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 (TUNEL) 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.
