Chromosome changes in patients treated with "Myleran"

The aim of this study is the determination of chromosomal changes in patients suffering from chronic leucosis, after therapy with the cytostatic "Myleran", to find out whether this cytostatic causes them, because of clinical experience which indicates its value in the treatment of chronic myeloid leukemia. Patients were treated with therapeutic doses of 4 mg per os daily. Analysis with present methods in patients receiving relatively small total doses did not discover the other visible chromosomal aberrations in leucocytes in peripheral blood, except the usual aberrations caused by chronic leucosis.
