Background: Bladder carcinoma (BC) ranks second among the genitourinary cancers worldwide. Influence of androgens and expression of androgen receptors in neoplasms are recent findings which were implicated in the development of BC. We aimed to study androgen receptor (AR) expression in bladder urothelial neoplasms and correlate its expression with grade and stage of the tumor. Methods: Immunohistochemistry (IHC) was done on samples collected in a tertiary care hospital over one year consisting of 71 urothelial BC and 20 non-neoplastic urothelial conditions. Two pathologists graded the IHC and nuclear staining was considered as positive expression. Results: AR was expressed in 23.9% (17/71) of bladder urothelial neoplasms. AR was expressed in 25.7% and 22.3% of high and low-grade tumors and 25% and 22.3% of non muscle-invasive and muscle-invasive BC. AR expression had no significant correlation with gender, age (> 50 years), muscle invasion or grade. AR expression was significantly absent in non-neoplastic conditions (p = 0.018). Conclusions: AR has varied expression in BC and it is relatively lower in this study population. [ABSTRACT FROM AUTHOR] |
