Along with significant advances in prostate cancer biology research, we also observe the rapid development of modern diagnostic tests. New biomarkers are derived to detect disease while it is organ-confined to stratify the risk and to aid clinical decision-making. Majority of these tools have already been validated clinically, but only a few have received premarket clearance and administration approval. Superiority of novel tests is visible not only in improved detection accuracy but predominantly in the assessment of tumour aggressiveness and selection of patients eligible for conservative management. Two factors limiting the clinical implementation of validated biomarker candidates are costs and local availability. For these reasons, currently, their true clinical role starts after routine screening with prostate-specific antigen test. With this review of prostate cancer biomarkers, we attempted to draw general conclusions on clinical perspectives of these novel tools.

Background: Aggressive Variant Prostate Cancers (AVPCs) are incurable malignancies. Platinum-based chemotherapies are used for the palliative treatment of AVPC. The Polycomb Repressive Complex 2 (PRC2) promotes prostate cancer progression histone H3 Lysine 27 tri-methylation (H3K27me3).

Objective: A number of susceptibility genes in prostate tissue have been identified to be associated with prostate cancer (PCa) risk. However, the reported genes based on assessing prostate tissue could not fully explain PCa genetic susceptibility. It is believed that genes functioning in the immune system may fill in the gap of some missing heritability.

Background: Prior studies have concentrated exclusively on how different prostate-specific antigen (PSA) levels affect the prognosis of high-grade prostate cancer (PCa), often overlooking the prognosis of low-grade PCa.
Methods: The present cohort study included individuals diagnosed with PCa from the Surveillance, Epidemiology, and End Results (SEER) database between 2010 and 2021. The all-cause mortality (ACM) and prostate cancer-specific mortality (PCSM) for each treatment group was calculated stratified by the four PSA levels (≤ 4.

Cancer-associated fibroblasts (CAFs) are key stroma cells that play dominant roles in the migration and invasion of several types of cancer through the secretion of inflammatory cytokine IL-17A. This study aims to identify the potential role and regulatory mechanism of CAFs-secreted IL-17A in the migration and invasion of prostate cancer (PC). CAFs and normal fibroblasts (NFs) were obtained from fresh PC and its adjacent normal tissues, respectively.

Materials And Methods: After a shared decision-making process, 128 patients underwent PP for the treatment of localised PCa. Given the subtotal nature of the surgery, patients were informed about the possibility of a detectable prostate-specific antigen and secondary treatment.
