Personalised, Real-Time Radiotherapy for Safer & More Accurate Cancer Treatment

Adaptive Radiotherapy (ART) is the latest advancement in radiation therapy. It allows doctors to adjust and optimize the treatment plan every day based on how a patient’s body and tumour change during the course of treatment.

What Is Adaptive Radiotherapy?

During cancer treatment, the size and shape of the tumour—and even the patient’s internal organs—can change.

Traditional radiotherapy uses a single plan for the entire treatment course.

Adaptive Radiotherapy goes a step further.

In simple words:

Adaptive Radiotherapy updates and customizes the radiation plan daily to match the patient’s current anatomy, ensuring maximum accuracy and safety.

This makes the treatment more personalised, precise and effective.

⭐ Why Adaptive Radiotherapy Is Needed

The human body is constantly changing, especially during cancer treatment. These changes can affect the accuracy of radiation delivery.

1. Tumour Shrinkage During Treatment

Many cancers shrink while receiving radiotherapy.

If radiation continues to target the original tumour size, surrounding healthy tissues may get unnecessary radiation.

Adaptive RT adjusts the plan to match the new, smaller tumour.

---

2. Weight Loss or Gain

Cancer patients often lose weight during treatment. This alters body shape, making the original plan less accurate.

Adaptive RT corrects for these changes and maintains precision.

---

3. Organ Movement (Breathing, Bladder, Bowel)

Internal organs shift every day due to:

• Breathing

• Eating

• Bladder filling

• Bowel movement

• Natural body motion

These small shifts can make a big difference in areas like:

• Lung

• Liver

• Pancreas

• Cervix

• Prostate

Adaptive RT accounts for daily variations and ensures perfect targeting.

---

4. Swelling or Inflammation

Some tumours or surrounding tissues may swell during treatment.

Adaptive RT modifies the plan to protect critical organs and improve safety.

---

5. Critical Organs Move Closer to the Tumour

Examples:

• Bowel near pelvic tumours

• Eye structures in head & neck cancers

• Spinal cord in spine tumours

Daily adjustments help prevent radiation damage to these vital organs.

⭐ Benefits of Adaptive Radiotherapy

✔ Higher Accuracy Every Day

Daily adjustments ensure millimetre-level precision.

✔ Lower Side Effects

Healthy tissues and organs get less radiation.

✔ Better Tumour Targeting

More effective cancer control and higher cure rates.

✔ Personalized Treatment

Each session is uniquely planned for your body’s condition that day.

✔ Safe for Tumours Near Sensitive Organs

Perfect for prostate, cervix, pancreas, head & neck, brain and abdominal cancers.

✔ Improves Outcomes in Changing Tumours

Especially useful for rapidly shrinking tumours.

Which Cancers Benefit Most from Adaptive Radiotherapy?

✔ Head & Neck Cancers

Tumour shrinkage and weight loss are common. ART improves safety.

✔ Prostate Cancer

Daily bladder and rectum changes require adaptive planning.

✔ Cervical & Female Pelvic Cancers

Bowel and bladder movement affects accuracy.

✔ Lung & Liver Tumours

Breathing causes major shifts in tumour position.

✔ Pancreatic & Upper Abdominal Tumours

Organ motion makes daily adaptation essential.

✔ Large Tumours That Shrink Quickly

Adaptive Radiotherapy Process at I D Cancer Centre

1. Baseline CT/MRI Simulation

Initial scanning to create the first plan.

2. Daily Image-Guidance (IGRT & CBCT)

Imaging before every session.

3. Daily Plan Adaptation

Tumour and organs are re-evaluated; the machine recalculates the best plan.

4. Re-Optimization

The updated plan ensures safe dose distribution.

5. Precision Radiation Delivery

High-quality treatment with accurate alignment.

6. Continuous Monitoring

Oncologists and physicists review images and adjust as needed.

Common Side Effects of Adaptive RT

Adaptive RT reduces side effects compared to standard radiotherapy.

However, mild effects may occur based on the treatment site:

• Fatigue

• Skin redness

• Mild swallowing difficulty (head & neck)

• Loose stools (pelvic)

• Mild urinary irritation (prostate)

• Nausea (upper abdomen)

These are temporary and well-managed by our care team.
