AIM: To investigate the role of survivin expression in the pathogenesis of colorectal carcinoma. METHODS: Immunohistochemistry S-P method and terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNE) were used to detect the expression of survivin and apoptotic cell in situ in colorectal cancerous tissues, para-cancerous tissues and normal tissues of 48 cases of colorectal carcinoma. RESULTS: The survivin positive unit (PU) was higher in cancerous tissues (38.76±5.14) than in para-cancerous (25.17±7.26) or normal tissues (0.57±0.03) (P〈0.05). The apoptosis index (AI) of para-cancerous tissues was (7.51±2.63%) higher than cancerous tissues (4.65±1.76%). The expression of survivin was associated with pathological grade, lymph node metastasis and Dukes stage of colorectal carcinoma. CONCLUSION: Survivin expression may play an important role in carcinogenesis of colorectal carcinoma and may be associated with malignant biological behaviors of colorectal carcinoma. 展开更多
