Promising Method For Early Diagnosis Of Cancer – Part 1 of 3
Promising Method For Early Diagnosis Of Cancer. A collaboration of US scientists and concealed companies are looking into a test that could find even one stray cancer chamber among the billions of cells that circulate in the human bloodstream. The hope is that one day such a test, given soon after a treatment is started, could indicate whether the therapy is working or not. It might even indicate beforehand which curing would be most effective. The test relies on circulating tumor cells (CTCs) – cancer cells that have detached from the main tumor and are traveling to other parts of the body.
In 2007, researchers at Massachusetts General Hospital, developed a “microfluidic chip,” called CellSearch, which could look on the number of stray cancer cells, but that test didn’t allow scientists to trap whole cells and analyze them. But on Monday, Mass General announced an concurrence with Veridex LLC, part of Johnson & Johnson, to study a newer version of the test.
According to the Associated Press, the updated assay requires only a couple of teaspoons of blood. The microchip is dotted with tens of thousands of tiny posts covered with antibodies designed to stick to tumor cells. As blood passes over the chip, tumor cells segregate from the pack and adhere to the posts.
