Muscle-invasive bladder cancers (MIBCs) are biologically heterogeneous and have widely variable clinical outcomes and responses to conventional chemotherapy. We discovered three molecular subtypes of MIBC that resembled established molecular subtypes of breast cancer. Basal MIBCs shared biomarkers with basal breast cancers and were characterized by p63(More)
PURPOSE Patients with urothelial cancer with nodal metastasis have a poor prognosis, with many deemed incurable. We report outcomes of a prospective clinical protocol of patients with clinically node-positive disease treated via a multimodality treatment approach. PATIENTS AND METHODS A total of 55 patients with bladder urothelial carcinoma with(More)
Epithelial-to-mesenchymal transition (EMT) has been implicated in the progression of bladder cancer. To study its contribution to bladder cancer metastasis, we established new xenograft models derived from human bladder cancer cell lines utilizing an orthotopic "recycling" technique that allowed us to isolate and examine the primary tumor and its(More)
PURPOSE To our knowledge baseline lithogenic risk factors in the morbidly obese population are currently unknown. Prior studies evaluated known stone formers and correlated risk with increasing body mass index. We describe risk factors for urinary stone formation in a group of unselected morbidly obese patients. MATERIALS AND METHODS Patients scheduled(More)
Cowper's syringocele is a rare but an under-diagnosed cystic dilation of the Cowper's ducts and is increasingly being recognized in the adult population. Recent literature suggests that syringoceles be classified based on the configuration of the duct's orifice to the urethra, either open or closed, as this also allows the clinical presentations of 2(More)
INTRODUCTION The effects of a conditionally replicating adenovirus on various bladder cancer lines were explored, a truncated bone sialoprotein (BSP) promoter controlling the E1a/b lytic-regulating sequence was used, since BSP protein is found in many osteotropic neoplasms, including bladder cancer. METHODS Reverse transcriptase polymerase chain reaction(More)
PURPOSE It is generally believed that carcinoma in situ is refractory to chemotherapy but specific data are lacking to validate this. We evaluated the effect of concomitant clinical carcinoma in situ on cancer specific outcomes after neoadjuvant chemotherapy for muscle invasive bladder cancer. MATERIALS AND METHODS We performed an institutional review(More)
A 9-year-old girl had hypertension (systolic blood pressure of 125 mm Hg) noted at an annual well child visit. An ultrasound study demonstrated a large right renal cystic mass. A partial nephrectomy was performed. The surgical specimen was 9.7 × 9.4 × 6.4 cm and weighed 413.2 g. The tumor stained diffusely positive for smooth muscle actin and focally(More)
OBJECTIVE To compare the results of traditional laparoscopy and a simple, single-docking robotic approach for retroperitoneal lymph node dissection (RPLND), nephroureterectomy, and bladder cuff excision. MATERIALS AND METHODS We evaluated 63 and 37 consecutive patients who underwent laparoscopic and robotic nephrouretectomy with RPLND, respectively, for(More)
Alemtuzumab is a monoclonal antibody targeting CD52 receptors on B and T lymphocytes and is an effective induction agent in pediatric renal transplantation. We report a seven-yr experience using alemtuzumab induction and steroid-free protocol in the pediatric population as safe and effective. Twenty-one pediatric deceased donor renal transplants were(More)
