Cancer cell tests may help predict drug reaction

CHICAGO - COUNTING bits of prostate cancer found in a patient's bloodstream may help doctors better predict which drugs work, US researchers said on Saturday. They said men in a large clinical trial of Johnson & Johnson's newly approved drug Zytiga who had the lowest levels of circulating tumour cells - cells that break off from the main tumour and float around in the bloodstream - were more likely to survive than men who had more of these cells.
