ABSTRACT
Background: Recent reports place prostate cancer as the third most common cause of death from cancer in the worldwide male population. In Mexico it is the principal cause of death from cancer in men and more than 70% of those cases are in advanced stages. Several genetic markers involved in prostate cancer are currently being studied. Manganese superoxide dismutase (Mn-SOD) is associated with cancer, but there are very few studies in the literature analyzing this relation. Therefore, the objective of the present study was to evaluate the existence of alterations in Mn-SOD levels in prostate cancer and benign prostatic hyperplasia.
Materials and methods: Eighty samples, 50% of which corresponded to benign prostatic hyperplasia and 50% to prostate cancer, were obtained. Immunohistochemical diagnostic method was standardized for the detection of Mn-SOD in tissue.
Results: The percentage of Mn-SOD immunoreactive area was 24.83±10.5% in prostate cancer and 14.73±8.7% in benign prostatic hyperplasia.
Conclusions: Mn-SOD expression levels in prostate cancer were significantly higher than those in benign prostatic hyperplasia, suggesting that this gene could be used as a tumor marker in biopsies in patients suspected of presenting with prostate cancer.
