Radiotherapy Techniques
Proton therapy, VMAT, 3D, Electrons, IMRT, SBRT, SRS
Proton therapy
Proton beam therapy is a form of radiotherapy that uses protons, positively charged particles, to precisely target and treat cancer cells, with minimal exit dose in normal organs, distal to the tumour.

- Minimise dose distal to tumours
- Allows for high doses to tumours
Volumetric Modulated Arc Therapy
VMAT radiotherapy uses x-rays that are shaped to form a conformal treatment target. It is known for its shorter treatment times, increased treatment accuracy, and improved sparing of critical structures, contributing to more effective and patient-friendly radiation therapy.
- Modulated
- Comfortable
Stereotactic Ablative Radiotherapy or Radiosurgery
Stereotactic Radiosurgery (SRS), or ablative body radiotherapy ( SABR, SBRT etc) is a non-invasive and highly precise radiotherapy technique used to treat small tumors or lesions in the brain or other parts of the body. 
- Concentrated
- 1-5 fractions
- Highly accurate
Radiosurgery
Stereotactic Body Radiation Therapy (SBRT) and Stereotactic Radiosurgery (SRS): These are techniques that deliver highly focused, high-dose radiation to small tumors or specific areas within the body. SBRT is often used for the treatment of small, localized tumors outside the brain, while SRS is typically used for brain tumors.
Discover the Power of Proton Beam Therapy in Cancer Treatment
How is proton different different?
Proton therapy is a type of radiation therapy that uses protons rather than traditional photons. Protons have unique physical properties that allow for more precise targeting of tumors, with the potential to reduce damage to surrounding healthy tissues.
Read about which cancers can be treated with proton beam therapy.
When is proton therapy used?
Unlike traditional X-ray radiation, protons deposit their energy more precisely, minimizing damage to surrounding healthy tissues. This precision is particularly beneficial in treating tumors located near critical structures or in pediatric patients, where sparing healthy tissues is crucial. Proton therapy is often employed in various cancers, including brain tumors, prostate cancer, head and neck cancers, liver cancers, and certain pediatric malignancies, with the goal of maximizing treatment effectiveness while minimizing side effects.
Understanding Cancer: Knowledge is Power
Radiotherapy technology is very advanced these days, leveraging complex computer software and complex linear accelerator to deliver treatment ranging from proton therapy, to high dose ablative radiosurgery, to radionuclides sources placed directly near tumours (brachytherapy).
Radiotherapy, also known as radiation therapy, uses high doses of radiation to kill or damage cancer cells, preventing them from growing and dividing.
Brain Tumours
Benign brain tumours like acoustic neuroma and craniopharyngiomas can be controlled safely with moderate doses of radiotherapy. Brain tumours like gliomas can be managed with surgery, chemotherapy and radiotherapy. Small brain metastases can be eradicated with stereotactic radiosurgery.
Sarcomas
Radiotherapy is delivered to the surgical bed with image-guidance treatment with pre-operative MRI guidance. For selected tumours near critical organs, proton therapy can provide safe and high probability of control, e.g. chordoma. For unresectable tumours, high doses of proton therapy can be used to cure.
Process of radiotherapy
- After consultation, the patient will undergo a series of procedures.
- Radiotherapy preparation is a painless process, involving immobilisation and image-acquisition (simulation).
- The radiation oncologist then draws out the tumour to be treated and normal organs to be avoided.
- A physicist or radiation therapy then uses advanced computer algorithms to calculate the doses and most optimal angles for treatment.
- The radiation therapist will set the patient up and take on-couch images to ensure accuracy.
- While on the couch, the patient lie still for about 30 minutes or less. The process is painless.
Talk to your radiation oncologist about your treatment plans to discuss probabilities of short and long term toxicities, with mitigation strategies.

Should proton beam therapy for breast cancer be considered?
Proton beam therapy (PBT) is emerging as a promising option in the treatment of breast cancer, particularly in scenarios where minimizing radiation exposure to surrounding organs is crucial. While PBT offers these advantages, it comes with higher costs and logistical considerations. Ongoing research and clinical trials aim to refine patient selection criteria and evaluate its cost-effectiveness, ensuring that the benefits outweigh the challenges.
