Overview
This study intends to adopt a prospective longitudinal research design to comprehensively evaluate patient-reported emotional stress and symptom burden in patients with advanced lung cancer and lung cancer brain metastasis during first-line and maintenance treatment, extract symptom clusters, and describe the longitudinal dynamic trajectories of symptoms and symptom clusters over time. Meanwhile, it analyzes the relationships between brain metastasis and emotional stress as well as symptom trajectories.
Patients will be divided into three cohorts according to the status of brain metastasis: non-metastasis, stable brain metastasis, and progressive brain metastasis. Differences in emotional stress, symptom burden and symptom cluster manifestations among subgroups will be further compared, together with their correlations with brain metastasis. This study aims to improve the understanding of the characteristics of symptom burden and symptom cluster profiles mediated by emotional stress in lung cancer patients throughout treatment.
