What is the difference between radiosurgery and CyberKnife?

Both CyberKnife and Gamma Knife are dedicated stereotactic radiosurgery (SRS) treatment technologies, but Gamma Knife is limited to only treating cancer above the ear and in the cervical spine.

What is fractionated radiosurgery?

Fractionated radiosurgery: Fractionated radiosurgery delivers the radiation in multiple (or fractionated) doses over time, instead of in one large dose. Normal brain tissue and nerves in the head can tolerate many smaller doses of radiation better than one large dose.

What are the different types of radiosurgery?

There are 3 types of radiosurgery. Each type uses different equipment and radiation sources….Cobalt60 systems (Gamma Knife)

  • Head frame placement. In order to keep the head from moving during treatment, a box-shaped frame is attached to the head.
  • Tumor location imaging.
  • Radiation dose planning.
  • Radiation treatment.

What is the success rate of radiosurgery?

Results. Median overall survival and brain control were 14.1 months and 10 months, respectively. The 1-year and 2-year survival rates were 58% and 24%, and respective brain control were 43% and 22%.

Is CyberKnife better than radiation?

Cyberknife Is More Accurate Than Traditional Radiation Therapy. Because it’s able to target diseased tissue, Cyberknife SBRT is much more accurate than traditional radiation therapy. SBRT can deliver radiation to a margin of one to five millimeters surrounding a tumor.

What are the side effects of radiosurgery?


  • Fatigue. Tiredness and fatigue may occur for the first few weeks after stereotactic radiosurgery.
  • Swelling. Swelling in the brain at or near the treatment site can cause signs and symptoms such as headache, nausea and vomiting.
  • Scalp and hair problems.

Does Gamma Knife shrink tumors?

Gamma Knife radiosurgery is effective for small to medium-sized brain tumors. Radiation delivered by the Gamma Knife damages the DNA of abnormal cells so they can no longer reproduce. As a result, the tumor gradually shrinks.

Can radiofrequency be used to remove moles?

Summary. For many reasons, radiofrequency surgery is an excellent technique for the removal of moles and other lesions. It is now used in surgical techniques of various types in the fields of dentistry, veterinary medicine, and even brain surgery because of its laser-like precision-cutting capabilities.

How are metastases treated with single-fraction dosing stereotactic radiation therapy (SRS)?

All metastases were treated with linear accelerator–based SRS using the iPlan treatment planning system (Brainlab), and there was a 2-mm or 1-mm margin expansion on the gross tumor volume (GTV) to planning target volume (clinical target volume was considered equivalent to GTV). The single-fraction dosing SRS followed RTOG 90-05 guidelines.

What is the best way to remove a mole?

Standard biopsy techniques will be ideal, in the sense of clear margins and skin-depth visibility, but the patient may heal with a larger than ideal scar. There is always the option of plastic surgery; however, for many patients this is cost-prohibitive and seemingly excessive for a simple mole removal.

Is hypofractionated stereotactic radiosurgery (HF-SRS) effective?

Potentially, the use of a hypofractionated (nominally 2–5 sessions) stereotactic radiosurgery (HF-SRS) may provide an improved balance of tumor control and normal tissue toxicity over single-fraction SRS, particularly in larger tumors and those located next to or within critical structures.
