GammaTile® Therapy

Haynes Neurosurgical Group now offers GammaTile® Therapy, which is the latest FDA-cleared device for the treatment of operable brain tumors. Brain tumors can significantly impact various aspects of your brain's functioning and early treatment of brain tumors is crucial for better patient outcomes.

Our team is excited to introduce this innovative and advanced treatment as part of our commitment to providing advanced, compassionate care to our patients.

Understanding GammaTile® Therapy

GammaTile® Therapy is a Surgically Targeted Radiation Therapy (STaRT) designed to deliver precise radiation treatment directly to the tumor bed during surgery. GammaTile is a biocompatible, permanent collagen tile that is a source of Cesium-131 (Cs-131). It gradually releases radiation to target residual tumor cells while minimizing damage to surrounding healthy tissue.

Each tile is 2 cm x 2 cm and is 4 mm thick. Each tile contains 4 Cesium-131 (Cs-131) titanium-encased sources. 

How It Works

During tumor removal surgery, our skilled neurosurgeons strategically place GammaTiles® at the tumor site. The number of tiles used will depend on the size and location of the tumor, covering the tumor cavity with tiles.

These tiles immediately begin delivering a uniform radiation dose immediately, targeting any remaining cancer cells effectively.

Over time, the radiation dose is delivered, and the tiles are naturally absorbed by the body, leaving behind only inactive titanium sources.

  • GammaTile® Therapy is designed to deliver 50% of the therapeutic dose within the first 10 days after surgery. This is said to help prevent residual tumor cells from replicating.2
  • GammaTile® Therapy also claims to deliver 88% of the therapeutic dose within 30 days, with more than 95% of the dose delivered by 6 weeks.2

Benefits of GammaTile® Therapy

GammaTile® Therapy offers multiple benefits:

  • Targeted Treatment: GammaTile® Therapy targets residual tumor cells precisely, maximizing effectiveness while minimizing damage to healthy brain tissue.
  • Convenience: Administered during surgery, GammaTile® Therapy eliminates the need for repeat radiation treatments, additional hospital visits, or outpatient treatments.
  • Reduced Side Effects: By delivering targeted radiation therapy, GammaTile® Therapy helps minimize side effects commonly associated with traditional radiation treatments.

Clinical Outcomes of GammaTile® Therapy

Studies have shown that GammaTile® Therapy can significantly reduce treatment site recurrence in patients with recurrent meningiomas and brain metastases. Additionally, it demonstrates a potential for improved overall survival in patients with recurrent glioblastomas.5–6

Side Effects of GammaTile® Therapy

A large number of patients experience fewer side effects than with other radiation treatments.1–2, 6 Postoperative side effects, such as nausea, vomiting, headache, sleepiness, neurodeficit, seizures, and skin irritation, may be experienced by some patients. However, these side effects should settle on their own as the body adjusts.

Symptoms related to radiation exposure vary depending on the radiosensitivity of the exposed tissue, the amount of radiation delivered, and the placement of GammaTile®. If you experience any unexpected effects, please contact our team immediately.
