Abstract

Purpose
Lung cancer (LC) is the leading cause of cancer-related death globally, and understanding symptom clusters (SCs) among LC patients could improve symptom management. This scoping review provides a comprehensive summary of the most common SCs and their compositions identified in studies specifically investigating SCs of LC patients.
Methods
A scoping review was conducted following the Joanna Briggs Institute methodology. The study included LC patients as participants, SCs as the concept, and studies with distinct aim to investigate LC SCs as the context. We searched studies from inception to September 2022 in PubMed, Embase, PsycINFO, CINAHL, and the Cochrane Library databases using the terms: "lung cancer," "cancer survivors, " and "symptom cluster."
Results
Of 41 reviewed reports, 188 SCs were identified. Both a priori and de novo method were used to identify LC SCs, with exploratory factor analysis being the most commonly used statistical method in the de novo approach. The three most frequent SCs were respiratory, gastrointestinal (GI), and psychological SCs. The most common respiratory SC included cough + dyspnea. Nausea + vomiting was the most prevalent cluster membership among GI SCs. Sad + feeling irritable + feeling nervous + worrying was the most common cluster membership among psychological SCs.
Conclusion
Respiratory, GI, and psychological SCs were common among LC patients, and addressing these clusters could improve symptom management strategies. Further research on SCs across the lung cancer trajectory is essential to enhance our understanding about SCs and facilitate effective symptom management throughout the disease course.
