Intensity-modulated Radiotherapy (IMRT)

Intensity-Modulated Radiotherapy in Dhakuria

The application of IMRT involves shaping radiation beams to accurately target cancerous areas while minimising exposure to surrounding healthy tissue. IMRT, also known as Intensity-Modulated Radiotherapy, is a form of advanced radiation treatment used for both cancerous and non-cancerous tumours. This technique utilises linear accelerators to precisely deliver radiation to the tumour while limiting the impact on nearby healthy tissue. By shaping the radiation beams to closely fit the cancerous area, IMRT achieves high accuracy in targeting the tumour. Traditional radiation treatments deliver radiation in a linear manner, which poses a challenge due to the irregular shape of tumours. Consequently, the radiation may impact not only the tumour but also the surrounding healthy tissue. IMRT technology allows radiation oncologists to precisely and accurately target a tumour, potentially resulting in reduced side effects and increased success rates in curing the disease.

FAQ's

Intensity-modulated radiotherapy (IMRT) is an advanced form of radiation therapy used to treat cancer. It allows doctors to precisely target cancerous tumours with high doses of radiation while minimising exposure to surrounding healthy tissues. IMRT uses sophisticated computer software to modulate, or adjust, the intensity of the radiation beams, shaping them to conform to the shape of the tumour.

In contrast to traditional Radiotherapy techniques, IMRT uses a safer approach to administering stronger and more efficient radiation doses to tumours while reducing the impact on surrounding healthy tissue. This is accomplished by reducing the proportion of radiation absorbed by healthy tissue compared to that absorbed by the tumour.

Initially, a CT scan will be performed to map your tumour in three dimensions. Next, using cutting-edge computer programmes, a group of radiation therapy specialists, comprising physicians and physicists, will calculate and apply radiation to the tumour directly from various angles.

A radiation therapist will position you on a treatment table at the start of each treatment session, marking certain areas of your skin to indicate where the radiation will be administered. Sessions of treatment are painless.

During treatment and recovery, it is important to give your body ample rest. Aid in the healing process by maintaining a nutritious diet and staying well-hydrated. Your skin may be impacted based on the area being treated, such as increased sensitivity to sunlight. To properly care for sensitive skin, follow these steps:

  • Wear comfortable, loose-fitting clothing and opt for personal care products without harsh chemicals or fragrances.

  • Do not use heating pads or ice packs directly on skin that has been exposed to radiation.

  • To prevent sun damage, it is important to wear loose and light clothing when outdoors and to also apply sunscreen to any exposed skin.

Tumours and malignancies that can be treated with IMRT include:

  • Brain tumours
  • Breast cancer
  • Gynaecological cancer
  • Carcinoma of the head and neck
  • Lung cancer
  • Prostate cancer

Depending on the patient's condition and the kind, location, and size of the tumour, many treatment sessions are typically needed for IMRT. The patient lies on a table at the start of the session. The doctor exits the room once they are positioned. During ‌treatment, the patient is required to remain motionless. The length of the sessions will be between fifteen and thirty minutes. Although the posture they sleep in may cause discomfort, there is typically no pain experienced during the actual therapy.

IMRT is a beneficial treatment method that offers numerous advantages, such as:

  • Precision: By delivering highly targeted radiation, Intensity-Modulated Radiation Therapy (IMRT) minimises damage to nearby healthy tissues

  • Effectiveness: By enabling larger radiation doses to be targeted at the tumour, it improves tumour control

  • Reduced Adverse Effects: When compared to conventional Radiation Therapy, there is a lower chance of problems and adverse effects

  • Adaptability: Capable of accommodating intricate tumour sizes and forms

  • Quality of Life: By lowering treatment-related toxicity, it improves patient outcomes and quality of life

Several factors, such as your radiation dosage, the frequency of treatments, the body area that was exposed to radiation, etc., affect how long it will take you to recover. While some people require a month or two to recover, many who have adverse effects do so in a matter of weeks. Depending on your situation, your radiation oncologist will go over potential side effects and what to anticipate during your recuperation.

Although IMRT is a highly advanced and successful method for treating cancer, it does have a few limitations, such as:

  • Complexity: Time-consuming planning and delivery are necessary due to the need for specialised equipment and highly trained workers

  • Cost: Typically more because additional staff and specialised equipment are required

  • Treatment Duration: Due to its complexity, a longer term of treatment is required

  • Adverse Effects: Weariness, skin irritation, and other adverse effects from Radiation Therapy may still affect some individuals

  • Limited Availability: Not readily available everywhere, which can force patients to travel to receive care
