survivin在膀胱癌中的表达及其临床意义

目的：探讨检测尿液中survivin对筛查膀胱癌的作用及组织中survivin表达与临床分期及病理分级的关系。方法：对10例膀胱癌患者（试验一组）晨尿和41例膀胱癌患者（试验二组）术后病理组织，分别以10例非肿瘤疾病患者（对照一组）和7例膀胱良性病变患者（对照二组）作为对照，ELISA法检测尿液中survivin，免疫组化法检测病理组织中survivin，比较试验一组和对照一组尿survivin浓度，分析两试验组尿survivin和膀胱癌组织中survivin相关性。结果：试验一组患者尿survivin浓度与对照一组的差异有显著性意义（P〈0．01）；两试验组患者尿survivin浓度和病理组织survivin免疫标记强度呈正相关（r=0．97，P〈0．01）；试验二组膀胱癌病理标本survivin标记强度与对照二组差异有显著性意义（P〈0．01）；不同分期、不同分级和不同复发时间的膀胱癌患者癌组织survivin标记强度不同（P〈0．05）；膀胱肿瘤临床床特征与组织survivin表达分析提示，肿瘤分期、分级和癌组织survivin表达量是预测患者复发的指标（P〈0．05）。结论：①检测尿survivin很可能是一种敏感性高、特异性强、无创、简便的膀胱癌群体筛查方法和术后随访检查方法。②组织中survivin表达量与膀胱癌分期、分级和复发相关，是预测膀胱癌复发的良好指标。

The expression of survivin in bladder cancer and it''''s clinical significance

Objectives:The screening examination of bladder cancer by detecting urinary survivin and the survivin expression in bladder cancer were evaluated. Methods:Urinary survivin was detected by ELISA and survivn expression of tumor tissue was observed by immunohistochemistry.(Results):There was significant difference in urinary survivin between the groups of treatment and control((P<0.01)) and correlation of survivin in urine and in tumor tissue(r=0.97,P<0.01).There is significant difference in immunostaining density of survivin between cases with different stages,grades and disease-free time among the group of treatment(P<0.05). Conclusion: Detecting urinary survivin is probably a convenient uninvasive test for screening examination of bladder cancer and follow-up examination after treatment.
