How to treat brainstem tumors depends firstly on which part of the brainstem the tumor grows in, the size of the tumor, the specific pathological condition and the general condition of the patient. Surgery is usually recommended, but the risk of surgery is very high, and the requirements for hospitals and doctors are very high, which are difficult for general hospitals to meet. If the patient’s risk of surgery is very high, radiotherapy can be recommended. Although the damage of radiotherapy is small, it cannot achieve the goal of complete surgical resection, and even if surgery is done to resect the disease, according to the pathological condition after surgery, some of them need supplementary radiotherapy. As for chemotherapy, because it is difficult for chemotherapeutic drugs to enter the cerebrospinal fluid, it has little therapeutic effect in brainstem tumors. There are no good drugs for targeted therapy either.
