The aim of this study was to evaluate the expression of both markers in UCB using immunohistochemistry.Materials and Methods: Data from 60 patients with UCB were obtained between 2009 and 2018. The samples were divided into four groups based on their smoking history. Group 1 included non-smokers, group 2 smoked < 20 cigarettes/day for 30 years, group 3 smoked for 31– 40 years, and group 4 smoked for > 40 years. Each group then divided into Non muscle invasive bladder cancer (NMIBC) and muscle invasive bladder cancer (MIBC) subgroups. The smear was stained with hematoxylin and eosin (HE) - immunohistochemistry of CD24 and RA, followed by histoscore assessment.Results: The male to female smoking rates was 1.8. Based on gender, in the NMIBC group there were 85.7% men and 14.3% were women while in MIBC 74.4% men and 25.6% women. The mean age of the NMIBC and MIBC groups was 56.3 years and 54.5 years, respectively. There was no significant relationship between smoking status in group 2 (OR 0.31, CI 95% CI, p=0,39), group 3 (OR 013, CI 95% CI, p=0,05), and group 4 (OR 0.23, CI 95% CI, p=0215) to the UCB invasiveness. A significant relationship was observed between cytoplasmic AR expression and UCB invasiveness (OR 0.14[0,04; 0.47], CI 95%, p=0.001). There was no significant relationship between RA in the nucleus and UCB invasion (OR 1.09[0,18; 6.48] CI 95%, p=1000). No significant relationship was observed between CD24 expression and UCB invasiveness (OR 0.81[0,27– 2,45] CI 95%, p=0712).Conclusion: Cytoplasmic AR expression is associated with UCB invasiveness. Smoking history and CD24 expression were not associated with UCB invasion.Keywords: androgen receptor, CD24, immunohistochemistry, smoking, urothelial carcinoma of the bladder
