Article Abstract
Objective: To determine the effect of two weeks preoperative finasteride therapy in reducing prostate vascularity in terms of mean microvessel density (MVD) and expression of VEGF in prostate urothelium among patients of BPH by comparing with controls.
Study Design: Randomized controlled trial.
Place And Duration Of Study: Shifa International Hospital, Islamabad, from January 2013 to January 2014.
Methodology: A total of 80 patients of Benign Prostatic Hyperplasia (BPH) planned for Trans-Urethral Resection of Prostate (TURP) having prostate size of more than 40 grams on trans-abdominal ultrasonography was randomized into two groups, each group having 40 patients. The finasteride group (Group A) was prescribed oral 5 mg of finasteride daily for 2 weeks before surgery. The control group (Group B) did not receive any agent. After 2 weeks, TURP was performed and prostate samples were sent for histopathological determination of MVD and expression of VEGF.
Results: The mean age of patients was 66.21 ±10.08 years, ranging from 48 to 86 years. The mean prostate gland size was comparable in both groups (55 ±10.7 vs. 58.1 ±10.8 grams, p=0.21). Mean MVD in finasteride group (20.25 ±10.3) was significantly lower as compared to control group (48.9 ±22.6, p < 0.001). Similarly expression of VEGF was also significantly lower in finasteride group (30%) as compared to control group (65%) [p= 0.0017]. Mean MVD had a significant weak correlation with the size of prostate gland on Pearson correlation test (2-tailed) with r = 0.222.
Conclusion: Finasteride reduces microvessel density and hence prostate vascularity with only 2-week therapy and the mean MVD is clearly correlated with size of prostate.

Objective: To determine optimal CT perfusion (CTP) imaging parameters for evaluating the canine prostate and to assess the diagnostic utility of CTP combined with cytopathologic evaluation and B-Raf proto-oncogene (BRAF) gene mutation testing in dogs with prostate adenocarcinoma.
Methods: For this study, 10 male dogs were enrolled, comprising 4 healthy Beagles and 6 client-owned dogs with suspected prostatic neoplasia. Computed tomography perfusion was performed in the healthy dogs using varied contrast agent doses and injection durations.

Background: Prostate cancer remains a leading cause of cancer-related deaths in men, with radioresistance limiting treatment efficacy. This study investigates the role of Calbindin 1 (CALB1), a calcium-binding protein regulated by miR-186-5p, in prostate cancer progression and radiation response.
Methods: CALB1 expression was analyzed using GEO and TCGA datasets, and the regulatory relationship with miR-186-5p was validated.

Introduction And Importance: Accidental chemical injuries in medical settings are uncommon but can have devastating consequences. Formaldehyde (commonly in the form of formalin solution) is widely used as tissue fixative in clinics and laboratories. If inadvertently introduced into living tissue, formaldehyde causes rapid protein coagulation and tissue fixation, leading to cell death and necrosis.

Despite significant advancements in prostate cancer (PCa) diagnostics, it remains a challenge for accurate diagnosis and effective treatment. The aging global population and the established correlation between PCa incidence and advancing age suggest an anticipated rise in cases. Traditional clinicopathological parameters, such as prostate-specific antigen (PSA) levels, Gleason Grade Group, and pT stage, highlight the need for novel biomarkers to improve prognostic accuracy and risk assessment.

Objective: To evaluate standardized incidence ratios (SIRs) of cancer in patients with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV).
Methods: A systematic review and meta-analysis of studies from Medline, Embase, and Cochrane databases (inception to May 2025) was performed. Pooled SIRs were analyzed overall and by region, sex, age, AAV subtype, and cancer type.
