Abstract:

Background and Objective: Prostate cancer is the second leading cause of death in men. The localized disease often responds to conventional therapies like androgen ablation via castration and/or administration of chemical inhibitors but advanced disease resistant to any curative therapies is still challenge for investigators. There are increasing efforts to enhance the possibility of finding positive and sensitive immune markers for diagnosing and treating prostate cancer. The aim of this study was to investigate the expression patterns of AMACR and iNOS in prostate adenocarcinomas with different histopathologic grade. Methodology: We applied immunohistochemical markers; AMACR and iNOS. Formalin-fixed paraffin embedded tissues of 64 prostate needle biopsy specimens diagnosed as prostate adenocarcinoma between 2005-2010 years were included in the study. Results: AMACR expression were found in 58 (90.6%) and iNOS expression in 54 (84.4%) of 64 prostate adenocarcinomas. No significant relationship of AMACR and iNOS was obtained (p > 0.05). There was no significant correlation of histopathologic grade of the tumors with AMACR and iNOS expression (p > 0.05). Conclusions: The expression of AMACR and iNOS might be important diagnostic immune markers for prostate adenocarcinomas especially in needle biopsies where the quantity and quality of tissue are limited.
