Lancet Haematol:产前治疗or产后治疗,霍奇金淋巴瘤孕妇患者及新生儿的生存预后有什么不同?

目前关于妊娠期间诊断为霍奇金淋巴瘤的患者及其新生儿预后结局的研究不足,对霍奇金淋巴瘤产前管理的相关报道也不多。近日,发表在Lancet Haematology的一项回顾性队列研究探讨了妊娠期间诊断为霍奇金淋巴瘤患者产前治疗或产后治疗对孕产妇及其新生儿生存预后的影响。

目前关于妊娠期间诊断为霍奇金淋巴瘤的患者及其新生儿预后结局的研究不足,对霍奇金淋巴瘤产前管理的相关报道也不多。近日,发表在Lancet Haematology的一项回顾性队列研究探讨了妊娠期间诊断为霍奇金淋巴瘤患者产前治疗或产后治疗对孕产妇及其新生儿生存预后的影响。

背景

该研究对在癌症、不孕症和妊娠国际网络数据库(INCIP)中登记的妊娠期霍奇金淋巴瘤患者进行了回顾性队列研究,旨在评估患者的产科结局、产前管理和产妇生存率等情况。

方法

研究人员开展的这项研究为多中心、回顾性队列研究,纳入了INCIP数据库中来自比利时、捷克等17个中心自1969年1月1日至2018年8月1日的134例妊娠期间确诊为霍奇金淋巴瘤的孕妇产科数据。研究人员对3个时期(1995年以前,1995-2004年、2005-2018年)的患者管理进行了分析,将接受产前化疗的患者的产科预后(新生儿出生体重、新生儿是否出现并发症、新生儿是否进入儿童重症监护病房)与未接受产前治疗的患者进行了比较。通过疾病分期评估了孕妇在确诊时的无进展生存(PFS)与总生存(OS),并通过分期与预后评分与3个三级中心数据库中患霍奇金淋巴瘤的非妊娠患者进行了比较。自1997年1月1日起,纳入生存分析的所有患者均接受了标准的阿霉素、博来霉素、长春花碱和达卡巴嗪(ABVD方案)治疗。

结果

在134例妊娠期间确诊为霍奇金淋巴瘤的孕妇中,72 (54%)例患者接受了产前化疗,56(42%)例患者在妊娠期间未接受治疗,6(4%)例患者仅接受了放射治疗。妊娠期间接受化疗的患者人数在过去的数十年中有所增加。对于早产儿的发生率而言,接受化疗的患者(15/69例[22%])和未接受化疗的患者(6/42例[16%])无显着差异;对于儿童重症监护病房入住率而言,两组也未显示出差异(接受产前化疗患者中有19例[29%],未接受产前化疗患者中有12例[35%])。与未接受化疗患者的新生儿相比,接受化疗的患者的新生儿出生体重百分比更低(p=0.035)。另外,对于产科并发症而言,接受产前治疗的患者多于未接受产前治疗的患者(p=0.005),最常见的并发症为早产(9例[12%]vs3例[7%])与胎膜早破(4例[5%]vs0例[0%])。

该研究对77例妊娠患者与211例未妊娠患者进行了匹配对照,分析了孕妇的生存预后。结果显示,患有早期霍奇金淋巴瘤的62例妊娠患者的5年PFS率为82.6%(95%CI:67.4~91.1),142例对照组患者的5年PFS率为88.3%(95%CI:81.6~92.7)(风险比[HR]:1.8;95%CI:0.84~3.87;p=0.130)。妊娠患者的5年OS率为97.3%(95%CI:82.3~99.6),对照组5年OS率为98.4%(95%CI:93.6~99.6)(HR:1.63;95%CI:0.35~7.65;p=0.534)。患有晚期霍奇金淋巴瘤的15例妊娠患者的5年PFS率为90.9%(95%CI:50.8~98.7),69例对照组患者的5年PFS率为74.0%(95%CI:60.9~83.3)(HR:0.36;95%CI:0.04~2.90;p=0.334).妊娠患者的5年OS率为100%(无事件发生),对照组为96.2%(95%CI:85.5~99.1)(HR无法估计;p=0.146)。

结论

与妊娠期间接受治疗的霍奇金淋巴瘤患者相比,接受产前治疗的患者出现早产或胎膜早破的可能性更高。患有霍奇金淋巴瘤的妊娠患者与非妊娠患者的生存无差异,这表明可考虑对部分患者进行产前化疗或推迟至产后治疗并进行定期随访,以保障胎儿的生长。
