Change in Diagnostic Criteria for Noninvasive Follicular Thyroid Neoplasm With Papillarylike Nuclear Features

Abstract

A study from the international multidisciplinary group, published in April 2016, proposed reclassification of a type of lowrisk thyroid cancer as noninvasive follicular thyroid neoplasm with papillarylike nuclear features (NIFTP), eliminating the term cancer from the tumor name. 1 Since then, the new term has been recommended for use by many professional societies and included as a new thyroid tumor entity in WHO Classification of Tumours of Endocrine Organs from the World Health Organization published in 2017. Over the course of 18 months, more than 80 peer-reviewed publications have reported institutional experience with NIFTP.
