The Investigation of New Biological Markers for Prostate Cancer Diagnosis and Management in Chinese Population

Summary

Prostate cancer (PC) is highly prevalent worldwide and is currently the 3rd most commonly diagnosed prostate cancer in Hong Kong male population with more than 1600 new cases diagnosed per year. However, the current use of serum PSA as a diagnostic marker is unsatisfactory. Many patients has elevated serum PSA is actually due to other causes and also the level of serum PSA do not correlate with the staging and grading of prostate cancer. Moreover, the current risk stratification system, based on PSA, clinical staging and Gleason score is of only limited value, as a significant proportion of patients with high-risk nonmetastatic PC have incurable disease due to locally advanced and/or occult metastasis,, whilst others with indolent disease may never suffer morbidity or mortality from PC. Therefore, in order to improve patient management and outcome, there is a need to identify newer markers and also validate some potential markers in Chinese population.
