Head and neck tumor radiotherapy prospect.

The !-----POST ASCO Head and Neck Tumor Special Session was held in Chengdu.the big curry gathering, academic content is wonderful, deeply explore the development of head and neck tumors.in recent years, the treatment of head and neck tumors has made rapid progress, and surgical treatment, chemotherapy, chemotherapy, immunotherapy and so on have made great progress, which has effectively promoted the progress of precision treatment.had the honor of inviting Professor Yan Jinyi to Sichuan Cancer Hospital, affiliated with the University of Electronic Science and Technology School of Medicine, to explain the present situation and prospects of radiotherapy in detail.Yu Jinyi, Director physician/professor/doctoral tutor, Director of Sichuan Cancer Prevention and Control Center, Director of The Key Laboratory of Radiology, Sichuan Province Key Laboratory, 8th Chairman of the Chinese Medical Association's Radiocancer Treatment Credit Association, Chairman of the Nasopharyngeal Cancer Committee of the Chinese Association of Cancer, China Anti-Cancer Association Radio-Oncology Deputy Chairman of the Special Committee, advanced workers of the National Health and Family Planning System, young and middle-aged experts who make outstanding contributions to the National Health And Family Planning, experts from the State Council who enjoy special government subsidies, outstanding scientific and technological workers from all over the country, experts from the Tianfu People's Program in Sichuan Province, winners of the Sichuan Outstanding Talent Award, and chairman of the Oncology and Radio-Oncology Committee of Sichuan Medical Association.head and neck tumor radiotherapy status for head and neck tumors, surgery can easily cause functional or disfigurement damage.and radiation therapy (radiotherapy) as a minimally invasive physical means, from the beginning of the birth to the present more than 100 years, has been an important treatment for head and neck tumors.to the 21st century, thanks to the development of physical technology and computer technology, the accuracy of modern radiotherapy has become more and more clear, which further consolidates the important position of radiotherapy in the treatment of head and neck tumors.although the era of comprehensive therapy has come, but in the field of head and neck tumors, radiotherapy status is still irreplaceable. first ofall, taking nasopharyngeal cancer as an example, the mainstream treatment of nasopharyngeal cancer is not radiation therapy., other types of head and neck tumors such as tongue tumors, nasal tumors and some complex anatomical structure, surgery into the trauma of large cranial tumors, radiation therapy also plays a very clear role.therefore, the attack on the "enemy's fortress" also depends on radiotherapy.in short, radiation therapy is still in the mainstream in the treatment of head and neck tumors.head and neck tumor precision radiotherapy trends, radiotherapy precision treatment is like a satellite-directed cruise missile precision strike, and the surgery is like a deep enemy combat of the Marine Corps, its own damage and damage is inevitable.as a modern technology, precision therapy enables precise positioning of treatment objectives and minimization of damage to the body.philosophy and physics are the foundation of all science in the world, as is radiotherapy.radiotherapy is based on the principles of physics, based on the combination of medicine and informatics, medicine and science and engineering - "medical and credit" cross-platform treatment. therefore, it is not difficult to foresee the future development of radiotherapy with the help of artificial intelligence development of the east wind. , like the image navigation system used in the current surgery, will make the surgical field more clear, and in the future image navigation will develop into a guided approach based on molecular image, functional image, genomics and molecular biology, and develop into a true imaging molecular hiscombe to guide radiotherapy. , in future tumor radiotherapy, even a 3 cm tumor may distinguish in the form of calculus which part of the tumor cell is active, which part of the tumor cell is inactive, and then according to this formation of an uneven radiation dose of the blow, to obtain a suitable tumor elimination. is currently in clinical application of the Cyber knife (shot knife) is also based on artificial intelligence to guide the implementation of precision treatment. therefore, the development of radiotherapy can be summed up in two sentences: (1) more and more precise, and (2) complement each other with surgery to form more new programs that allow patients to receive better treatment. the future and potential of radiotherapy combination immunotherapy Before the advent of immunotherapy, the concept of immunology came from human immunity. the body's immune system is a huge immune regulatory system, including the nervous system, respiratory system, digestive system and other regulation. it is generally accepted that tumors occur due to genetic mutations in normal cells, which are determined by external and genetic factors. normal cell mutation, the immune system loses its regulatory effect on it. and the advent of immunotherapy has changed that. , like the concept of "other diseases and cures" in Chinese medicine, the connotation of immunotherapy is similar, that is, when different cancer species have the same immune pathway mutation, an immunotherapy plan can be developed for this pathway. individuals, immunotherapy is much less harmful to the human body than other cell drug therapy. therefore, if surgery, radiotherapy and immunotherapy are properly combined in head and neck tumor therapy, it can cause less pain while the patient gains long-term survival benefits, which also sustains the concept of "patient-centered" human treatment. and head and neck anatomy and function may vary in molecular distype when it mutates. therefore, immunotherapy combination surgery and radiotherapy, in the head and neck tumor treatment has great potential. but head and neck tumors are not high-incidence tumors, so they must have a difficult way to go in basic research and conversion research.
