In the eyes of many experienced doctors, patients with nasopharyngeal cancer radiotherapy have a “face” that cannot be removed. Radiotherapy for nasopharyngeal cancer has been internationally recognized as a standard treatment method, which is jointly determined by the incidence site of nasopharyngeal cancer, characteristics of the tumor and characteristics of the treatment method. What kind of helplessness is there under the face of radiotherapy for nasopharyngeal cancer? Nasopharynx is located between the base of the skull and the soft palate, connecting the nasal cavity and oropharynx, which is the key channel for breathing. It is a key channel for respiration. It is connected to the skull base, with many pairs of cerebral nerves passing from back to front; it is connected to the cervical vertebrae and pharyngeal retractor muscles, pharyngeal fascia, etc., and there are many neighboring important organs in the periphery. In addition, the nasopharyngeal lymphatic network is extremely rich, and the lesion is prone to cervical lymph node metastasis. In view of such a complex anatomical structure, it is difficult to provide good surgical conditions in nasopharyngeal area; moreover, most of nasopharyngeal cancers are low-differentiated cancers, which are more sensitive to radiation, so the first choice of nasopharyngeal cancer treatment is radiotherapy. However, after traditional radiotherapy, the quality of life of nasopharyngeal cancer survivors is not as good as before. Dry mouth, slurred speech, tasteless food, stiff neck ……, stiff facial muscles like a mute face mask lingering on the face of the survivors. This is a result of peripheral damage caused by the inability of the traditional radiotherapy era technology to achieve precise adaptation to the shape of the tumor. Different times bring different destinies A patient who recently came for review and suffered from nasopharyngeal cancer 15 years ago, as a veteran soldier, the pain of the traditional radiotherapy process had caused the robust man to rapidly lose nearly 30 pounds. His treatment was quite successful under the technical conditions at that time, but the glass of water that followed him and his slurred speech revealed how much normal fun he had lost in his life over the years. Another architect who was treated in our hospital 2 years ago, due to the long-term work of drawing and drafting, his physical quality is not too good, but fortunately at that time, our hospital treatment used the world’s most advanced modern precision radiotherapy TOMO treatment system. During the month of treatment, he was not even hospitalized, and the daily 10-minute irradiation hardly brought him any discomfort. It has been more than 2 years since he recovered and he has hardly experienced any radiation side effects. Due to the precise shape of the radiation therapy, the side effects on the surrounding tissues were avoided, and he returned to work in about half a year, just like a normal person. Precision radiotherapy says goodbye to side effects The nasopharyngeal area is deep and the target area is usually large and irregular, so it is difficult for traditional radiotherapy techniques to match the shape of the high-dose area with the target area, which will easily cause damage to the surrounding organs. The birth of modern precision radiotherapy precisely combines image guidance, high-dose focusing and precise shaping with high efficiency, which can produce customized shaped dose distribution even for adjacent tissues and organs of 1-2cm, and minimize the possible side-effects of radiotherapy, which not only provides a strong fight against tumors, but also guarantees the quality of patients’ post-surgical survival. It is also known as the treatment method with the highest cost-effectiveness ratio. According to the survey of World Health Organization, 80% of nasopharyngeal cancers in the world occur in China, and nasopharyngeal cancer is also known as Chinese cancer, so the precise radiotherapy technology is undoubtedly a blessing for nasopharyngeal cancer patients and guarantees their long-term and high-quality survival.
