1, doctors have the responsibility to tell patients or their families about their illness, whether to explain it to their families or patients depends on the specific situation.

2. Whether the matching is successful or not needs to be sent to the blood bank for inspection. The hospital can't detect whether the matching is successful. Bone marrow transplantation is not a simple treatment. Matching usually takes ten days. Many times, the Chinese bone marrow bank can't find a suitable match. The time to find a match depends on when there is a suitable match.

3. The interval of chemotherapy depends on the specific type and the choice of treatment scheme, and cannot be generalized.

4. Bone marrow transplantation is generally performed after chemotherapy remission. Therefore, some patients can be relieved after a course of treatment, and transplantation can be considered if there is a suitable match. Some patients are still not completely relieved after four times, so the transplant time should be postponed.

Furthermore, I suggest that you provide detailed information, including the patient's age, leukemia type, blood routine and bone marrow puncture, immunophenotype, chromosome and genetic results, which will help you make a more specific analysis. In addition, bone marrow transplantation is not the best choice for leukemia patients and should be carefully considered. Because your question is not targeted and your answer is not targeted, but I hope you are satisfied.
