title: Cytogenetic and clinical studies in acute promyelocytic leukemia (M3) and cytologic M3 variant (M3V).
abstract: Cytogenetic specimens were obtained from bone marrow 24-hour cultured cells in 22 patients with acute promyelocytic leukemia, including six with microgranular variant. A t(15;17) was identified in 10-100% of metaphase cells from 13 patients. We have found no correlation between complete remission percentage and karyotype. Our data suggest that each laboratory, as far as M3 and M3V are concerned, must study its own culture time as it relates to numerous parameters involving tumoral cell kinetics.
