The recurrence of gene positivity after bone marrow transplantation suggests the possibility of disease recurrence.
Generally, the fusion gene is negative after successful bone marrow transplantation. If the gene is positive within a short period of time after bone marrow transplantation, but other indicators are normal, the first consideration is the body’s rejection reaction, and it is necessary to go to the hospital for rechecking and observing whether there is fever, cough, diarrhea, rash, etc., so as to timely and appropriately treat the symptom.
If it has been a long time after the bone marrow transplantation and the gene has changed from negative to positive, it is highly suspected that there is a recurrence of the disease, and it is recommended to further perform bone marrow aspiration, peripheral blood smear, blood routine and other tests, and then perform another bone marrow transplantation if necessary.
After bone marrow transplantation, patients should pay attention to a balanced diet and regular review. If the gene is positive again, it is recommended to consult a doctor in time for treatment under the guidance of a professional doctor.
