Proton Therapy for Cancer at Shandong Wanjie Hospital

Proton is a tiny particle that constitutes the nucleus of an atom and carries a positive charge, which can be accelerated by an electric field to reach a very high energy. In the treatment process, the proton gas pedal is used to generate high-energy proton beams. The accelerated high-energy proton beams are injected into the human body under the precise control of the positioning system, and the energy is accurately released into the diseased area to achieve the therapeutic effect, which is called proton therapy. Proton therapy is currently the most effective radiation therapy with the fewest side effects. Proton therapy system is currently the world's most advanced, but also the most expensive large-scale cutting-edge medical equipment.

Proton therapy has at least four advantages over conventional radiotherapy: increased tumor irradiation levels, improved local control rates, fewer complications, and enhanced radiotherapy. All tumor patients who are suitable for radiotherapy are the adaptive population for proton therapy. Especially for early-stage tumor patients, the five-year survival rate of proton therapy reaches more than 80%. Since children are more radiosensitive than adults, traditional radiation therapy can cause radioactive damage to vital organs such as the liver, kidneys, spinal cord, ovaries or testicles. Proton therapy can save vital organs and tissues from damage through precise "targeted blasting" technology, thus solving the problem of radiation therapy for pediatric patients. Proton therapy is also superior for tumors surrounded by vital organs. Proton radiation therapy will become the mainstream of tumor radiation therapy in the next 20-30 years.
