Abstract

Background
This study was aimed to evaluate the frequency of estrogen receptors in prostate carcinoma cells in order to better understand the relationship between estrogen receptors in malignant cells and pathology.
Materials and Methods
In this descriptive cross-sectional study, tissue paraffin blocks of patients referred to teaching hospitals of Ahvaz with pathologic diagnosis of prostate adenocarcinoma and benign prostatic hyperplasia were used. Clinical and demographic data of patients were extracted from hospital records. Immunohistochemical staining was performed using Anti ER monoclonal antibody.
Findings
In the present study, 30 prostate tissue specimens including 20 specimens with cancer and 10 specimens with benign hyperplasia were evaluated as control. The mean age of patients was 69.65 years. Estrogen receptor marker was expressed in only 25% of malignant samples. However, 100% of benign samples showed marker expression. ER marker expression was significantly correlated with Gleason score (p = 0.039).
Conclusion
Overall, the findings of this study indicate that the estrogen receptor is decreased in prostate malignancies and is more pronounced in higher grade tumors.
