Technical Field
The invention relates to the technical field of medical instruments, in particular to a turnover type neck tumor radiotherapy device.
Background
Radiation therapy is one of the main means of cancer therapy, and unlike surgery, radiation therapy is the use of radiation to kill cancer cells, and the appearance and function of normal tissues and organs may often be preserved, so radiation therapy is also called as a non-knife cancer resection. For example, in early stage vocal cord cancer, the radiation therapy can cure the cancer, and the patient can be relieved from laryngectomy, thereby keeping the vocal function of the patient.
Neck treatment is an integral part of head and neck cancer treatment, and it means that No patients with No or marked enlarged lymph nodes should be included, not only when there is a definite cervical metastasis. After pathological examination of selective cervical cleaning specimens in No cases of head and neck cancer, 16-66% of lymph node sublineal cancer metastases vary according to the primary cancer. No case only treated with primary focal radical therapy, one third of the cases were transferred from the neck, and the treatment effect was poor. If the disease is treated by routine selective cervical cleaning or preventive cervical radiotherapy, the recurrence rate is obviously reduced. For example, the research of the university of Virginia in America discovers that the neck control rate of the No case of tongue cancer is 38% when the neck is not treated or is limited after primary focus radical treatment, and the neck control rate is as high as 95% by adopting full-neck preventive radiotherapy or radiotherapy and neck cleaning operation. For the head and neck cancer cases with cervical lymph metastasis, neck treatment is more indispensable, and the value is self-evident.
