摘要 目的:观察端粒酶和视网膜母细胞瘤基因蛋白(pRb)在结直肠癌中的表达,并探讨它们之间的相关性。方法:应用免疫组化法检测48例结直肠癌组织中端粒酶和pRb的表达,并用统计学方法分析表达结果与结直肠癌临床病理因素间的关系。结果:结直肠癌中端粒酶和pRb的阳性表达率分别为87.5%和56.3%,且与结直肠癌区域淋巴结转移和临床分期关系密切(P〈0.05),端粒酶表达还与组织病理学分级密切相关(P〈0.05)。结论:检测结直肠癌组织中端粒酶和pRb的表达有助于结直肠癌患者的预后评估,结直肠癌组织中端粒酶与pRb表达呈显著负相关关系,两者可能从不同方面共同促进结直肠癌的发生。 Objective:To investigate the expression of telomerase and pRb in colorectal cancer and explore the correlation between them. Methods:The immunohistochemistry method was used to detect the expression of telomerase and pRb in 48 specimens of colorectal cancer. The findings was analyzed by a statistical method, and compared with the clinicopathologic factors of colorectal carcinoma, and then to explore the relationship between them. Results:The positive expression rates of telomerase and pRb in colorectal cancer were 87.5% and 56.3%, respectively, which closely related to the lymph node metastasis and clinical stages of colorectal cancer(P 〈 0.05), furthermore, the expressive level of telomerase was positively correlated with the histopathological grading. Conclusions:Detecting the expression of telomerase and pRb protein may be helpful to evaluate the prognosis of colorectal cancer. The expression of telomerase was negatively correlated with the expression of pRb ( P 〈 0.05 ) protein. It suggests that telomerase and pRb protein may promote the carcinogenesis from various aspects.
