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

Q1 · What Is CyberKnife Treatment?

CyberKnife is a robotic radiation-delivery system used for highly precise stereotactic radiosurgery (SRS) and stereotactic body radiotherapy (SBRT).

It combines

• A compact linear accelerator
• A robotic arm
• Advanced treatment-planning software
• Image guidance
• Target-position monitoring
• Highly focused radiation beams

The system can deliver radiation from multiple angles while the treatment team uses imaging to help position the treatment accurately.

CyberKnife can be used for selected

• Brain tumours
• Spinal tumours
• Brain metastases
• Lung tumours
• Prostate tumours
• Liver tumours
• Pancreatic and other selected tumours
• Recurrent or difficult-to-operate tumours
• Certain non-cancerous tumours and lesions

The exact indications vary according to the CyberKnife system available and the treatment centre.

Q2 · What Is the Cost of CyberKnife Treatment in Iraq Compared with India?

The cost of CyberKnife treatment depends on the tumour type, tumour size, location, number of lesions, number of treatment sessions, imaging requirements, treatment-planning complexity and hospital. For planning purposes, the exchange rates used below are approximately:

Indicative Cost Comparison

These figures are indicative planning estimates. A final quotation can only be prepared after reviewing the patient's medical records and determining the treatment plan. The quotation may include consultation, treatment planning, imaging, radiation delivery and selected hospital services. Additional investigations, procedures, medicines or treatment sessions may increase the final cost. CyberKnife treatment can be delivered in one to several sessions depending on the target and prescribed treatment plan.

Q3 · Which Indian Cities Can Iraqi Patients Consider for CyberKnife Treatment?

CyberKnife availability is more specialised than general radiation therapy. Iraqi patients should confirm the exact technology and treatment team before travelling.

CyberKnife availability can change between hospital campuses. Patients should confirm that the specific hospital and campus has the required CyberKnife system before booking travel.

Q4 · Which Hospitals in India Can Iraqi Patients Consider?

The following hospitals form part of the established India guide structure. The exact availability of CyberKnife must be confirmed with the selected hospital because not every hospital listed necessarily has CyberKnife technology.

Important: This is the established broad hospital list used for the India patient guides. It should not be interpreted as confirmation that every hospital listed provides CyberKnife. Current technology, treatment availability and the appropriate specialist should be confirmed directly with the selected hospital before travel. Current published information identifies CyberKnife or stereotactic radiosurgery services at selected Indian centres, including facilities in Chennai, Bengaluru, Delhi NCR and Mumbai.

Q5 · What Conditions Can Be Treated with CyberKnife?

CyberKnife can be used for selected cancerous and non-cancerous tumours and lesions.

Depending on the treatment centre and clinical indication, it may be considered for

• Brain tumours
• Brain metastases
• Acoustic schwannoma
• Other selected schwannomas
• Selected pituitary tumours
• Spinal tumours
• Selected lung tumours
• Prostate cancer
• Selected liver tumours
• Selected pancreatic tumours
• Other carefully selected tumours
• Selected recurrent tumours

CyberKnife may also be used for selected patients who have previously received radiation, although re-irradiation requires careful specialist assessment. Apollo's current CyberKnife information specifically describes treatment for selected benign brain tumours, including acoustic schwannoma, non-acoustic schwannoma and pituitary adenomas, as well as tumours in multiple body locations.

Q6 · When Might an Iraqi Patient Be Recommended CyberKnife?

CyberKnife may be considered when a patient's tumour or lesion is suitable for highly focused stereotactic radiation.

Possible situations include

• A tumour that is difficult to access surgically
• A tumour close to important structures
• A small or appropriately defined tumour
• Selected brain metastases
• Selected spinal tumours
• Selected recurrent tumours
• Selected patients who cannot undergo conventional surgery
• Selected patients requiring highly focused radiation
• Selected cases where fractionated stereotactic treatment is preferred

The decision should be based on the patient's complete imaging, pathology and previous treatment history. CyberKnife is not automatically a substitute for surgery. In some cases, surgical removal may provide a more appropriate treatment option.

Q7 · What Technology Is Used During CyberKnife Treatment?

CyberKnife combines robotic movement, radiation delivery and image guidance.

The main components may include

• Robotic linear accelerator
• Real-time image guidance
• Treatment-planning software
• Target localisation
• Motion tracking
• Multiple radiation-beam angles
• Stereotactic treatment planning
• Dose optimisation
• Image-guided radiation delivery

The CyberKnife S7 system described by Apollo uses a linear accelerator mounted on a robotic arm and incorporates image guidance and motion synchronisation to adapt treatment delivery to target movement. For selected body tumours, motion management can be particularly important because organs may move with breathing.

Q8 · What Medical Reports Should Iraqi Patients Send Before Travelling to India?

For a preliminary CyberKnife assessment, Iraqi patients should ideally provide

• Recent MRI scans, where relevant
• MRI reports
• CT scans and reports
• PET-CT reports, where applicable
• Previous biopsy reports
• Histopathology reports
• Previous operation reports
• Previous radiotherapy records
• Previous chemotherapy or systemic treatment records
• Current medication list
• Recent blood-test reports
• Previous discharge summaries
• Oncology consultation reports
• Details of current symptoms
• A summary of previous cancer treatment

For brain and spine cases, the actual imaging files can be particularly important because the treatment team needs to assess tumour size, location and proximity to critical structures.

Q9 · What Is the Usual CyberKnife Treatment Process in India?

Step 1: Send Medical Records

The patient's imaging, pathology and previous treatment records are reviewed.

Step 2: Specialist Consultation

A radiation oncologist and, where appropriate, a neurosurgeon, medical oncologist or surgical specialist assesses the case.

Step 3: Confirm Suitability

The team determines whether CyberKnife is appropriate and compares it with other possible treatment approaches.

Step 4: Treatment Planning

Detailed imaging is used to define the target and surrounding organs or critical structures.

Step 5: Treatment Setup

The patient is positioned for accurate radiation delivery.

Step 6: Cyberknife Treatment

The robotic system delivers the prescribed radiation from multiple directions.

Step 7: Completion and Observation

Depending on the treatment plan and patient's condition, the patient may be observed for a short period and then discharged.

CyberKnife is generally a non-invasive treatment and does not involve conventional surgical cutting. Treatment may be delivered in one to five sessions depending on the condition and treatment plan.

Q10 · Are There Alternatives to CyberKnife Treatment?

Yes. CyberKnife is one type of stereotactic radiation treatment and may not be the most appropriate option for every patient.

Depending on the diagnosis, alternatives can include

• Conventional surgery
• Microsurgical tumour removal
• Gamma Knife
• LINAC-based stereotactic radiosurgery
• Fractionated stereotactic radiotherapy
• Conventional radiotherapy
• Proton therapy for selected indications
• Chemotherapy
• Targeted therapy
• Immunotherapy
• Hormone therapy
• Observation and active surveillance
• Interventional procedures

The choice depends on the tumour type, size, location, previous treatment, overall health and treatment objective. Different stereotactic radiation systems can have different technical characteristics. CyberKnife is a LINAC-based robotic system, while Gamma Knife uses focused gamma-ray beams.

Q11 · What Should Iraqi Patients Ask Before Accepting a CyberKnife Quotation?

Patients should request a written treatment estimate and clarify

• Exact diagnosis
• Whether CyberKnife is appropriate
• Proposed treatment objective
• Number of sessions
• Radiation dose and treatment plan
• Required MRI/CT/PET imaging
• Radiation oncologist fees
• Neurosurgeon consultation fees, if applicable
• Treatment-planning charges
• Medical physics charges
• Hospital/day-care charges
• Medication charges
• Follow-up imaging
• Additional procedure costs
• What is included in the quotation
• What is excluded
• Cost of additional treatment sessions if required

Patients should also ask whether CyberKnife is being recommended as the primary treatment or as part of a broader treatment plan.

Q12 · How Long Does an Iraqi Patient Need to Stay in India for CyberKnife?

CyberKnife generally requires less physical recovery time than major open surgery. The duration depends on the number of sessions, treatment planning and the patient's condition.

A practical planning schedule may include

• Initial consultation: 1–2 days
• Additional imaging/planning: 1–3 days when required
• CyberKnife treatment: approximately 1–5 sessions depending on the treatment plan
• Post-treatment review: as advised
• Overall India stay: commonly around 5–14 days for an uncomplicated case

Some patients may require a longer stay if they need additional investigations, multiple treatment sessions or treatment for another medical condition. The final travel date should be decided in consultation with the treating medical team.

Q13 · What Is Recovery Like After CyberKnife Treatment?

Because CyberKnife is non-invasive, patients generally do not have the same wound recovery associated with conventional surgery.

Depending on the treatment site and radiation dose, patients may experience

• Fatigue
• Mild headache
• Temporary nausea
• Local discomfort
• Temporary swelling around a treated brain lesion
• Skin effects when appropriate areas of the body are treated
• Treatment-specific neurological symptoms in selected cases

The effects of stereotactic radiation may continue after the treatment session because the biological response of the tumour or lesion develops over time. Patients should continue prescribed medicines and attend all scheduled follow-up appointments. For brain treatment, follow-up MRI is commonly used to evaluate the response, while body tumours may require CT, MRI, PET-CT or another appropriate imaging method.

Q14 · What Follow-Up Will an Iraqi Patient Need After Returning Home?

Before returning to Iraq, patients should collect a complete treatment file containing

• Final diagnosis
• CyberKnife treatment summary
• Treatment dates
• Number of sessions
• Radiation treatment details where provided
• Imaging reports
• Previous pathology reports
• Medication list
• Follow-up recommendations
• Future imaging schedule
• Warning signs
• Contact details for the treating hospital

Follow-up requirements vary according to the treated condition. For a brain tumour, follow-up may involve periodic MRI scans and neurological review. For a body tumour, follow-up may involve CT, MRI, PET-CT, laboratory testing or oncology review. Patients should coordinate with their treating specialist in Iraq whenever possible. Urgent medical assessment is appropriate if the patient develops severe headache, seizures, new neurological weakness, confusion, significant breathing difficulty or another serious or rapidly worsening symptom.

Q15 · Why Do Iraqi Patients Consider India for CyberKnife Treatment?
