PURPOSE The prognostic significance of positive surgical margins in radical prostatectomy specimens was assessed. MATERIALS AND METHODS The interval to progression (increasing prostate specific antigen level) was measured in 478 patients by status of the surgical margins. RESULTS At 5 years, the nonprogression rate was 64% for patients with and 83% for(More)
PURPOSE We assessed the ability of diagnostic tests to distinguish clinically unimportant cancers. MATERIALS AND METHODS We correlated T stage (based on digital examination and ultrasound), prostate specific antigen (PSA), PSA density and pathological features of cancer in systematic biopsy specimens with features of cancer in 170 radical prostatectomy(More)
BACKGROUND The purpose of this study was to determine the ability of clinical tests to predict advanced pathologic stage (seminal vesicle invasion, pT3c, or pelvic lymph node metastases, pN+). METHODS T stage, PSA, PSA density, and pathologic features in systematic biopsy specimens were correlated with pathologic stage in 190 consecutive patients with(More)
