ABSTRACT Prostate specific antigen (PSA) is a specific marker of prostate tumor which is used for diagnosis of prostate cancer. Apart from prostate cancer,different factors may affect PSA level and ejaculation is one of these possible factors .In a study on 21 patients at ages of 18-37, serum levels of PSA were measured before the ejaculation and about two hours after it. There was no statisti...
Prostate-specific membrane antigen (PSMA) is a type II transmembrane protein, which is anchored in the cell membrane of prostate epithelial cells. It is highly expressed on prostate epithelial cells and strongly up-regulated in prostate cancer. Although, 177Lu-PSMA has been recently introduced for radionuclide therapy of metastatic castration-resistant prostate cancer (mCRPC) with co...
Background and Objective: Non-specific granulomatous prostatitis is an uncommon diffuse inflammatory condition of the prostate. It is important because it may be mistaken for prostatic carcinoma. The aim of the study was to determine the prevalence of non-specific granulomatous prostatitis (NSGP) and comparing the results of transrectal ultrasonography, serum prostate specific antigen (PSA) ...
Background and Objectives: Detection of the biomarkers is one of the effective methods for diagnosis and treatment of prostate cancer. Prostate specific antigen (PSA) is currently the best biomarker available for controlling and detecting this cancer. The purpose of the current study was to design an electrochemical aptamer-based biosensor (electrochemical aptasensor) to measure...
Introduction: Prostatic specific antigen (PSA) is an excellent tumor marker, but it is not specific for prostate cancer. We evaluated the accuracy of PSA adjusted for transition zone volume calculated by transrectal ultrasonography in predicting prostate cancer in men compared with PSA density. Material and Methods: PSA adjusted for transition zone volume was obtained from 100 patients who u...
background: immunoradiometric assay is one of the most common and precise methods for determination of prostate specific antigen (psa) in clinical laboratories. usual use of human serum in routine assays has many disadvantages such as easy contamination and precipitation, instability and unavailability. thus in order to avoid these problems the artificial matrix was used which acts similar to h...
Background: Prostate-Specific Antigen (PSA), also known as gamma-seminoprotein or kallikrein-3 (KLK3), is the best marker for early diagnosis of prostate cancer. Since age and race are affecting PSA levels, determining age-specific reference ranges of PSA in every community is necessary for increasing the efficiency rate of PSA. The aim of the present study was to evaluate the normal distributi...
background and objective: non-specific granulomatous prostatitis is an uncommon diffuse inflammatory condition of the prostate. it is important because it may be mistaken for prostatic carcinoma. the aim of the study was to determine the prevalence of non-specific granulomatous prostatitis (nsgp) and comparing the results of transrectal ultrasonography, serum prostate specific antigen (psa) and...
Background: Prostate cancer is the third leading cause of death and is the most common cause of cancer in elderly men. Regarding to the low accuracy of screening methods such as prostate-specific antigen (PSA), Digital Rectal Examination (DRE) and trans rectal ultrasound (TRUS) in detection and localization of tumor, Magnetic Resonance Imaging (MRI) and Diffusion Weighted Imaging (DWI) attracte...
conclusions results showed that whereas knowledge by itself cannot guarantee men’s participation in prostate cancer screenings, perceived barriers can play an important role in discouraging men from cancer screening participation. therefore, designing programs to address these barriers is very important. results the most common barriers to screening for prostate cancer were a lack of knowledge ...
