Abstract

To study the expression of matrix metalloproteinase-2 and-9 in human prostate cancer, matrix metalloproteinase-2 and-9 were immunohistochemically detected in tissues of prostate cancer and benign prostatic hyperplasia (BPH). Our results showed that matrix metalloproteinase-2 and-9 levels in prostate cancer were much higher than those in tissues of BPH, with the cancer invasion being positively correlated with the expression of the metalloproteinases. It is concluded that matrix metalloproteinase-2 and-9 are better molecular markers, which are of help in the diagnosis and prediction of prognosis of prostate cancer.
