To Study Clinicopathological and Immunohistochemical Expression of Estrogen Receptor, Progesterone Receptor and Her-2/Neu in Prostate Carcinoma
AbstractBackground: Prostate carcinoma is leading cause of cancer related deaths amongst men. This study evaluated expression of ER, PR, HER-2/neu in Prostatic carcinoma and its correlation with Gleason score and other clinical parameters. Methods: 50 histopathologically proven PCa cases were subjected to IHC for ER, PR, HER-2/neu. Result: Most common age group involved was 61-80years. Retention of urine was most frequent complaint. Most prominent Gleason score was (3+4) and group grade was 2. ER expression in tumor epithelial cells was 24% and in stromal cells was 36%. PR expression in stromal cells was 32%. HER-2/neu Cytoplasmic positivity was seen in 6% cases. It was seen that with increase in Gleason grade, ER, PR, HER-2/neu positivity was decreased. Conclusion: ER, PR, HER-2/neu can be used as biomarkers in PCa management.
