Brain Metastasis

Phalke Neuro > Brain Metastasis

Brain metastasis occurs when cancer cells spread from another part of the body—like the lung, breast, or skin—into the brain. Unlike primary brain tumors, metastatic tumors originate elsewhere but migrate through the bloodstream or lymphatic system and implant in the brain. This condition affects approximately 150,000–200,000 individuals annually in the U.S.

What Causes Brain Metastases?

Any cancer can potentially spread to the brain, but the most common culprits include:

  • Lung cancer
  • Breast cancer
  • Melanoma
  • Others such as colon, kidney, and gynecologic cancers.

Recent data suggests that around 20–40% of non-small-cell lung cancer (NSCLC) patients develop brain metastases during the course of their disease.

 

Recognizing the Symptoms

Symptoms vary depending on tumor size, location, and swelling but often include:

  • Persistent or new headaches
  • Seizures
  • Weakness on one side of the body (hemiparesis)
  • Coordination issues (ataxia), especially with cerebellar involvement
  • Changes in memory, behavior, or emotions
  • Nausea, vomiting, or cognitive disturbances.

Diagnosis: Finding the Source and Scope

At Phalke Neuro, diagnosis is comprehensive and includes:

  • Neurological evaluation to assess reflexes, balance, cognition, and sensory functions.
  • Imaging tests:
    • MRI (contrast-enhanced) is the gold standard for detecting brain mets.
    • CT scans may be used when MRI isn’t feasible or in emergency settings.
    • PET scans help trace metastatic spread throughout the body.
  • Biopsy, when imaging is inconclusive, to definitively confirm metastatic origin.

 

Treatment: A Multi-Pronged Approach

Treatment strategies depend on tumor number, size, location, primary cancer type, and overall health.

1. Symptom Management

  • Corticosteroids (like dexamethasone) to reduce brain swelling and relieve pressure.
  • Anti-seizure medications if patients experience seizures.

2. Surgical Options

  • Surgery may be considered for patients with:
    • A single accessible lesion
    • Controlled systemic disease
    • Good functional status
  • Benefits include immediate symptom relief and improved survival when combined with other therapies.

3. Radiation Therapy

  • Whole-Brain Radiation Therapy (WBRT) treats multiple lesions but may increase cognitive side effects. Strategies like hippocampal-sparing or memantine use can reduce these risk.
  • Stereotactic Radiosurgery (SRS) (e.g., Gamma Knife, CyberKnife) delivers precise, high-dose radiation to specific lesions with minimal damage to surrounding tissues.

4. Systemic Therapies

  • Targeted therapies and immunotherapy are useful when primary cancers have actionable mutations (e.g., HER2 in breast cancer).
  • Chemotherapy has limited ability to cross the blood–brain barrier, but select agents may still be used in rare cases.
