Clinical and biologic characteristics of @entity4587 + XXXX . Our experience and literature review.

@entity1 @entity1261 @entity3052 @entity4587 @entity7639
Six @entity1 with @entity3052 ( @entity3052 ) expressing @entity4587 antigen ( @entity4587 + @entity3052 ) were studied. They consisted of five @entity1 with M1 and one with an M2 morphology. Two cases expressed other lymphoid-associated antigens, in addition to @entity4587 . The complete remission rate was 50%. One @entity1 had central nervous system recurrence. Cytogenetic analysis demonstrated normal karyotypes in all the cases. All but one had germline configurations of the T-cell receptor (TCR) genes and @entity7639 gene. However, all did not have detectable recombinase activating gene-1 activity by the RT-PCR technique. We performed colony formation assay in two @entity1 , and no enhancement of colony formation by @entity1261 was noted. The results presented here, together with those reported previously, suggest that @entity4587 + @entity3052 may demonstrate lineage infidelity.
