1. VI-RADS score system - A primer for urologists
ABSTRACT Bladder cancer (BCa) is one of the most common cancers worldwide and is also considered to be one of the most relapsing and aggressive neoplasms. About 30% of patients will present with muscle invasive disease, which is associated with a higher risk for metastatic disease. The aim of this article is to review the state of art imaging in Radiology, w

2. The association between the histopathological features and microsatellite instability in young patients with urothelial carcinoma of the bladder
SUMMARY OBJECTIVE: Bladder cancer under the age of 40 is extremely rare. Bladder cancer development involves complex and multi-stage processes, one of which is the DNA damage repair mechanism. In this retrospective study, we aimed to evaluate the histopathological features of bladder urothelial carcinoma seen in patients under 40 years of age and tumor micr

3. Non-functional paraganglioma of urinary bladder managed by transurethral resection
ABSTRACT Purpose As a rare bladder tumor, paraganglioma of the urinary bladder (PUB) is frequently misdiagnosed as bladder cancer, particularly for the non-functional type. To date, transurethral resection remains a controversial treatment for non-functional PUB. This study aimed to identify the clinical features, pathological characteristics, prognosis, a

4. Absence of TERT promoter mutations in colorectal precursor lesions and cancer
Abstract Hotspot mutations (c.-124bp G > A and c.-146bp G > A) in the promoter region of the TERT gene have been recently described in several types of solid tumors, including glioma, bladder, thyroid, liver and skin neoplasms. However, knowledge with respect to colorectal precursor lesions and cancer is scarce. In the present study we aimed to determine the

5. Overexpression of UHRF1 gene correlates with the major clinicopathological parameters in urinary bladder cancer
ABSTRACT Introduction Recently, expression of the UHRF1 gene was found to be up-regulated in numerous neoplasms, including the urinary bladder transitional cell carcinoma (TCC). Objective The aim of our study was to determine if the expression levels of UHRF1 gene correlates with the major pathological characteristics of the tumor and patients’ clinica

6. Urothelial neoplasm of the bladder in childhood and adolescence: a rare disease
ABSTRACT Purpose: Bladder tumors are rare in children and adolescents. For this reason, the diagnosis is sometimes delayed in pediatric patients. We aimed to describe the diagnosis, treatment, and follow-up methods of bladder urothelial neoplasms in children and adolescents. Materials and Methods: We carried out a retrospective multicenter study involving

7. Low grade urothelial carcinoma mimicking basal cell hyperplasia and transitional metaplasia in needle prostate biopsy
ABSTRACT Purpose The vast majority of urothelial carcinomas infiltrating the bladder are consistent with high-grade tumors that can be easily recognized as malignant in needle prostatic biopsies. In contrast, the histological changes of low-grade urothelial carcinomas in this kind of biopsy have not been studied. Materials and Methods We describe the clini

8. Cutaneous invasion from sarcomatoid urothelial carcinoma: clinical and dermatopathologic features
Abstract In Brazil, without considering the non-melanoma skin tumors, bladder cancer in men is the eighth most common, and the urothelial carcinoma or transitional cell carcinoma is the most common among these. Cutaneous metastases from urothelial neoplasms appear as single or multiple erythematous, infiltrated nodules or plaques, and like other cases of dis

9. Análise de expressão de micro RNA em carcinoma urotelial de bexiga / Analysis of micro RNA expression in bladder urothelial carcinoma
Introduction: Bladder cancer (BC) is the second most common malignancy of the urinary tract, with 386,000 cases estimated and 150,000 deaths in 2011. Urothelial carcinomas (UC) represent 95% of BC cases, and knowledge of the molecular pathways associated with BC carcinogenesis is crucial to identify new diagnostic and prognostic biomarkers, and development o

10. Análise da expressão das metaloproteinases 2 e 9 e seus reguladores no câncer de bexiga / Expression of metalloproteinases 2 and 9 and their regulator genes in bladder cancer
Introdução: O Carcinoma Urotelial de Bexiga (CUB) é o segundo tumor urológico mais prevalente no Brasil. Devido ao elevado custo médico no processo que envolve seu diagnóstico, tratamento e seguimento, o CUB é um dos tipos de tumores mais caros para os sistemas de saúde. Embora existam fatores prognósticos definidos, como o estadiamento patológico,

11. Endoscopic ultrasound-guided biopsies for mediastinal lesions and lymph node diagnosis and staging
OBJECTIVES: To disseminate transesophageal ultrasound-guided fine needle aspiration (EUS-FNA) as an alternative to investigate mediastinal tumoral lesions because it is an underused modality that has been available in Brazil for more than 15 years. METHODS: Descriptive analysis of a single endoscopy service's experience since 1997 in the accomplishment of EU

12. Effects of curcumin in an orthotopic murine bladder tumor model
Cigarette smoking (CS) is the main risk factor for bladder cancer development. There are more than 100 carcinogens present in cigarette smoke. Among the potential mediators of CS-induced alterations is nuclear factor-kappa (NF-κB), which is responsible for the transcription of genes related to cell transformation, tumor promotion, angiogenesis, invasion and
