Why do leukemia patients have to do multiple bone marrow aspirations?

┳ Need for diagnosis.

To diagnose leukemia, a bone marrow biopsy is required. For leukemia patients who have been morphologically confirmed, it is necessary to further conduct bone marrow cytochemical, immunological and cytogenetic examinations to clarify the subtype of leukemia and determine its prognosis.

┳ Observe the curative effect.

Leukemia patients need to do bone marrow aspirate in the process of treatment, this is to see the curative effect. For leukemia patients who have not 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 options and drug choices.

┳ Judge the prognosis.

The effect of treatment can be seen through bone marrow aspiration, and the doctor can judge the prognosis based on these. If the percentage of leukemia cells in the bone marrow of a patient does not decrease significantly despite multiple regimens combined with chemotherapy, or if the percentage of leukemia cells in the bone marrow decreases once but rises to the level before treatment in a short period of time, it indicates that the patient's leukemia cells have primary drug resistance, and it is relatively Refractory, poor prognosis.

┳ Monitor changes in condition.

After treatment, the patient may also have a bone marrow aspirate on a follow-up examination. 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 condition as soon as possible and give timely and effective treatment.
