Current chemotherapy already keeps some 70% of patients cancer-free for 3 years after surgery; beating that was a tall order, the Times notes. When Roche recently acquired Genentech, the American company trumpeted the possible new use of Avastin. Now it appears the Swiss firm may have overpaid. But the companies say they haven’t given up on early-stage use.
