Abstract:
Objective To investigate the expression of survivin, matrix metalloproteinase (MMP-2) and tissue inhibitor 2 of matrix metalloproteinase (TIMP-2) in cervical carcinoma and their relationship with invasion and node metastasis of the cervical cancerous tissues. Methods The expressions of survivin, MMP-2 and TIMP-2 were examined by immunohistochemical S-P method and colour pathological image computer analysis system in 10 cases of normal cervical epithelia, 10 cases of cervical carcinoma in situ, 40 cases of invasive squamous cell cervical carcinoma and 11 cases of invasive cervical adenocarcinoma. The relationship between those indexes and the factors related to clinical pathology of cervical carcinoma were analyzed statistically. Results It was found that the positive level of survivin and MMP-2 expression increased in the order of normal cervical epithelium, cervical carcinoma in situ and invasive carcinoma of cervix (P0.05). The positive expressions of survivin and MMP-2 in patients under 35 years old or with pelvic lymph node metastasis, intravascular involvement and stroma involvement were significantly higher than that in the cases without them, while TIMP-2 expression was opposite to that of MMP-2 (P
