摘要 目的探讨89Sr治疗对前列腺癌骨转移患者血清可溶性细胞凋亡相关蛋白(sFas)的影响。方法采用酶联免疫吸附试验(ELISA)和化学发光分析法(CLIA)分别检测46例前列腺癌骨转移患者89Sr治疗前及治疗后30,90和180d血清sFas和PSA水平,并进行相关性分析,同时以30例年龄相匹配的健康者及无骨转移病人作为对照组。结果前列腺癌骨转移患者血清sFas水平(4.48±1.05)ng/ml显著高于无骨转移患者(2.16±0.98)ng/ml(P<0.01);89Sr治疗180d后,前列腺特异抗原(PSA)明显下降,症状缓解,sFas水平(1.85±0.47)ng/ml逐渐下降,但仍高于正常组(1.32±0.41)ng/ml(P<0.05),与无骨转移组无显著差异(te′=-1.562,P>0.05);血清sFas与PSA呈正相关(r=0.628,P<0.01)。结论前列腺癌患者体内存在sFas异常表达,骨转移患者更甚。89Sr能有效降低患者循环血清sFas水平,治疗前后血清sFas的动态变化可能与前列腺癌骨转移发病与转归的病理生理过程有关。
