The tumour immune microenvironment is considered to influence cancer behaviour and outcome. Using a panel of markers for innate and adaptive immune cells we set out to characterise and understand the bladder tumour microenvironment of 114 patients from a prospective multicentre cohort of newly-diagnosed bladder cancer patients, followed-up for 4.33±1.71 years. We found IL-17-positive cells were significantly increased in primary and concomitant carcinoma in situ (CIS), p<0.0001, a highly malignant lesion which is the most significant single risk factor for disease progression...

BACKGROUND: The aim of this study was to revise the histopathologic types of neoplasias in the genitourinary tract and determine the frequency of 2 new entities included in the 2016 book of World Health Organization classification of renal tumors. It is not established so far whether these 2 recently described tumors are the most frequent in association with end-stage kidney disease. METHODS: In a retrospective analysis, we revised the histopathologic type of 37 genitourinary tumors from 21 patients in dialysis and/or submitted to renal transplantation from 2003 to 2016 aiming to find the frequency of acquired cystic disease-associated renal cell carcinoma and clear cell papillary (tubulopapillary) renal cell carcinoma...

We performed a comprehensive immuno-genomic analysis of tumor microenvironment immune types (TMITs), which is classified into four groups based on PD-L1+CD8A or PD-L1+cytolytic activity (CYT) expression, across a broad spectrum of solid tumors in order to help identify patients who will benefit from anti- PD-1/PD-L1 therapy. The mRNA sequencing data from The Cancer Genome Atlas (TCGA) of 14 solid cancer types representing 6,685 tumor samples was analyzed. TMIT was classified only for those tumor types that both PD-L1 and CD8A/CYT could prefict mutation and/or neoantigen number...

Objective: The rate of intravesical recurrence after radical nephroureterectomy for upper urinary tract urothelial carcinoma is high. Seeding upper urinary tract urothelial carcinoma cells onto the damaged bladder wall is considered to be one of the causes of intravesical recurrence after radical nephroureterectomy. We evaluated the utility of early ureteral ligation in preventing the intravesical recurrence. Methods: This prospective single-arm clinical trial included patients who underwent radical nephroureterectomy for upper urinary tract urothelial carcinoma in the Tohoku Urological Evidence-Based Medicine Study Group between 2012 and 2013...

INTRODUCTION: Knowledge of the comparative oncologic outcomes of histologic variants after radical cystectomy (RC) for muscle-invasive bladder cancer (MIBC) relies on small case series. We compared the effect of pure squamous cell carcinoma, adenocarcinoma, and neuroendocrine carcinoma compared with pure urothelial carcinoma (PUC) on overall survival (OS) and pathologic tumor, lymph node, and surgical margin status after RC. PATIENTS AND METHODS: Using the National Cancer Database, we retrospectively examined patients undergoing RC for MIBC from 2003 to 2011...

Primary malignancies of female urethra are infrequent, constituting a fraction of less than 1% of genitourinary malignancies. Primary clear-cell adenocarcinoma of the urethra, is even rarer, that histomorphologically resembles clear-cell carcinoma of the female genital tract, occurs predominantly in women and is associated with a relatively poor prognosis. The histogenesis of this rare urethral neoplasm has not been completely determined. Various hypotheses concerning the origin have been postulated, including (1) diverticular origin (2) mullerian origin (3), glandular differentiation of urothelium or urothelial carcinoma...

The epidermal growth factor receptor (EGFR) family of receptor tyrosine kinases (RTK) consists of four members: EGFR1/ErbB1/HER1, ErbB2/HER2, ErbB3/HER3, and HER4/ErbB4. Signaling through these receptors regulates many key cellular activities, such as cell division, migration, adhesion, differentiation, and apoptosis. The ErbB family has been shown to be overexpressed in different types of cancers and is a target of several inhibitors already in clinical trials. ErbB3 lacks a functional tyrosine kinase domain and therefore has not been as extensively studied as the other members of this family, but its importance in activating downstream pathways, such as the PI3K/Akt pathway, makes this RTK a worthy investigation target, especially in urothelial carcinoma where the PI3K/Akt pathway is vital for progression...

Urine is emerging as a biological fluid suitable to perform liquid biopsy in a minimally invasive manner, a fundamental attribute for prevention and early detection of cancer. Urine biomarkers can be analyzed in voided urine, in urine sediment, and urine supernatant. In the case of urothelial carcinoma, in which tumor cells are in direct contact with urine, the assessment of the levels of biomarkers in the urinary cell fraction appears to be the most promising approach to identify diagnostic and prognostic biomarkers in a noninvasive way...

Cancer stem cells are defined as a self-renewing and self-protecting subpopulation of cancer cells able to differentiate into morphologically and functionally diverse cancer cells with a limited lifespan. To purify cancer stem cells, two basic approaches can be applied, the marker-based approach employing various more of less-specific cell surface marker molecules and a marker-free approach largely based on various self-protection mechanisms. Within the context of urothelial carcinoma, both methods could find use...

Members of the APOBEC3 (A3) family of enzymes were shown to act in an oncogenic manner in several cancer types. Immunodetection of APOBEC3A (A3A), APOBEC3B (A3B), and APOBEC3G (A3G) proteins is particularly challenging due to the large sequence homology of these proteins and limited availability of antibodies. Here we combine independent immunoblotting with an in vitro activity assay technique, to detect and categorize specific A3s expressed in urothelial bladder cancer and other cancer cells.

Molecular subtypes of bladder cancer (BC) can be determined by relatively small immunohistochemistry panels both for non-muscle invasive (NMI) and muscle invasive (MI) tumors. For analysis of NMI tumors, as few as two markers are needed, although classification is dependent also on pathological grade and histological evaluation. The result is a classification into the three tumor-cell phenotypes of NMI-BC, Urothelial-like (Uro), Genomically Unstable (GU), and Basal/SCC-like. For analysis of MI tumors, 13 markers are needed...

Immunohistochemistry is a standard method in histopathology and enables the localized detection of proteins in histological tissue sections. Specific antibodies are bound to cellular antigens, captured by secondary antibodies or polymers, linked to enzymes and visualized by chromogenic substrates. Here, we describe an automated staining technique for larger slide batches as well as a manual protocol for only few slides using a polymer technique. We focus on differentiation markers, measures of cell proliferation, and therapeutic targets in benign and malignant urothelial tissues...

Urothelial carcinoma of the bladder is one of the most common malignancies in the industrialized world, mainly caused by smoking and occupational exposure to chemicals. The favorable prognosis of early stage bladder cancer underscores the importance of early detection for the treatment of this disease. The high recurrence rate of this malignancy also highlights the need for close post-diagnosis monitoring of bladder cancer patients. As for other malignancies, aberrant DNA methylation has been shown to play a crucial role in the initiation and progression of bladder cancer, and thus holds great promise as a diagnostic and prognostic biological marker...
