Purpose: The aim of the study was to identify correlation between DNA damage marker 8-hydroxy 2-deoxy guanosine (8-OHdG) and other prognostic factors such as Gleason's score, serum prostate-specific antigen (PSA), and stage in carcinoma prostate and to assess a probability-correlation between DNA damage and benign prostatic hyperplasia (BPH) and control. Materials and Methods: A study has been carried out prospectively. Forty patients of carcinoma prostate, 34 BPH, and 14 healthy controls were included in the study between the period of July 2010 to July 2012. Serum 8-OHdG level was measured in all subjects as a marker of DNA damage. Results: Serum 8-OHdG level was significantly raised in patient with prostate cancer (313.39 ± 69.48 ng/mL) as compared with BPH patients (204.42 ± 40.97 ng/mL) and control group (198.94 ± 15.74 ng/mL) with P< 0.001. Serum 8-OHdG level in BPH patients was higher than the controls, but the mean difference was statistically insignificant (P = 1.000). The patients with serum PSA >20 ng/mL, Gleason's score >6 had higher mean 8-OHdG levels as compared to serum PSA ≤20 and Gleason score ≤6, as P< 0.05. There was also direct association found between prostate volume and stage of the tumor though it was not significant. Conclusions: These findings suggest that oxidative stress level was significantly raised in prostate cancer patients. It was also observed that a significant direct association exists between oxidative stress and certain clinicopathologic factors, including serum PSA, Gleason score, and metastasis which show that with progression of disease, there was increase in oxidative stress level.
