How is brain cancer treated surgically

In recent years, brain cancer has gradually risen again, and brain cancer screening has been elevated to a position that needs attention. Humans are afraid of death, but when it is really irreversible, they are powerless. There are countless people who have died from cancer, and brain cancer is one of the killers. People who are usually very careful and cautious will find symptoms in the early stage, but some people do not have any symptoms in the early stage, so it is best to check regularly. Clinically, it is found that most brain cancer patients have reached the middle and late stages when they show obvious symptoms. Here, we remind the majority of friends who are related to brain cancer to pay attention.

Surgery

For primary tumors, surgical resection is performed to remove tumor cells as completely as possible and avoid

Resection of brain tumors is still the most common treatment mode. In surgical resection, studies have shown that the use of 5-aminolevulinic acid (5-ALA) to mark cancer cells and make them fluorescent can help improve the tumor resection rate. The product Gliolan (medac GmbH) has been approved for marketing in Europe. For some deeper tumors or tumors that cannot be removed by traditional surgery, stereotactic radiosurgery (Gamma knife, Cyberknife or Novalis Txradiosurgery) is also another surgical option.

For benign tumors, the chance of complete surgical removal is higher, and the patient's survival rate is also higher. For example, cerebral or cerebellar astrocytoma, sella craniopharyngioma, ventricular choroid plexus tumor, etc., no radiation or chemotherapy is required, and the recurrence rate is low, but regular CT or MRI reexamination is required. Residual benign tumors that cannot be completely removed by surgery can be observed and tracked, or chemotherapy or radiation therapy can be used immediately.

For common malignant brain tumors, such as degenerative astrocytoma, medulloblastoma, ependymoma, teratoma, etc., those that can be completely or nearly completely removed have a better prognosis, but radiotherapy and/or chemotherapy must be added to achieve the goal of controlling tumor growth.

The survival rate of patients with primary brain tumors is significantly related to the type of tumor and the patient's age and physiological function, which will affect the patient's choice of treatment mode.

The above is a brief introduction to brain cancer. For people who are related to the pathogenic factors of brain cancer, it is recommended to take preventive measures for brain cancer and receive specific treatment according to the doctor's instructions. I hope that patients can recover soon! If you have other questions about brain cancer, please consult our experts online or call for consultation.
