Proton Beam


Proton beam therapy (PBT) is a radiation therapy that uses a beam of high-energy protons to kill cancer cells. It is a type of radiation therapy that is becoming increasingly popular as an alternative to traditional radiation therapy.

What are the advantages of proton beam therapy compared to conventional radiotherapy?

Conventional radiotherapy uses high energy X-rays called photons to destroy cancer cells, while proton beam therapy uses beams of protons to achieve the same effect. Unlike conventional radiotherapy, the properties of protons allow them to enter and travel through tissue with minimal dose deposition on the way to the target. When they reach the target, they stop almost immediately, meaning that there is minimal exit dose. This means that proton beam can reduce the risk of serious side effects and the severity of side effects.

    Which patients are likely to benefit most from this treatment?

    In adults, proton beam therapy is used to treat cancers that are located near critical structures such as the optic nerve or spinal cord where conventional X-ray treatment may cause damage. Proton beam therapy can be effective in treating a range of other cancers including head and neck, lung, prostate, breast, bowel, and rectal cancers. It can also be useful to treat cancers that have relapsed after receiving a radical dose of conventional radiotherapy.

    What are the limitations of proton beam therapy?

    From a technical point of view, any change in tissue composition such as variations of the setup of the patient on the treatment machine, lung expansion or rapid shrinkage of the tumour, may affect the target dosage and proton dose to the surrounding structures. The effect of changing tissue composition is not specific to proton beam therapy, but the influence of tissue change on dose is more pronounced with protons than with photons.
