OBJECTIVE To morphometrically compare local atherosclerotic changes in cancerous prostate with those in noncancerous prostate specimens, as epidemiological studies report a positive association between the prevalence of general atherosclerosis and prostate cancer. MATERIALS AND METHODS The intima-to-media-ratio (IMR) of 538 prostate capsular tissue arteries was measured in 50 prostate cancer-...

The treatment time needed for high-intensity focused ultrasound (HIFU) ablation might be decreased substantially by using the split-focus approach, so we made a prototype 4.2-MHz split-focus therapeutic transducer combined with a small 6.5-MHz imaging ultrasonic probe for transrectally treatment of canine prostatic cancer and used it to experimentally evaluate the feasibility of using split-foc...

PURPOSE We determined the differential diagnosis of concomitant pathological conditions in men with overactive bladder symptoms. MATERIALS AND METHODS We performed an observational, descriptive study to elucidate the differential diagnosis in men with overactive bladder symptoms using a previously validated overactive bladder symptom questionnaire. All patients provided an extensive history, ...

Although Wnt signaling has been shown to be important for embryonic morphogenesis and cancer pathogenesis of several tissues, its role in prostatic development and tumorigenesis is not well understood. Here we show that Wnt signaling regulated prostatic epithelial branching morphogenesis and luminal epithelial cell differentiation in developing rat prostate organ cultures. Specifically, Wnt sig...

Prostate cancer is the most common malignancy in men and is the second leading cause of cancer-related mortality in developed countries. Recent work has revealed the significance of CIPinteracting zinc finger protein 1 (CIZ1) in cancer cell biology, but its roles in prostatic carcinoma are unknown. Our study compared CIZ1 gene expression in banked prostatic carcinomas versus matched paraneoplas...

Prostatic hyperplasia (PH) is a common urologic disease that affects mostly elderly men. PH can be classified as benign prostatic hyperplasia (BPH), or prostate cancer (PCa) based on its severity. Oxidative stress (OS) is known to influence the activities of inflammatory mediators and other cellular processes involved in the initiation, promotion and progression of human neoplasms including pro...

This case report refers to a 47-year old patient with prostate cancer associated with schistosomiasis mansoni, who was submitted to radical prostatectomy. This is the third report published in the literature with respect to this association, and up to the present time it is still not known whether a cause and effect relationship exists between the two pathologies. The association between schist...

BACKGROUND c-KIT expression has been related to bone metastasis in human prostate cancer, but whether c-KIT expression can be similarly classified in canine prostatic tissue is unknown. This study assessed c-KIT and Ki67 expression in canine prostate cancer (PC). c-KIT gene and protein expression and Ki67 expression were evaluated in forty-four canine prostatic tissues by immunohistochemistry, ...
