JCO:利妥昔单抗时代滤泡性淋巴瘤死亡原因:队列汇总分析

2018-11-29 海北 MedSci原创

尽管在利妥昔单抗时代,滤泡性淋巴瘤(FL)患者的预期寿命有所增加,但至今为止,我们对其死亡原因(CODs)还知之甚少。

尽管在利妥昔单抗时代,滤泡性淋巴瘤(FL)患者的预期寿命有所增加,但至今为止,我们对其死亡原因(CODs)还知之甚少。
最近,研究人员汇总了两组新诊断的1-3A级FL患者。患者于2001年至2013年间在两个法国转诊机构(N = 734;中位随访89个月)入组,或于2002年至2012年在爱荷华大学和梅奥诊所卓越研究专业计划(SPORE;N = 920;中位随访84个月)入组。 COD被归类为淋巴瘤,其他恶性肿瘤,治疗相关,或所有其他原因的结果。
结果显示,法国(80%)和美国(77%)队列的十年总生存率相当。研究人员能够对283名死者中的248名(88%)进行COD分类。在整个队列中,淋巴瘤是最常见的COD,10年累计几率为10.3%,其次是治疗相关死亡率(3.0%),其他恶性肿瘤(2.9%),其他原因(2.2%)和未知(3.0%)。
在每个年龄组(包括诊断时≥70岁的患者[25.4%对16.6%]),淋巴瘤或治疗导致的10年累积死亡率高于所有其他原因的死亡率。这针对的是滤泡性淋巴瘤国际预后指数评分为3分至5分的患者(27.4%vs 5.2%),但不针对滤泡性淋巴瘤国际预后指数评分为0到1分的患者(4.0%vs 3.7%)。这是对于在诊断后24个月内未达到无事件生存率的患者(36.1%对7.0%),但对于在诊断后24个月内达到无事件生存率的患者(6.7%对5.7%)则不然。这也是针对有FL转化史的患者(45.9%vs 4.7%),而不是没有的患者(8.1%vs 6.2%)。总体而言,由于淋巴瘤导致的140例死亡中,77例发生在诊断后FL转化的患者中。
因此,尽管利妥昔单抗时代FL患者的总生存期有所改善,但其主要的COD仍然是淋巴瘤,特别是在疾病转化后。与治疗相关的死亡率也是一个问题,这支持对毒性较小的治疗的需求。
