[摘要] 目的 通過對人垂體瘤轉化基因1與存活劑在結腸癌組織中的表達的檢測,探討二者與結腸癌生物學行為之間的關系及其機制。 方法 回顧性分析了2007年12月~2011年12月筆者所在醫院診斷為結腸癌的80例患者的臨床資料,采用免疫組織化學法SP法對本組患者結腸癌組織標本中的hPTTG1和survivin蛋白的表達進行檢測。 結果 survivin在結腸癌組織中陽性表達率為82.5%(66/80),但是在正常的結腸黏膜組織中的陽性表達率為5.0%(1/20),差異有顯著的統計學意義(P<0.01)。hPTTG1在結腸癌組織中的陽性表達率為41.3%(33/80),但在正常的結腸黏膜組織中的陽性表達率為85.0%(17/20)。結腸癌組織中,hPTTG1與survivin的表達不存在顯著的相關性(R=0.092, P>0.05)。結論 survivin與hPTTG1在結腸癌組織中具有異常表達的現象,提示了二者在結腸癌的發生以及發展過程中所起的重要作用,可作為結腸癌發生及發展的一個“指示物”。

[Abstract] Objective To detect the expression of human pituitary tumor transforming gene-1 and surviving expression in colon cancer tissue, and study the relationship with colon cancer. Methods 80 cases of patients diagnosed with colon cancer were retrospectively given analysis from December 2007 to December 2011, who stayed in the author's hospital, and used immunohistochemical staining to detect the expression of hPTTG1 and survivin of this group of colon cancer tissue specimens. And then it was analyzed that the relationship between hPTTG1 and survivin expression and colon cancer clinicopathological factors and prognosis. Results Survivin in colon cancer tissue positive expression rate was 82.5% (66/80), but the positive expression in normal colonic mucosa tissue was 5.0% (1/20), both existed statistically significant learning differences (P<0.01); the expression of survivin in colon cancer between gender, age, tumor location, tumor size, type, intestinal wall depth of invasion, histological grade, distant metastasis, Dukes' staging, etc. had no statistical difference (P>0.05). hPTTG1 in colon carcinoma, the positive expression rate was 41.3% (33/80), but it is the positive expression in normal colonic mucosa tissue was 85.0% (17/20), indicating that hPTTG1 in normal colon mucosal tissues, the positive expression rate was significantly higher than the rate of expression in colon cancer tissue, and had a statistically significant difference (P<0.01); the hPTTG1 expression and colon cancer tissue differentiation, Dukes stage and intestinal such as depth of invasion (P<0.05). Colon cancer tissue, hPTTG1 and survivin expression did not exist a significant correlation (R= 0.092, P>0.05). Conclusion Survivin in colon cancer tissue and hPTTG1 with abnormal expression of the phenomenon, which suggests the two played an important role in colon carcinogenesis and the development process. Therefore, both as colon cancer occurrence and development of an indicator.

結腸癌是最為常見的一種消化癌瘤,由于其發病率較高、死亡率大,對人體的健康具有較大的影響。最近研究表明,若要對結腸癌進行準確地診斷,那么就需要對人垂體瘤轉化基因1(human pituitary tumor transforming gene-1,hPTTG1)與存活劑(survivin)在結腸癌組織中的表達進行準確地定位與檢測。本研究主要回顧性分析了2007年12月~2011年12月筆者所在醫院診斷為結腸癌的80例患者的臨床資料,采用免疫組織化學法對hPTTG1與survivin進行檢測、相關性分析等,現將具體的研究過程及結果報道如下。
