CTOnews.com May 24 news, CTOnews.com learned officially from Tongji Hospital affiliated to Huazhong University of Science and Technology that on May 17, the first "proton" ray in central China successfully went out of the proton treatment center in the Guanggu Hospital of Tongji Hospital affiliated to Huazhong University of Science and Technology, and accurately painted a picture of ink lotus on film.

▲ source Tongji Hospital affiliated to Huazhong University of Science and Technology, which means that the country's first integrated proton system officially leads to a stable high-energy proton beam, Tongji Hospital is the first to usher in tumor proton therapy, and tumor therapy in central China has entered the "proton" era. At the end of June, some of the diagnosis and treatment techniques and services of Tongji Hospital Proton Therapy Center will be put into clinical practice.

According to reports, proton radiotherapy is the most advanced and accurate radiotherapy technology in the world, which has been maturely used in a variety of tumor therapy, can achieve high-dose targeted irradiation of tumors, can be directional "blasting" of tumors.

Tumor radiotherapy is the process of using radiation to "kill" tumor cells through the human body. Compared with commonly used gamma rays and X-rays, proton rays can accelerate rapidly to 70% of the speed of light in the accelerator, reaching cancer cells directly at a speed of 200000 kilometers per second, instantly releasing energy consistent with the shape and depth of the tumor. fixed-point blasting. Proton therapy greatly reduces the symptoms of nausea, vomiting and loss of appetite caused by traditional radiotherapy, and the whole process is painless, especially for elderly patients or patients with weak constitution.

At present, proton therapy is widely used in brain, eye, head and neck, breast, lung, esophagus, liver, rectum, prostate and other malignant tumors, which can effectively prolong the survival time of patients. In addition, many tumor patients who are unable to receive traditional radiotherapy due to side effects are expected to get treatment opportunities. For example, chordoma in the skull base of children is often difficult to be resected completely because of the complex anatomical relationship around the tumor, and the radical dose needed to eliminate the tumor is much higher than that of the surrounding normal tissue, and conventional radiotherapy is difficult to complete radical irradiation. Proton therapy makes these problems easily solved.

Tongji Hospital officials said that in 2022, the first batch of radiotherapy doctors in Tongji Hospital successfully completed a six-month proton therapy training and had a professional proton therapy level. At the end of next month, some diagnosis and treatment projects of Tongji Hospital Proton Therapy Center, such as linear accelerator, 2m PET / CT and so on, will be open to the public. Proton therapy will enter the clinical trial stage at the beginning of 2024. After it is put into operation, it will quickly promote and improve the level of tumor diagnosis and treatment in Central China and fill the gap of proton therapy in the region.
