Objectives: To determine the incremental risk of diagnosis of clinically insignificant prostate cancer with serial prostate biopsies.
Methods: We reviewed our institutional radical prostatectomy (RP) database comprising 2411 consecutive patients undergoing RP. We then stratified patients by the prostate biopsy on which their cancer was diagnosed and correlated biopsy number with the risk of clinically insignificant disease and adverse pathology at radical prostatectomy.
Objectives: To evaluate the effect of positive surgical margins in patients with muscle-invasive transitional cell carcinoma of the bladder on survival.
Methods: A retrospective evaluation of a prospectively maintained radical cystectomy database consisting of the data from 344 patients was performed. Cox regression analysis was done, and Kaplan-Meier tables were developed to evaluate the contribution of this finding to clinical outcomes.
Objectives: The natural history of high grade prostatic intraepithelial neoplasia (HGPIN) is incompletely understood limiting evidence based recommendations regarding screening and repeat biopsy intervals. Our objective was to evaluate the natural history of HGPIN to better assess the time frame to disease progression and the pathological findings at the time of progression to cancer.
Methods And Materials: We retrospectively reviewed 74 consecutive patients with an initial diagnosis of HGPIN.
Objectives: The purpose of this study was to assess the prognostic significance of hydronephrosis on pathologic and clinical outcomes in muscle-invasive bladder cancer.
Methods: We performed a retrospective evaluation of a prospectively maintained cystectomy database and identified patients with hydronephrosis on preoperative imaging. Of a total of 306 patients, 57 (19%) had unilateral hydronephrosis and 17 (6%) had bilateral hydronephrosis.
