These abnormalities were related to immunophenotypic markers as This study prospectively analysed the relationships between immunophenotypic and cytogenetic features of blast cells in 432 acute non-lymphoblastic leukemias (ANLL) at presentation. In agreement with previous studies, no immunophenotypic features (other than monocytic differentiation) predicted the presence of an 11q23 rearrangement. While morphologic assessment of blood smears, bone marrow smears, and tissue sections remains the cornerstone of lymphoma and leukemia diagnosis and classification, immunophenotyping is a very valuable and important complementary tool. Specific features were seen in five ANLL entities: M0 or M1/B lineage antigen positivity/t(9;22) or del(11)(q23); M2/CD13-/t(8;21); M4/CD13+, CD34+, CD36+/inv(16); M4 or M5/lack of B lineage antigen/del(11)(q23) or t(9;11).
