1. 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

2. O papel dos genes do pepsinogênio C (PGC) e do antígeno de membrana específico da próstata (PSMA) no diagnóstico do câncer da próstata / The role of Prostate Specific Membrane Antigen (PSMA) and Pepsinogen C (PGC) gene tissue expression as an adjunctive method to prostate cancer diagnosis
INTRODUÇÃO: O diagnóstico do câncer de próstata em pacientes com níveis séricos do antígeno prostático específico persistentemente elevados após biópsia prostática negativa representa um grande desafio para urologistas e patologistas. A baixa especificidade do antígeno prostático específico e a baixa sensibilidade da biópsia prostática guia

3. Impact of diet and glutathione s-transferase system genotype in the susceptibility to cancer / Impacto do perfil alimentar e genotipico do sistema glutationa S-transferase na susceptibilidade ao cancer
Background: Glutathione-S-Transferase gene family has an important role in the biotransformation and detoxification of different xenobiotics and endogenous compounds. The high admixture of the Brazilian population may represent a unique model in which the types and frequency of genetic polymorphisms of GST enzymes are less influenced by ethnicity. Objective:

5. Efficiency of 6- and 12-punctures biopsies to detect prostate cancer in patients with PSA< 10 ng/mL and normal digital rectal examination
OBJECTIVE: Establish the efficiency of 6- and 12-punctures transrectal ultrasound-guided needle biopsies in low risk patients for prostate cancer. Six-punctures (sextant) biopsies were compared to 12-punctures biopsies, assessing which is the best strategy to detect this neoplasm. MATERIALS AND METHODS: Among 240 patients submitted to prostate biopsy, 54 wit

6. Estudo da proteína de choque térmico GRP78 para o desenvolvimento de um sistema de receptor-ligante para o câncer de próstata / Use of the heat-shock protein GRP78 for the development of a receptor-ligand system in prostate cancer
Introduction: Despite the advances in diagnosis and treatment, advanced prostate cancer remains a lethal condition. Improved methods of therapy are needed to reduce the morbidity and mortality rates associated with this disease. The Glucose-regulated protein-78 (GRP78), a stress-responsive heat-shock protein involved in antigen presentation, was recently des

7. PAGE-1, an X chromosome-linked GAGE-like gene that is expressed in normal and neoplastic prostate, testis, and uterus
We have used a combination of computerized database mining and experimental expression analyses to identify a gene that is preferentially expressed in normal male and female reproductive tissues, prostate, testis, fallopian tube, uterus, and placenta, as well as in prostate cancer, testicular cancer, and uterine cancer. This gene is located on the human X ch

8. Detection of apoptosis by the TUNEL technique in clinically localised prostatic cancer before and after combined endocrine therapy.
AIMS: Apoptosis in prostate cancer was evaluated after three months of combined endocrine therapy to investigate the association with tumour grade, tumour stage, and the immunohistochemical detection of p53 and bcl-2 in tumour cells before and after therapy. METHODS: Twenty six formalin fixed, paraffin wax embedded core biopsies and corresponding prostatecto
