SIU-ICUD: Clinical Application of Liquid and Tissue-Based Biomarkers in Prostate Cancer

Several liquid-, and tissue-based markers are available to guide primary diagnosis-, active surveillance-, and treatment-related decision-making for patients with prostate cancer. Most of these tests can improve the balance of harms and benefits associated with early detection, and aid patient selection for treatment intensification. However, the costs of these tests can make their integration in routine clinical practice challenging. To date, prostate-specific antigen (PSA) is still one of the most well-known and widely utilized tumor markers worldwide, with a unique facility ranging from the diagnosis to the treatment-related follow-up of patients with prostate cancer. Future research efforts are needed to integrate biomarkers and novel imaging techniques, such as prostate magnetic resonance imaging, in the decision-making pathways. Despite the growing body of knowledge and evidence, considerable challenges remain in optimizing risk-stratification, improving patient selection and cost-efficacy in different prostate cancer (PCa)-related settings.
