Diagnostic efficacy of ultrasound combined with fine-needle aspiration biopsy for papillary thyroid carcinoma based on C-TIRADS and ATA guidelines
Clinical Report: Evaluating the Diagnostic Performance of Ultrasound and FNAB
Overview
This study evaluates the diagnostic efficacy of color Doppler ultrasound combined with ultrasound-guided fine-needle aspiration biopsy (US-FNAB) for papillary thyroid carcinoma (PTC). Findings indicate that the combination of these methods provides higher sensitivity and accuracy compared to either method alone, with C-TIRADS demonstrating superior performance over ATA guidelines.
Background
Papillary thyroid carcinoma (PTC) is the most prevalent endocrine malignancy in adults, and accurate diagnosis is crucial for effective management. The integration of ultrasound and fine-needle aspiration biopsy (FNAB) is standard in assessing thyroid nodules, yet variability in diagnostic performance exists. Understanding the comparative effectiveness of risk stratification systems like C-TIRADS and ATA is essential for optimizing clinical outcomes.
Unclear border, irregular shape, vertical growth, microcalcification, aspect ratio >1, capsular invasion, and lobulated lesions are independent risk factors for PTC.
Combined ultrasound and US-FNAB diagnostics achieved higher sensitivity and accuracy than either method alone.
The AUC for the combined diagnostic approach was 0.762, indicating strong discriminative power.
C-TIRADS showed significantly higher sensitivity, specificity, and accuracy compared to ATA guidelines (p<0.05).
Inter-observer agreement for C-TIRADS and ATA classification was good (κ=0.81 and κ=0.77, respectively).
Clinical Implications
The findings support the use of C-TIRADS for routine risk stratification in patients with thyroid nodules prior to FNAB, particularly in Chinese clinical settings. Clinicians should consider the combination of ultrasound and US-FNAB for improved diagnostic accuracy in cases of indeterminate or discordant results.
Conclusion
Ultrasound combined with US-FNAB significantly enhances the diagnostic performance for papillary thyroid carcinoma. The study advocates for the adoption of C-TIRADS in clinical practice to optimize patient management.
