摘要
目的探讨H-钙黏蛋白表达与结肠癌预后的关系。
方法免疫组织化学检测结肠癌临床样本中H-钙黏蛋白的表达,χ2检验分析计数资料的差异;Kaplan-Meier法绘制生存曲线,Log-rank法对生存分析进行检验;Cox比例风险回归模型分析患者预后的独立影响因素。
结果与癌旁正常组织比较,H-钙黏蛋白在癌组织中表达均降低;H-钙黏蛋白的表达与患者性别、年龄、肿瘤大小、位置等因素之间无明显相关,与肿瘤TNM分期(P=0.003),肿瘤分化程度(P=0.000),淋巴转移(P=0.013)显著相关。Cox分析显示肿瘤TNM分期[风险比(HR)=3.624,95%可信区间(CI):1.875~9.227,P=0.009]、肿瘤分化程度(HR:1.677,95%CI:0.855~3.964,P=0.031)、淋巴转移(HR:6.680,95%CI:3.336~12.028,P=0.003)和H-钙黏蛋白表达(HR:2.927,95%CI:0.998~8.499,P=0.012)是结肠癌患者生存的独立影响因素。Kaplan-Meier生存分析表明,与H-钙黏蛋白表达水平相对较高的患者比较,H-钙黏蛋白表达相对较低的患者预后生存较差(P=0.000)。
结论H-钙黏蛋白是结肠癌患者预后的独立影响因素。
Objective To investigate relationship of H -cadherin expression with the prognosis of colorectal cancer. Methods Expression of H - cadherin in colon cancer tissues and adjacent normal colon tissues were detected by immunohistochemistry (IHC). Difference of variables was analyzed by Chi square test. Survival curve was plotted by Kaplan - Meier method with Log - rank test. Cox proportional hazard re- gression model was used to evaluate the independent prognostic factors. Results Expression of H - cadherin was decreased in colon cancer tissues compared with adjacent normal tissues. H - cadherin expression level in cancer tissues did not correlate with gender, age, tumor size and site. H -cadherin ex- pression statistically significantly correlated with TNM stage ( P = 0. 003 ), tumor differentiation ( P = 0. 000) and lymph nodal metastasis (P = 0. 013). Cox regression analysis indicated that TNM stage [ haz- ard ratio (HR) = 3. 624, 95% confidence interval (CI) : 1. 875 - 9. 227, P = 0. 009 ], tumor differentia- tion (HR: 1. 677, 95% CI: 0. 855 - 3. 964, P =0. 031 ), lymph nodal metastasis (FIR: 6. 680, 95% CI: 3. 336 - 12. 028, P =0. 003) and H - cadherin expression (HR: 2. 927, 95% CI: 0. 998 - 8. 499, P = 0. 012) were the independent prognostic factors of colon cancer patients. Kaplan- Meier survival analysis showed that, compared with patients with relative higher H - eadherin expression, patients with relative lower H - cadherin expression had poorer overall survival ( P = 0. 000). Conclusion H - cadherin is an independent prognostic factor of colon cancer patients.
