OBJECTIVE: To evaluate the impact of pneumoperitoneum time on intravesical recurrence (IVR) in upper tract urothelial carcinoma (UTUC) patients who underwent laparoscopic radical nephroureterectomy (LRNU). PATIENTS AND METHODS: We identified 129 UTUC patients who underwent LRNU at our three institutions from 2004 to 2014. We evaluated the association of IVR rate and patient clinico-pathological characteristics including operation time. By retrospectively reviewing all videotapes, we defined pneumoperitoneum time as being from the infusion of pressurized CO2 gas with a pressure of 10-12 mmHg to extirpation of the kidney...

Few histological data are known about patients with a first diagnosis of bladder cancer (BC) at the age ≥80 years. We describe the largest series in this patient group and their distinctive histological features. This unicentric retrospective study included patients at the age ≥80 years with a first diagnosis of bladder cancer between 2005 and 2015. All diagnosis was made by one senior uropathologist according to the WHO 2016 classification, pTNM 7th edition 2009. We examined samples of 185 patients, sex ratio M:W = 2...

An ectopic kidney is a common congenital anomaly of the urogenital system, but malignant tumor in an ectopic kidney has been rarely reported. We report a case of ureteral carcinoma arising from an ectopic kidney in an 83-year-old male. He visited a hospital complaining of gross hematuria. Computed tomography revealed right ectopic kidney, right ureteral tumor and bladder tumor around the right ureteral orifice. Transurethral resection of the bladder tumor was performed and histopathological diagnosis was urothelial carcinoma...

Accurate characterization of renal masses is essential for ensuring appropriate management. Low T2 signal intensity is a common feature of papillary renal cell carcinoma and fat-poor angiomyolipoma. Nonetheless, other types of renal cell carcinoma, oncocytoma, hemangioma, lymphoma, leiomyoma, and urothelial cell carcinoma also can show low signal intensities on T2-weighted imaging (T2WI). Histopathologic features that can lead to low T2 signal intensities in renal tumors include smooth muscle component, papillary architecture, a high nucleus-to-cytoplasm ratio, and hemorrhage...

INTRODUCTION: This study aimed to evaluate whether lymphovascular invasion (LVI) can replace lymph node (LN) involvement as a prognostic marker in patients who do not undergo lymph node dissection (LND) during surgery in patients with upper tract urothelial carcinoma (UTUC). METHODS: A total of 505 patients who underwent radical nephroureterectomy (RNU) were recruited from four academic centres and divided into four groups: node negative (N0, Group 1); node positive (N+, Group 2); no LND without LVI (NxLVI-, Group 3); and no LND with LVI (NxLVI+, Group 4)...

Non-transitional cell carcinomas (non-TCC) of the upper urinary tract as squamous cell carcinoma (SCC), adenocarcinoma, and small cell carcinoma (SmCC) are rare with few case reports in the literature. We retrospectively reviewed our patients who surgically treated for upper tract urothelial carcinoma from 1983 to 2013 for non-TCC pathological cancer characteristics and survival. Among 305 patients, only 5 (1.6%) cases were found: One case of SmCC, another had adenocarcinoma, and 3 SCC cases. None of them had intravesical recurrence and the cancer-specific survival for non-TCC cohort is markedly decreased (log-rank = 0...

Global mRNA expression analysis is efficient for phenotypic profiling of tumours and has been used to define molecular subtypes for almost every major tumour type. A key limitation is that most tumours are communities of both tumour and non-tumour cells. This problem is particularly pertinent when analysing advanced invasive tumours, known to induce major changes and responses in both the tumour and the surrounding tissue. To identify bladder cancer tumour-cell phenotypes and compare classification by tumour-cell phenotype with classification by global gene expression analysis, we analysed 307 advanced bladder cancers (cystectomised) both by genome gene expression analysis and by immunohistochemistry using antibodies for 28 proteins...

The existence of a link between urinary schistosomiasis (US) and bladder carcinoma was first suspected by C. Goebel in 1905. In 1911, A.R Ferguson, who was a professor of Pathology and Microbiology at the Faculty of Medicine in Cairo, published a more detailed survey from 40 autopsies, and reported a likely association of bladder carcinoma with granulomas caused by US. Subsequently, published results from several studies reinforced Ferguson's hypothesis. Moreover, in most countries where US was endemic, association of high prevalence of bladder carcinoma with US had been pointed out...

Upper tract urothelial carcinoma (UC) is an uncommon tumor. Ectopic kidney is also a rare entity. The combination of these two conditions is very rare. A 49-year-old male complained of right flank pain with hematuria. On CT scan he was found to have a malrotated right kidney with soft tissue seen in the upper calyceal group and a normal left kidney. Diagnostic cystoscopy was unremarkable. Radical nephroureterectomy with bladder cuff excision was performed. Pathology report revealed low grade urothelial carcinoma...

A 73-year-old male underwent transurethral resection of a bladder tumor in August 2010 and April 2011. Pathological examination revealed urothelial carcinoma. After the surgery, chemotherapy and intravesical Bacillus Calmette-Guerin instillation were performed. In September 2014, he once again underwent transurethral resection of the bladder tumor for recurrence, and was again diagnosed with urothelial carcinoma, pT2, by pathological examination. After neoadjuvant chemotherapy, radical cystectomy for tumor recurrence was performed...

PURPOSE: To determine major risk factors for bladder cancer (BC) recurrence after nephroureterectomy (Nux) by focusing on the pathologic appearances of tumors in upper urinary tract urothelial carcinomas (UUTUCs). METHODS: We performed 147 Nux procedures between November 2002 and September 2015. Forty-eight patients were excluded because of a history of BC (28 patients), previous or concurrent radical cystectomy (9 patients), neoadjuvant chemotherapy (5 patients), and other reasons (6 patients)...

Purpose There is limited evidence to support the use of adjuvant chemotherapy (AC) after radical nephroureterectomy (RNU) for upper tract urothelial carcinoma (UTUC). Against this backdrop, we hypothesized that such treatment is associated with overall survival (OS) benefit in patients with locally advanced and/or positive regional lymph node disease. Patients and Methods Within the National Cancer Database (2004 to 2012), we identified 3,253 individuals who received AC or observation after RNU for pT3/T4 and/or pN+ UTUC...

INTRODUCTION: Evidence for the use of perioperative chemotherapy (PC) in upper tract urothelial carcinoma (UTUC) is largely derived from level I evidence for invasive urothelial carcinoma of the bladder (UCB). There has been an increase in PC for urothelial carcinoma of the bladder, as it has disseminated into clinical practice. Therefore, we sought to not only analyze trends in the utilization of PC in UTUC, but also assess factors associated with its use in a large cancer registry database...

BACKGROUND: Carcinoma in situ (CIS) is a poor prognostic finding in urothelial carcinoma. However, its significance in muscle-invasive urothelial carcinoma (MIUC) treated with neoadjuvant chemotherapy (NAC) is uncertain. We assessed the effect of CIS found in pretreatment transurethral resection of bladder tumor (TURBT) biopsies on the pathologic and clinical outcomes. MATERIALS AND METHODS: Subjects with MIUC treated with NAC before cystectomy were identified. The pathologic complete response (pCR) rates stratified by TURBT CIS status were compared...
