The results of this research appear in the article, "Frequent Expression of PD-L1 on Circulating Breast Cancer Cells," published online in Molecular Oncology, and demonstrate that PD-L1 positive CTCs were found in 11 out of 16 (68.8%) patients with circulating tumor cells. This particular application of the CELLSEARCH® System is for research purposes only and has not been cleared by the US Food and Drug Administration. This publication potentially adds a new important application to the research use of the CELLSEARCH® System to characterize CTCs for PD-L1.
