Utilization of Biopsy-based Genomic Classifier to Predict Distant Metastasis - Commentary from the Associate Editor of PCAN

Andrew Armstrong

Molecular risk tools are being increasingly utilized in men with localized prostate cancer to help in clinical decision making around the need for surgery or radiation vs. active surveillance, and for the need for salvage radiation after surgery.  The Decipher Genomic Classifier has recently been demonstrated to predict distant metastases in men undergoing radical prostatectomy, using biopsy or surgical tissue, and may provide a greater level of prognostic discrimination than current NCCN or CAPRA risk groups.

Stephen J. Freedland, MD, is director of the Center for Integrated Research in Cancer and Lifestyle and co-director of the Cancer Genetics and Prevention Program and Associate Director for Faculty Development at the Cedars-Sinai Samuel Oschin Comprehensive Cancer Institute. He is also a faculty physician in the Division of Urology within the Department of Surgery at Cedars-Sinai. He has served on numerous American Urological Association guideline panels for prostate cancer and co-chaired a prostate cancer guideline panel for the American Society of Clinical Oncology.

Dr. Freedland's clinical area of expertise focuses on urological diseases, particularly benign prostatic hyperplasia and prostate cancer. His approach toward cancer prevention and awareness focuses on treating the whole patient, not just the disease, by combining traditional Western medicine with complementary holistic interventions. His research interests include investigations on urological diseases and the role of diet, lifestyle and obesity in prostate cancer development and progression, as well as prostate cancer among racial groups and risk stratification for men with prostate cancer.

Meta-analysis of Metabolic Syndrome and Prostate Cancer

Abstract

BACKGROUND: Metabolic syndrome (MetS) and prostate cancer (PCa) are highly prevalent conditions worldwide. Current evidence suggests the emerging hypothesis that MetS could play a role in the development and progression of several neoplasms. The aims of this study are to evaluate the impact of MetS and MetS factors on PCa incidence, on the risk of high-grade PCa and to analyze the role of MetS and single MetS components on the development of aggressive PCa features.

PET imaging of prostate-specific membrane antigen in prostate cancer: current state of the art and future challenges.

BACKGROUND: Prostate-specific membrane antigen (PSMA) is a cell surface enzyme that is highly expressed in prostate cancer (PCa) and is currently being extensively explored as a promising target for molecular imaging in a variety of clinical contexts. Novel antibody and small-molecule PSMA radiotracers labeled with a variety of radionuclides for positron emission tomography (PET) imaging applications have been developed and explored in recent studies.

Androgen deprivation therapy for prostate cancer and dementia risk: a systematic review and meta-analysis

BACKGROUND: Androgen deprivation therapy (ADT) to treat prostate cancer may be associated with an increased risk of dementia, but existing studies have shown conflicting results. Here we synthesize the literature on the association of ADT for the treatment of prostate cancer with dementia risk.

Imaging Response During Therapy with Radium-223 For Castration-Resistant Prostate Cancer With Bone Metastases—Analysis Of An International Multicenter Database

BACKGROUND: The imaging response to radium-223 therapy is at present poorly described. We aimed to describe the imaging response to radium-223 treatment.

METHODS: We retrospectively evaluated the computed tomography (CT) and bone scintigraphy response of metastatic castration-resistant prostate cancer (CRPC) patients treated with radium-223, in eight centers in three countries.

Which, when and why? Rational use of tissue-based molecular testing in localized prostate cancer

Abstract

An increased molecular understanding of localized prostate cancer and the improved ability for molecular testing of pathologic tissue has led to the development of multiple clinical assays. Here we review the relevant molecular biology of localized prostate cancer, currently available tissue-based tests and describe which is best supported for use in various clinical scenarios. Literature regarding testing of human prostate cancer tissue with Ki-67, PTEN (by immunohistochemistry (IHC) or fluroescence in situ hybridization (FISH)), ProMark, Prolaris, OncotypeDX Prostate and Decipher was reviewed to allow for generation of expert opinions.

Increasing incidence of metastatic prostate cancer in the United States (2004–2013).

Abstract
Background:
Changes in prostate cancer screening practices in the United States have led to recent declines in overall incidence, but it is unknown whether relaxed screening has led to changes in the incidence of advanced and metastatic prostate cancer at diagnosis.
