title: Ring chromosomes and hematologic disorders.
abstract: Based on 5 years of cytogenetic evaluation in hematology, we report our observations on various hematologic proliferative disorders with ring chromosomes. Comparing our data to those previously published in the literature we analyzed the occurrence of the ring in relation to the age of onset, previous history of therapeutic or professional exposure to mutagenic agents, and mean survival. It is concluded that the presence of ring chromosomes may be linked to a poor prognosis.
