It's like brainwashing to get rid of a brain tumor
It's scary
But it's effective
Modern tumor treatment emphasizes targeted therapy, personalized therapy, and integrated therapy, which have become the three principles of tumor treatment, and more and more experts in the field are making such an appeal at numerous tumor high-level forum seminars. . At present, the methods used for tumor treatment can be basically summarized as surgery, radiotherapy and chemotherapy, which are complementary and compatible with each other. However, 70% of tumor patients, regardless of surgery or not, have to take radiotherapy, and it can be predicted that in the next few decades, radiation therapy will still be one of the most important methods of treating tumors. At present, proton therapy has been developed on the basis of radiotherapy and is the most effective method of radiotherapy.
Proton therapy can be applied to children's tumors as well as tumors of brain, pelvis, head and neck, chest and abdomen, skull base, etc. It is a new technology to treat tumors by using the unique "Bollinger peak" of proton wire, and it has the advantages of penetrating into the tumor and penetrating the tumor, due to the real implementation of the "three-dimensional directional fixed-point blast". As it can truly implement "stereotactic targeted blasting", it is characterized by strong penetration performance, good dose distribution, high local dose and low side scattering. Compared with traditional radiotherapy, proton therapy has at least four advantages:
First, proton therapy helps to improve the level of tumor irradiation. The proton beam used for treatment needs to be finely modified according to the patient's lesion so that it meets the needs of the treatment to achieve the optimal dose distribution.
Second, proton therapy helps to improve the local control rate. As long as the largest peak portion is aimed at the tumor during proton therapy, the tumor can receive the maximum dose, while the normal cells in front of the tumor only receive about 1/3 of the maximum dose, and the normal cells behind the tumor are also basically unharmed, which avoids the possibility of therapeutic failure due to the insufficient local dose, improves the local control rate of the lesion area, and prolongs the patient's survival period, while still enjoying and the normal people.
Thirdly, proton therapy helps reduce complications. When ordinary radiation kills cancer cells, it can't distinguish between "good and bad" cells, and can "accidentally" injure normal tissues around the cancer cells. Especially the heart, blood vessels, nerves and other important organs are more sensitive to radiation. Once radioactive damage is caused, not only is it difficult to recover, but it will also cause serious complications. In contrast, proton therapy can successfully minimize the occurrence of post-treatment complications because it basically does not come into "close contact" with normal cells. At the same time, according to many domestic and foreign literature, it can also greatly reduce the risk of patients developing a second tumor.
Fourth, proton therapy helps to enhance the effects of radiotherapy and chemotherapy. In combination with conventional radiotherapy techniques, proton therapy also improves survival time while reducing radiation damage.
In the United States, 10,000 people receive proton therapy each year. In order to promote proton therapy technology, an international treatment center has been and many countries around the world cancer treatment institutions for in-depth cooperation. At present, in China's Shandong Zibo Wanjie Cancer Hospital put into operation in the world's fourth medical proton therapy system of proton center has also become a member of the International Proton Committee, with this treatment center has formed a collaborative relationship. "It is our responsibility to make proton therapy benefit cancer patients all over the world." said a leading proton therapy chief physician.
