The treatment plan, along with all imaging and scans, is completed days before any actual treatment begins. After the scans, the radiation oncologist and medical physicists will develop a customized plan. Since patients do not require a head frame, CyberKnife can be administered in one to five sessions. Clinical data shows that for certain cancerous and non-cancerous conditions, fractioned-dose radiation administered over two to five sessions provides better results.
Both CyberKnife and Gamma Knife treatments are similar, as they both use external radiation to kill cancer cells and shrink tumors while avoiding healthy tissue. Gamma Knife unfortunately is limited to only positions in trying to reach the tumor and patients must wear a mounted head frame before and during the treatment. Meanwhile, CyberKnife has pinpoint precision down to the sub-millimeter and can treat the tumor from virtually any angle, pain-free and non-invasively.
Thanks to an exclusive real-time, tumor-tracking guidance system CyberKnife also is more equipped to handle tumors that might move slightly due to natural body and organ movement. While both CyberKnife and Gamma Knife precisely treat cancerous, noncancerous, and recurrent tumors, CyberKnife has distinct advantages. Because of the more advanced technology, CyberKnife can treat tumors in organs throughout the body that move with normal breathing by utilizing real-time X-ray images of the targeted location.
Gamma Knife is only able to treat cancers in the brain and cervical spine, where movement can be stabilized. Some special features of CyberKnife treatment include robotic mounting and multiple imaging of the tumor in real time, which means that there is rarely need for implanting guidance markers. Gamma Knife procedures utilize static images that were taken previously in order to find the treatment location, and therefore are not updated in real-time. The specially designed robotic equipment used by CyberKnife helps improve patient positioning and the frameless nature of the treatment also significantly increases clinical efficiency and client comfort.

Shubha, thank you for reaching out. Cahlon, who says that proton therapy would not be the right treatment for this particular situation.
Thanks for your comment. How is proton therapy similar or different from gamma knife radiotherapy? Have you used proton therapy to treat a chondrosarcoma at the brain stem? Wendy, thank you for reaching out. Gamma Knife is a form of highly focused radiosurgery—-it uses x-rays rather than proton beams. Gamma Knife is also limited by the size of the tumor, i.
Proton therapy definitely can be used to treat chondrosarcoma. The best published outcomes for this tumor are with protons. We encourage you to contact Nancy Lee for a consultation at: I am surprised by one of your answers. Proton Therapy is used in prostate cancer but not in metastatic prostate cancer. I understand the part that they are at different locations.
My friend in Poland have prostate cancer. Prostate was removed manually by surgeon. Latter hormonal therapy. With time, cancer went to sacral bone, removed by gamma radiation. Time passes, highly active otherwise healthy 76yo man. His PSA is starting to raise, cancer is back.
When is the right time the new cancer location will be found. Hopefully another gamma radiation will be possible. But I was hoping that in case that gamma radiation is acceptable then proton therapy should also be acceptable but less damaging to surrounding tissue. Please comment. Jan, thank you for your comment.
Cahlon, who says that in general proton therapy is not used for metastatic disease unless there is prior radiation to the same area. Cheryl, thank you for reaching out. We recommend you contact Massachusetts General Hospital:. I have been getting lupron injection every 3 montjhs. PSA my radiology oncologist is considering local radiation treatment.
PSA now is 0. Am I a candidate for proton treatment? Michael, thank you for reaching out. Yes, proton therapy is a potential option for treatment. If you are interested in making an appointment, you can contact the office at Oren Cahlon at:.
Indican cirugia radical y quimioterapia tradicional porque donde vivo no hay otra cosa. Gracias Graciela. I had state 3 lung cancer in and was cured with lobectomy, chemotherapy before and after surgery and radiation. In I developed a a right supraclavicular metastatic node, and was again saved by surgery, followed by chemo and radiation. I am healthy, active and feel great. Mariela, thank you for reaching out. It is difficult to tell ahead of time whether proton therapy would be appropriate for a cancer that returns — you might be a candidate, but it would depend on a number of factors specific to the case.
Norman, thank you for reaching out. Yes, proton therapy can be used to treat prostate cancer. If you are interested in a consultation, you can contact the office at Oren Cahlon at:.
I've had a left mastectomy which spread to the lymph nodes. I've had chemo and now I need to have radiation. Would proton therapy work for me? Ann, thank you for reaching out. Yes, proton therapy can be used for this condition. If you are interested in a consultation, contact the office of Oren Cahlon at John, thank you for reaching out. Proton therapy very recently started to be used for anal cancer at some centers, although Memorial Sloan Kettering is not currently using protons for this cancer.
We suggest you contact University of Pennsylvania and Massachusetts General Hospital, who may have begun using proton therapy for anal cancer. Cahlon, who informs us that MSK does not use proton therapy to treat this particular condition.
We suggest you consult with your personal physician about treatment options. My mother has non hodgkins Lymphoma and we are looking at further treatments after it seems chemotherapy has failed with a view to a cure. Having read up on Proton therapy, it seems that this targeted treatment is a viable option. Can you confirm if that is so and if MSK would provide such treatment?
