Proton therapy: Proton therapy is a non-invasive treatment that uses proton radiation to kill cancer cells by preventing them from dividing and growing. Considerations: Proton therapy sends less radiation to healthy brain tissue than standard therapy that uses X-rays.
Patient brain scans show how proton therapy (left) targets brain tumors with minimal radiation going to surrounding tissue and structures, whereas traditional photon radiation (right) can damage surrounding brain tissues and structures.
We've created 10 easy guides to take you through the process of proton beam therapy so you don't have to feel lost in the process.
Fractionated proton therapy led to five years excellent local control rates ranging from 88% to 100% . Fractionated proton therapy usually delivered 54–60 Gy(RBE) in five 1.8–2 Gy daily fractions per week to the tumour volume.
Proton therapy, also known as proton beam therapy, is a radiation treatment that precisely delivers a beam of protons to disrupt and destroy tumor cells. Compared with traditional radiation, protons have unique properties that allow doctors to better target radiation to the size and shape of the tumor.
27 kwi 2022 · Proton therapy has shown promise for brain tumors due to its potential for reduced adverse effects, particularly cognitive dysfunction. Proton therapy has also been evaluated for low-grade gliomas. Initial results suggest high rates of tumor control with acceptable toxicity rates.
There are reports [21–23] of an increasing risk of brainstem, lung, and brain injury treated by proton therapy with increasing LET, suggesting that the proton RBE can exceed 1.1 in vivo. Hence, it is essential to develop an LET-based plan evaluation and optimization method for proton therapy.
