This study to find out more about how patients take their anticancer medications and challenges related to taking cancer medications.

120 patients with Chronic Myeloid Leukemia (CML) who are currently prescribed an oral anti-cancer agent from up to 6 CCDR NCORP sites to complete a brief interviewer administered survey to assess medication adherence and related factors.

Inclusion Criteria:

• Patient is diagnosed with Chronic Myeloid Leukemia (CML) and is receiving care for CML at a participating CCDR NCORP practice,
• Patient had been prescribed one of the following oral anticancer agents for CML for ≥30 days (Imatinib, Nilotinib, Dasatinib, Bosutinib, Ponatinib). Prior use of any of these medications is allowed, as long as they have been on a stable regimen for at least 30 days prior to enrollment.
• Patient is 18 years of age or older

Exclusion Criteria:

• Patient does not speak English or requires an interpreter for medical visits
• Patient is cognitively impaired, as determined by the referring provider

Conducting brief structured interviews, to further understand potential patient characteristics and barriers associated with non-adherence of medication. With this knowledge of identified patient barriers, interventional strategies can be designed to improve CML care, monitoring and adherence.
