Objective:

To investigate plasma metal levels, their association with diet, and potential links to molecular features in papillary thyroid carcinoma (PTC), highlighting the significance of these factors in thyroid tumor risk.

Approach:

Key Findings:

• Patients with thyroid disease exhibited significantly altered plasma elemental profiles compared to healthy controls.
• Dietary habits significantly influenced elemental concentrations, with specific foods linked to elevated metal levels.
• Alterations in elemental profiles correlated with abnormal thyroid hormone levels, indicating potential clinical relevance.
• The BRAF V600E mutation was identified in 51% of PTC cases, showing a non-significant association with higher mercury and cadmium levels.

Interpretation:

The study reveals distinct alterations in plasma metallic element profiles in patients with PTC, influenced by dietary habits, suggesting potential avenues for intervention.

Limitations:

• The study is limited to a specific geographic region (Hanzhong, China), which may affect generalizability.
• The association between BRAF V600E mutation and metal levels was non-significant, indicating further research is needed, and potential biases in case-control studies should be considered.

Conclusion:

The findings provide insights into the interaction between lifestyle factors and the molecular pathogenesis of thyroid tumors, emphasizing the need for further research to validate these findings.
