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)...

Genomic analyses are defining numerous new targets for cancer therapy. Therapies aimed at specific genetic and epigenetic targets in cancer cells as well as expanded development of immunotherapies are placing increased demands on animal models. Traditional experimental models do not possess the collective features (cancer heterogeneity, molecular complexity, invasion, metastasis, and immune cell response) critical to predict success or failure of emerging therapies in humans. There is growing evidence, however, that dogs with specific forms of naturally occurring cancer can serve as highly relevant animal models to complement traditional models...

PURPOSE: Pathologic staging of bladder cancer patients remains a challenge. Standard-of-care histology exhibits limited sensitivity in detection of micrometastases, which can increase risk of cancer progression and delay potential adjuvant therapies. Here, we sought to develop a proof of concept novel molecular approach to improve detection of cancer micrometastasis. EXPERIMENTAL DESIGN: We combined fluorescence activated cell sorting and next-generation sequencing and performed whole-exome sequencing of total cancer cells and cancer cell subpopulations in multiple tumor specimens and regional lymph nodes in a single patient with muscle-invasive urothelial carcinoma of the bladder following radical cystectomy...

AIMS: Pathologic stage T1 (pT1) bladder cancers are a clinically heterogeneous group. However, current staging guidelines for superficially invasive cancers do not acknowledge the variability in type and extent of lamina propria invasion in papillary urothelial carcinomas (PUC), and historically proposed substaging systems showed either high inter-observer variation or limited value in predicting patient outcomes. Herein we reappraise pT1 PUC substaging, aiming to identify a novel scheme which is reproducible and prognostically meaningful...

Although tumors involving the bladder and ureter have been well described, there are only few studies in the pathology literature specifically analyzing tumors involving the ureteral orifice (UO). A search was performed for biopsy and resection specimens (transurethral resection, radical cystectomy/cystoprostatectomy, nephroureterectomy and bladder cuff resection) of urothelial carcinoma (UCa) involving the UO. Ninety three cases were identified. Sixty two (67%) patients were male. Mean patient age was 71years (range: 43-91years)...

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...

High grade mucinous urothelial carcinoma is a rare pathological variant. There is still controversy as to its nomenclature and classification. We report the case of a 64 year old female with history of pelvic pain who was incidentally discovered to have a left upper pole renal mass. Left nephroureterectomy was performed and histopathological examination revealed high grade mucinous urothelial carcinoma. Accurate diagnosis of this distinct pathological entity will allow for better understanding of phenotypic behavior and inform best treatment strategies...

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...

Current knowledge of the molecular mechanism driving tumor budding is limited. Here, we focused on elucidating the detailed mechanism underlying tumor budding in urothelial cancer of the bladder. Invasive urothelial cancer was pathologically classified into three groups as follows: nodular, trabecular, and infiltrative (tumor budding). Pathohistological analysis of the orthotopic tumor model revealed that human urothelial cancer cell lines MGH-U3, UM-UC-14, and UM-UC-3 displayed typical nodular, trabecular, and infiltrative patterns, respectively...

OBJECTIVE: Cytology is recommended as part of the follow-up of high-grade non-muscle-invasive bladder cancer (NMIBC). However, currently there are no solid guideline recommendations regarding the use of voided urine versus bladder washing for cytology as part of the diagnosis or follow-up of NMIBC. The aim of this study was to investigate whether the cytological outcome was equal regarding the two techniques. MATERIALS AND METHODS: The authors reviewed all outpatient flexible cystoscopies carried out in their department in 2013...
