  schema:description "Invasive disease-free survival is the yardstick of most trials that treat early breast cancer after surgery. A patient counts as an event if the cancer comes back anywhere as invasive disease, a new invasive cancer appears in either breast or elsewhere, or she dies of any cause; it deliberately ignores non-invasive recurrences. OlympiA used it to show that a year of olaparib helped BRCA carriers."@en ;
