The Use of Biomarkers in Prostate Cancer Screening and Treatment

Treatment Update

Joseph Renzulli IIAshley V AlfordJoseph M Brito IIIKamlesh K YadavShalini S YadavAshutosh K Tewari

Prostate cancer screening and diagnosis has been guided by prostate-specific antigen levels for the past 25 years, but with the most recent US Preventive Services Task Force screening recommendations, as well as concerns regarding overdiagnosis and overtreatment, a new wave of prostate cancer biomarkers has recently emerged. These assays allow the testing of urine, serum, or prostate tissue for molecular signs of prostate cancer, and provide information regarding both diagnosis and prognosis. In this review, we discuss 12 commercially available biomarker assays approved for the diagnosis and treatment of prostate cancer. The results of clinical validation studies and clinical decision-making studies are presented. This information is designed to assist urologists in making clinical decisions with respect to ordering and interpreting these tests for different patients. There are numerous fluid and biopsy-based genomic tests available for prostate cancer patients that provide the physician and patient with different information about risk of future disease and treatment outcomes. It is important that providers be able to recommend the appropriate test for each individual patient; this decision is based on tissue availability and prognostic information desired. Future studies will continue to emphasize the important role of genomic biomarkers in making individualized treatment decisions for prostate cancer patients.

Vascular Targeted Photodynamic Therapy for Localized Prostate Cancer

Treatment Update

Herbert Lepor

Survival for men diagnosed with prostate cancer directly depends on the stage and grade of the disease at diagnosis. Prostate cancer screening has greatly increased the ability to diagnose small and low-grade cancers that are amenable to cure. However, widespread prostate-specific antigen screening exposes many men with low-risk cancers to unnecessary complications associated with treatment for localized disease without any survival advantage. One challenge for urological surgeons is to develop effective treatment options for low-risk disease that are associated with fewer complications. Minimally invasive ablative treatments for localized prostate cancer are under development and may represent a preferred option for men with low-risk disease who want to balance the risks and benefits of treatment. Vascular targeted photodynamic therapy (VTP) is a novel technique that is being developed for treating prostate cancer. Recent advances in photodynamic therapy have led to the development of photosynthesizers that are retained by the vascular system, which provides the opportunity to selectively ablate the prostate with minimal collateral damage to other structures. The rapid clearance of these new agents negates the need to avoid exposure to sunlight for long periods. Presented herein are the rationale and preliminary data for VTP for localized prostate cancer.
