Urothelial carcinoma (UC) is the most common type of cancer of the bladder and upper urinary tract, and is characterized by a high risk of recurrence and progression. Urine fluorescence in situ hybridization (FISH) is a technique that detects genetic aberrations in exfoliated cells in the urine, with specific probes for chromosomes 3, 7 and 17 and the p16 gene. To evaluate the diagnostic value of FISH in UC, 119 patients from November 2010 to June 2012 with suspected UC were recruited into a prospective, cross-sectional study and were followed up for 12-30 months...

Urothelial carcinoma (UC), arising from the urothelium of the urinary tract, can occur in the upper (UTUC) and the urinary bladder (UBUC). A representative molecular aberration for UC characteristics and prognosis remains unclear. Data mining of Gene Expression Omnibus focusing on UBUC, we identified sulfatase-1 (SULF1) upregulation is associated with UC progression. SULF1 controls the sulfation status of heparan sulfate proteoglycans and plays a role in tumor growth and metastasis, while its role is unexplored in UC...

Aristolochic acid (AA) is a bioactive component of Chinese herbs, dietary supplements, slimming pills and contaminated flour, which is known to induce chronic tubulointerstitial disease. AA is also shown to be involved in the genesis of the upper urinary tract urothelial carcinoma (UTUC) and some other cancers, but its tumorigenic role is far to be understood. We performed a systematic literature review regarding the involvement of AA in malignant processes and molecular pathways of carcinogenesis. Twenty representative papers were selected for this review...

Upper tract urothelial carcinoma is a relatively uncommon malignancy. The gold standard treatment for this type of neoplasm is an open radical nephroureterectomy with excision of the bladder cuff. This systematic review compares the perioperative and oncologic outcomes for the open surgical method with the alternative surgical management options of laparoscopic nephroureterectomy and robot-assisted nephroureterectomy (RANU). MEDLINE, EMBASE, PubMed, and Cochrane Library databases were searched using a sensitive search strategy...

The neutrophil-to-lymphocyte ratio (NLR) is an inflammation marker that has prognostic value for various tumors, but its prognostic value in urothelial carcinoma (UC) remains controversial. This meta-analysis investigated the prognostic value of NLR in UC. A systematic search was performed on PubMed, ISI Web of Science, and Embase for studies focusing on the association between NLR and clinical features or prognosis of UC and published until November 2016. Prognostic outcomes and clinical features were collected and analyzed...

Upper urinary tract urothelial carcinoma exhibiting variant morphology, especially in higher-grade tumors, is a recognized phenomenon but has not been comparatively studied in biopsy versus resection material. We studied the morphologic patterns and clinicopathological features, and provide a comparison between biopsy and resection specimens. Consultation cases were evaluated separately to investigate for possible consultation bias. A total of 383 in-house cases from 352 patients including 314 resection specimens and 69 biopsies from 2001-2014 were reviewed from a single institution...

BACKGROUND: The role of lymph node dissection (LND) for upper tract urothelial carcinoma (UTUC) patients remains controversial. The aim of this study was to evaluate the effect of LND on clinical outcomes during radical nephroureterectomy (RNU) and to determine prognostic factors of survival. PATIENTS AND METHODS: From 1985 to 2013, 404 patients with UTUC underwent RNU; 5 patients who received neoadjuvant chemotherapy were excluded. Among them, 182 (46%) were pathologically negative for lymph node metastasis (pN0), 177 (44%) were non-LND (pNx), and 40 (10%) were positive for lymph nodes metastasis (pN1/2)...

PURPOSE: Recently, several studies have shown that the De Ritis ratio (aspartate transaminase/alanine transaminase) can be a useful prognostic biomarker for certain types of malignant tumors. However, the prognostic value of the De Ritis ratio in patients with upper tract urothelial carcinoma remains largely unknown. The aim of the present study was to evaluate the prognostic significance of the De Ritis ratio in patients who had undergone radical nephroureterectomy (RNU) for upper urinary tract urothelial carcinoma...

Radical nephroureterectomy with an ipsilateral bladder cuff is the referent standard for management of muscle-invasive, high-grade, or bulky upper-tract urothelial carcinoma (UTUC). Nonetheless, certain patients with UTUC have imperative or elective indications for kidney preservation thereby lending to more conservative strategies for management of this disease. Areas covered: A review of the PubMED and Medline databases was performed to identify original scientific and review articles discussing retrograde ureteroscopic or percutaneous antegrade resection of UTUC tumors published between 1995 and 2016...

Port Site Recurrence (PSR) following laparoscopic tumor resections has been reported for a variety of tumors. Though PSR is a rare phenomenon, they most commonly occur following nephroureterectomies for upper tract urothelial carcinoma. Herein we report a novel case of a PSR following a robotic assisted nephroureterectomy for the sarcomatoid variant of urothelial carcinoma of the upper urinary tract.

In this report, we summarized the clinicopathologic features of ten cases of lymphoepithelioma-like carcinoma (LELC) of the upper urinary tract (ureter n = 6; renal pelvis n = 4), a rare variant of urothelial cancer characterized by a malignant epithelial component densely infiltrated by lymphoid cells. The initial diagnosis was made on radical nephrectomy in five cases, nephroureterectomy in three cases, and ureterectomy in two others. Four patients had pathologic stage T1 (n = 2) or T2 (n = 2) tumors, and six patients had stage pT3 disease...

Immunohistochemistry of a transcription factor, GATA3, has been widely used as a promising urothelial marker in diagnostic surgical pathology practice. However, the expression status of GATA3 in upper urinary tract urothelial carcinomas (UUTUCs) and its prognostic significance have not been fully investigated. We immunohistochemically stained for GATA3 in 99 UUTUC samples and paired non-neoplastic urothelial tissues. GATA3 was positive in 51 [51.5%; 32 (32.3%) weak, 11 (11.1%) moderate, 8 (8.1%) strong] of 99 UUTUCs, which was significantly lower than in benign urothelium [79 (96...

This study is to clarify the prognostic value of preoperative plasma fibrinogen and serum albumin level, as known as FA score, in a cohort of Chinese patients with upper urinary tract urothelial carcinoma (UTUC). We retrospectively evaluated clinicopathological data on 169 patients who underwent surgery between 2006 and 2013. The FA score was calculated based on cutoff values of 3.53g/L for fibrinogen and 43.56 g/L for albumin. Overall survival and cancer specific survival was assessed using the Kaplan-Meier method and the equivalences of the curves were tested by log-rank tests...
