Abstract
Aim: To assess long-term efficacy of firstand second-line tyrosine kinase inhibitors in non-selected patients with chronic myeloid leukemia in a real-life clinical setting.
Materials and methods: The assessment is based on long-term results of a prospective single center comparative clinical trial that was based on non-selected groups of 116 patients with various stages of chronic myeloid leukemia being treated with a first generation tyrosine kinase inhibitor imatinib, and of 44 patients being treated with a second generation tyrosine kinase inhibitor nilotinib. We analyzed all-cause mortality, progression-free survival from April 2005 to April 2013, with a median of the follow-up of 128 months.
Results: In 116 patients with chronic myeloid leukemia treated with imatinib, the Kaplan-Meier survival estimate was 120 months. In 44 patients at an early chronic phase, 5-year overall survival and progression-free survival was 93.2% and 8-year overall and progression-free survival was 79.5%. In 44 patients at a late chronic stage, 5-year overall and progression-free survival was 95.5%, 8-year overall and progression-free survival, 72.7%. In 28 patients at acceleration phase, 5-years overall survival was 78.6% and 8-year overall survival, 46%. Median of overall survival in patients treated with nilotinib was not reached. During 78.6 months of combination treatment with cytotoxic agents, tyrosine kinase inhibitors of the first (imatinib) and second line (nilotinib), overall survival was 100%.
Conclusion: In clinical practice, inclusion of patients with chronic myeloid leukemia and imatinib resistance (disease relapse) or imatinib intolerance into the treatment program with frontline therapy with general cytotoxic agents and thereafter with firstand second-line tyrosine kinase inhibitors significantly improves overall survival.
