What is Cyberknife Stereotactic Radiosurgery?

Cyberknife stereotactic radiosurgery is a highly precise, non-invasive radiation therapy used to treat tumors and other medical conditions. Unlike traditional surgery, it doesn't involve any incisions. Instead, it delivers focused beams of high-dose radiation to the target area with sub-millimeter accuracy. Think of it as a surgical knife made of radiation, precisely targeting only the affected area while minimizing damage to surrounding healthy tissues.

The Cyberknife system uses a robotic arm to deliver radiation from various angles, ensuring the tumor receives the maximum dose while healthy tissue is spared. This advanced technology allows doctors to treat tumors that are difficult to reach with conventional surgery, or for patients who are not suitable candidates for surgery due to other health concerns. The real-time tracking and adjustment capabilities of the Cyberknife system also allow for treatment of tumors that move with respiration, such as those in the lung.

The treatment is typically delivered in a few sessions, making it a convenient option for many patients. It’s often performed on an outpatient basis, meaning patients can return home the same day. While the term "radiosurgery" may sound intimidating, it's important to remember that Cyberknife is a non-surgical approach designed to effectively treat tumors while minimizing side effects and improving patient outcomes.

Key Facts:

• Non-invasive – No incisions required.
• Highly precise – Targets tumors with sub-millimeter accuracy.
• Robotic technology – Delivers radiation from multiple angles.
• Outpatient procedure – Patients usually go home the same day.
• Few sessions - Treatment usually completed in 1-5 sessions.

Why is Cyberknife Stereotactic Radiosurgery Performed?

Cyberknife stereotactic radiosurgery is used to treat a variety of cancerous and non-cancerous conditions. It's often considered when traditional surgery is not an option due to the tumor's location, the patient's overall health, or other factors.

Main Conditions/Indications:

• Brain Tumors: Both cancerous and non-cancerous, including meningiomas, acoustic neuromas, and metastases.
• Spinal Tumors: Tumors located in or near the spine.
• Lung Tumors: Early-stage lung cancer and metastases.
• Prostate Cancer: As an alternative or complement to other treatments.
• Liver Tumors: Primary liver cancer and metastases.
• Pancreatic Cancer: Tumors located in the pancreas.
• Kidney Tumors: Tumors located in the kidney.
• Head and Neck Tumors: Tumors in the head and neck region.
• Trigeminal Neuralgia: A chronic pain condition affecting the trigeminal nerve.
• Arteriovenous Malformations (AVMs): Abnormal tangles of blood vessels in the brain.

When Doctors Recommend It:

Doctors typically recommend Cyberknife when:

• The tumor is in a difficult-to-reach location for traditional surgery.
• The patient is not a good candidate for surgery due to age or other health conditions.
• The patient prefers a non-invasive treatment option.
• The goal is to control tumor growth or reduce symptoms while minimizing side effects.
• The tumor has recurred after previous treatment.

Preparation for Cyberknife Stereotactic Radiosurgery

Proper preparation is essential for a successful Cyberknife procedure. Your doctor will provide specific instructions, but here's a general overview of what to expect:

Essential Preparation Steps:

• Initial Consultation: Discuss your medical history and treatment options with a radiation oncologist and/or neurosurgeon. Bring all relevant medical records, including imaging scans and previous treatment summaries.
• Imaging: Undergo CT, MRI, and/or PET scans to precisely map the tumor's size, shape, and location. Angiography may also be required in some cases. These scans are crucial for planning the Cyberknife treatment.
• Fiducial Placement (if needed): For tumors below the neck (e.g., lung, liver, pancreas), small gold markers (fiducials) may be implanted in or near the tumor. These markers help the Cyberknife system track the tumor's position during treatment. This is usually done a few days before the Cyberknife procedure.
• Mask or Body Mold: A custom-fitted mesh mask (for head/neck tumors) or a body mold is created to keep you still during treatment. This ensures the radiation is delivered accurately.
• Medication Review: Inform your doctor about all medications you are taking, including prescription drugs, over-the-counter medications, and herbal supplements. Some medications may need to be adjusted or stopped before the procedure.
• Pre-Treatment Blood Tests: You will likely need to undergo blood tests to assess your overall health and kidney function.

India-Specific Tips:

• Fasting: Follow your doctor's instructions regarding fasting. You may be instructed to avoid eating or drinking after midnight before the procedure.
• Documents: Carry all necessary medical records, including your Aadhar card, insurance information, and referral letters.
• PCPNDT (Pre-Conception and Pre-Natal Diagnostic Techniques Act): If you are a woman of childbearing age, inform your doctor if you are pregnant or suspect you might be. Special precautions may be necessary.
• Arrange for Transportation: Since you may feel tired or drowsy after the procedure, arrange for someone to drive you home.
• Comfortable Clothing: Wear loose, comfortable clothing on the day of the treatment.
• Metal Objects: Remove all jewelry, hairpins, and other metal objects before the procedure.
• Hair Products: If the treatment involves your brain, avoid hair creams or sprays on the day before and the day of the procedure.

What to Expect:

You'll be given detailed instructions on what to do and what to expect during the preparation process. Don't hesitate to ask your doctor any questions you may have. Clear communication is key to ensuring a smooth and successful treatment experience.

The Cyberknife Stereotactic Radiosurgery Procedure

The Cyberknife procedure is typically performed on an outpatient basis, meaning you can go home the same day. Here's a step-by-step overview of what to expect:

Step-by-Step:

1. Arrival and Preparation: You'll arrive at the Cyberknife center and be greeted by the medical team. You'll change into a gown and be positioned comfortably on the treatment table.
2. Mask or Body Mold Placement: If you're being treated for a head or neck tumor, the custom-fitted mesh mask will be placed over your face and secured to the table. If you're being treated for a tumor in another part of your body, you'll be positioned in the custom-made body mold.
3. Imaging and Alignment: The Cyberknife system will use imaging technology (X-rays or CT scans) to precisely locate the tumor and align the radiation beam.
4. Treatment Delivery: The robotic arm will move around you, delivering radiation from multiple angles. You won't feel anything during the treatment. The system continuously monitors your position and adjusts the radiation beam accordingly, even accounting for slight movements.
5. Monitoring: Throughout the procedure, the medical team will monitor you closely via video and audio. You can communicate with them at any time if you have any concerns.
6. Completion: Once the treatment is complete, the mask or body mold will be removed. You'll be monitored for a short period before being discharged.

Duration and Comfort Level:

• Each Cyberknife session can last from 30 minutes to 2 hours, depending on the size and location of the tumor.
• The procedure is generally painless. You may feel some discomfort from lying still for an extended period, but the medical team will do their best to make you comfortable.
• Some patients experience mild anxiety during the procedure. If you're feeling anxious, let the medical team know. They can provide reassurance and support.

What Happens During the Test:

During the procedure, you'll be lying still while the Cyberknife system delivers radiation to the tumor. The robotic arm will move around you, but it won't touch you. The system continuously monitors your position and adjusts the radiation beam accordingly. You won't feel the radiation, but you may hear some buzzing or clicking sounds from the machine. The medical team will be monitoring you closely throughout the procedure and will be available to answer any questions you may have.

Understanding Results

After Cyberknife treatment, it's important to understand how the results are evaluated and what they mean for your ongoing care.

Normal vs. Abnormal Ranges (if applicable):

There aren't specific "normal" or "abnormal" ranges in the traditional sense after Cyberknife. Instead, the focus is on how the tumor responds to the radiation. This is assessed through follow-up imaging scans.

What Results Mean:

• Tumor Control: The primary goal of Cyberknife is to achieve local tumor control. This means that the tumor either shrinks in size or stops growing.
• Stable Disease: In some cases, the tumor may not shrink, but it also doesn't grow. This is considered stable disease and is still a positive outcome.
• Tumor Progression: In a small percentage of cases, the tumor may continue to grow despite treatment. This is considered tumor progression and may require additional treatment options.
• Side Effects: The results also include monitoring for any side effects of the treatment. Your doctor will assess any symptoms you experience and manage them accordingly.

Next Steps:

• Follow-up Appointments: You'll have regular follow-up appointments with your radiation oncologist to monitor your progress. These appointments will typically involve physical exams and imaging scans (CT scans or MRIs).
• Imaging Scans: Follow-up imaging scans are crucial for assessing the effectiveness of the treatment. The frequency of these scans will depend on the type of tumor and your individual situation.
• Symptom Management: Your doctor will provide guidance on managing any side effects you may experience. This may involve medications, lifestyle changes, or other supportive therapies.
• Continued Monitoring: Even if the initial treatment is successful, you'll need to continue with regular follow-up appointments and imaging scans to monitor for any signs of recurrence.

It's important to remember that the effects of Cyberknife treatment occur gradually over days, months, or even years. Be patient and work closely with your medical team to monitor your progress and manage any side effects.
