Objective: This study aimed to compare PSMA expression in both prostate cancer and benign prostate disease. Material & Methods: PSMA antigen expression was examined using polymerase chain reaction (PCR), twenty samples from each prostate cancer and benign prostate group were examined at the Department of Pathology Anatomy, Sardjito General Hospital. The data was analyzed using version 21 of SPSS.  Results: The mean PSMA gene expression in benign groups was 13.49 [95% CI: 11.27 – 15.72] and the mean PSMA gene expression in the malignant group was: 25.14 [95% CI: 20.95-29.33], the p-value was <0.01. Using an independent T-test analysis, we found that the increase in PSMA gene expression in the prostate cancer group was statistically significant. Conclusion: The expression of the PSMA gene was correlated with prostate cancer. Increased PSMA gene expression in prostate tissue could be used as a biomarker to diagnose prostate cancer.
