Radical cystoprostatectomy (RCP) followed by bilateral pelvic lymphadenectomy and urinary diversion remains the gold-standard therapy for men with localized muscle-invasive bladder cancer (MIBC). Prostate cancer might be incidentally detected at the time of RCP with a reported prevalence of 24-51%. Typically, these patients are considered to have clinically insignificant disease, but data from emerging series challenge this assumption and suggest that some of these tumours might be aggressive, or somehow increase the aggressiveness of the associated MIBC, and can negatively influence the patient's overall survival outcomes...

PURPOSE: Prior clinical trials evaluating cisplatin for non-muscle invasive bladder cancer (NMIBC) were stopped due to local and systemic toxicity. Currently, there is still a need for improved intravesical therapies, and nanoparticle-based CDDP may be efficacious without the toxicity of free cisplatin observed in the past. EXPERIMENTAL DESIGN: Cisplatin nanoparticles (CDDP NP) were developed using biocompatible poly(L-aspartic acid sodium salt) (PAA), both with and without low and high grafting density of methoxy-polyethylene glycol (PEG)...

Bladder cancer is among the most common and aggressive human malignant carcinomas, thus targeting and removal of bladder cancer cells is still a challenge. Although it is well known that chitosan hydrochloride (CH-HCl) causes desquamation of normal urothelial cells, its effect on cancer urothelial cells has not been recognized yet. In this in vitro study, we analyzed the cytotoxicity of 0.05% CH-HCl on three urothelial models: two cancer urothelial models, i.e. invasive and papillary urothelial neoplasms, and a normal urothelial model...

Bladder cancer (BC) is a major cause of mortality worldwide as it currently lacks fully reliable markers of disease outcome and effective molecular targets for therapy. Mitochondria play a key role in cell metabolism but the role of mitochondrial dysfunctions in BC has been scarcely investigated. In this review, we explored current evidence for the potential role of mitochondrial DNA (mtDNA) alterations (point mutations and copy number) as disease markers in BC. Some germline mtDNA mutations detectable in blood could represent a non-invasive tool to predict the risk of developing BC...

The standard of care for most patients with non-muscle-invasive bladder cancer (NMIBC) is immunotherapy with intravesical Bacillus Calmette-Guérin (BCG), which activates the immune system to recognize and destroy malignant cells and has demonstrated durable clinical benefit. Urologic best-practice guidelines and consensus reports have been developed and strengthened based on data on the timing, dose, and duration of therapy from randomized clinical trials, as well as by critical evaluation of criteria for progression...

BACKGROUND: Radical cystectomy (RC) for muscle-invasive bladder cancer (BCa) has potential for serious complications, prolonged length of stay and readmissions-all of which may increase costs. Although variations in outcomes are well described, less is known about determinants driving variation in costs. OBJECTIVE: To assess surgeon- and hospital-level variations in costs and predictors of high- and low-cost RC. DESIGN, SETTING, AND PARTICIPANTS: Cohort study of 23 173 patients who underwent RC for BCa in 208 hospitals in the USA from 2003 to 2015 in the Premier Healthcare Database...

The objective of this study is to compare cancer risk among different generations of Middle Eastern (ME) immigrants and Non-Hispanic Whites (NHW) in California between 1988 and 2013. We used data from the California Cancer Registry to identify invasive primary incident cancer cases in three population groups: a) first generation ME immigrants, b) second or subsequent generations ME immigrants, and c) NHW. Proportional Incidence Ratio (PIR) was used to compare cancer risk of the 15 selected most common cancers in the 3 population groups taking into consideration time since immigration for first generation ME immigrants...

INTRODUCTION: High-risk non-muscle invasive bladder cancer (HRNMIBC) is a heterogeneous disease that can be difficult to predict. While around 25% of cancers progress to invasion and metastases, the remaining majority of tumours remain within the bladder. It is uncertain whether patients with HRNMIBC are better treated with intravesical maintenance BCG (mBCG) immunotherapy or primary radical cystectomy (RC). A definitive randomised controlled trial (RCT) is needed to compare these two different treatments but may be difficult to recruit to and has not been attempted to date...

BACKGROUND: Bacillus Calmette-Guérin (BCG) is the most effective initial intravesical therapy for high-grade non-muscle invasive bladder cancer, but many patients still fail. Combination intravesical BCG and interferon (IFN) will salvage some patients but results remain suboptimal. OBJECTIVE: We hypothesized that further immunostimulation with intravesical interleukin-2 and subcutaneous granulocyte-macrophage colony-stimulating factor may improve response to intravesical BCG and IFN in patient with prior BCG failure(s)...

The targeting protein for Xenopus kinesin-like protein 2 (TPX2) is associated with the metastasis and prognosis of bladder cancer. p53 is closely related to the progression of bladder cancer. Human glioma pathogenesis-related protein 1 (GLIPR1) is a p53 target gene with antitumor activity. This study aims to explore the interplay between TPX2, p53 and GLIPR1 and its correlation with cell proliferation, invasion and tumor growth in bladder cancer. Here, Western blot and qRT-PCR analysis revealed that TPX2 at both mRNA and protein levels was up-regulated in bladder carcinoma tissues compared to their paired adjacent normal tissues...

INTRODUCTION: There is a multiplicity of treatments currently available for patients with symptomatic refractory urodynamic idiopathic detrusor overactivity (SRU IDO). We have assessed patient treatment preferences and their outcomes over a 12-month period from January 1 2009 to December 31 2009. PATIENTS AND METHODS: A retrospective database of all patients with SRU IDO was reviewed for patient demographics, treatment preference, and outcome. All patients attending for treatment in the time period were offered: no further treatment, repeat bladder training ± antimuscarinic (BT ± AM), acupuncture, intravesical botulinum toxin injection, sacral neuromodulation (SNM), clam cystoplasty ± Mitrofanoff channel formation, and ileal conduit...

Increasing evidences suggest that circular RNAs (circRNAs) exert crucial functions in regulating gene expression. In this study, we perform RNA-seq and identify 6,154 distinct circRNAs from human bladder cancer and normal bladder tissues. We find that hundreds of circRNAs are significantly dysregulated in human bladder cancer tissues. We further show that circHIPK3, also named bladder cancer-related circular RNA-2 (BCRC-2), is significantly down-regulated in bladder cancer tissues and cell lines, and negatively correlates with bladder cancer grade, invasion as well as lymph node metastasis, respectively...
