background: it is relevant to highlight that there is not a precise and perfect report on either 95 percentile value (upper limit of normal range) or on appropriate reference intervals for serum psa in iranian population. objective: to determine age-specific reference ranges for serum prostate-specific antigen (psa) concentration and psa density (psad) and prostate volumes in a population of he...

we assessed the lower urinary tract symptoms (luts) in prostatic cancer patients and investigated the sensitivity and specificity of international prostate symptom score (ipss) in the screening of these patients. a total number of 132 prostatic cancer patients as the case group who were confirmed by the pathologists and 101 noncancerous men as the control group, aged 50 or older, responded to a...

background prostate is an important male reproductive system gland and its disorders can affect men's quality of life and health. prostatitis, benign prostatic hyperplasia (bph), and prostate adenocarcinoma are major disorders that can be found in all men in different ages. objectives the aim of this study was to investigate the association of diet with serum prostate specific antigen (psa) lev...

background defining the optimal prostate-specific antigen threshold to identify the patients at the highest risk of prostate cancer has always been a controversial issue. objectives this study aims to analyze the diagnostic value of psa and also evaluate the relationship between psa (prostate-specific antigen) and bmi (body mass index) as well as psa and prostate size and volume in asymptomatic...

objective(s): prostate cancer is the world’s leading cause of cancer and the second cause of cancer-related death in men after lung cancer. differentiation of prostate adenocarcinoma from benign prostate lesions and hyperplasia sometimes cannot be done on the basis of morphologic findings. considering the fact that in the prostate adenocarcinoma there is no basal cell layer, basal cell markers ...

despite the high rate of prostate cancer, the incidence of penile metastasis originating from prostate cancer is extremely rare, especially in the form of peyronie’s disease. moreover, brain metastasis, which is caused by prostate cancer, is not a common phenomenon and occurs mostly in older patients. herein, we report a case of a middle-aged man with penile and brain metastasis originating fro...
