Experiences of the fatigue-pain-sleep disturbance symptom cluster among patients with lung cancer: A descriptive qualitative study

The fatigue-pain-sleep disturbance symptom cluster presents in varying patterns and exerts profound multidimensional impacts on patients with lung cancer. Patients recognize the cluster by perceiving the sequential and interconnected onset of symptoms. Coping strategies span cognitive reframing, proactive self-management, and passive endurance. Future research should integrate subjective experiences with objective assessments to refine core symptom cluster identification, tailor individualized intervention targets, and develop effective management strategies. Empowerment-based approaches may support patients who engage actively in coping, while knowledge-based guidance and emotional support are essential for those who adopt more passive strategies.
