Strong sales of new cancer drugs and a severe U.S. flu season helped lift Swiss drug maker Roche Holding AG's revenue by 6 percent in the first quarter. The world's biggest manufacturer of cancer drugs said Thursday April 11, 2013 that sales rose to 11.56 billion Swiss francs (US $12.4 billion, 9.47 billion euro) during the first three months of the year, up from 11.03 billion francs in the same period last year.
