Cerebellar vermis tumor

Any tumor in the body is very painful for people and will cause great emotional fluctuations. Bad emotions have a very negative impact on treatment. Among the numerous tumors, brain tumors are the most difficult to treat and are considered a high-risk area during surgery. However, most cerebellar vermis tumors require surgery to alleviate the condition. Although it is difficult, the risk is even greater if not treated.

Medulloblastoma is a highly malignant tumor originating from residual embryonic tissue and is classified as a grade 4 tumor (WHO). The peak incidence is between 5 and 15 years old. It is rare in adults, with a higher incidence in boys. The male-female ratio is 2:1, which is consistent with the incidence of medulloblastoma in children. Medulloblastoma can occur at any part of this transition process, but is limited to the posterior cranial fossa. The typical site of medulloblastoma is the top of the fourth ventricle and the cerebellar vermis, and the tumor can grow in all directions. After filling the fourth ventricle, the tumor can grow into the occipital cistern and the spinal canal through the median foramen; it can extend into the pontocerebellar angle cistern through the lateral foramen; and it can reach the third ventricle through the cerebral aqueduct. Tumor cells can easily metastasize in the ventricles and subarachnoid space through the cerebrospinal fluid. Adult medulloblastoma is atypical in location and can deviate from the midline.

Brainstem tumors were previously considered a "forbidden zone" for surgery because the brainstem contains many nerve nuclei, conduction bundles, and reticular structures in a very small area. Most brainstem tumors are gliomas that grow in an infiltrative manner, so surgery is difficult and can easily cause damage to important structures in the brainstem. Surgical disability and mortality rates are high, and the prognosis is poor. In recent years, with the rapid development of microneurosurgical technology, the surgical effect of brainstem tumors has been significantly improved. Although brainstem tumor surgery still has a high risk, surgical resection should be actively used for tumors that are more limited, nodular or cystic, and well differentiated, and the prognosis is better. For benign brainstem tumors, total resection surgery can achieve a radical cure. It is recommended to cooperate with targeted Chinese medicine treatment to relieve symptoms, improve immunity, improve quality of life, and prevent further metastasis and recurrence.

" Chemotherapy for brain tumors is an important treatment method for this disease. It is treated by interfering with the metabolism of anti-tumor. Adjuvant chemotherapy can indeed greatly improve the survival rate of patients after surgery, but there are still many problems to be solved in chemotherapy. The most serious one is that chemotherapy drugs "do not distinguish between friend and foe", that is, while killing cancer cells, they also kill normal cells in the body that reproduce rapidly, causing patients to have side effects such as hair loss, loss of appetite, oral ulcers, diarrhea, and leukopenia. Therefore, most doctors currently advocate 4 to 6 weeks of chemotherapy after surgery. In order to reduce the side effects of nausea and vomiting after chemotherapy, it is recommended to take modern Chinese medicine ginsenoside Rh2 (life-protecting factor), which can play a role in reducing toxicity and increasing efficacy. The use of ginsenoside Rh2 capsules (the best absorption content for the human body is 16.2%) after surgery, radiotherapy and chemotherapy can also play a certain role in preventing recurrence and metastasis.

To a certain extent, adjuvant chemotherapy only increases the insurance factor for the patient's survival. Overall, it can reduce the chance of recurrence by 1/4 and the chance of death by 1/6. For this reason, brain tumor patients must receive chemotherapy after surgery. "
