Abstract Background Thyroid nodules are less common in children compared to adults, but have a higher likelihood of malignancy. There are few studies, particularly in the pediatric population, examining the association between how and by whom the nodule is detected and the risk of malignancy. Several adult studies have suggested a high rate of malignancy in incidentally discovered thyroid nodules (1,2). However, this was not similarly seen in pediatric thyroid nodules according to one study (3). As fine needle aspiration (FNA) in pediatric patients may be more labor intensive and diagnostic excision is the recommendation for nodules with indeterminate or potentially malignant cytology, if the detection method can be a predictive measure of malignancy, it may enhance the evaluation of pediatric thyroid nodules. Objective The aim of this study is to determine if there is an association between how and by whom a thyroid nodule is detected and the risk of malignancy in the pediatric population. Study Design and Methodology We retrospectively reviewed the medical records of pediatric patients (≤21 years of age) who had a thyroid nodule with definitive cytologic or pathologic diagnosis from January 2010 to June 2019. Patients were categorized into 3 groups based on how and by whom the nodule was detected: (1) patient or parent, (2) provider, or (3) imaging obtained for non-thyroid indications (incidental). Characteristics that were evaluated included rate of malignancy, size of the nodule, location of the nodule, and size of the cancer (if present). Results A total of 78 patients with concerning thyroid nodules were analyzed. Within the study, the cancer rate was 27% (21/78), which is comparable to the reported malignancy rate of pediatric thyroid nodules in the literature (22-26%) (4), suggesting that our sample population may be representative of the general pediatric thyroid nodule population. In our study, though the absolute numbers were small, there was a higher rate of malignancy in the incidental group (3/5, 60%) compared to the patient/parent (9/34, 26%) and provider (9/39, 23%) groups. The average size of the thyroid nodule was similar in all 3 groups. The strength of this study was the inclusion of only patients with definitive diagnosis of the thyroid nodule and the possibility of the findings being applicable to the general pediatric population. Conclusions In our sample study, incidentally discovered pediatric thyroid nodules had a higher rate of malignancy as compared to those discovered by patients/parents or providers. References 1.

BACKGROUND Thyroid cancer has the most rapidly increasing incidence of all major cancers in India. The overall prevalence of thyroid malignancy is approximately 1 - 5 % of all cancers in women and less than 2 % in men. Thyroid nodules are a common clinical finding and have a reported prevalence of 4 – 7 % in the general population. The vast majority of these nodules are non-neoplastic or benign and the risk of malignancy varies from 5 to 10 %. Fine needle aspiration cytology (FNAC) is an efficient and reliable means for the evaluation of thyroid nodules. A key challenge for clinicians is to choose which thyroid nodule is to be investigated further and treated. Early detection and treatment of malignant thyroid nodules is associated with excellent outcomes. The aim of our study is to compare and correlate between fine needle aspiration cytology and histopathology of resected specimen and to determine the diagnostic accuracy of TBSRTC (The Bethesda System for Reporting Thyroid Cytopathology) in thyroid nodule. METHODS This is a cross sectional validation study conducted in a tertiary care hospital (R.G. Kar Medical College) of Kolkata to find the sensitivity, specificity and diagnostic accuracy of TBSRTC in evaluation of thyroid nodule. RESULTS We have observed that TBSRTC is highly sensitive and specific in stratifying the malignancy risk of thyroid nodule. CONCLUSIONS It aids the clinician to choose the thyroid nodules which require further evaluation and intervention. It also guides the clinician to decide the operability of thyroid nodule. TBSRTC is highly accurate and is highly specific in stratifying the risk of malignancy of thyroid nodule. KEYWORDS TBSRTC, FNAC, Thyroid Nodules, Thyroid Cancer

Functional Autonomy

The rate of nodular goiter in children ranges from 0.05 to 5.1%; in this case, the risk of thyroid cancer in childhood amounts to 3―70% of all cases of thyroid pathology. Therefore, the main issue is the differential diagnosis of a nosological variant of a thyroid nodule, which defines the optimal therapeutic tactics for a particular patient. The risk of malignancy is traditionally believed to be low in the case of decompensated functional autonomy of a thyroid nodule; therefore, the need for fine needle aspiration biopsy (FNAB) followed by cytomorphological analysis of the aspirate is avoided in most cases. The presented clinical case demonstrates papillary cancer in an adolescent with a toxic single nodular goiter. A thyroid ultrasound examination revealed a nodular lesion in the boy. An increase in the thyroid size and thyrotoxicosis manifestation occurred 3 years later. A cytomorphological study identified follicular neoplasia; scintigraphy revealed a hot nodule. Surgical treatment was planned. Antithyroid therapy was prescribed to prepare for surgery. After compensation of thyrotoxicosis, hemithyroidectomy was performed. A histological examination diagnosed papillary thyroid cancer, which required repeated thyroidectomy followed by radioiodine I131 ablation. The postoperative period was uneventful; the patient well tolerated suppressive levothyroxine therapy. Therefore, the presence of a toxic single nodular goiter does not exclude thyroid cancer, which defines the need to discuss the indications for FNAB of thyroid nodules in children.

<b><i>Introduction:</i></b> The standard workup of thyroid nodules concerning for malignancy includes fine-needle aspiration (FNA). In 2015, the American Thyroid Association (ATA) guidelines for the management of pediatric thyroid nodules recommended that all nodules with a Bethesda III cytology undergo surgical resection. <b><i>Objectives:</i></b> To correlate a Bethesda III cytology with histologic and clinical outcomes to determine the relevance of the ATA recommendations, and to evaluate whether Thyroid Imaging Reporting and Data System (TI-RADS) scoring could identify Bethesda III nodules at a lower risk of malignancy. <b><i>Methods:</i></b> A retrospective chart review of patients who had undergone thyroid nodule FNA from 2008 to 2018 was performed. Malignancy rates were determined for each Bethesda category. The reference standard was histopathology or 2-year follow-up of imaging outcomes for nonoperative cases. Ultrasound exams of Bethesda III nodules were reviewed and TI-RADS scores assigned. <b><i>Results:</i></b> A total of 143 FNA samples from 128 patients were identified. The mean age was 14.9 years (range 7–22). Twenty-two (15%) of the FNA samples were Bethesda III; the malignancy rate was 38%. A TI-RADS score was assigned in 20 of the 22 Bethesda III nodules. ROC analysis found an optimal cut-off for malignancy prediction of ≥7 points (risk category TR5). The negative predictive value was 85.7% (95% CI 35.9–99.6) and the positive predictive value was 83.3% (95% CI 57.2–98.2). <b><i>Conclusion:</i></b> Although, at baseline, thyroid nodules with a Bethesda III classification carry a moderate risk of malignancy in the pediatric population, TI-RADS scoring can identify nodules with a lower risk within this group. If validated by larger studies, this can inform decision making and reduce unneeded surgery.

Risk Of Malignancy

Thyroid nodules are less frequent in children than adults. Childhood thyroid nodules carry specific features, including a higher risk of malignancy than nodules in adults, rendering them unique in terms of management. Subsequently, they should be considered a distinct clinical entity with specific imaging recommendations. Initial evaluation requires a thorough workup, including clinical examination, and a detailed personal and familial history to determine the presence of possible risk factors. Laboratory and radiologic evaluation play an integral part in the diagnostic algorithm, with ultrasonography (US) being the first diagnostic test in all patients. US elastography has been recently introduced as an incremental method, reducing the subjectivity of the clinical diagnosis of nodule firmness associated with increased malignancy risk. However, fine-needle aspiration biopsy (FNAB) remains the mainstay in the diagnostic work-up of thyroid nodules and is documented to be best method for differentiating benign from malignant thyroid nodules. In addition, thyroid scintigraphy provides functional imaging information, which has a role both in the diagnostic management of thyroid nodules and during follow up in malignancies. Finally, despite providing additional information in certain clinical scenarios, 18F-fludeoxyglucose Positron Emission Tomography (18F-FDG-PET), computed tomography (CT), and magnetic resonance imaging (MRI) imaging are not routinely recommended for the evaluation of patients with newly detected thyroid nodules or in all cases of thyroid cancer. The objective of this review is to summarize the concepts in imaging and imaging-based management of nodular thyroid disease in the pediatric population, acknowledging the unique features that this patient group carries and the specific approach it requires.

Rule Out

Background: Thyroid nodules are commonly present in adult population but are rare in pediatric age group. Inspite of being rare, thyroid nodule have a higher chance of malignancy in children. Thus, pediatric patients presenting with thyroid nodule found clinically or incidentally should be worked up to rule out any possibility of malignancy. The besthesda system for reporting thyroid cytopathology (TBSRTC) is widely used for reporting in adults. The present study aims to use TBSRTC for pediatric thyroid lesions reporting.Methods: All pediatric patients with age ≤ 18 years presenting with thyroid nodule during January 2018 to April 2019 were included in the study, fine needle aspiration (FNA) was done and findings were compared with histology. Statistical analysis was done using SPSS version 18.Results: 42 pediatric patient were included in the study, out of which 2.38% were malignant and suspicious for nmalignant each and 83% were benign.Conclusion: TBSRTC is quite sensitive and specific reporting guideline in pediatric population as in adult population with 100% accuracy in diagnosing benign and malignant cases. This is useful for avoiding unnecessary surgeries.

Thyroid Fna

BackgroundFine needle aspiration (FNA) cytology is the method of choice to exclude malignancy in thyroid nodules. A major limitation of thyroid FNA is the relatively high rate (13–17%) of non-diagnostic samples. The aim of this study is to determine the diagnostic yield of a screw needle compared to the conventional FNA.MethodsWe retrospectively analysed thyroid nodule cytology of all patients that underwent thyroid nodule fine needle or screw needle aspiration between July 2007 and July 2012 in a single academic medical centre. Cytology results were categorized according to the Bethesda classification system.ResultsIn total, 644 punctures of thyroid nodules from 459 patients were available for analysis. The screw needle was used 531 times, and the conventional fine needle 113 times. The percentage of non-diagnostic cytology was significantly lower in the screw needle samples than in the fine needle samples (3% vs 17%, P<0.001).ConclusionThis study shows a significantly better diagnostic performance of the screw needle compared to the conventional fine needle in cytology of thyroid nodules.

Needle Aspiration Cytology

Ultrasonography-guided fine-needle aspiration biopsy is the common choice for diagnosis of the suspected thyroid nodule. An algorithm(s) that finds the malignant potential of a nodule preoperatively, to overcome unnecessary diagnostic methods, does not exist. The objective of the study was to correlate thyroid nodule sizes measured by ultrasonography and risk of malignancy assessed by cytologic and histologic examinations. Data regarding fine-needle aspiration cytology and the results of histologic examinations of surgical specimens of 260 nodules were collected and analyzed. The macro or multiple calcifications, the complex echo pattern, and posterior region homogeneity were considered suspicious in ultrasonography. Bethesda system for classification of thyroid nodules was used for cytopathology. Histopathology performed as per the 2004 World Health Organization classification system. The benefit score analysis was performed for determination of clinical usefulness. Twenty-eight of 49 malignant nodules and 46 of 68 malignant nodules detected through ultrasound following fine-needle aspiration cytopathology and histopathology were <2 cm in size. A correlation was found for malignancy rate detected by ultrasonography-guided fine-needle aspiration cytology and those of the surgical specimen ( r = 0.945, P = .015, R 2 = 0.894). Ultrasonography-guided fine-needle aspiration cytology had 0.994 sensitivities, 0.721 accuracies, and 0.08 to 0.945 diagnostic confidence for the detection of malignant nodules. Nodule size less than 2 mm ( P = .011) was associated with the malignancy potential of thyroid nodules. Ultrasonography-guided fine-needle aspiration cytology had 19 (7%) results as a false negative and 1 (1%) results were false positive. Ultrasound-guided fine-needle aspiration cytopathology reported oversize of thyroid nodule than original but can predict the risk of malignancy. Level of Evidence: III.

AbstractIn children the percentage of “Atypia of undetermined significance/follicular lesion of undetermined significance” (“AUS/FLUS”) cases is greater and the risk of malignancy is higher than expected. Our study aimed to determine if cytologically atypical nodules can be better characterized using imaging techniques for appropriate management of pediatric patients.Thyroid fine needle aspiration (FNA) specimens were reclassified using the Bethesda System for Reporting Thyroid Cytopathology (BSRTC). Cytologic-histologic correlation was performed to determine if the cytopathologic groups had different associations with the surgical outcome. The “AUS/FLUS” lesions were then subdivided based on radiologic features and the outcome was analyzed for each subgroup.Histologically benign follicular nodules showed uniform distribution between the “benign” vs. “AUS/FLUS” (p=0.09) or between the “AUS/FLUS” vs. “follicular neoplasm” (“FN”) cytologic groups (p=0.27). The follicular neoplasms were also evenly distributed between the “FN” vs. “AUS/FLUS” categories (p=0.31). “Benign”, “AUS/FLUS”, and “FN” designations showed comparable associations with papillary thyroid carcinoma classical variant (PTC-cv). Reclassification of atypical lesions based on ultrasound findings yielded two subcategories with different risk of malignancy: one similar to the “benign” group (11% malignancy rate) and one comparable with the “FN” category (28% risk of malignant neoplasm).“AUS/FLUS” designation does not add significant value in categorization of pediatric thyroid nodules. These lesions can be reclassified based on radiologic features to provide accurate information for follow-up.

Abstract Thyroid nodules are common. Evaluation of patients with thyroid nodules typically includes fine needle aspiration biopsy (FNA), an approach that has proven to be accurate for the detection of thyroid cancer. Although the majority of biopsies are adequate for a cytological diagnosis, up to 20% will be insufficient or nondiagnostic. Current opinion suggests that such aspirates should be repeated, although no systematic study has investigated the usefulness of this approach, especially when ultrasound guidance is used to direct the initial FNA. We sought to define the predictors and optimal follow-up strategy for initial nondiagnostic ultrasound-guided FNAs of thyroid nodules. Data were collected for all patients at the Brigham and Women’s Hospital Thyroid Nodule Clinic between 1995–2000 who underwent ultrasound-guided FNA of a thyroid nodule. All patients with nondiagnostic cytology were advised to return for a repeat ultrasound-guided FNA. Patient age, gender, nodule size, cystic content, solitary vs. multinodular thyroid, and nodule location were documented and evaluated as possible predictors of a nondiagnostic biopsy in a multivariable model. The rate of diagnostic cytology obtained on repeat ultrasound-guided FNA was calculated. A total of 1128 patients with 1458 nodules were biopsied over a 6-yr period. A total of 1269 aspirations (950 patients) were diagnostic, and 189 (178 patients) were nondiagnostic. The cystic content of each nodule was the only significant independent predictor of nondiagnostic cytology (P &lt; 0.001). The fraction of specimens with initial nondiagnostic cytology increased with greater cystic content (P &lt; 0.001 for trend). A diagnostic ultrasound-guided FNA was obtained on the first repeat biopsy in 63% of nodules and was inversely related to increasing cystic content of each nodule (P = 0.03). One hundred and nineteen patients with 127 nodules returned for follow-up as advised, and malignancy was documented in 5%. Despite ultrasound-guided FNA, there remains a significant risk of initial nondiagnostic cytology, largely predicted by the cystic content of each nodule. Repeat aspiration is often successful and should be the standard approach to such nodules, given their risk of malignancy.

Background: Several authors have questioned the accuracy of fine- needle aspiration cytology (FNAC) in large thyroid nodules. It's the current practice to provide thyroidectomy to patient with thyroid nodules 4 cm or larger regardless of the FNAC results. The aim of the study is to answer two questions: is the size of nodule associated with higher risk of malignancy and is the size indication for surgery.Methods: Authors conducted a retrospective review of 201 patients who underwent thyroidectomy between 2011 and 2017 at Bahrain defense force hospital. Authors compared all thyroid nodules with benign FNAC and their final histopathology reports. Patients were divided into two groups based on the size of the nodule (< 4cm or >4cm) and indication of surgery.Results: 201 patients with thyroid nodule underwent thyroid surgery. 136 patients had nodule <4cm and 65 patients were ≥4 cm. For patients with nodules <4 cm, 37 patients (18.4%) had a malignancy, and for those with nodules ≥4 cm, 13 patients (6.4%) had a malignancy. comparison between size of the nodule, FNAC result and final histopathology: FNAC diagnosed 55 cases (27.3%) are malignant, final histopathology reported only 50 cases are malignant. But for benign cases FNAC and histopathology reports are showing same results, (p<0.05).Conclusions: Thyroid nodules ≥4 cm are not risk factor of malignancy. Thyroid nodules ≥4 cm with benign FNAC should not undergo thyroidectomy as false negative rate is low. Therefore, the decision for surgery ought not to be taken based on the size of the nodule.
