Purpose: Benign Prostatic Hyperplasia (BPH) is an important cause of morbidity for ageing men worldwide. However, the available study limited on natural history BPH and dynamics Prostate-Specific Antigen (PSA) in Sri Lankan population. This aimed to assess relationship between serums Prostate Specific (PSA), prostate volume (PV), PSA density (PSAD) evaluate variations above parameters with agin...
Objective: Prostate cancer is the second common malignancies of men around the world. According to the database about prostate cancer of our institute, in our study, we will analyses prostate cancer patients with Gleason score 10 and investigate its clinical and pathological features. Methods: We retrospectively review 30 prostate cancer patients with complete clinical information in our hospit...
BACKGROUND We aimed to value the usefulness of free to total prostate-specific antigen and Prostate-specific antigen (PSA) density for prostate cancer in the patients with PSA levels of 4.0 ng/ml or less. METHODS A total of 343 subjects with PSA levels of 4.0 ng/ml or less were biopsied. All patients were divided into four groups according to the PSA levels: 0 to 1.0 ng/ml, 1.1 to 2.0 ng/ml, ...
Objective: Serum prostate-specific antigen (PSA) levels are very important in the diagnosis of prostate cancer. Besides prostate cancer, PSA levels can also be increased by cystoscopy, prostate biopsy, prostatitis, and manipulation. There are also studies reporting that ejaculation affects serum PSA levels. In this study, we aimed to investigate the effects of ejaculation frequency on serum PSA...
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...
PURPOSE To predict the malignant potential of prostate cancer (PCa) according to prostate-specific antigen velocity (PSAV), PSA density (PSAD), free/total PSA ratio (%fPSA), and digital rectal examination (DRE). MATERIALS AND METHODS From January 2009 to December 2012, 548 adult male patients were diagnosed with PCa by prostate biopsy at four hospitals in Korea. We retrospectively analyzed 15...
PsaC is the stromal subunit of photosystem I (PSI) which binds the two terminal electron acceptors FA and FB. This subunit resembles 2[4Fe-4S] bacterial ferredoxins but contains two additional sequences: an internal loop and a C-terminal extension. To gain new insights into the function of the internal loop, we used an in vivo degenerate oligonucleotide-directed mutagenesis approach for analysi...
Objective To evaluate the performance of systematic (SBx) and targeted prostate biopsy (TBx) in detecting cancer (PCa) significant (csPCa) including upfront risk stratification with PSA Density (PSAD) a naïve cohort Chinese men. Methods A total 348 men from two medical centers were available for analyses. All underwent mpMRI scan based on an elevated and/or abnormal digital rectal examination (...
Purpose: The purpose of our study was to evaluate the effectiveness of the 12 core biopsy protocol in detecting prostate cancer by comparison with that of the 6 core biopsy according to the prostate-specific antigen (PSA) level and prostate volume. Materials and Methods: Between January 2000 and April 2005, transrectal ultrasound-guided prostate biopsies were performed on 1,100 men suspected of...
