BACKGROUND: The current study was performed to examine temporal trends and compare overall survival (OS) in patients undergoing radical cystectomy (RC) or bladder-preservation therapy (BPT) for muscle-invasive urothelial carcinoma of the bladder. METHODS: The authors reviewed the National Cancer Data Base to identify patients with AJCC stage II to III urothelial carcinoma of the bladder from 2004 through 2013. Patients receiving BPT were stratified as having received any external-beam radiotherapy (any XRT), definitive XRT (50-80 grays), and definitive XRT with chemotherapy (CRT)...

BACKGROUND: Neoadjuvant chemotherapy in pure urothelial bladder cancer provides a significant survival benefit. However, to the authors' knowledge, it is unknown whether this benefit persists in histological variants. The objective of the current study was to assess the effect of neoadjuvant chemotherapy on the probability of non-organ-confined disease and overall survival after radical cystectomy (RC) in patients with histological variants. METHODS: Querying the National Cancer Data Base, the authors identified 2018 patients with histological variants who were undergoing RC for bladder cancer between 2003 and 2012...

REVIEW
Manmeet Saluja, Peter Gilling
Intravesical bacillus Calmette-Guérin has been the standard of care for high-risk non-muscle-invasive bladder cancer for 40 years. It remains one of the most successful immunotherapies ever used. Bacillus Calmette-Guérin shows superior efficacy to alternative intravesical treatments, and has an established role in reducing both recurrence and progression in non-muscle-invasive bladder cancer. It remains relatively safe, and has acceptable tolerability of both local and systemic side-effects. The present review provides insights into the role of bacillus Calmette-Guérin compared with alternative treatments both in primary and refractory settings...

Objective To examine discomfort, anxiety, and preferences for decision-making in patients undergoing surveillance cystoscopy for non-muscle-invasive bladder cancer (NMIBC). Methods Veterans with a prior diagnosis of NMIBC completed validated survey instruments assessing procedural discomfort, worry, and satisfaction, and were invited to participate in semi-structured focus groups about their experience and desire to be involved in surveillance decision-making. Focus group transcripts were analyzed qualitatively, using (1) systematic iterative coding, (2) triangulation involving multiple perspectives from urologists and an implementation scientist, and (3) searching and accounting for disconfirming evidence...

BACKGROUND: The success of cancer immunotherapies has highlighted the potent ability of local adaptive immune responses to eradicate cancer cells by targeting neoantigens generated by somatic alterations. However, how these factors interact to drive the natural history of muscle-invasive bladder cancer (MIBC) is not well understood. OBJECTIVE: To investigate the role of immune regulation in MIBC disease progression, we performed massively parallel T-cell receptor (TCR) sequencing of tumor-infiltrating T cells (TILs), in silico neoantigen prediction from exome sequences, and expression analysis of immune-related genes...

BACKGROUND: Preclinical studies suggest that signal transducer and activator of transcription 3 (STAT3)-mediated recruitment of neutrophils to premetastatic tissue occurs prior to metastatic progression. OBJECTIVE: We sought to determine if neutrophilic infiltration in benign nodal tissue is associated with poor clinical outcome in patients with muscle-invasive bladder cancer. DESIGN, SETTING, AND PARTICIPANTS: Formalin-fixed, paraffin-embedded tissue was secured from 55 patients with muscle-invasive bladder cancer who had undergone cystectomy at our institution...

Muscle Invasive Bladder Cancer (MIBC) has a poor prognosis. Whilst patients can achieve a 6% improvement in overall survival with Neo-Adjuvant Chemotherapy (NAC), many do not respond. Body fluid mutant DNA (mutDNA) may allow non-invasive identification of treatment failure. We collected 248 liquid biopsy samples including plasma, cell pellet (UCP) and supernatant (USN) from spun urine, from 17 patients undergoing NAC. We assessed single nucleotide variants and copy number alterations in mutDNA using Tagged-Amplicon- and shallow Whole Genome- Sequencing...

BACKGROUND: The recurrence risk stratification and the cost effectiveness of oncological surveillance after radical cystectomy are not clear. We aimed to develop a risk stratification and a surveillance protocol with improved cost effectiveness after radical cystectomy. RESULTS: Of 581 enrolled patients, 175 experienced disease recurrences. The pathology-based protocol presented significant differences in recurrence-free survival between normal- and high-risk patients, but the medical expense was high, especially in normal-risk (≤pT2pN0) patients...

BACKGROUND: The efficacy of an immediate single chemotherapy instillation after transurethral resection of a bladder tumour (TURBT) in patients with non-muscle-invasive bladder cancer (NMIBC) remains a topic of debate. Evidence is even more scarce when an immediate instillation is followed by adjuvant instillations. OBJECTIVE: To compare the effect of a mitomycin C (MMC) instillation within 24h to an instillation 2 wk after TURBT in patients with NMIBC with or without adjuvant instillations...

Expression of the neonatal splice variant of the voltage-gated sodium channel α-subunit (VGSC) subtype Nav1.5 (nNav1.5), encoded by the gene SCN5A, was shown earlier to be upregulated in human breast cancer (BCa), both in vitro and in vivo. Channel activity promoted BCa invasion of Matrigel(®)in vitro and metastasis in vivo. Consequently, expression of nNav1.5 has been proposed as a functional biomarker of BCa cells with metastatic potential. Here, we have determined immunohistochemically both nNav1.5 and total VGSC (tVGSC) protein expression in a range of adult human tissues...

Accumulating evidence has suggested that germline DNA copy number variations (CNVs) affect various disorders, including human malignancies. However, the significance of CNVs in non-muscle invasive bladder cancer (NMIBC) remains unclear. The purpose of the present study was to identify the role of CNVs in NMIBC. Array comparative genomic hybridization (CGH) analysis was performed to search for candidate CNVs associated with NMIBC susceptibility. Quantitative polymerase chain reaction was carried out to evaluate CNVs associated with patient outcome in 189 NMIBC cases...

Bladder cancer, the majority of which is urothelial carcinoma (UC), is a common malignancy worldwide. Genes encoding transmembrane/secretory proteins expressed specifically in certain cancers may be ideal biomarkers for cancer diagnosis and may represent therapeutic targets. In the present study, the expression and function of the bone marrow stromal cell antigen 2 (BST2) gene was analyzed in UC. Reverse transcription-quantitative polymerase chain reaction demonstrated that expression of BST2 in normal tissue samples was the highest in liver tissue...

Muscle-invasive bladder cancer (MIBC) represents a highly aggressive tumor type compared to non-muscle-invasive tumors. MIBC is characterized by specific molecular alterations, which may also modulate extracellular tumorigenic effects. Tumor-associated exosomes, especially exosomal miRNAs, are important regulators in the interaction between tumor cells and tumor microenvironment by affecting tumor-promoting processes in target cells. It is important to analyze whether their exosomal patterns also reflect the specific molecular characteristics of MIBC...

BACKGROUND: Urothelial bladder cancer (UBC) is characterised by a high risk of recurrence. Patient monitoring is currently based on iterative cystoscopy and on urine cytology with low sensitivity in non-muscle-invasive bladder cancer (NMIBC). Telomerase reverse transcriptase (TERT) is frequently reactivated in UBC by promoter mutations. METHODS: We studied whether detection of TERT mutation in urine could be a predictor of UBC recurrence and compared this to cytology/cystoscopy for patient follow-up...

AIMS: To evaluate the relationship between the apparent diffusion coefficient (ADC) value for bladder cancer and the recurrence/progression risk of post-transurethral resection (TUR). METHODS: Forty-one patients with initial and non-muscle-invasive bladder cancer underwent MRI from 2009 to 2012. Two radiologists measured ADC values. A pathologist calculated the recurrence/progression scores, and risk was classified based on the scores. Pearson's correlation was used to analyze the correlations of ADC value with each score and with each risk group, and the optimal cut-off value was established based on receiver operating characteristic (ROC) curve analysis...

Background&Aim: High grade non-muscle invasive bladder cancer (NMIBC) is common in urological practice. Most of these cancers are or become refractory to intravesical immunotherapy and chemotherapy. Here we evaluated the efficacy of combined local bladder hyperthermia and intravesical mitomycin-C (MMC) instillation in patients with high-risk recurrent NMIBC. MATERIALS AND METHODS: Between February 2014 and December 2015, 18 patients with high risk NMIBC were enrolled. Patients were treated in an outpatient basis with 6 weekly induction sessions followed by monthly maintenance sessions with intravesical MMC in local hyperthermia with bladder wall thermo-chemotherapy (BWT) system (PelvixTT system, Elmedical Ltd...
