Purpose: Small-cell neuroendocrine differentiation in prostatic carcinoma is an increasingly common resistance mechanism to potent androgen deprivation therapy (ADT), but can be difficult to identify morphologically. We investigated whether cyclin D1 and p16 expression can inform on Rb functional status and distinguish small-cell carcinoma from adenocarcinoma. Experimental Design: We used gene ...
The influence of prostatic fibroblasts on the growth of the prostatic carcinoma cell lines PC-3 and LNCaP was examined. In a double layer soft agar system, clonal growth of both cell lines was inhibited by all prostatic fibroblasts tested, irrespective of whether they were derived from malignant or non malignant prostate tissue. Irradiated fibroblasts and quiescent fibroblasts showed similar ef...
Preoperative intra-individual variation for determinations of prostate-specific antigen and prostatic acid phosphatase concentrations, 15-30% in 92 patients with benign prostatic hyperplasia, limits the diagnostic usefulness of both tumor markers. In benign prostatic hyperplasia (214 patients), concentrations of these tumor markers increased in the initial postoperative period. Prostatic acid p...
background and objective: non-specific granulomatous prostatitis is an uncommon diffuse inflammatory condition of the prostate. it is important because it may be mistaken for prostatic carcinoma. the aim of the study was to determine the prevalence of non-specific granulomatous prostatitis (nsgp) and comparing the results of transrectal ultrasonography, serum prostate specific antigen (psa) and...
BACKGROUND Prostatic carcinoma is the second most common cause of cancer-related deaths in males in the West. Approximately 20% of patients present with metastatic disease. We describe the case of a patient with metastatic prostate cancer to the bowel presenting clinically and radiologically as a primary caecal cancer. CASE PRESENTATION A 72 year-old man presented with abdominal discomfort an...
Optic nerve can be infiltrated with various tumors and inflammatory processes, with a considerable prevalence of primary over secondary tumors. Metastases of gastric carcinoma to the optic nerve are less frequently, and those of prostatic carcinoma very infrequently observed. A 66-year-old man presented with metastasis to the optic nerve with consequential vision loss to the level of light perc...
colorectal carcinoma is the most common gastrointestinal malignancy in the united states of america. in women the incidence is second to breast carcinoma; and in men it is the third most common carcinoma after lung and prostatic carcinoma. the overal incidence of colorectal carcinoma has had an increase in the first half of the past century, and has remained unchanged since. but the anatomic lo...
