Workup and Management of Thyroid Nodules.

Area of Science:

• Endocrinology
• Oncology
• Radiology

Background:

• Thyroid nodules are prevalent, yet most are benign.
• Accurate risk stratification is crucial for appropriate management.
• Overdiagnosis and overtreatment of thyroid nodules are concerns.

Purpose of the Study:

• To outline the diagnostic and management pathway for thyroid nodules.
• To emphasize the role of ultrasound and fine needle aspiration (FNA) biopsy.
• To highlight the importance of the Bethesda system and molecular testing.

Main Methods:

• Utilizing ultrasound (US) for nodule evaluation.
• Performing fine needle aspiration (FNA) biopsy based on US findings and risk stratification.
• Classifying FNA results using the Bethesda System for Thyroid Cytopathology.
• Considering molecular testing when it impacts therapeutic decisions.

Main Results:

• Ultrasound is effective in identifying nodules requiring FNA.
• The Bethesda system provides standardized classification of FNA results.
• Molecular testing can refine risk assessment and guide treatment.
• Patient values are essential in the clinical decision-making process.

Conclusions:

• A systematic approach using ultrasound and FNA, guided by the Bethesda system, is key for thyroid nodule management.
• Molecular testing offers additional value in select cases.
• Balancing diagnostic accuracy with the avoidance of overtreatment, while incorporating patient preferences, is paramount.
