Gliomas that are not cleanly removed by surgery may require postoperative adjuvant radiation therapy, chemotherapy, and re-surgery if necessary. Gliomas are usually epithelial tumors of the central nervous system, and the vast majority of them are malignant tumors with an invasive growth pattern, which makes surgical resection difficult, and is often not possible due to the fact that the tumors are adjacent to important blood vessels as well as vital areas such as important neurological function areas or vital centers. The residual tumor may wait until the surgical pathology results are returned to clarify its pathological type, and then be treated with radiation therapy (general radiation therapy or gamma knife radiation therapy, etc.), chemotherapy (oral temozolomide capsules, etc.), and electric field therapy, as appropriate. If these treatments are not effective in controlling the residual tumor growth conditions, another surgical treatment can also be performed under permissible conditions, trying to maximize the extent of resection. Gliomas that are not cleanly removed by surgery require follow-up treatment under the guidance of a neurosurgical specialist and regular follow-up.
