Lynch syndrome is the most common hereditary cancer syndrome, the most common cause of heritable colorectal cancer, and the only known heritable cause of endometrial cancer. Other cancers associated with Lynch syndrome include cancers of the ovary, stomach, urothelial tract, and small bowel, and less frequently, cancers of the brain, biliary tract, pancreas, and prostate. The oncogenic tendency of Lynch syndrome stems from a set of genomic alterations of mismatch repair proteins. Defunct mismatch repair proteins cause unusually high instability of regions of the genome called microsatellites...

To understand the direct link between Cyclin D1, and nuclear factor of activated T cells 2 (NFAT2) and nuclear factor (NF)-κB in arsenic-treated bladder cells, as well as the association between MAPK and NFAT signaling, we determined whether or not the Ca2+ /NFAT pathway is activated in an arsenic-treated normal urothelial cell line and determined the roles of NFAT and NF-κB signals in the regulation of Cyclin D1 expression. The SV-40 immortalized human uroepithelial cell line, SV-HUC-1, was treated with NaAsO2 for 24 h (0, 1, 2, 4, 8, and 10 μM) and 10, 20, 30, and 40 weeks (0 and 0...

The current WHO/ISUP classification and grading system subdivides urothelial tumours into prognostically distinct categories. Understanding the molecular pathways involved in bladder cancer development can improve patient stratification and management. This study aims to investigate the relationship between Snail, Slug and E-cadherin expressions and clinico-pathological features of non-muscle invasive bladder carcinoma (NMIBC). All patients attending the same urological centre from January to May 2002, who were pathologically diagnosed with NMIBC, were enrolled in this longitudinal cohort study...

A 77-year-old man presented with watery, bloody diarrhoea, symptomatic anaemia and signs of sepsis. He was well known to our unit with a history of extensive low-grade urothelial carcinoma involving a solitary kidney. CT performed on admission demonstrated a new finding of renocolic fistula. Due to his multiple medical and surgical comorbidities conservative management was elected. He passed away after 1 year of follow-up.

FGFR gene alterations represent a target for treatment in clinical trials of urothelial carcinoma (UC). Little is known about their prognostic effect in patients with metastatic UC. We analyzed data for 112 patients treated with platinum-based first-line chemotherapy at our center between October 2011 and March 2017 and who were screened for the presence of FGFR mutations or gene fusions within multiple clinical trials with pan-FGFR inhibitors. Centralized targeted exome sequencing analyses were performed to detect multiple FGFR mutations and fusions...

BACKGROUND: A recent study on the comprehensive genomic profile of advanced urothelial bladder cancer (UBC) showed cyclin-dependent kinase inhibitor 2A (CDKN2A) and fibroblast growth factor receptor 3 (FGFR3) as the most often clinically relevant genomic alterations. Therefore, the prognostic role of FGFR3 and CDKN2A/p16 for pT1 UBC was studied. PATIENTS AND METHODS: Clinical data and formalin-fixed paraffin-embedded tissues of pT1 UBC treated with an organ-preserving approach was analyzed retrospectively...

It is rare to see an adult presenting with exstrophy of the bladder. Malignant conversion in exstrophy occurs in 4%, with adenocarcinoma as the most common histopathology. We report the first case of metastatic high grade urothelial carcinoma with squamous and sarcomatoid differentiation arising from undiagnosed, closed bladder exstrophy in a female at advanced age with associated bilateral deep vein thrombosis and clot retention. The patient developed clinical progression of disease despite neoadjuvant gemcitabine-cisplatin and salvage (or palliative) radiotherapy...

INTRODUCTION: To investigate the impact of perioperative factors on overall survival among patients with histologic variants of bladder cancer treated with radical cystectomy. MATERIALS AND METHODS: The National Cancer Data Base was utilized to identify patients diagnosed with muscle-invasive bladder cancer (cT2-4, N0, M0) from 2004-2013. Variant histology bladder cancers (non-mucinous adenocarcinoma, mucinous/signet ring adenocarcinoma, micropapillary urothelial carcinoma, small cell carcinoma, and squamous cell carcinoma) were compared to urothelial carcinoma with respect to overall survival...

INTRODUCTION: To establish if the validated tumor biomarkers of luminal and basal bladder cancers in non neuro-urological patients are applicable to a neuro-urological population. MATERIALS AND METHODS: We retrieved bladder cancer samples from neuro-urological patients (n = 20) and non-neurological controls (n = 40). The expression of GATA3 and CK5/6 was analyzed using immunohistochemistry of microarray tissue sections. We also assessed the correlation between previous biomarker expression, gender, age, tumor stage (non-muscle-invasive bladder cancer (NMIBC)/muscle-invasive bladder cancer (MIBC)), squamous-cell differentiation and basal/luminal subtypes using Pearson's correlation coefficient (r)...

Bladder cancer (BC) is a heterogeneous neoplasia characterized by a high number of recurrences. Standardized clinical and morphological parameters are not always sufficient to predict individual tumor behavior. The aim of this study was to evaluate the expression of cell cycle regulators proteins as potential adjuvant in prognosis and monitoring of this disease. Block paraffin samples from patients with urothelial bladder carcinoma treated by transurethral resection (TUR) were collected to immunohistochemistry analysis for proteins p16, p21, p27, p53, pRb and Ki-67...

Liver cancer is one of the most common malignancies in the world with a leading cause of cancer-related mortality. Accumulating evidences have highlighted the critical role of long noncoding RNAs (lncRNAs) in various cancers. The present study aimed to explore the role of lncRNA urothelial carcinoma associated 1 (UCA1) in cell growth and migration in MHCC97 cells and its underlying mechanism. Firstly, we assessed the expression of UCA1 in MHCC97 and other three cell lines by qRT-PCR. Then, the expression of UCA1, miR-301a and CXCR4 in MHCC97 cells were altered by transient transfection...

BACKGROUND: The non-invasive Cxbladder urine test system has demonstrated clinical utility in ruling out urothelial carcinoma (UC) in patients with asymptomatic microscopic hematuria (AMH), suggesting that the number of invasive diagnostic tests, including cystoscopy, used in this patient population may be reduced by Cxbladder testing prior to conducting a full urological work-up. The aim of this study was to demonstrate the enhanced clinical utility of communicating objective information on diagnostic decisions made by individual physicians on individual patients with AMH...

Bacillus Calmette-Guérin in urothelial carcinoma, high-dose interleukin-2 in renal cell carcinoma, and sipuleucel-T in prostate cancer serve as enduring examples that the host immune response can be harnessed to promote effective anti-tumor immunity in genitourinary malignancies. Recently, cancer immunotherapy with immune checkpoint inhibitors has transformed the prognostic landscape leading to durable responses in a subset of urothelial carcinoma and renal cell carcinoma patients with traditionally poor prognosis...

Using preclinical models, we have recently found that ELK1, a transcriptional factor that activates downstream targets, including c-fos proto-oncogene, induces bladder cancer outgrowth. Here, we immunohistochemically determined the expression status of phospho-ELK1, an activated form of ELK1, in upper urinary tract urothelial carcinoma (UUTUC). Overall, phospho-ELK1 was positive in 47 (47.5%; 37 weak (1+) and 10 moderate (2+)) of 99 UUTUCs, which was significantly ( P = 0.002) higher than in benign urothelium (21 (25...

BACKGROUND: Biomarker-guided clinical trials are increasingly common in metastatic urothelial carcinoma (mUC), yet patients for whom contemporary tumor tissue is not available are not eligible. Technological advancements in sequencing have made cell-free circulating DNA (cfDNA) next-generation sequencing (NGS) readily available in the clinic. The objective of the current study was to determine whether the genomic profile of mUC detected by NGS of cfDNA is similar to historical tumor tissue NGS studies...
