How is a CyberKnife Radiosurgery is different from a Traditional Radiation Therapy Treatment

Whatis the CyberKnife System?

The CyberKnife® Robotic Radiosurgery System is a non-invasive alternative to surgery for the treatment of both cancerous and non-cancerous tumors anywhere in the body, including the head, spine, lung, prostate, liver and pancreas. The treatment – which delivers beams of high dose radiation to tumors with extreme accuracy – offers new hope to patients worldwide.

Though its name may conjure images of scalpels and surgery, the CyberKnife treatment involves no cutting. In fact, the CyberKnife System is the world’s first and only robotic radiosurgery system designed to treat tumors throughout the body non-invasively. It provides a pain-free, non-surgical option for patients who have inoperable or surgically complex tumors, or who may be looking for an alternative to surgery.

What can the CyberKnife System treat?

The CyberKnife® System is a non-invasive alternative to surgery for the treatment of both cancerous and non-cancerous tumors anywhere in the body, including the head, spine, lung, prostate, liver and pancreas. The treatment – which delivers high doses of radiation to tumors with extreme accuracy – offers new hope to patients who have inoperable or surgically complex tumors, or who may be looking for a non-surgical option. To date, more than 100,000 patients have been treated and 244 systems are installed worldwide.

Below is a list of some tumors and lesions that can be treated by the CyberKnife System:

Osteosarcoma
Nasopharyngeal carcinoma
Squamous cell carcinoma
Non-small cell lung cancer
Small-cell lung cancer
Pancreatic cancer
Hepatocellular carcinoma
Prostate cancer
Renal cell carcinoma
Colon cancer
Ovarian cancer
Uterine cancer
Arteriovenous malformation (AVM)

The CyberKnife combines a linear accelerator, robotic arm and image guidance system. The flexibility of the robotic arm allows the CyberKnife to precisely target lesions in areas of the body unreachable by other means. The CyberKnife also is unique in its ability to continually monitor and adjust in near real-time for changes in target location during treatment. Finally, unlike most other stereotactic radiosurgery systems, the CyberKnife is able to locate and treat lesions in the head or neck without the use of an invasive head frame.

There are numerous patient benefits to the CyberKnife system, including:

Non-invasive treatment—no head frames affixed to the skull
No anesthesia
No recovery time
Surgically precise targeting (sub-millimeter clinical accuracy)
100% frameless
Minimal effects to surrounding critical tissues
Robotics adjust to compensate for patient movement
Flexible treatment planning; image acquisition scheduled around the patient’s availability
Complements existing St. Joseph’s radiosurgery technologies
Treatment is typically outpatient, with just one to five treatment days required
Suitable for treatment of many tumors or lesions throughout the body, including soft tissue, spinal, head and neck and intracranial cases
Appropriate treatment for some patients diagnosed with inoperable or untreatable tumors or other lesions

CyberKnife radiosurgery treatment vs traditional radiation therapy treatment?

Traditional radiation therapy typically delivers radiation to a wide field of tissue in the body resulting in the treatment of both the tumor and a large amount of surrounding healthy tissue. This is necessary because traditional radiation therapy systems did not account for tumor motion and were therefore much less accurate. These wide radiation fields increased the possibility of damage to normal tissue, increasing the risk of side effects following the radiation treatment. To reduce the number of side effects, clinicians were forced to rethink the way traditional radiation therapy was delivered. As a result, the overall radiation dose was reduced and the number of treatments was divided into 30 to 40 sessions, delivered over a period of weeks.

Radiosurgery devices, such as the CyberKnife Robotic Radiosurgery System, were designed to deliver radiation with extreme accuracy, targeting the tumor with minimal damage to the surrounding healthy tissue. The accuracy of the CyberKnife System allows clinicians to deliver very high doses of radiation safely because the size of the radiation field is smaller and only includes the tumor and a small amount of surrounding tissue. This allows for less damage to surrounding healthy tissue and for clinicians to complete treatment in 1 to 5 days vs. the weeks it takes traditional radiation therapy.

Advantages of CyberKnife Radio Surgery in India

Cyberknife surgery in India

Cyberknife is the world's first and only robotic radiosurgery system which treats tumours anywhere in the body without any surgery. Though it is called Radiosurgery or Cyberknife- No knife is used for incision and no surgery is performed to treat the tumours. A new hope for patients who have inoperable or surgically complex tumors, or who may be looking for a non-surgical option. Cyberknife radiosurgery is a non –invasive, high-energy radiation treatment that delivers very precise beams of radiation from many angles outside the body. The accuracy of Cyberknife is so precise that radiation can be 'matched' to the shape of small complex tumors, even those located near critical organs. This ability allows Cyberknife to treat many lesions including some considered inoperable or untreatable with surgery.

The CyberKnife Robotic Radiosurgery System treats both cancerous and non-cancerous tumors anywhere in the body, including the prostate, lung, brain, spine, liver, pancreas and kidney.It provides a pain-free, non-surgical treatment to the patients with complex tumours which are un operable or too risky to be operated and to the patients who are looking for an alternative to surgery. To date, more than 100,000 patients have been successfully treated and more than 150 systems are installed worldwide.

Cyberknife Treatment Procedures

Cyber knife treatment works in mainly two ways. In the first methodology, lightweight radiation delivery equipment is inserted on a multi-jointed robotic arm, so that it can be easily reach tumors in any part of the body. In the second method, the technique uses image guidance system, which allows the Cyberknife therapy to track and allocate the tumor.

CyberKnife uses image guidance and robotics to maintain a high degree of precision and is particularly useful for tumors that are close to critical structures.

The biggest advantages which the Cyber knife treatment offers are that no anesthesia is required, no hospitalization and no cuts or incisions at all. This means that there is no recovery time and everyday activities can be resumed immediately. Also, the treatment is undertaken in 1 to 6 sessions, which can be performed on either the same day or different days, as per the patient's convenience.

What does Cyber knife Surgery Treat?

The Cyberknife system has FDA clearance for treatment of tumors in any location of the body. Cyberknife surgery is administered for both cancerous and benign tumors. All stages, from I until IV (metastases) can be treated. Following are treated using Cyberknife system:

Cancers involving the brain
Lung cancers
Pancreatic cancers
Metastatic liver cancers
Cancers involving the spine
Benign brain tumors
Malformations of blood vessels within the brain
Trigeminal neuralgia
Metastatic orbital tumors, orbital lymphomas and orbital inflammations (tumors or inflammations around the eye)

Advantages of CyberKnife Radio Surgery Over Other Radio surgery Methods

The CyberKnife system is able to locate tumors within the body without the use of an invasive stereotactic headframe used with other systems. This is much more convenient and less traumatic for patients.
While other forms of radiosurgery can only treat tumors in the head, Cyberknife can treat tumours anywhere in the body- brain, spine, liver, lungs, pancreas, kidney or prostrate.
While other forms of radio surgery treatment techniques need rigid head-frames screwed to the patient's head for controlling movement, which is painful and cumbersome for the patient, CyberKnife does not require such extreme procedures to keep patients in place, and instead relies on sophisticated tracking software, allowing for a much more comfortable and non-invasive treatment.
The CyberKnife System can essentially "paint" the tumor with radiation allowing it to precisely deliver treatment to the tumor alone, sparing surrounding healthy tissue.

Cyberknife Cancer Treatment in India: A New Hope for Patients

There was a time, when cancer patients from India were flying to other countries for their treatment but thanks to hospitals in India, which has introduced the most advanced Cyberknife Radio Surgery System in Asia Pacific, things are now the other way around. Now, cancer patients from all across the world can receive Cyberknife cancer treatment in one of India's best hospitals.

Cyberknife surgery in India is offered at a greatly reduced costs. But this does not mean a compromise on the quality at all. Also, due to the reduced costs, patients can opt for a longer hospital stay. When going in for a Cyberknife treatment in India, there is one thing which you should keep in mind. Hospitals in India usually require a PET CT scan reports or MRI images before they can provide an estimate and accept the patient.
