Brain metastases occur when cancer cells spread to the brain from a primary tumor elsewhere in the body, most often from the lung, breast, melanoma, kidney, or colon. At the Duke Cancer Institute, a multidisciplinary team of neuro-oncologists, neurosurgeons, radiation oncologists, medical oncologists, neuroradiologists, pathologists, palliative care specialists, and supportive care professionals collaborates to create individualized care plans. This overview explains how brain metastases are evaluated, common treatment approaches, how symptoms are managed, and what to expect during follow-up and survivorship care.
How Brain Metastases Are Evaluated at Duke Cancer Institute
Evaluation typically begins with a detailed medical history, a focused neurological examination, and imaging. Magnetic resonance imaging (MRI) of the brain is the standard test to detect, locate, and characterize metastases. In many cases, additional imaging of the primary cancer or a full-body scan may be performed to assess overall disease status. Sometimes a biopsy is needed to confirm the tumor type, especially when the primary source is unknown or when results will change treatment planning. The care team reviews all findings to determine the number, size, and location of metastases, as well as how the cancer overall is behaving. This comprehensive assessment supports a clear, evidence-based treatment plan tailored to the individual.
Key Parts of the Evaluation Process
- Neurological examination to check thinking, coordination, strength, and sensation
- Brain MRI with and without contrast to visualize metastases
- Whole-body imaging (CT, PET, or both) to gauge systemic disease
- Biopsy or review of prior tissue when the cancer type is uncertain
- Multidisciplinary tumor board review to align treatment strategy
Common Treatment Approaches for Brain Metastases
Treatment is personalized based on the number and location of metastases, the type and biology of the cancer, overall health, and patient preferences. Options may be used alone or in combination with the goal of controlling brain disease, preserving neurologic function, and maintaining quality of life. Local therapies target the brain lesions directly, while systemic treatments address cancer throughout the body. The team at Duke Cancer Institute coordinates these approaches to balance effectiveness with side effects.
Local Therapies for Brain Metastases
- Stereotactic radiosurgery (SRS), such as Gamma Knife or CyberKnife, which delivers precise high-dose radiation to tumors in one or a few sessions
- Whole-brain radiation therapy (WBRT) for multiple metastases, though it may affect thinking and memory in some people
- Surgical resection for accessible, symptomatic, or solitary lesions where removal can relieve pressure and provide tissue for diagnosis
Systemic and Medical Treatments
- Targeted therapy for cancers with specific molecular alterations, such as EGFR mutations in non–small cell lung cancer or BRAF mutations in melanoma
- Immunotherapy, including checkpoint inhibitors, for eligible patients with cancers that respond to immune-based approaches
- Chemotherapy or hormone therapy when these agents penetrate the brain sufficiently and match the cancer’s biology
Managing Symptoms and Side Effects
Brain metastases and their treatment can cause headaches, seizures, weakness, speech or balance problems, and changes in thinking or mood. The Duke Cancer Institute team works closely with supportive care and rehabilitation specialists to manage these issues. Medications such as corticosteroids can reduce brain swelling, while anticonvulsants may be used for seizures. Physical, occupational, and speech therapy can help maintain function and improve daily living. Social work and palliative care services offer practical support, symptom relief, and help with goals of care discussions.
Supportive Strategies Often Used
- Corticosteroids to decrease edema and improve neurological symptoms
- Antiepileptic drugs when seizures occur or are suspected
- Rehabilitation therapies (physical, occupational, speech) to aid mobility and communication
- Counseling and psychosocial support for patients and caregivers
- Advance care planning and coordination with primary oncology
Follow-Up, Survivorship, and Long-Term Monitoring
After initial treatment, regular follow-up with imaging and clinic visits helps assess response, detect new lesions, and monitor neurocognitive and functional outcomes. The oncology and neurology teams coordinate long-term surveillance, adjusting therapy as needed and addressing late effects of treatment. Survivorship care plans may include strategies to manage memory and fatigue, optimize rehabilitation, and support emotional health. At Duke Cancer Institute, follow-up is structured to provide continuity, with clear communication among cancer care, neurology, rehabilitation, and primary care teams.
What to Know About Clinical Trials and Emerging Options
Participation in clinical trials can provide access to newer systemic agents, targeted combinations, and innovative radiation approaches at Duke Cancer Institute. Trials may test new drugs, combinations, or supportive care interventions that could benefit patients with brain metastases. The care team reviews trial eligibility based on cancer type, prior treatments, performance status, and imaging findings. Discussing trial options early ensures that patients and families understand potential benefits, risks, and the study procedures involved.

Questions to Ask the Care Team
Understanding the proposed plan can help you feel more prepared and confident. Consider asking:
- What is the number, size, and location of the metastases, and what does this mean for prognosis?
- Which local and systemic treatments do you recommend, and why?
- What are the potential benefits and risks, including effects on thinking, mood, and daily function?
- How will symptoms such as swelling or seizures be managed?
- Are there clinical trials or emerging options that might be appropriate?
- What follow-up schedule and rehabilitation supports are available?
Conclusion
At the Duke Cancer Institute, care for brain metastases is guided by a multidisciplinary team that combines precise diagnostics, tailored local and systemic therapies, and robust supportive care. The approach emphasizes clear communication, evidence-based treatment, and attention to quality of life. By coordinating advanced therapies with rehabilitation and survivorship support, the team helps patients and families navigate brain metastases with informed, compassionate care.
