Why do leukemia need repeated bone puncture?

In response to this problem, experts said that the reasons mainly include the following four aspects. The following small series will introduce them to you one by one, hoping that they can be helpful to everyone. 1. Definite diagnosis For leukemia patients who have been morphologically confirmed, it is necessary to further conduct bone marrow cytochemical, immunological and cytogenetic examinations to determine the subtype of leukemia and determine its prognosis. 2. Observation of curative effect For leukemia patients who have not yet remitted, usually 10-14 days after chemotherapy, bone puncture is required to understand the treatment response of the last chemotherapy and help doctors determine further treatment plans and drug choices. 3. Judgment of prognosis If the percentage of leukemia cells in the bone marrow of the patient does not decrease significantly despite multiple regimens combined with chemotherapy, or if it decreases for a while but then rises to the level before treatment in a short period of time, it indicates that the patient has primary or secondary leukemia cells. Regenerative drug resistance is more difficult to treat and has a poor prognosis. 4. Monitoring of disease changes For patients who have achieved complete remission after chemotherapy, although the bone marrow image is nearly normal, they should still be regularly reviewed. The purpose is to detect changes in the disease as soon as possible and give timely and effective treatment.
