HCT),因此,在这种情况下,allo-HCT仍是目前唯一证实的可治愈cHL的疗法。

但是,有报告提示在这种状况下,allo-HCT可能会增加早期移植相关毒性风险,可能是由于PD-1阻滞的持续效应导致的。而且,很多进行allo-HCT的R/R cHL患者在移植后会复发,而且多数情况下治疗选择有限。在近期研究中,再次证实PD-1阻滞可提高缓解率,但同时伴随免疫毒性风险增加。

对于PD-1封闭究竟是在allo-HCT前还是allo-HCT后应用仍存在很多问题,特别是涉及到PD-1封闭后allo-HCT的可行性、预后、最佳时间和方法时。

尽管前瞻性数据不足,但这些问题不可避免,而且必须由对晚期cHL患者进行日常护理的临床医生来解决。Charles Herbaux等人在此提供了一个工作组基于现有数据和经验的统一建议,以指导制定医疗决策,直到获得更为明确的数据。
