摘要
To determine the correlation of the levels of circulating tumor cells (CTC) in breast cancer patients with clinical parameters like disease-free survival and response to therapy, we employed a previously reported quantitative real-time reverse-transcription polymerase chain reaction (QRT-PCR) assay for cytokeratin-19 (Ck19; Ann Oncol 2001; 12: 39-46). Our preliminary results based on this assay (Protocol A) prompted us to optimize the experimental conditions. Here we report an improved assay (Protocol 13), which more sensitively and specifically detects CTC in breast cancer patients.
