Objectives: To determine changes in prostate microparticle (PMP) concentrations in men with prostate cancer (PCa) after digital rectal examination (DRE), after radical prostatectomy (RP), and at follow-up.
Materials and Methods: 22 men were recruited before RP. Four blood specimens were collected – baseline (specimen 1), post-DRE (specimen 2), immediately post-RP (specimen 3), and follow-up (specimen 4). Pre- and post-DRE urine was collected (Specimen A and B respectively). Flow cytometric analysis of biofluids was performed with fluorescent-labeled antibodies against prostate-specific membrane antigen (PSMA) and polysialic acid. Total MP (TMP) and dual positive (PMP) events per µl of plasma or urine were …

Currently available screening tests for prostate cancer (PCa) are neither very sensitive nor specific. Microparticles (MP) are submicron tumor cell fragments released by PCa cells into the circulation and offer a possible means of sampling the tumor. We evaluated the utility of a MP blood test using nanoscale flow cytometry to distinguish patients with PCa from patients with benign prostatic hyperplasia (BPH). We used monoclonal antibodies against prostate specific membrane antigen, gastrin releasing peptide receptor and ghrelin peptide ligand.
We found higher but statistically insignificant, PSMA and Ghrelin dual +ve MP counts in the BPH group. Our results show that …
