Abstract:Objective:To analyze the expressions of EMMPRIN and MMP-7 in human endometrial cancer,and to evaluate the clinical significance of these two markers in the progression of endometrial cancer.Methods: The expressions of EMMPRIN and MMP-7 was examined by immunohistochemistry in all specimens,and the results were statistically analyzed.Results:The positive rates of EMMPRIN and MMP-7 in normal endometrium 、atypical hyperplasia and endometrial carcinoma were 9.09% and 6.82%(4/44 and 3/44)、43.1% and 41.2%(22/51and 21/51)、61% and 59.8%(50/82 and 49/82),respectively,with significant differences found between the latter two groups(P<0.05). EMMPRIN and MMP-7 expressions in endometrial cancer was not correlated with the size of primary tumor or patient ages,ang it was correlated with histological grades and lymphatic metastasis(P<0.05). Spearman rank correlation test analysis showed that the expressions of EMMPRIN and MMP-7 in endometrial cancer was positively correlated with them (r = 0.863, P <0.01). Conclusion:EMMPRIN and MMP-7 may participate in the development ,progression,metastasis of endometrial cancer, may be synergistic in endometrial cancer of the lymph node metastases.
