OBJECTIVES The risks of identifying prostate cancer (PCa) in patients with serum total PSA (tPSA) between 4 and 10 ng/dl are between 25 and 35%. There are no data in Brazil showing the incidence of disease when all variables for PSA assessment are considered altogether, specifically tPSA, free fraction, PSA velocity and PSA stratified by age. The objective in this work was to define the inciden...

BACKGROUND In the AFFIRM trial, enzalutamide significantly increased overall survival (OS) for men with metastatic castration-resistant prostate cancer (mCRPC) after chemotherapy versus placebo and significantly decreased prostate-specific antigen (PSA) levels. The goal of this post hoc analysis was to associate levels of PSA decline from baseline after enzalutamide with clinical outcomes in th...

OBJECTIVE To evaluate the performance of total PSA (tPSA), the free/total PSA ratio (f/tPSA), complexed PSA (cPSA) and the complexed/total PSA ratio (c/tPSA) in prostate cancer detection. METHODS Frozen sera of 442 patients have been analysed for tPSA, free PSA (fPSA) and cPSA. 131 patients had prostate cancer and 311 patients benign prostatic hyperplasia. RESULTS Differences in the distrib...

Prostate Specific Antigen (PSA), a member of kallikrein family, is a specific serine protease of prostatic tissue. In some case reports, changes in PSA levels after acute myocardial infarction (AMI) have been reported. In this study we evaluated variations in PSA levels post-AMI. Twenty-six male patients who had PSA levels within reference limits were included in the study. The diagnosis of AMI...

BACKGROUND Patients with prostate cancer (PCa) show a lower ratio of free prostate-specific antigen (fPSA) to total PSA (tPSA) in serum than patients with benign prostatic hyperplasia (BPH). The patterns of the intracellular PSA isoforms in malignant and benign prostatic tissue have been studied as potential molecular reasons for this phenomenon. METHODS Prostatic tissue samples were obtained...

OBJECTIVE To compare the prevalence of comorbidities, health care utilization, and costs between moderate-to-severe psoriasis (PsO) patients with comorbid psoriatic arthritis (PsA) and matched controls. METHODS Adults ages 18-64 years with concomitant diagnoses of PsO and PsA (PsO+PsA) were identified in the OptumHealth Reporting and Insights claims database between January 2007 and March 201...

BACKGROUND AND PURPOSE In a retrospective analysis, we examined factors influencing the outcome of prostate cancer (PCa) patients receiving salvage radiotherapy (SRT) for PSA recurrence after radical prostatectomy (RP). MATERIAL AND METHODS 306 patients received 3D-conformal SRT at a median pre-SRT PSA of 0.298 ng/ml. Post-SRT progression was defined as PSA ⩾0.2 ng/ml above nadir and rising f...

OBJECTIVE To assess whether Free/Total prostate specific antigen (PSA) would enhance prostate cancer detection in men with total serum PSA between 2.5 and 10 ng/ml. METHODS This case control study was conducted in the Department of Urology and Renal Transplantation, Jinnah Hospital, Lahore from January 2001 to June 2004. A total of 200 consecutive patients with symptoms of prostate disease, a...

The aim of the paper is to determine whether IGF1, IGFBP3 and IGF1/IGFBP3 molar ratio in addition to PSA and one-nucleotide polymorphism in PSA and CYP17 gene might contribute to early diagnostics of prostate cancer (PCa). Serum level of PSA, IGF1 and IGFBP3 in the group of 158 individuals (92 PCa and 66 controls) was examined by RIA method and IGF1/IGFBP3 was calculated. PCR RLFP method was us...
