A comparative performance analysis of total PSA, percentage free PSA, PSA velocity, and PSA density versus the detection of primary circulating prostate cells in predicting initial prostate biopsy findings in chilean men
(CIENCIAS, 2014)
Introduction. PSA parameters have been used in an attempt to improve the diagnostic yield of prostate screening tests; the detection of primary malignant circulating prostate cells (CPCs) may improve the diagnostic yield ...
Extended use of P504S positive primary circulating prostate cell detection to determine the need for initial prostate biopsy in a prostate cancer screening program in Chile
(CIENCIAS, 2014)
BACKGROUND: To determine the frequency of primary circulating prostate cells (CPC) detection according to age and serum PSA levels in a cohort of men undergoing screening for prostate cancer and to determine the diagnostic ...
