BACKGROUND To examine histopathologic features and clinical outcomes of intradiverticular bladder carcinomas. METHODS Twenty-two consecutive patients with intradiverticular bladder carcinoma treated with either endoscopic transurethral resection or partial or radical cystectomy at a single institution between years of 1995 to 2011. Clinicopathologic characteristics and oncologic outcomes of p...

Brain and skin metastasis from urothelial carcinoma of the bladder is rare. There have been few case reports of the clinical course of patients with metastatic urothelial carcinoma of the brain and skin. In the present case, a 60-year-old man had undergone radical cystectomy with an ileal conduit owing to urothelial carcinoma (T1N0M0). The patient developed dizziness 9 years later and a solitar...

Urothelial carcinoma, or transitional cell carcinoma, is the most common urologic malignancy that carries significant morbidity, mortality, recurrence risk and associated health care costs. Despite use of current chemotherapies and immunotherapies, long-term remission in patients with muscle-invasive or metastatic disease remains low, and disease recurrence is common. The molecular chaperone He...

BACKGROUND Nephroureterectomy with bladder cuff excision has been the gold standard surgical treatment for upper tract urothelial carcinoma. In this study, we determined the independent prognostic factors for upper tract urothelial carcinoma. METHODS The records of 285 consecutive patients undergoing nephroureterectomy with bladder cuff excision at our institution between 2003 and 2007 were r...

Urothelial carcinoma is the most common form of bladder cancer, but pathway changes that occur with stage-wise progression have not been well defined. We used a metabolomics approach to identify potential metabolic pathways uniquely altered in normal urothelium, nonmuscle-invasive bladder cancer (NMIBC), and muscle-invasive bladder cancer (MIBC). We performed global metabolomic profiling using ...

Sarcomatoid variant of urothelial carcinoma (SVUC) of the renal pelvis is a rare entity. To the best of our knowledge, around 25 cases of this neoplasm have been reported in the literature to date, most of which were of high stage. The inferior vena cava tumour thrombus, which is a hallmark of renal cell carcinoma (RCC), may rarely be found in urothelial carcinoma of renal pelvis. In this repor...

Purpose: The survival of upper tract urothelial carcinoma has not changed significantly during the last two decades and there were also no adequate prognostic factors for the disease. In this study, we aim to evaluate the predictive value of endothelin expression on the prognosis of patients with upper tract urothelial carcinoma. Methods: One hundred and fifty-six UTUC patients who underwent ra...

Intravenous durvalumab (Imfinzi™; AstraZeneca) is a fully human monoclonal antibody that blocks programmed cell death ligand-1 binding to its receptors (PD-1 and CD80), resulting in enhanced T-cell responses against cancer cells. The US FDA has granted durvalumab accelerated approval for the treatment of patients with locally advanced or metastatic urothelial carcinoma who have disease progress...

INTRODUCTION Sarcomatoid carcinoma of the urinary bladder is a rare bidirectional malignant neoplasm with epithelial and mesenchymal differentiation. The epithelial component is mainly high-grade urothelial carcinoma, and the mesenchymal component includes rhabdomyosarcoma. However, proper differential diagnosis of adult rhabdomyosarcomatous tumors of the bladder can be a challenge. Moreover, l...
