This table indicates the frequencies of antigen expression at diagnosis and at relapse in 153 adult patients with de novo acute myeloid leukemia enrolled in CALGB 8361. Testing was performed by multiparameter flow cytometry in a single reference laboratory. Those antigens present in the majority of the cases are shown in bold type.
