1. The malignancy of medulloblastoma. Medulloblastoma is a malignant tumor, WHO 2007 class IV (the most malignant class of neurological tumors), all medulloblastoma is “cancer” in the eyes of the people. However, medulloblastoma can be divided into many different types, such as the pathological type of the tumor, the degree of surgical resection, whether the tumor spreads or not, and so on, which can classify the patient’s condition into several different risk levels. The simplest of these is the two divisions: the average risk group and the high risk group. The former has a better probability of survival, while the latter has a very low probability of survival. 2. How long can a child with medulla oblongata live? This is the main concern of the parents of the affected children. According to the current domestic and international literature and our long-term follow-up results, the 5-year survival probability of all medulloblastoma cases is about 50-60%. This is a statistical concept, which means that more than half of the children are still alive after 5 years; for a given family, a child can be considered to have a 50-60% chance of surviving beyond 5 years after standard treatment (this is a crude and unscientific statement, because each child’s condition is different). It is generally believed that after 5 years, the probability of recurrence of medulloblastoma is low and there is a high hope that the child can live for a long time, but there is still a low probability of recurrence; 3. The prognosis of certain types of medulloblastoma is poor because of the biological nature, the site of growth and dissemination, and the special growth and developmental stage of children: according to our experience, the majority of children with large cell or interstitial medulloblastoma and those with dissemination at the time of tumor discovery (such as patients with implants in the saddle area and spinal cord) have a short survival time. For the latter type of patients, especially if the child is very young, it makes sense to forgo treatment if the child’s family is in poor condition. The former type of patients cannot be diagnosed before surgery, and the tumor must be surgically removed to determine the pathological type before the approximate prognosis can be determined. 4. Another type of patient with a poorer prognosis is the child with classic medulloblastoma under the age of 3. The prognosis for children under the age of 3 is still acceptable because the central nervous system is highly sensitive to radiation, so radiation therapy cannot be used after surgical removal of the tumor, and even if radiation therapy is used, the dose and scope are difficult to meet the requirements, so the probability of recurrence is higher and the prognosis is poor. The prognosis is acceptable, but the treatment is mainly chemotherapy, which is expensive and difficult for many primary hospitals to carry out, so it is difficult for families with poor economic conditions to afford. 5. The clinical prognosis mentioned above is that children need to adopt radiotherapy and chemotherapy after the removal of tumor. If the tumor is removed without radiotherapy, it is meaningless and the tumor will recur soon. In addition, we would like to remind parents that there is no credible evidence to prove that any traditional medicine (TCM, including acupuncture and other traditional “therapies”), so-called “ancestral recipes” and any health food have any definite significance for the treatment of children with medulla oblongata. We hope that parents will choose carefully. 6.The cost of medulla oblongata treatment. The cost of neurosurgery + radiotherapy + chemotherapy is between 100,000 and 300,000 for the family. The final expenditure depends on many factors, such as the equipment and type of radiotherapy, the chemotherapy plan and whether it can be reimbursed, and the payment ratio of various types of insurance. For families who are not so well-off, after surgery to remove the tumor, they can choose the more common radiotherapy in their local area, so that the total cost can be controlled between $50,000 and $100,000 (if chemotherapy is not chosen). Chemotherapy has now become an essential treatment for medulloblastoma, but its clinical significance is less than that of surgery and radiotherapy, so for such families, chemotherapy may not be chosen, but it will affect the survival time of the child and is not recommended by the formal treatment guidelines. 7. For families with better economic conditions, more standardized radiotherapy patterns and chemotherapy are recommended, but their costs will also increase exponentially. There are also many families inquiring whether to go to developed countries or regions such as Europe and America for treatment. For the average working class, it is not recommended to go abroad for medical treatment: domestic medical costs are extremely low compared to developed countries; although the medical level in the United States is higher than that in China, it is only limited to a few large medical centers. As the domestic medical reform continues to deepen and the medical infrastructure is further improved and optimized, the patient’s medical experience will be more comfortable. 8, there is another problem need to add, many parents want to ask a question is: I pay so much money and time, and finally the child is not preserved, what do I do? As a brain surgeon, I’m used to seeing life and death, and I’ve seen a lot of human emotions, so I really have no answer to this question. This involves a question of life values, and a thousand people have a thousand answers. I will give you an excerpt from a quote I once read: “In order to participate in the growth of a life, participation means giving and appreciating, the child does not want to be perfect, does not have to fight for my face, does not have to pass on my family, and does not have to help me in my old age, as long as this life exists and walks in this beautiful world, so that I have the opportunity to walk with her (him) for a while “.
