Gain-of-function mutations in the catalytic subunit of phosphoinositide-3- kinase (PI3KCA) occur frequently in breast cancer. Kalinsky and colleagues show that PI3KCA mutations are associated with favorable clinicopathologic features and better clinical outcome, including survival. These findings will have to be considered in the design and interpretation of clinical trials with inhibitors of the PI3K pathway.
