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...

INTRODUCTION The possibilities of PSA (prostate specific antigen) test in screening of prostatic cancer may be evaluated by measuring its sensitivity, specificity and positive predictive value. The majority of reference articles in this field has evaluated the possibility of detection of prostatic cancer by radioimmunoassay (RIA). MATERIAL AND METHODS Prospective study included 2000 male pati...

Chinese men should have a higher prostate-specific antigen (PSA) "gray zone" than the traditional value of 2.5-10.0 ng ml-1 since the incidence of prostate cancer (PCa) in Chinese men is relative low. We hypothesized that PSA density (PSAD) could improve the rate of PCa detection in Chinese men with a PSA higher than the traditional PSA "gray zone." A total of 461 men with a PSA between 2.5 and...

To investigate the appropriate cut-off level of PSA or other clinical parameters at aged ≤ 50 years. The rate of detection of PCa in young men will continue to rise associated with the advancement of the current and evolving practices of screening and detection. In this study, we determined whether to investigate the appropriate cut-off level of PSA or other clinical parameters at aged ≤ 50 yea...

INTRODUCTION The objective of this study was to evaluate the value of serum prostate-specific antigen (PSA) and prostate-specific antigen density (PSAD) in the diagnosis of prostate cancer. MATERIALS AND METHODS A total of 330 consecutive patients suspected of having prostate cancer due to either abnormal digital rectal examination or elevated serum PSA levels underwent transrectal ultrasonog...

background: prostate cancer is the most common malignancy among the male population in the united states and the 3rd most common non-skin cancer among men in iran. its prevalence has shown a rising trend in recent decades. the aim of this study was to report the epidemiological features of prostate cancer in patients referred for prostate biopsy in the south of iran and to evaluate the accuracy...

Abstract Background To find out any association of urethral catheterisation with rise in serum PSA. Methods This study was conducted 80 patients BPH who had to undergo because acute urinary retention. Patients were divided into two groups: Group A (n = 43 patients), age group 40–60 years, and B 47 60–75 years. Values PSA, free/total PSA density recorded both groups before one three days after c...

Objectives The aim of this population-based study was to compare changes in cardiovascular (CV) risk factors over a decade-long period in patients who developed psoriatic arthritis (PsA) and the background population. Methods Patients diagnosed with PsA (n=151) between 1998 and 2008 and matched controls (n=755) who participated in both the Nord-Trøndelag Health Study (HUNT) 2 (1995-1997) and ...

PURPOSE Racial differences exist in the incidence of prostate cancer (PCa). Although many studies have looked at the performance of prostate-specific antigen (PSA) and PSA density (PSAD) in the detection of PCa, only a few have looked at it in relation to Indonesian men. The objective of this study is to find out better PSA and PSAD cutoff point in the detection of PCa in Indonesian men. METH...
