Introduction: Prostate cancer is one of the most common non-cutaneous malignancies in American males. In 2008, it was the sixth leading cause of death from cancer among males. Population-based cancer registries in India show that this has become a growing health concern in many parts of India. There are many interfaces between cancer and chronic kidney disease (CKD).
Materials and methods: Serum levels of urea, creatinine, and uric acid of 50 prostate cancer patients were compared with those of 50 healthy controls, at 95% confidence level taking p < 0.05 as significant. The association of urea, creatinine and uric acid levels with staging, Gleason's scoring and serum prostate-specific antigen (PSA) level was analyzed with the help of appropriate statistical analysis.
Results: Among the three prominent non-protein nitrogenous (NPN) substances used for renal assessment, the levels of urea and uric acid in serum were found to be statistically significantly raised (p < 0.05) in patients with prostate cancer as compared with healthy controls. The serum levels of creatinine were higher in cases as compared with controls but the difference was not found to be statistically significant (p = 0.088). Only uric acid level (p = 0.01) changed significantly among the stage A through stage D. We did not find the statistical significant correlation between the level of urea (r = –0.05, p = 0.75), creatinine (r = –0.24, p = 0.09) and uric acid (r = –0.05, p = 0.75) with PSA.
Conclusion: From our study, it can be concluded that the evaluation of serum levels of urea, creatinine and uric acid may be of utmost diagnostic and prognostic significance in patients with prostate carcinoma.
