BACKGROUND: Previous research has demonstrated that many lung cancer survivors report difficulties with symptom control and experience a poor quality of life (QOL). Although recent studies have suggested a relationship of single nucleotide polymorphisms (SNPs) in several cytokine genes with cancer susceptibility and prognosis, associations with symptom burden and QOL have not been examined. The current study was conducted to identify SNPs related to symptom burden and QOL outcomes in lung cancer survivors. METHODS: All participants were enrolled in the Mayo Clinic Lung Cancer Cohort following diagnosis of lung cancer. A total of 1149 Caucasian lung cancer survivors completed questionnaires and had genetic samples available. The main outcome measures were symptom burden as measured by the Lung Cancer Symptom Scale and health‐related QOL as measured by the Short‐Form General Health Survey. RESULTS: Twenty‐one SNPs in cytokine genes were associated with symptom burden and QOL outcomes. Our results suggested both specificity and consistency of cytokine gene SNPs in predicting outcomes. CONCLUSIONS: These results provide support for genetic predisposition to QOL and symptom burden and may aid in identification of lung cancer survivors at high risk for symptom management and QOL difficulties.
