Recent therapeutic outcomes for patients with acute myeloid leukemia and trisomy 8 (+8) who were seen at our institution were investigated. Complete remission was achieved in 85% with isolated +8, 100% with +8 and chromosomal abnormalities predictive of a favorable outcome, and 47% of patients with +8 and other, mostly complex chromosomal abnormalities. Median relapse-free and overall survivals in months were 5.5 and 12 (isolated +8), 20 and 25 (+8 and favorable karyotype), and 7.5 and 6 (+8 and unfavorable karyotype). Despite an encouraging rate of complete remission, the relapse-free and overall survivals for patients with isolated +8 were not significantly different from those of patients with +8 and unfavorable karyotypes. The presence of +8 did not appear to adversely affect the outcome of patients with favorable karyotypes.
