What is it indicated for?

The CellSearchTM Circulating Tumor Cell Kit is intended for the enumeration of circulating tumor cells (CTC) of epithelial origin (CD45-, EpCAM+ and cytokeratin 8 & 18+, and/or cytokeratin 19+) in whole blood in conjunction with the CellTracks® AutoPrep System, the CellSpotter® Analyzer or CellTracks® Analyzer II, and the CellSearchTM Circulating Tumor Cell Control Kit.

The CellSearchTM Circulating Tumor Cell Kit is intended for the enumeration of circulating tumor cells (CTC) of epithelial origin (CD45-, EpCAM+ and cytokeratin 8 & 18+, and/or cytokeratin 19+) in whole blood in conjunction with the CellTracks® AutoPrep System, the CellSpotter® Analyzer or CellTracks® Analyzer II, and the CellSearchTM Circulating Tumor Cell Control Kit.

The presence of CTC in the peripheral blood, as detected bythe CellSearchTM Circulating Tumor Cell Kit, is associated with decreased progression free survival and decreased overall survival in patients treated for metastatic breast cancer. A CTC count of 5 or more per 7.5 mL of blood generally is predictive of shorter progression free survival and shorter overall survival.

Indications for use as stated in the FDA summary.
