Clin Genitourin Cancer:叶酸可减少转移性肾细胞癌患者的粘膜炎

2019-08-28 不详 网络

背景:使用靶向疗法治疗转移性肾细胞癌(mRCC)的患者经常会发生粘膜炎。这可能会影响患者的日常生活质量并导致治疗剂量减少,停药或治疗转变。本研究中,我们评估了叶酸减少粘膜炎的效果。患者和方法:根据不良事件通用术语标准4.0版(CTCAE)对发生了≥2级粘膜炎的接受mRCC全身治疗的患者进行了治疗,接受口服叶酸以减少粘膜炎。回顾性地检查了这些患者的医疗记录。结果:共77例患者在接受舒尼替尼(n =

背景:
使用靶向疗法治疗转移性肾细胞癌(mRCC)的患者经常会发生粘膜炎。这可能会影响患者的日常生活质量并导致治疗剂量减少,停药或治疗转变。本研究中,我们评估了叶酸减少粘膜炎的效果。

患者和方法:
根据不良事件通用术语标准4.0版(CTCAE)对发生了≥2级粘膜炎的接受mRCC全身治疗的患者进行了治疗,接受口服叶酸以减少粘膜炎。回顾性地检查了这些患者的医疗记录。

结果:
共77例患者在接受舒尼替尼(n = 29),帕唑帕尼(n = 24),依维莫司(n = 10),阿西替尼(n = 4),西罗莫司(n = 3),白细胞介素-2 /干扰素-α(n = 3),卡博替尼(n = 2),贝伐单抗(n = 1)和纳武单抗(n = 1)治疗期间发生了≥2级粘膜炎。每日给予1至5毫克的叶酸,可显著减少粘膜炎,平均CTCAE等级0.88(95%置信区间[CI],0.74-1.03)VS. 2.38(95%CI,2.26-2.54; P <.0001)。根据治疗分层,叶酸显著降低舒尼替尼(0.97 [95%CI,0.75-1.18] VS. 2.45 [95%CI,2.23-2.67],P <.0001),帕唑帕尼(0.96 [95%CI] ,0.67-1.25] VS.2.20 [2.03-2.38],P <.0001),依维莫司(0.60 [95%CI,0.10-1.10] VS.2.60 [95%CI,2.23-2.97],P <.0001)和其他治疗(0.79 [95%CI,0.38-1.19] VS. 2.36 [95%CI,2.07-2.64],P <.0001)导致的粘膜炎等级。在77名患者中,8名(10%)患者减少了剂量。总体无进展生存期为14个月,总生存期为31个月。

结论:
接受全身治疗的mRCC患者,叶酸可减少治疗导致的粘膜炎。这一发现需要前瞻性研究进行验证。正在进行一项双盲,安慰剂对照的叶酸前瞻性评估(NCT03581773)。
