Aim:
To analyze the clinical and biological characteristics of adult BAL.
Methods:
We identified 22 cases (4.4%) of BAL from 496 newly diagnosed acute leukemia patients and compared them with patients with acute myloid leukemia (AML) and acute lymphoblastic leukemia (ALL).
Results:
CD34 positivity was higher in BAL (87%) than in ALL (60%, P = 0.04) and AML patients (63%, P = 0.05). The median age in the BAL group was greater than in ALL (43 vs 31 years, P = 0.04). Enlargement of liver, spleen and lymphonodes was more common in BAL (81.8%) than AML (46%, P = 0.003). Cytogenetic analysis revealed abnormal karyotypes in 56% of BAL patients. The overall completed remission rate in the BAL group (65%) was lower than in ALL (86%, P = 0.04).
Conclusion:
BAL patients showed a much higher incidence of older age, CD34 antigen expression, presence of Philadelphia chromosome, liver, spleen and lymphonodes infiltration and resistance to therapy.

01:27Disorders of Leukocytes
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune system...
01:18Distinctive Features of Adult Stem Cells vs Cancer Stem Cells
Adult stem cells
Adult stem cells are tissue-specific; hence, they divide to develop the tissue from which they originate. One type of adult stem cell is the epithelial stem cell, which gives rise to the keratinocytes in the multiple layers of epithelial cells in the epidermis of the skin. Adult bone marrow has three distinct types of stem cells:...
