Brain tumor grade 4 generally refers to glioblastoma, a highly malignant intracranial tumor, which has a poor prognosis. The survival rate of glioblastoma is related to many factors, such as the patient’s physical condition, the rate of disease progression, and psychological state, and varies from person to person; there is no absolute survival rate.
The latest evidence from large-scale clinical trials shows that the overall median survival of glioblastoma patients, after surgery, radiotherapy, temozolomide chemotherapy and electric field treatment, has reached 20.9 months; the 1-year survival rate is 73%, the 2-year survival rate is 43%, and the 3-year survival rate is 26%, and the specifics need to take into account the patient’s physical factors, the progression of the disease, and the combination of treatments and other factors at the same time.
Glioblastoma is usually resected by craniotomy and adjuvant radiotherapy and chemotherapy. If the tumor is infiltrative and has no obvious boundary with the surrounding brain tissues, it is very difficult to completely remove the tumor through surgery. Even after resection, the tumor may recur and require surgery again.
After diagnosed with glioblastoma, patients should follow the doctor’s instructions to standardize the treatment, as well as maintain a healthy lifestyle, optimism, etc., which can help to improve the quality of life.
