Objective: Transitional cell carcinoma (TCC) is the most common malignant tumour of the canine urinary tract. Previously, the mutation of the BRAF gene V595E was identified in approximately 85 % of canine TCC cases by DNA sequencing of TCC tumour cells, both in frozen and paraffin-embedded tissue sections, as well as in urine. The objective of this study was to establish these methods in cytological smears and to investigate the prevalence of BRAF mutation V595E in canine TCC in our cohort of patients. Read More

Purpose Of Review: Bladder cancer care is costly due to long surveillance periods for non-muscle-invasive bladder cancer (NMIBC) and comorbidities associated with the surgical treatment of muscle-invasive bladder cancer (MIBC). We reviewed current evidence-based practices and propose quality metrics for NMIBC and MIBC.
Recent Findings: For patients with NMIBC, we propose four categories of candidate quality metrics: (1) appropriate use of imaging, (2) re-staging transurethral resection of bladder tumor, (3) perioperative intravesical chemotherapy, and (4) induction and maintenance BCG in high-risk NMIBC.

Background: Epithelioid angiomyolipoma is defined as potentially malignant mesenchymal neoplasm, characterized by proliferating epithelioid cells, whereas classic angiomyolipoma, composed of fat, smooth muscle cells and dysmorphic vessels, is defined as a potentially benign. The usual or classic angiomyolipoma is often found incidentally on imaging studies, relatively easily identified due to the presence of fat, in contrast to the epithelioid angiomyolipoma that can pose diagnostic challenges.
Case Presentation: We report a 51-year-old female patient in which an ultrasonography examination showed a solid mass close to the right renal pelvis with hypoechoic and hyperechoic areas. Read More

Until recently, there were no true innovations in the management of locally advanced (aUC) and metastatic urothelial cancer (mUC) in the last three decades. Vinflunine has been approved by the EMA (European Medicines Agency) with only limited improvement compared to best supportive care in second line treatment. In addition, gemcitabine/cisplatin has been established as an alternative to methotrexate, vinblastine, doxorubicin, and cisplatin (MVAC). Read More

Rationale: Solitary extramedullary plasmocytoma may arise in any organ, either as a primary tumor or as part of a systemic myeloma; if it rarely affects bladder, it presents with urinary symptoms. We describe the first case of asymptomatic BP occasionally diagnosed in a patient with ascites.
Patient Concerns: A 74-year-old woman with hepatitis C virus (HCV)-related liver cirrhosis presented with ascites and no urinary or other symptoms. Read More

Transitional cell carcinoma of the bladder is particularly devastating due to its high rate of recurrence and difficulty in retention of treatments within the bladder. Current cystoscopic approaches to detect and stage the tumor are limited by the penetrative depth of the cystoscope light source, and intravesical dyes that highlight tumors for surgical resection are non-specific. To address the needs for improved specificity in tumor detection and follow-up, we report on a novel technology relying on the engineered core of mesoporous silica (MSN) with surface modifications that generate contrast in fluorescence and magnetic resonance imaging (MRI).

Renal cell carcinomas (RCCs) account 80-85% of all primary renal neoplasms and originate from the renal cortex. The patients who underwent radical or partial nephrectomy for renal tumour in our unit between January 2005 and 2015 were evaluated retrospectively. The patients were divided into two groups; group 1 includes patients who were treated between January 2005 and December 2009, group 2 those from January 2010 to 2015. Read More

Purpose: High risk upper tract urothelial carcinoma has been associated with poor survival outcomes. Limited retrospective data support neoadjuvant chemotherapy prior to radical nephroureterectomy. To validate prior findings we evaluated differences in the pathological stage distribution in patients with high risk upper tract urothelial carcinoma based on the administration of neoadjuvant chemotherapy before radical nephroureterectomy.

Objective: We aimed to assess the diagnostic accuracy of C-11 choline and C-11 acetate positron emission tomography/computed tomography (PET/CT) for lymph node (LN) staging in bladder cancer (BC) patients through a systematic review and meta-analysis.
Methods: The MEDLINE, EMBASE, and Cochrane Library database, from the earliest available date of indexing through June 30, 2017, were searched for studies evaluating the diagnostic performance of C-11 choline and C-11 acetate PET/CT for LN staging in BC. We determined the sensitivities and specificities across studies, calculated positive and negative likelihood ratios (LR+ and LR-), and constructed summary receiver operating characteristic curves.

Objective: A highly sensitive and specific urine marker for the detection of recurrent urothelial cancer and for screening healthy population or people at risk for urothelial cancer has not been found yet. As urine cytology is not sensitive enough, patients with non-muscle-invasive bladder cancer need lifelong follow-up involving multiple invasive cystoscopies. Our aims of study were to examine the expression of semaphorin 3A in urothelial cancer patients and to evaluate semaphorin 3A as a potential marker for urothelial cancer. Read More

Accurate detection and staging is critical to the appropriate management of urothelial cancer (UC). The use of advanced optical techniques during cystoscopy is becoming more widespread to prevent recurrent nonmuscle invasive bladder cancer. Standard of care for muscle-invasive UC includes the use of computed tomography and/or magnetic resonance imaging, but staging accuracy of these tests remains imperfect. Read More

Intravesical Bacillus Calmette-Guérin (BCG) immunotherapy decreases the progression risk of non-muscle-invasive bladder cancer, but potentially yields a broad spectrum of side effects. We report the case of a 73-year-old man affected by miliary pulmonary BCG infection, whose microbiological diagnosis was probably hindered by empiric fluoroquinolones, focusing on imaging and clinical work-up.

Background: To study the utility of the laminin immunostain in distinguishing invasive from noninvasive urothelial carcinoma (UC). The distinction is difficult but clinically significant as it can affect the decision to administer intravesical Bacillus Calmette-Guerin or can even lead to cystectomy.
Materials And Methods: Representative sections of the transurethral resection of bladder tumor specimens from 25 cases of formalin-fixed paraffin-embedded invasive UCs and 25 cases of noninvasive UCs were selected for immunohistochemical (IHC) staining with laminin (Ventana, Oro Valley, AZ, USA).
