In collaboration with several Toronto hospitals, we examine circulating tumor cells in the blood from lung, colon and prostate cancer patients, and characterize them based on the expression of cancer-specific markers. 

Using nanotechnology, cancer cells are captured from whole blood in a microfluidic device, and separated into distinct subpopulations based on the expression level of epithelial adhesion proteins.

Captured prostate cancer cells are examined for levels of androgen receptor and androgen receptor variant 7 (ARV7), and the expression levels are then correlated to PSA, LDH, ALP levels and to the degree of metastases. 

CTC studies are expected to provide the most benefit for patients that do not have metastatic disease, as an early diagnostic tool or to monitor disease recurrence. With the rapid development of new CTC technologies, it may be possible to monitor heterogeneous CTCs at earlier stages of cancer and gain new insight into the utility of CTC analysis.
