What is the significance of bone puncture examination

Bone marrow aspirate is one of the important test methods for blood system diseases. The cytological examination of the bone marrow smear can be used to understand the formation of various cells in the bone marrow, the changes in the morphology and composition of various cells, and the discovery of abnormal cells, so as to confirm the diagnosis, observe the curative effect, and estimate the prognosis. The significance of bone marrow examination is as follows: 1. Bone marrow examination can be used for the diagnosis of hematopoietic diseases, such as the differential diagnosis of leukemia, the identification of various anemias, the diagnosis of multiple myeloma and thrombocytopenia or diseases. 2. For some malignant tumors, whether there is bone marrow metastasis can be determined by bone marrow examination, because the bone marrow is a good site for the metastasis of many malignant tumors. For example, lung cancer, breast cancer, gastric cancer, and prostate cancer are prone to bone marrow metastasis, and corresponding tumor cells can be found in bone marrow examination. 3. Bone marrow examination can also be used for bone marrow culture of some infectious diseases, such as infective endocarditis, which helps to improve the positive rate of diagnosis of the disease. The protozoa is found and the diagnosis is made. 4. For bone marrow stem cell culture, chromosome karyotype examination, bone marrow cell immunological typing test, etc. In addition, during chemotherapy in patients with hematological diseases or when malignant tumors with bone marrow metastases are suspected, bone marrow examinations may be performed multiple times or periodically to determine disease progression and treatment effects. At this time, the patient should actively cooperate with the doctor for bone marrow examination. You also want to know: how to treat myelofibrosis
