Brain metastasis A refers to the transfer of tumor cells originating from other parts of the body into the brain, and its incidence accounts for 3.5%-10% of intracranial tumors. Most brain metastases have a chronic onset, but the course of the disease often progresses rapidly. Most patients have symptoms of central nervous system dysfunction, including headache, nausea, vomiting, speech impairment, loss of limb strength, ataxia, cranial nerve palsy and so on. The surgical treatment of brain metastases is usually to remove the primary lesion first and the metastatic lesion later. However, in cases where the symptoms of intracranial hypertension are obvious and affect the patient’s life, the intracranial lesions can also be removed first, followed by the primary lesions. For those whose primary lesions have been widely metastasized and cannot be operated, the intracranial lesions can also be removed to relieve the disease and prolong life; regardless of whether the patient is treated by surgery or not, if the patient is in good general condition, with normal blood and liver and kidney functions, chemotherapy can be administered. For those whose primary tumors cannot be removed, have multiple metastases in the body and are in very poor general condition, surgery is not recommended. Combined Chinese medicine has better advantages in the treatment of brain tumor: the use of Chinese medicine before surgery can improve the functional state of the body and strengthen the body constitution; after surgery, the use of drugs to benefit the qi and strengthen the surface of the body and nourish the blood is conducive to the early recovery of surgical trauma; long-term use of Chinese medicine to support the root and invigorate blood circulation and remove blood stasis is expected to prevent or delay the recurrence and metastasis of tumor. The combination of Chinese herbal medicine with radiotherapy, chemotherapy and immunotherapy can improve the overall efficacy and alleviate the adverse effects such as immune deficiency brought about by radiotherapy. Traditional Chinese medicine treatment can also be used for patients who are not suitable for surgery, radiotherapy and chemotherapy. Dialectical treatment according to the principles of clearing heat and detoxification, softening and dispersing hard nodes can often achieve the goal of reducing symptoms, improving the quality of survival and prolonging life. Typical case: Ms. Ren, 67 years old, had her left kidney removed due to kidney cancer in 2002. At the end of 2011, she developed a pronounced cough with numbness and weakness in the right hand, and went to the hospital to check and found that there was a tumor in the lung and it had metastasized to the brain. He had a numbness and soreness in the right upper limb with numbness and swelling, and a bruised tongue with obvious marginal teeth marks. After taking 14 pills, the patient’s spirit improved significantly and the chest tightness and palpitations disappeared. After continuing to take the medicine for 3 months and adding acupuncture and fire curing point massage, Ms. Ren’s cough improved and the numbness and weakness of her right hand also improved significantly. In view of her improved general condition, she was in a position to undergo surgery, so the surgery was performed under general anesthesia to safely remove the two larger tumors in the brain. After the surgery, the patient continued to take Chinese medicine, and now she is in good spirits, eats well, sleeps well, and her quality of life has been greatly improved. In conclusion, using the concept of combining Chinese and Western medicine, combining the evidence-based treatment, which is the strength of Chinese medicine, and the disease-based treatment, which is the strength of Western medicine, is expected to provide brain tumor patients with a comprehensive treatment plan that is both inexpensive and effective.
