Intensity-Modulated Radiotherapy in India

Intensity-Modulated Radiotherapy (IMRT) is a sophisticated external beam radiation therapy that employs computer-controlled linear accelerators (LINACs) to administer highly focused radiation doses to malignant tumors.  

Who can benefit from IMRT?

IMRT is advised for patients with tumours that are close to sensitive organs or those who need high precision radiation delivery. It is usually used for:

  • Head and neck cancers
  • Prostate cancer
  • Breast cancer
  • Brain tumors
  • Lung cancer
  • Other gynaecological cancers such as cervical cancer
  • Rectal and anal cancers.
  • Esophageal cancer
  • Pediatric cancers

Advantages of IMRT

  • Highly precise targeting of the tumour
  • Minimization of healthy tissue around the tumor is better protected.
  • Less side effects following treatment
  • Capacity to safely deliver higher doses of radiation when warranted
  • Better quality of life while being treated
  • Fewer potential complications in the future
  • Can be used for complex and irregularly shaped tumors.
  • Useful for tumors that are near important organs

IMRT treatment in India

For IMRT, state-of-the-art imaging and computer treatment planning are used to develop a treatment plan specifically tailored to the individual patient. A CT, MRI or PET-CT scan is used to create a three-dimensional map of the tumor. The radiation beam is then split into a number of small beams where the intensity of each can be adjusted.

During treatment:

  • Radiation is administered at many different angles to the patient.
  • The beams are continually shaped by computer-controlled multilevel collimators (MLCs).
  • Various intensities of beams can be used to deliver the most radiation to the tumor while keeping healthy tissues and vital organs unharmed.
  • The use of daily image guidance (IGRT) can help ensure that the patient is positioned correctly before each treatment.

IMRT Treatment Procedure

Initial Consultation

  • The radiation oncologist checks the patient's medical history, biopsy results, imaging scans and past treatments to decide if IMRT is the best treatment.

CT Simulation

  • The patient is then placed in position using special immobilization devices and a planning CT scan is then performed. More MRI or PET-CT scans can be used in conjunction with the CT scan for improved treatment accuracy.

Treatment Planning

  • Tumor definition and delineation of organs at risk by the radiation oncologist. Medical physicists then plan the individual IMRT treatment plan using sophisticated software and subsequently check the plan for accuracy by undertaking detailed quality assurance tests.

Radiation Therapy Sessions

  • Treatment typically is five days a week
  • The entire treatment lasts 5 to 8 weeks depending upon the type and stage of cancer.
  • Each session usually lasts 15-30 minutes of which only a few are spent on the radiation delivery.
  • The process does not cause any pain and does not need to be put under any form of sedation.

Follow-Up Care

  • Pupils are regularly assessed throughout treatment to monitor side effects and response to treatment. Follow up imaging is done after completion to evaluate control of the tumors and recovery.

Factors Affecting IMRT radiotherapy cost India

The following points might influence the cost of IMRT radiotherapy in India:

Type and stage of cancer

  • The treatment plan depends largely on the location, size and stage of the tumor. Complex tumors near critical structures may require more advanced planning and delivery of radiation which may also raise the cost.

Number of Radiation Sessions

  • The treatment is given in several fractions in general. The more sessions a patient needs, the more expensive it will be for them.

Treatment Planning Complexity

  • IMRT treatment plans are customized for each patient based on detailed imaging and computer modeling. The overall cost is dependent on the type of case as those with irregular shapes or multiple targets for treatment may require additional planning and quality assurance.

Advanced Imaging and Simulation

  • Patients receive computed tomography (CT) simulation and in many instances magnetic resonance imaging (MRI) and/or positron emission tomography (PET CT) scans prior to treatment for precise tumor localization. Some extra imaging tests can add to the cost of the treatment.

Radiation Technology Used

The type of radiation equipment and technologies used in conjunction with IMRT may impact costs such as:

  • Image-Guided Radiotherapy (IGRT)
  • Volumetric Modulated Arc Therapy (VMAT)
  • The use of respiratory motion management or gating.
  • Surface guided radiation therapy (SGRT)
  • Adaptive radiation therapy (if available)

These cutting-edge technologies increase treatment accuracy but can also increase the price.

Hospital Infrastructure and Accreditation

  • Treatment in internationally accredited hospitals with cutting-edge linear accelerators (LINACs), advanced treatment planning systems and specialized oncology departments can be more expensive than treatment in smaller healthcare facilities.

Experience of the Oncology Team

  • Radiation oncologists and medical physicists who are well experienced in radiation therapy can charge higher fees at hospitals with experienced radiation therapists and dosimetrists because they are knowledgeable in the field and will provide a quality service.

Preliminary Assessment and Diagnosis Tests

Prior to IMRT, further testing might be needed, including:

  • Blood tests
  • Biopsy review
  • CT scan
  • MRI scan
  • PET-CT scan
  • If appropriate, cardiac and/or pulmonary evaluations.

These evaluations contribute to the overall treatment cost.

Combined with other cancer therapies

Many patients have IMRT in combination with other treatments, including:

  • Chemotherapy
  • Surgery
  • Targeted therapy
  • Immunotherapy
  • Hormone therapy

If more than one treatment modality is needed, the overall treatment cost is increased.

Hospitalization and Supportive Care

  • Typically, IMRT is carried out of the hospital; however, in some instances it may be necessary to treat the patient in the hospital setting because of medical condition or other treatments. The cost can be affected by the cost of hospitalisation, medication, nutrition and symptom management.

Managing side effects

  • Treatment-related side effects might necessitate the use of other medications, nutritional supplements, pain management and supportive therapy which can help with some of the side effects but also contribute to the treatment costs.

Follow-Up Care

  • Post-IMRT follow-up visits, imaging tests and lab tests are crucial to help ensure treatment results and to screen for recurrence. These continuous assessments should be taken into account for the total expenditure on care.

International Patient Services

In addition to the treatment budget, for patients coming from outside, the total cost of treatment might also cover:

  • Medical visa assistance
  • Airport transfers
  • Accommodation
  • Interpreter services
  • Local transportation
  • Caregiver support
  • Most importantly the costs of travel and living.

Best hospitals for IMRT in India

Advanced radiation therapy India

Intensity-Modulated Radiotherapy (IMRT)

  • IMRT beams are shaped to the tumor and have varying intensities. This means that cancer cells can receive higher dose and nearby healthy organ receive less exposure.

Image-Guided Radiotherapy (IGRT)

  • IGRT involves advanced imaging before and during each treatment session to confirm the location of the tumor allowing for very precise delivery of radiation even if the tumor moves.

Volumetric Modulated Arc Therapy (VMAT)

  • VMAT is a type of IMRT where the linear accelerator rotates around the patient delivering and continuously adapting the shape of the radiation beam. It provides faster treatment with greater accuracy.

Stereotactic Body Radiotherapy (SBRT)

  • SBRT provides a high amount of radiation in a small area such as a small tumor in the body in a few sessions. It is frequently utilized in tumors in the lung, liver, spine, prostate, pancreas and kidney.

Stereotactic Radiosurgery (SRS)

  • SRS is a non-invasive therapy. It is most commonly used to treat brain tumors, AVMs, trigeminal neuralgia and some neurological diseases. It offers intense radiation in one or a couple of treatments.

Proton Beam Therapy

  • Proton therapy employs positively charged particles (protons) rather than X-rays enabling the radiation to come to a stop right within the tumor. This greatly reduces the amount of radiation received by nearby healthy tissue and is especially helpful for cancers in children and for tumors located near essential organs.

Adaptive Radiotherapy

  • With adaptive radiotherapy, it is possible to make corrections for changes in tumor size, patient anatomy or weight loss during the treatment course enhancing treatment accuracy.

Radiation Therapy 

  • The radiation beams are delivered in burst and are synchronized with the patient breathing cycle, in this case the radiation beams are delivered only when the patient is in the exhale phase of breathing.

Brachytherapy

  • With brachytherapy, small radioactive sources are placed into or near the tumor. It is typically used for cervical, prostate, breast and some gynaecological cancers.

Total Body Irradiation (TBI)

  • The primary use of TBI is prior to bone marrow or stem cell transplantation to kill cancer cells and to suppress the immune system before transplant.
