Cyberknife vs other stereotatic radiosurgery

Could you please help me understand the difference between cyberknife and other stereotatic radiosurgery. It seems that some hospitals have cyberknife and others have what they call stereotatic radiosurgery or something similar. I would assume that cyberknife is the newest, most high tech and does the least amount of damage to surrounding tissue in the lungs, but I am confused after talking to my oncologist and my thoracic surgeon. They indicate that they all do damage to surrounding tissue.

There are a number of machines that can perform radiosurgery/stereotactic body radiation therapy (SRS/SBRT). Most modern accelerators are capable of it if the proper packages are installed. They vary somewhat in accuracy, but for most conditions accuracy is not the issue. The CyberKnife can track motion and we have shown internally that you get less normal lung tissue treated to potentially damaging doses with CyberKnife than with the other system we have that can do this stuff. But it takes 1.5 hours to treat each day. With the other system you can treat in just a few minutes. I think the difference in lung tissue is pretty important with larger tumors, but probably less so with smaller tumors. Used properly, either can be highly effective and safe.

Thank you very much Dr. Medbery. Do you have an opinion on whether cyberknife or novalis would be a better choice to use on three nodules in right lung that measure 10mm, 8mm and 7mm-two are in upper lobe and one in lower lobe? Also, approximately how many treatments of cyberknife would be required to do all three? Thank you.

In general, with smaller lesions there would be more lung sparing with CK. They are usually treated in three days each

does cyberknife treatment allow a biopsy of the tumor that is in the lung? Or does it just destroy the tumor in the lung?

Biopsy is a separate procedure. CyberKnife does not result in any incisions or other invasive procedure. Sometimes gold seeds must be placed, and some centers will do a biopsy at the same time

CyberKnife is totally different from radiosurgery which involves advanced accelerators. With CyberKnife better motions are tracked and is highly effective and safe....
