CONTEXT: Urothelial carcinoma is considered a pan-urothelial disease. As such, the remnant urothelium in the upper urinary tract and urethra following radical cystectomy (RC) remains at risk for secondary urothelial tumors (SUTs). OBJECTIVE: To describe the incidence, diagnosis, treatment, and outcomes of patients with SUTs after RC. EVIDENCE ACQUISITION: A systematic search was conducted using PubMed database according to Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines to identify studies between 1970 and 2016 reporting on malignant diseases of the urothelium after RC for bladder cancer...

PURPOSE: Although radical cystectomy is still considered the standard of care for most localized muscle-invasive bladder cancer (MIBC) patients, bladder-sparing strategies with chemoradiotherapy have demonstrated comparable local control and survival rates when adjusting for tumor stage. We present a pooled analysis of individual patient data out of published trials with gemcitabine-based chemoradiotherapy for MIBC. METHODS AND MATERIALS: Individual patient data were collected from Institutions that enrolled patients into trials that evaluated gemcitabine-based chemoradiotherapy for MIBC...

INTRODUCTION: Among available urinary diversion, continent cutaneous urinary diversion (CCUD) is not frequently used after cystectomy for malignancy. The aim of our work was to assess mid-term oncological and functional outcomes of CCUD in case of malignancies. PATIENTS AND METHODS: We retrospectively included all patients who underwent CCUD after radical cystectomy for cancer (according Mitrofanoff or Monti's principle) between July 2001 and November 2015 in our department...

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...

OBJECTIVE: Intravesical BCG therapy is widely used for the treatment of high-risk, non-muscle-invasive bladder cancer. Among various reported side-effects, decreased bladder capacity is a serious side-effect that significantly worsens patients' quality of life. This article reports the efficacy and safety of bladder hydrodistension (BHD) in six patients with seriously decreased bladder capacity caused by BCG treatment. METHODS: Six patients with low bladder capacity (<100 ml in voiding diaries) and complaint of grade 3 irritative symptoms were diagnosed with decreased bladder capacity and treated with BHD...

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...
