A Tertiary Center's Experience With Second Review of 3885 Thyroid Cytopathology Specimens

Abstract

This is the largest series to date of thyroid cytology second review. The BSRTC classification changed 32% of the time, potentially resulting in significant changes in clinical and surgical management. Because certain specimen characteristics (indeterminate diagnostic category before second review, low specimen cellularity, Hashimoto's thyroiditis, and low volume of consults from the sending institution) were particularly associated with a diagnosis change, morphological second review may be of potential benefit in these settings.
