    Comparative Safety of Filgrastim versus Sargramostim in Patients Receiving Myelosuppressive Chemotherapy
    摘要:
    研究目的:比较在接受骨髓抑制化疗的患者中,预防性使用菲尔格司亭与沙格莫司亭的副作用发生率。 设计:回顾性研究,具有中心交叉设计。 设置:美国十个门诊化疗中心。 患者:490名接受肺癌、乳腺癌、淋巴系统或卵巢肿瘤治疗的患者。 干预:在研究者的判断下,预防性使用菲尔格司亭或沙格莫司亭,剂量由研究者自行决定。 测量与主要结果:评估了副作用的发生频率和严重程度,以及转用替代性粒细胞生长因子的频率。感染引起的发热没有差异。与沙格莫司亭相比,不明原因的发热更为常见(7%对1%,p<0.001),疲劳、腹泻、注射部位反应、其他皮肤病和水肿也更常见(均p<0.05)。骨骼疼痛在使用菲尔格司亭的患者中更为频繁(p=0.06)。接受沙格莫司亭治疗的患者更常转用替代药物(p<0.001)。 结论:与沙格莫司亭相比,使用菲尔格司亭的副作用发生率更低,这表明生活质量和治疗费用也可能存在差异。
