Radiation oncology is a modality of treatment that involves the controlled use of radiation beams to treat cancer and other symptoms caused by cancer. Radiation therapy also known as radiotherapy is the term used to describe the actual treatment delivered by the radiation oncology team.
Radiation therapy can be delivered to treat a wide range of cancers, and may be used alone or in conjunction with surgery, chemotherapy and other treatments. Radiation Therapy is usually completely non-invasive, and does not require a patient to be admitted for the treatment.
Importance of Radiation Oncology
With constant advances in the technologies used for radiation oncology it results in bringing out successful outcomes for more number of patients, resulting in higher cure rates, causing no damage to the healthy tissues, shorter treatment time and improved quality of life. The latest technologies provide three-dimensional images of tumours that precisely target radiation beams to the cancer, limiting damage to the healthy tissues, along with advances such as real-time imaging which captures the smallest involuntary patient movements, such as breathing.
Radiation Oncology at HCG
At HCG we have the most advanced state-of-the-art technologies assisting our specialists to obtain the best clinical outcomes.
The CyberKnife robotic radiosurgery system is a non-invasive alternative to surgeries for the treatment of both cancerous and non-cancerous tumors anywhere in the body which includes Prostate Cancer, Lung Cancer, Brain Cancer, Spine Cancer, Pancreatic Cancer and Kidney Cancers. CyberKnife uses a movable linear accelerator that is controlled by a computer. The machine rotates so that it can target the tumor from all possible angles which makes the treatment more precise. Cyberknife does not affect the surrounding healthy tissues and also allows the patient to go home in a few hours after the treatment session.
The Tomotherapy H is a state- of- the- art image guided radiotherapy technique which combines the benefits of computed tomography (CT scan) and radiotherapy machines. This helps in imaging the treatment area on a daily basis, pre-treatment, and delivering the radiotherapy exactly to the area intended. It is possible to do this because the machine has the unique ability to deliver thousands of beams let’s travelling in a straight line or in tangents, safely. This cannot be achieved by using any other radiotherapy machine available in this day and age. It’s the regular CT scanning of the treatment area that helps the technologists to make on table adjustments, prior to the delivery of radiation, to correct any shifts that may affect the internal organs.
The TrueBeam is a radiotherapy system which delivers non-invasive radiation to destroy the tumor cells though out the body and minimises exposure of the radiation to the surrounding healthy tissue. Its advanced imaging and treatment models allow the doctor to tailor make treatment plans based on the particular cancer. It synchronises the beam system to an imaging system that adjusts according to the smallest movement of the patient including breathing. The ability of the TrueBem to deliver the high dose radiation at a great speed allows most of the treatment timings to be shortened.
Versa HD is a Versatile, all-in-one system which offers classic radiotherapy to advanced stereotactic precision. Equipped with sophisticated conformal beam-shaping technology and High Dose rate mode delivery, Versa HD™ is designed to provide the precision and speed necessary to deliver advanced stereotactic radiotherapy (SRT) and stereotactic radiosurgery (SRS), techniques that demand the maximum accuracy in tumor targeting and protection of critical structures.
The Agility- synergy is a linear accelerator that enables extremely accurate, image guided adaptive radiotherapy to be delivered safely and in a short period of time. This makes it possible to treat the cancer at any site in the body with great precision to an extent that even non-cancerous conditions like Meningioma, Trigeminal Neuralgia and Acoustic Neuroma can be treated effectively.
Artiste with CT on rails
The Artiste is Asia’s first IGRT with CT-on-rails, making cancer treatment more accurate with minimal side-effects. This provides a high level of accuracy, with a minimal dose to the healthy tissue and maximum does close to the target area. This gives the physicians a broad selection of imaging options and image-based target verification.
Brachytherapy is a type of internal radiation therapy; this therapy allows the physicians to use a higher dose of radiation to treat a smaller area and in a shorter time period with external beam of radiation. Brachytherapy is used to treat wide range of cancers including the Prostate Cancer, Head & Neck Cancer, Cervical Cancer, Skin Cancer, Breast Cancer, Gall Bladder Cancer, Uterine Cancer, Vaginal Cancer, Lung Cancer, Rectum Cancer and Eye Cancer.
Hyperthermia is a medical treatment, which involves heating a part of the body to 42°C and at this temperature the cancer cells can be destroyed with ease through radiation and anti-cancer drugs. Hyperthermia when combined with radiation or chemotherapy can treat tumors on the skin, tumors of the Head & Neck region that may have spread to the lymph nodes.
