Survival time after surgery for primitive neuroectodermal tumors is usually 3 to 5 years, but some patients have a longer survival period, which may exceed 5 years, but most of them do not survive for a long time. Primitive neuroectodermal tumor is a kind of tumor originated from primitive nerve body, which belongs to rare and highly malignant tumors with poor prognosis, and tends to grow and metastasize invasively through the cerebrospinal fluid, with rapid progression of the disease, and the survival period can be prolonged if timely surgical treatment is taken and combined with radiotherapy after surgery. Once the diagnosis of primitive neuroectodermal tumor is confirmed, it is necessary to actively cooperate with the doctor to take surgical treatment, pay attention to regular review after surgery, and cooperate with the doctor to take follow-up rehabilitation treatment.
