A 64-year old woman was admitted to the hospital for severe abdominal pain and distension after gardening and chopping wood the day before. She had a medical history of superficial transitional cell carcinoma (TCC) of the urinary bladder and a laparoscopic nefro-ureterectomy for an invasive TCC of the upper urothelial tract in 2012. Clinical examination showed an acute abdomen. Laboratory analysis revealed a plasma creatinine level of 4,23 mg/dl. Computed tomography (CT) imaging of the abdomen showed hypodense free intraperitoneal fluid, suspicious for ascites...

PURPOSE OF REVIEW: Recent Food and Drug Administration (FDA) approval of five new immune checkpoint inhibitors for the treatment of metastatic urothelial cancer represents the first major treatment breakthrough for this disease since the introduction of combination chemotherapy over 30 years ago. This review examines the recent clinical trials leading to FDA approval of these agents, the current challenges facing immunotherapy and areas that require further research. RECENT FINDINGS: The programmed death 1 receptor (PD-1) and its ligand programmed death ligand-1 (PD-L1) are important negative regulators of immune activity, preventing destruction of normal tissues and autoimmunity...

Amyloidosis is a rare disease defined by accumulation of extracellular amyloid systemically or within a specific organ. Localized amyloidosis of the genitourinary system is extremely rare, with the predominate location being the bladder. The imaging findings are often nonspecific and mimic urothelial carcinoma. We present a 49-year-old woman with a chief complaint of flank pain. A filling defect was discovered on radiological imaging. The defect was subsequently biopsied and proven to be a primary amyloidosis of the renal pelvis...

BACKGROUND: Upper tract urothelial carcinoma (UTUC) accounts for approximately 5% of all urothelial cancers. Because of similarities in morphology and histology between UTUC and urothelial carcinoma of the bladder, most treatment guidelines used for UTUC are extrapolated from the urothelial bladder carcinoma setting. With the emergence of new treatment modalities, such as immunotherapy, UTUC-specific prognostic and predictive models are needed. PATIENTS AND METHODS: A retrospective study of 454 UTUC patients who received surgery at Cleveland Clinic (1995-2014) was conducted...

BACKGROUND: We systematically evaluated the prognostic significance of Ki-67 on survival outcomes in patients with upper urinary tract urothelial carcinoma (UTUC) treated with radical nephroureterectomy (RNU). MATERIALS AND METHODS: We searched the Embase, Scopus, and PubMed databases for all articles published up to February 2017 by following the Preferred Reporting Items for Systematic Review and Meta-analyses guidelines. The outcomes of interest included intravesical recurrence (IVR)-free survival, disease-free survival (DFS), cancer-specific survival (CSS), and overall survival (OS)...

PURPOSE: Neoadjuvant chemotherapy is an important adjunct to cystectomy in management of muscle invasive bladder cancer. We investigated factors that predict failure to receive surgery following multi-agent chemotherapy for non-metastatic muscle invasive bladder cancer utilizing the National Cancer Database. MATERIALS AND METHODS: We performed a cohort study including patients diagnosed with cT2-4aN0M0 urothelial cell carcinoma of the bladder between 2004 and 2013 who underwent multi-agent chemotherapy...

INTRODUCTION: Nutritional status has been increasingly recognized as an important predictor of prognosis and surgical outcomes for cancer patients. We evaluated the effect of preoperative malnutrition on the development of surgical complications and mortality after radical nephroureterectomy (RNU) for upper tract urothelial carcinoma (UTUC). MATERIALS AND METHODS: Using data from the American College of Surgeons National Surgical Quality Improvement Program, we evaluated the association of poor nutritional status with 30-day postoperative complications and overall mortality after RNU from 2005 to 2015...

OBJECTIVES: The aim of this study was to clarify the prognostic indicators for upper tract urothelial carcinoma (UTUC) following intravesical bacillus Calmette-Guérin (BCG) therapy for nonmuscle-invasive bladder cancer (NMIBC). METHODS: Data from 402 patients who received intravesical BCG therapy between January 1990 and November 2011 were collected from 10 institutes. The median follow-up interval from transurethral resection of the bladder tumor (TURBT) followed by BCG treatment was 50...

BACKGROUND: The impact of preoperative renal impairment severity on prognosis in urothelial carcinoma remains unelucidated. OBJECTIVE: To evaluate the impact of severe preoperative renal insufficiency on oncological outcomes in patients with urothelial carcinoma who underwent radical cystectomy or nephroureterectomy. DESIGN, SETTING, AND PARTICIPANTS: A total of 1066 patients with urothelial carcinoma who underwent radical cystectomy or nephroureterectomy at six medical centres from February 1995 to November 2017 were retrospectively examined...

Limiting cancer-induced cardiac damage has become an increasingly important issue to improve survival rates and quality of life. Exercise training has been shown to reduce cardiovascular complications in several diseases; however, its therapeutic role against cardiovascular consequences of cancer is in its infancy. In order to add new insights on the potential therapeutic effect of exercise training on cancer-related cardiac dysfunction, we used an animal model of urothelial carcinoma submitted to 13 weeks of treadmill exercise after 20 weeks of exposure to the carcinogenic N-butyl-N-(4-hydroxybutyl)-nitrosamine (BBN)...

BACKGROUND: Radical cystectomy (RC) is delayed in a subset of patients who respond poorly to neoadjuvant chemotherapy (NAC). The present study investigated the clinicopathologic characteristics predicting extravesical disease at RC and the factors associated with NAC tolerability to improve patient selection and the sequence of definitive therapy. MATERIALS AND METHODS: Patients with cT2 urothelial carcinoma of the bladder who underwent NAC were stratified by the final pathologic stage: complete (ypT0N0), partial (≤ pT2), and nonresponse (> pT2 and/or N+)...

OBJECTIVES: To compare complication rates, perioperative outcomes, and survival after radical cystectomy (RC) in patients with prior abdominal and/or pelvic radiation therapy (RT) versus those without an RT history. METHODS: We retrospectively reviewed patients undergoing RC for urothelial carcinoma (UC) between January 2008 and January 2016. Patients were stratified by receipt of RT, and differences in complications (any, minor, and major) at 30 and 90 days, as well as, estimated blood loss, length of surgery, length of hospital stay, and pathologic stage were compared...

Though bladder urothelial carcinoma is the most common form of bladder cancer, advances in its diagnosis and treatment have been modest in the past few decades. To evaluate miRNAs as putative disease markers for bladder urothelial carcinoma, this study develops a process to identify dysregulated miRNAs in cancer patients and potentially stratify patients based on the association of their microRNAome phenotype to genomic alterations. Using RNA sequencing data for 409 patients from the Cancer Genome Atlas, we examined miRNA differential expression between cancer and normal tissues and associated differentially expressed miRNAs with patient survival and clinical variables...

Intravesical BCG therapy after transurethral resection of bladder tumor (TURB) is considered the most effective treatment for prophylaxis against the recurrence of high risk non-muscle invasive bladder cancer, and generally well tolerated and infectious complication are rare. We reported a case of granulomatous prostatitis is a patient who had undergone intravesical BCG therapy due to non-invasive superficial urothelial carcinoma of bladder. This patient was diagnosed by prostate biopsy because of PSA elevation without any other voiding symptoms and abnormal abscess pocket in transrectal ultrasonography...

Urothelial carcinoma of the bladder in childhood is extremely rare. We report on a 12-year-old girl with urothelial carcinoma of the bladder who presented with gross hematuria. Immunohistochemical staining showed normal levels of cytokeratin 20 expression and decreased levels of Ki67 and p53 expression. Human papillomavirus, which can be a cause of urothelial carcinoma of the bladder, was not detected by polymerase chain reaction. We reviewed the literature focusing on diagnostic tools for urothelial carcinoma of the bladder and determined that abdominal ultrasonography, with an extremely high sensitivity of 98%, could be a useful tool for postoperative follow-up in childhood...
