Prostate Cancer Microparticles In Men Undergoing Radical Prostatectomy, Malcolm James Dewar
Prostate Cancer Microparticles In Men Undergoing Radical Prostatectomy, Malcolm James Dewar
Electronic Thesis and Dissertation Repository
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 …

Journal of Health Disparities Research and Practice
The Prostate is an exocrine gland of the male reproductive system. Prostate cancer is a malignancy that begins in the prostate gland and has the potential to spread to other parts of the body. The cancerous tumors are most commonly diagnosed through a biopsy of the prostate or medical imaging. Prostate cancer can be treated with surgery, brachytherapy or external beam therapy. External beam therapy is a method of delivering a beam or multiple beams of high energy x-rays to a tumor. Proper treatment planning of external beam therapy allows for the beams to be placed precisely in order to …

Prostate Cancer Microparticles As A Next Generation Screening Tool For Prostate Cancer, Khurram M. Siddiqui
Electronic Thesis and Dissertation Repository
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 …
