First of all, not all leukemia patients need bone marrow transplantation. The treatment schemes of leukemia mainly include the following categories: chemotherapy, radiotherapy and traditional Chinese medicine treatment. Some high-risk patients need bone marrow transplantation. In recent years, with the progress of molecular biology and biogenetics, the prognosis of leukemia has been greatly improved. "Leukemia is incurable" has become a thing of the past. Regular and systematic treatment can make most leukemia patients live disease-free for a long time, or even recover.
Since you mentioned bone marrow transplantation, the following is a description of bone marrow transplantation (for reference only)
The so-called bone marrow transplantation is not literal, but real bone marrow. Medical scientists found in the early research and treatment of leukemia that human bone marrow is the source of hematopoiesis, and bone marrow contains infected blood cells! Limited by the conditions at that time, they often take healthy bone marrow directly and transplant it into patients after proper treatment, so this treatment method is called bone marrow transplantation. Since then, the name has continued.
With the deepening of medical research and the application of advanced medical equipment, medical scientists have found hematopoietic stem cells in human bone marrow, and found that not only bone marrow contains hematopoietic stem cells, but also blood contains hematopoietic stem cells, but the content is far less than bone marrow! Because the method of extracting directly from bone marrow will bring great pain to donors, the method of separating hematopoietic cells from blood is adopted, thus minimizing the pain of donation.
The separated blood will be reinjected into the donated blood vessels, and the stem cells will be left in another container for transplantation. Of course, the separator is strictly disinfected, and you don't have to worry about blood being invaded by germs when traveling.
In addition, human bone marrow can produce hematopoietic stem cells without worrying about the lost part. Within 10 days, the stem cells in the donor will return to the original level.
In addition, of course, bone marrow transplantation also has its disadvantages: 1, bone marrow transplantation violates the laws of physiology and nature. 2. Destroy the immunity of life
3. Difficulties in matching.
