Circulating prostate tumor cells detected by Reverse transcription-PCR in men with localized or castration-refractory prostate cancer : Concordance with CellSearch assay and association with bone metastases and with survival
Reverse transcription-PCR (RT-PCR) assays have been used for analysis of circulating tumor cells (CTCs), but their clinical value has yet to be established. We assessed men with localized prostate cancer or castration-refractory prostate cancer (CRPC) for CTCs via real-time RT-PCR assays for KLK3 [kallikrein-related peptidase 3; i.e., prostate-specific antigen (PSA)] and KLK2 mRNAs. We also assess
