Postoperative radiotherapy for gliomas is related to the grade of the tumor, not to the presence of hemiparesis. In the case of grade I gliomas, postoperative radiotherapy is usually not administered. If a patient with a grade II glioma, grade III glioma, or grade IV glioma undergoes surgery, postoperative radiotherapy treatment is usually required. Glioma surgery may result in hemiparesis, aphasia, and cognitive deficits after surgery because a portion of the brain tissue needs to be removed. However, these do not affect subsequent treatment options. Whether or not radiotherapy is possible after glioma surgery needs to be judged according to the grade of the glioma. If the patient presents with grade I glioma, this type of glioma has a low degree of malignancy, and can usually be completely removed by surgery, and usually does not require radiotherapy or chemotherapy treatment after surgery. If the patient presents with grade II glioma, grade III glioma, or grade IV glioma, these tumors may show infiltrative growth, and even with surgical treatment for glioma, the glioma cannot be completely removed. At this point, the patient will need to be treated with radiotherapy or chemotherapy after surgery, which will help to fully kill the cancer cells. Glioma patients will have pathology results after surgery, and doctors will judge whether to treat with radiotherapy or radiation therapy according to the patient’s condition. It is recommended that glioma patients should ensure enough rest after surgery and go to the hospital for regular checkups.
