“…4,6,10,19 Particle therapy, such as carbon ion therapy (CIT) and proton therapy (PT), can deliver high-dose radiation to tumours while minimizing the dose delivered to organs at risk because of its precise dose distribution compared with conventional photon therapy. [22][23][24][25][26][27][28][29][30][31][32] Particle beams possess a physical characteristic called the Bragg peak, which emits a relatively low dose near the body surface and releases the maximum energy just before it stops in the depth. Recently, several investigators have reported on the efficacy of CIT for sacral chordomas, describing high LC rates and low toxicities.…”
