A painless and non-invasive radiation treatment that can treat tumors located in any part of the body without requiring even a single incision is known as Cyberknife. This treatment makes use computer-controlled robotics and image guidance technology for delivering accurate radiation doses to the tumor while sparing surrounding healthy tissue. Multiple tumors located at different positions are treated at the same time as the high-radiation beams are delivered from almost any angles. Cyberknife is a new hope for those patients who have untreatable or inoperable lesions. Another major benefit of this treatment is that it is completed in 1-5 treatments as compared to traditional radiation therapy that may require up to 8 weeks of daily treatments.
Types of Cancers Treated by CyberKnife
Head and Neck
Patients suffering from head and neck malignancies and are not appropriate candidates for surgery or have tumors in specific areas that cannot be treated with traditional radiation as they are close to some significant structures. These all conditions can only be treated with the help of Cyberknife that delivers radiation with great surgical accuracy so as to save the essential structures (such as brain stem, eyes, optic nerves) that may be at risk.
The Cyberknife delivers high-doses of radiation that are specifically directed onto the kidney tumors. There are some patients who cannot undergo kidney cancer surgery due to some medical condition are successfully treated with the help of Cyberknife radiation system. All the treatments are performed on an outpatient basis that takes 1-5 days without any overnight hospital stay. There could be minimum or no side effects and it also provides for faster recovery.
Brain Non Tumors
Trigeminal Neuralgia : The non-invasive and painless Cyberknife treatment is considered as an ideal option for treating trigeminal neuralgias. Trigeminal neuralgias is very painful condition that involves the trigeminal nerve. If this condition recurs then the treatments can also be repeated.
Arteriovenous Malformation : The lesions such as AVMs that are usually located in accessible areas can be successfully treated with the help of Cyberknife. Even a single treatment session can cure these AVMs.
Acoustic Neuroma : Acoustic Neuromas can be successfully treated with the help of stereotactic radiosurgery. The success rate of the treatment is as high as 90% in the case of acoustic neuroma. The size of majority of these tumors will get stable and gradually they will also shrink.
Brain Metastases : Cyberknife system is considered as an alternative to conventional surgery for those patients who are suffering from either single or multiple metastases.
Skull Base Tumors : Cyberknife is a best alternative to conventional surgery for treating skull-base tumors. Some of these tumors are located close to some vascular and nerve structures that makes it difficult for a surgery to treat them. In such cases, Cyberknife treatment is planned in such a way that spares these structures.
Meningioma : Meningiomas are locates close to significant structures that can be successfully treated with the help of help of Cyberknife system that does not involve any invasive frames.
Pituitary Adenoma : The irradiation of healthy tissue can be minimized as Cyberknife conform the shape of the tumor. This also includes hypothalamus and optic chiasm.
Chordoma : This brain tumor is in proximity to significant structures and it also cannot be successfully treated with the help of traditional radiation therapy. Cyberknife is considered as superior treatment option as it can accurately conform to tumor shape.
Primary Brain Cancers such as Oligodendroglioma, Astrocytoma, Glioblastoma Multiforme or Glioma : The survival rate and also the quality of life can be improved by stereotactic radiosurgery for those patients who are suffering from cancerous brain tumors. These tumors have irregular shape and a Cyberknife can deliver a better treatment to the tumor without causing any damage to surrounding healthy tissues. This treatment may also follow the shape of these irregular shaped tumors.
Hemangioblastoma : This tumor is located in an accessible area that can be successfully treated with the help of Cyberknife in just one treatment session.
Patients who do not want to go through surgical procedure for prostate cancer and also wants to avoid complications related to it can opt for Cyberknife treatment. The outcome of the Cyberknife treatment is same as compared to the surgery but it results in minimal to no complications. Cyberknife is performed on an outpatient basis that does not require any hospital stay. This minimally invasive treatment also results in faster recovery.
Patients who refuse to go through a surgery for pancreatic cancer or who are unable to undergo surgery due to their medical condition or in whom tumor cannot be removed, can opt for minimally invasive Cyberknife system treatment. This treatment is performed on an outpatient basis with no overnight hospital stay and also results in minimal to no side effects.
Cyberknife directly targets the liver tumor by delivering high doses of radiation. Cyberknife system is an ideal choice for those patients who refuse to undergo surgery or in whom tumor cannot be removed or who are unable to go through a surgery due to their medical condition. This minimally invasive treatment offers an alternative to surgery and is performed on an outpatient basis that does not require any overnight hospital stay. It results in faster recovery and minimal side effects unlike conventional surgery.
Cyberknife delivers high doses of radiation that are targeted directly onto the lung tumor. This treatment is a minimally invasive treatment that is an ideal option for those patients who want to avoid surgery or in whom lung tumor cannot be removed or who are unable to undergo surgery due to their medical condition. No overnight stay is required in this treatment as it performed on an outpatient basis and it results in faster recovery time with no or minimal side effects.
Majority of spinal tumors are metastatic meaning that they have spread to different parts of the body such as lungs, breast or prostate. Contoured radiation beams are used in Cyberknife treatment that limits the exposure to tissue surrounding the tumor site. Positive results can be obtained with the help of Cyberknife for treating spinal tumors. Cyberknife offers many benefits over conventional radiation therapy and can also be used in combination with chemotherapy or surgery.
