Diagnostic value of puncture feeling combined with BRAF V600E mutation in repeat US-FNA biopsy of Bethesda III thyroid nodules
Abstract
Background: The diagnosis and treatment of Bethesda III thyroid nodules has always been controversial. Our aim is to study the value of puncture feeling combined with BRAF V600E mutation detection in the diagnosis of Bethesda III thyroid nodules in repeat fine needle aspiration (FNA).
Methods: From January 1, 2017 to December 31, 2021, a total of 1,114 thyroid nodules were included, of which Bethesda III thyroid nodules accounted for 12.1%. We analyzed the correlation between puncture feeling and postoperative pathology. Then, the diagnostic value of puncture feeling in Bethesda III thyroid nodules and the mutation rate of BRAF V600E in repeated FNA and its correlation with puncture feeling were analyzed.
Results: The results showed that there was a significant correlation between puncture feeling and postoperative pathology in the 1114 thyroid nodules (P<0.001). Additionally, 93.4% (299/320) of the thyroid nodules with soft puncture feeling were benign, 89.0% (460/517) of the thyroid nodules with hard puncture feeling were malignant, and 93.1% (258/277) of the thyroid nodules with a puncture feeling of hard with grittiness were malignant. There was high consistency of puncture feelings among different operators (P<0.001). The distribution of puncture feeling between benign and malignant thyroid nodules was significantly different (P<0.001) in Bethesda III thyroid nodules. In the puncture feeling ROC curve of Bethesda III thyroid nodules based on pathology, the AUC was 0.895 (95% CI: 0.817-0.973, P<0.001). In repeat FNA, BRAF V600E was significantly correlated with puncture feeling (P<0.001). BRAF V600E mutation was found in 22 (68.8%) malignant nodules.
Conclusions: Puncture feelings of hard and hard with grittiness were malignant risk factors. Repeated FNA and BRAF V600 mutation detection should be performed for Bethesda III thyroid nodules with a hard or hard with grittiness puncture feeling.
