Risk of seizures in a population of women with BRCA-positive metastatic breast cancer from an electronic health record database in the United States.

Background: Incidence and risk factors for seizures among women with advanced breast cancer (BC) and brain metastases are not well characterized across treatment-related or clinical subtypes. This study leveraged a large real-world dataset to describe incidence and risk factors for seizures in BRCA-associated metastatic breast cancer.

Methods: The Optum® de-identified electronic health records database was used.
