Abstract

Purpose: To estimated the survival rate and indentify factors associated with treatment effectiveness in CML patients receving Imatinib over a 5 years period at the National Institue of Hemathology and Blood Transfusion. Patients and methods: this was a descriptive study of 798 CML patients with Ph (+) receving Imatinib in National Institute of Hematology and Blood Transfusion from January 1, 2019 to December 31, 2023. Results: At 5 years, the estimated rate of overall – survival was 89,5%, progress - free survival was 84,8%, event - free survival was 78,7%. Prognotic factor influencing treatment effectiveness and survival rate included risk grouping, Imatinib dose reduction and achieving early molecular response after 3 months. Conclusion: Treatment of chronic phase CML with Imatinib for patients not classified as high risk remains highly efective, helping to prolonged overall survival, progresstion free survival and event free survival.
