Abstract/OtherAbstract:
We analyzed in vitro growth characteristics of bone marrow mononuclear cells (BMMCs) from 322 patients with acute myeloid leukemia (AML) in relation to cytogenetic abnormalities. Median colony growth was low in each of the cytogenetic changes associated with a favorable outcome. Most karyotypic abnormalities in the intermediate prognosis group were associated with low growth potential, but 11 q23 abnormalities exhibited 8 times higher in vitro growth. Cytogenetic changes that included abn(3q) seemed to display the highest colony growth in the unfavorable prognosis group, whereas isolated -7 may have been associated with limited growth potential. In vitro growth behavior was predictive of neither rate of complete remission (CR) nor survival of AML patients within the 3 cytogenetic risk groups. In contrast, colony growth differed significantly in the subgroup of patients with a normal karyotype who achieved remission with induction treatment and those who had no remission (10 versus 81.5/10(5) BMMCs; P = .015). Significantly more patients with normal cytogenetics and colony growth below the 50th percentile went into CR than did patients with colony growth above the 50th percentile (82.8% versus 71.2%). Only 4 (6.8%) of the patients in the low growth group had no remission, compared with 12 (23.1%) of the patients with higher in vitro growth (P = .031, chi-square test). In conclusion, colony growth may prove useful as a prognostic factor for early treatment failure in AML patients with a normal karyotype.
