Experiences of Advanced Non-Small Cell Lung Cancer Patients with Targeted Therapy Using Journey Mapping: A Qualitative Study

Targeted therapies against specific driver gene mutations have become the standard first-line treatment for most patients with advanced non-small cell lung cancer (NSCLC). While these therapies significantly prolong survival, the entire cancer treatment journey remains challenging and distressing. To better understand these experiences, this study employed a qualitative descriptive approach, conducting semi-structured interviews with 18 advanced NSCLC patients receiving targeted therapy, supplemented by patient journey logs. The resulting journey map delineated five stages: diagnosis, initial treatment, maintenance therapy, disease progression, and end-of-life. The analysis identified four key themes characterizing patient experiences at each stage. These findings enable healthcare professionals to identify risk situations and determine optimal timing for support interventions. Similarly, preparing patients for the processes they must undergo and the side effects of medical treatment helps reduce their uncertainty and anxiety, thereby improving their quality of life.
