As early as 1946, Dr. Robert Wilson, a professor of physics at Harvard University, first proposed the concept of proton therapy. More than half a century later, there are currently 60 proton therapy centers in the world, but there are only three medical institutions in China that have the ability to carry out proton therapy.
In order to further expand the international cooperation in proton therapy, on January 12, 2018, the global doctors' organization took the lead in holding the International Frontier Progress Report on Proof Therapy for Children's Oncology and the signing ceremony of the Sino-US Proton Tumor Precision Treatment Cooperation Project. The American Center for Coronary Therapy International Collaboration (hereinafter referred to as the Collaboration Center), and the "Proteo Nephrology Treatment for Children" became the center's preferred collaborative project.
At the seminar, Shen Wenjiang, a professor of lifelong honors in the Department of Radiation Oncology, Peking University School of Medicine, said that the physical advantages of proton therapy have attracted interest and attention from the radiotherapy community and the high-energy physics community. However, the current development trend of proton therapy is still "mixed and mixed." Many experts at the scene agreed with this point of view and throw their own understanding.
Obvious "hi"
"In recent years, the incidence of malignant tumors in children has increased year by year. Traditional treatments - radiotherapy, can cause radiation damage to vital organs such as liver, kidney and spinal cord in children." Danny Indelicato, director of the technical department of the Proton Therapy Center at the University of Florida, said, "Through The targeted fixed-point precision blasting technology for proton therapy can solve the problems in children's radiation therapy, highlighting its superiority in quality of life and IQ protection."
In addition, a number of participating experts believe that proton therapy also has the advantage of reducing the risk of the second primary tumor and saving potential treatment costs. With the advancement of technologies such as proton accelerators, the number of patients not only benefiting from proton therapy will increase. In addition to treating children's tumors, proton therapy can also treat prostate cancer, head and neck cancer, pancreatic cancer, and even some early breasts. Cancer and lung cancer.
"Worry" to be solved
The worry of proton therapy, a recent review published by Nature, is grouped into four categories.
First of all, the cost of treatment is high. Compared to conventional X-ray radiotherapy, proton therapy costs are at least two or three times higher, and are not covered by health care. For example, the current cost of receiving a course of treatment at Shanghai Proton Heavy Iion Hospital is about 200,000 yuan, but reimbursement can only be through commercial insurance channels.
Second, there is a lack of clinical data. There is a vicious circle: in the United States, because of the lack of clinical data in proton therapy that can provide significant efficacy, so that only 30% of patients with insurance costs, and patients can not afford the cost of treatment, the relevant clinical treatment is difficult to carry out Further leads to a shortage of clinical data.
Again, the device requires insufficient space. Even the Mini proton therapy system takes up a few hundred square meters, while the traditional treatment room only needs about 50 square meters. Most hospitals lack the space to build proton therapy.
Finally, there is a lack of professionals. Shi Zhanxiang, chief representative of the Beijing Representative Office of the Global Doctors Organization, believes that in China, there is a lack of professional medical staff in the field of proton therapy, and it is still unable to provide in-place treatment for domestic patients. In order to solve this problem, the Collaboration Center will open a green channel between domestic doctors and top US medical institutions, train domestic tumor proton therapy professionals, promote the construction of proton therapy disciplines, and cultivate talents and accumulate for the precision treatment of tumors in China. Clinical Experience.

Probiotics are a class of active microorganisms that are beneficial to the host by colonizing the human body and changing the composition of the flora in a certain part of the host. By regulating the immune function of the host mucosa and system or by regulating the balance of intestinal flora, promoting nutrient absorption and maintaining intestinal health, resulting in the production of single microorganisms or mixed microorganisms with well-defined composition that are beneficial to health.
