Prostate cancer (PCa) is a widespread malignancy with global significance, which substantially affects cancer-related mortality. Its spectrum varies widely, from slow-progressing cases to aggressive or even lethal forms. Effective patient stratification into risk groups is crucial to therapeutic decisions and clinical trials. This review examines a wide range of diagnostic and prognostic biomarkers, several of which are integrated into clinical guidelines, such as the PHI, the 4K score, PCA3, Decipher, and Prolaris. It also explores the emergence of novel biomarkers supported by robust preclinical evidence, including urinary miRNAs and isoprostanes. Genetic alterations frequently identified in PCa, including BRCA1/BRCA2, ETS gene fusions, and AR changes, are also discussed, offering insights into risk assessment and precision treatment strategies. By evaluating the latest developments and applications of PCa biomarkers, this review contributes to an enhanced understanding of their role in disease management. [ABSTRACT FROM AUTHOR]

Prostate cancer is a common malignancy in men, but its management is fraught with controversy owing to its variable biologic and clinical behavior. Despite evidence that PSA screening reduces prostate cancer specific metastasis and death, it has not gained acceptance by various health authorities. Nevertheless, recent advances in biomarker development potentially address many of the shortcomings of routine PSA testing alone, including improved specificity for the detection of clinically significant cancer, optimized risk stratification to aid clinical management decisions, and discovery of genetic variants that may guide optimized therapy of advanced disease.
