Prostate Specific Antigen Testing and Prostate Specific Antigen Velocity for the Screening of Prostate Cancer (Master's thesis, University of Calgary, Calgary, Canada). Retrieved from https://prism.ucalgary.ca. doi:10.11575/PRISM/27466http://hdl.handle.net/11023/2598Prostate specific antigen (PSA) testing for the screening of prostate cancer is controversial with medical and governmental organizations issuing contradictory statements regarding its use. My research looked at the utilization of the PSA test for the screening of prostate cancer in Calgary, Alberta for 2011 and if sociodemographic factors influenced the rate of testing. I studied whether PSA velocity is better than a single PSA test in predicting prostate biopsy outcome and if sub-dividing Gleason score 7 prostate cancers improves the predictive ability of PSA tests. My research found that PSA testing does not follow official guidelines in younger men and that certain sociodemographic factors do influence the rate of PSA testing. I found that PSA velocity is not better than the PSA test in predicting prostate biopsy diagnosis and that sub-dividing Gleason score 7 prostate cancers can increase the clinical utility of the PSA test.engUniversity of Calgary graduate students retain copyright ownership and moral rights for their thesis.
