In the past 10 years, the number of new treatment options for metastatic castration-resistant prostate cancer (mCRPC) has exploded. Prior to 2010, only one agent – docetaxel – had been shown to extend survival for mCRPC patients. Now, a decade later, we have many such agents beyond docetaxel, including abiraterone, enzalutamide, sipuleucel-T, radium-223, and cabazitaxel. In addition, two other agents have shown significant benefits in other disease settings prior to mCRPC – apalutamide and darolutamide. While all extend survival, in the mCRPC setting the added months of life, on average, range from ~2 to 5. Thus, if all the new agents are added together, it is well over a year of added life. However, can the survival months merely be added together? Alternatively, do you get the biggest bang with the first agents and subsequent agents add little? This is an important unanswered question.

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.

Impact of Preoperative Prostate Magnetic Resonance Imaging on the Surgical Management of High-Risk Prostate Cancer - Full Text ArticleObjective - To evaluate the effect of adding multiparametric magnetic resonance imaging (mpMRI) to pre-surgical planning on surgical decision making for the management of high-risk prostate cancer (HRPC).
Patients and methods - A survey was designed to query multiple centers on surgical decisions of 41 consecutive HRPC cases seen from 2012 to 2015. HRPC was defined by the National Comprehensive Cancer Center Network guidelines. Six fellowship-trained urologic oncologists were asked for their surgical plan in regards to the degree of planned nerve-sparing and lymph node dissection.

Androgen Deprivation Therapy for Prostate Cancer and the Risk of Autoimmune Diseases - Full Text ArticleBackground - Androgen deprivation therapy (ADT) has been a mainstay of treatment for advanced prostate cancer (PCa), but limited studies have been performed to investigate the association between ADT and autoimmune diseases.

Performance of PCA3 and TMPRSS2: ERG Urinary Biomarkers in Prediction of Biopsy Outcome in the Canary Prostate Active Surveillance Study (PASS)Background - For men on active surveillance for prostate cancer, biomarkers may improve the prediction of reclassification to a higher grade or volume cancer. This study examined the association of urinary Prostate Cancer Gene 3 (PCA3) and TMPRSS2:ERG (T2:ERG) with biopsy-based reclassification.

The Use of 68Ga-PET/CT PSMA to Determine Patterns of Disease for Biochemically Recurrent Prostate Cancer Following Primary Radiotherapy
Background - 68Ga-PET/CT PSMA scan is being increasingly used for the staging of biochemically recurrent disease. Early identification of recurrent disease after radiotherapy is important in considering suitability for early salvage therapy to improve prognosis. The aim is to identify patterns of suspected prostate cancer recurrence in relation to post-radiotherapy PSA levels, especially below the accepted Phoenix definition of PSA failure (PSA nadir + 2).

A Lifestyle Intervention of Weight Loss via a Low-Carbohydrate Diet Plus Walking to Reduce Metabolic Disturbances Caused by Androgen Deprivation Therapy Among Prostate Cancer Patients: Carbohydrate and Prostate Study 1 (CAPS1) Randomized Controlled TrialPurpose - The objective of this study was to test a low-carbohydrate diet (LCD) plus walking to reduce androgen deprivation therapy (ADT)-induced metabolic disturbances.
Materials and methods - This randomized multi-center trial of prostate cancer (PCa) patients initiating ADT was designed to compare an LCD (≤20g
