[Importance of cytogenetic investigations in canine leukemias].

Abstract

Like in man, in neoplastic haematopoietic diseases of the dog genetical changes can be detected cytogenetically. In this study, some cytogenetically characterized cases are presented and discussed against the background of comparable cases reported in the literature. In two out of three patients investigated, one or two extra copies of chromosome 1 were detected. Corresponding changes have also been described in two other cases in the literature.
