Apollo Hospitals’ comprehensive care is supported by technology and innovative techniques in High Precision Radiation oncology. High tech radiation oncology is used to treat not only small tumours located in critical areas but is useful in large tumours as well. Experts at Apollo, from a range of disciplines, come together to assess a patient’s suitability for the therapy, which is delivered using a number of precisely-targeted stereotactic beams. The 4-dimensional CT scanner is useful in planning treatment to track the tumour’s position as it moves when the patient breathes, guaranteeing a high degree of accuracy and potentially fewer side effects by limiting irradiation of the surrounding normal tissues.
Proton Beam Therapy is one of the most advanced forms of radiation therapy in the world. It uses high-energy proton beam for cancer treatment. The proton beam therapy is a form of particle therapy that will usher in a paradigm shift in cancer treatment. It provides targeted treatment and amplification unlike any other radiation treatment.
Conventional radiotherapy uses high energy X-Rays to treat cancer and certain benign tumors. In doing so, it also damages the healthy tissue. Another disadvantage is the delivery of radiation to the healthy tissue around the tumor. In contrast, proton beam delivers a high dose of radiation only to the tumor maximizing the chances of cure and in turn minimizing the adverse effects to the surrounding healthy tissues.
Furthermore a superlative advantage is its proper dose distribution. A low dose of radiation is released at the body surface which is followed by a sharp burst once it hits the tumor, with negligible radiation travelling beyond the target. The protons can deliver highly conformal radiation to any shape, volume or depth of the tumor by controlling the delivery of their entire energy to the so-called ‘Braggs Peak Region’
Proton Beam Therapy has revolutionized the treatment of several cancers like paediatric cancers, skull base tumors, brain tumors, prostate cancers, and lung cancer to name a few. It becomes a viable option, particularly in cases where treatment options are limited and conventional radiotherapy possess a higher risk to patients. Proton beam therapy has to a large extent, overcome the limitations of conventional radiotherapy. It has the potential to cure more cancers with better quality of life, during and after treatment.
South East Asia’s first Proton Beam Therapy Centre, Apollo Proton Cancer Centre was introduced by Apollo Hospitals, Chennai. India is amongst the few nations in the world which is offering this advanced cancer care treatment.
The True Beam STx system is an innovative solution that is fast and powerful, giving clinicians the ability to navigate the complexities of cancer care with confidence, including challenging cases in the brain, spine, lung, liver and prostate. True Beam combines imaging, beam delivery and sophisticated motion management to accurately and precisely target tumours with speed.
Novalis is the latest technology in radiation oncology which is the most advanced cancer treatment available and is changing the face of cancer treatment. It comes with the advantage of maximizing tumour destruction while minimizing damage to the normal tissues, and offers hope to patients with clinical conditions once considered untreatable. Novalis Tx Radiosurgery incorporates a powerful linear accelerator, which rotates around the patient to deliver treatment beams anywhere in the body from virtually any angle. A set of sophisticated image guidance and motion management tools provide clinicians with detailed information about the shape, size and position of the targeted lesion, guide patient setup and positioning and monitor motion during treatment.
The CyberKnife consists of a lightweight linear accelerator mounted on a robotic arm. Near real-time images allow for patient movement tracking within a 1mm spatial accuracy. The CyberKnife references the position of the treatment target to internal radiographic features such as the skull, bony landmarks or implanted fiducial rather than a frame. The CyberKnife uses real-time X-rays to establish the position of the lesion during treatment and then dynamically brings the radiation beam into alignment with the observed position of the treatment target. The CyberKnife aims each beam independently. When the target moves, the robot detects the change and accommodates it. This treatment system has been used to successfully treat lesions in patients who are otherwise not candidates for surgery or for lesions that are not amenable to open surgical techniques.
Apollo Hospitals is amongst the bare few Tomotherapy centres in India that provides Tomotherapy treatment, a pioneering form of radiation therapy. Tomotherapy uses computed tomography (CT) guided intensity modulated radiation therapy (IMRT) for accurate treatment of cancer by targeting the radiation dose to the exact tumor shape. The state of the art system, used in combination with TomoHelical TM and TomoDirect TM radiation delivery, allows precision in the treatment of different kinds of organ specific cancers.
Tomotherapy treatment in India is fast gaining ground owing to the superior outcomes that it delivers for patients. It allows oncologists to monitor their treatment plan on a daily basis through low dose CT imaging which shows the extent of radiation on the tumor while minimising the effect on healthy tissues. With such close supervision on the planned treatment, it helps get the best results for the patients. Due to its multiple benefits, tomotherapy treatment is now one of the most preferred treatment route adopted by oncologists in India.
Three-Dimensional Conformal radiation oncology (3D-CRT)
A set of CT images is used to identify both the tumour and the critical normal tissue structures that need to be avoided. Then, radiation beams of varying shapes are designed to enter the patient from multiple angles, and hit the tumour while avoiding nearby healthy tissues.
Intensity-Modulated radiation oncology (IMRO)
IMRT is a specialised form of 3D-CRT treatment in which not only the shapes of the radiation beams are varied, but their strengths or intensities as well. This further guarantees that the tumour receives the maximum amount of radiation, while the surrounding normal tissues receive the least possible.
Image Guided Radiation Oncology (IGRO)
This is a cutting-edge technique that combines X-ray imaging and radiation oncology, and allows the daily tracking of changes in both the location and shape of the tumour and healthy surrounding tissues during the course of treatment. IGRT promises to further improve the accuracy of radiation oncology.
High Dose Rate Brachytherapy (HDR)
Brachytherapy involves the use of radioactive sources that are either implanted into the tumour (interstitial brachytherapy) or placed near it, generally in a body cavity (intracavitary brachytherapy) Uterine and cervical cancers are often treated with intracavitary brachytherapy, and prostate cancers can be treated using interstitial brachytherapy. It can also be used to treat early cancers of the tongue and cheek instead of surgery.
Stereotactic Radiosurgery (SRS)
Stereotactic radiosurgery (SRS) is a procedure utilising very accurate targeted radiation in large doses to effectively kill a tumour or destroy a lesion. It is a non-invasive procedure that has been used as an effective alternative to surgery or conventional standard fractionated radiation oncology for treating small tumours.
Stereotactic radiosurgery uses precisely focused radiation beams to treat tumours and other abnormal growths in the brain, spinal column and other body sites. Technology delivers high doses of radiation to the tumour with minimal exposure to the surrounding healthy tissue.
