Granulocytic sarcoma is associated with the 8;21 translocation in acute myeloid leukemia.

Abstract

Our data suggest that this association is more common than generally recognized and may be specific. Patients with t(8;21) should be observed closely for signs and symptoms of granulocytic sarcoma. These patients may have a less favorable prognosis than other patients with t(8;21). Cooperative oncology groups should retrospectively identify patients with AML and t(8;21) who had a poor outcome to determine if they had a disproportionate incidence of granulocytic sarcoma. If so, aggressive therapy such as bone marrow transplantation may be warranted early in the therapeutic strategy.
