摘要: PURPOSEDetection of occult carcinoma in patients with breast cancer may aid the establishment prognosis and development new therapeutic approaches. To improve on existing methods detection, we have developed a reverse-transcriptase polymerase chain reaction (RT-PCR) assay for keratin 19 (K19) transcripts to identify mammary cells peripheral blood bone marrow cancer.PATIENTS AND METHODSPeripheral-blood or samples obtained from 34 stages I IV 39 control subjects without were screened K19 mRNA by nested primer PCR.RESULTSIn reconstitution experiments, RT-PCR reliably detected 10 1 million normal peripheral-blood mononuclear (PBMN) cells. Four stage had detectable transcript blood. Five six histologically negative biopsies following preablative chemotherapy before autologous ...
