The prognosis of patients with sacrococcygeal teratoma is related to the nature of the tumor, the patient’s age, and the effect of treatment, etc. Generally, patients with benign sacrococcygeal teratoma and complete surgical resection have a better prognosis. The prognosis of patients with malignant sacrococcygeal teratomas that have metastasized and cannot be removed by radical surgery is poorer. Sacrococcygeal teratoma belongs to a kind of tumor with unclear etiology, 90% of sacrococcygeal teratomas are benign tumors, mostly seen in newborns or infants, generally benign teratomas are given surgical treatment, most of them can be cured, with a relatively low recurrence rate, and the five-year survival rate of the patients reaches about 95%, with a good prognosis. Very few sacrococcygeal teratomas are malignant, if the tumor has already metastasized when found, it can not be cured by surgical resection of the tumor, but also need to take radiotherapy, chemotherapy and other means of treatment, this kind of patients have a shorter survival period, the prognosis is worse. If the patient found sacrococcygeal teratoma, it is recommended to go to a regular hospital to avoid delaying the condition.
