Incidence of CNS involvement from metastatic BC (mBC) 10–16% in literature versus 36% in autopsy studies.
WBRT is the standard of therapy for mBC patients with multiple brain metastases.
Patients with oligometastatic disease should be considered for radical surgery or stereotactic radiosurgery (SRS).
The addition of lapatinib to trastuzumab increases OS in patients with CNS involvement by HER2-positive BC.
Systemic treatment options for TNBC and luminal-like BC are still very limited.
