WebEvolution of the neoplastic clone may be associated with development of new abnormal karyotypes, often an extra chromosome 8, isochromosome 17q [i(17q)], or reduplication of bcr-abl. Further evolution may lead to a blast phase with myeloblasts (60% of patients), lymphoblasts (30%), megakaryoblasts (10%) and, rarely, erythroblasts.
