Excellence in Radiation Therapy in Orlando

When the need arises, Florida Hospital Cancer Institute offers residents of Central Florida and the surrounding regions excellence in radiation therapy in Orlando. When brain tumors cannot be fully or partially removed, radiation therapy may be the best option. While radiation therapy does not remove the tumor, it can cause its cells to die and eventually shrink. To learn more about radiation therapy in Orlando, or to schedule an appointment, call (407) 303-1700 or click here to fill out an online assistance form.

Types of Radiation Therapy

Radiation therapy utilizes high energy x-rays or other types of radiation to kill tumor cells or keep them from growing. There are two types of radiation therapy: external and internal. External radiation therapy uses a source that is outside the body to deliver radiation to the tumor's location. Internal radiation therapy, on the other hand, uses a radioactive substance that is sealed inside a needle, wire, catheter or "seeds" and placed directly into or near the brain tumor. The type of radiation therapy used depends largely on the type of tumor and its location in the brain.

Gamma Knife Radiosurgery

The Gamma Knife® isn't really a knife at all, but radiosurgery - a non-invasive neurosurgical procedure that uses powerful doses of radiation to target and treat diseased brain tissue while leaving surrounding tissue intact. This state-of-the art technology allows physicians to operate on brain lesions often considered inoperable. Gamma Knife surgery treatment offers new hope for patients with brain tumors, vascular malformations and functional disorders.

The Florida Hospital Gamma Knife Center was established in 1996, the first in Central Florida and has treated thousands of patients with a multitude of different brain lesions since that time.  The largest and most experienced in the region, Florida Hospital's Gamma Knife Center provides radiation treatment with the Leksell Gamma Knife© Perfexion, which is the most technologically advanced non-invasive brain surgery technique available today. Florida Hospital is the only facility in Central Florida using this robotic-assisted, state-of-the-art model to operate on brain lesions and tumors.The Leskell Gamma Knife® Perfexion emits finely focused beams of gamma radiation with minimal effect on surrounding normal tissue and without the usual risks of surgery or an incision. Gamma Knife surgery maximizes patient comfort and can be used to treat lesions that before were either inaccessible or were treated unsuccessfully by conventional surgery, chemotherapy and/or radiation therapy.The Leskell Gamma Knife® PerfexionTM offers unparalleled accuracy and precision, allows planning with all stereotactic and non-stereotactic image modalities (e.g., CT, MR, PET), and maximizes patient comfort. At Florida Hospital, our multidisciplinary team of neurosurgeons, radiation oncologists, neuro-otologists, neuro-oncologists and interventional neuroradiologists review cases weekly and a comprehensive plan of care is established for each patient's lesion.  Gamma Knife Radiosurgery is indicated when:

  • A patient has an unacceptable risk for anesthesia and open microsurgery
  • A traditional microsurgical approach might cause significant neurological damage
  • A patient has a recurrent or persistent tumor
  • A patient cannot safely receive any further conventional radiation treatment
  • A non-invasive treatment for a lesion is preferred

Additional benefits of Gamma Knife Radiosurgery include the following:

  • No anesthesia
  • Surgery without an incision
  • Lower costs than conventional brain surgery
  • Minimal discomfort
  • The ability to resume normal activities sooner
  • The absence of an incision eliminates the risk of hemorrhage and infection

The Gamma Knife procedure often takes less than 1 hour to plan and less than one hour to treat. Most patients are back home resuming their regular activities later that day.  No medicines have to be discontinued and no other concomitant therapies have to be delayed for Gamma Knife to be performed. Gamma Knife technology allows treatment of inoperable lesions. The procedure offers hope to patients who were formerly considered untreatable or at very high-risk for open-skull surgery.To learn more about the Gamma Knife treatment, visit our Gamma Knife Surgery website.

Spinal Cord Radiation Therapy

Radiation therapy is effective against tumors that have metastasized from other areas to the spine or spinal cord. These could include prostate tumors, breast adenocarcinomas, lung adenocarcinomas, renal cell carcinomas and gastric carcinomas.

To offset the side effects of radiation therapy such as nausea and vomiting, doctors at the Florida Hospital Brain and Spinal Cancer Program may recommend some medications designed to minimize their effects. 

Our tumor specialists are improving radiation therapies for spine and spinal cord tumors. Modifications to the dosage of radiation or the use of sophisticated technologies such as 3-D conformal radiation therapy are offering better protection to healthy tissue. Additionally, the Florida Hospital Brain and Spinal Cancer Program is at the forefront of trying new radiation therapies as they emerge from leading research institutions across the globe. Many of these advanced treatments are offered through the program’s clinical trials.
