ABSTRACT. The present study was conducted to analyze the correlation between ultrasonic characteristics, pathological type, and molecular markers of thyroid-tumor-related genes as well as to evaluate the diagnosis and prognosis of thyroid nodules. The acoustic characteristics of 130 thyroid specimens were detected. Pathological sectioning and immunohistochemical detection were performed to determine the correlation between tumor gene expression and ultrasonic characteristics. Ultrasonic testing revealed that malignant nodules were normally accompanied by lymph nodes. Expression of the human telomerase reverse transcriptase, Ki67, vascular endothelial growth factor, Ret, and P53 genes exhibited statistically significant differences in malignant, benign, and normal tissues. The performance of thyroid malignant nodules showed different degrees of correlation with the expression of the human telomerase reverse transcriptase, Ki67, VEGF, Ret, and P53 genes. Color Doppler ultrasound is highly sensitive for thyroid nodules and is therefore

Objective: The Bethesda System for Reporting Thyroid Cytopathology is now widely used as the standard reporting system for fine-needle aspiration cytology (FNAC). Recently, several studies have attempted to subcategorize the atypia of undetermined significance (AUS)/follicular lesion of undetermined significance (FLUS) category. We aimed to analyze the significance of a subcategory of AUS/FLUS showing both cytologic and architectural atypia (AUS/FLUS-C&A). Study Design: From April 2011 to May 2014, 18,091 patients underwent FNAC at Samsung Medical Center. For those patients we analyzed the clinical significance of the subcategory AUS/FLUS-C&A. Results: One hundred and sixty-three patients were diagnosed as AUS/FLUS-C&A. Of 71 cases with subsequent histologic confirmation, 47 (66.2%) were diagnosed with papillary thyroid carcinoma (PTC). Of the 47 PTC cases, 32 (68.1%) were follicular variant-PTC. A significant difference in the PTC rate (58.3 vs. 82.6%) and PTC size (average: 1.8 and 0.9 cm) was noted between circumscribed lesions and infiltrative lesions on ultrasonography. Conclusion: We demonstrated that the subcategory of AUS/FLUS-C&A has considerable clinical implications and one should be aware of the cytological and ultrasonographic features.

Recently, several molecular assays for detecting the BRAF V600E mutation in fine-needle aspiration (FNA) specimens have been developed. Herein, we tested 294 consecutive FNA samples from patients with thyroid nodules with the Real-Q BRAF V600E detection assay (Real-Q). These results were compared with an allele-specific PCR-based kit using dual-priming oligonucleotides (AS-PCR). Any discordant results between the two tests were also analyzed by mutant enrichment with 3'-modified oligonucleotide sequencing. A total of 128 cases were confirmed histologically; of these, 121 were diagnosed as papillary thyroid carcinoma (PTC). The BRAF mutation was detected by Real-Q and AS-PCR testing in 80.2% (95% CI, 71.9%-86.9%) and 76.9% (95% CI, 68.3%-84.0%), respectively, of FNA specimens with PTC. Combining the BRAF V600E molecular assays (Real-Q and AS-PCR) with cytological diagnoses of malignant and suspicious for malignant cells, the detection rates (sensitivity) of Real-Q and AS-PCR for diagnosis of PTC increased to 94.2% (95% CI, 88.4%-97.6%) and 92.6% (95% CI, 86.4%-96.5%), respectively. In conclusion, the detection of BRAF V600E mutations in PTC by Real-Q is compatible to that of AS-PCR.

Clinical Implication of Highly Sensitive Detection of the BRAF V600E Mutation in Fine-Needle Aspirations of Thyroid Nodules: A Comparative Analysis of Three Molecular Assays in 4585 Consecutive Cases in a BRAF V600E Mutation-Prevalent Area

Abstract: Highly sensitive and specific molecular assays such as MEMO sequencing are optimal for detecting the BRAF mutations in thyroid FNAC because these techniques can detect PTC that might be missed by cytology or less sensitive molecular assays.
