Everything You Need to Know About SBRT


Radiotherapy, also known as radiation therapy, is a common treatment for cancer that involves using high-energy radiation to destroy cancer cells or slow their growth. 

There are different types of radiotherapy, and the type of radiotherapy used depends on the type and location of the cancer and the patient’s overall health. Some common types of radiotherapy include: 


  1. External beam radiation therapy: This is the most common type of radiotherapy, which involves using a machine to direct high-energy beams of radiation from outside the body into the cancerous tissue. 
  2. Internal radiation therapy (brachytherapy): This radiotherapy involves placing a small radioactive source inside or near the cancerous tissue. 
  3. Systemic radiation therapy: This type of radiotherapy involves using radioactive materials that can be swallowed or injected into the body to target cancer cells throughout the body. 
  4. Stereotactic body radiation therapy (SBRT): This type of radiotherapy delivers high doses of radiation to small, well-defined tumors with extreme precision, often using advanced imaging techniques to guide the treatment. 
  5. Proton therapy: This type of radiotherapy uses high-energy protons rather than X-rays to destroy cancer cells. Proton therapy can deliver a high dose of radiation to the tumor while minimizing damage to surrounding healthy tissue. 
  6. Carbon ion therapy: This is a type of radiotherapy that uses carbon ions, which can penetrate deeper into tissue than traditional radiation, to deliver a more targeted dose of radiation to the cancerous tissue. 


Although this article majorly focuses on Stereotactic body radiation therapy.  

Stereotactic body radiation therapy (SBRT) is a specialized form of external beam radiation therapy that delivers high doses of radiation to small, well-defined tumors with extreme precision. It is also sometimes called stereotactic ablative radiotherapy (SABR). 

The goal of SBRT is to deliver a very high dose of radiation to the tumor while minimizing radiation exposure to the surrounding healthy tissues. This is achieved by using advanced imaging techniques, such as CT scans, MRIs, or PET scans, to precisely locate the tumor and guide the radiation beams. 

SBRT is typically used to treat tumors that are small and well-defined, such as those found in the lungs, liver, pancreas, or spine. It can be an effective treatment option for people who are not good candidates for surgery, or for those who prefer a non-invasive treatment option. 

SBRT is usually delivered in a few (usually 1-5) high-dose treatments, compared to conventional radiation therapy, which is typically delivered in lower doses over several weeks. This shorter treatment course may be more convenient for patients and may help reduce the risk of side effects. 

However, SBRT can still cause side effects, such as fatigue, skin irritation, and nausea. Patients need to discuss the potential risks and benefits of SBRT with their doctor before starting treatment. 


Which type of cancer can be treated with SBRT? 

Stereotactic body radiation therapy (SBRT) can be used to treat a variety of cancer types. It is most commonly used to treat tumors that are small and well-defined, such as those found in the lungs, liver, pancreas, or spine. 

SBRT is effective in treating early-stage non-small cell lung cancer, as well as certain types of liver cancer and pancreatic cancer. It may also be used to treat spinal tumors, prostate cancer, and other types of cancer. 

In general, SBRT is most effective when the tumor is small and has not spread to other parts of the body. It may be used as the primary treatment for early-stage cancer or as a complementary treatment alongside other cancer treatments, such as chemotherapy or surgery. 

Patients need to talk to their doctor about whether SBRT is a suitable treatment option for their specific type and stage of cancer. 


Can it be used to treat illnesses other than cancer?

While stereotactic body radiation therapy (SBRT) is primarily used for the treatment of cancer, it may also be used to treat certain non-cancerous conditions, such as certain types of benign tumors or vascular malformations. 

For example, SBRT may be used to treat certain types of benign brain tumors, such as meningiomas, acoustic neuromas, and pituitary adenomas. It may also be used to treat arteriovenous malformations (AVMs), which are abnormal tangles of blood vessels in the brain. 

In addition, SBRT may be used to treat certain types of spinal conditions, such as spinal cord compression or painful vertebral tumors. 

However, it is important to note that SBRT is primarily a cancer treatment, and the use of SBRT for non-cancerous conditions is still relatively uncommon. Patients should talk to their doctor about whether SBRT is a suitable treatment option for their specific condition. 


What are the benefits of SBRT? 

There are several benefits to using stereotactic body radiation therapy (SBRT) to treat cancer. These include: 

  • High precision: SBRT uses advanced imaging techniques to precisely locate the tumor and guide the radiation beams, which allows for very high precision in targeting the tumor. This helps to minimize radiation exposure to surrounding healthy tissues and organs. 
  • High dose delivery: SBRT delivers a very high dose of radiation to the tumor in a short amount of time, which can be more effective at killing cancer cells than conventional radiation therapy. 
  • Fewer treatment sessions: SBRT typically requires fewer treatment sessions than conventional radiation therapy, which can be more convenient for patients and may also reduce the risk of side effects. 
  • Non-invasive: SBRT is a non-invasive treatment option, which means it does not require surgery or anesthesia. 
  • Effective for inoperable tumors: SBRT may be an effective treatment option for people who are not good candidates for surgery or who prefer a non-invasive treatment option. 
  • Reduced risk of complications: SBRT can help to reduce the risk of complications associated with surgery or other invasive procedures. 

It is important to note that not all patients with cancer are suitable candidates for SBRT, and the potential benefits and risks of the treatment should be discussed with a doctor.

radiation therapy for cancer

What is Radiation Therapy/ Oncology? 

Radiation therapy is a method to treat cancer using high-energy beams.

It uses high energy radiation such as x-rays and gamma rays to kill or destroy the cancer cells.

These rays damage the DNA inside the cells and inhibit their property to divide and grow.

This radiation can be delivered through two ways either by a machine called a linear accelerator or by a radioactive source implanted inside the patient’s body on a temporary or permanent basis. 

The main objective of radiation therapy is to eradicate cancer, relieve pain or reduce symptoms in a cancer patient. 

Modern innovations and technology have combined healthcare with machines which made it possible to cure disease like cancer and radiation therapy is one of these methods.

Radiation oncologists are professionals who are skilled to treat cancer via radiation therapy. 

In this article we will look forward to the best radiation oncologists in India and what they do. 


What Do Radiation Oncologists do? 

Oncologists or doctors who are skilled professionals to give radiation therapy to a cancer patient are radiation oncologists.

Radiation oncologists consult often with medical oncologists, surgeons, and other medical professionals to choose the best course of action for cancer patients. 

Their job involves very crucial decision making for the treatment of cancer patients depending upon the type of cancer, stage of cancer and overall health of the patient.


radiation oncology


Some of the main course of action done by radiation oncologists are: 

A radiation oncologist works incorporation with surgical oncologists and medical oncologists to determine if and how radiation oncology can assist into a patient’s treatment plan.

The radiation oncologist decides how much radiation therapy should be given to a patient and how it should be delivered. 

In order to ensure that patients receive high-quality care throughout treatment, they create and prescribe each cancer patient’s treatment strategy, ensure that each treatment is administered effectively, track the patient’s progress, and make necessary treatment adjustments.

Together with the other members of the radiation oncology team, radiation oncologists also assist in identifying and treating any side effects of radiation therapy.

Radiation Vs. Surgery For Cancer Treatment

Cancer, as we all know is the uncontrollable growth of cells that spreads to other body parts, cause organ failure or death. For the year 2020, India has had 1,392,179 cancer patients, with the breast, lung, mouth, cervix uteri, and tongue being the top five cancer sites. According to the Cancer Statistics Report, 2020, the projected incidence for men was 94.1 per 100,000 people, and for women, it was 103.6 per 100,000 people. In this article, two frequently used treatment options are explained in detail. They are cancer treatment by surgery and radiation therapy.

Cancer treatment by surgery:

Surgery is the most common approach to cancer treatment. It involves removing tumours or areas containing cancer cells. Most cancer patients are scared of this procedure, but doctors strongly advise it, especially if the cancer cells have not begun to multiply in the body. During surgery, the entire area where cancer cells are found is removed.

Surgical procedures are carried out either robotically or manually by the oncologists. Robotic surgery is more commonly used nowadays because it is easier and safer. The term “robotic surgery” refers to a procedure in which a machine enters the body and removes cancer cells. When compared to surgery performed by human hands, it has fewer side effects on the body. At Cancer Hospital in Gurgaon, doctors thoroughly assess the patient’s condition and try to use the best surgical method that cures the patient to the maximum. Treatment options are also determined by the patient’s condition.

Doctors prescribe medications to help the body part heal after surgery. Routine check-ups are also performed to avoid future complications. Depending on the situation, you may be advised to stay in bed and take a rest for a few months or weeks. Supportive care and rehabilitation services for your emotional well-being are also available if needed.

Cancer treatment by radiation therapy:

In India, radiation therapy is the second most popular and safe treatment option for cancer patients. Doctors use high-energy waves to destroy the cancer cells and prevent them from spreading to other parts of the body in this method.

Patients will not experience any of the pain that they would experience during surgery during the course of radiation therapy. However, after the therapy, they are seen to be suffering from pain, anxiety, fatigue, skin rashes, and a variety of other side effects. At centers of radiation therapy for cancer in India, doctors usually recommend radiation therapy when cancer is in its early stages. This method of treatment is most commonly used for children with cancer who are unable to bear the pain of surgery. But, if the condition is serious, doctors will choose the best treatment option after weighing the benefits and drawbacks of various options.

Surgery Vs. Radiation therapy: Which cancer treatment should I choose?

If you’re not sure which of these treatments is right for you, the best thing to do is leave it up to the doctors who are treating you. After considering various factors, they can select the best treatment method for you. If you’re still not convinced by your doctor’s recommendations, you can always seek a second opinion to see what works best for you.

Radiation and surgery both are extremely safe. When it comes to side effects, surgery is more likely to cause serious complications than radiation therapy. Depending on your health condition, your doctor may recommend a combination of treatments to help you recover as quickly as possible. Treatment at a cancer hospital with a multidisciplinary team of cancer care experts and oncologists who can provide an unbiased opinion is always preferable.

Radiation Therapy

Radiation therapy is one of the conventional treatment arms in the cancer world. In this treatment making use of high energy to destroy human body cells is a basic mechanism. This process of Radiation therapy that follows the principle of targeting only the diseased cells in the body is planned in a way that the healthy cells are left intact as far as possible. This planning is done by experts referred to as radiation oncologists.


When Does Radiation Therapy Require?

The conditions in which Radiation therapy is useful for treating are the following:


1. Malignant Conditions:

Radiation therapy is exploited in the treatment of various cancers at some stage with a good predicted outcome like blood cancer, bone cancer, liver cancer, breast cancer, brain cancer, stomach cancer, and skin cancer, are some names that respond well to radiation therapy.


2. Benign Conditions:

Goiter (swelling of the thyroid gland), spurs (bony outgrowths), and several painful and inflammatory diseases of the joints like bursitis and tendonitis, are some examples of benign conditions which respond well when treated with radiation therapy. It is percutaneous here to mention that Radiation therapy is not used as often for benign conditions.

Radiation oncologists are experts as cancer specialists who administer Radiation Therapy and this stream needs a lot of study and precision.

The use of radiation therapy differs from case to case, demographic details, cancer type, stage grade, etc. in the world of oncology treatment radiation therapy is also used in combination with chemotherapy and surgery.

Conventional arm as alone strategy or Primary Mode of Treatment considered to be Radiation therapy> Means that it can be used independently as the primary and first line of treatment.

Radiation therapy in some cases of cancer is given before Surgery because in advanced cases of cancer, the tumor is very big, and as some of the tumors get destroyed, it becomes easier to be removed with surgery.

Radiation therapy in some cases is considered after Surgery the situations when cancer cells are present in adjacent organs or lymph nodes. In such cases, the remnant cancerous tissue is destroyed using radiation therapy.

In conjunction with Chemotherapy, the use of radiation therapy is preferred as a palliative treatment arm. At times, radiation therapy is used to treat palliate symptoms. It aids to shrink the tumor and subsequently reduces the symptoms which occur.


Methods/Techniques of Radiation Therapy

The various types of radiation therapy methods also available in the best cancer hospitals in India have been described below.


1. External Radiation Therapy:

X-Rays, gamma rays, or high-energy particles can be used in this form of therapy.


  • Radiation Therapy external: usually administered in cycles. Each cycle could last for about 1 hour and is repeated daily for about 5-6 days consecutively. This may be repeated as long as the doctor feels necessary.


  • 3D Conformal Radiation Therapy: three-dimensional images of the cancer tissue are created using particular software that helps in visualizing the target organ better.


  • Intensity Modulate Radiation Therapy: it is a form of radiation therapy in which the intensity of the radiation beam can be altered. This ensures that the proper dose of radiation is administered.


  • Conformal Proton Beam Radiation Therapy: this form of treatment is utilizing a proton beam. In the proton beam, the protons are positively charged particles and this is relatively a new form of treatment.


  • Stereotactic radiosurgery: Allows the administration of a large dose of radiation to a relatively smaller area of cancer.


2. Internal Radiation Therapy (Brachytherapy)

It does not make use of radiation beams to treat. The radioactive substance is usually placed in the form of small pellets or seeds during this process – also known as seed implantation.

Radiation Therapy Internal includes interventional stage a for introducing the radioactive pellets inside. Radioactive forms of iodine, cesium, gold, cobalt, iridium, palladium, and ruthenium are usually used in brachytherapy. Preparation for brachytherapy involves deciding the radioactive substance to be chosen.

Internal radiation therapy is classified in the following two manners:


Depending Upon the Duration:

  • Temporary: the radioactive pellets are introduced within the patient’s body and are removed sometime later.
  • Permanent: the pellets are introduced in the patient’s body in or around the target tissue and left there.


Depending Upon the Implantation Site:

  • Intracavity: radioactive material is inserted within a body cavity, the therapy is intracavity brachytherapy
  • Interstitial: the radioactive material may be inserted around the tumor or in the tumor walls. This is defined as interstitial brachytherapy.


The above-described types of radiation therapy can be administered individually or in combination- FOR MORE DETAILS CONTACT THE EXPERT TEAM OF ONCOLOGIST FOR RADIATION THERAPY IN INDIA WITH CANCER ROUNDS
