BACKGROUND/AIM: VAX014 minicells (VAX014) have been previously characterized as an integrin-specific oncolytic biotherapeutic agent. The present study was designed to evaluate the potential of VAX014 as an immediate post-operative intravesical adjuvant therapy in the treatment of non-muscle invasive bladder cancer (NMIBC). MATERIALS AND METHODS: The ability of VAX014 to kill a panel of dissociated urothelial carcinoma cell lines was tested in vitro. In vivo experiments were conducted using a single intravesical dose of VAX014 in the anti-implantation variation of the MB49 syngeneic orthotopic bladder cancer model with tumor implantation and overall survival rates serving as study endpoints...

Non-muscle invasive (superficial) bladder cancer is a low-grade malignancy with good prognosis, while muscle invasive (invasive) bladder cancer is a high-grade malignancy with poor prognosis. N-butyl-N-(4-hydroxybutyl)nitrosamine (BBN) induces superficial bladder cancers with papillary morphology in rats and invasive bladder cancers with infiltrating phenotype in mice. In this study, we analyzed genomic landscapes of rodent BBN-induced bladder cancers using array-based comparative genomic hybridization (array CGH)...

BACKGROUND: Intravesical Bacillus Calmette-Guérin (BCG) instillation has become one of the mainstays of adjunctive therapy in the treatment of superficial bladder cancer. Ophthalmologic complications are rare, but few cases are reported in the literature. METHODS: Retrospective observational case report. RESULTS: The authors report a case of unilateral Mycobacterium bovis BCG endophthalmitis after intravesical BCG instillations. Despite appropriate systemic antituberculous and corticosteroid therapy, the patient almost completely lost sight in the affected eye...

Patients with superficial bladder cancers remain clinically indolent after treatment with even a modicum of urologic intervention. However, with more invasive disease, the majority of patients experience recurrence. The conventional route of metastasis and recurrence in primary urothelial cell carcinoma is through lymphatic system, with regional lymph nodes, lungs, liver, brain, and bone being the most common sites. Isolated intraluminal colonic recurrence in the absence of local invasion is extremely rare...

The use of live attenuated intravesicular Bacillus Calmette-Guerin (BCG) therapy is a generally accepted safe and effective method for the treatment of superficial transitional cell carcinoma (TCC) of the bladder. Although rare, < 5% of patient's treated with intravesicular BCG therapy may develop potentially serious complications, including localized infections to the genitourinary tract, mycotic aneurysms and osteomyelitis. We present here a case of a 63-year-old male who developed left coronary and multiple peripheral M...

BACKGROUND: Pathological stage and grade have limited ability to predict the outcomes of superficial urothelial bladder carcinoma at initial transurethral resection (TUR). AT-motif binding factor 1 (ATBF1) is a tumor suppressive transcription factor that is normally localized to the nucleus but has been detected in the cytoplasm in several cancers. Here, we examined the diagnostic value of the intracellular localization of ATBF1 as a marker for the identification of high risk urothelial bladder carcinoma...

There are very few biomarkers used to diagnose bladder cancer and no clinically approved biomarkers for prediction or prognostication of this disease. All currently available biomarkers are based on urine tests, and thus, they may not be applicable to patients with extravesical tumors. Biopsy of metastatic sites requires an invasive procedure, whereas serum-based markers, which can be easily obtained and serially measured, thus have obvious merit. These deficiencies may be overcome with advances in genome sequencing, identification of circulating tumor cells, and RNA-, protein-, and DNA-based biomarkers...

Bladder cancer is very common and most cases are diagnosed as nonmuscle invasive disease, which is characterized by its propensity to recur and progress. Intravesical therapy is used to delay recurrence and progression, while cystectomy is reserved for patients who are refractory to transurethral resection and intravesical therapy. There is an increasing interest in methods to enhance the delivery of intravesical chemotherapeutic agents to improve efficacy. In vitro and in vivo studies demonstrated that electro-osmosis of mitomycin C (MMC) is more effective in delivering this drug into the urothelium, lamina propria, and superficial muscle layers of the bladder wall than is passive transport...

Non-muscle-invasive bladder cancer (NMIBC) often has a worse prognosis following its progression to muscle-invasive bladder cancer (MIBC), despite radical cystectomy with pelvic lymph node dissection combined with chemotherapy. Therefore, the discovery of novel biomarkers for predicting the progression of this disease and of therapeutic targets for preventing it is crucial. We performed whole-exome sequencing to analyze superficial tumor tissues (Tsup) and basal tumor tissues (Tbas) from 3 MIBC patients and identified previously unreported copy number variations in IPO11 that warrants further investigation as a molecular target...

OBJECTIVE: The loosening of total joint replacement is a frequent complication after total hip arthroplasty (THA). Septic osteolysis should always be feared. We report here a rare case of hip arthroplasty infection due to Mycobacterium bovis after Bacillus Calmette-Guerin (BCG) therapy in a context of bladder cancer. OBSERVATIONS: A 70-year-old man was referred to the department of rheumatology in September 2015, because of a total functional disability of the left lower limb...

BACKGROUND: It has been suggested that bladder cancer can be divided into two molecular subtypes referred to as luminal and basal with distinct clinical behaviors and sensitivities to chemotherapy. We aimed to validate these subtypes in several clinical cohorts and identify signature immunohistochemical markers that would permit simple and cost-effective classification of the disease in primary care centers. METHODS: We analyzed genomic expression profiles of bladder cancer in three cohorts of fresh frozen tumor samples: MD Anderson (n=132), Lund (n=308), and The Cancer Genome Atlas (TCGA) (n=408) to validate the expression signatures of luminal and basal subtypes and relate them to clinical follow-up data...

Hypoxia-inducible factor-1α (HIF-1α) can control a transcriptional factor forkhead box P3 (Foxp3) protein expression in T lymphocyte differentiation through proteasome-mediated degradation. In this study, we unveil a reverse regulatory mechanism contributing to bladder cancer progression; Foxp3 expression attenuates HIF-1α degradation. We first demonstrated that Foxp3 expression positively correlates with the metastatic potential in T24 cells and can increase the expression of HIF-1α-target genes, such as vascular endothelial growth factor (VEGF) and glucose transporter (GLUT)...

BACKGROUND: Transurethral resection of bladder tumor (TURBT) technique has been considered the routine method for removing most bladder tumors for decades. In contrast, endoscopic submucosal dissection (ESD) is the gold-standard treatment for gastrointestinal superficial tumors. We investigated the effectiveness and applicability of a new technique for en bloc bladder tumor resection using ESD procedure. METHODS: Four Landrace Large White Duroc female pigs were anesthetized with isoflurane prior endoscopic resection using a large-caliber prototype fiber bronchoscope...

Radix Paeoniae Rubra (RPR) is the dried root of Paeonia lactiflora Pallas and Paeonia veitchii Lynch, and is a herbal medicine that is widely used in traditional Chinese medicine for the treatment of blood-heat and blood-stasis syndrome, similarly to Cortex Moutan. The present study identified the same three components in RPR and Cortex Moutan extracts. In addition, it has been reported that RPR has an anti-cancer effect. Bladder cancer is the seventh most common type of cancer worldwide. Due to the high recurrence rate, identifying novel drugs for bladder cancer therapy is essential...

Human AlkB homolog 8 (ALKBH8) is highly expressed in high-grade, superficially and deeply invasive bladder cancer. Moreover, ALKBH8 knockdown induces apoptosis in bladder cancer cells. However, the underlying anti-apoptotic mechanism of ALKBH8 in bladder cancer cells has thus far remained unclear. Moreover, there is no direct evidence that highly expressed ALKBH8 is involved in tumor progression in vivo. We here show that ALKBH8 knockdown induced apoptosis via downregulating the protein expression of survivin, an anti-apoptotic factor also exhibiting increased levels in bladder cancer...

The urothelium is a specialized epithelium that lines the urinary tract. It consists of three different cell types, namely, basal, intermediate and superficial cells arranged in relatively distinct cell layers. Normally, quiescent, it regenerates fast upon injury, but the regeneration process is not fully understood. Although several reports have indicated the existence of progenitors, their identity and exact topology, as well as their role in key processes such as tissue regeneration and carcinogenesis have not been clarified...
