CyberKnife Treatment in Delhi

CyberKnife is one of the most advanced non-invasive treatment systems available for brain and spinal conditions. It delivers highly focused beams of radiation with sub-millimetre precision, targeting tumours and lesions while preserving surrounding healthy tissue.

For patients seeking effective treatment without open surgery, CyberKnife offers a compelling alternative, no incisions, no general anaesthesia in most cases, and a significantly faster recovery compared to conventional surgery.

Dr. Vikas Gupta, senior consultant neurosurgeon and neurointerventionalist at Kailash Deepak Hospital, Delhi, provides expert evaluation and co-management of patients undergoing CyberKnife radiosurgery as part of a comprehensive, multidisciplinary treatment approach.

What Is CyberKnife? Understanding the Technology

CyberKnife is a robotic stereotactic radiosurgery (SRS) system, despite its name, it involves no knife and no cutting. It uses a robotic arm to deliver hundreds of precisely targeted radiation beams from multiple angles, all converging on the tumour or lesion with extreme accuracy.

Key features of the CyberKnife system include:

• Robotic Delivery: A flexible robotic arm moves around the patient, delivering radiation from virtually any direction
• Real-Time Imaging: Continuous imaging during treatment tracks the target and adjusts for patient movement, including breathing
• Sub-Millimetre Precision: Targets lesions as small as a few millimetres with minimal margin for error
• Frameless System: Unlike older radiosurgery systems, CyberKnife does not require a rigid head frame, making treatment more comfortable
• Hypofractionation: Treatment can be delivered in 1–5 sessions rather than weeks of conventional radiotherapy

This precision makes CyberKnife particularly valuable for tumours located near critical structures such as the brainstem, optic nerves, or spinal cord.

Conditions Treated with CyberKnife in Delhi

CyberKnife is used to treat a wide range of brain, spine, and body conditions. In the context of neurosurgical care, it is most commonly applied for:

Brain Conditions

• Brain metastases (secondary brain tumours from lung, breast, kidney, melanoma, etc.)
• Acoustic neuromas (vestibular schwannomas)
• Meningiomas (especially small or surgically inaccessible ones)
• Pituitary adenomas
• Arteriovenous malformations (AVMs)
• Gliomas (selected cases, often as adjuvant treatment)
• Craniopharyngiomas
• Trigeminal neuralgia
• Recurrent brain tumours after prior surgery or radiotherapy

Spinal Conditions

• Spinal tumours (primary and metastatic)
• Spinal arteriovenous malformations
• Vertebral metastases causing pain or neurological risk

Other Applications

• Head and neck tumours
• Lung, liver, and pancreatic tumours (in collaboration with oncology teams)

Dr. Vikas Gupta evaluates each case to determine whether CyberKnife, open surgery, or a combination approach offers the best outcome for the patient.

Critical Warning Signs: When to Seek a Neurosurgical Opinion

Consult a specialist promptly if you experience:

• Persistent or worsening headaches, especially in the morning
• New onset seizures or episodes of altered consciousness
• Vision disturbance, blurring, double vision, or peripheral vision loss
• Hearing loss or persistent ringing in the ears
• Facial numbness or pain (particularly if trigeminal neuralgia is suspected)
• Weakness or numbness in limbs
• Balance and coordination difficulties
• Speech or memory difficulties
• Unexplained nausea or vomiting
• A known cancer diagnosis with new neurological symptoms

Early evaluation allows more treatment options, including non-invasive approaches like CyberKnife.

How Is a Patient Evaluated for CyberKnife Treatment?

Before CyberKnife treatment is recommended, a thorough assessment is required to confirm suitability. This typically involves:

• Neurological Examination: Comprehensive assessment of cognitive, motor, and sensory function
• MRI Brain with Contrast: High-resolution imaging to define tumour size, location, and proximity to critical structures
• CT Scan: Often fused with MRI for precise treatment planning
• MRI Spine: For spinal lesions, detailed imaging of the affected vertebral levels
• PET Scan: To assess tumour metabolic activity and extent of disease in metastatic cases
• Histopathology Review: Prior biopsy or surgical pathology results, where available, to confirm tumour type
• Multidisciplinary Team (MDT) Review: Joint assessment with radiation oncologists, neuro-oncologists, and radiologists

This evaluation ensures that CyberKnife is the most appropriate treatment and enables precise treatment planning.

CyberKnife Treatment Options in Delhi

CyberKnife treatment is tailored to the specific condition, tumour characteristics, and individual patient needs. The following approaches are used:

Single-Session Radiosurgery (SRS)

Delivery of the full radiation dose in one session. Used for:

• Small to medium brain metastases
• Acoustic neuromas
• Small meningiomas
• AVMs
• Trigeminal neuralgia

Fractionated Stereotactic Radiotherapy (FSRT)

The total radiation dose is divided over 2–5 sessions. Used when:

• The tumour is larger in size
• The lesion is located near sensitive critical structures (optic nerves, brainstem)
• Fractionation reduces the risk of radiation-related side effects

Spinal Stereotactic Body Radiotherapy (SBRT)

Precisely targeted radiation for spinal tumours and vertebral metastases, delivered in 1–5 sessions. Provides effective pain relief and prevents neurological deterioration without open surgery.

CyberKnife as Adjuvant Treatment

Following surgical tumour removal, CyberKnife may be used to:

• Treat residual tumour tissue
• Reduce the risk of recurrence
• Target surgically inaccessible areas

CyberKnife for Recurrent Tumours

For tumours that have regrown after previous surgery or radiotherapy, CyberKnife offers a precise re-treatment option with minimised radiation exposure to surrounding tissue.

The CyberKnife Treatment Procedure: Step by Step

Before Treatment

• Detailed imaging (MRI and CT) for treatment planning
• Fusion of imaging data by the treatment planning team
• Calculation of radiation dose and beam angles using specialised software
• Patient education and consent
• No fasting or general anaesthesia required in most cases

During Treatment

• Patient lies comfortably on the treatment table, no frame or head fixation required
• The robotic arm moves around the patient, delivering radiation from multiple angles
• Real-time imaging continuously tracks the target, adjusting for any movement
• The patient remains awake and comfortable throughout
• Each session typically lasts 30–90 minutes
• No pain is experienced during treatment

After Treatment

• Patient can return home the same day in most cases
• Mild headache or fatigue may occur temporarily
• Normal activities can typically be resumed within 1–2 days
• Follow-up MRI at 6–8 weeks to assess treatment response
• Regular imaging follow-up every 3–6 months thereafter

CyberKnife vs Other Treatments: How Does It Compare?

CyberKnife is not always the preferred option for large, accessible tumours causing significant mass effect or raised intracranial pressure; surgical removal remains the gold standard. Dr. Vikas Gupta discusses all available options with each patient individually.

Recovery After CyberKnife Treatment in Delhi

One of the key advantages of CyberKnife is the minimal recovery time required compared to open surgery.

• Immediate Post-Treatment: Most patients go home the same day or the following day
• First Week: Mild fatigue or headache may occur; normal daily activities can usually be resumed within 1–2 days
• Radiation Response: The treated lesion does not disappear immediately — it shrinks gradually over weeks to months
• First Follow-up MRI: Typically at 6–8 weeks post-treatment
• Ongoing Monitoring: Regular imaging every 3–6 months to track response and detect any changes
• Return to Work: Most patients return to work within a few days of treatment

Steroids may be prescribed short-term to manage any swelling around the treated area. Dr. Vikas Gupta provides individualised post-treatment guidance and follow-up care.

Cost of CyberKnife Treatment in Delhi

The cost of CyberKnife treatment in Delhi typically ranges from ₹1.5 lakh to ₹5 lakh or more per treatment course, depending on several factors.

Factors That Affect the Cost

• Number of lesions being treated
• Number of treatment sessions required (single vs fractionated)
• Complexity of treatment planning
• Location and size of the tumour or lesion
• Pre-treatment imaging and investigations
• Post-treatment follow-up imaging and consultations
• Whether treatment is combined with surgery or chemotherapy

Patients are advised to obtain a detailed cost estimate during their initial consultation.
