RESUMEN
Objective: Our purpose was to study the expression of protein of nm23 gene in patients with epithelial ovarian carcinoma.Methods:Protein of nm23 gene was detected by immunohistochemical technique in 45 patients with epithelial ovarian cancer, 12 with borderline, and 10 with benign ovarian tumor.Results:The positive expression rate in ovarian cancer (73.3%) was significantly higher than that of the benign and borderline tumors. There was no significant correlation between the expression of nm23 gene and the histological type, grade, the existence of ascites or the size of residul after operation. However, the expression of nm23 gene protein was negatively related with the FIGO stage. The overall survival rate of the patients with positive expression of nm23 gene was much higher than that of the patients with negative expression. Conclusion:The findings suggest that nm23 gene protein might serve as a valuable and independent marker for the prognosis of ovarian cancer.
RESUMEN
Objective To study the express of matrix metalloproteinase(MMP)-2 and tissue inhibitor of metalloproteinase(TIMP)-2 protein in human endometrial carcinoma. Methods The Immunohistochemistry was used to measure the MMP-2, TIMP-2 in endometrial carcinoma tissue of 40 patients, the atypical hyperplasia of 12 samples and the normal endometrium of 12 samples. Results The positive express of MMP-2 and TIMP-2 in the normal endometrium , atypical hyperplasia and endometrial carcinoma was increased gradually. In endometrial carcinoma, with progression of clinical stage and decrease of histological grade as well as deepening of cancer invasion, the ratio of MMP-2/TIMP-2 was increased. Conclusions The expression of MMP-2 and TIMP-2 were connected with endometrial carcinoma. The imbalance of MMP-2/TIMP-2 in the endometrial cancer might be one of the pathogenesis and development.
