Mindfulness-Oriented Respiratory Distress Symptom Intervention for Patients With Lung Cancer: A Feasibility Randomized Controlled Trial
Lung cancer is the leading cause of cancer mortality, posing a critical public health challenge in both Hong Kong and global populations. Patients with lung cancer frequently experience a distressing symptom cluster characterized by breathlessness-driven respiratory distress, accompanied by persistent cough and fatigue, which collectively impose a substantial disease burden. While our research team leader previously developed and validated a multi-component Respiratory Distress Symptom Intervention (RDSI) in England, demonstrating clinical efficacy for lung cancer management, its impact on psychological distress (anxiety and depression) proved limited. This limitation may reflect insufficient integration of psychological components, a crucial consideration given the well-established bidirectional relationship between respiratory symptoms and psychological distress. Emerging evidence indicates that mindfulness interventions provide dual therapeutic benefits by improving patient adherence and effectively addressing both physical symptoms, such as breathlessness and fatigue, as well as psychological distress, including anxiety and depression. Meanwhile, current evaluation methodologies have mainly focused on behavioral data collection, such as self-reported questionnaires, to reflect the effect before and after the intervention. Neuroimaging data can help understand the brain mechanisms underlying breathlessness and elucidate the effectiveness of interventions, thereby improving intervention strategies.
