Prostate Cancer Risk by Lipid Parameters

Stephen Freedland
November 08, 2018

Cholesterol is a key building block of cells. It provides crucial support to cell membranes allowing signaling between the inside and outside of cells. Cholesterol makes up ~ 1/3 of the cell membrane. Also, cholesterol is the precursor for many hormones – including testosterone. Without cholesterol, life as we know it could not exist. However, there is such a thing as too much of a good thing. Specifically, high serum cholesterol levels have been linked with numerous conditions such as cardiovascular disease, stroke, and many cancers.

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.

Post Prostatectomy Outcomes of Patients with High-risk Prostate Cancer Treated with Neoadjuvant Androgen Blockade - Full Text Article

Background: Patients with high-risk prostate cancer have an increased likelihood of experiencing a relapse following radical prostatectomy (RP). We previously conducted three neoadjuvant androgen-deprivation therapy (ADT) trials prior to RP in unfavorable intermediate and high-risk disease.

Methods: In this analysis, we report on the post-RP outcomes of a subset of patients enrolled in these studies. We conducted a pooled analysis of patients with available follow-up data treated on three neoadjuvant trials at three institutions. All patients received intense ADT prior to RP. The primary endpoint

Utilization of Biopsy-Based Genomic Classifier to Predict Distant Metastasis after Definitive Radiation and Short-Course ADT - Full Text Article

BACKGROUND: We examined the ability of a biopsy-based 22-marker genomic classifier (GC) to predict for distant metastases after radiation and a median of 6 months of androgen deprivation therapy (ADT). 

METHODS: We studied 100 patients with intermediate-risk (55%) and high-risk (45%) prostate cancer who received definitive radiation plus a median of 6 months of ADT (range 3–39 months) from 2001–2013 at a single center and had available biopsy tissue. Six to ten 4 micron sections of the needle biopsy core with the highest Gleason score and percentage of tumor involvement were

Prostate Cancer Radiation and Urethral Strictures: A Systematic Review and Meta-analysis - Full Text Article

BACKGROUND: We performed a systematic review and meta-analysis to determine the prevalence and predictors of urethral stricture development post radiation therapy (RT) for prostate cancer (PCa). 

METHODS: Published articles in PubMed/Medline, Cochrane, and Embase databases from January 2000 to April 2016 were queried. Inclusion criteria were any study that reported the prevalence of urethral strictures

Saturated Fat Intake and Prostate Cancer Aggressiveness: Results from the Population-based North Carolina-Louisiana Prostate Cancer Project - Full Text Article

BACKGROUND:
Epidemiological and laboratory evidence supports a role for cholesterol in prostate cancer (PC). Dietary saturated fat content impacts serum cholesterol levels. However, epidemiological associations between saturated fat and PC aggressiveness are inconsistent. We hypothesized that high saturated fat intake would be associated with increased PC aggressiveness, and that statin use would modify this association.

Is Active Surveillance a Suitable Option for African American Men with Prostate Cancer? A Systemic Literature Review - Full Text Article

Background: Certain patients presenting with either low or very-low-risk prostate cancer (PCa) can represent a therapeutic dilemma for physicians. The oncologic outcomes of active surveillance (AS) for men with very-low-risk PCa are overall excellent.  However, there are concerns about AS related to the potential for upgrading or upstaging. The African American (AA) population is under-represented in studies evaluating AS outcomes and this is particularly important because of the unique epidemiology of PCa in AA men.

Radiographic Progression with Non Rising PSA in mCRPC: PREVAIL: PCAN Full Text Article

BACKGROUND: Advanced prostate cancer is a phenotypically diverse disease that evolves through multiple clinical courses. PSA level is the most widely used parameter for disease monitoring, but it has well-recognized limitations. Unlike in clinical trials, in practice, clinicians may rely on PSA monitoring alone to determine disease status on therapy. This approach has not been adequately tested. 

METHODS: Chemotherapy-naive asymptomatic or mildly symptomatic men (n = 872) with metastatic castration-resistant prostate cancer (mCRPC) who were treated with the androgen receptor inhibitor enzalutamide in the PREVAIL study were analyzed post hoc for rising versus nonrising PSA (empirically defined as 41.05 vs ⩽ 1.05 times the PSA level from 3 months earlier) at the time of radiographic progression. Clinical characteristics and disease outcomes were compared between the rising and nonrising PSA groups.
