OBJECTIVE We examined the efficacy of an artificial neural network analysis (ANNA) based on parameters available from previously existing examinations for improving the predictive accuracy of prostate cancer screening in the Japanese population. METHODS Two hundred and twenty-eight patients with prostate-specific antigen (PSA) of 2-10 ng/ml were enrolled in this study. Two artificial neural n...
INTRODUCTION The study aimed to explore clinical influence of prostatic stones on lower urinary tract symptoms (LUTS), seminal plasma cytokines, and serum biomarkers. MATERIALS AND METHODS A total of 70 men aged ≤50 years with LUTS divided into 2 groups: group with stones (GSt) and group without prostatic stones (GNoSt). All subjects completed the International Prostate Symptom Score (IPSS) q...
The [-2]proPSA (p2PSA) and its derivatives, the p2PSA-to-free PSA ratio (%p2PSA), and the Prostate Health Index (PHI) have greatly improved discrimination between men with and without prostate cancer (PCa) in prostate biopsies. However, little is known about their performance in cases where a digital rectal examination (DRE) and transrectal ultrasonography (TRUS) are negative. A prospective coh...
We evaluated the expression of the PCA3 gene in urine from patients with nodular hyperplasia/benign prostatic hyperplasia (PNH) or adenocarcinoma type prostate cancer (PCa).The study included 59 men: 22 with PCa, 26 with PNH, and 11 with no alterations (controls). Patients' urine was collected following prostatic massage and quantified by quantitative real-time PCR for prostate cancer antigen 3...
AIM The aim of the study was to compare the yield of mean platelet volume (MPV), total prostate specific antigen (tPSA), free prostate specific antigen (fPSA), f/t PSA ratio and complex prostate specific antigen (cPSA) in patients with prostatitis. MATERIAL AND METHOD The study was designed in the Kayseri Education and Research Hospital. Ninety-six patients with prostatitis were enrolled retr...
We developed a simple one-step dual-label immunoassay for simultaneous measurement of the free, noncomplexed form of prostate-specific antigen (PSA) and total PSA. The assay is based on time-resolved fluorescence and includes a stable fluorescent chelate of Eu to label a monoclonal antibody (mAb) that detects only free PSA, whereas a second mAb labeled with a fluorescent chelate of Tb provides ...
The objective of the study was to evaluate and compare the role of total and free/total ratio of serum prostate specific antigen level in diagnosing carcinoma prostate. A cross sectional study was conducted at the Department of Biochemistry, Dhaka Medical College (DMC) with collaboration of the Department of Urology, Dhaka Medical College Hospital (DMCH), Dhaka from July 2008 to June 2009. This...
PURPOSE To assess the clinical utility of the prostate-specific antigen mass ratio (PSA- MR), a newly developed PSA derivative, simply defined as the (i) PSA density (PSA-D) multiplied by the plasma volume or (ii) total PSA amount in circulation per prostate volume, for predicting prostate cancer (PCa) among men undergoing repeated prostate biopsy (PBx). MATERIALS AND METHODS Patients (n = 28...
Abstract Background The early detection of bone metastases is very important in prostate cancer follow-up. This study aimed to compare conventional tumor markers, namely free prostate-specific antigen (free PSA), total (total PSA/total PSA ratio, alkaline phosphatase (ALP) values, Gleason scores and 99 m Tc-MDP scintigraphy findings the prediction cancer. Methods In total, 175 patients with who...
