title: Cytogenetic evidence of clonal evolution in 5q- anemia.
abstract: The clinical homogeneity of myeloproliferative syndromes associated with a 5 q- marker can be contested, but nevertheless finds support in the 2 case reports we have cited. One of these observations of refractory anemia with partial myeloblastosis and 5 q- marker has shown a transformation into an acute myelomonocytic leukemia with clonal chromosomal evolution.
