Symptoms of malignant nasopharyngeal carcinoma

summary

Radiotherapy is the first choice for nasopharyngeal carcinoma. However, surgical resection and chemotherapy are also indispensable for patients with well differentiated carcinoma, late course of disease and recurrence after radiotherapy. Symptoms of malignant nasopharyngeal carcinoma? Next, I'd like to share my views with you.

Symptoms of malignant nasopharyngeal carcinoma

If the focus of epistaxis and epistaxis is located in the posterior wall of the top of the nasopharynx, it can cause epistaxis in light cases (blood in the sputum) and epistaxis in severe cases. This symptom is common in patients with ulcers or cauliflower type on the surface of tumor, but rarely in submucosal type.

Ear symptoms tumor in the pharyngeal recess or eustachian tube round occipital area, due to tumor infiltration, compression eustachian tube pharyngeal mouth, appear the symptoms and signs of secretory otitis media: tinnitus, hearing loss, etc. in clinic, many patients with nasopharyngeal carcinoma are found because of ear symptoms.

The trigeminal nerve, abducens nerve, glossopharyngeal nerve and hypoglossal nerve were more involved in the process of peripheral infiltration of nasopharyngeal carcinoma, while olfactory nerve, facial nerve and auditory nerve were less involved. Headache is a common symptom. Clinically, most of the patients presented with unilateral persistent pain, mostly in the temporal and parietal regions.

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.
