What are the symptoms of mid-to-late stage nasopharyngeal carcinoma

Many patients today are familiar with nasopharyngeal carcinoma. When treating nasopharyngeal carcinoma, patients should treat it correctly. The following small series introduces the symptoms of nasopharyngeal carcinoma in the middle and late stages.

Nasopharyngeal carcinoma is one of the tumors with a higher incidence in Guangdong, Guangxi, Hunan, Fujian and other provinces in my country. The incidence rate in men is 2 to 3 times that in women, and the age group with a higher incidence is 40 to 50 years old. Since nasopharyngeal carcinoma is mostly poorly differentiated squamous cell carcinoma, radiotherapy is the first choice, and 60 Co or linear accelerator high-energy radiotherapy is often used. The 5-year survival rate of radiotherapy is about 45%. Local recurrence and metastasis of nasopharyngeal carcinoma after radiotherapy is the main cause of death. Therefore, for some patients who have received 60 to 70 Gy of external radiation therapy and still have residual local lesions, intracavitary afterloading therapy can be used.

Eye symptoms: The vision of patients with nasopharyngeal carcinoma may be affected, and more commonly, the eyes are protruding, and the vision is impaired. Because the eyes are protruding due to nasopharyngeal carcinoma metastases to the eye socket, it is not accompanied by symptoms of cranial nerve damage. The mass can usually touch the nose and orbit. Nasopharyngeal carcinoma can invade the ethmoid sinus and rupture to the eye socket, or it can invade the intracranial cavernous sinus and invade the eye socket, first appearing symptoms of the anterior cranial nerve, and then protruding eyes.

Nasopharyngeal carcinoma can also invade the patient's brain, thus showing more symptoms. For example: Invasion of the superior orbital fissure: oculomotor nerve III--In addition to moving outward and outward, the eyeball is in a fixed state. Sliding nerve IV-obstruction of moving the eyeball outward. Trigeminal nerve V-sensory disorder of the upper eyelid, forehead, and eyeball. Abduction nerve VI-diplopia, eyeball abduction movement disorder. Invasion of the foramen ovale, foramen rotundum, and slope: Lower branch: sensory disorder in front of the ear, infratemporal, cheek, and anterior tongue.

Through the above introduction, patients can clearly understand the symptoms of middle and late stage nasopharyngeal carcinoma.
