Evidence for a 15;17 translocation in every patient with acute promyelocytic leukemia

R A Larson et al. Am J Med. 1984 May.

Abstract

Cytogenetic specimens were obtained from blood or bone marrow in 27 patients with acute promyelocytic leukemia, including four with the microgranular variant. A 15;17 translocation was identified in 21 to 100 percent of metaphase cells from all 27 patients. The structural rearrangement was identical in every case, and the breakpoints were assigned to 15q22 and 17q21.1. Twelve patients had complete remission, and two (both with the microgranular variant) have had unmaintained continuous remission longer than four years. These data indicate that the 15;17 translocation may be found in every patient with acute promyelocytic leukemia if optimal chromosome analysis is performed.
