Abstract

Background: Chronic myeloid leukemia (CML) is myeloproliferative clonal neoplasm. Imatinib has greatly improved CML prognosis. Many prognostic scoring systems have been developed for CML risk stratification. In clinical practice, 3 systems are widely used: Sokal, Hasford and European Treatment Outcome Study (EUTOS). Recently, EUTOS long-term survival (ELTS) score is the first long-term scoring system that considered specifically CML-related death. Therefore, the aim of the present study was to validate the effectiveness of Sokal, Hasford, EUTOS and ELTS scoring systems in predicting the outcome in Egyptian CML-chronic phase (CML-CP) patients treated with imatinib.
Patients and methods: Retrospective study performed on 167 patients with CML-CP who were treated with imatinib. Using the Sokal, Hasford, EUTOS and ELTS scores, we divided the patients into each risk groups.
Results: Significant differences in event free survival (EFS), time without progression (TWP) and overall survival (OS) prediction between the Sokal, Hasford and ELTS risk groups, but no significant difference among the EUTOS score risk groups.
Conclusion: Our study indicates that Sokal, Hasford and ELTS scoring systems but not the EUTOS score are effective in predicting early treatment response, EFS, TWP and OS for Egyptian CML patients treated with imatinib
