There are emerging data on novel tumor markers such as matrix metalloproteinase-2 (MMP-2 or gelatinase-A), which play a key role in tissue invasion and metastasis. We designed an investigation to assess the usefulness of MMP-2 activity as compared to prostate specific antigen (PSA) in cancer staging process. We have analyzed the circulating form of MMP-2 in serum samples of patients suffering f...

background: the normal prostate-specific antigen (psa) level in patients with urethral catheterization is a controversy. we designed this study to investigate the effect of nontraumatic urethral catheterization without urinary retention on serum psa. materials and methods: seventy patients scheduled for urethral catheterization before elective surgeries were randomly selected and included in th...

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...

This article describes markers used for prostate biopsy decisions, including prostrate-specific antigen (PSA), free PSA, the prostate health index, 4Kscore, PCA3, and ConfirmMDx. It also summarizes the use of nomograms combining multiple variables for prostate cancer detection.

A 64-year-old man with a prostate-specific antigen (PSA) of 5·74 ng/mL, no lower urinary symptoms, and family history prostate cancer presented at our clinic University College London Hospital (London, UK) in April, 2018. Axial T2-weighted MRI the showed multicystic lesion (PSA density 0·07 ng/mL/mL), MRI-targeted biopsies Gleason 3 + adenocarcinoma (Gleason Grade Group 1) prostatic intraepithe...

Background: Due to its biological properties, Prostate-specific membrane antigen (PSMA) is a good target for prostate cancer molecular imaging. The aim of this work was evaluate the role 18F PSMA Tomography–Computed Tomography (PET CT) in diagnosis and staging association with specific serum level. Methods: This prospective cohort performed on 30 individuals pathologically proven patients, seve...

objective(s): the aim of this study was to analyze detection rates and effectiveness of 18f-fluorodeoxyglucose positron emission tomography (fdg-pet) cancer screening program for prostate cancer in japan, which is defined as a cancer-screening program for subjects without known cancer. it contains fdg-pet aimed at detection of cancer at an early stage with or without additional screening tests ...
