MGCH & RI uses the latest technology and processes to deliver the best patient experience possible. You can learn about the technologies which we use in our treatment process.

Treatment of Brain Tumours without surgery!!!

Everyone dreads the diagnosis of a Brain Tumour and its treatment. Brain Tumour does not necessarily mean cancer. Only 50% of the Brain Tumours are malignant, the rest are benign.

Most Brain Tumours need to be treated with surgery or by opening the head. However, now with the new advanced technology the same will soon be a thing of the past. Radiosurgery is a now a proven alternative to conventional surgery in the treatment of Brain Tumours. This procedure is done with techniques known as Stereotactic Radiosurgery and Radiotherapy (SRS/ SRT).

The superior efficacy of Radiosurgery offers lower risk of complications, shorter hospital stay, reduced morbidity and improved quality of life as compared to the conventional methods of treatment. Stereotactic radiosurgery is a nonsurgical, highly precise form of radiation therapy we use to treat cancers of the brain, lung, as well as other types of cancer that require a high degree of precision. With regular radiation therapy treatment, healthy tissue also receives radiation. With stereotactic radiosurgery, our cancer doctors can better focus the radiation on a tumor, so nearby healthy tissue is protected. This is especially important for areas like the lungs and brain.

Using this technology, our doctors are able to reach tumors deep inside the body without the risks of surgery. There is no incision, minimal discomfort, and few of the risks typically associated with surgery, such as infection.

We often perform stereotactic radiosurgery with Varian’s Trilogy™. This system allows us to deliver a 20 percent higher radiation dose, which can shorten treatment times by up to 75 percent.

Our doctors also deliver fractionated stereotactic radiosurgery. In this treatment, the total dose of radiation is divided into several smaller doses of radiation, delivered over several days.

The patient is admitted one day prior to the procedure and has consultation with the Neurosurgeon. & Radiation Oncologist.

Prior to the Radiosurgery, imaging data is obtained in the form of MR scan, CT Scan of brain with an optional Angiography. Treatment planning is done using the imaging data to produce a three-dimensional model of the target lesion and nearby critical structures.

Different treatment plans are evolved and the plan, which is most effective in delivering the desired radiation dose with minimum radiation to the surrounding structures, is selected. The radiation is then delivered using Linear Accelerator and Micro Multileaf Collimator. The patient is discharged the same day in the evening or the next day. Various types of brain tumours can be treated provided certain conditions are met. Various other problems in the brain for e.g. Arteriovenous Malformations, which present with intracranial hemorrhage leading to unconsciousness, epilepsy and paralysis, can be treated by this technique.

This unique facility is now available at MGCH & RI

Stereotactic Body Radiation Therapy (SBRT)

Stereotactic Body Radiation Therapy (SBRT) a form of radiation therapy used to treat tumors in the lungs, liver, pancreas, spine, and other areas of the body with pinpoint accuracy. Prior to treatment, the technology’s specially designed coordinate system precisely locates the tumor to ensure proper placement of tiny seed-like tracking devices. These seeds or pellets track the radiation, and help to spare the surrounding healthy tissues from radiation exposure. During SBRT, we use the Trilogy™ system to deliver concentrated, highly focused radiation treatments. Our doctors may deliver a single high dose of radiation, or a few fractionated radiation doses (usually up to five treatments over a period of days).

SBRT may be a promising option for patients who are not able to undergo surgery. This technology may also be used to treat medically inoperable tumors or tumors that have recurred after previous radiation treatments.

Advantages of SBRT
SBRT uses custom mapping to account for a patient’s anatomy, breathing and organ motion.
SBRT allows us to treat small tumors close to critical organs with less damage to surrounding healthy tissues.
With SBRT, we can deliver a single high-dose radiation treatment, so patients are often able to complete their treatment in a shorter time than with standard radiation treatment.
Other tumor types that may be treated with SBRT include: bile, kidney, prostate, pelvic, and sarcomas.

External beam radiation therapy (EBRT) is a type of radiation therapy that directs a beam of radiation from outside the body onto cancerous tissues within the body. EBRT delivers high-energy rays to tumors, using a special X-ray machine called a linear accelerator. This machine allows radiation to be delivered from any angle and shapes radiation beams to the contour of the tumor. External beam radiation is distinguished from internal radiation therapy, which places radioactive materials directly into or near a tumor via injection, a catheter, or other methods.

Advantages of External Beam Radiation Therapy
Our state-of-the-art radiation technology enables our oncologists to more accurately target a tumor with higher doses of radiation, while minimizing damage to your healthy tissue and nearby organs. As a result, EBRT helps to lower the risk of side effects typically associated with radiation treatment.

It’s a fast, painless outpatient procedure. A typical radiation treatment lasts a few minutes. It is administered over a period of six to eight weeks, typically five days a week.
It does not carry the standard risks or complications of surgery, such as surgical bleeding, post-operative pain, or the risk of stroke, heart attack or blood clot.
Unlike chemotherapy, which circulates through the body, ERBT is targeted to the area being treated.

Image Guided Radiation Therapy
Image Guided Radiation Therapy or IGRT, helps to improve the delivery of radiation. With the intention to deliver the best, MGCH & RI uses Image Guided Radiation Therapy (IGRT), one of the most cutting-edge innovations in cancer technology available. The ARTISTE is engineered specifically for Adaptive Radiation Therapy (ART). The linear Accelerator is an integrated imaging and workflow solution that offers a comprehensive portfolio of image-guided and advanced treatment delivery protocols, including in-room CT imaging capabilities and a new multileaf collimator, 160 MLC Respiratory gating systems used to synchronize imaging and close delivery with a patient’s breathing cycle.

IGRT involves conformal radiation treatment guided by a CT scan (called Cone Beam CT), taken in the treatment room just before the patient is given the radiation treatment. The imaging information from the planning CT scan done earlier is overlapped on this Cone Beam CT. With this technique, movements of tumour due to differences in organ feeling or breathing or reduction in size can be tracked Also, even the variation in millimeters in daily positioning of the patient is detected and corrected instantly. Tumors can move, because of breathing and other movement in the body. IGRT allows our doctors to locate and track the tumor at the time of treatment. With this technology, we can deliver precise radiation treatment to tumors that shift as a result of breathing and movement of the bladder and bowels. This also allows our radiation oncologists to make technical adjustments when a tumor moves outside of the planned treatment range. As a result, the radiation treatment is targeted to the tumor as much as possible, helping to limit radiation exposure to healthy tissue and reduce common radiation side effects.

Treatment with “respiratory gating” is used for tumors that move during respiration such as lung and liver

X-ray, a type of high-energy electromagnetic radiation is used for cancer diagnosis, staging and treatment.

In low doses, X-rays can be used to construct images of structures inside the body to detect and stage a tumor. In higher doses X-rays can be used in radiation therapy to help destroy cancerous cells in the body.

An X-ray exam is fast and painless. The images produced appear light or dark, depending on the absorption rates of the different tissues. For example, dense materials, such as bone, show up as white on a film, while fat and muscle appears as varying shades of grey.
