摘要 目的探讨程序性死亡受体1(PD-1)与程序性死亡受体配体1(PD-L1)在儿童骨肉瘤组织中的表达水平及其临床意义。方法选取2018年1月—2020年1月在医院接受外科手术治疗的24例儿童骨肉瘤患者作为研究对象,收集所有患者临床资料。采用免疫组化法检测瘤组织中的PD-1和PD-L1表达。分析PD-1和PD-L1表达与患者性别、首发症状、肿瘤部位、肿瘤直径、病理类型、TNM分期的相关性。使用Kaplan-Meier方法分析骨肉瘤患者无疾病生存期。结果 PD-1和PD-L1阳性/阴性表达与患者年龄、性别、首发症状、肿瘤部位、肿瘤直径、病理类型、TNM分期无明显相关性(P>0.05)。PD-1阳性/阴性表达的无疾病生存期比较,差异无统计学意义(P=0.618);PD-L1阳性/阴性表达的无疾病生存期比较,差异有统计学意义(P=0.001)。结论 PD-L1的阳性表达与儿童骨肉瘤患者的无疾病生存期(DFS)有关,有助于评估患者预后情况。
