BACKGROUND AND OBJECTIVE The literature lacks knowledge about information preferences and decision-making in young prostate cancer patients. This study provides insight into information sources consulted and factors dictating treatment decision-making in young prostate cancer patients. METHODS Subjects were identified from pathology consult service of a(More)
PURPOSE To compare outcomes between patients undergoing surgical and percutaneous cryoablation for treatment of renal masses and identify prognostic variables that determine survival. PATIENTS AND METHODS We retrospectively evaluated the medical records of 194 patients who underwent cryoablation for renal tumors between 1997 and 2008 at a single large(More)
PURPOSE Preservation of renal function is of paramount importance in patients with tumors in solitary kidneys. We compared the renal function and oncologic outcomes of patients treated by partial nephrectomy with those of patients treated by cryoablation for solitary kidney tumors. MATERIALS AND METHODS All patients with solitary kidneys who were treated(More)
PURPOSE Multiparametric magnetic resonance imaging and fusion biopsy detect more high risk prostate cancer and less low risk prostate cancer than systematic biopsy. However, there remains a small subset of patients in whom systematic biopsy captures higher grade disease than fusion biopsy. We sought to identify potential mechanisms of the failure of fusion(More)
INTRODUCTION AND OBJECTIVE Multiparametric magnetic resonance imaging (MRI) and magnetic resonance (MR) -targeted biopsy have a growing role in the screening and evaluation of prostate cancer. We aim to evaluate the current knowledge, attitude, and practice patterns of urologists regarding this new technique. METHODS An anonymous online questionnaire was(More)
Active surveillance has gained popularity as an acceptable management option for men with low-risk prostate cancer. Successful utilization of this strategy can delay or prevent unnecessary interventions - thereby reducing morbidity associated with overtreatment. The usefulness of active surveillance primarily depends on correct identification of patients(More)
MRI-TRUS fusion biopsy (FBx) has proven efficacy in targeting suspicious areas that are traditionally missed by systematic 12-core biopsy (SBx). Midline prostate lesions are undersampled during SBx, as traditional approaches aim laterally during TRUS biopsy. The aim of our study was to determine the utility of FBx for targeting midline lesions identified on(More)
PURPOSE We describe perioperative complications associated with renal cryoablation and identify potential risk factors for certain complications. MATERIALS AND METHODS We retrospectively analyzed the medical records of patients with unifocal renal masses treated with cryosurgery at a single center between 1997 and 2007. All complications associated with(More)
Cryoablation of a solitary tumor mass releases intact tumor antigens and can induce protective antitumor immunity but has limited efficacy in the treatment of established metastatic cancer. Cyclophosphamide (Cy), an anticancer drug, selectively depletes regulatory T cells (T(reg)s) and attenuates suppression of antitumor immunity. We used a BALB/c mouse(More)
PURPOSE Intraoperative frozen section (FS) evaluation for tumor margin during partial nephrectomy (PN) is a matter of controversy in urologic oncology. We evaluated the preferences and practice patterns of urologists regarding intraoperative FS during PN. METHODS A 17-item questionnaire was designed to collect information on surgeons' preferences and(More)
