[摘要] 目的 探討膀胱尿路上皮癌組織(BUC)中生存素(Survivin)基因的表達及臨床意義。 方法 選取2010年7月~2018年12月病理科存檔的BUC標本60例,采用En Vision二步法免疫組化檢測Survivin基因的表達。另選取其他手術切下的正常膀胱黏膜標本20例作對照。分析BUC組織與正常膀胱黏膜組織中Survivin基因表達的差異。 結果 60例BUC中Survivin基因的表達陽性43例(71.67%)。20例正常膀胱黏膜組織中Survivin基因表達均為陰性。BUC組織中Survivin基因的表達陽性率較正常膀胱黏膜組織更高(χ2=30.99,P<0.01)。BUC組織中Survivin基因表達與患者的性別和年齡無關(P>0.05),與腫瘤是否復發、浸潤深度和病理分級等密切相關(P<0.05)。結論 BUC組織中Survivin基因的表達存在明顯上升趨勢,Survivin基因的高表達極有可能促進BUC的發生和發展;且其表達與腫瘤的復發情況、惡性程度及病理浸潤深度存在一定的相關性,可能參與BUC病情的轉移和浸潤的過程。

[Abstract] Objective To investigate the expression and clinical significance of survivin gene in bladder urothelial carcinoma (BUC). Methods 60 cases of BUC specimens archived in the pathology department from July 2010 to December 2018 were selected. En Vision two-step immunohistochemistry was used to detect the expression of Survivin gene. Another 20 cases of normal bladder mucosa cut from other operations were selected as controls. The difference of Survivin gene expression between BUC tissue and normal bladder mucosa was analyzed. Results There were 43 cases (71.67%) of positive expression of Survivin gene in 60 cases of BUC. Survivin gene expression was negative in 20 normal bladder mucosa tissues.The positive rate of Survivin gene expression in BUC tissues was higher than that in normal bladder mucosa tissues(χ2=30.99, P<0.01). The expression of Survivin gene in BUC tissues was not related to gender and age of patients (P>0.05), and was closely related to tumor recurrence, depth of invasion and pathological grade(P<0.05). Conclusion The expression of Survivin gene in BUC tissue has a clear upward trend. The high expression of Survivin gene may promote the occurrence and development of BUC. The expression of Survivin gene is related to the recurrence, malignancy degree and depth of pathological invasion, and may be involved in the transfer and invasion of the BUC condition.

總之,BUC組織中Survivin基因的表達存在明顯上升趨勢,Survivin基因的高表達極有可能促進BUC的發生和發展;且其表達與與腫瘤的復發情況、惡性程度以及病理浸潤深度存在一定的相關性,可能參與BUC病情的轉移和浸潤的過程。Survivin基因可作為評估術后復發風險和預后的獨立指標,有望成為Survivin基因診斷及靶向治療的新靶點,通過分子靶向治療手段抑制BUC組織中Survivin基因而促使腫瘤細胞凋亡可能是臨床治療BUC的新途徑。
