OBJECTIVE: Unlike for bladder cancer, the impact of regional lymph node dissection for upper tract urothelial carcinoma is unclear. We explored whether patient survival was influenced by systematic regional lymph node dissection, using resection templates according to the main tumor location, during radical nephroureterectomy for upper tract urothelial carcinoma. METHODS: The systematic regional lymph node dissection group was defined as cases in which the dissection of nodes and surrounding tissues followed the established template, and the non-systematic regional lymph node dissection group as cases undergoing limited or no lymph node dissection...

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...

PURPOSE: Urine fluorescence in situ hybridization (FISH) has become a broadly used marker for noninvasive detection of bladder cancer (BC). However, it has been discussed whether the interpretation algorithm proposed by the manufacturer could be improved. Aim of the present study was to compare alternative evaluation strategies of FISH for detection of BC. METHODS: We included 1048 patients suspicious for BC, who underwent urine FISH examination before cystoscopy (diagnostic cohort)...

The goal of this article is to provide recommendations for the diagnosis and treatment of muscle-invasive and metastatic bladder cancer. The diagnosis of muscle-invasive bladder cancer is made by pathologic evaluation after transurethral resection. Recently, a molecular classification has been proposed. Staging of muscle-invasive bladder cancer must be done by computed tomography scans of the chest, abdomen and pelvis and classified on the basis of UICC system. Radical cystectomy and lymph node dissection are the treatment of choice...

PURPOSE: Tobacco smoking and occupational exposures are the leading risk factors for developing urothelial bladder carcinoma (UBC), yet little is known about the contribution of these two factors to risk of UBC recurrence. We evaluated whether smoking status and usual adult occupation are associated with time to UBC recurrence for 406 patients with muscle-invasive bladder cancer submitted to The Cancer Genome Atlas (TCGA) project. METHODS: Kaplan-Meier and Cox proportional hazard methods were used to assess the association between smoking status, employment in a high-risk occupation for bladder cancer, occupational diesel exhaust exposure, and 2010 Standard Occupational Classification group and time to UBC recurrence...

Locally advanced (T3b, T4 and N1-N3) and metastatic urothelial bladder cancer (BCa) is a lethal disease with poor survival outcomes. Combination chemotherapy remains the treatment of choice in patients with metastatic disease and an important part of treatment in addition to radical cystectomy (RC) in patients with locally advanced tumour. Approximately half of patients who underwent RC for muscle invasive BCa relapse after surgery with either local recurrence or distant metastasis. This review focuses on the management of muscle invasive, locally advanced and metastatic BCa with emphasis on the role of surgery; to summarize the current knowledge in order to enhance clinical decision-making and counselling process...

Bladder cancer (BC) is a frequent type of carcinoma with an estimated incidence of approximately 100,000 men and women each year in the European Union (EU) with an associated mortality of 30,000 of these patients. In more than 70% the disease is diagnosed in a non-muscle invasive stage with the chance of minimally invasive, local treatment only, which might be required repetitively due to high rate of recurrence. In contrast, muscle invasive or metastatic stages need multimodal treatment strategies including surgical treatment and chemotherapy (CTX) in neoadjuvant (NAC), adjuvant, or palliative settings...

While men are at a considerable higher risk of developing urothelial carcinoma of the bladder (UCB), women present with more advanced disease stages and seem to experience unfavorable outcomes. Evaluating specific differences in the UCB incidence and outcomes between both genders in the non-muscle invasive, muscle-invasive or locally advanced and metastatic setting, as well as determining the underlying causes of disease, may allow optimizing treatment and improving the quality of urological care among both genders...

OBJECTIVE: Checkpoint inhibitors have rapidly become a standard treatment option for metastatic urothelial carcinoma. A wave of enthusiasm for these drugs has pushed them also into the setting of localized bladder cancer, including both non-muscle-invasive bladder cancer (NMIBC) and muscle-invasive disease bladder cancer (MIBC). Here, we aimed to review the emerging role of checkpoint inhibition in localized bladder cancer. METHODS: We reviewed the current treatment landscape for both NMIBC and MIBC and established a significant unmet clinical need for novel therapies...

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...

Bladder cancer is one of the leading causes of death in Europe and the United States. About 25% of patients with bladder cancer have advanced disease (muscle-invasive or metastatic disease) at presentation and are candidates for systemic chemotherapy. In the setting of metastatic disease, use of cisplatin-based regimens improves survival. However, despite initial high response rates, the responses are typically not durable leading to recurrence and death in the vast majority of these patients with median overall survival of 15months and a 5-year survival rate of ⩽10%...

Bladder cancer is the fifth most common in incidence and one of the most expensive cancers to treat. Early detection greatly improves the chances of survival and bladder preservation. The pH low insertion peptide (pHLIP) conjugated with a near-infrared fluorescent dye [indocyanine green (ICG)] targets low extracellular pH, allowing visualization of malignant lesions in human bladder carcinoma ex vivo. Cystectomy specimens obtained after radical surgery were immediately irrigated with nonbuffered saline and instilled with a solution of the ICG pHLIP construct, incubated, and rinsed...

BACKGROUND: Systemic chemotherapy with gemcitabine and cisplatin is standard of care for patients with metastatic urothelial bladder cancer. However, resistance formation is common after initial response. The protein Src is known as a proto-oncogene, which is overexpressed in various human cancers. Since there are controversial reports about the role of Src in bladder cancer, we evaluated the efficacy of the Src kinase inhibitor dasatinib in the urothelial bladder cancer cell line RT112 and its gemcitabine-resistant sub-line RT112(r)GEMCI(20) in vitro and in vivo...

Urothelial cell carcinoma (UCC) metastases to skeletal muscle are extremely rare and usually found in patients with advanced stage cancer. The most common sites of bladder cancer metastases are lymph nodes, lung, liver, and bones. Muscle is an unusual site of metastases from a distant primary cancer, due to several protective factors. We present a rare case of 76-year-old patient with metastases in the flexor digitorum superficialis (FDS) and flexor digitorum profundus (FDP) muscles, 2 years after a radical cystectomy for invasive UCC of the bladder...
