Show me the roads and give me a road map: Development of a patient conversation tool to improve lung cancer treatment decision-making

•Over recent years, advances in lung cancer treatments have broadened the range of treatment options for patients.•We assessed patients’ decision-making needs and elicit feedback on the design of a lung cancer treatment conversation tool.•Patients with stage I-IV NSCLC found our conversation tool to be understandable, acceptable, and usable.•· Patients with prior cancer experiences reported better preparedness for decision-making.· Our conversation tool may help decision-making among patients without similar prior cancer experiences.
