An 87-year-old-man with prostate-cancer-stage-T1c-Gleason-6 treated with radiotherapy in 1996, recurrent prostate cancer treated with leuprolide hormonal therapy in 2009, and bladder-urothelial-carcinoma in situ treated with Bacillus-Calmette-Guerin and adriamycin in 2010, presented in 2015 with painless, bright red blood per rectum coating stools daily for 5 mo. Rectal examination revealed bri...

B7-H4 is a recently identified member of the B7 family considered to negatively regulate the immune response, and has been associated with the occurrence and development of certain types of tumor. However, little is known regarding the importance of human B7-H4 expression in bladder urothelial carcinoma. In the present study, B7-H4 expression in the tissues and sera of patients with bladder uro...

OBJECTIVE Fatty acid synthase has been shown to be highly expressed in various types of cancers with increased tumour aggressiveness. In this study we examined the level of fatty acid synthase expression in surgically resected upper urinary tract urothelial carcinoma specimens and evaluated the relations between fatty acid synthase expression and the patients' pathological features and clinical...

OBJECTIVES To evaluate the pathologic findings and outcomes after distal ureterectomy for a retained ureteral segment following incomplete nephroureterectomy for urothelial carcinoma of the renal pelvis or ureter. MATERIALS AND METHODS After IRB approval, an institutional database identified patients who underwent distal ureterectomy for a retained ureteral segment after assumed complete neph...

BACKGROUND DNA methylation aberration and microRNA (miRNA) deregulation have been observed in many types of cancers. A systematic study of methylome and transcriptome in bladder urothelial carcinoma has never been reported. METHODOLOGY/PRINCIPAL FINDINGS The DNA methylation was profiled by modified methylation-specific digital karyotyping (MMSDK) and the expression of mRNAs and miRNAs was ana...

Visfatin, a newly discovered adipocytokine, is a pro-inflammatory cytokine. This study aimed to evaluate the predictive value of visfatin on prognosis of patients with upper tract urothelial carcinoma. One-hundred and five patients (median age=64, range=24-84 years) were included in this study. Visfatin expression in upper tract urothelial carcinoma tissues was analyzed by immunohistochemistry....

The incidence for bladder urothelial carcinoma, a common malignancy of the urinary tract, is about three times higher in men than in women. Although this gender difference has been primarily attributed to differential exposures, it is likely that underlying biologic causes contribute to the gender inequality. In this study, we report a transgenic mouse bladder tumor model upon induction of cons...

The purpose of this study was to determine the relationship between hypermethylation of DACT1 gene promoter and lower mRNA expression in bladder urothelial carcinoma tissue. The methylation status of 29 urothelial carcinoma samples and 29 normal tissue samples were examined by methylation-specific polymerase chain reaction (MSP). The DACT1 mRNA transcript levels and DACT1 protein levels in all ...

Anterior gradient 2 (AGR2) is a cancer-associated secreted protein found predominantly in adenocarcinomas. Given its ubiquity in solid tumors, cancer-secreted AGR2 could be a useful biomarker in urine or blood for early detection. However, normal organs express and might also secrete AGR2, which would impact its utility as a cancer biomarker. Uniform AGR2 expression is found in the normal bladd...

UNLABELLED Urothelial carcinoma is a disease at high risk of recurrence after the initial therapy (70-80%) and with the tendency to progression accomplishing the recurrence (30%). Long lasting monitoring of patients with urothelial carcinoma is necessary. Cystoscopy and cytology are currently the primary modalities used to detect and monitor urothelial carcinoma. However, cytology has relativel...
