Methods: The expressions of Livin and IGF-II were detected by immuno- histochemistry SABC in 60 cases of colorectal cancer and their associated colorectal tissues, and the associations between the expression levels of Livin and IGF-II and clinical pathological characteristics were analyzed. Results: The positive rates of Livin and IGF-II in colorectal carcinomas were 68.33% and 63.33% respectively, higher than those of para-carcinomatous normal tissues and colorectal adenomas. There were no significant correlations between the expressions of Livin, IGF-II in colorectal carcinomas and the patient's age, sex, tumor size and location, while distant metastasis, Dukes stage, histologi- cal type, lymph node metastasis, and whether the tumors have received radiotherapy and chemotherapy were significantly correlated with the expressions of Livin, IGF-II in colorectal carcinomas. Conclusion: Livin and IGF-II play important roles in carcinogenesis and progression of colorectal cancer. This study showed obvious correlation between the expressions of Livin and IGF-II in colorectal cancers. It could be used as the reference for further researches. Livin is hopeful to be a new molecular target in cancer therapy.展开更多
