To study the mechanism of regression of human prostatic cancer following androgen ablation, the androgen-responsive PC-82 human prostatic adenocarcinoma xenograft was used as a model system. Castration of male nude mice bearing PC-82 xenografts results in a 50% tumor regression by 2 wk following androgen ablation. This regression is due to a sequence of biochemical and morphological events that...
In this study 1192 cases were studied from 1986 to1996 in Imam Khomeini and Ekbatan hospitals of Hamadan province. 75 cases were found having pathologic stage A cancer (occult cancer). So the prevalence of stage A prostatic cancer is 4.78% . From statistic point it is 10%-25% .  ...
The search for the precursor of invasive prostatic adenocarcinoma has intensified in recent years, focusing on the spectrum of histopathologic changes referred to as high-grade prostatic intraepithelial neoplasia. This microscopic finding, considered to be the most likely precursor of invasive carcinoma (7), is characterized by cellular proliferations within pre-existing ducts and glands, with ...
Abnormal metabolism is a widely accepted biological signature of prostatic diseases, including prostate cancer and benign prostate hyperplasia. Recently accumulated epidemiological and experimental evidence illustrate that the metabolic syndrome, impaired mitochondrial function, and prostatic pathological conditions intersect. The perturbed metabolism and metabolic mediates influence key signal...
Background: Transrectal ultrasonography guided needle biopsy of prostate frequently used for early detection of cancer has faced the pathologists with a major diagnostic challenge. In recent years P504S has been used as a tumor cell marker for definitive diagnosis of prostatic cancer in small biopsy specimens.Methods: 70 prostate needle biopsies and 6 transurethral resections (TURP) containing ...
The clinical significance of serum basic fetoprotein (BFP) in prostatic cancer was investigated together with serum prostatic acid phosphatase (PAP), gamma-seminoprotein (gamma-Sm) and prostate specific antigen (PA). Investigated in this study were 40 patients with prostatic cancer, ranging in age from 50 to 85 years (mean age: 69.5 years). According to clinical staging, 3 cases (7.5%) had a st...
Prostate cancer and prostatic calcifications have a high incidence in elderly men. We aimed to investigate the diagnostic capabilities of susceptibility-weighted imaging in detecting prostate cancer and prostatic calcifications. A total number of 156 men, including 34 with prostate cancer and 122 with benign prostate were enrolled in this study. Computed tomography, conventional magnetic resona...
INTRODUCTION The possibilities of PSA (prostate specific antigen) test in screening of prostatic cancer may be evaluated by measuring its sensitivity, specificity and positive predictive value. The majority of reference articles in this field has evaluated the possibility of detection of prostatic cancer by radioimmunoassay (RIA). MATERIAL AND METHODS Prospective study included 2000 male pati...
