Additionally, the review addresses key genetic alterations implicated in prostate carcinogenesis, including mutations in BRCA1/2, HOXB13, and PTEN deletions, as well as changes in the androgen receptor pathway. By evaluating recent advancements and applications of these biomarkers, this review aims to enhance understanding of their role in improving early diagnosis, prognosis, and personalised management of prostate cancer.

Clinically implemented assays, including PCA3, ConfirmMDx, and ExoDx Prostate, along with emerging multi-analyte panels, enhance risk stratification, reduce unnecessary biopsies, and guide therapeutic decisions. Integration of epigenetic and liquid biopsy biomarkers into multimodal diagnostic pathways has the potential to support personalized management of prostate cancer; however, many still require further validation and optimization.

Molecular and genetic biomarkers show promise for improving AS by reducing diagnostic misclassification and enhancing prediction of progression. Future research should define clinically relevant cut-offs, clarify integration with MRI, and evaluate longitudinal use. Demonstrating utility in contemporary cohorts could enable the development of biomarker-guided, personalised AS that maintains safety while minimising harm.

This narrative review demonstrates that although PSA remains the mainstay of prostate cancer diagnosis, emerging molecular and genomic biomarkers are enhancing diagnostic specificity, refining risk stratification, and enabling more personalized patient care. The integration of routinely used and novel biomarkers can improve early detection, optimize treatment decisions, and ultimately improve outcomes of prostate cancer patients.

While most exosomal biomarkers remain in early validation phases requiring comprehensive clinical development, the convergence of advancing analytical technologies, evolving regulatory frameworks, and collaborative research initiatives positions exosomes as promising tools for advancing precision medicine in leukemia. However, realistic timelines and sustained investment in methodological standardization remain essential for successful clinical translation.

"MDxHealth SA...today announced the closing of the ExoDx business acquisition from Bio-Techne Corporation, which includes the ExoDx Prostate test...On August 5, 2025, mdxhealth signed a definitive agreement to acquire Exosome Diagnostics, Inc. from Bio-Techne, including the ExoDx Prostate (EPI) test, CLIA-certified clinical laboratory and related assets. Total consideration for the acquisition is $15 million, with $5 million in stock paid at closing and $2.5 million to be paid annually over the following 4 years with 50% in cash and 50% in cash or stock at mdxhealth’s discretion."

Commercially-available, noninvasive biomarker tests consistently outperformed PSA and PSA-based risk calculators for detection of csPCa. Clinical use of these tests appears to substantially reduce the proportion of unnecessary biopsies performed, while maintaining detection of the vast majority of significant cancers.

Prostate cancer biomarkers improve risk stratification and may lower healthcare costs. However, variations in cost-effectiveness, reimbursement policies, and guideline recommendations limit widespread adoption. Prospective studies are needed to validate real-world cost savings and refine biomarker integration into clinical practice. Addressing financial and policy challenges is essential to ensure equitable access and maximize their impact on prostate cancer management.

By assessing genetic mutations (e.g. BRCA1, BRCA2 genes, single nucleotide polymorphism) or the presence of splice variants of the androgen receptor (ARV7), we are able to identify patients in whom the planned treatment may be expected to be ineffective and thus choose other treatment modalities. In the present review article, we offer a comprehensive overview of current diagnostic tests that find application in the diagnosis of early and advanced prostate cancer.

Based on these interim results, the ExoDx TM Prostate Test is valuable both as a standalone tool and when utilized alongside mpMRI to reduce unnecessary procedures and improve management decisions for men on AS. Also, test utilization provides an objective risk assessment and easy access for men considering AS protocols.

Conclusions In conclusion, an EPI test score > 31.47 was more sensitive and specific for biopsy-proven prostate cancer when compared to a PI-RADS score 3 or more. Hence, we may consider using EPI test either as an adjunct to MRI prostate to avoid unnecessary biopsies or in patients with contradication to MRI prostate.
