CyberKnife: A Breakthrough in Oncology
What is a cyberknife?
CyberKnife is a robotic radiosurgery system used in the field of cancer treatment. It is a non-invasive method of delivering precise radiation therapy to target tumours in various parts of the body. Here are some key features and aspects of CyberKnife:
- Robotic System: The CyberKnife system consists of a robotic arm that can move around the patient in three dimensions. The CyberKnife system equips this robotic arm with a linear accelerator that delivers high-energy radiation beams to the tumour.
- Image Guidance: CyberKnife utilises advanced imaging technology, such as X-rays and CT scans, to create real-time images of the tumour and surrounding structures. These images help guide the robotic arm's movements and ensure the precise target of the tumour.
- Accuracy and Precision: The CyberKnife system is known for its exceptional accuracy and precision in delivering radiation. Its robotic arm can make continuous adjustments during treatment, tracking the tumour's position and compensating for patient movement, including breathing.
- Non-Invasive Treatment: Unlike traditional surgery, CyberKnife offers a non-invasive treatment option for certain tumours. It delivers high-dose radiation to the tumour while minimising damage to surrounding healthy tissues and organs.
- Versatility: Surgeons use CyberKnife to treat many tumours throughout the body, including the brain, spine, lungs, liver, pancreas, and prostate. It is particularly well suited for treating complex tumours in challenging locations.
- Treatment Planning: Doctors create a treatment plan using advanced software. This strategy determines the precise dosage, number of treatment sessions, and angles for delivering radiation beams.
- Outpatient Procedure: CyberKnife treatments are typically performed on an outpatient basis, meaning that patients can go home the same day. The treatment sessions can spread over several days, depending on the treatment plan.
- Minimal Recovery Time: CyberKnife is non-invasive and generally requires little or no recovery time. Patients can resume their normal activities shortly after treatment.
Please note that the details and capabilities of CyberKnife may vary depending on the version and model of the system, as advancements and improvements are continuously changing in radiosurgery technology.

- Real-Time Image Guidance: Advanced imaging technology, such as X-rays and CT scans, provides real-time imaging of the tumour and surrounding structures. This guidance enables precise tumour tracking and ensures accurate radiation delivery.
- Continuous Motion Tracking: The CyberKnife system tracks the tumour's position during treatment, adjusting the robotic arm's movements to compensate for patient movement, including breathing. This process helps maintain precise targeting throughout the session.
- Non-Invasive Treatment: CyberKnife offers a non-invasive treatment option for certain tumours. It uses highly focused radiation beams to destroy the tumour cells without traditional open surgery.
- Versatility: CyberKnife is versatile in treating tumours throughout the body, including the brain, spine, lung, liver, pancreas, and prostate. Its flexibility and precision make it suitable for complex tumours that may be difficult to reach with other treatment methods.
- Minimises Damage to Surrounding Tissues: The precise targeting of the tumour with CyberKnife helps minimise radiation exposure to healthy tissues and organs surrounding the tumour. This action reduces the risk of side effects and complications.
- Outpatient Procedure: CyberKnife treatments are typically performed on an outpatient basis, allowing patients to return home the same day. The non-invasive nature of the treatment contributes to shorter recovery times than traditional surgery.
- Customised Treatment Plans: Each patient's treatment plan is customised based on their tumour characteristics and medical history. Advanced software assists in determining the precise dosage, number of treatment sessions, and angles for delivering radiation beams.
These unique features collectively contribute to the effectiveness and appeal of CyberKnife as a treatment option for certain tumours, offering patients a minimally invasive and precise alternative to conventional surgery.
How does it work in metastatic bone cancer?
In metastatic bone cancer, Oncosurgeons use CyberKnife as a non-invasive option to deliver targeted radiation therapy. Here's how it generally works:
- Treatment Planning: Before the treatment, the patient undergoes a detailed imaging scan, such as a CT scan or MRI, to precisely locate the metastatic tumours within the bones. Oncosurgeons use images to create a customised treatment plan.
- Tumour Localization: The imaging scans help determine the exact location and size of the metastatic tumours. Oncosurgeons use the information to guide the CyberKnife treatment.
- Robotic Precision: During the treatment, the patient lies on a treatment table, and the CyberKnife robotic arm positions itself around the targeted area. The robotic arm adjusts its position in real-time based on continuous imaging, compensating for any patient movement or tumour shifts.
- Image Guidance: The CyberKnife system uses advanced imaging technology, such as X-rays or cone-beam CT, to continually capture images during the treatment. These images allow for precise tracking of the tumour's position, ensuring accurate radiation delivery.
- Radiation Delivery: Oncosurgeons precisely target high-energy radiation beams at the metastatic tumour within the bone. The radiation damages the DNA of the cancer cells, inhibiting their ability to divide and grow. The goal is to destroy the tumour or slow down its progression.
- Protection of Surrounding Tissues: The CyberKnife system's ability to adjust its position and track tumour movement helps minimise radiation exposure to surrounding healthy tissues and organs. This protection reduces the risk of damage to nearby structures.
- Multiple Treatment Sessions: Typically, CyberKnife delivers treatment for metastatic bone cancer in various sessions spread over several days or weeks. The number of sessions and the radiation dosage depend on the specific treatment plan and the individual patient's condition.
CyberKnife aims to effectively treat cancer by properly targeting the metastatic tumours within the bones with radiation therapy. It minimises damage to healthy tissues in the process. It offers a non-invasive alternative to traditional surgery and can provide palliative care to relieve pain and improve the quality of life for patients with metastatic bone cancer.
How does CyberKnife work in breast cancer?
In the treatment of breast cancer, CyberKnife works by delivering precise radiation therapy to the tumour using the following steps:
- Treatment Planning: Medical professionals create a customised treatment plan by using imaging scans, such as CT scans or MRIs, to map the location and size of the breast tumour.
- Tumour Localization: The imaging scans help precisely identify the location and size of the breast tumour, guiding the CyberKnife treatment process.
- Robotic Precision: During the treatment, the patient lies on a treatment table as the CyberKnife robotic arm positions itself around the breast area. The robotic arm adjusts its position in real-time, actively tracking the movement of the breast or the patient.
- Image Guidance: Advanced imaging technology, such as X-rays or cone-beam CT, provides real-time images during the treatment. This guidance helps ensure accurate tracking of the tumour's position, enabling proper radiation delivery.
- Radiation Delivery: The CyberKnife system directs high-energy radiation beams to the breast tumour, targeting cancer cells. The radiation damages the DNA of the cancer cells, impairing their ability to grow and divide effectively. The goal is to destroy the tumour while minimising harm to surrounding healthy tissues.
- Protection of Healthy Tissues: The CyberKnife system's ability to adjust its position and track tumour movement helps protect healthy tissues from unnecessary radiation exposure. This protection minimises the risk of side effects and potential damage to surrounding structures.
- Treatment Sessions: Oncosurgeons treat breast cancer with CyberKnife in multiple sessions over several days or weeks. The number of sessions and the radiation dosage are determined based on the individual treatment plan and the specific patient needs.
By targeting the breast tumour with radiation therapy, CyberKnife actively contributes to breast cancer while minimising the impact on healthy tissues. It provides a non-invasive alternative to conventional surgical procedures, and doctors use it as either a primary treatment option or as part of a comprehensive treatment approach, depending on the specific characteristics of the breast cancer and the patient's overall treatment plan.
