Current Perspectives on Thyroid Nodule Evaluation: Integrating Cytomorphology, Ultrasound Risk Stratification, and...

Area of Science:

• Cytopathology
• Endocrinology
• Oncology

Background:

• Thyroid fine-needle aspiration biopsy (FNAB) is a key diagnostic tool for thyroid nodules.
• Recent advancements have significantly transformed its role in clinical practice.

Purpose of the Study:

• To review the current status and evolving role of thyroid FNAB.
• To highlight the integration of new technologies and classifications in thyroid nodule management.

Main Methods:

• Review of current literature on thyroid FNAB, Bethesda System, WHO classifications, and molecular testing.
• Discussion of integrated diagnostic and management strategies.

Main Results:

• Thyroid FNAB has shifted from a morphologic screening to a precision diagnostic modality.
• Integration of ultrasound, cytopathology, molecular testing, and risk-adapted management is crucial.

Conclusions:

• Thyroid FNAB is now a central component of a multidimensional diagnostic pathway for thyroid nodules.
• Future directions include AI, radiogenomics, active surveillance, and ablation therapies.
