Abstract
A female patient with chronic myelocytic leukemia (CML) in chronic phase after busulfan and interferon treatment had four different cell lines in her bone marrow. In addition to cells with a normal karyotype there were cells with the Philadelphia chromosome (Ph^1^), cells with trisomy 8 and a Ph^1^, and cells with trisomy 8 as the sole anomaly.

A 23-year-old man developed Ph'-positive chronic myelogenous leukemia in 1966. After two short courses of busulfan not associated with severe myelosuppression, the frequency of Ph'-positive metaphases in his bone marrow was 40%. Over the next eight years, he remained hematologically stable without f
## Abstract Twentyβthree patients in various cytological subgroups of blast phase of Ph^1^βpositive chronic myeloid leukaemia were investigated cytogenetically. The correlation between prognosis and the cytological and cytogenetic features of blast cells was studied. The best prognosis was found in
