IGRT Radiation Therapy in Faridabad

Introduction: A New Era of Precision in Cancer Treatment

Cancer treatment has evolved significantly over the years. Modern medical technology now allows specialists to target cancer cells with greater accuracy while reducing unnecessary radiation exposure to surrounding healthy tissues. One of the important developments in radiation oncology is Image-Guided Radiation Therapy (IGRT), an advanced approach that combines radiation treatment with sophisticated imaging technology.

For patients searching for IGRT Radiation Therapy in Faridabad, understanding how this treatment works, its benefits, and when it is recommended can help them make informed decisions about cancer care.

Unlike conventional radiation approaches that rely primarily on the original treatment plan and external positioning, IGRT uses imaging before or during treatment sessions to verify the position of the tumour and surrounding anatomy. This allows the radiation oncology team to make positioning adjustments when necessary, helping deliver radiation more accurately.

At Metro Hospital, Faridabad, advanced radiation oncology services include image-guided treatment techniques designed to support personalised cancer care.

Patients seeking consultation with the best radiation oncologist in Faridabad can consult Dr. Vikash Kumar, Director & Head – Radiation Oncology, who has extensive experience in advanced radiation treatment and precision-based cancer management. His expertise focuses on selecting appropriate radiation approaches according to each patient’s diagnosis, tumour characteristics, and overall health.

What Is IGRT (Image-Guided Radiation Therapy)?

Image-Guided Radiation Therapy, commonly known as IGRT, is an advanced radiation treatment approach that uses medical imaging to help locate a tumour accurately before or during radiation delivery.

Radiation therapy works by using high-energy beams to damage the DNA of cancer cells, preventing them from continuing to grow and divide. Over time, damaged cancer cells may die, allowing the body to gradually clear them.

However, delivering radiation accurately can be challenging because tumours and internal organs may move or change position.

For example, the lungs move during breathing, the bladder changes size depending on fluid levels, and certain organs may shift slightly between treatment sessions.

IGRT addresses these challenges by using imaging systems to confirm the treatment area’s position.

Depending on the equipment and clinical requirements, imaging may include:

• X-ray imaging
• Cone-beam computed tomography (CBCT)
• CT-based imaging
• Ultrasound guidance
• MRI-based image guidance on compatible systems
• Specialised motion-monitoring and positioning technologies

These images are compared with the original treatment plan so the radiation team can identify changes and make necessary corrections.

The primary goal of IGRT is to improve treatment accuracy while limiting unnecessary radiation exposure to nearby healthy tissues.

How Does IGRT Radiation Therapy Work?

IGRT combines carefully planned radiation delivery with repeated imaging verification. The treatment process involves several important stages.

1. Initial Cancer Evaluation

Before beginning radiation therapy, the radiation oncologist reviews the patient’s medical history, diagnostic reports, imaging studies, biopsy findings, and cancer stage.

The specialist evaluates whether radiation therapy is appropriate and determines the treatment objective.

Radiation may be recommended to eliminate cancer, reduce the risk of recurrence, shrink a tumour before surgery, or relieve symptoms in advanced disease.

Not every patient requires IGRT, and the imaging approach depends on the location and behaviour of the tumour.

2. CT Simulation and Treatment Planning

A planning CT scan, commonly called CT simulation, is performed to map the treatment area.

During this session, the patient is positioned carefully using appropriate immobilisation devices. These may include customised masks, cushions, or body supports to help maintain consistent positioning.

The radiation oncology team uses the images to identify the tumour, surrounding tissues, and nearby organs that require protection.

Additional MRI or PET-CT imaging may sometimes be incorporated into treatment planning.

3. Personalised Radiation Dose Planning

Medical physicists and radiation oncologists collaborate to develop a treatment plan.

The plan specifies the total radiation dose, how it will be delivered, the number of sessions, and the tissues that should receive limited exposure.

Sophisticated planning software helps calculate radiation distribution and evaluate the dose received by the tumour and surrounding structures.

4. Image Verification Before Treatment

Before delivering radiation, imaging is performed to check the patient’s position and the location of the intended treatment area.

The new images are compared with reference images generated during planning.

If differences are identified, the team may adjust the patient’s position or take additional steps before treatment begins.

5. Accurate Radiation Delivery

Once positioning has been verified, the radiation treatment is delivered using the planned technique.

Patients generally remain awake throughout the session. The procedure itself is painless, although maintaining the required position may sometimes feel uncomfortable.

The team monitors the patient from a nearby control room.

6. Ongoing Monitoring and Adjustments

Repeated imaging throughout the treatment course helps the clinical team identify changes in anatomy or tumour position.

In selected situations, significant anatomical changes may require reassessment or modification of the treatment plan.

This ability to verify positioning is one of the reasons IGRT has become an important component of modern radiation oncology.

Key Benefits of IGRT Radiation Therapy

The development of image-guided techniques has improved how radiation oncologists approach complex tumour locations.

Improved Tumour Targeting

IGRT helps confirm the position of the tumour or treatment target at the time of radiation delivery.

This is especially valuable when treating areas affected by breathing, internal organ movement, or positioning differences.

Better Protection of Healthy Tissues

Accurate positioning can help reduce unintended radiation exposure to nearby healthy organs.

This is important when tumours are located close to sensitive structures such as the spinal cord, bowel, bladder, kidneys, or other critical tissues.

However, IGRT does not eliminate all radiation-related side effects.

Greater Treatment Consistency

Cancer radiation treatment often involves multiple sessions delivered over several weeks.

IGRT supports consistent positioning across these sessions and helps the team deliver treatment according to the prescribed plan.

Support for Highly Conformal Radiation Techniques

IGRT is frequently used with advanced approaches such as Intensity-Modulated Radiation Therapy (IMRT), Volumetric Modulated Arc Therapy (VMAT), and stereotactic treatments.

These combinations can help achieve precise dose distribution when clinically appropriate.

Improved Management of Moving Tumours

Some tumours change position as a patient breathes or as surrounding organs fill and empty.

Image guidance provides additional information that can assist in managing these movements.

Personalised Cancer Treatment

Every cancer diagnosis is different.

IGRT allows treatment positioning and verification strategies to be tailored to tumour location, surrounding anatomy, and clinical requirements.

Which Types of Cancer Can Be Treated with IGRT?

IGRT treatment in Faridabad may be considered for several types of cancer, particularly when accurate positioning is important.

1. Prostate Cancer

The prostate may shift slightly because of bladder and rectal filling.

IGRT helps verify its position before radiation delivery, which may support accurate treatment while helping protect nearby organs.

The technique may be combined with IMRT or other suitable radiation methods.

2. Lung Cancer

Lung tumours often move with breathing, making accurate radiation delivery particularly important.

Image guidance can help the radiation team assess tumour positioning and account for respiratory motion.

Some patients may also require specialised motion-management techniques.

3. Head and Neck Cancer

Head and neck tumours may be located near important structures involved in swallowing, speaking, and other functions.

IGRT can help maintain positioning accuracy during radiation treatment.

This is particularly relevant when anatomical changes occur due to weight loss, treatment response, or changes in swelling.

4. Brain Tumours

Precise radiation targeting is essential when treating tumours in or near the brain.

Image guidance may be used alongside stereotactic radiosurgery or fractionated stereotactic radiation therapy, depending on the diagnosis.

5. Breast Cancer

IGRT may be used in selected breast cancer radiation plans to verify positioning and support consistent treatment delivery.

For some patients, techniques such as deep inspiration breath-hold may also be recommended to help reduce radiation exposure to the heart.

6. Gynaecological Cancers

Cervical, uterine, and certain other pelvic cancers may require radiation therapy.

Because pelvic organs can change position, image guidance may be beneficial for accurate treatment delivery.

Depending on the diagnosis, external radiation may also be combined with brachytherapy.

7. Gastrointestinal and Abdominal Cancers

Selected tumours involving the pancreas, liver, rectum, and other abdominal structures may benefit from image-guided radiation.

The approach depends on the cancer type, organ movement, treatment objective, and proximity to sensitive tissues.

Important: IGRT is not automatically required for every cancer. A radiation oncologist determines its suitability based on the individual treatment plan.

IGRT vs IMRT: What Is the Difference?

Patients researching advanced radiation therapy often encounter the terms IGRT and IMRT.

Although they are closely related, they describe different aspects of radiation treatment.

Can IGRT and IMRT Be Used Together?

Yes. IGRT and IMRT are frequently used together.

IMRT helps shape radiation dose distribution, while IGRT verifies the position of the treatment area.

This combination can be particularly useful for tumours near sensitive organs.

The radiation oncologist determines which technologies offer meaningful clinical benefits for each patient.

Is IGRT Radiation Therapy Safe?

IGRT is an established technology used in modern cancer treatment centres.

Its purpose is to improve the accuracy and reproducibility of radiation delivery. However, like every medical treatment, it has benefits and limitations.

Radiation therapy can affect both cancerous and healthy cells, even when advanced techniques are used.

IGRT may help reduce avoidable exposure caused by positioning differences, but treatment-related side effects remain possible.

Some imaging procedures also involve additional low-dose radiation exposure. The clinical team considers this exposure when choosing how frequently imaging should be performed.

The overall safety of treatment depends on several factors, including tumour size, treatment location, radiation dose, previous treatments, general health, and the expertise of the treating team.

A qualified radiation oncologist evaluates these factors before recommending a treatment plan.

Possible Side Effects of IGRT Radiation Therapy

The side effects associated with IGRT are generally related to the radiation delivered to the treatment area rather than the imaging guidance itself.

Possible effects include:

• Fatigue: Feeling unusually tired during or after treatment.
• Skin changes: Redness, dryness, irritation, or tenderness in the treated area.
• Digestive symptoms: Nausea, diarrhoea, or bowel changes when abdominal or pelvic areas are treated.
• Urinary changes: Increased frequency or discomfort in certain pelvic treatments.
• Swallowing difficulties: Possible irritation when radiation involves the head, neck, or chest.
• Localised discomfort: Temporary inflammation in or around the treatment area.

Not everyone experiences these symptoms.

Some side effects develop gradually and improve after treatment, while others can persist or appear later.

Patients should discuss possible short-term and long-term effects with their radiation oncology team before beginning treatment.

How Many Sessions of IGRT Are Required?

The number of radiation sessions depends on the patient’s cancer diagnosis and the prescribed treatment schedule.

There is no single IGRT schedule suitable for every patient.

Some treatments may require only a few sessions, while others may involve daily treatment over several weeks.

Factors influencing the schedule include the type and stage of cancer, tumour location, total prescribed radiation dose, whether radiation is combined with surgery or chemotherapy, and the treatment objective.

Most conventional external-beam radiation courses are delivered on weekdays, although schedules vary.

It is also important to understand that IGRT does not automatically reduce the number of radiation sessions. Its main role is improving positioning and targeting accuracy.

Patients should follow the exact schedule recommended by their radiation oncologist.

How to Prepare for IGRT Treatment

Preparation can make the radiation treatment process more comfortable and consistent.

Before beginning therapy, patients should discuss existing medical conditions, medications, previous cancer treatments, and any concerns with the treating team.

Depending on the area being treated, the radiation oncology team may provide specific instructions about bladder filling, bowel preparation, food intake, or breathing techniques.

Patients should wear comfortable clothing and follow any instructions about removing jewellery or accessories.

During treatment, remaining still is important for positioning accuracy.

If a mask or immobilisation device causes significant discomfort, patients should inform the clinical team rather than attempting to adjust it independently.

A balanced diet, adequate hydration when appropriate, and sufficient rest may also help patients manage treatment-related fatigue.
