Pfizer today announced results from an exploratory analysis of the Intergroup Exemestane Study (IES) at a median follow-up of 91 months in estrogen-receptor positive (ER+) or estrogen-receptor unknown (ER-unknown) women that looked at breast cancer free survival (BCFS) and censored deaths that occurred prior to breast cancer relapse.
