Bladder cancer is nowadays a common tumor. Non-muscle invasive bladder cancer (NMIBC) has still chances of recurrence and progression in spite of surgery and adjuvant treatments. New therapies are being developed to reduce these percentages with less adverse effects - Apaziquone (EO9) is an example. Areas covered: A literature search has been performed using Pubmed, UpToDate and Google verified information (mainly from Food and Drug Administration and Spectrum Pharmaceutics websites). We have included data from the most representative clinical trials and reviews published...

The development is reported of an ultra-rapid, point-of-care diagnostic device which harnesses surface acoustic wave (SAW) biochips, to detect HIV in a finger prick of blood within 10 seconds (sample-in-result-out). The disposable quartz biochip, based on microelectronic components found in every consumer smartphone, is extremely fast because no complex labelling, amplification or wash steps are needed. A pocket-sized control box reads out the SAW signal and displays results electronically. High analytical sensitivity and specificity are found with model and real patient blood samples...

A significant number of patients with intermediate- or high-risk bladder cancer treated with intravesical Bacillus Calmette-Guérin (BCG) immunotherapy are non-responders to this treatment. Since we cannot predict in which patients BCG therapy will fail, markers for responders are needed. UroVysion(®) is a multitarget fluorescence in situ hybridization (FISH) test for bladder cancer detection. The aim of this study was to evaluate whether FISH can be used to early identify recurrence during treatment with BCG...

BACKGROUND: H-NS family proteins are nucleoid-associated proteins that form oligomers on DNA and function as global regulators. They are found in both bacterial chromosomes and plasmids, and were suggested to be candidate effectors of the interaction between them. TurA and TurB are the predominantly expressed H-NS family proteins encoded on the chromosome of Pseudomonas putida KT2440, while Pmr is encoded on the carbazole-degradative incompatibility group P-7 plasmid pCAR1. Previous transcriptome analyses suggested that they function cooperatively, but play different roles in the global transcriptional network...

AIMS: The large nested variant of urothelial carcinoma (LNUC) has been added to the World Health Organization (WHO) 2016 classification. Scant data exist, and little is known about its clinical behaviour. MATERIAL AND RESULTS: Cases fulfilling the morphological criteria of LNUC were collected. Pure and mixed cases (i.e. with other patterns of invasive UC) were studied. Immunohistochemical staining with cytokeratin (CK)7, p63, GATA-3, CK20, p53 and Ki-67 was performed...

Preventing the spread of infectious diseases remains an urgent priority worldwide, and this is driving the development of advanced nanotechnology to diagnose infections at the point of care. Herein, we report the creation of a library of novel nanobody capture ligands to detect p24, one of the earliest markers of HIV infection. We demonstrate that these nanobodies, one tenth the size of conventional antibodies, exhibit high sensitivity and broad specificity to global HIV-1 subtypes. Biophysical characterization indicates strong 690 pM binding constants and fast kinetic on-rates, 1 to 2 orders of magnitude better than monoclonal antibody comparators...

Our reported case is a 72 year-old man who presented with hematuria. A transurethral resection of the bladder tumor (TURB-T) has been performed. Histopathological diagnosis was an epithelioid angiosarcoma. CT scan revealed a bladder thickening. The treatment consisted in a complete pelvectomy with urinary and digestive diversion. Following the operation, the patient developed liver and pulmonary metastasis. He died 5 months after the initial diagnosis.

INTRODUCTION: Determining the clinical stage of bladder carcinoma before radical cystectomy is characterized by a high inaccuracy rate. The discrepancy in some reports reaches up to 48%. Therefore intraoperative clinical staging of bladder carcinoma is not recommended before radical treatment as it is for prostate cancer. However, the accuracy of clinical assessment of the muscle invasive character of the tumors at the time of transurethral resection has not been studied. In our study we estimate the accuracy of clinical staging during endoscopic treatment...

INTRODUCTION: The study aimed to investigate the diagnostic utility of diffusion-weighted MRI (DW-MRI) in differentiating residual bladder cancer from benign postoperative changes before a second transurethral resection of the bladder (TURB). MATERIALS AND METHODS: Of the 75 bladder cancer patients who underwent a second TURB from 2013 to 2015, 23 patients who underwent multi-sequence bladder MRI after their initial TURB were retrospectively evaluated. Thirty lesions were histologically examined at the second TURB and the results of them were compared with the findings obtained through T2-weighted MRI, dynamic contrast-enhanced MRI (DCE-MRI), and DW-MRI...

PURPOSE: Bladder cancer (BC) is one of the most common cancers worldwide. BC diagnosis and surveillance is based on cystoscopy (CS). CS impact on patient's depression, anxiety, and sexual satisfaction (SS) is not sufficiently studied. There are no data on patient's comfort with flexible or rigid CS. METHODS: We prospectively evaluated pain perception (PP), depression, anxiety, and SS of 100 male patients who previously underwent at least one rigid CS in our department as surveillance after TURB procedure due to non-muscle-invasive BC and were scheduled for the next CS examination...

The prognostic role of systemic inflammatory response (SIR) markers is unclear in patients with non-muscle invasive bladder cancer (NMIBC). Here, we aimed to investigate the prognostic role of various SIR markers in the oncological outcomes in non-muscle invasive bladder cancer (NMIBC) patients at a single institution in Korea. Neutrophil-lymphocyte ratio (NLR), derived-NLR (dNLR), and platelet-lymphocyte ratio (PLR) were examined as SIR markers. We retrospectively collected data of 1,698 NMIBC patients who underwent transurethral resection of the bladder (TURB) between 1990 and 2013...

PURPOSE OF REVIEW: The recurrence rate in patients with nonmuscle invasive bladder cancer is high, and the quality of transurethral resection of the bladder (TURB) tumour influences recurrence risk. We review new methods that aim to improve the effectiveness of TURB, and highlight studies of the past year. RECENT FINDINGS: Several approaches have been explored: bipolar resection is well tolerated and efficient; however, surgical outcomes are not clearly superior to monopolar resection; en-bloc resection seems feasible and well tolerated, and has the potential to improve the quality of tissue for histopathology; enhancement techniques such as photodynamic diagnosis, narrow band imaging, and Image1 S improve tumour detection, whereas photodynamic diagnosis reduces recurrence rates; high-resolution imaging modality such as confocal laser endomicroscopy may provide histopathologic information...

PURPOSE: To evaluate the effect of preoperative anemia (PA) on oncological outcomes in a multicenter cohort of patients with non-muscle-invasive bladder cancer (NMIBC) treated with transurethral resection of the bladder (TURB) and adjuvant intravesical therapies. We hypothesize that PA represents a marker of disease aggressiveness and could be used to improve the discrimination of prognostic tools for the prediction of disease recurrence and progression. METHODS: This multicenter retrospective study included 1,117 patients from 4 different centers...

BACKGROUND: Sarcomatoid urothelial carcinoma (SUC) is a rare malignant neoplasm of the urinary bladder comprising 0.2-0.6 % of all histological bladder tumor subtypes. It presents as a high-stage malignancy and exhibits aggressive biological behavior, regardless of the treatment employed. It is defined as histologically indistinguishable from sarcoma and as a high-grade biphasic neoplasm with malignant epithelial and mesenchymal components. The mean age of patients presenting with SUC is 66 years, and the male-to-female ratio is 3:1...

Non-muscle-invasive bladder cancer (NMIBC) is characterised by a high risk of recurrence when performing only a transurethral resection of the bladder (TURB). Intravesical instillations are performed postoperatively to decrease the rate of recurrence. The standard agents currently used are Mitomycin-C (MMC) or bacillus Calmette-Guérin (BCG). In order to further enhance the efficacy of the adjuvant treatments and/or diminish their side effects, alternative treatments are studied. Intravesical MMC combined with hyperthermia could be an interesting alternative active treatment for intermediate- and possibly high-risk NMIBC, and has been investigated in the past years...

PURPOSE: White light cystoscopy (WLC) is the standard procedure for visualising non-muscle invasive bladder cancer (NMIBC). However, WLC can fail to detect all cancerous lesions, and outcomes with transurethral resection of the bladder differ between institutions, controlled trials, and possibly between trials and routine application. This noninterventional study assessed the benefit of hexaminolevulinate blue light cystoscopy (HALC; Hexvix(®), Ipsen Pharma GmbH, Germany) plus WLC versus WLC alone in routine use...
