Association between tumor necrosis factor-alpha gene rs1800629 (-308G/A) and rs361525 (-238G> A) polymorphisms and prostate cancer risk in an Iranian cohort.

CONCLUSIONS: Although, the achieved results of this investigation demonstrated that the two examined genetic variants do not seem to be suitable markers for early diagnosis of prostate cancer in this pilot study; however increased risk for the disease is shown in GA heterozygotes and smokers which is indicative of some epigenetic factors influence on prostate cancer etiology.

Authors: Nan LB, Yin XT, Gao JP Abstract BACKGROUND The aim of this study was to investigate the diagnostic value of (F/T)/PSAD for prostate cancer detection in the Chinese population. MATERIAL AND METHODS Data were collected retrospectively from patients with prostate cancer or benign prostatic hyperplasia from July 2009 to September 2014. SPSS 19.0 software was used for the receiver operating characteristic curve (ROC), and calculating sensitivity, specificity, and positive predictive values (PPV) and negative predictive values (NPV), respectively. Comparison of the area under ROC (AUC) was performed using the Me...

The substitution of highly specialized prostate epithelial cells by tumor cells results in dramatic decrease in ACE production in prostate tissues. We performed detailed characterization of ACE status in prostate tissues from patients with benign prostate hyperplasia (BPH) and pro...

AbstractMultiparametric MRI (mpMRI) of the prostate has evolved to be an integral component for the diagnosis, risk stratification, staging, and targeting of prostate cancer. However, anatomic and histologic mimics of prostate cancer on mpMRI exist. Anatomic feature that mimic prostate cancer on mpMRI include anterior fibromuscular stroma, normal central zone, periprostatic venous plexus, and thickened surgical capsule (transition zone pseudocapsule). Benign conditions such as post-biopsy hemorrhage, prostatitis or inflammation, focal prostate atrophy, benign prostatic hyperplasia nodules, and prostatic calcifications can ...

Association between 5α-reductase inhibitors therapy and incidence, cancer-specific mortality, and progression of prostate cancer: evidence from a meta-analysis. Asian J Androl. 2019 Nov 08;: Authors: Luo LM, Yang RD, Wang JM, Zhao SK, Liu YZ, Zhu ZG, Xiang Q, Zhao ZG Abstract 5α-reductase inhibitors (5-ARI) are widely employed for the treatment of benign prostatic hyperplasia. It has been noted that 5-ARI exhibit the potential to attenuate the risk of prostate cancer, but consistent agreement has not been achieved. Moreover, the effect of 5-ARI on cancer-specific mortality and progression ...

Abstract PURPOSE: To investigate the clinical implications of CD3+CD69+ T-cells and CD8+CD28+ T-cells in the peripheral blood of patients prior to radical prostatectomy. MATERIALS AND METHODS: A total of 91 prostate cancer (PCa) patients and 50 benign prostatic hyperplasia (BPH) patients were enrolled from January 2016 to December 2017. The proportions of CD3+CD69+ T-cells and CD8+CD28+ T-cells in the peripheral blood of PCa and BPH patients were detected by flow cytometry, and the association of these T-cell populations with pathological Grade Group and pathological TNM classification was evaluated. Data ana...

Publication date: Available online 15 October 2019Source: The Journal of Steroid Biochemistry and Molecular BiologyAuthor(s): Therina du Toit, Amanda C. SwartAbstractIn clinical approaches to benign prostatic hyperplasia (BPH) and prostate cancer (PCa), steroidogenesis or the disruption thereof is the main thrust in treatments restricting active androgen production. Extensive studies have been undertaken focusing on testosterone and dihydrotestosterone (DHT). However, the adrenal C11-oxy C19 steroid, 11β-hydroxyandrostenedione (11OHA4), also contributes to the active androgen pool in the prostate microenvironment, and...

To the Editor I would like to offer 2 points to expand on the important analysis by Sarkar and colleagues. First, use of a single prostate-specific antigen (PSA) multiplier for all men using 5 α-reductase inhibitors (5-ARIs) is probably not optimal. The goal is to estimate what each man’s PSA would have been in the absence of drug treatment. However, because 5-ARIs inhibit the common age-associated increase in gland volume and PSA, the PSA trajectory for a man being treated with a drug vs his counterfactual trajectory with no drug diverge over time. Furthermore, the benign prostatic hyperplasia component of tot...
