Arsenic exposure is an environmental risk factor for urothelial carcinoma (UC). The natural history of upper tract urothelial carcinoma (UTUC) differs from that of bladder cancer (BC). However, the risk factors of BC and UTUC are not exactly the same and should be discussed separately. The aims of this study were to evaluate 1) the association between arsenic methylation capacity and UTUC and/or BC, separately, and 2) the association between polymorphisms of the arsenic metabolism-related genes AS3MT, GSTOs, and PNP against BC and/or UTUC, separately...

Many controversies exist regarding the appropriate management of patients with upper tract urothelial carcinoma (UTUC), including staging, surgical management, use of systemic therapy and prevention of bladder recurrence. Due to the rarity of this condition, high level evidence is often lacking and in many cases guidelines are extrapolated from existing evidence on urothelial bladder cancer. Areas covered: This review paper summarizes the evidence on proper diagnosis and staging, surgical techniques, prevention of bladder recurrences, the use of local or systemic treatments in both neoadjuvant and adjuvant settings as well as special consideration for hereditary UTUC...

PURPOSE: Topical therapy (TT) for upper tract urothelial carcinoma (UTUC) has been explored as a kidney sparing approach to treat carcinoma in situ (CIS) and as adjuvant for endoscopically treated Ta/T1 tumors. In bladder cancer, data support use of salvage TT for repeat induction. We investigate the outcomes of salvage TT for UTUC in patients ineligible for or refusing nephroureterectomy. METHODS: A single-center retrospective review on patients receiving salvage TT via percutaneous nephrostomy tube or cystoscopically placed ureteral catheters was performed...

PURPOSE: Enhancer of zeste homolog 2 is a methyltransferase encoded by the EZH2 gene, whose role in upper tract urothelial carcinoma (UTUC) is poorly understood. We sought to evaluate the prognostic value of EZH2 expression in UTUC. METHODS: We reviewed a multi-institutional cohort of patients who underwent radical nephroureterectomy for high-grade UTUC from 1990 to 2008. Immunohistochemistry for EZH2 was performed on tissue microarrays. Percentage of staining was evaluated, and the discriminative value of EZH2 was tested, with EZH2 positivity defined as>20% staining present...

Purpose The aim of this work was to investigate the predictive factors for bladder cancer recurrence survival (BCRS) in patients with upper-tract urothelial carcinoma (UTUC). Methods We selected patients with UTUC who underwent segmental ureterectomy (Su) or nephroureterectomy (Nu) from 2004 to 2013 from the Surveillance, Epidemiology, and End Results (SEER) database. Patients with a history of intravesical therapy for bladder cancer and bladder cancer prior to the diagnosis of UTUC were excluded. We used Kaplan-Meier analysis, log-rank tests, and Cox proportional hazards model to compare overall survival, cancer-specific survival, and BCRS...

OBJECTIVE: Bladder cancer recurrence after management of upper tract urothelial carcinoma (UTUC) is a common disease. Although the incidence and risk factors for the development of noninvasive bladder tumor have been reported in many series, rare studies have reported on muscle invasive bladder cancer (MIBC) and its urethral recurrence. We aimed to report the incidence, risk factors and survival rate for the development of MIBC and urethral tumors after surgical management of UTUC. MATERIAL AND METHODS: We retrospectively reviewed patients who were surgically treated for UTUC from 1983 to 2013...

BACKGROUND: There is growing evidence that the transcription factor nuclear factor E2-related factor 2 (Nrf2) is the major participant in regulating antioxidants and pathways for detoxifying reactive oxygen species (ROS), as well as having a vital role in tumor proliferation, invasion, and chemoresistance. It was also recently reported that Nrf2 supports cell proliferation by promoting metabolic activity. Thus, Nrf2 is involved in progression of cancer. Upper urinary tract urothelial carcinoma (UTUC) is a biologically aggressive tumor with high rates of recurrence and progression, resulting in a poor prognosis...

INTRODUCTION: Hematuria is the most common symptom of urothelial carcinomas (UC) but is often idiopathic. Cystoscopy is expensive which involves considerable patient discomfort, and conventional urine cytology for noninvasive UC detection and disease monitoring suffers from poor sensitivity. We aim to evaluate the performance of genes selected from a previous study in detecting UC, especially among patients with gross hematuria, as well as upper tract urothelial carcinoma (UTUC) and bladder carcinoma separately, in voided urine samples...

Purpose: We compared oncologic outcomes of patients with upper tract urothelial carcinoma (UTUC) who underwent open nephroureterectomy (ONU) or laparoscopic nephroureterectomy (LNU). Materials and Methods: Consecutive cases of ONU and LNU between 2000 and 2012 at five participating institutions were included in this retrospective analysis. Clinical characteristics and pathologic outcomes were compared between the two surgical approaches. The influence of the type of surgical approach on intravesical recurrence-free survival (IVRFS), progression-free survival (PFS), cancer-specific survival (CSS), and overall survival (OS) was analyzed using the Kaplan-Meier method and differences were assessed with the log-rank test...

The identification of upper tract urinary carcinoma (UTUC) prognostic biomarkers is urgently needed to predict tumour progression. This study aimed to identify serum microRNAs (miRNAs) that may be useful as minimally invasive predictive biomarkers of tumour progression and survival in UTUC patients. To this end, 33 UTUC patients who underwent radical nephroureterectomy at the Hospital Clinic of Barcelona were prospectively included. Expression of 800 miRNAs was evaluated in serum samples from these patients using nCounter® miRNA Expression Assays...

A select group of patients with upper tract urothelial carcinoma (UTUC) may meet indications for endoscopic management. Strategies for disease management are provided, based on a comprehensive review of the data using PubMed and Medline databases and marrying this with our experience with endoscopic management of UTUC. Endoscopic management of UTUC via retrograde or antegrade approaches is a viable treatment option for appropriately selected patients with low-risk UTUC, including those with low-grade, low-volume, and solitary tumors...

Upper tract urothelial cancer (UTUC) arises from the urothelial lining of the urinary tract. UTUC spreads in several different ways including direct invasion, lymphatic spread, and hematogeneous metastases. Regional lymph nodes are commonly the initial site of metastasis, followed by the liver, lung, and bone. Brain metastasis is uncommon in patients with urothelial carcinoma. Here, we report an uncommon case of kidney urothelial carcinoma with brain metastasis in a 55-year-old woman presenting with dysarthria with right side limb weakness...
