To Identify Potential New Urine Markers for the Screening of Prostate Cancer

Summary

Prostate gland is a clinically important male sexual organ and its main function is for the production of semen. Globally, it is the second most common cancer in men globally and is also the fifth cancer cause for death in male. Despite the improvement in the understanding of prostate cancer, the current usage of serum prostate specific antigen (PSA) as a diagnostic marker is still not ideal. Many patients with elevated PSA and then subjected to prostate biopsy were found to have no prostate cancer. Therefore, there is a need to discover new biological markers to improve the current situation in diagnosis and also management of prostate cancer. From the earlier small-scale studies, urinary spermine levels have been shown to correlate well with prostate cancer diagnosis and cancer aggressiveness. Due to its nature, it could provide a more convenient and non-invasive method for detecting prostate cancer. The purpose of this study was to collect urine samples to study the role of potential new urine diagnostic markers (including Spermine and others) for prostate cancer diagnosis.
