Recent Advances in Core Needle Biopsy for Thyroid Nodules

Area of Science:

• Endocrinology
• Radiology
• Pathology

Background:

• Core needle biopsy (CNB) is an evolving diagnostic tool for thyroid nodules, often replacing fine-needle aspiration (FNA).
• CNB allows for histologic examination, immunohistochemistry, and molecular testing, enhancing diagnostic accuracy compared to FNA.
• While effective, CNB requires experienced operators due to larger needle caliber than FNA.

Purpose of the Study:

• To review current consensus and recommendations for thyroid CNB.
• To focus on indications, potential complications, and standardized pathology reporting for thyroid CNB.

Main Methods:

• Review of recent evidence and guidelines on thyroid CNB.
• Analysis of indications, complications, and pathology reporting systems.
• Incorporation of consensus statements from expert groups.

Main Results:

• CNB provides definitive diagnoses in most thyroid nodule cases.
• Histologic examination with CNB allows for more comprehensive assessment than FNA.
• Guidelines and consensus statements exist for thyroid CNB technique and reporting.

Conclusions:

• Thyroid CNB is a valuable preoperative assessment tool with advantages in histologic detail.
• Standardized guidelines and expert performance are essential for optimal outcomes and complication avoidance.
• Ongoing advancements in technique and devices continue to refine thyroid CNB utility.
