How to treat cerebral hemisphere tumors? What are the treatments for cerebral hemisphere tumors?

The clinical manifestations of tumors in different brain hemispheres are different. No matter what kind of symptoms they are, they will damage the patient's health, so active treatment is necessary. Currently, surgical treatment is the most basic way to treat this disease, followed by supplementary treatment, that is, radiotherapy and chemotherapy.

Cerebral hemisphere tumors are a very common type of brain tumor in clinical practice. Because the tumors grow in different locations, the symptoms that people experience after becoming ill are also different. For example, when the tumor compresses the frontal lobe, the patient often has a cold expression, while when it compresses the precentral gyrus of the human body, the patient will have symptoms of hemiplegia. In addition, epilepsy and increased intracranial pressure are also very common, so timely treatment is required after the onset of the disease. So, how to treat cerebral hemisphere tumors?

1. Surgical treatment of cerebral hemisphere tumors

This method is currently one of the most basic ways to treat cerebral hemisphere tumors. In clinical practice, if the site of tumor growth can be removed by surgery, then this method is given priority. Some patients have impaired consciousness or have symptoms of brain herniation, so surgical treatment can be used as an emergency measure to completely remove the tumor through surgery. However, some tumors grow deeper or have invaded the patient's neural structure, so only partial resection and decompression can be performed, such as bone craniotomy and cerebrospinal fluid shunt surgery, etc. These surgeries can be used to relieve the symptoms of increased intracranial pressure.

2. Radiation therapy for cerebral hemisphere tumors

1. Conventional radiotherapy

It is suitable for patients who are sensitive to radiation, and linear accelerators and 60CO treatment machines are mostly used for treatment.

2. Stereotactic radiosurgery

If the patient's tumor diameter is less than 3cm, stereotactic radiation can be performed, such as with the γ-knife, which is clinically effective. However, when the patient's tumor diameter is larger, the X-knife can be used, but its overall effect is not as good as that of the γ-knife.

3. Radionuclide internal radiation therapy

Patients with cystic craniopharyngeal tumors can be treated in this way, while the commonly used radionuclides for invasive pituitary tumors and other cerebral hemisphere tumors are 32P, 90Y, etc. In addition, if the patient's tumor tissue is prone to spread in the subarachnoid space, then whole brain and spinal cord irradiation is required.

3. Chemotherapy of cerebral hemispheric tumors

Chemotherapy is actually a supplementary treatment for cerebral hemisphere tumors, because it is performed on the basis of surgical resection of brain tumors. Generally speaking, the less tumor tissue there is in the patient's body after cerebral hemisphere tumor surgery, the more significant the effect of chemotherapy will be. Currently, the commonly used chemical drugs in clinical practice include nitrosoureas, methyl procarbazine, etc.
