[Urinary biomarkers in the diagnosis of prostate cancer.].

INTRODUCTION

The use of prostatespecific antigen (PSA) is useful for the diagnosis ofprostate cancer. Its main limitation is its low specificity,which has led to the search for new biomarkersin order to identify clinically significant prostatecancer and to reduce overdiagnosis and overtreatment.The aim of this article is to summarize the currentliterature on urinary biomarkers used in thediagnosis of prostate cancer.A PubMed-based literature search was conductedup to December 2020. We selected the most recentand relevant original articles, clinical trials and reviewsthat have provided relevant information onthe use of biomarkers.In this review, we have discussed four importanturinary biomarkers useful for prostate cancer diagnosis:PCA3, Select MDX, ExoDX, TMPRSS2:ERG.

CONCLUSION

The use of urinary biomarkers hasimproved of clinically significant prostate cancerdiagnosis. Their use reduces the number of unnecessarybiopsies and avoids overtreatment of indolentprostate cancer.
