The prognosis of palatoglossal arch carcinoma needs to be judged in the light of the actual situation of the patient. Early stage patients have a good prognosis, with a 5-year survival rate of more than 70%. The prognosis of advanced stage patients is poorer, and the 5-year survival rate of patients is only 30%. Early symptoms of palatoglossal arch cancer are relatively mild and easy to be ignored. Common symptoms are pharyngeal discomfort, foreign body sensation, tumor enlargement, or pharyngeal pain after rupture or infection, which is aggravated when eating, or pain in the ear due to glossopharyngeal nerve reflex. In case of early stage of the disease, the tumor is small and there is no local lymphatic metastasis or distant metastasis. After the patient is actively treated and the cancerous tissue is removed through surgery, the prognosis is good and the 5-year survival rate of the patient is about 70% or more. When the tumor involves bone, muscle, skin, sinus, neck or lymph node metastasis >6cm, or there is distal metastasis, these three cases are stage IV lesions, i.e., advanced stage. The 5-year survival rate of patients is only 30%. Most of palatoglossal arch cancers are malignant tumors, however, the symptoms are not obvious in early stage, and the prognosis will be worse after the spread of cancer cells if not treated in time, so the patients should consult the doctor for examination and treatment as soon as possible if they feel unwell.
