The detection and characterization of circulating tumor cells (CTC) holds great promise for personalizing medicine and optimizing systemic therapy. However, low specificity, low sensitivity, and the time consuming nature of current approaches have impeded clinical adoption. Here we report a new method using surface-enhanced Raman spectroscopy (SERS) to directly measure targeted CTCs in the presence of white blood cells. SERS nanoparticles with epidermal growth factor peptide as a targeting ligand have successfully identified CTCs in the peripheral blood of 19 patients with squamous cell carcinoma of the head and neck (SCCHN), with a range of 1 to 720 CTCs per milliliter of whole blood. Our technique may provide an important new clinical tool for management of patients with SCCHN and other cancers. Cancer Res; 71(5); 1526–32. ©2011 AACR. |
