Utility of fine‐needle aspiration for diagnosis of carcinoma associated with multinodular goitre

Abstract

Thyroid fine needle aspiration is not useful for differentiating MNG with malignant degeneration from benign MNG, as more than 80% of carcinomas go unnoticed; it provides a sensitivity of 17% for detecting carcinomas, rising to 26% if microcarcinomas are excluded. We therefore suggest that clinical criteria should prevail over FNA.
