The Ultracyt Study - is EU-TIRADS Useful in Selecting Nodules for Fine Needle Aspiration Cytology?
Selective Ultrasound Guided Cytology Using EU-TIRADS Versus Non-selective Ultrasound Guided Cytology for Diagnosing Thyroid Cancer
Source: ClinicalTrials.gov · Last updated 1 Apr 2025
Brief summary (registry, in English)
This is a randomized study evaluating selective fine-needle aspiration cytology based on structured ultrasound using EU-TIRADS versus non-selective ultrasound guided cytology. Primary outcome is frequency of suspicious cytology (Bethesda III-VI) which is expected to be higher in the selective group compared to the non-selective group. Secondary outcome is the frequency of malignancy which is expected to be equal in both groups. However, the investigators do not expect to reach statistical significance for the secondary outcome according to power calculations.
