Quantitative PSA RT-PCR for preoperative staging of prostate cancer.
BACKGROUND: The clinical value of detecting prostate specific antigen (PSA) mRNA in the peripheral blood mononuclear cell fraction of patients (pts) by standard RT-PCR assays with localized prostate cancer remains controversial. We used a quantitative RT-PCR assay to measure the PSA mRNA copy number in addition to the qualitative PSA RT-PCR and correlated the results with clinical parameters. METHODS: Total RNA was extracted from the peripheral blood mononuclear cell fraction of 115 prostate...Expand abstract
