Among T-cell populations outside the thymus, phenotypes associated with malignancy included 1) loss of pan-T antigens (including loss of the beta chain of the T-cell antigen receptor), 2) coexpression or loss of T-subset antigens, 3) Leu-6+ T-lineage, and 4) MB-1+ T lineage. Flow cytometric immunophenotyping evaluates individual cells in suspension for the presence and absence of specific antigens (phenotype). Overall, del(13q14) and +12 were the most common abnormalities (39%), whereas del(11q13), del(17p13), and del(6q23) were detected only in 3, 1, and 0 cases, respectively.
