How Advanced Is Proton Beam Technology in Singapore Hospitals?

Proton beam therapy is an advanced form of radiation therapy that uses protons as opposed to traditional X-rays to treat cancer. Proton beam therapy's defining advantage is that protons deliver radiation directly to the tumour while exposing less healthy tissue to radiation than that of traditional X-rays. The benefit of proton therapy is based on a unique physical property known as the Bragg Peak, in which protons deposit most of their energy at the tumour site and then stop. Proton Therapy has multiple advantages over conventional X-ray Therapy, including:

Less Radiation Exposure to Healthy Organs
Lower Risk of Short and Long-term Side Effects
Higher Dose Capacity to Treat Difficult Tumours

Proton therapy is valuable for those cancers that are very close to or touching highly sensitive structures in the body, including the brain, spinal cord, eyes, heart, lungs, and reproductive organs.

Proton Beam Therapy in Singapore

Singapore is committed to investing heavily in research, development, and publicly funded Advanced Medical Technology (AMT), including proton beam therapy. This is a technologically advanced way of addressing complex cancer treatments as a future-oriented technology.

A few factors contributing to Singapore's involvement in proton therapy are:

Growth in cancer incidence across Asia.
Increased demand for precision medicine.
Higher survival rates of cancer have led to the need for a safer, long-term treatment option.
Increased need for more advanced paediatric cancer treatment options.
A growing medical tourism and international oncology business presence.

The goal of proton therapy is to provide a long-term solution to improve cancer survival rates while protecting quality of life. Proton Beam Therapy in Singapore offers some of the most advanced systems available worldwide, employing sophisticated technologies.

One such hospital providing Proton Therapy in Singapore is:

Mount Elizabeth Hospital in Novena,Singapore, is one of the region's most advanced proton therapy centres, providing highly accurate cancer therapy using protons to destroy cancer cells while sparing normal cells. Advanced proton therapy enables the delivery of higher, more homogeneous radiation doses via high-energy proton beams to more difficult-to-treat and sensitive cancers than other cancer treatments. Since its inauguration, the Centre has provided care to a diverse patient population, including both adults and children. Additionally, the Centre provides a full range of treatment options, grounded in individualised treatment planning and follow-up care after treatment completion.

Advanced Proton Therapy Technology in Hospitals, Singapore

1. Pencil Beam Scanning (PBS): Pencil Beam Scanning (PBS) is the leading method of proton delivery and the most sophisticated for proton administration. Instead of directing a broad stream of protons, the PBS delivery system "paints" the tumour, layer by layer, with thousands of fine proton beamlets. Some of the advantages of PBS include:

Extremely high precision of proton delivery
The ability to adjust the shape of the dose so that it closely matches the shape of the tumor
Greater protection of the surrounding normal tissue and less chance of damage
A lower amount of ionising radiation is delivered to the patient.

2. Complete Rotating Gantry Equipment: Proton treatment systems for treating patients today have huge rotating heads to produce proton beam walls that can be created from any point around a patient's body. The flexibility of a 360-degree rotating gantry allows physicians to achieve optimal angles, providing maximal coverage of malignant tissue while minimising harm to adjacent healthy tissues. Benefits of these robotic gantries include:

Smooth rotation around the patient
Multi-angle conduct of proton blast
Even distribution of dosage

And reduced exposure of the organs at risk to potentially harmful radiation.

3. Integration of Advanced Imaging Equipment: Precise imaging of tumors utilizing precision imaging techniques is critical to successfully performing proton therapy on a tumor. Singaporean proton therapy providers utilise multiple imaging modalities to accurately locate and treat the tumor using various forms of imaging technologies:

CT and MR image data for treatment planning;
PET/CT image data for metabolic tumour localisation
3D imaging of the patient before treatment

The combination of these imaging technologies enables the physician to accurately position the proton beam to deliver a predetermined dose to the tumour.

4. Motion and Adaptive Therapies and Tracking: Breathing creates fluids that allow the motion of the lung and liver, as well as movement in the abdominal area. Singaporean proton therapy providers have advanced motion tracking systems, based on the following principles:

Use of respiration-gated imaging for establishing proton blast position
Use of breathing-holding techniques
Live tracking of tumors positioned beneath the skin

Developing plans for the response of tumors to perturbations.
Proton therapy is a highly detailed, tailored process that comprises the following steps.

The Procedure of Proton Therapy

Simulation/Planning: Patients' CT/MRI scans are used to create a detailed 3D reconstruction of their tumour and surrounding anatomy. Advanced computer programs will evaluate and identify the most appropriate angles, depths, and distributions for proton beam treatments.
Immobilisation: A custom positioning system has been developed to maintain the patient's complete stillness during treatment, thereby ensuring accuracy within a few millimetres.
Treatment Plan: A team of specialists (including radiation oncologists, physicists, dosimetrists, and other members of the Radiation Oncology team) will work together to develop a plan that delivers the maximum radiation dose to the tumour while minimising dose to healthy tissue.
Image-Guided Delivery: At the beginning of each treatment session, real-time images are used to confirm the patient's position and the tumour's alignment relative to the beam. Once this confirmation is completed, the proton beam is delivered according to the treatment plan.

On average, sessions last 20-30 minutes, whereas the actual treatment lasts only a few minutes.

Proton therapy is most effective for:

Tumours located in the brain
Tumours located in the spine
Head and neck cancers
Tumors in the eye
Cancers in children and young adults
Lung cancer
Liver cancer
Prostate cancer

Tumours that have recurred due to previous radiation treatment
Tumours that require extremely high doses of radiation and/or are in proximity to critical organs.

Advantages of Proton Therapy:

The significant advantages of Proton Therapy provide to patients include:

The ability to reduce normal tissue reaction to radiation
Patients will experience fewer side effects, such as fatigue, nausea, and skin issues
Reduced the chance of secondary cancers developing in the future
Improved long-term quality of life
Children who receive proton therapy can be treated safely, without risk of complications from treatment.
Proton therapy allows for the retreatment of patients who have previously received radiation therapy.

These significant benefits have helped establish proton therapy as a revolutionary treatment option for patients with cancer.

Proton Therapy in Cancer Treatment for Children

Proton therapy is one of the most effective forms of treatment available to children with cancer. Children are more vulnerable than adults to the effects of radiation. Children can suffer a variety of serious side effects from standard forms of radiation treatment, including:

Impact on normal organ development
Cognitive impairment as a result of radiation exposure
Protection of organs while developing
Reduced chance of cognitive impairment
Reduced the chance of developing secondary cancers
Increased chances for long-term survival

In Singapore, the use of Proton Therapy in treating paediatric cancers is of utmost importance.
