M. Yagci et al., Therapy-related refractory anemia with ringed sideroblasts in chronic lymphocytic leukemia: involvement of 3q21 region, CANC GENET, 129(1), 2001, pp. 43-46
Therapy-related myelodysplastic syndrome/acute myelogenous leukemia (t-MDS/
AML) is extremely rare in chronic lymphocytic leukemia (CLL) despite extens
ive use of alkylating agents. We present a case of heavily treated CLL with
resultant therapy-related refractory anemia with ringed sideroblasts (RARS
). A complex cytogenetic abnormality including involvement of 3q21 was dete
cted and to our knowledge, is the first report of a RARS case with a 3q21 a
bnormality. (C) 2001 Elsevier Science Inc. All rights reserved.
