BACKGROUND: Open radical cystectomy (ORC) is regarded the standard treatment for muscle-invasive bladder cancer, but robot-assisted radical cystectomy (RARC) is increasingly used in practice. However, it is unclear whether RARC provides value for money. OBJECTIVE: To identify the main evidence gaps and main drivers of cost-effectiveness, comparing RARC to ORC. DESIGN, SETTING, AND PARTICIPANTS: A decision analytical model was developed to study the 30d and 90d postoperative complications with RARC versus ORC and their related cost in bladder cancer patients...

Intravesical Bacillus Calmette-Guérin (BCG) is widely used for high-risk, non-muscle-invasive bladder cancer. We describe four cases which illustrate the spectrum of BCG-induced complications, varying from granulomatous prostatitis to sepsis. Considerable debate exists whether inflammation or infection is the predominant mechanism in the pathogenesis of BCG-disease. In two patients with systemic illness symptoms resolved first after adding prednisone, indicating a principle role for inflammation in systemic disease...

PURPOSE: To investigate whether a history of non-muscle-invasive bladder cancer (NMIBC) plays a prognostic role in patients with muscle-invasive bladder cancer (MIBC) treated with radical cystectomy in the era when neoadjuvant chemotherapy was established as standard therapy for MIBC. PATIENTS AND METHODS: A total of 282 patients who were diagnosed with cT2-T4aN0M0 bladder cancer treated with open radical cystectomy at our institutions were included. Initially diagnosed MIBC without a history of NMIBC was defined as primary MIBC group (n = 231), and MIBC that progressed from NMIBC was defined as progressive MIBC (n = 51)...

We undertook a systematic evaluation of the prognostic value of numerous histologic factors in 165 radical cystectomies (RC) of patients with invasive urothelial carcinoma who underwent surgery after neoadjuvant chemotherapy (NAC). Tumor regression grade (TRG) and therapy-related stromal and epithelial changes were also recorded. Locally advanced disease (≥pT2 and/or pN+) was present in 64% of patients, 22% had no evidence of residual carcinoma (pT0+pN0) and 28% had no evidence of residual muscle invasive carcinoma (≤pT1+N0)...

INTRODUCTION: Radical cystectomy and extended pelvic lymph node dissection (ePLND) are the gold standard treatment for muscle-invasive bladder cancer and BCG unresponsive nonmuscle-invasive bladder cancer. In this article, we review the rationale for ePLND in the treatment of bladder cancer and the evidence supporting the equipoise between robot-assisted (RA) and open ePLND. A step-by-step guide of robot-assisted ePLND (RA ePLND) is provided to illustrate the techniques currently employed at our institution...

Intravesical Bacillus Calmette-Guerin (BCG) immunotherapy is a proven, effective treatment for intermediate- and high-risk non-muscle-invasive bladder cancer. Minor side effects are common and expected but systemic effects can occur in <5% of treated patients. We present a rare case of a 49-year-old male that presented with fever and chills after 3 weeks of intravesical BCG therapy post transurethral resection of bladder tumor. New renal lesions were present on contrast-enhanced computed tomography scan which was histologically proven to be necrotizing renal granulomatosis...

Conflicting results of survival outcomes for primary and secondary muscle-invasive bladder cancer (MIBC) have been reported in previous studies. Primary MIBC is defined as presentation of muscle-invasive disease at initial diagnosis while secondary MIBC presumes that non-muscle invasive disease later progressed to MIBC. Due to the varying reports, we conducted a systematic review and meta-analysis to compare survival outcomes between the two groups. Relevant studies were retrieved from Medline, Embase, the Cochrane Library, and Scopus using a comprehensive search approach...

BACKGROUND AND OBJECTIVE: Muscle-invasive bladder cancers (MIBCs) are heterogeneous cancers and can be grouped into basal-like and luminal subtypes that are highly reminiscent of those found in breast cancer. Like basal-like breast cancers, basal-like MIBCs are associated with advanced stage and metastatic disease. However, the biological and clinical significance of molecular subtypes of MIBCs remain unclear. Therefore, we implemented a serious of bioinformatics methods to explore genetic similarities between bladder and breast cancers...

Previous studies on metabolic factors and bladder cancer (BC) risk have shown inconsistent results and have commonly not investigated associations separately by sex, smoking, and tumor invasiveness. Among 811 633 participants in six European cohorts, we investigated sex-specific associations between body mass index (BMI), mid-blood pressure (BP, [systolic+diastolic]/2), plasma glucose, triglycerides, total cholesterol and risk of BC overall, non-muscle invasive BC (NMIBC) and muscle invasive BC (MIBC). Among men, we additionally assessed additive interactions between metabolic factors and smoking on BC risk...

CONTEXT: Management of bladder cancer (BC) is primarily driven by stage, grade, and biological potential. Knowledge of each is derived using clinical, histopathological, and radiological investigations. This multimodal approach reduces the risk of error from one particular test, but may present a staging dilemma when results conflict. Multiparametric magnetic resonance imaging (mpMRI) may improve patient care through imaging of the bladder with better resolution of the tissue planes than computed tomography and without radiation exposure...

BACKGROUND: Bacille of Calmette et Guérin (BCG) immunotherapy is the most effective treatment for non-muscle-invasive bladder cancer. Yet, potentially severe localized or systemic mycobacterial infections can happen. STATE OF KNOWLEDGE: In a patient who underwent BCG instillation for bladder cancer, the diagnosis of BCG infection is usually suggested by more than 3 days of high-grade fever and systemic and/or local symptoms with no other plausible alternative diagnosis...

Bacilus Calmette-Guerin (BCG) administered intravesical is an effective therapy in non muscle invasive bladder cancer (NMIBC), but it presents limitations regarding recurrence and toxicity. For years, many case series have been published where sequential therapy with BCG and Mitomycin C (MMC) was tried. In this article, we perform a review of the data supplied by these articles with the aim to determine the safety and efficacy of combination, and what is the group of patients it should be indicated. Many studies show that combination therapy did not cause more toxicity and improved the interval free of disease with decrease of tumor progression compared to BCG or MMC monotherapy...

Disease recurrence and progression remain as significant challenges for the management of non-muscle invasive bladder cancer (NMIBC). In recent years, novel drugs and delivery systems have been investigated as strategies to reduce recurrence, progression and mortality. In this review, we focus on the role of intravesical hyperthermic chemotherapy and discuss a novel approach involving a heat-activated drug delivery system (ThermoDox®) that enables local accumulation of systemic chemotherapy.

OBJECTIVES: The treatment of non muscle invasive bladder cancer (NMIBC) continues to be a challenge. Hyperthermia (HT) combined with intravesical chemotherapy is used to enhance the effects of chemotherapy. METHODS: A review of the publications was carried out to synthesize the adverse effects (AE) reported by the use of chemohyperthermia (QHT) with Mitomycin-C (MMC). The most relevant data are exposed for each of the devices currently used in the QHT. RESULTS: SYNERGO®: The dropout rate varied between 3-40%, and the AE rate is up to 88%...

In an effort to decrease recurrence and progression rates in non-muscle-invasive bladder cancer (NMIBC), transurethral resection of a bladder tumor is followed by intravesical instillations using Mitomycin-C (MMC) and Bacillus Calmette-Guérin (BCG). In spite of these adjuvant treatment modalities, recurrence and progression rates remain high. Because of these limitations of current standard therapy and the shortage of BCG, there is a search for alternative forms of treatment in NMIBC. Intravesical MMC combined with hyperthermia, especially RF-induced QHT being most extensively investigated in the past 20 years, is one of these alternatives for intermediate- and high-risk NMIBC...

Urothelial bladder cancer is a very prevalent disease. At the time of diagnosis 70-80% of the cases present as non muscle invasive tumors. These tumors present a high recurrence and progression rates despite intravesical treatment with Bacille Calmette-Guerin and mitomycin C. Moreover, bladder conditions such as its wall impermeability and the fact that intravesical drugs are constantly being diluted by urine and eliminated do not favor the efficacy of intravesical treatment. This review analyzes new intravesical drugs such as gemcitabine or taxanes with promising results as alternative to the usual treatments or after their failure...

Bladder cancer is the 9th most prevalent cancer in the world. It is divided into muscle invasive bladder cancer (MIBC) and non muscle invasive bladder cancer (NMIBC). Over 75% belong to the second group and it will be classified according to the risk of progression and recurrence. In high and intermediate risk tumors. There is indication for the use of bladder instillations with BCG as it reduces the number of recurrences and disease progression to MIBC. In spite of this, disease control is not possible in all cases and there could be recurrence or progression of the disease to MIBC...
