Molecular Staging of Prostate Cancer: Dream or Reality?
February 01, 1999
Dr. de la Taille and colleagues from Columbia University provide an overview of the concept of molecular staging” of prostate cancer using reverse transcriptase–polymerase chain reaction (RT-PCR). They do an admirable job of summarizing all of the currently available data on the results of this assay in the clinical staging of prostate cancer. As they note, only their group and one other have been able to demonstrate that a positive assay correlates with final pathologic stage. A limited number of other studies have suggested that the RT-PCR assay can predict prostate-specific antigen (PSA) recurrence.
