Characterization of Microbiological and Genetic Features in Prostate Cancer and Their Association with Disease Stage

1. Identify the local inflammatory response in prostate tissue and the systemic response in the blood of patients with prostate cancer, depending on the stage of the disease, and evaluate their prognostic value. 2. Identify the spectrum of microorganisms and antibiotic resistance in patients with prostate cancer prior to prostate biopsy, and assess the risk of complications when using Ciprofloxacin and Fosfomycin. 3. Determine the significance of GAS5, JAZF1, and CTBP2 gene polymorphisms in the development of prostate cancer. 4. Evaluate the association of a specific gene polymorphism with the clinical course of the disease in patients with prostate cancer.

Anti-inflammatory Drugs and Serum Prostate-Specific Antigen Test

Prostate cancer is the most frequently diagnosed cancer in men in the Unites States. Nearly 1 million prostate biopsy procedures are performed in the United States annually and elevated prostate-specific antigen (PSA) level is the primary reason for prostate biopsy in \> 90% of cases. However, at the PSA levels which trigger prostate biopsy, often no cancer is found in prostate biopsy specimens. PSA test can be elevated due to reasons other than cancer such as inflammation or natural variation in the level. Investigators plan to treat men with elevated PSA level with over the counter anti-inflammatory medications (ibuprofen, naproxen) to see if the PSA level will decrease to an acceptable level.
