In the last decade, the development of imatinib, a tyrosine kinase inhibitor, has brought about unprecedented change in the way newly diagnosed, chronic-phase chronic myeloid leukemia patients are treated. Two next-generation tyrosine kinase inhibitors, nilotinib and dasatinib, were initially indicated for imatinib-resistant or imatinib-intolerant chronic myeloid leukemia patients and recently received approval from the Food and Drug Administration for treatment of newly diagnosed, chronic-phase chronic myeloid leukemia patients. In comparison with the previous standards of care, benefits with these three tyrosine kinase inhibitors have included more rapid response rates, increased survival, and fewer side effects. The improved long-term outcomes have altered the approach to management of chronic myeloid leukemia from a progressive fatal disease with a poor prognosis to a chronic condition similar to diabetes or hypertension. Prolonged survival increases the need for patient education, support, monitoring, and assistance with adverse event management. Even low-grade side effects can adversely affect patients' quality of life and, therefore, require prompt attention to prevent long-term complications or suboptimal outcomes. New evidence has indicated that patient adherence to tyrosine kinase inhibitor therapy is essential to successful treatment. Midlevel practitioners can help to optimize outcomes by educating patients regarding the importance of adherence, performing regular monitoring, helping patients to understand their test results, and aggressively managing treatment-related side effects.
