| Description | Reported here are 72 previously treated Philadelphia chromosome-positive (Ph+) CML patients on imatinib (IM) therapy, with a focus on patients with additional chromosomal aberrations (CAs). At the start of IM treatment, 49 patients exhibited only the Ph chromosome (68%) and 23 patients (32%) had one or more additional CAs. There was no statistically significant difference in the overall survival of patients with additional CAs and patients with Ph as the sole abnormality. Patients in accelerated phase had significantly worse overall survival on IM, regardless of additional CAs. The present results confirm that the majority of previously treated Ph+ CML patients benefit from starting IM therapy, including patients with defined additional changes. In contrast, patients with complex karyotypes have poor prognosis, even with IM. |
