Early and middle stage of submandibular gland cystic carcinoma has higher survival rate, and the survival rate within 5 years can reach 70%~80%, while the survival rate of late stage is lower. Early and middle stage submandibular cystic carcinoma can be controlled through timely treatment and the probability of metastatic spread of cancer cells is low, so the survival rate of this kind of patients is relatively high, and the 5-year survival rate of most of the patients can reach 70%~80%. In case of advanced submandibular cystic carcinoma, the best time for surgery has been missed, and only radiotherapy and other methods can be chosen to slow down the progression of the disease, and this kind of patients can not achieve clinical cure, and the survival rate will also be significantly reduced. If the diagnosis of submandibular cystic carcinoma is confirmed, it is recommended to consult the doctor in time and actively treat the disease, which can help patients prolong the survival time and improve the quality of life.
