Plasma cell-free DNA-based predictors of response to abiraterone acetate/prednisone and prognostic factors in metastatic castration-resistant prostate cancer | Prostate Cancer and Prostatic Diseases

Plasma cell-free DNA-based predictors of response to abiraterone acetate/prednisone and prognostic factors in metastatic castration-resistant prostate cancer | Prostate Cancer and Prostatic Diseases : The combination of abiraterone acetate and prednisone (AA/P) is used to treat metastatic prostate cancer, but molecular predictors of treatment response are not well elucidated. We evaluated plasma circulating tumor DNA- (ctDNA-) based copy number alterations (CNAs) to determine treatment-related predictive and prognostic biomarkers for metastatic castration-resistant prostate cancer (mCRPC). Serial plasma specimens were prospectively collected from 88 chemotherapy-naive mCRPC patients before and after 12 weeks of AA/P treatment. Sequencing-based CNA analyses were performed on 174 specimens. We evaluated CNA-associated 12-week responses for primary resistance, time to treatment change (TTTC) for secondary resistance, and overall survival for prognosis (P < 0.05). Associations with prim

Integrated RNA and metabolite profiling of urine liquid biopsies for prostate cancer biomarker discovery | Scientific Reports

Integrated RNA and metabolite profiling of urine liquid biopsies for prostate cancer biomarker discovery | Scientific Reports : Sensitive and specific diagnostic and prognostic biomarkers for prostate cancer (PCa) are urgently needed. Urine samples are a non-invasive means to obtain abundant and readily accessible “liquid biopsies”. Herein we used urine liquid biopsies to identify and characterize a novel group of urine-enriched RNAs and metabolites in patients with PCa and normal individuals with or without benign prostatic disease. Differentially expressed RNAs were identified in urine samples by deep sequencing and metabolites in urine were measured by mass spectrometry. mRNA and metabolite profiles were distinct in patients with benign and malignant disease. Integrated analysis of urinary gene expression and metabolite signatures unveiled an aberrant glutamate metabolism and tricarboxylic acid (TCA) cycle node in prostate cancer-derived cells. Functional validation supported a role

Androgen receptor variant-driven prostate cancer II: advances in laboratory investigations | Prostate Cancer and Prostatic Diseases

Androgen receptor variant-driven prostate cancer II: advances in laboratory investigations | Prostate Cancer and Prostatic Diseases : The androgen receptor (AR) is a key prostate cancer drug target. Suppression of AR signaling mediated by the full-length AR (AR-FL) is the therapeutic goal of all existing AR-directed therapies. AR-targeting agents impart therapeutic benefit, but lead to AR aberrations that underlie disease progression and therapeutic resistance. Among the AR aberrations specific to castration-resistant prostate cancer (CRPC), AR variants (AR-Vs) have emerged as important indicators of disease progression and therapeutic resistance. We conducted a systemic review of the literature focusing on recent laboratory studies on AR-Vs following our last review article published in 2016. Topics ranged from measurement and detection, molecular origin, regulation, genomic function, and preclinical therapeutic targeting of AR-Vs. We provide expert opinions and perspectives on these

PSA Testing and Prostate Cancer Incidence Following the 2012 Update to the U.S. Preventive Services Task Force Prostate Cancer Screening Recommendation: Implications for Racial/Ethnic Disparities | Cancer Epidemiology, Biomarkers & Prevention

PSA Testing and Prostate Cancer Incidence Following the 2012 Update to the U.S. Preventive Services Task Force Prostate Cancer Screening Recommendation: Implications for Racial/Ethnic Disparities | Cancer Epidemiology, Biomarkers & Prevention : The 2012 U.S. Preventive Services Task Force (USPSTF) recommendation against prostate specific antigen (PSA) testing led to a decrease in prostate cancer screening, but its impact on prostate cancer racial/ethnic disparities remains unclear. Methods: The proportion of men ages 40–74 years who received a routine PSA test in the past year was estimated over time in the Behavioral Risk Factor Surveillance System (BRFSS; 2012–2018) and the National Health Interview Survey (NHIS; 2005–2018). Screening trends by race/ethnicity were evaluated using logistic regression models to estimate odds ratios (ORs) of screening adjusting for socioeconomic and healthcare-related factors. Prostate cancer incidence rates and rate ratios (IRRs) by race/ethnicity

Credit...Gracia Lam Jane E. Brody By Jane E. Brody Published Feb. 24, 2020 Updated Feb. 25, 2020 We’ve long been schooled on the lifesaving value of early detection of a potentially deadly cancer. So when a simple blood test was introduced in 1994 that could detect the possible presence of prostate cancer, the second leading cause of cancer deaths among American men, it’s not hard to understand why it quickly became hugely popular. Suddenly, in the decades following approval of the test known as the PSA, for prostate-specific antigen, the number of men receiving a diagnosis of prostate cancer skyrocketed, along with the number undergoing biopsies of this walnut-size gland between

Phase 2 trial of monoamine oxidase inhibitor phenelzine in biochemical recurrent prostate cancer | Prostate Cancer and Prostatic Diseases

Phase 2 trial of monoamine oxidase inhibitor phenelzine in biochemical recurrent prostate cancer | Prostate Cancer and Prostatic Diseases : Monoamine oxidase A (MAOA) influences prostate cancer growth and metastasis in pre-clinical models. We examined effects of phenelzine (a monoamine oxidase inhibitor) in patients with biochemical recurrent castrate-sensitive prostate cancer. An open-label single arm clinical trial enrolled subjects with biochemical recurrent prostate cancer defined by PSA ≥ 0.4 ng/ml (post prostatectomy) or PSA ≥ 2 ng/ml above nadir (post-radiation therapy); no evidence of metastasis on imaging; and normal androgen levels. Subjects received phenelzine 30 mg orally twice daily. Mood symptoms were assessed with the hospital anxiety depression score (HADS) questionnaire. The primary endpoint was the proportion of patients who achieved a PSA decline of ≥50% from baseline. Characteristics of the 20 eligible patients enrolled included: mean ± SD age 66.9 ± 4.8 years and P

Spironolactone use is associated with lower prostate cancer risk: a population-wide case-control study | Prostate Cancer and Prostatic Diseases

Spironolactone use is associated with lower prostate cancer risk: a population-wide case-control study | Prostate Cancer and Prostatic Diseases : Spironolactone, a cheap effective diuretic used to manage hypertension and heart failure, also has anti-androgenic effects through its non-selective binding to steroid receptors, and hence may affect prostate cancer (PCa) risk. This study investigated the association between spironolactone use and PCa risk. For comparison, we also examined associations with thiazide diuretics which do not have anti-androgenic properties. A matched case-control study was undertaken using population-wide data from the Prostate Cancer Data Base Sweden (PCBaSe). All PCa cases diagnosed from 2014 to 2016 were matched by birth year and county with PCa-free controls selected from the general population (1:5). Multivariable conditional logistic regression was used to examine associations between spironolactone use (dose and duration) and PCa risk, and similarly for t
