The real advent of the era of non-invasive tumor treatment is realized along with the development of radiology and ultrasound technology. The progress of medicine, the development of linear gas pedal and ultrasound treatment technology also makes radiotherapy and ultrasound knife surgery technology also updated, and the wide application of three-dimensional conformal intensity modulation technology of radiotherapy and high-energy focused ultrasound knife technology provides a good platform for non-invasive tumor treatment. We have acquired high-precision linear gas pedal, whole-body 3D conformal intensity modulation-X-blade treatment system, high-precision CT simulation and positioning machine, radiotherapy planning system, radiofrequency ablation machine and high-intensity focused ultrasound knife to carry out tumor stereotactic radiation therapy, ultrasound focused therapy, radiofrequency ablation therapy, radiotherapy and chemotherapy particle implantation therapy. We have developed almost all new radiotherapy techniques, including dose guided adaptive radiotherapy (DGART), image guided radiotherapy (IGRT), intensity modulated radiotherapy (IMRT), three dimensional conformal radiotherapy (3DCRT), ultrasound guided precise radiotherapy for prostate cancer, multifraction total body irradiation, X-blade therapy, radiation field image verification, three dimensional brachytherapy, deep thermal therapy, and deep radiotherapy. In the past ten years, the hospital has invested nearly ten million RMB to update and improve the radiotherapy equipment, which has reached the advanced level in China. What is radiation therapy for tumor? Radiation therapy for tumors is a method of treating malignant tumors by using radiation such as alpha, beta and gamma rays produced by radioisotopes and x-rays, electrons, proton beams and other particle beams produced by various x-ray treatment machines or gas pedals. Radiation therapy for tumors (radiotherapy for short) is the treatment of cancer with radiation. Radiation therapy has been developed for more than a century. After Roentgen’s discovery of X-rays and Madame Curie’s discovery of radium, they were soon used for clinical treatment of malignant tumors respectively, and until now radiation therapy is still an important local treatment method for malignant tumors. About 70% of cancer patients need radiation therapy in the treatment of cancer, and about 40% of cancers can be cured radically with radiotherapy. The role and status of radiotherapy in tumor treatment is becoming increasingly prominent. Radiotherapy has become one of the main means of treating malignant tumors. Radiotherapy is only a few decades old, but it is developing rapidly. Due to the use of ultra-high-pressure treatment machines, improvement of auxiliary tools and accumulation of experience, the treatment effect has been significantly improved, and now it has become one of the most important tools in cancer treatment. More than 70% of cancers in China need radiation therapy, and more than 50% of cancers in the United States also need radiation therapy. Radiation therapy can be used for almost all cancer treatments, and for many cancer patients, radiation therapy is the only treatment method that must be used. Thousands of people have been cured of their cancer with radiation therapy alone or with radiation therapy, surgery, chemotherapy and biologic therapy. Doctors can use radiation therapy to crumple the tumor and make it easier to remove before the patient’s surgery, and after surgery, to inhibit the growth of remaining cancer cells. What is high-energy focused ultrasound knife technology? How does this technology cure the disease? As of 2001, there were 34 hospitals in China promoting the application of high-energy focused ultrasound knife technology. The reason why this technology is promoted is that it is called “the new technology of non-invasive treatment of tumor in the 21st century” by domestic and foreign experts, and China is in the forefront of research in this field in the world. Although ultrasound is a kind of mechanical wave, it is not radioactive and has the characteristics of energy penetration in biological tissues, and its directionality, focus and penetration are also very significant. High-energy focused ultrasonic knife is to gather the ultrasonic waves emitted outside the body to the tumor tissues in the body, through thermal effect, cavitation effect, mechanical effect, acoustic chemical effect, etc., to cause irreversible coagulative necrosis of the tumor tissues, so that the cancer tissues lose the ability of proliferation, infiltration and metastasis, and thus be dissolved and absorbed by the body to achieve the purpose of treatment. Why can high-energy focused ultrasound knife technology create a new era of tumor treatment? Is it only because of its non-invasive nature? The reason why high-energy focused ultrasound knife technology can create a new era of tumor treatment is not only because the technology can treat tumors without incision, trauma, pain and toxic side effects, but also because the technology has the following advantages that other therapies do not have: 1. Non-invasive: it only works on the tissues in the target area, and the adjacent tissues and organs are not affected. 2. No need to operate: The technology focuses multiple beams of ultrasonic waves emitted outside the human body on tumor tissues through water medium, and achieves the purpose of tumor treatment by heating the tissues, and the whole treatment process is carried out in a safe and painless manner. 3.Monitorable: During the treatment process, the treatment effect can be monitored by the change of ultrasonic shadow of tissue necrosis after treatment. 4, no pain, no toxic side effects: the treatment process without any anesthesia, no skin burns, to achieve a high degree of unity of treatment safety and effectiveness. Since high-energy focused ultrasound knife technology has such outstanding advantages, what kind of tumor patients can be applied to this therapy? The scope of application of high energy focused ultrasound knife technology for tumor treatment is very wide, but the main focus is on solid tumors, and its indications can be briefly summarized as follows: 1, pancreatic cancer, thyroid cancer, breast cancer, etc. 2.Patients with advanced cancer whose radiotherapy is ineffective: Although radiotherapy has certain efficacy in treating tumors, the efficacy is more limited. Due to the toxic side effects of chemotherapy, many patients choose to give up in the middle of treatment because they can hardly tolerate the follow-up treatment. 3.Solid tumors of various organs in the abdominal cavity and pelvis: such as rectal cancer, ovarian cancer, cervical cancer, metastatic cancer of abdominal lymph nodes, liposarcoma and other primary and recurrent tumors and superficial tumors such as thyroid, breast and limb. High-energy focused ultrasound knife technology and radiotherapy technology create a new era of non-invasive treatment of tumors.
