Abstract

Background: Nonadherence in cancer patients taking oral anticancer drugs is common. Reasons for nonadherence are still not really understood as influencing factors are often complex, dynamic, and interrelated. Objective: A qualitative study was conducted to gain insight into (non-)adherence behavior in patients taking oral tyrosine kinase inhibitors by exploring (1) processes and factors influencing (non-)adherence and (2) their interrelatedness. Methods: Semistructured interviews were held with 30 patients of different ages and with different types of cancer. A grounded theory approach was used. Results: Three foci were found when dealing with oral tyrosine kinase inhibitors: (1) a focus on survival, (2) a focus on quality of life, and (3) a balance between survival and quality of life. The process of adherence was determined by a set of complex and interrelated influencing factors: treatment-related side effects, hope, anxiety, trust, and feedback mechanisms. Conclusions: This qualitative study gives insight into processes and factors influencing (non-)adherence behavior in patients taking oral tyrosine kinase inhibitors. The results of this study can help healthcare professionals understand why patients taking oral tyrosine kinase inhibitors do not always adhere to their therapy. Implications for Practice: Conditions should be created by which patients get maximum opportunity to establish a balance between survival and quality of life. An open climate and a trust-based relationship should be established in which patients feel comfortable to openly discuss their therapy and the difficulties they experience.
