While now recognized as an aid to predict repeat prostate biopsy outcome, the urinary PCA3 (prostate cancer gene 3) test has also been recently advocated to predict initial biopsy results. The objective is to evaluate the performance of the PCA3 test in predicting results of initial prostate biopsies and to determine whether its incorporation into specific nomograms reinforces its diagnostic va...
PURPOSE Prostate cancer is the most frequent cancer in men in Europe. A major focus in urology is the identification of new biomarkers with improved accuracy in patients with low-risk prostate cancer. Here, we evaluated two-dimensional neovascular complexity in prostate tumor and nontumor biopsy cores by use of a computer-aided image analysis system and assessed the correlations between the res...
PURPOSE We determined clinical factors affecting the under grading of biopsy Gleason sum compared with prostatectomy pathology and developed a model predicting the probability of under grading. MATERIALS AND METHODS We analyzed a cohort of 1,701 patients treated for prostate cancer at our institution between 1988 and 2007 with complete biopsy and pathological data available. Patients with a b...
PURPOSE The accuracy of prostate specific antigen (PSA) to detect prostate cancer has not yet been determined. Autopsy evidence suggests one-third of men have evidence of prostate cancer. Correlation between prostate cancer and sexually transmitted infection is indeterminate. MATERIALS AND METHODS A retrospective database was created of all men who underwent transrectal ultrasound guided pros...
BACKGROUND With the advent of prostate specific antigen the number of patients undergoing prostate biopsy has dramatically increased. The sextant biopsy technique has been conventionally used for the diagnosis of prostate cancer. Recently, concern has arisen that the original sextant method may not include an adequate sample of the prostate, hence it may result in high false negative rates. We ...
PURPOSE Delineating the precise localization of prostate cancer is important in improving the diagnostic accuracy of prostate biopsy. METHODS In Juntendo University Nerima Hospital, initial 12-core or repeat 16-core biopsies were performed using a transrectal ultrasound guided transperineal prostate biopsy method. We step-sectioned prostates from radical prostatectomy specimens at 5-mm interv...
