Avastin Shown to Slow Tumor Growth; Not Prolong Life
Two studies of the use of Avastin in ovarian cancer showed that the drug slowed tumor growth but did not improve overall survival.
“While we are looking for that silver bullet, this is a gift that shouldn’t be overlooked,” said Karen Orloff Kaplan, chief executive of the Ovarian Cancer National Alliance.
