The onset age of laryngeal cancer patients is mostly between 50 and 70 years old, and the incidence rate of males is significantly higher than that of females. Laryngeal cancer is the second most common respiratory cancer after lung cancer, and ranks among the top three in head and neck cancers.
The lesions of many laryngeal cancer patients develop step by step. Come, some elderly people often have sore throat, hoarse voice, foreign body sensation in the throat, etc., but they often mistake it for a cold or chronic pharyngitis. Don’t take it seriously, thus delaying the formal diagnosis and treatment.
Now there are many tumor treatment methods and drugs, which are important The key is to choose a regular and reliable professional hospital and scientific and reasonable treatment methods. Minimally invasive interventional therapy is especially suitable for patients who have lost the opportunity for surgery in the middle and late stages and are intolerant of radiotherapy and chemotherapy. For laryngeal cancer patients who are not suitable for surgery or who have lost the opportunity for surgery, radioactive seed implantation technology can obtain satisfactory curative effects on the basis of preserving physiological functions and quality of life.
Radioactive seed implantation is a part of the comprehensive treatment of malignant tumors. It is an effective technique and belongs to a kind of brachytherapy. In this method, the radioactive iodine 125 seeds are implanted into the tumor or the tissue possibly invaded by the tumor by a minimally invasive (percutaneous puncture) method or surgery, and can also be implanted into the lymph node of the tumor metastasis. During the decay process of radioactive seed implantation, a low dose of gamma rays is emitted to continuously irradiate the tumor tissue, which can kill the fissioned tumor cells and the hypoxic cells around the tumor in different periods, so it can effectively treat tumors and prevent tumors. recurrence and metastasis.
Through the precise planning of the particle implant planning system, accurate Design the location, quantity and delivery route of implanted particles. Radioactive seed implants work in conjunction with other treatments to make other treatments more effective. Implantation of radioactive seeds only takes effect inside the implanted tumor, and does not have a major impact on the surrounding normal tissues. The particles are packaged in a titanium alloy shell, which has good tissue compatibility with the human body, and will not produce radiation leakage and pollution.
