METHODS FOR THE DETECTION AND QUANTIFICATION OF CIRCULATING TUMOR CELL MIMICS

摘要

The disclosure provides methods for detecting circulating endothelial cells (CECs) that mimic CTCs with respect to aspects of their immunofluorescent staining and with respect to aspects of their morphological characteristics (CTC mimics). The present disclosure is based, in part, on the unexpected discovery that CTC mimics can be detected in non-enriched blood samples among CTC candidate cells. The present disclosure is further based, in part, on the discovery that CTC mimics can be detected in non-enriched blood samples by combining the detection of one or more immunofluorescent markers in the nucleated cells of a non-enriched blood sample with an assessment of the morphology of the nucleated cells.

1. A method of distinguishing circulating tumor cells (CTCs) from CTC mimics, comprising: (a) determining the presence or absence of one or more immunofluorescent CTC markers in nucleated cells in a non-enriched blood sample to detect a CTC candidate, (b) determining the presence or absence of one or more immunofluorescent CEC markers in the CTC candidate, and (c) assessing the morphology of the CTC candidate, wherein CTCs are distinguished from CTC mimics based on a combination of distinct immunofluorescent staining and morphological characteristics.
