Atypia of undetermined significance/follicular lesion of undetermined significance (AUS/FLUS) in thyroid fine needle aspiration (FNA) is a challenging category. The malignancy risk is different by multiple factors and subsequent management strategy is inconclusive. Therefore, we analyzed the malignancy risk of AUS/FLUS according to radiological and clinical features. A total of 687 nodules that had been initially diagnosed as AUS/FLUS were retrospectively reviewed from 6365 thyroid FNAs between 2011 and 2014. The ultrasonographic (US) features were categorized using the Korean Thyroid Imaging Reporting and Data System. Radiological and clinical features were compared according to the second FNA results or histologically confirmed results from surgery. Repeat FNA was performed on 248 (36%) nodules, and 49 (7%) nodules underwent immediate surgery. Among the 248 nodules subjected to repeated FNA, 49 (20%) nodules were diagnosed again as AUS/FLUS, 123 (50%) were found to be benign, and 47 (19%) were diagnosed as follicular neoplasm, suspicious for malignancy or malignant. Among histologically confirmed nodules, the US features were more unfavorable in malignant nodules, and hypo- or anechogenicity was associated with a higher risk of malignancy after adjusting for age, size, and other US features (P<0.01). In conclusion, we observed that malignant nodules tended to show unfavorable US features, especially hypo- or anechogenicity. Age, sex, and thyroid function were not significantly associated with malignancy risk. We also found out that malignancy risk was not different between the group which underwent immediate operation following the AUS/FLUS diagnosis and the group which underwent repeated FNA after the initial diagnosis.

Context.—Fine-needle aspiration (FNA) biopsies have been an important component in the preoperative evaluation of thyroid nodules. Until the introduction of the Bethesda System for Reporting Thyroid Cytopathology (BSRTC) in 2008, individual institutions had developed their own diagnostic categories. The BSRTC proposed 6 categories in an attempt to standardize reporting of thyroid FNA. Objective.—To present a 15-year experience of thyroid FNA at one institution, including data before and after introduction of the BSRTC. The risk of malignancy is compared with the meta-analysis of high-quality published data. Data Sources.—Data sources were PubMed, a manual search of references, and institutional data. Conclusions.—The diagnostic categories developed at our institution were similar to those proposed by the BSRTC, with best fit into the 6 categories easily accomplished and reported in the final 2 years of the study. Significant differences were noted in the frequencies of cases in diagnostic categories Benign (II; P = .003), Suspicious for follicular neoplasm/Follicular neoplasm (IV; P &lt; .001), and Malignant (VI; P = .003) after the introduction of the BSRTC. Eighteen published articles met the criteria for inclusion in the meta-analysis. The risk of malignancy in each category in our institution was similar to that determined in the meta-analysis, except for Insufficient for diagnosis (I; 20% versus 9%–14%). Meta-analysis showed an overlapping 95% CI of risk of malignancy between Atypia of undetermined significance/Follicular lesion of undetermined significance (III; 11%–23%) and Suspicious for follicular neoplasm/Follicular neoplasm (IV; 20%–29%), suggesting similar risks of malignancy. The use of newer molecular tests for these indeterminate cases may further refine risk assessment.

Introduction: Approximately 10% of fine needle aspiration biopsy (FNAB) of thyroid nodules may be verified as “suspicious for follicular neoplasm”; this category involves follicular adenoma, follicular carcinoma, follicular variants of papillary carcinoma and subclass “suspicious for Hurthle cell neoplasm”. At present, there is no diagnostic tool to discriminate between follicular adenoma and cancer. Most patients are required surgery to exclude malignant process. The aim: To define factors correlating with risk of malignancy in patients with FNAB of thyroid focal lesions and nodules verified as Bethesda tier IV. Materials and Methods: In this study 110 consecutive patients were included. All patients were operated because of FNAB result “suspicious for follicular neoplasm” of thyroid gland at a single institution from January 2016 until March 2020. From this set, six specific categories were defined and the clinical records for patients were collected: sex, age, presence of oxyphilic cells, diameter of the tumour, presence of Hashimoto disease, aggregate amount of clinical and ultrasonographic features of malignancy according to ATA. Results: In 18 patients (16,3%) thyroid cancer occurred. Most frequent subtype turned out to be papillary cancer (66,6%). In group of benign lesion (92 patients) predominance of follicular adenoma was disclosed – (49%). Age, gender, tumour diameter, aggregate amount of clinical and ultrasonografic factors, presence of Hashimoto disease and fine needle aspiration biopsy result suspicious for Hurthle cell neoplasm did not correspond to increased risk of malignancy. Conclusions: In patients with FNAB results classified as Bethesda tier IV there are no reliable clinical features associated with low risk of malignancy and surgery should be consider in every case as most appropriate manner to exclude thyroid cancer

ABSTRACT Aim To correlate selected clinical and ultrasonographic (US) characteristics with the final histopathological diagnosis in patients with atypia of undetermined significance (AUS) and follicular lesion of undetermined significance (FLUS), and whether this information can be used in planning the surgical approach. Materials and methods It is a retrospective study including the operated cases of AUS/FLUS from 2011 to 2014 treated at one center. Results This cohort included 87 women and 28 men. To test for independence between categorical variables, the chi-square test was used. There was no significant correlation between age or US variables and final pathological diagnosis. However, final diagnosis of malignancy was higher in men compared with women (64.3 and 41.4% respectively; p = 0.035). Furthermore, a significant association between the diagnosis of repeated fine needle aspiration biopsy (FNAB) and the final pathological diagnosis was noted (benign vs malignant, p = 0.005). Conclusion The FNAB has a significant role in the assessment of thyroid nodules. Our results showed no correlation between age, US variables, and the risk of malignancy. Male gender is associated with higher risk of malignancy. Clinical significance Determining the risk of malignancy and prediction of surgical outcome may help triaging cases for repeat FNA or proceeding to surgery.

Background: Fine-needle aspiration cytology (FNAC) is recommended as a decisive diagnostic step in the workup of patients with nodular thyroid disease. Unfortunately, FNAC can miss malignancies in smaller and deeper nodule. Ultrasound guided FNAC (US-FNAC) can reduce this error in suspicious thyroid nodule. Objectives: To find out the correlation of USG guided FNAC with postoperative histopathology in diagnosis of thyroid nodule. Methods: After obtaining clearance and approval from Institutional Review Board, all 45 patients of thyroid nodule who were admitted in the Department of Otolaryngology – Head & Neck surgery of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka from April 2017 to August 2018 and had fulfilled the inclusion and exclusion criteria were selected for the study. Each patient was assessed before surgery by USG guided FNAC and post operatively by histopathology. Results: In this study mean age of the respondents was 33.33 yearswith SD±10.84. Male female ration was 1:5.4. USG guided FNAC was reported by ‘The Bethesda System for Reporting Thyroid Cytopathology’ (TBS-RTC).Of the 45 specimens 2 samples were nondiagnostic or unsatisfactory (Class I), 26 samples were benign (Class II), 2 samples were showing Atypia of Undetermined Significance or Follicular lesion of Undetermined Significance (Class III), 6 were showing follicular neoplasm or suspicious for a follicular neoplasm (Class IV), 5 samples were suspicious for malignancy (Class V) and 4 samples were positive for malignancy (Class VI). On comparison of ultrasound guided FNAC with histopathology the sensitivity for correct diagnosis was 94%, specificity was 93%, positive predictive value was 88%, negative predictive value was 96% and accuracy was 93%. Pearson’s correlation coefficient was 0.85 which is very strong for positive relationship. Conclusion: USG guided FNAC is the most accurate method for diagnostic evaluation of thyroid nodules.
