Tumors shed cells into the blood of patients with cancer, but researchers have long sought a reliable way to detect these rare cells.
Now, however, investigators at Massachusetts General Hospital in Boston report successful tests with a unique microchip-based device that can efficiently and selectively separate circulating tumor cells from peripheral blood samples (Nagrath S et al. Nature. 2007;450:1235-1239).
