CyberKnife Treatment in India

Cancer is the leading cause of death worldwide. The way of treating cancer has also changed dramatically in recent years. The emergence of new treatments has improved the outcomes of patients with cancer.

Radiation therapy is one of the main modalities for cancer treatment. In recent years, radiation oncology has evolved rapidly regarding treatment equipment, imaging, and information technology innovations.

cyberknife treatmentNewer delivery techniques have enabled highly enhanced precision radiation therapy and contributed to improvements in tumor control, with a tremendous reduction in treatment-related side effects, thereby improving the quality of life.

The CyberKnife System is a non-invasive treatment option for cancerous and non-cancerous tumors and other conditions requiring radiation therapy. It includes radiotherapy equipment comprising a robotic arm and a linear accelerator (LINAC).

Previously, radiotherapy was delivered only by conventional methods with an overall treatment time of 1 to 2 months. With the advent of innovative techniques, the same treatment can be completed within a very short span by delivering higher doses with greater accuracy.

Because of the flexibility of the robotic arm, the CyberKnife system can administer radiation therapy for tumors located anywhere in the body, including the brain, head, neck, spine, lungs, liver, pancreas, kidneys, and prostate.

Numerous coplanar and non-coiled angles are used, along with 3D images. It may be an alternative to surgery for patients who refuse to have surgery and with tumors that are inoperable or difficult to operate on. Many cancer patients have benefited from the CyberKnife treatment, which has more than 20 years of clinical evidence to support it.

Patients treated with CyberKnife today would frequently have been untreatable with traditional radiation therapy or surgery in the past. Treatments with the CyberKnife typically require 1 to 5 sessions. It is a daycare procedure, so there is no need for hospitalization.

So, if you are looking for the best CyberKnife treatment in Bangalore or Mumbai in India, contact Prof. Dr. Sridhar PS at HCG Hospital.

    How does the CyberKnife System Function?

    The CyberKnife System is the only robotic system capable of tracking the tumor and the patient’s movement while adjusting the LINAC simultaneously to ensure that the treatment is administered with extreme precision.

    With the aid of an X-ray imaging system, the CyberKnife System can move with the tumor rather than limiting the patient’s mobility. As the name suggests, you might picture a scalpel, anesthesia, and surgery.

    Though, it is a non-intrusive technology. Treatments are typically administered in brief sessions lasting 60 to 90 minutes over 1 to 6/7 days.

    Indications for the CyberKnife Treatment

    The type of pathology in question, the total number of lesions, the size of the tumor, the specifics of the disease, and the patient will influence the number of sessions and length of therapy.

    • Lung Cancer: It is a highly effective treatment for patients with respiratory failure.
    • Liver Cancer: It permits precise removal of liver metastases while sparing normal liver tissue.
    • Pancreatic Cancer: Patients who cannot undergo surgery to remove the pancreatic tumor can benefit from this treatment.
    • Prostate Cancer: Patients with localized prostate cancer most frequently undergo this procedure.

      Benefits of CyberKnife Treatment

      The most sophisticated radiotherapy robot in the world is the CyberKnifesystem. These developments significantly speed up treatments and expand their adaptability to address the full spectrum of potential indications.

      This special ability can target the tumor with a higher dose and greater accuracy. The common side effects of conventional radiation therapy are decreased by avoiding nearby healthy tissue. The advantages also include:

        • It is a non-invasive treatment.
        • It is cutting-edge and provides reliable results.
        • Conventional radiation therapy can take up to six weeks. However, CyberKnife in India takes up to six or seven days.
        • For those who have incurable cancer or, in some cases, for patients looking for an alternative to surgery, this treatment offers new hope and opens doors.
        • There is no room for error because the entire system is robotic.

      How much does CyberKnife Treatment Cost in India?

      This non-invasive procedure is genuinely economical in India compared to other developed countries. The CyberKnife treatment cost in India is less expensive than conventional radiation therapy.

      By submitting all necessary medical documentation for a cancer diagnosis, you can get to know the exact CyberKnife surgery cost in India. You might be given a thorough cost estimate for cancer treatment during the consultation, particularly for CyberKnife treatment in India.

      The CyberKnife System was designed to administer radiation therapy using an external beam:

      SRS delivers several focused radiation beams to treat tumors and other conditions in the brain, neck, lungs, spine, liver, and other body parts. It is a non-invasive procedure, which means no incisions are involved.

      Radiation therapy has advanced technologically, thanks to stereotactic body radiation therapy (SBRT). Because it delivers extremely concentrated radiation over a brief period (days, not weeks), it differs from conventional radiation therapy.

      Small cancers that haven’t spread to other organs are treated with SBRT. Large radiation doses are delivered while limiting the amount of radiation reaching nearby healthy tissue and organs that might harm them.
      SRS and SBRT use three-dimensional image guidance to deliver radiation beams precisely to the tumor. Apart from damaging the DNA of the cancer cell, it also acts on the tumor microenvironment while making the tumor shrink faster by preventing cell multiplication.

      The advent of real-time tumor tracking and high precision makes SBRT an option for retreatment of tumors that have previously received radiation. Moreover, the immunomodulatory effect of SBRT provides tumor control not only locally but also systemic effects like a cancer vaccine.

      SRS/SBRT/SABR is a highly conformal radiation therapy technique that delivers intense doses of radiation to the tumor site with high precision and accuracy in 1-6 fractions. SRS and SBRT are highly effective in treating even tiny but well-defined tumors in inaccessible body parts that are tough to remove surgically.

      SRS/SBRT/SABR can be delivered by different machines like CyberKnife, Gammaknife, Linear accelerators, and Protons. A CyberKnife is one of the most sophisticated precision Robotic Radiosurgery devices used to deliver SRS/ SBRT to various tumors in the body with the help of a real-time tumor tracking system.

      How do SRS and SBRT Work?

      The high-intensity beams project equipment is designed to precisely hit the tumor. These beams only target the cancer cells and have minimal effect on the healthy tissues and organs around the tumor.

      High radiation doses shrink the tumors and prevent the blood vessels from supplying the blood to the cancer cells. This significantly advanced treatment has almost negligible side effects post-therapy.

      Advantages of SRS and SBRT

      • Real-time tumor imaging during delivery of treatment.
      • It can be used as an alternative/complementary to surgery.
      • It can be used in multiple metastatic sites/areas in a single setting.
      • Patients with recurrent cancer or Re-Irradiation can undertake SRS or SBRT.
      • SBRT with Immunotherapy combination is possible and more beneficial in a specific subset of patients.
      • Delivery of treatment from multiple treatment angles sparing the normal tissue.
      • Patients unfit for surgery or not wanting to undergo surgery can also benefit from it.
      • No hospitalization, anesthesia, surgical cuts, blood loss, or other operative complications.
      • Lesser treatment time compared to conventional methods. Better response and tumor control.
