Association between circadian rhythm disruption and the risk of malignancy in patients with thyroid nodules: a propensity score-matched study
To investigate the association between cumulative circadian rhythm disruption (CRD) and the risk of malignancy and aggressiveness in patients with thyroid nodules, particularly in light of the rising incidence of thyroid cancer.
Key Findings:
A strong, dose-dependent relationship between CRD and malignancy risk was observed, with adjusted odds ratios (aOR) for malignancy being 1.58 (95% CI: 1.15–2.15) for Low CRD, 1.85 (95% CI: 1.30–2.62) for Moderate CRD, and 2.95 (95% CI: 2.05–4.25) for High CRD.
Increasing CRD severity was associated with aggressive clinicopathological features, including multifocality and lymph node metastasis.
High CRD was the strongest independent predictor for lymph node metastasis.
Interpretation:
Cumulative CRD is independently associated with both the presence of malignancy and aggressive progression of thyroid cancer in patients with thyroid nodules, suggesting that circadian health may be a modifiable risk factor with significant implications for clinical practice.
Limitations:
The study is observational and may not establish causation.
Potential biases in self-reported data on lifestyle factors.
Generalizability may be limited to specific populations undergoing thyroidectomy.
Unmeasured confounders may impact the results.
Conclusion:
Assessing a patient’s circadian health could serve as a novel, modifiable factor for risk stratification in thyroid cancer management, highlighting the importance of lifestyle interventions.
