Abstract
OBJECTIVE To analyze the detection rate of thyroid nodules and its influencing factors among individuals undergoing routine health check-up in Guangdong Province. METHODS We analyzed the results of thyroid ultrasonography of 309 576 individuals receiving routine health check-up in a general hospital in Guangdong Province over the past 10 years. The data were compared between the individuals with and without thyroid nodules using two independent samples t test, MannWhitney U test and Chi-square test. Binary logistic regression was used to analyze the relationship between different factors and thyroid nodules, and the odds ratio (OR) and 95% confidence interval (95% CI) were calculated. RESULTS Based on the structured and standardized data, the total detection rate of thyroid nodules was 9.68% among the individuals, 7.71% in male and 13.51% in female subjects, showing a significant gender difference (χ2=2677.08, P < 0.001). In the overall population, the detection rates of thyroid nodules gradually increased with age, but in each age group, the detection rate remained significantly higher in female subjects than in male subjects (P < 0.001). The subjects with thyroid nodules showed a significant higher percentage of male gender, an older age, a greater BMI, and significantly higher SBP, DBP, FBG, TC, LDL-C, HDL-C, TG as well as higher detection rates of fatty liver, hyperlipidemia, hyperglycemia, and metabolic syndrome than those without thyroid nodules (all P < 0.001). Binary logistic regression analysis showed that thyroid nodules were significantly associated with gender (OR=0.455, 95%CI: 0.443-0.468), age (45-59 years: OR=1.660, 95%CI: 1.613-1.710; ≥ 60 years: OR=3.329, 95%CI: 3.202- 3.462), BMI (underweight: OR=0.808, 95%CI: 0.755-0.864; overweight: OR=1.074, 95%CI: 1.038-1.112; obesity: OR=1.281, 95%CI: 1.221-1.343), hyperlipidemia (OR=1.053, 95%CI:1.022-1.085), high blood glucose (OR=1.177, 95%CI: 1.105-1.252), and metabolic syndrome (OR=1.111, 95%CI: 1.071-1.152). CONCLUSIONS The detection rate of thyroid nodule is much higher in female than in male individuals in Guangdong Province and is significantly associated with gender, age, BMI and metabolic related diseases. Male gender and underweight might be protective factors for thyroid nodules, while an advanced age, overweight/obesity, hyperlipidemia, high blood glucose and metabolic syndrome are associated with an increased risk of thyroid nodules. Thyroid ultrasound examination is recommended in routine health check-up for early detection and treatment of thyroid diseases.

Abstract
Objective: To investigate the release of progastrin-releasing peptide (ProGRP) in patients with thyroid nodules and the value of ProGRP in fine-needle aspirate washout fluid (FNA-ProGRP) in the differential diagnosis between medullary thyroid carcinoma (MTC) and non-MTC thyroid nodules. Methods: We investigated 2,446 healthy persons and 212 patients with 235 thyroid nodules. They were classified into healthy, nodular goiter, chronic thyroiditis, thyroid follicular neoplasm, papillary thyroid carcinoma, follicular thyroid carcinoma, and medullary thyroid carcinoma. The serum ProGRP and FNA-ProGRP were measured. Results: The serum ProGRP median concentration in MTC was 124.40 pg/mL, significantly higher than in other groups. The cutoff value of serum ProGRP was 68.30 pg/mL, leading to 53.85% sensitivity, 96.98% specificity, and 0.51 kappa value in MTC. The FNA-ProGRP median concentration in MTC nodules was 2,096.00 pg/mL, significantly higher than in other groups. A receiver operating characteristic analysis of MTC nodules and non-MTC nodules indicated that the cutoff value was 22.77 pg/mL, leading to 94.12% sensitivity, 98.27% specificity, and 0.85 kappa value. Conclusion: FNA-ProGRP measurement could be served as an ancillary method for the differential diagnosis between MTC and non-MTC thyroid nodules. Abbreviations: CEA = carcinoembryonic antigen; CT = calcitonin; FNAC = fine-needle aspiration cytology; FNA-CT = calcitonin in fine-needle aspirate washout fluid; FNA-ProGRP = ProGRP in fine-needle aspirate washout fluid; MTC = medullary thyroid carcinoma; ProGRP = progastrin-releasing peptide; SCLC = small-cell lung cancer; TM = tumor marker.

Abstract
Objective: Generally recommended treatment options for cystic nodules with compressive symptoms are simple aspiration, percutaneous ethanol injection, or surgery. N-butyl cyanoacrylate (NBCA) is a glue-like substance widely used in neurointerventions, mainly for treating arteriovenous malformations. It obstructs and attaches to the vessel walls, preventing recanalization. Our purpose was to investigate the efficacy and safety of NBCA in volume reduction of benign cystic thyroid nodules with compressive symptoms. Methods: Twenty patients with 21 benign pure or partially cystic nodules were enrolled. After simple cyst aspiration, NBCA/lipiodol mixture was injected within the cyst cavity. Success was defined as at least 50% volume reduction after the intervention. Pre- and postintervention longest diameter and volume (calculated with ultrasonography after measuring three dimensions) of the nodules were compared. Posttreatment measurements were made at the 9-month final visit. Results: Median largest diameter of the nodules measured before and after NBCA treatment was 4.8 cm (min-max, 3.1 and 6.3 cm) and 3.4 cm (min-max, 2.4 and 5.6 cm), respectively. Pre-NBCA treatment median volume was 24.8 mL (min-max, 10.9 and 46.1 mL), whereas post-treatment median volume was 5.5 mL (min-max, 2.1 and 29.6 mL). Median volume reduction was 72.6% (min-max, 21.0 and 95.4%). Intervention was successful in 20 of 21 nodules according to the predefined criteria. The changes in pre- and postintervention median longest diameter and volume were statistically significant. Conclusion: For large cystic thyroid nodules, ablation with NBCA may be an effective treatment choice, as it significantly reduces the cyst volume and prevents fluid re-accumulation. There is need for further studies with a larger number of patients and longer follow-up. Abbreviations: NBCA = N-butyl cyanoacrylate; PEI = percutaneous ethanol injection; US = ultrasonography.

Abstract
Objective: We assessed our experience with Afirma gene expression classifier (GEC) combined with sono-graphic risk assessment, using both the American Thyroid Association (ATA) and the Thyroid Imaging Reporting and Data System (TI-RADS) in evaluating indeterminate thyroid nodules. Methods: We identified 98 patients with 101 nodules who had a second fine needle aspiration biopsy (FNA) between January 1, 2014, and September 30, 2017, and sent to Veracyte for cytopathology and subsequent Afirma GEC testing. A second FNA biopsy was performed if the initial cytopathology was either Bethesda III or IV (n = 94) or nondiagnostic (n = 7). We correlated cytopathology, histopathology, and Afirma GEC results with sonographic risk assessment using both the ATA system and TI-RADS. Results: The mean age of the cohort was 57.4 ± 12.3 years; 84% women and 60% white. Repeat FNA was benign in 51 of 101 nodules, and of the remaining 50 nodules, 18 (36%) were GEC-benign and 32 (64%) GEC-suspicious. Eighteen of the 32 GEC-suspicious nodules underwent surgery with the following results: 7 benign (39%), 1 follicular thyroid carcinoma (6%), 6 follicular variant of papillary thyroid cancer (33%), and 4 noninvasive follicular tumor with papillary-like nuclear features (22%). The malignancy rate among the surgical cohort was 39% (without noninvasive follicular tumor with papillary-like nuclear features [NIFTP]) and 61% (with NIFTP) and about 50% and 20% of this group scored in the high suspicion category by ATA and TR5 by TI-RADS, respectively. Conclusion: Afirma GEC was useful in avoiding surgery in one-third of indeterminate nodules and performed similarly to ATA and TI-RADS. However, the use of echogenicity in scoring may underestimate the risk of malignancy in patients with indeterminate nodules. Abbreviations: ATA = American Thyroid Association; AUS = Atypia of Undetermined Significance; FLUS = Follicular Lesion of Undetermined Significance; FN = follicular neoplasm; FNA = fine needle aspiration; FTC = follicular thyroid cancer; FVPTC = follicular variant of papillary thyroid cancer; GEC = Gene Expression Classifier; ND = nondiagnostic; NIFTP = noninvasive follicular tumor with papillary-like nuclear features; TI-RADS = Thyroid Imaging Reporting and Data System; TR = TI-RADS.

Abstract
OBJECTIVE 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. PATIENTS AND METHODS 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 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. CONCLUSION 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
OBJECTIVE To summarize and evaluate the value of applying the thyroid imaging reporting and data system (TI-RADS) released by American College of Radiology (ACR) in 2017 of the thyroid classification, and to propose an optimized classification method based on the result to facilitate more accurate and precise risk stratification of thyroid nodules. METHODS In the study, 342 thyroid nodules assessed by 2017 ACR TI-RADS were retrospectively analyzed. Each nodule had a score, and all the scores of nodules were compared with the pathological results. The proportion of malignant nodules in different scoring ranges was obtained. The diagnostic efficacy of all nodules, nodules above 1 cm and less than or equal to 1 cm was evaluated by ROC curve, respectively. RESULTS The AUC of all nodules, nodules above 1 cm and less than or equal to 1 cm were 0.907, 0.936 and 0.717, respectively. With the increase of the scores, the proportion of benign nodules decreased gradually, and the proportion of malignant nodules increased, especially nodules of 4-6 scores increased significantly. Based on the proportion of malignant nodules with 3 scores, the proportion of malignant nodules with 4, 5 and 6 scores increased 1.6, 3.8 and 5.3 times, respectively. The proportion of malignant nodules with 6-8 scores was 81%-84%, while the proportion of malignant nodules with 9 scores or more was 93%-94%. According to the distribution characteristics of malignant nodules, the classification of TI-RADS was adjusted. TI-RADS 4 was divided into TI-RADS 4a, TI-RADS 4b and TI-RADS 4c, corresponding to 4, 5 and 6-8 scores respectively, while the nodules with 9 scores or more were divided into TI-RADS 5. CONCLUSION 2017 ACR TI-RADS has high diagnostic value for thyroid nodules above 1 cm, but it is not so effective for the nodules less than or equal to 1 cm. According to the proportion distribution of malignant nodules in different scoring ranges, appropriate adjustment of classification will be more accurate and precisely predict the malignant risk of nodules.

Abstract
Objective: Acromegaly results from the excessive production of growth hormone and insulin-like growth factor-1. While there is up to a 2-fold increased prevalence of thyroid nodules in patients with acromegaly, the incidence of thyroid cancer in this population varies from 1.6 to 10.6% in several European studies. The goal of our study was to determine the prevalence of thyroid nodules and thyroid cancer among patients with acromegaly at a large urban academic medical center in the United States (U.S.). Methods: A retrospective chart review was performed of all patients with acromegaly between 2006-2015 within the University of California, Los Angeles health system. Data were collected regarding patient demographics, thyroid ultrasounds, thyroid nodule fine needle aspiration (FNA) biopsy cytology, and thyroid surgical pathology. Results: In this cohort (n = 221, 49.3% women, mean age 53.8 ± 15.2 [SD] years, 55.2% Caucasian), 102 patients (46.2%) underwent a thyroid ultrasound, from which 71 patients (52.1% women, mean age 52.9 ± 15.2 [SD] years, 56.3% Caucasian) were found to have a thyroid nodule. Seventeen patients underwent a thyroid nodule FNA biopsy and the results revealed 12 benign biopsies, 1 follicular neoplasm, 3 suspicious for malignancy, and 1 papillary thyroid cancer (PTC), from which 6 underwent thyroidectomy; PTC was confirmed by surgical pathology for all cases (8.5% of all nodules observed). Conclusion: In this sample, the prevalence of thyroid cancer in patients with acromegaly and coexisting thyroid nodules is similar to that reported in the general U.S. population with thyroid nodules (7 to 15%). These findings suggest that there is no benefit of dedicated thyroid nodule screening in patients newly diagnosed with acromegaly. Abbreviations: AACE = American Association of Clinical Endocrinologists; ATA = American Thyroid Association; DTC = differentiated thyroid cancer; FNA = fine needle aspiration; GH = growth hormone; IGF-1 = insulin-like growth factor-1; PTC = papillary thyroid cancer; U.S. = United States.

Abstract
Objective: The recommended treatment options for toxic adenoma (TA) in the USA are radioactive iodine ablation and surgical resection, with continued observation for pre-toxic adenoma (PTA). Percutaneous ethanol ablation (PEI) has proven efficacy in the treatment of TA and is widely available in Europe but not in the USA. Methods: Retrospective analysis was performed of all patients who underwent PEI for TA/PTA at the University of Utah, from January 2010 to 2018. Ultrasound-guided PEI, with injections targeting power Doppler-mapped blood vessels within the adenomas, was conducted. Functionality was confirmed using thyroid scintigraphy prior to PEI. Results: Eighteen adults (15 female) underwent PEI. Mean age was 41 ± 13.7 years. Baseline thyroid-stimulating hormone (TSH) was suppressed (0.06 ± 0.09 mU/L), with normal free thyroxine (FT4) 1.43 ± 0.39 ng/dL. Median nodule volume was 5.7 cm3 (interquartile range [IQR], 4.8 to 7.7 cm3). Seventy-eight percent (n = 14) underwent two or less PEI sessions. Median volume of ethanol used was 0.46 mL/mL nodule volume (IQR, 0.3 to 0.6 mL). There was a significant increase in TSH concentrations within the first 3 months after PEI (0.06 ± 0.09 mU/L vs. 1.22 ± 1.88 mU/L; P = .02), with a concomitant significant decrease in FT4 concentrations (1.43 ± 0.39 ng/day vs. 1.13 ± 0.25 ng/day; P<.01). Significant nodular volume reduction was observed following PEI (median 5.7 cm3 [IQR 4.8-7.7 cm3] vs. 2.5 cm3 [IQR 2.0-7.8 cm3]; P<.01). Conclusion: Vascularity-targeted PEI is safe and effective for treating PTA and TA. This unique approach required lower injected alcohol volume and fewer injections for therapeutic success.

Abstract
Objective: To assess which measure of thyroid nodule growth on serial neck ultrasound, if any, is associated with malignancy. Methods: Retrospective exploratory chart review of malignant thyroid nodules assessed at Kingston Health Sciences Centre (2006-2016) and benign thyroid nodules (2016), at least 1 cm in diameter and with 2 ultrasounds completed at least 30 days apart. Groups were compared using independent samples Student's t test, chi-square test, or Mann-Whitney U test as appropriate, as well as multivariable logistic and linear regression modelling to adjust for age and baseline volume. Results: One hundred and seventy-eight nodules were included in the study. When growth was defined as >20% increase in 2 dimensions (minimum 2 mm), malignant nodules (MNs) underwent significantly more growth than benign nodules (BNs) (16.8% BN versus 29.8% MN [P = .026]; odds ratio = 2.49; 95% confidence interval = 1.12 to 5.56). There was no significant difference between the groups when growth was defined as >2 mm/year or ≥50% volume growth. Nodules shrank >2 mm/year in each group and the difference was not statistically significant (24.2% BN versus 20.7% MN [P = .449]). The median doubling time for the nodules that grew was 1022.1 days in the BN group and 463.2 days in the MN group (P = .036). The median doubling time for all nodules was 456.5 days in the BN group and 244.2 days in the MN group (P = .015). Conclusion: Thyroid nodule growth defined as >20% increase in 2 dimensions (minimum 2 mm) is associated with risk of malignancy. Nodule shrinkage did not distinguish between BNs and MNs.

Abstract
Objective: Thyroid nodules with indeterminate cytology pose management challenges in clinical practice. The aim of this study was to determine the efficacy of ultrasound features in navigating clinical decision making in thyroid nodules with indeterminate cytology. Methods: We retrospectively reviewed ultrasound imaging from 186 adult patients with thyroid nodules and indeterminate cytology who underwent thyroidectomy at a quaternary hospital from 2010-2017. All nodules were classified based on the American Thyroid Association (ATA) and 2017 American College of Radiology Thyroid Imaging Reporting and Data System (ACR TI-RADS). Nodules were included if good quality pre-operative ultrasound imaging and surgical pathology were available. Results: A total of 202 thyroid nodules were included. The median age was 57 years; 82.8% were female. Risk of malignancy (ROM) in resected nodules with Bethesda 3 and 4 cytology was 19.4% and 30.3%, respectively. ATA high-suspicious and TI-RADS 5 nodules had high ROM, 100% in both systems for Bethesda 3 nodules; 66.7% and 50.0%, respectively, for Bethesda 4 nodules. For ATA very-low suspicious/TI-RADS 1 and 2, ROM was 0%. ROM in ATA low-suspicious/TI-RADS 3 nodules with Bethesda 3 cytology was lower (15.2% and 16.0%, respectively) than Bethesda 4 cytology (33.8% and 34.3%, respectively). ATA intermediate-suspicious/TI-RADS 4 nodules with Bethesda 4 cytology had a lower ROM (11.1% and 18.2%, respectively) than Bethesda 3 cytology (28.6 % and 31.6%, respectively). Conclusion: Using either the ATA or the TI-RADS system to risk-stratify nodules with indeterminate cytology may help clinicians plan better for additional diagnostic testing and treatment. Abbreviations: ACR = American College of Radiology; ATA = American Thyroid Association; AUS = atypia of undetermined significance; FLUS = follicular lesion of undetermined significance; FN = follicular neoplasm; PPV = positive predictive value; ROM = risk of malignancy; SFN = suspicious for follicular neoplasm; TI-RADS = Thyroid Imaging Reporting and Data System.
