Cyberknife Radiation For Brain Tumors

Potential Side Effects Of Cyberknife Treatment For Brain Cancer

CyberKnife® Robotic Radiosurgery for Inoperable Brain Tumors

Treatment with the CyberKnife System is well-tolerated with a low risk of toxicity. Side effects associated with CyberKnife treatment are usually mild and temporary. As with any radiation treatment, side effects can also be severe in some patients and lead to permanent injury or even death. Discuss your specific case with your physician/s to fully understand the potential risks associated with your treatment. Possible side effects could include but not limited to:

  • Increased intracranial pressure expressed by: Nausea

Brain Metastasis Treatment With Cyberknife

In order to evaluate efficiency of treatment of brain metastases with the CyberKnife system, it is possible to take individual free of charge on-line patient consultation where data from medical history are assessed. In order to apply for an on-line consultation, please send data from on-line contact form or data uploading form here. Data necessary to initially assess treatment options: Magnetic resonance imaging with a description or access code to the scan in a data base or images of the scan in DICOM format, recorded in CD, or uploaded in data uploading system at the hospital’s website .

Onsite consultations in the Centre. Possible therapy tactics, side effects and course of the therapy are explained in a consultation. Image data from previous analyses and diagnostic radiology are demonstrated and explained.

Tumour board. The Medical Treatment Law stipulates that treatment tactics of each patient is examined in a multidisciplinary tumour board consisting of a neurosurgeon, radiation oncologist and radiologist. The treating doctor presents patient’s medical data to the members of tumour board. If necessary, the patient is invited to attend the tumour board in person to directly discuss different aspects of treatment with the tumour board members.

Choosing Cyberknife For Treatment

Our doctors work with you to evaluate whether CyberKnife radiosurgery is the right treatment for you. If you have a cancerous or noncancerous condition that is considered inoperable or not treatable using conventional radiation therapy, then CyberKnife treatment may be an option for you. Your doctor may also recommend CyberKnife if you are looking for an alternative to traditional surgery, or as an additional treatment choice if you have already received the maximum radiation therapy dose using conventional options.

Compared with other radiation therapies, which last six to nine weeks, the CyberKnife treatment period is much shorter. It typically lasts 5 days or less, with 20- to 30-minute sessions daily.

What Are The Benefits Of The Cyberknife

There are many benefits to a CyberKnife procedure. It is non-invasive, does not require a headframe or painful Immobilization device and it is able to reach areas of the body previously thought untreatable. It is ideally suited for those who are unable to undergo surgery or who do not wish to risk surgery.

Cyberknife Is Proven Effective For Brain Cancer

Brain Stereotactic Radiosurgery with CyberKnife

The CyberKnife Robotic Radiosurgery System is specifically designed to target cancerous tumors throughout the body. But its high-level of precision gives it supremacy when treating the tumors inside the delicate brain area. The CyberKnifes ability to focus high levels of radiation on only the cancerous cells, allows the vital healthy cells around the brain tumor left unharmed and able to continue functioning normally.

At Orange County CyberKnife and Radiation Oncology Center in Southern California, our cancer experts are skilled at utilizing the CyberKnife System to target tumors in the brain and to develop a plan that allows the optimum results for each individual patient.

Alternating Electric Field Therapy

This type of treatment uses a noninvasive portable device that interferes with the parts of a cell that are needed for tumor cells to grow and spread. It is given by placing electrodes that produce an electric field on the outside of a persons head. The available device is called Optune.

Alternating electrical field therapy may be an option for people newly diagnosed with glioblastoma or for those with recurrent glioblastoma. Researchers have found that people with recurrent glioblastoma who used the device lived as long as those who received chemotherapy. In addition, they had fewer side effects. Other research shows that people newly diagnosed with glioblastoma lived longer and were less likely to have the disease worsen when this treatment was used along with temozolomide after radiation therapy. This treatment approach is now considered a recommended option for glioblastoma.

How Can I Handle Fatigue

The fatigue you feel from cancer and radiation therapy is different from other times you may have felt tired. Itâs an exhaustion that doesnât get better with rest and can keep you from doing the things you normally do, like going to work or spending time with family and friends. It also can seem different from day to day, which makes it hard to plan around it. It can even change how well youre able to follow your cancer treatment plan.

Let your doctor know if youâre struggling with fatigue. They might be able to help. There are also things you can do to feel better:

  • Take care of your health. Be sure youre taking your medications the way youre supposed to. Get plenty of rest, be as active as you can, and eat the right foods.
  • Work with a counselor or take a class at your cancer treatment center to learn ways to conserve energy, reduce stress, and keep yourself from focusing on the fatigue.
  • Save your energy for the activities that are most important to you. Tackle them first when youâre feeling up to it.
  • Keep a balance between rest and activities. Too much bed rest can make you more tired. But dont over-schedule your days without giving yourself breaks.
  • Ask for help from family and friends. If fatigue is interfering with your job, talk with your boss or HR department and ask about taking some time off from work or making adjustments in your schedule.

Protecting Healthy Tissue Protecting Quality Of Life

Treatment with the CyberKnife System is well-tolerated with a low risk of toxicity. Despite the high dose rate associated with SRS, the CyberKnife System has been proven to deliver radiation with sub-millimeter precision, which means minimal radiation is delivered to the healthy brain tissues that surround the lesion or tumor1. This can significantly reduce the risk of the most common side effects of traditional radiation therapy, including fatigue and cognitive impairments to memory and concentration and can protect the sensitive tissues involved in important functions such as motor control, touching, hearing and vision. Most patients can quickly return to their daily routines with little interruption to their normal activities.

Whats The Outlook After Undergoing The Gamma Knife Procedure

CyberKnife Treatment for Brain Tumor

The success of the Gamma Knife procedure depends on the size, location, type of lesion, your personal medical history, and other factors. Discuss your expectations and outlook with your neurosurgeon and your radiation oncologist before treatment.

The goal of Gamma Knife surgery is for the radiation to stabilize, shrink or destroy the tumor or lesion. Depending on your condition, you may or may not need additional Gamma Knife treatment or traditional now-more-manageable surgery. You will have follow-up CT and/or MRI scans to check on treatment progress.

It may take weeks, months, a year to see the full effects of treatment. For example, pain relief if you have trigeminal neuralgia can occur anytime between one day and six months, with most people improving within one month. Cancerous tumors typically become stable or get smaller over a period of weeks to months. Many noncancerous tumors stop growing immediately , but may not get smaller in size. Arteriovenous malformations may take two to three years to resolve after treatment.

How Does Cyberknife Treat Brain Tumors

The CyberKnife SRS system improves on other radiosurgery techniques by eliminating the need for a fixed metal head frame attached with screws to the patients head. A mesh mask is worn during treatment instead. The highly maneuverable, precise delivery system enables doctors to achieve an exceptional level of accuracy in a non-invasive manner. CyberKnife is an outpatient treatment performed in one to five treatment visits with minimal to no side effects. During the CyberKnife treatment, hundreds of highly concentrated and incredibly precise beams of radiation are targeted directly to tumors and lesions in the brain. Patients dress comfortably in their own clothes and, depending on the treatment center, they can bring music to listen to during the treatment.

Key Cyberknife Treatment Benefits

  • No head frame is required
  • Good cancer control
  • Reduced incidence of common cognitive side effects
  • Treatments may be completed in as little as 1-5 sessions within 1-2 weeks
  • Most patients can continue normal activity throughout treatment
  • Typically does not require interruption of chemotherapy cycles or immunotherapy treatments
  • Patients previously treated with whole brain radiotherapy may be candidates for CyberKnife SRS treatment
  • Patients previously treated with SRS may be candidates for CyberKnife SRS in other areas of the brain

Brain Cancer And Cyberknife Treatment

by CyberKnife Miami | Oct 14, 2020 | Brain Cancer

How do you know if you have a brain tumor or youre just paranoid?

Here are the most common symptoms:


Tingling or Stiffness on one side of the body

Loss of balance

Change in vision

If youre experiencing any of these symptoms for a period of time, say a week or longer, and theyre not going away, its time to see a doctor for a complete physical exam.

Dont be shy to tell your doctor youre afraid it might be a brain tumor. Chances are its not but you should express your concerns and even ask for a brain scan just to make sure its not all in your head. .

Should the test results determine you do have a brain tumor, dont panic. Its not an automatic death sentence anymore. Even if its brain cancer. Chances are you can get it treated quite easily and effectively if you know your treatment options.

While brain surgery is one option, its always best if you can avoid it. Its horrifically invasive and can cause a brain bleed and lead to all kinds of temporary and/or life long problems, including loss of motor skills such as the ability to walk or talk, the loss of vision and hearing, loss of senses, memory, ability to balance and/or result in a brain infection after surgery that can be deadly or require an even longer recovery period.

Confusion and memory problems can be permanent after brain surgery.

We cannot stress this strongly enough.

Cyberknife As An Alternative To Surgery

Surgery is often a chosen treatment method for brain cancer to remove as much of the tumor as possible and thereby eliminating the symptoms. However, there are some tumors which cannot be reached without significant risk of damaging parts of the brain. And, there are tumors that have grown so large they are more intertwined with parts of the brain. There are also patients who may not be healthy enough to undergo the trauma of surgery. And, there are those who simply refuse to take the risks of surgery.

For these cases, the CyberKnife System can help. CyberKnifes robotic arm can reach inoperable tumors and beam high-doses of radiation directly to the spot at numerous angles to kill the cancerous cells. There is no risk of surgery or anesthesia use and there are very few side effects. CyberKnife treatment is comfortable and allows patients to be treated on an outpatient basis.

Stereotactic Radiosurgery Treated Tumor In Just Three Sessions

Phoenix Cyberknife talks radiation treatment options for brain tumors

Vicki Ebertz had never had any serious health problems and enjoyed an active lifestyle until the beginning of 2016, when she began losing her balance and falling down for no apparent reason.

My leg would just give out from under me, and down Id go, says Vicki, 68. It started to happen more often, and eventually I had to use a cane. I also had problems hearing. It was pretty traumatic, and nobody knew what was going on.

When X-rays, hearing exams and other tests came back normal, Vickis Scripps primary care physician, , ordered a brain MRI. Vicki learned she had a brain tumor on the vestibulocochlear nerve, in an area deep beneath her right ear, which directly affected her balance and hearing.

I was terrified, Vicki says. When you hear you have a brain tumor, you immediately panic. You think youre going to die.

An alternative to brain surgery

Her doctors couldnt determine if the tumor was cancerous or not without a biopsy, but either way, Vicki needed treatment. Surgery was the most common option. Then Scripps radiation oncologist Patrick Linson, MD, recommended an alternative: CyberKnife stereotactic radiosurgery at Scripps Clinic Radiation Therapy Center Vista CyberKnife.

Despite its name, radiosurgery is not a surgical procedure, says Dr. Linson. Rather, it is a non-invasive form of radiation therapy treatment that accurately targets small and large tumors in the brain and body without exposing nearby tissue. So it is ideal for brain tumors.

Definition Of Types Of Recurrences

The radiation field was defined as the tumour volume contained within the prescription dose. Tumour recurrence was defined as a progression of tumour volume within the initial radiation field, i.e. within the prescription dose. Out-of-field recurrence was defined as tumour progression immediately adjacent to the radiation field and hence outside the initial prescription isodose. The occurrence of a new meningioma was defined as a distant tumour unrelated to the radiation field.

How Does Cyberknife Work

CyberKnife is an advanced stereotactic radiosurgery system that is the most precise technology available for treating cancerous tumors. It offers brain cancer treatment without invasive surgery, which can have complications especially with brain surgery. Because it can beam high doses of radiation at various angles directly to your tumor, and track the slightest movement, it leaves healthy cells unharmed. This not only preserves the important functions of the brain, it also almost eliminates side effects seen with traditional radiation treatments. Recovery time is minimal and patients can go about their normal duties usually the next day. CyberKnife is clinically proven effective for treating brain cancer and is used alone or sometimes in conjunction with other brain cancer treatments.

What Are The Complications Or Side Effects Of Cyberknife Radiosurgery

Complications may occur but the frequency and severity are typically mild. The complications tend to relate to the region that is receiving treatment. There are symptoms that may occur regardless o fthe region receiving treatment. After treatment sometimes patients experience headaches or feel nauseated or tired. These symptoms are typically temporary. Uncommon complications may include skin reddening or vomiting. Delayed symptoms may include swelling, inflammation, or scarring in the treatment site or adjacent normal tissue regions. Specific side effects vary with the site that is being treated. We urge you to speak with your physician prior to proceeding with treatment.

How You Have Radiotherapy

Brain Stereotactic Radiosurgery with CyberKnife

You are usually admitted to hospital urgently for radiotherapy for spinal cord compression. You stay in hospital while you have the treatment.

You have the radiotherapy as a single treatment or a series of daily treatment sessions called fractions. Normally you have one a day. But occasionally you may have 2 fractions a day, for example, just before a weekend.

Whether you have a plastic mould made to keep you still while you have treatment depends on the part of the spine that has cancer. Youre likely to have a plastic mould made if the cancer is in the upper part of your spine.
