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...

Introduction: Immunological pathways are relevant for the effectiveness of conventional cytotoxic chemotherapy. Recently, checkpoint inhibition of the PD-1/PD-L1 axis has been shown to be therapeutically relevant in urothelial carcinoma. Objective: To monitor PD-L1 expression on tumor cells and intratumoral infiltration with CD8 positive lymphocytes during perioperative chemotherapy for urothelial cancer and to evaluate their use as potential predictive markers for chemotherapy. Patients and Methods: Sixty-four patients with muscle-invasive urothelial cancer were included in the analysis...

Urothelial tumors are very rare in children (to date, only about 150 cases have been reported worlwide). Only 20 % occur before the age of ten. The aim of this study is to specify the clinicopathologic features of urothelial tumor in young patients, which require a slightly different approach to treatment. On the basis of the WHO/ISUP (World Health Organisation/International Society of Urological Pathology) consensus classification report, these lesions are usually low-grade lesions, non invasive, and rarely recurrent...

The present study reports a rare case of bladder cancer that caused Trousseau's syndrome, a malignancy-associated hypercoagulative state leading to venous or arterial thrombosis. A 38-year-old Japanese female patient experienced a sudden onset of visual field defects and lower limb weakness. Cerebral magnetic resonance imaging revealed multi-regional hypointense areas compatible with acute cerebral infarction. Despite the repeated administration of anticoagulant treatment with heparin, the condition could not be adequately controlled and thromboembolic events occasionally recurred...

Invasive urothelial (transitional cell) carcinoma (UC) is the most common cancer in the canine urinary tract. Prolonged survival of dogs with UC due to better management of the primary tumor and prevention of urethral obstruction might have contributed to an apparent increase in distant metastasis. Metastasis to bone is particularly concerning because the ensuing pain often leads to euthanasia; however, little is known of the frequency, site, or nature of UC skeletal metastasis. In a retrospective analysis, 17 (9%) of 188 canine UC cases had histologically confirmed skeletal metastasis, mainly to the vertebrae...
