Objective: T1 high-grade bladder cancer has a poor prognosis compared with other non-muscle-invasive bladder cancers. We investigated the clinical outcomes among patients with T1 high-grade bladder cancer to identify factors related to cancer recurrence and disease progression. Methods: We retrospectively reviewed the data of 148 patients who were diagnosed with T1 high-grade bladder cancer by transurethral resection from January 2001 to February 2015 at our institution...

PURPOSE: Bladder preservation therapy is an effective treatment for muscle-invasive urothelial carcinoma (UC). In this study we treated noncystectomy candidates with daily radiation and weekly paclitaxel for 7 weeks. Patients whose tumors showed her2/neu overexpression were additionally treated with weekly trastuzumab. METHODS AND MATERIALS: Sixty-eight evaluable patients were treated with radiation therapy and either paclitaxel + trastuzumab (group 1) or paclitaxel alone (group 2)...

OBJECTIVES: To examine the inhibitory effects of tumor necrosis factor-α on myogenic differentiation of human urethral rhabdosphincter cells. METHODS: A rhabdosphincter sample was obtained from a patient who underwent total cystectomy. To expand the lifespan of the primary cultured cells, rhabdosphincter myogenic cells were immortalized with mutated cyclin-dependent kinase 4, cyclin D1 and telomerase. The differential potential of the cells was investigated. The transfected human rhabdosphincter cells were induced for myogenic differentiation with recombinant human tumor necrosis factor-α and/or the tumor necrosis factor-α antagonist etanercept at different concentrations, and activation of signaling pathways was monitored...

We performed a phase 2 pharmacodynamic, prevention trial of Polyphenon E® (a green tea polyphenol formulation primarily consisting of epigallocatechin gallate (EGCG)) in patients prior to bladder cancer surgery. Patients with a bladder tumor were randomized to receive Polyphenon E® containing either 800 or 1200 mg of EGCG or placebo for 14 to 28 days prior to TURBT or cystectomy. The primary objective was to compare the post-intervention EGCG tissue levels in patients receiving Polyphenon E® as compared to placebo...

A young patient from central Africa presented acute renal insufficiency due to extrinsic compression of the distal ureters by a pelvic mass. After initial medical management, a biopsy revealed poorly differentiated bladder cancer and Schistosoma haematobium eggs embedded in the bladder wall. The initial workup showed evidence of locoregional disease. Radical cystectomy with an incontinent urinary diversion was performed with no complications. Carcinosarcoma of the bladder was diagnosed by pathological analysis of the surgical specimen...

BACKGROUND: Neoadjuvant chemotherapy (NAC) for muscle-invasive bladder cancer (MIBC) provides a small but significant survival benefit. Nevertheless, controversies on applying NAC remain because the limited benefit must be weight against chemotherapy-related toxicity and the delay of definitive local treatment. Therefore, there is a clear clinical need for tools to guide treatment decisions on NAC in MIBC. Here, we aimed to validate a previously reported 20-gene expression signature that predicted lymph node-positive disease at radical cystectomy in clinically node-negative MIBC patients, which would be a justification for upfront chemotherapy...

Hepatic portal venous gas (HPVG) is a rare ominous radiological sign usually indicative of mesenteric ischemia. Increased detection of HPVG has been associated with a growing number of non-ischemic causes. A 64-year-old gentleman following radical cystectomy and neobladder formation developed clinical signs suggestive of bowel obstruction. HPVG was demonstrated on abdominal imaging. Urgent laparotomy revealed no evidence of ischemia. We hypothesize an obstructed neobladder permitted gas to enter the mesenteric circulation...

Cisplatin-based polychemotherapy is still the standard therapy for metastatic urothelial carcinoma, although disease progression is often noted at an early time point even in patients with response. In recent years, cytoreductive surgery has been gaining increasing interest in many tumor entities in the setting of metastatic disease to improve patients outcome, but urothelial carcinoma is not regarded as a candidate for such a multimodal therapy approach. However, several retrospective studies suggest a survival benefit of radical cystectomy and/or metastasectomy for well-selected patients with metastatic urothelial carcinoma...

Undescended ovary is a rare entity and usually presentedas a case report. It is associated with urinary and uterine anomalies. Symptomatic patients are diagnosed during surgery. Most of the patients are asymptomatic and treatment is unnecessary. They are incidentally diagnosed during infertility evaluation and treatment such as ovarian hyperstimulation studies. A 15-year-old female patient presented with the diagnosis of renal cystic massas identifiedduring ultrasonography in another hospital. Abdominal computedtomography image was requested...

PURPOSE: The Cancer Genome Atlas (TCGA) Research Consortium has conducted a comprehensive molecular characterization of invasive bladder cancer (BCa). This open-access dataset has become the critical reference for studying biomarkers and mechanisms of disease in BCa. In order for this data to be considered representative, and to allow comparisons of markers between cohorts, clinicopathologic characteristics of this cohort need to conform to those established for this disease state. The aim of this study was to critically evaluate clinicopathologic characteristics and outcomes of the TCGA BCa cohort in comparison with published cystectomy series...

REVIEW
Daniel P Nguyen, George N Thalmann
Administration of neoadjuvant chemotherapy preceding radical cystectomy in patients with bladder cancer remains a matter of debate. Results of prospective, randomized studies have demonstrated an overall absolute survival benefit of 5% at 5 years, provided cisplatin-based combination regimens are used. Owing to the perception of a modest survival benefit, the medical community has been slow to adopt the use of neoadjuvant chemotherapy. Other reasons for the underuse of neoadjuvant chemotherapy range from patient ineligibility to fear of delaying potentially curative surgery in nonresponders...

BACKGROUND: Mature cystic teratomas are usually found in the ovaries. They are bilateral in 10 to 15% of cases and multiple cystic teratomas may be present in one ovary. The aim of this study is to clarify if development of mature cystic teratomas of the ovaries in a single host is metachronous or due to autoimplant or recurrence. CASE PRESENTATION: We report a woman with bilateral mature cystic teratomas of the ovaries. DNA profiles of these teratomas were investigated via short tandem repeat (STR) analysis and methylation statuses were determined via methylation sensitive multiplex ligation-dependent probe amplification methods...

INTRODUCTION: Interstitial cystitis is a debilitating condition that has a profound effect on quality of life. Although many approaches to treatment have been explored, no consistently effective treatment has been identified. Reconstructive surgery is offered to patients with refractory IC/BPS; however, expert opinion is divided as to whether simultaneous cystectomy is necessary to achieve symptomatic cure. The aim of this study was to report our experience in the surgical management of IC/BPS in a university teaching hospital...

PURPOSE OF REVIEW: In this review, we summarize the core principles in the management of nonmuscle invasive bladder cancer (NMIBC) with an emphasis on new developments that have emerged over the last year. RECENT FINDINGS: NMIBC has a propensity to recur and progress. Risk stratification has facilitated appropriate patient selection for treatment but improved tools, including biomarkers, are still needed. Enhanced cystoscopy with photodynamic imaging and narrow band imaging show promise for diagnosis, risk stratification, and disease monitoring and has been formally recommended this year by the American Urological Association...
