Eur J Cancer:原发难治性滤泡性淋巴瘤的不良预后和高组织转化率

2021-09-14 Nebula MedSci原创

原发难治性滤泡性淋巴瘤患者的预后较差,而且较高的组织转化率使其本就较差的预后更差了

原发难治性(PREF)滤泡性淋巴瘤(FL)的临床病程与对一线治疗有反应的滤泡性淋巴瘤完全不同。除了对挽救性治疗反应较差之外,原发难治性滤泡性淋巴瘤患者似乎还面临组织转化 (HT) 风险的增加。

Aristotle 财团提供了在一大规模原发难治性滤泡性淋巴瘤病例中调查组织转化风险的机会。Sara等人调查了原发难治性滤泡性淋巴瘤患者相比治疗应答患者或病情稳定患者的组织转化风险及最终结局。

本次分析纳入了 Aristotle 数据库中的 6339 位患者,这些患者是于 1997年至 2013年经组织学确诊的 1级、2 级或 3a 级滤泡性淋巴瘤。主要终点是首次进展或复发时的组织转化的累积发生率(CI),以及转化后的生存预后。

不同组患者的组织转化累积发生率

原发难治性滤泡性淋巴瘤组患者组织转化的 5 年累积发生率为 34%(95% CI 27-43),而经治疗获得部分缓解(PR)或病情稳定(SD)组患者的组织转化的 5 年累积发生率为 7.1%(95% CI 6.0-8.5),获得完全缓解(CR)的患者的该发生率仅有 3.5%(95% CI 3.0-4.2)。

对诱导治疗反应不同的患者复发后的生存率

原发难治性滤泡性淋巴瘤组、PR 组和 SD 组一线治疗后复发后的 5 年存活率分别是 33%(95% CI 28-39)、57%(54-61)和 51%(43-58),初始治疗后获得完全缓解的患者复发后的 5 年存活率为 63%(95% CI 66-72;p<0.001)。

有无发生组织转化的原发难治性滤泡性淋巴瘤患者的生存率

发生了组织转化的原发难治性滤泡性淋巴瘤患者的复发后 5 年存活率为 21%(95% CI 12-31),与没有发生组织转化的原发难治性滤泡性淋巴瘤患者(38%)的相比明显降低(p=0.001)

综上所述,原发难治性滤泡性淋巴瘤患者的预后较差,而且较高的组织转化率使其本就较差的预后更差了
