Potential side effects of CyberKnife® treatment for lung cancerFatigue.Breathing difficulties.Cough.Hemoptysis (coughing up blood)Radiation pneumonitis.Radiation fibrosis.Complications (such as pneumothorax) resulting from fiducial marker insertion.Exposure to airways and/or nearby tissue.
What does CyberKnife do to a tumor?
Instead of delivering radiation to all brain tissues, CyberKnife radiosurgery targets the tumor(s) with sub-millimeter precision, protecting healthy brain tissues and reducing the risk of common cognitive side effects of whole-brain radiation.
How long does a CyberKnife treatment last?
Treatments are performed on an outpatient basis, with each treatment lasting between 30 to 90 minutes. The number of treatments vary depending on the tumor size, location and shape, but typically only one to five daily sessions are required.
How quickly does CyberKnife work?
How long does it take for treatment to take effect? CyberKnife treatment results may take weeks or months to detect. The outcome depends on the condition being treated. Anova will monitor a patient's progress through periodic follow-up examinations and imaging tests such as MRIs and CT scans.
How long does it take for a tumor to shrink after radiation?
At the same time, if a cell doesn't divide, it also cannot grow and spread. For tumors that divide slowly, the mass may shrink over a long, extended period after radiation stops. The median time for a prostate cancer to shrink is about 18 months (some quicker, some slower).
What is the success rate of CyberKnife?
As a primary treatment Cyberknife can achieve a local control of nearly 90% in patients with a median follow up of 18 months. Radicular pain has been relieved in 25–85% of patients and neurological deficits improved to a lesser degree.
Is CyberKnife better than surgery?
In many clinical situations, CyberKnife has local control and effectiveness that is equivalent to surgery. However, due to its non-invasive nature, the risk of side effects is significantly lower with CyberKnife. 2. Real-time tumor tracking results in less radiation to the nearby normal tissues.
Who is a good candidate for CyberKnife?
It's a good option for early-stage or low-grade prostate cancer. CyberKnife may be a better choice if you can't have anesthesia or if your anatomy makes brachytherapy difficult. If you have treatment with CyberKnife, you may need other therapies as well.
How long does fatigue last after CyberKnife?
You may find you feel mildly fatigued for a couple of days. However, most patients are back to work and normal activity levels within a day or two.
Will radiation shrink a tumor?
Radiation therapy kills cancer cells or slows their growth by damaging their DNA. Radiation therapy (also called radiotherapy) is a cancer treatment that uses high doses of radiation to kill cancer cells and shrink tumors.
What is the maximum size of tumor for CyberKnife?
The maximum tumor diameter ranged from 1.8- 18 cm. Patients were explained the advantages and disadvantages of cyberknife SBRT and made final treatment decision for themselves.
What can I expect after CyberKnife radiation?
After treatment and follow-up There are minimal side effects from CyberKnife treatment. The most common side effect is fatigue. Most of the time, patients are able to go back to their usual activities but will need someone to drive them home immediately after treatment.
How does Cyberknife work?
How CyberKnife Works. CyberKnife uses a high-energy X-ray machine on a robotic arm to precisely deliver radiation beams that destroy tumor cells and stop tumor growth while avoiding damage to healthy tissue. The treatment process is the same for each CyberKnife patient.
What is the most advanced technology in the Swedish radiosurgery?
The Swedish Radiosurgery Center has the most current CyberKnife technology that employs the Synchrony Tracking System to match radiation beam delivery to the motion of the tumor. This tracking system eliminates the need for breath-holding techniques, or head or body frames to stabilize patient movements. The system automatically corrects for any patient or tumor movement. This highly sophisticated technology is particularly beneficial in the treatment of lung, liver, pancreas, kidney and other abdominal or thoracic tumors that move when the patient breathes.
How does a robotic arm work?
The robotic arm is very flexible and can move and deliver beams of radiation from many different directions and angles. The computer uses the treatment plan to precisely focus every beam on the specific target area.
What is CyberKnife?
CyberKnife isn’t a knife at all — in fact, this treatment doesn’t require any surgery or incisions. But its name affirms it can be just as precise. The CyberKnife system is an advanced radiation therapy treatment that delivers accurate doses of radiation to hard-to-reach tumors and is even able to track their movement.
How does Cyberknife work?
Sometimes, doctors refer to tumors as “inoperable” — either because they are hard to reach or because surgery may not be the best treatment for that person. If you’ve been told you have inoperable cancer, or if surgery just isn’t the right fit for you, CyberKnife may be an option.

What is a cyberknife?
The CyberKnife System consists of three key components: A lightweight linear accelerator produces beams of high-energy radiation that can destroy cancer cells. The robotic arm moves the linear accelerator to a wide variety of positions, allowing treatment from nearly any angle. Two ceiling-mounted cameras take frequent pictures ...
What tumors are treated with Cyberknife?
Extracranial tumors that have been treated by the CyberKnife System include tumors of the spine, lung, prostate, liver, and pancreas. Although this list is by no means exhaustive, CyberKnife is being used to treat:
Can you breathe with synchrony?
With the Synchrony Respiratory Tracking System, patients can breathe normally throughout their treatment without breath-holding or gating techniques, enabling clinicians to continuously track, detect and correct for tumor and patient movement throughout the treatment.
Can Cyberknife treat spinal tumors?
With the CyberKnife System’s revolutionary Xsight Spine Tracking System, it is now possible to treat tumors in or near spinal structures without implanting radiographic markers or fiducials.
What is a cyberknife?
What is CyberKnife? CyberKnife is a brand name for a device that delivers stereotactic body radiation therapy (SBRT). It’s a form of external beam radiation. It can be used to treat prostate cancer and other types of cancer. Although it contains the word “knife” and is sometimes referred to as “radiosurgery,” there’s no knife or incision.
What is Cyberknife ultrasound?
This will be similar to when you had your biopsy. CyberKnife will use the markers to track the tumor during treatment. Then you’ll need some imaging tests to assess the location, size, and shape of the tumor.
How long does radiation therapy last?
This is a noninvasive, painless procedure. Each session will last anywhere from 30 to 90 minutes. Once it’s over, you should be able to get up and resume your normal activities right away.
What to do after radiation treatment?
A few months after treatment, you’ll probably need to schedule new imaging tests, such as CT, MRI, or PET. The images will help your doctor evaluate your response to radiation treatment. If no cancer can be found, you may not need further treatment. You’ll need careful monitoring for some time, though.
How many treatments do you need for a syphilis?
You’ll likely need one to five treatments on consecutive days. This can all be accomplished on an outpatient basis. There’s no need for anesthesia or other medications, so you can eat and take medications as usual. Avoid lotions and powders on the area to be treated, and wear comfortable clothing.
Is Cyberknife good for prostate cancer?
It’s a good option for early-stage or low-grade prostate cancer. CyberKnife may be a better choice if you can’ t have anesthesia or if your anatomy makes brachytherapy difficult. If you have treatment with CyberKnife, you may need other therapies as well.
What to do if you have cancer after SBRT?
If there’s still evidence of cancer after SBRT, your doctor will make some recommendations on the next steps.
