Purpose: To assess the diagnostic performance of urine telomerase activity (TA) in detecting bladder cancer (BCa) using the modified Telomeric Repeat Amplification Protocol (TRAP) and the Real Time Telomeric Repeat Amplification Protocol with double Polymerase Chain Reaction (RT-TRAP-2PCR).
Methods: In this case-control study, matching urine (in the pre- and post-surgical period) and tissue samples from 68 patients with BCa were assessed for TA. As a control, 45 urine samples were examined from non-BCa patients.
In the Russian Federation, a proportion of bladder cancer in the overall structure of malignant tumors is about 2.8% and among oncological diseases of genitourinary system its incidence is second only to prostate cancer. Bladder cancer ranks as ninth most prevalent in males and as eighteens in females.

Materials And Methods: Evaluation of TA was performed in the urine of 48 patients with bladder cancer (study group) before and after transurethral resection of the bladder wall (n=38), an open resection of the bladder (n=4), and cystectomy (n=6). TA was also evaluated in 48 tumor tissue samples obtained from these patients during removal of the bladder tumor.
Background: Early diagnosis of prostate cancer (CaP) can be addressed by studying prostatic intraepithelial neoplasia (PIN) as precancer (high-grade PIN or HGPIN). This article attempts to analyze the diagnostic role of telomerase as an early marker of carcinogenesis.
Methods: Complex urological patient evaluation and assessment of telomerase activity.
