Summary
This study stratified thyroid nodule malignancy risk using ultrasound (US) features, emphasizing echogenicity. A four-tier system aids in predicting cancer risk and guiding fine-needle aspiration decisions.
Area of Science:
- Radiology
- Oncology
- Endocrinology
Background:
- Thyroid nodules are common, and accurate malignancy risk stratification is crucial for patient management.
- Ultrasound (US) features play a key role in assessing thyroid nodule characteristics.
- Echogenicity is a significant US feature influencing malignancy assessment.
Purpose of the Study:
- To stratify the malignancy risk of thyroid nodules based on ultrasound (US) features.
- To emphasize the role of nodule echogenicity in malignancy risk assessment.
- To develop a practical categorization system for thyroid nodules.
Main Methods:
- Analysis of 1,058 thyroid nodules from 824 patients (236 malignant, 822 benign).
- Stratification of malignancy risk into four tiers based on US features, particularly echogenicity.
- Multivariate analysis to identify predictive US features for benign and malignant nodules.
Main Results:
- Isoechogenicity, indistinct margins, non-solid content, and parallel orientation predicted benign nodules.
- Hypoechogenicity, spiculated margins, solid content, nonparallel orientation, and calcifications predicted malignancy.
- A four-tier system (benign, probably benign, indeterminate, suspicion of malignancy) was established based on risk percentages.
Conclusions:
- The developed US-based four-tier categorization system is valuable for predicting malignancy risk.
- This system aids in making informed decisions regarding fine-needle aspiration (FNA) for thyroid nodules.
- Isoechoic nodules without calcification can be classified as probably benign, simplifying management.
