Although prostate-specific antigen (PSA) is a very useful screening tool, prostate biopsy is still necessary to confirm prostate cancer (PCA). However, it is reported that PSA is associated with a high false-positive rate and prostate biopsy also has various procedure-related complications. Therefore, the authors have devised a nomogram, which can be used to estimate the risk of PCA, using avai...
Objective To determine the prognostic value of secondary circulating prostate cells (CPCs) in men with pT2 prostate cancer treated with radical prostatectomy. Material and methods Prospective observational study was performed in men with pathologically confined prostate cancer who had been treated with radical prostatectomy. CPCs were obtained by differential gel centrifugation from 8 mL veno...
Prostate cancer (PC), benign prostatic hyperplasia (BPH) and prostatitis are the most common disorders of the prostate gland. Prostate specific antigen (PSA), the marker of prostate cancer has shown reasonable sensitivity but has limited specificity for distinguishing PC from BPH.This study attempts to evaluate the use of uric acid phosphate ratio as a tool in differential diagnosis of prostate...
Early detection of prostate cancer may lead to the overdiagnosis and overtreatment patients as well missing significant cancers. The current diagnostic approach uses elevated serum concentrations prostate-specific antigen (PSA) an indicator risk. However, this test has been widely criticized it shows poor specificity sensitivity. In order improve early diagnosis, several studies have investigat...
Background: Prostate cancer screening is more commonly utilized by highly educated people. As shown by marginalization-related diminished returns (MDRs), the effects of socioeconomic status (SES) such as education on the health outcomes are considerably smaller for ethnic minorities than for Whites. The role of MDRs as a source of ethnic health disparities is, however, still un...
Cervical regional nodal involvement, as the first manifestation of prostatic cancer, has been rarely reported. Prostate cancer metastasis to the supraclavicular lymph nodes with negative immunohistochemical stain of PSA is even rarer. We report a case of prostate cancer with negative immunohistochemical stain of prostate-specific antigen presenting with left supraclavicular node enlargement. A ...
Circulating insulin-like growth factor-I (IGF-I) has been studied extensively in prostate cancer, but there is still little information about IGFs and IGF-binding proteins (IGFBP) in cancers detected by the prostate-specific antigen (PSA) test. Here, we report the findings of a U.K.-based case-control study to investigate circulating IGFs and IGFBPs in PSA-detected prostate cancer with regard t...
PURPOSE MicroRNAs (miRNAs) in biological fluids are potential biomarkers for the diagnosis and assessment of urological diseases such as benign prostatic hyperplasia (BPH) and prostate cancer (PCa). The aim of the study was to identify and validate urinary cell-free miRNAs that can segregate patients with PCa from those with BPH. METHODS In total, 1,052 urine, 150 serum, and 150 prostate tiss...
Background and Objective: Prostate cancer is one of the most common cancers of the urinary system. The most used method for diagnosis is transrectal ultrasonography-guided biopsy. The purpose of this study is a statistical analysis with the aim of reducing unnecessary biopsies based on individual, geographical and genetic patterns in our region. Methods: The medical records of all patients who...
Approximately 30% of patients who underwent radical prostatectomy or radiation therapy will develop biochemical recurrent disease. Biochemical recurrent disease is defined as an increase in the serum value of prostate-specific antigen (PSA) after reaching the nadir. Prostate recurrence can present as PSA-only relapse, local recurrent disease, distant metastases, or a combination of local and di...
