OBJECTIVE To assess the additional value of prostate-specific antigen density in the diagnosis of prostate cancer in patients who undergo prostate biopsies. PATIENTS AND METHODS The study comprised 376 patients with symptoms of prostatism who were undergoing prostate biopsy. Digital rectal examination (DRE) and transrectal ultrasonography (TRUS) were performed and the prostate specific antige...

BACKGROUND Prostate-specific antigen (PSA) is currently used as a biomarker for diagnosis and management of prostate cancer (CaP). However, PSA typically lacks the sensitivity and specificity desired of a diagnostic marker. OBJECTIVE The goal of this study was to identify an additional biomarker or a panel of biomarkers that is more sensitive and specific than PSA in differentiating benign ve...

PSA is a 33-KDa serine protease that is produced predominantly by prostate epithelium. However, it has been shown that about 30-40% of female breast tumors produce PSA and its production is associated with the presence of estrogen and progesterone receptors. We have now developed a new tissue culture system to study PSA production in breast cancer and its association with prognostic factors...

This study compares the value of digital rectal examination (DRE) and prostate specific antigen (PSA) determination in the detection of prostate cancer. 1,000 men aged > or = 50 from the Osijek surroundings were examined. The subjects with prostatitis were excluded from the study. The subjects with elevated concentration of total prostate specific antigen and/or digital rectal examination suspe...

BACKGROUND/AIMS The combined role of whole-body magnetic resonance imaging (WB-MRI), bone scintigraphy and prostate specific antigen (PSA) were considered in predicting metastases and prognosis of prostate cancer (PCa). METHODS Totally 38 PCa patients underwent WB-MRI, bone scintigraphy and PSA detections, and 34 benign prostate hyperplasia (BPH) patients were checked with PSA. Pearson correl...

Miyamoto and colleagues present data that prostate-specific antigen/prostate-specific membrane antigen (PSA/PSMA)-based measurements of androgen receptor (AR) signaling in circulating tumor cells (CTC) enable real-time quantitative monitoring of intratumoral AR signaling. This finding indicates that measuring AR signaling within CTCs may help to guide therapy in metastatic prostate cancer and h...

discoidin domain receptor (ddr) is a new member of the receptor tyrosine kinase family. there are two isoforms of discoidin domain receptor (ddr), ddr1 and ddr2. these receptors play a major role in the adhesion, motility and cell proliferation. due to the important role of ddr2 in the development of tumor extension, this receptor is pivotal in the field of carcinogenesis. the aim of this study...
