survivin、VEGF及Ki67在结直肠癌中的表达及其临床意义

Expression and Clinical Significance of survivin 、VEGF and Ki67 in Colorectal Carcinoma

  • 摘要: 目的 探讨结直肠癌组织中存活素(survivin)、血管内皮生长因子(VEGF)、细胞核增殖相关抗原Ki67的表达与各临床病理因素的关系,评价survivin、VEGF及Ki67在结直肠癌预后判断中的价值。方法 采用免疫组织化学PowerVision两步法检测40例结直肠癌组织中survivin、VEGF及Ki67的表达情况,回顾性分析survivin、VEGF及Ki67与各临床病理因素及预后之间的关系。结果 survivin、VEGF及Ki67在结直肠癌组织中的表达阳性率均明显高于癌旁正常组织(P〈0.01),与Duke's分期及淋巴结转移有明显相关(P〈0.05),Duke's C期、D期结直肠癌组织明显高于Duke's A期、B期,有淋巴结转移组survivin、VEGF及Ki67阳性率明显高于无淋巴结转移组。survivin、VEGF及Ki67阳性表达患者3、5年生存率明显低于表达阴性者(P〈0.05)。结论 在结直肠癌发生、发展过程中伴随着survivin、VEGF及Ki67的表达,检测结直肠癌组织survivin、VEGF及Ki67可能对判断结直肠癌的淋巴结转移及病情进展有一定的价值。survivin、VEGF及Ki67阳性的患者3年、5年生存率明显降低,对三者进行检测,可以对结直肠癌患者的预后评估有一定的辅助意义。

     

    Abstract: Objective  To investigate the relationship between the expression of survivin、VEGF、Ki67 and the clinicopathologic parameters in colorectal carcinoma (CRC), and evaluate their significances in predicating the prognosis. Methods  Immunohistochemical method by two2step Power Vision was used to detect survivin、VEGF、Ki67 expression in 40 patient s with CRC. The relationship between the expression of survivin、VEGF、Ki67 and the clinicopathologic parameters, prognosis was ret rospectively analyzed. Results  The positive rates of survivin、VEGF、Ki67 in CRC were all higher than those in matched normal tissues ( P < 0. 01) . Their expressions were related to Duke' s stages and the metastasis of lymph nodes. The expression rates of the three markers in CRC with the metastasis of lymph nodes were higher than those without metastasis ( P < 0. 05), and higher in Duke' s C、D stages than in Duke' s A、B stages ( P <0. 05) . survival rate of 3 years and 5 years were lower in those patient s with the positive expression of these markers than in those with the negative expression ( P < 0. 05) . Conclusion  The expression of survivin、VEGF、Ki67 were associated with the development and metastasis of CRC. The patient s with expressions of survivin、VEGF、Ki67 have lower survival rates of 3 years and 5 years. We may evaluate the prognosis of CRC through the test of survivin、VEGF and Ki67.
