Cyberknife Center for cancerous and non-cancerous Tumor

Cyberknife can irradiate the target using 1200 points in the room, thereby, has the advantage to deliver higher doses to the target while avoiding doses to the normal structures.

Overview
The Chi Mei Cyberknife Center mission is to build a foundation for the advancement of new technology and therapies for the benefit of cancer patients undergoing stereotactic radiosurgery or stereotactic body radiotherapy (SRS/SBRT).
The CyberKnife system is used to treat a variety of cancerous and non-cancerous tumors (malignant and benign tumors) in various parts of the body,  the most common sites include the brain, skull, spine, lung, liver, pancreas, kidney, pelvic and prostate.
The more specific conditions are the following:
  • Arteriovenous malformation (AVM)
  • Acoustic Neuroma 
  • Astrocytoma/Glioma/GBM
  • Cavernous malformations
  • Chordoma
  • Craniopharyngioma
  • Gliomas
  • Hemangioblastoma
  • Hepatocellular carcinoma and liver metastases
  • Meningioma
  • Recurrent Nasopharyngeal carcinomas
  • Oligodendroglioma / Medulloblastoma
  • Pituitary Adenoma (Cushing's Disease)
  • Schwannoma
  • Trigeminal Neuralgia
  • Prostate carcinoma
  • Renal cell carcinoma
  • Early Lung carcinoma and lung metastases

Cyberknife robotic radiotherapy (Accuracy Inc, Sunnyvale, CA, USA) with internal fiducially markers and synchrony respiratory tracking of tumors allows more accurate application by reducing the error margin and normal tissue exposure during therapy, enhancing the chances of treating tumors with limited normal volume available or tumors in close proximity to critical organs. Cyberknife is a frameless whole-body image guided robotic radiosurgery system that has a 6MV linear accelerator mounted on a computer controlled robotic arm and an orthogonal pair of diagnostic X-ray imaging devices. It can irradiate the target using 1200 points in the room, thereby, has the advantage to deliver higher doses to the target while avoiding doses to the normal structures.

Service Procedure
1.Initial consultation
CyberKnife treatments involve a team approach in which several clinicians and specialists participate.  The initial consultation for any CK patient involves a meeting with the patient, a radiation oncologist, and a specialist physician depending on the location and type of tumor being treated.
During this initial meeting, the procedure, as well as its risks and benefits, will be explained to the patient.  The patient should also expect to complete paperwork that is required to move forward with the treatment.  Usually, the initial consultation is done days before the setup procedure.

2.Set-up procedure
Prior to the procedure, the patient is imaged using a CT scan, 0r MRI , to determine the size, shape and location of the tumor.  This may be required even if you have had recent scans; the CyberKnife system requires that scans be obtained using specific protocols which are not normally used for standard diagnostic imaging.

3.Treatment plan
With these new scans, treatment planning begins.  The image data is digitally transferred to the CyberKnife treatment planning computer. Then, physicians and a medical physicist use the scans and sophisticated CyberKnife computer software to plan the details of the radiation delivery.  The goal is to customize the treatment plan to match the desired radiation dose to the identified tumor location while limiting radiation exposure to the surrounding healthy tissue
In some cases, such as liver and prostate carcinoma, patients may need a short stay in the ward ( 3 days 2 night) for the  implantation of  fiducials in or near the lesion prior to treatment with CyberKnife.  Fiducials are small metal markers made out of gold or stainless steel that help track the progress that the CyberKnife is making on removing a tumor or lesion in the body.  They are primarily used for soft tissue tumors in the body (non-head or spine).

4.Treatment delivery
Once the treatment plan has been developed, the patient returns for treatment delivery. During treatment, the patient is fitted with a custom plastic mask (for cranial tumors) or body cradle (for spinal tumors/lesions or other extracranial tumors such as lung or pancreas) and lies comfortably on the treatment table. Generally, no sedation or anesthesia is required.
Then, the CyberKnife system's computer-controlled robot will slowly move around the patient to the various locations from which it will deliver radiation to the tumor. At various intervals, the robot stops and additional x-ray images are obtained, thereby allowing the CyberKnife to track and compensate for small amounts of patient movement.
The entire process is painless and typically lasts 30 to 90 minutes for non-movable lesion such as brain and will took a double amount of time for movable lesion such as lung, liver and prostate. CyberKnife treatment is an outpatient procedure where the patient can usually go home immediately after and return to normal activities. Patients may experience some minimal side effects, but they often go away within the first week.

5.Follow-up
After CyberKnife treatment, the progress of the tumor or lesion must be monitored.  Consultation with your physician and additional imaging with a CT and/or MRI will likely occur within 3 to 6 months of treatment.
Notification
Side effects depend on the location of treatment site, radiation dose, patient performance status and nearby critical organ.
