The most important medical treatment for nasopharyngeal carcinoma

Among cancer diseases, nasopharyngeal carcinoma is also very easy to be caused. Genetic or infectious factors can easily cause the occurrence of nasopharyngeal carcinoma. So, what is the most important medical treatment for nasopharyngeal carcinoma ? Next, let's learn about it from the following article.

1. Conventional external irradiation is one of the treatment methods for nasopharyngeal carcinoma. It mainly uses high-energy rays, such as gamma rays generated by cobalt therapy machines or high-energy x-rays generated by medical linear accelerators. For neck irradiation, low-penetration radiation, i.e. electron rays, can be used. The irradiation field is designed with reference to clinical examinations, imaging materials, pathological types, etc. The first-stage tumor dose in the irradiation field is 3.5 to 4 weeks, reaching 36 to 40 grays (gy). In the second stage, the treatment of nasopharyngeal carcinoma is adjusted according to the degree of tumor regression. For radical radiotherapy of nasopharyngeal carcinoma, the irradiation dose of the skull base and nasopharynx is about 6 to 8 weeks. If there is no cervical lymph node metastasis, a preventive dose of 45 to 50 grays is sufficient for the neck.

2. Intranasopharyngeal afterloading radiotherapy, the computer-controlled motor correctly delivers the radiation source to the irradiated area, and the treatment planning system makes an individualized plan design, which has a positive effect. At present, for early-stage nasopharyngeal carcinoma, after a certain dose of conventional external irradiation, high-dose rate brachytherapy can be used to supplement intranasopharyngeal afterloading therapy, or when there are relatively limited residual or recurrent lesions in the nasopharyngeal wall after radical external irradiation, high-dose rate brachytherapy can be used to supplement intranasopharyngeal afterloading therapy. This treatment of nasopharyngeal carcinoma can achieve better results.

The above is a detailed description of the treatment of nasopharyngeal carcinoma. I hope it can help everyone understand the knowledge of nasopharyngeal carcinoma in this regard and cure nasopharyngeal carcinoma in time.
