Vascular mimicry (VM) refers to the plasticity of aggressive cancer cells forming de novo vascular networks, which promoted tumor metastasis. The aim of this study was evaluate the impact of VM on recurrence-free survival (RFS) in urothelial carcinoma of the bladder (UCB). Records from 202 patients treated with radical cystectomy (RC) for UCB at Zhongshan Hospital between 2002 and 2014 were reviewed. The presence of VM was identified by CD31-PAS double staining. Positive VM staining occurred in 19.3% (39 of 202) UCB cases, and it was associated with increased risks of recurrence (Log-Rank p<0...

PURPOSE: The aim of this study was to conduct a prospective pilot study comparing the diagnostic performance of MRI alone and F-FDG simultaneous PET/MRI using a diuresis protocol in bladder cancer patients. METHODS: Twenty-two bladder cancer patients underwent F-FDG PET/MRI, using intravenous furosemide and oral hydration for bladder clearance. A radiologist scored probability of tumor in 3 locations (urinary bladder, pelvic lymph nodes, nonnodal pelvis) using 1- to 3-point scale (1 = negative, 2 = equivocal, 3 = definite tumor)...

Importance: State-specific information about the health burden of smoking is valuable because state-level initiatives are at the forefront of tobacco control. Smoking-attributable cancer mortality estimates are currently available nationally and by cancer, but not by state. Objective: To calculate the proportion of cancer deaths among adults 35 years and older that were attributable to cigarette smoking in 2014 in each state and the District of Columbia. Design, Setting, and Participants: The population-attributable fraction (PAF) of cancer deaths due to cigarette smoking was computed using relative risks for 12 smoking-related cancers (acute myeloid leukemia and cancers of the oral cavity and pharynx; esophagus; stomach; colorectum; liver; pancreas; larynx; trachea, lung, and bronchus; cervix uteri; kidney and renal pelvis; and urinary bladder) from large US prospective studies and state-specific smoking prevalence data from the Behavioral Risk Factor Surveillance System...

Capsaicin (CAP), a highly selective agonist for transient receptor potential vanilloid type 1 (TRPV1), has been widely reported to exhibit anti-oxidant, anti-inflammation and anticancer activities. Currently, several therapeutic approaches for bladder cancer (BCa) are available, but accompanied by unfavorable outcomes. Previous studies reported a potential clinical effect of CAP to prevent BCa tumorigenesis. However, its underlying molecular mechanism still remains unknown. Our transcriptome analysis suggested a close link among calcium signaling pathway, cell cycle regulation, ROS metabolism and FOXO signaling pathway in BCa...

Understanding the global interaction dynamics between tumor and the immune system plays a key role in the advancement of cancer therapy. Bunimovich-Mendrazitsky et al. (2015) developed a mathematical model for the study of the immune system response to combined therapy for bladder cancer with Bacillus Calmette-Guérin (BCG) and interleukin-2 (IL-2) . We utilized a mathematical approach for bladder cancer treatment model for derivation of ultimate upper and lower bounds and proving dissipativity property in the sense of Levinson...

In this work, we investigate chemo- thermotherapy, a recently clinically-approved post-surgery treatment of non muscle invasive urothelial bladder carcinoma. We developed a mathematical model and numerically simulated the physical processes related to this treatment. The model is based on the conductive Maxwell's equations used to simulate the therapy administration and Convection-Diffusion equation for incompressible fluid to study heat propagation through the bladder tissue. The model parameters correspond to the data provided by the thermotherapy device manufacturer...

OBJECTIVE: We present our experience in the diagnosis and management of anterior urethral valves (AUV) and anterior urethral diverticula (AUD) as well as review of the bibliography. MATERIALS AND METHODS: We retrospectively evaluated all the cases of the AUV and AUD treated in our hospital during the last 10 years. The clinical exploration, renal function study and renal and bladder ultrasound were evaluated in all the children. The diagnosis was completed with voiding cystography (VCUG) and cystoscopy as well as nuclear study in the relevant patients...

BACKGROUND: Urine cytology is the most frequently utilized test to detect urothelial cancer. Secondary bladder neoplasms need to be recognized as this impacts patient management. We report our experience on nonurothelial malignancies (NUM) detected in urine cytology over a 10-year period. METHODS: A 10-year retrospective search for patients with biopsy-proven NUM to the urothelial tract yielded 25 urine samples from 14 patients. Two cytopathologists blinded to the original cytology diagnosis reviewed the cytology and histology slides...

PURPOSE: Intermittent catheterization (IC) often is essential for individuals with spina bifida/myelomeningocele (SBM) and neurogenic bladder. This study aimed to identify and analyze the factors that influence the use of IC. DESIGN AND METHODS: Descriptive study with convenience sampling. Data were collected using printed (Brazil) and online (Germany) questionnaires, and analyzed using multivariate logistical regression and analysis of variance. The study included 100 Brazilian and 100 German patients, aged 0-55 years, with SBM who utilized IC...

Strategies to identify tumors at highest risk for treatment failure are currently under investigation for patients with bladder cancer. We demonstrate that flow cytometric detection of poorly differentiated basal tumor cells (BTCs), as defined by the co-expression of CD90, CD44 and CD49f, directly from patients with early stage tumors (T1-T2 and N0) and patient-derived xenograft (PDX) engraftment in locally advanced tumors (T3-T4 or N+) predict poor prognosis in patients with bladder cancer. Comparative transcriptomic analysis of bladder tumor cells isolated from PDXs indicates unique patterns of gene expression during bladder tumor cell differentiation...

BACKGROUND: Diabetes mellitus is a vastly prevalent metabolic disorder with escalating global health concerns. Particularly when mismanaged, chronic micro- and macrovascular complications may highly impair physiological systems while immunodeficiency disposes us to infection. OBJECTIVE: We investigate infections, localized complications, and neoplasms of the genitourinary system secondary to the chronic complications of diabetes mellitus in males and females. METHOD: A comprehensive MEDLINE® search was guided using key words relevant to diabetes mellitus and the genitourinary system...

Three isolectins denoted hereforth MBaL-30, MBaL-60, and MBaL-80 were isolated from seeds extract of Momordica balsamina by 30%, 60%, and 80% ammonium sulfate saturations, respectively. The native molecular weights of these lectins, as judged by gel filtration, were 108, 56, and 160 kDa, respectively. On SDS-PAGE, under reduced condition, 27 kDa band was obtained for all isolectins. The lectins hemagglutinating activities were variably inhibited by d-galactose (minimum inhibitory concentrations = 12.5mM, 50mM, and 0...

Piroxicam is a benzothiazine compound with anti-inflammatory, antipyretic, and analgesic properties. Because of the very high efficacy of piroxicam and its increasing use in the treatment of carcinomas in dogs and cats, there is a need for acute toxicity study of piroxicam in monogastric animals and its potential for causing secondary poisoning in puppies. Piroxicam manufactured by Shanxi Federal Pharmaceutical Co, Ltd. was used for this study. Revised up-and-down procedure was used for the estimation of median lethal dose in mouse (259...

AIM: Increased afferent fibre activity contributes to pathological conditions such as the overactive bladder syndrome. Nerve fibres running near the urothelium are considered to be afferent as no efferent system has yet been described. The aim of this study was to identify sub-types of afferent nerve fibres in the mouse bladder wall based on morphological criteria and analyse regional differences. MATERIALS AND METHODS: 27 bladders of six month old C57BL/6 mice were removed and tissues were processed for immunohistochemistry...

BACKGROUND/AIMS: To investigate the potential inhibitory effects of 18 clinically available antidepressants on acetylcholine (ACh)-induced contractions in guinea pig urinary bladder smooth muscle (UBSM) in order to predict whether they may induce voiding impairment. METHODS: Concentration-response curves for ACh-induced contractions in guinea pig UBSM strips were obtained in the absence or presence of selected antidepressants. When inhibitory effects indicated competitive antagonism, pA2 values against ACh were calculated and compared to plausible antidepressant blood concentrations...
