Brain tumor patients can now take part in a revolutionary therapy treatment option called GammaTile®. This surgically targeted radiation therapy (STaRT) uses small collagen tiles embedded with radiation seeds that are placed at the site of a brain tumor immediately after it’s removed.
The tiles provide immediate and constant radiation for up to two months after the tumor is removed, limiting the cancer cells’ ability to reoccur. AdventHealth Neurosurgeon Melvin Field, MD , and Radiation Oncologist Imran Mohiuddin, MD , performed the first GammaTile procedure in Central Florida in early 2021, providing a new treatment solution for local brain tumor patients.
New Hope for Brain Tumor Patients

For these patients and their families, this new treatment option brings hope. Currently, over 700,000 Americans live with brain tumors. Despite the efforts of brain tumor specialists throughout the world, the outcomes of patients with malignant brain tumors have improved very little over time.
GammaTile, which became available to patients with recurrent brain tumors in January 2019, is one of the most recent treatment options approved by the FDA for the treatment of brain tumors.
How Does GammaTile Work?

GammaTile is a biocompatible, permanent collagen tile implant that delivers radiation therapy to the area where the brain tumor was removed. The number of tiles used will depend on the size and location of the patient’s tumor. After the tiles are placed, GammaTile immediately begins delivering an even dose of radiation to the target area. Over time, the body naturally absorbs the collagen tile, and the titanium sources remain.
While a patient is in surgery to remove the brain tumor, Dr. Field and Dr. Mohiuddin decide how many tiles should be used and where they should be placed.
A Quick and Beneficial Procedure
From there, “It only takes about five minutes for me to place the tiles, then we close up the incision,” explains Dr. Field. Most patients don’t require a longer stay in the hospital because of the GammaTile therapy, and the need to possibly travel for radiation treatment after surgery is eliminated.

GammaTile benefits also include:
- Assurance that treatment is received
- Help to preserve the quality of life
- Limit to radiation exposure
- Minimized side effects, including hair loss
- Reduced time, travel and cost associated with added treatments
Most patients also experience fewer side effects from GammaTile therapy when compared to other radiation treatment options. However, following the surgery and tile placement, some patients have reported:
- Fatigue
- Headache
- Nausea
- Neurological deficit
- Seizures
- Skin irritation
- Vomiting
Candidates for GammaTile Therapy
As the first treatment specifically designed for use in the brain, GammaTile therapy is unlike other radiation treatments. It’s recommended that GammaTile not be used if you have a known history of hypersensitivity to bovine-derived materials, and is intended to be used in patients with newly diagnosed malignant brain tumors, as well as recurrent brain tumors.
