Rationale for prostate cancer screening continues to be debated as an update to a large European trial reconfirms a reduction in death rates from prostate cancer in men who are screened for the disease. The study, however, found no significant difference in overall mortality between the two arms of the trial. More »
This is a very emotional issue. Any time a group claims less screening is good, I always take it with a grain of salt—yet the data certainly seem to support that generalized screening with PSA may not impact survival in the general population. More »

The reactive stromal phenotype is an important factor for prostate cancer progression and may be a new target for treatment and prevention. A new high efficiency preclinical protocol, the EPI bioassay, reflects the interaction of endocrine, paracrine and immune, (EPI) factors on induced androgen metabolism in human prostate reactive stroma. The bioassay is based on co-culturing human primary prostate stromal cells and LAPC-4 prostatic adenocarcinoma cells in a downscaled format of 96-well-plates for testing multiple doses of multiple target compounds. Metabolism of dehydroepiandrosterone (DHEA) with or without TGF1-induced stimulation (D+T) of the reactive stroma phenotype was assessed by increased testosterone in the media and PSA production of the epithelial prostate cancer cells. Using the non-metabolizable androgen R1881, effects from direct androgen action were distinguished from stromal androgen production from DHEA. Stromal cell androgenic bioactivity was confirmed using
To investigate the outcomes and potential effect of improved longitudinal screening in men presenting with high-risk (advanced clinical stage [>T2b], Gleason score 8-10 or prostate-specific antigen [PSA] level >20 ng/mL) prostate cancer (PC).|The Institutional Review Board approved, Institutional Radical Prostatectomy Database (1992-2010) was queried for men with high-risk PC based on D'Amico criteria. Year of surgery was divided into two cohorts: the Early PSA Era (EPE, 1992-2000) and the Contemporary PSA Era (CPE, 2001-2010). PC features and outcomes were evaluated using appropriate comparative tests.|In total, 667 men had high-risk PC in the EPE and 764 in the CPE. In the EPE, 598 (89.7%) men presented with one high-risk feature; 173 (29.0%) men had a Gleason score of 8-10 on biopsy. In the CPE, 717 (93.9%) men presented with one high-risk feature (P = 0.004) and 494 (68.9%) men had a Gleason score of 8-10. At 10 years, biochemical-free survival (BFS) was 44.1% and 36.4% in the EPE
