How to treat nasopharyngeal carcinoma

summary

Some time ago, my aunt was diagnosed with nasopharyngeal carcinoma, but the discovery was relatively timely. After all, it was early, so the treatment process was relatively smooth. Then the doctor told us that if we want to treat nasopharyngeal carcinoma now, there are many kinds of treatment methods. Now I will tell you how to treat nasopharyngeal carcinoma.

How to treat nasopharyngeal carcinoma

Treatment 1: because the primary focus of nasopharyngeal carcinoma is deep and surrounded by overlapping bone, high-energy radiation sources with strong penetration, low skin volume and low absorption, such as 60Co or high-energy x-ray of linear accelerator, should be selected. Among the two devices, accelerator is the best because it produces very small penumbra, high and even dose in deep part, and less damage to surrounding normal tissues. For the residual tumor after external irradiation, X-ray body cavity tube or afterloading cavity can be used for supplementary treatment. Now many people say radiotherapy, because radiotherapy sleep faster, the effect is better, can effectively kill cancer cells, but radiotherapy for human body damage is very big.

Treatment 2: the nasopharynx and its adjacent sinus cavity, space, skull base and neck should be included in the radiation field of each case. However, the dose should not be overlapped or omitted. In principle, all parts of the body should be irradiated at the same time, but if the patient has severe headache, epistaxis, etc., he can first use small field irradiation to alleviate the symptoms, and then use comprehensive field irradiation. If conditions permit, we can do radiotherapy, but not everyone can do radiotherapy.

Treatment 3: non main treatment, only in a few cases. The indications are as follows: nasopharyngeal localized lesions do not subside or recur after radiotherapy. Neck lymph node dissection is feasible for patients with metastatic lymph nodes in the neck, which do not subside after radiotherapy and present as an active solitary mass. Generally speaking, in clinical medicine, there are many people who choose surgical treatment. They can choose surgical treatment in the early stage, but not in the late stage.

matters needing attention

Radiotherapy is the main treatment for nasopharyngeal carcinoma, and the residual lesions can be removed surgically. The irradiation range included nasopharynx, skull base, neck and orbit. The primary dose was 65-70 Gy and the secondary dose was 50-60 Gy. The prognosis is poor because the tumor is prone to recurrence and early metastasis. The 5-year survival rate of squamous cell carcinoma is 0% - 10% in radiosensitive group and 30% in radiosensitive group. In the process of treatment, do not eat pungent heavy taste food, it is better to eat liquid food, easy to digest, or high nutritional value, such as fresh fruits and vegetables, bean products and dairy products.
