What is Metastatic Brain Cancer?
Metastatic brain tumors are those with malignant tumors from other parts of the body that have metastasized into the skull. Carcinomas, sarcomas and melanomas can all metastasize to the skull. Most of the intracranial metastases seen in clinics are metastatic tumors, accounting for more than 90%.
Metastatic brain tumor
Definition of metastatic brain tumor disease
- Metastatic brain tumors are those with malignant tumors from other parts of the body that have metastasized into the skull. Carcinomas, sarcomas and melanomas can all metastasize to the skull. Most of the intracranial metastases seen in clinics are metastatic tumors, accounting for more than 90%.
Metastatic brain tumor disease symptoms
- Due to the rapid growth of the tumor and the severe reaction of the brain tissue, the treatment course is generally quite short. If the tumor has bleeding, the symptoms progress rapidly. If there is intratumoral necrosis, a cyst is formed, the symptoms develop faster, the symptoms of multiple tumors are heavier, and the disease course is shorter. 70% to 90% of the disease course is within half a year, rarely more than 1 year, and some can reach 2 to 3 years. The average is 3.5 to April. Symptoms mainly include increased intracranial pressure and general and local symptoms.
- 1. Increased intracranial pressure and general symptoms: Due to rapid tumor growth and severe peripheral brain edema, symptoms of increased intracranial pressure appear earlier and significantly. About 90% of patients have headache, about 70% have nausea and vomiting, more than 70% have papillary edema, 30% to 40% have fundus hemorrhage, about 20% of those with vision loss, and about 15% have abductor nerve palsy. About 15% of patients in the late stage have varying degrees of conscious disturbance and may have symptoms of cerebral hernia.
- Patients are generally in poor condition, and some are obviously thin. About 20% of patients have seizures, and most are localized. Because the tumor often affects the frontotemporal lobe and the range of cerebral edema is wide, there are often psychiatric symptoms. Common manifestations are unresponsiveness and indifferent expressions. Meningeal metastases are mainly manifested by increased intracranial pressure and meningeal irritation, and local signs are rare.
- 2. Local Symptoms: Because tumors cause severe damage to the brain, and are often multiple, local symptoms are more pronounced and involve a wider range. Corresponding signs are generated according to the location of the tumor. More than 40% of patients have hemiplegia, about 15% have hemiplegia, about 10% have aphasia, and about 5% have hemi-blindness. Those in the cerebellum have nystagmus, ataxia, etc., and may also have posterior cranial nerve symptoms.
Pathology of metastatic brain tumor disease
- There are three ways for the malignant tumor to metastasize into the skull: menstrual blood flow, lymphatic, and direct invasion, among which menstrual blood flow is the most common route.
- The metastatic pathway and site are related to the site of the primary tumor. Such as lung cancer, breast cancer, skin cancer and other metastasis through the bloodstream, multiple metastatic cancers are easily formed in the brain. Gastrointestinal cancers are more likely to metastasize through the lymphatic system and spread to the meninges.
Metastatic brain tumor prone population
- There are more males than females, with a male to female ratio of about 1.5: 1, most seen between the ages of 40 and 50.
Metastatic brain tumor complications
- 50% to 70% of patients die within six months after surgery. Only 15% survive more than one year, and individual individuals can survive more than 10 years. However, patients who have undergone surgery have a longer survival period than those who have not undergone surgery. Therefore, for most patients who are suitable for surgery, surgical treatment still has some value, and a positive attitude should be adopted.
Differential diagnosis of metastatic brain tumor
- The patient is over 40 years old, the disease develops faster, the disease course is shorter, the symptoms of increased intracranial pressure are obvious, and the symptoms are more severe and the general condition is poor. The disease should be considered first. Since brain metastases are more common from the lungs, lung images should be taken. If a lung tumor is found, or if there is a history of malignant tumors elsewhere, the diagnosis can generally be established. Further diagnosis requires special examination. CT scan has the highest diagnostic value for qualitative localization and multiple tumors.

Metastatic brain tumor examination
- 1. Blood tests: Half of the patients had accelerated erythrocyte sedimentation, peripheral white blood cells often increased, and red blood cells and hemoglobin decreased.
- 2. Skull plain film: most manifestations of increased intracranial pressure signs, individual visible pineal calcification shift.
- 3 CT scan: can locate and display changes in tumor size, shape, brain tissue, and ventricle. It is particularly easy to find multiple tumors, tumors with round or irregular shapes, and high density or mixed density images. Often mixed density is If there is necrotic cyst in the tumor, it shows a low density area. After enhancement, most of them have obvious block or ring image enhancement, and there are often low-density brain edema around the tumor. Compression and deformation of the ventricle can be seen, and cerebellar tumors can be symmetrically enlarged above the third ventricle.
Laboratory diagnosis of metastatic brain tumor
- Blood tests: Half of the patients had accelerated erythrocyte sedimentation, peripheral white blood cells often increased, and red blood cells and hemoglobin decreased.
Image diagnosis of metastatic brain tumor
- Skull plain film: most manifestations of increased intracranial pressure signs, individual visible pineal calcification shift.
Drugs for the treatment of metastatic brain tumors
- Carmine mustard; cyclohexyl nitrosourea, etc.
Preventive care of metastatic brain tumor
Prevention of metastatic brain tumor
- Have a regular life and be savvy. Don't stay up late and don't eat irregular meals a day. In this way, the circadian body clock can operate regularly, and at the same time, nerve and body fluid regulation can be organized. This is the key to preventing disease.
Metastatic brain tumor care
- Don't drink strong tea or coffee before going to bed at night, take active physical exercises, and have a balanced diet.
Precautions for metastatic brain tumor brain tumor
- When a patient has an outbreak, family members or others should place the patient on a soft mattress with one side of the bed against the wall and the other side protected by a wooden frame to avoid falls. Unfasten the neckline in time, loosen the trouser belt, and roll a handkerchief between the upper and lower teeth in the patient's mouth with bamboo chopsticks or toothbrush handles; the patient's dentures should be removed, with the head tilted to one side, and the secretions and vomit should be discharged. If epileptic seizures persist, seek immediate medical attention.
Metastatic brain tumor diet conditioning
- One: Boiled eggs in walnut shells.
- Take a few walnut shells and a few eggs, cook them in the pot for 12 hours, remove them and set aside, and heat and eat 3 pieces every day. Another: If you can find the roots and bark of the walnut tree, you can add bones with the walnut shell. It is suitable for broth. When cooking, you can sew a bag with air-permeable gauze, place the accessories in the pot, Remove excipients and discard them.
- How to use: Eat meat and drink soup with a little fried salt.
- 2: Stewed old duck with konjac.
- Due to different names in different places, it is recommended to inquire about it: this plant cannot be eaten directly, and the mouth feels numb and prickly. When cooking, apply a breathable gauze bag, and place the konjac in it. The mouth of the bag is sewn tightly with a needle thread to prevent residue from leaking out. The stew should be over 12 hours or it may be poisoned. Remove the gauze bag from the pan and discard.
- The duck used for the stew should be more than 5 years old. The older the duck, the better the effect. How to eat: Add a little salt, eat duck meat, and drink soup.
- Three: Feitian yarrow stew to kill meat.
- The so-called killing meat is a piece of meat (called different names in different places) cut by a knife stabbing into the neck of a pig when killing a pig. You can contact the butcher in advance. The flying grass is a common name and is said to be poisonous.
- Cooking method: Take 1500 grams of water, one piece of killer meat, three sections of flying yarrow, each cut is an inch long, not too long, and a large amount of the entrance will feel numb, and cook with the killer meat for 3 hours in a pot Don't put any seasonings, make tea a hot drink every day, and one soup should be consumed in one day.
- Four: prickly pear, cactus stewed old duck.
- The method is equivalent to stewing the old duck with yam konjac. The time does not need to be too long. When using, add a small amount of cooked salt, and you can eat vegetables, meat, and soup. The flowers of the fairy ball can also be eaten with fried eggs and soup.
- Five: scrape the gold plate and stew the old duck.
- Ibid. Scratched gold plate, local common name. [2]
