RESUMO
OBJECTIVES: To present data on the prevalence of benign prostatic hyperplasia (BPH) in five Middle Eastern countries (Egypt, Turkey, Kuwait, Saudi Arabia, and the United Arab Emirates; the latter three forming a Gulf cluster). SUBJECTS AND METHODS: The SNAPSHOT programme was a multi-country, cross-sectional epidemiological survey conducted by telephone in a random sample of the adult general population. Subjects were considered to have BPH if they fulfilled the screening criteria, based on diagnosis, symptoms, and treatments received in the past 12 months. Current prevalence (last 12 months) was estimated. Association with co-morbidities was investigated via multivariate logistic regressions. Quality of life (QoL) was assessed using the three-level EuroQol five-dimensions questionnaire (EQ-5D-3 L). RESULTS: In total, 5034 of 33,486 subjects enrolled in the SNAPSHOT programme were men aged ≥50 years. In all, 998 of these men fulfilled the BPH screening criteria. The overall prevalence of BPH ranged from 13.84% (95% confidence interval[CI] 12.3-15.4%) in Turkey, to 23.76% (95% CI 21.8-25.6%) in Egypt, and 23.79% (95% CI 21.2-26.3%) in the Gulf cluster. Co-morbidities occurred more frequently in men with BPH compared to the non-BPH population (57% vs 31%; P < 0.001). Principal co-morbidities associated with BPH were cardiovascular, renal, and diabetes mellitus (P < 0.001). The men with BPH reported significantly reduced QoL, with lower EQ-5D-3 L utility values (0.8) compared to the male general population (0.9) aged ≥50 years (P < 0.001). CONCLUSION: The prevalence of BPH in these five Middle Eastern countries ranges from 13.84% to 23.79%. BPH has a negative impact on QoL and is associated with high levels of co-morbid diseases, indicating a need to better understand the management of the disease to reduce the impact on healthcare systems.
RESUMO
This is an update to the previously published Saudi guidelines for the evaluation and medical and surgical management of patients diagnosed with prostate cancer. Prostate cancer is categorized according to the stage of the disease using the tumor node metastasis staging system 7th edition. The guidelines are presented with supporting evidence levels based on a comprehensive literature review, several internationally recognized guidelines, and the collective expertise of the guidelines committee members (authors) who were selected by the Saudi Oncology Society and Saudi Urological Association. Local factors, such as availability, logistic feasibility, and familiarity of various treatment modalities, have been taken into consideration. These guidelines should serve as a roadmap for the urologists, oncologists, general physicians, support groups, and health-care policymakers in the management of patients diagnosed with adenocarcinoma of the prostate.

RESUMO
OBJECTIVE: To review the incidence, histopathological features and clinical outcomes of patients with incidental prostate cancer found in radical cystoprostatectomy (RCP) specimens excised for bladder cancer, to determine if these cancers affected the follow-up strategy and if prostate-sparing cystectomy would be appropriate for these patients. PATIENTS AND METHODS: We retrospectively reviewed the charts of men who had a RCP for transitional cell carcinoma (TCC) of the bladder, at our institution between 1987 and 2003. Patients with a preoperative diagnosis or clinical suspicion of prostate cancer were excluded from further analysis. We identified those men with incidental prostate cancer in the RCP specimens. The patients' demographic, histopathological and clinical outcome data were collected. RESULTS: In all, 217 men had RCP for TCC between 1987 and 2003; 13 were excluded from the study due to a preoperative diagnosis or clinical suspicion of prostate cancer, and 58 (28%) were found to have incidental prostate cancer. The mean (range) follow-up was 47 (6-157) months. Of these prostate cancers, 20% were of Gleason score > or = 7 and two patients developed local and metastatic prostate cancer recurrences. CONCLUSION: Incidental prostate cancer is a relatively common finding in RCP specimens, with a significant proportion having the characteristics of clinically relevant prostate cancer. The follow-up for prostate cancer should be incorporated with that for TCC and adapted according to the grade and stage of the prostate cancer. Preserving the prostate in an attempt to decrease the morbidity after RCP carries a high risk of significant prostate cancer in the residual prostatic tissue, suggesting that prostate-sparing cystectomy should only be reserved for a highly selected group of patients.

Tumor-derived immune suppression is considered to be a major mechanism of tumor evasion from the immune system destruction, however, little is known regarding the induction of T-cell functional suppression by tumor-derived exosomes. Herein, we investigate tumor-derived exosomes involved in normal immunological communications as means of inhibiting an antitumor T-cell response. Exosomes derived from LNCaP, a human prostate cancer cell line, were visualized by FACS and identified based on size (80-200 nm) in comparison to marker beads. Exosomes from tumor cell line inhibited T-cell proliferation. Dose-dependent apoptosis of T cells was induced by co-culture with tumor exosomes. Addition of anti-FasL antibody blocked the apoptosis induction by tumor exosomes. This study suggests that induction of T-cell apoptosis by tumor-derived exosomes appears to be a novel mechanism of tumor immune evasion.
