15 Frequently Asked Questions : CyberKnife Treatment in India for Uzbek Patients

Q1 · What is CyberKnife Treatment?

CyberKnife is a form of stereotactic radiation treatment that delivers highly focused radiation to a precisely defined target.

It may be used for selected

• Brain tumours
• Brain metastases
• Spinal tumours
• Selected recurrent tumours
• Selected skull-base tumours
• Selected vascular or neurological conditions
• Other appropriately located lesions

CyberKnife does not involve cutting the brain or body with a conventional surgical knife. The system uses computer-controlled radiation delivery to direct multiple radiation beams toward the treatment target while attempting to limit radiation exposure to surrounding healthy tissue.

Depending on the condition, CyberKnife may be used as

• Primary treatment
• Additional treatment after surgery
• Treatment for residual or recurrent disease
• An alternative to conventional surgery in selected cases
• A fractionated treatment delivered over multiple sessions

Q2 · How much does CyberKnife Treatment cost in Uzbekistan compared with India?

The cost depends on the diagnosis, size and number of lesions, treatment planning, radiation dose, number of sessions, imaging requirements and hospital.

For indicative comparison

• US$1 ≈ UZS 12,200
• US$1 ≈ INR 96

The final cost may depend on

• Type of tumour or lesion
• Size of lesion
• Number of lesions
• Location
• Radiation dose
• Number of treatment sessions
• Treatment planning
• Imaging
• Specialist fees
• Medical physics planning

• Previous chemotherapy
• Patient's general health
• Neurological symptoms
• Radiation tolerance of surrounding organs

CyberKnife may not be appropriate for very large lesions or conditions requiring immediate surgical decompression.

Q7 · What tests are required before CyberKnife Treatment?

Patients may require

• MRI brain or spine
• Contrast-enhanced MRI
• CT imaging
• Neurological examination
• Previous pathology reports
• Previous treatment records
• Blood tests where indicated
• PET-CT or other cancer imaging where appropriate
• Additional disease-specific imaging

The radiation oncology team uses the imaging and clinical information to determine whether stereotactic radiation can be safely delivered.

Q8 · What medical records should Uzbek patients send before travelling?

Patients should provide

• MRI brain or spine images and reports
• CT scans where applicable
• PET-CT reports where applicable
• Previous biopsy reports
• Histopathology reports
• Immunohistochemistry reports where applicable
• Previous surgery records
• Previous radiotherapy records
• Chemotherapy records
• Oncology consultation reports
• Neurosurgery reports
• Medication list
• Recent blood-test reports

Actual imaging files should be shared whenever possible.

Q9 · How does CyberKnife Treatment work?

The treatment generally follows these stages:

Step 1: Specialist Evaluation

The medical team reviews the diagnosis, previous treatment and imaging.

Step 2: Treatment Planning

The target lesion is identified using detailed imaging.

Step 3: Simulation and Positioning

The patient's treatment position is established using the appropriate CyberKnife planning and positioning system.

Step 4: Image-Guided Planning

Imaging is incorporated into the treatment-planning process to define the target and surrounding structures.

Step 5: Radiation Planning

The radiation oncology and medical physics team determines the appropriate radiation dose and treatment arrangement.

Step 6: CyberKnife Treatment

The robotic radiation system directs focused radiation beams toward the target from different angles.

Step 7: Monitoring

The patient is monitored during and after treatment according to the treatment plan.

Step 8: Follow-Up

Follow-up imaging is scheduled to evaluate the treatment response.

CyberKnife is generally non-invasive and does not require a conventional surgical incision.

Q10 · What are the alternatives to CyberKnife Treatment?

Depending on the diagnosis, alternatives may include

• Conventional surgery
• Gamma Knife treatment
• Conventional radiotherapy
• Fractionated radiotherapy
• Observation
• Chemotherapy
• Targeted therapy
• Immunotherapy
• Endovascular treatment for selected vascular conditions
• Medication
• Other specialist-directed treatment

The appropriate option depends on the lesion and patient's clinical condition.

Q11 · What should Uzbek patients ask before accepting a CyberKnife quotation?

• What is the exact diagnosis?
• Is CyberKnife appropriate for the condition?
• What is the size of the lesion?
