Summary
This study collects spinal fluid, blood, saliva, and tumor samples from 139 adults with HER2-positive or triple-negative breast cancer that has spread to other organs but not yet to the brain. Researchers will analyze these samples for tumor DNA that might predict when the cancer will reach the brain. Participants are followed every 6 months for 3 years to track outcomes.
