【摘要】 目的 观察宫颈癌患者血清可溶性Apo1/Fas(sApo1/Fas)水平变化及其临床意义。方法 应用酶联免疫吸附试验法(ELISA)对30例正常人及60例宫颈癌患者的血清sApo1/Fas水平进行检测,并比较20例宫颈癌患者根治术前后血清sApo1/Fas水平。结果 Ⅰ、Ⅱ、Ⅲ、Ⅳ期宫颈癌患者的血清sApo1/Fas水平均明显高于正常对照组(P<0.01);Ⅳ期宫颈癌患者的血清sApo1/Fas水平明显高于其他各期,Ⅲ期明显高于Ⅱ期,Ⅱ期又明显高于Ⅰ期,差异均有统计学意义(P<0.01);宫颈癌患者根治术后的血清sApo1/Fas水平明显低于术前(P<0.01)。结论 动态检测血清sApo1/Fas水平可能对判断宫颈癌病情和预后有一定程度的参考意义。

Abstract: Objective To study the serum level of soluble Apo1/Fas (sApo1/Fas)and its clinical significance in patients with cervical cancer.Methods Serum content of sApo1/Fas in 30 normal controls and 60 cervical cancer patients was determined by ELISA.Results Serum level of sApo1/Fas in patients with cervical cancer was significantly higher than that in normal controls (P<0.01), and its content increased gradually with the upgrading of tumor stage and decreased remarkably after radical surgery (P<0.01).Conclusion Detection of serum sApo1/Fas level may be helpful for evaluating the patient s condition and prognosis in patients with cervical cancer.

众多的研究表明,肿瘤的发生、发展及预后与凋亡密切相关。Apo1/Fas(CD95)是一种Ⅰ型跨膜蛋白,属于肿瘤坏死因子受体家族(TNFR)及神经生长因子受体家族(NGFR)[12], Apo1/FasL 或某些Apo1/Fas的单抗与Apo1/Fas结合后,可触发Apo1/Fas所在靶细胞在数小时内凋亡[3]。Apo1/Fas受体配体系统在哺乳类动物体内有许多重要生理功能,而且与多种免疫性疾病、血液系统疾病和肿瘤的发生有关。Apo1/Fas受体有两种形式:膜型Apo1/Fas(mApo1/Fas)和可溶性Apo1/Fas(sApo1/Fas)。细胞表面的mApo1/Fas通过与Apo1/FasL结合而激发Apo1/Fas阳性细胞凋亡,sApo1/Fas通过与Apo1/FasL竞争结合而抑制mApo1/Fas途径介导的细胞凋亡,因此可以认为sApo1/Fas与肿瘤细胞逃避免疫监视以及恶性肿瘤的演变有关。为评价sApo1/Fas对宫颈癌病情的判断、手术效果及预后的价值,我们对60例不同病期、不同年龄、不同病理类型宫颈癌患者的sApo1/Fas水平作了测定,并比较20例宫颈癌患者根治手术前后sApo1/Fas水平,现将结果报道如下。
