OBJECTIVE: The aim of this investigation was to study differences between male and female patients with stage T1 urinary bladder cancer (UBC) regarding intravesical instillation therapy, second resection and survival. MATERIALS AND METHODS: This study included all patients with non-metastatic primary T1 UBC reported to the Swedish National Register of Urinary Bladder Cancer (SNRUBC) from 1997 to 2014, excluding those treated with primary cystectomy. Differences between groups were evaluated using chi-squared tests and logistic regression, and survival was investigated using Kaplan-Meier and log-rank tests and Cox proportional hazards analysis...

Objectives: To develop reliable nomograms to estimate individualized overall survival (OS) and cancer specific survival (CSS) for patients with primary small cell carcinoma of the bladder (SCCB) and compare the predictive value with the AJCC stages. Patients and Methods: 582 eligible SCCB patients identified in the Surveillance, Epidemiology, and End Results (SEER) dataset were randomly divided into training (n=482) and validation (n=100) cohorts. Akaike information criterion was used to select the clinically important variables in multivariate Cox models when establishing nomograms...

AIMS: Continent urinary diversion is preferred by some patients and orthotopic urinary diversion (OUD) has become the procedure of choice for most men following cystectomy for invasive bladder cancer. OUD in women, however, is less common, likely due to a high rate of hypercontinence (HC), potentially from lax support of pelvic structures similar to pelvic organ prolapse. As such, we evaluated if abdominal sacrocolpopexy (ASC) at the time of OUD in women led to decreased rates of HC. METHODS: A retrospective review of all female patients receiving OUD by a single surgeon and ASC was performed...

Herein, we elucidated the molecular mechanisms and therapeutic potential of glutathione peroxidase 2 (GPX2) in bladder cancer. GPX2 expression gradually increased during progression from normal to papillary or nodular hyperplasia (PNHP) and urothelial carcinoma (UC) in a rat N-butyl-N-(4-hydroxybutyl) nitrosamine (BBN)-induced bladder carcinogenesis model. GPX2 overexpression was more marked in UC with squamous differentiation (SqD) than in pure UC. Clinical intraepithelial lesions of papillary UC and invasive UC with SqD also had strong GPX2 expression in human radical cystectomy specimens...

BACKGROUND: The mechanistic target of rapamycin (mTOR) has been implicated in driving tumor biology in multiple malignancies, including urothelial carcinoma (UC). We investigate how mTOR and phosphorylated mTOR (pmTOR) protein expression correlate with chemoresponsiveness in the tumor and its microenvironment at final pathologic staging after neoadjuvant chemotherapy (NAC). METHODS: A single-institution retrospective analysis was performed on 62 patients with cT2-4Nany UC undergoing NAC followed by radical cystectomy...

BACKGROUND: The standard treatment for muscle-invasive bladder cancer is radical cystectomy with pelvic lymphadenectomy. Primary organ-preservation by means of multimodal therapy, however, can be a viable alternative to radical surgery. OBJECTIVES: The concept and results of multimodal therapy, consisting of initial transurethral resection of the bladder tumor (TUR-B), followed by simultaneous radiochemotherapy (RCT), are presented. MATERIALS AND METHODS: Evaluation of retrospective cohorts and prospective therapy optimization studies on organ-preservation treatment regimens...

Approximately 1 in 5 new cases of clinically localized bladder cancer is muscle invasive and requires the patient to choose from 1 of 2 prevailing options for treatment: radical cystectomy or radiation to the bladder. However, these treatments are associated with detrimental effects on patient well-being and quality of life, particularly with respect to functional independence, urinary and sexual function, social and emotional health, body image, and psychosocial stress. Compared with the literature on other malignancies like breast or prostate cancer, high-quality studies evaluating the effects of bladder cancer treatment on quality of life are lacking...

Bladder cancer is the sixth leading cancer in the United States. Radical cystectomy is a lifesaving procedure for bladder cancer with or without muscle invasion. Radical cystectomy is performed on 39% of these patients, and 35% will have a life-threatening recurrence. Distant metastases are the most common; local, upper tract, and urethral recurrence can also occur. Surveillance after cystectomy is critical to diagnosing recurrence early. Functional complications after urinary diversion include bowel dysfunction, vitamin B12 deficiency, acidosis, electrolyte abnormalities, osteopenia, nephrolithiasis, urinary tract infections, renal functional decline, and urinary obstruction, which can be reversed when diagnosed early...

Radical cystectomy remains the gold standard therapy for the treatment of muscle-invasive urothelial carcinoma, yet is accompanied by significant rates of perioperative complications and readmission. Enhanced recovery protocols aim to apply evidence-based principles of care to ameliorate the morbidity of this procedure by enabling better tolerance of and recovery from radical cystectomy. Multiple patient series have demonstrated the capacity for enhanced-recovery-after-surgery (ERAS) principles to improve outcomes among patients undergoing radical cystectomy through decreased incidence of gastrointestinal complications and decreased length of hospitalization without increased readmissions or overall morbidity...

Radical cystectomy with bilateral pelvic lymph node dissection is the standard of care for patients with clinically localized muscle-invasive bladder cancer. Survival after radical cystectomy is associated with final pathologic staging. Survival decreases with increasing pT stage because of the presence of occult micrometastases, indicating the need for systemic chemotherapy. Systemic chemotherapy is delivered as either neoadjuvant therapy preoperatively, or as adjuvant therapy postoperatively. This article reviews the evidence for neoadjuvant and adjuvant chemotherapy for the treatment of muscle-invasive bladder and upper tract urothelial cancer and offers recommendations based on these data and recently updated clinical guidelines...

OBJECTIVES: Positive surgical margins (PSM) and lymph node yield (LNY) following radical cystectomy (RC) for urothelial carcinoma of the bladder affect survival. Variations in PSM or LNY at different care facilities are poorly described. We evaluated the relationship between hospital surgical volume and academic hospital status with these surgical outcomes and overall survival (OS). METHODS AND MATERIALS: Patients with nonmetastatic urothelial carcinoma of the bladder who underwent RC were identified from the National Cancer Database (2004-2013)...

OBJECTIVES: To model the cost-effectiveness (CE) of a biomarker-based approach to select patients for neoadjuvant chemotherapy (NAC) prior to radical cystectomy (RC) in muscle-invasive bladder cancer (MIBC). MATERIALS AND METHODS: We obtained most recently clinical studies on locally-advanced bladder cancer treated by RC, including stage distributions, overall survival (OS) estimates, associated costs, and utilization/response to NAC. Additionally, we estimated the putative efficacy of 3 biomarkers to select patients for NAC: DNA repair gene panel [ATM, RB1, and FANCC], ERCC2, and RNA subtypes...

BACKGROUND: Pelvic lymph node dissection (PLND) has a diagnostic and therapeutic role during radical cystectomy in bladder cancer patients. However, at the time, no prospective data supports the value of extended PLND in improving survival expectances. We sought to describe incidence and location of node metastases in patients treated with extended and superextended PLND. METHODS: We evaluated 653 contemporary patients with clinically nonmetastatic high risk nonmuscle invasive or muscle-invasive bladder cancer treated with radical cystectomy and extended or superextended PLND without neoadjuvant chemotherapy at a single tertiary referral center between 1990 and 2013...
