Rates of Thy 1-non-diagnostic thyroid fine needle aspiration using the UK Royal College of Pathologists Thy Terminology: a systematic review of the literature comparing patients undergoing rapid on-site evaluation and those who do not
Research output: Contribution to journal › Article › peer-review
Methods: A comprehensive literature search of online databases was conducted in October 2019 specifically examining overall reported rates of Thy1 and Thy1c in aspirates classified according to the UK Thy terminology.
Results: Twenty‐five articles were identified showing a Thy1 rate of 13.4% (2540/18 920). The studies were then stratified according to whether or not the patients underwent rapid on‐site evaluation (ROSE): 6.0% (353/5841; range 3.0%‐10.9%) of ROSE aspirates were Thy1 whereas 18.5% (2072/11 204; range 7.9%‐43.3%) of non‐ROSE patients were Thy1; (P < .05). Three studies from 2016 reported Thy1c rates of 5.4%, 6.5% and 10.6%, respectively, implying Thy1 rates excluding Thy1c aspirates of 20.9%, 8.7% and 12.7%, respectively.
Conclusion: This systematic review of the literature shows relatively high rates of aspirates non‐diagnostic for cytological diagnosis‐Thy1 in the peer‐reviewed published literature using the UK terminology. Utilisation of ROSE appears to produce lower rates of Thy1 aspirates and ROSE should be considered if rates of non‐diagnostic for cytological diagnosis‐Thy1/Thy 1c are high.
