Still need radiotherapy and chemotherapy after brain tumor surgery?  Some patients also asked why radiotherapy and chemotherapy were needed after surgery.

There are more than 100 billion nerve cells in the brain, and various blood vessels and nerves are intricate. Different functional areas overlap and are in charge of language, hearing, vision, movement, sensory and other functions.

Brain tumor is a kind of tumor that grows in the central nervous system of the brain. Its impact on the body is often very significant and even fatal. Once abnormal, it may affect the nerves and brain tissue, etc., showing various symptoms, and many patients are suffering. Unbearable.

Still need radiotherapy and chemotherapy after brain tumor surgery?

In clinical practice, if a patient is diagnosed with a brain tumor, neurosurgeons generally recommend that the patient undergo surgery to remove the tumor to prevent the tumor from growing and causing symptoms to continue to worsen.

Patients with brain tumors often ask: Do they still have to undergo radiotherapy and chemotherapy after surgery? Some patients also asked why radiotherapy and chemotherapy were needed after surgery.


So, which brain tumor patients need radiotherapy and chemotherapy?

The Export introduced: Surgical treatment is to remove all tumors as much as possible, but it cannot guarantee that all tumors can be completely removed, nor can it be guaranteed that tumors will not grow and recur. Therefore, radiotherapy and chemotherapy are for further treatment, through surgery + radiotherapy and chemotherapy. Minimize the adverse effects of tumors as much as possible. Of course, not all patients with brain tumors need radiotherapy and chemotherapy. When the patient has any of the following conditions, radiotherapy and chemotherapy are required after surgical removal of the tumor:


1. Tumor pathological diagnosis

The case diagnosis of tumor includes two contents: tumor type and tumor grade.

Brain tumor types: Different types of tumors have different symptoms and characteristics. Common types of brain tumors include glioblastoma, meningioma, pituitary tumor, craniopharyngioma, etc.

Brain tumor grade: The grade of brain tumor is the malignant degree of the tumor. It can be divided into benign brain tumor and malignant brain tumor. Benign brain tumors include meningiomas, pituitary tumors, etc.; malignant brain tumors mainly refer to gliomas, with different types Tumor grades are different, but whether it is benign brain tumor or malignant brain tumor, the lower the grade, the better the prognosis of the patient.

Generally speaking, low-grade tumors and benign tumors have a clear boundary with brain tissue. Most of them can be completely removed without radiotherapy and chemotherapy. However, high-grade tumors and malignant brain tumors have unclear boundaries with brain tissue and surgery is often It is difficult to completely remove, so radiotherapy and chemotherapy are needed to control tumor growth.

2. Whether the tumor is completely cut

Secondly, the degree of surgical resection should also be considered. Generally speaking, if the tumor can be completely removed during surgery, it is not necessary to do radiotherapy and chemotherapy most of the time after surgery. However, if it is a malignant tumor, such as glioma, the surgery is difficult to complete and must be removed after surgery. The tumor is further treated with radiotherapy and chemotherapy.

3. The location of tumor growth

If the tumor grows in an important functional area of ​​the brain, when resecting the brain tumor, not only the problem of resection of the tumor must be considered, but also the functional area of ​​the brain tissue must be protected from being affected, which will affect the tumor resection plan. Generally, subtotal resection is performed. After the corresponding radiotherapy and chemotherapy.

4. The patient’s physical condition

If the patient needs radiotherapy and chemotherapy, then the patient’s physical condition must be able to support the corresponding treatment. If the patient’s physical condition is not good, then radiotherapy and chemotherapy are not allowed.


In general, whether patients with brain tumors need radiotherapy and chemotherapy, the most important factor is whether the surgery has completely removed the tumor. If a complete tumor resection is done, radiotherapy and chemotherapy are not required most of the time, but if it is not completely removed, most Radiotherapy and chemotherapy are needed for further treatment, unless the patient’s body cannot tolerate radiotherapy and chemotherapy.
