If the blood system is abnormal and you are suspected of having leukemia, you must go to a regular hospital, where the first bone marrow aspiration is important, and you must also check the bone marrow morphology, immunophenotyping, chromosomes and leukemia genes, and you must freeze the leukemia vaccine where available. Because of the different types of leukemia and the different genetic and chromosomal abnormalities that determine the outcome of the patient’s treatment. That is why it is very important to perfect the tests. In addition, when leukemia undergoes standard chemotherapy regimen with poor results, do not keep changing the regimen chemotherapy, it is recommended to do transplantation directly, now with the improvement of transplantation technology and level, relapsed refractory leukemia has achieved very good results, do not insist on the old view that you cannot do transplantation without remission, if you insist on this old view, you may lose the opportunity to transplant and the patient may lose his life. So whether a patient with leukemia can survive or not largely depends on whether the patient and family are very rational and choosing the right direction of treatment is crucial.
