Summary
Standard thyroid nodule evaluation improves with each step. Adding molecular imprinting detection (QCIGISH) significantly enhances preoperative thyroid cancer diagnosis, especially for difficult cases.
Area of Science:
- Endocrinology
- Oncology
- Molecular Diagnostics
Background:
- Current thyroid nodule evaluation uses ultrasonography, serology, and fine-needle aspiration (FNA).
- The diagnostic value of quantitative chromogenic imprinted gene in-situ hybridization (QCIGISH), a molecular test, remains to be fully substantiated.
Purpose of the Study:
- To evaluate the stepwise contributions of diagnostic modalities for thyroid nodule malignancy risk.
- To investigate the diagnostic significance of QCIGISH as an adjunctive molecular test.
Main Methods:
- 114 thyroid nodules were assessed using ultrasonography, serology, FNA, and QCIGISH.
- Logistic regression models were built to predict malignancy, evaluating each diagnostic step's contribution.
Main Results:
- Ultrasonography showed an AUROC of 0.79.
- Adding serology and FNA improved discrimination (AUROC 0.82 and 0.88).
- QCIGISH further enhanced diagnostic performance to an AUROC of 0.95.
Conclusions:
- Standard clinical assessments significantly contribute to thyroid nodule risk stratification.
- QCIGISH provides more accurate preoperative evaluation, particularly for indeterminate nodules.
