Thyroid FNAC cytology: can we do it better?

Area of Science:

• Cytopathology
• Endocrinology
• Surgical Pathology

Background:

• Thyroid nodules are common, but carcinoma is rare.
• Histological assessment is the benchmark, but cytological and histological diagnoses can lack reproducibility.
• Variations exist in criteria for inadequate thyroid FNAC and study parameters.

Purpose of the Study:

• To review recent developments in thyroid fine needle aspiration cytology (FNAC).
• To discuss the implications of in-clinic assessment and reporting.
• To highlight emerging techniques and future directions in thyroid nodule diagnosis.

Main Methods:

• Literature review of recent developments in thyroid FNAC.
• Discussion of conventional versus newer techniques like liquid-based cytology and ultrasound-guided FNAC.
• Analysis of standardized reporting systems and multidisciplinary case reviews.

Main Results:

• In-clinic assessment of specimen adequacy and reporting are increasingly popular but resource-intensive.
• Liquid-based cytology and ultrasound-guided FNAC are gaining traction.
• Standardized categorical systems and multidisciplinary reviews enhance diagnostic clarity and therapeutic guidance.

Conclusions:

• Standardized FNAC reporting systems and multidisciplinary case reviews are crucial for managing thyroid nodules.
• While conventional methods persist, newer techniques offer potential improvements.
• Molecular pathology holds future promise for improving diagnostic accuracy in thyroid FNAC.
