Official Title: Are the Secondary Chromosome Abnormalities Seen in Chronic Myeloid Leukemia (CML) Cells Induced to Ph-Chromosome Negativity by Imatinib a Result of Chromosome Instability
Brief Summary: In order to distinguish between clonal instability driven by imatinib in CML and actual changes with secondary clones induced by imatinib we would like to investigate the karyotype of non-CML patients treated with imatinib such as GIST patients.
