1. 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

2. 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

3. 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

4. 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

5. 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,

6. Desequilibrio entre alfa distroglicana (alfa-DG) e metaloproteinase de matriz 9 (MMP-9) no carcinoma urotelial da bexiga e do trato urinario superior : um novo modelo animal / Alph dystroglycan (alfa-DG) and matrix metalloproteinase 9 (MMP-9) imblance on bladder and upper urinary tract uruthelial carcinoma : a new animal model
A destruição do complexo da distroglicana dependente da metaloproteinase da matriz pode ter papel importante no desenvolvimento e progressão do tumor urotelial. O carcinoma urotelial humano é frequente na bexiga e menos comum no trato urinário superior. Não há um modelo experimental animal bem definido e reprodutível de carcinoma urotelial do trato s

7. Cistectomia radical laparoscópica com reservatório ileal
Worldwide experience with laparoscopic radical cystectomy is increasing in the last few years. We describe a 29-year-old female who underwent a laparoscopic radical cystectomy with ileal reservoir for a bladder sarcoma. Operative time was 405 minutes and estimated blood loss was 500 mL. She had an uneventful postoperative course and was discharged in the fif

8. Avaliação do bacilo de Calmette-Guérin recombinante expressando o antígeno S1PT no tratamento do carcinoma urotelial de bexiga em modelo experimental / Evaluation of recombinant bacillus Calmette-Guérin expressing S1PT in the treatment of urothelial bladder carcinoma in an experimental model
Introdução: A imunoterapia intravesical com o bacilo de Calmette-Guérin (BCG) é o tratamento adjuvante de escolha no câncer superficial de bexiga. Recentemente, os estudos do mecanismo imunoterápico do BCG têm permitido identificar as reações imunológicas e os genes associados ao efeito antitumoral, possibilitando a produção de vacinas recombinan

9. Molecular study of cellular adhesion genes in bladder cancer / Estudo molecular de genes envolvidos com adesão celular em câncer de bexiga
Introduction: Bladder cancer is the fifth neoplasm in Western countries, whose occurrence is 336,000 new cases annually, and also being responsible for 132,000 deaths in the worldwide. The incidence of bladder tumors in Brazil were 7,550 cases in 1999, representing 2,8% of overall diagnosed cancer in both gender. One of the main therapeutic challenges is ide

10. Carcinoma of the renal pelvis and ureter
OBJECTIVE: To assess the occurrence of upper urinary tract urothelial tumors (UUTT) in Brazil. MATERIALS AND METHODS: We performed a clinical and histopathologic study of 33 patients who were diagnosed with a malignant neoplasm in the renal pelvis or ureter in the period of 1994 to 2004, in a single institution. RESULTS: Among the patients with upper urinary

11. Contiguous but dissimilar epithelial neoplasms of the urinary bladder
An unusual tumour of the urinary bladder is described. It consists of two distinct nodules each with a quite different histological appearance, one being mucus-secreting adenocarcinoma, the other transitional cell carcinoma. Where the nodules are in contact there is little intermingling of the two histological patterns and it is suggested that the findings a

12. Expression of bcl-2 in bladder neoplasms is a cell lineage associated and p53-independent event.
AIMS: To investigate bcl-2 and p53 protein expression in hyperplastic, metaplastic and neoplastic epithelia of the urinary bladder in relation to cell lineages (transitional versus glandular epithelia). METHODS: Formalin fixed, paraffin wax embedded archival tissue blocks of 29 transitional cell carcinomas (TCC), 11 adenocarcinomas, five specimens of cystiti
