OBJECTIVE: We describe discussions about the lung cancer treatment decision-making process across the patient journey from the perspective of patients and caregivers with diverse experiences of living with lung cancer. METHODS: Patient preference studies show individuals with lung cancer usually favor more aggressive treatments despite adverse events (AEs), in pursuit of better survival. However, patients are frequently passive in treatment decisions, suggesting there are barriers impairing patients' abilities to engage in shared decision-making. To explore this further, we asked patients with epidermal growth factor receptor-positive lung cancer and their caregivers to complete surveys and participate in focus group discussions facilitated by research specialists. RESULTS: US patients with lung cancer ( CONCLUSION: Healthcare providers should distribute reliable educational materials and have early conversations with patients on individual lung cancer treatment, health-related quality of life goals, potential AEs, and distinguishing AEs from disease progression symptoms.
