Effects of a Visual Interactive LINE Chatbot on Self-Management of EGFR-TKI Related Side Effects in Patients With Lung Cancer

This study aims to evaluate a visual interactive LINE chatbot designed to support self-management of treatment-related side effects among patients with advanced lung cancer receiving epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) therapy. Patients receiving EGFR-TKI treatment often experience long-term side effects that require ongoing self-management. In this randomized controlled trial, participants will be assigned to receive either usual care alone or usual care plus access to the LINE chatbot intervention, which provides visualized and interactive educational content for symptom monitoring and self-care. The primary outcome of this study is self-management ability related to EGFR-TKI-associated side effects. Secondary outcomes include quality of life during treatment and overall satisfaction with the LINE chatbot intervention.
