Glioblastoma is the most common form of malignant tumor inside the skull, and the vast majority of glioblastomas are highly malignant. Once changes in this condition are detected, generally, the patient doesn't have much time left. If it is a relatively better glioblastoma, which means it is highly differentiated, the survival time is about 1-2 years. For some poorer glioblastomas, or those with low differentiation, their survival period is often only about six months, and they continuously spread along with nerve fibers to the surrounding areas. They might even metastasize to distant places through cerebrospinal fluid, blood, lymph, and other means. Therefore, even if surgery is used to remove a single lesion, other parts of the body may still demonstrate metastatic lesions. Hence, the treatment approach for this is comprehensive.
