Proton / Heavy Ion Therapy Center

Proton and heavy ion therapy is a type of particle radiotherapy that utilizes physical properties such as the Bragg peak to reduce the radiation dose to normal tissues in certain tumors. It is commonly used for pediatric tumors, skull base tumors, eye tumors, some central nervous system tumors, head and neck tumors, prostate cancer, liver cancer, and in re-radiotherapy settings. For patients with specific anatomical locations or those requiring reduced long-term toxicity, particle therapy may reduce the dose to the heart, lungs, digestive tract, and gonads, but indications must be strictly adhered to. Pre-treatment procedures require pathological confirmation, staging assessment, target delineation, and treatment planning, as well as evaluation of respiratory movement, metal implants, and organ movement effects. Current evidence suggests that it can reduce some toxicity in certain tumors, but overall survival benefits still depend on tumor type and stage, and high-quality randomized evidence is limited. Cost, accessibility, and long-term outcomes remain important considerations.
