Abstract Introduction/Objective Thyroid cancer is one of the most common prevailing conditions. Both genetic and environmental risk factors play a role in causation of thyroid cancers, with agent orange being the most documented risk factor in Veteran patient population. Based on the ultrasonographic appearance, thyroid nodules can be further investigated by minimally invasive fine needle cytology. This can be done by either of two available techniques, Fine needle aspiration with suction (FNA-S) and Fine needle capillary cytology without using suction (FNC), depending upon the preference of practicing endocrinologist. We aim to compare both cytology techniques for comparing the diagnostic yield and rate of atypia of undetermined significance (AUS) or Follicular lesion of undetermined significance (FLUS), requiring repeat FNA in approximately three months. Methods Retrospective study was conducted by searching the cases performed by an endocrinologist at Corporal Michael J Crescenz VA Medical Center between the period of January 1, 2015 and July 2, 2015. 30 nodules from 11 patients were tested by Fine needle capillary cytology technique (FNC). Yield for the diagnosis with rates of atypical (AUS) cytology were compared. On second set of the 29 patients with 38 nodules, both techniques - FNA-S versus FNC were carried out. Adequacy and rate of AUS/FLUS were calculated. Results Out of 30 total nodules performed by fine needle aspiration (FNA-S), all cases yielded diagnostic material. Of them, 14 (46.6%) were diagnosed as AUS and 16 (53.33%) were benign. On the follow-up/re-aspiration by FNC technique, all these 14 nodules were diagnosed benign. On second set of patients on whom both techniques (FNA-S and FNC) were used alternatively, 13 of 38 nodules (34.21%) were diagnosed as AUS/FLUS, 23 (60.52%) were benign/nodular goiter and 2 were non-diagnostic/inadequate (5.2%). Conclusion FNA-S (with suction) yields adequate diagnostic material, however, also has greater number of atypical cytology results requiring repeat patient visit which may increase morbidity with a burden on total health care cost. FNC (without suction) has low rates of AUS/FLUS, is diagnostically superior with excellent smear quality, less blood clots, time savings, and less inconvenience of patients/physician. FNC (without suction) is a modality of choice for an effective screening of thyroid nodules in veterans.

Introduction: The fine-needle aspiration has a significant role in assessing the malignancy risk of thyroid nodules. There is uncertainty regarding the value of repeat fine-needle aspiration in benign nodules. This study aims to evaluate the concordance of results in consecutive fine-needle aspiration and to study the relevance of repetition in benign results.Material and Methods: Retrospective study of the 4800 thyroid nodules fine-needle aspiration held in Instituto de Patologia e Imunologia Molecular da Universidade do Porto between January 1, 2014 and May 2, 2016. Of the initial sample, we selected the repeated fine-needle aspiration on the same nodule.Results: The first fine-needle aspiration result of the 309 nodules underwent revaluation was non-diagnostic in 103 (33.3%), benign in 120 (38.8%) and atypia/follicular lesion of undetermined significance in 86 (27.8%). The agreement between the first and second fine-needle aspiration was significantly higher in cases with an initial benign result (benign: 85.8%, non-diagnostic: 27.2% and atypia/ follicular lesion of undetermined significance: 17.4%, p < 0.005). The fine-needle aspiration repeating motifs in initially benign nodules (n = 78) were repetition suggestion in 58, nodule growth in 17 and suspicious ultrasonographic features in 3.Discussion: The fine-needle aspiration repetition in nodules with initial non-diagnostic and atypia/follicular lesion of undetermined significance result changed the initial diagnosis in a significant proportion of patients, modifying their therapeutic approach. The high concordance of results in initially benign nodules makes fine-needle aspiration repetition not cost-effective in most cases.Conclusion: The fine-needle aspiration should be repeated when the initial cytology result is non-diagnostic or atypia/follicular lesion of undetermined significance.

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.

Nodular goiter is a rare condition in children and adolescents and compared with adults, thyroid nodules are more frequent malignant in pediatric population. We have investigated the prevalence of thyroid carcinoma among the thyroid disorder emphasizing on the surgical treatment in term of indication, methods and complications. Retrospective study of 35 children and adolescents with nodular goiter. Demographic data, thyroid ultrasonographic features, fine needle biopsy aspiration, hormonal profile, surgical treatment procedure as well as histological aspects were recorded. Study included 26 (74%) girls and 9 (26%) boys with a mean age of 11.66 years. Fine needle aspiration biopsy was performed in 10 cases due to the TIRADS score � 4 with Bethesda II in 3 cases, Bethesda III in 4 cases and Bethesda V in 3 cases. The surgical treatment was performed in 16 (45.7%) cases due to fine needle aspiration biopsy results or due to the relapse after medical treatment. Lobectomy was performed in 7 (43.7%) cases while total thyroidectomy was the final option for the rest of 9 (56.3%) patients. As a result of pathological examination in 8 cases the thyroid carcinoma has been found. The rest of 8 patients presented benign thyroid findings (follicular adenoma, toxic adenoma and Graves� disease with follicular adenoma). The prevalence of thyroid carcinoma among the pediatric population with thyroid nodules was 22.8% most affected being the female gender.

Purpose: The purpose of this study was to evaluate the predictive value of ultrasonography (US) patterns based on the 2015 American Thyroid Association (ATA) guidelines for malignancy in atypia of undetermined significance or follicular lesion of undetermined significance (AUS/FLUS) nodules. Methods: From January 2014 to August 2015, 133 thyroid nodules that were initially diagnosed as AUS/FLUS on fine needle aspiration (FNA) were included in this study. Each nodule was assigned a category with US patterns defined by the ATA guidelines. Clinical characteristics and US patterns were compared between the benign and malignant nodules, and malignancy rates were calculated according to the ATA guidelines. Results: The malignancy rate in the very low suspicion group was 0.0% in AUS/FLUS nodules. When applying the ATA guidelines, significant differences existed for US patterns between the benign and malignant nodules in the AUS group ( P = .032) but not the FLUS group ( P = .168). Conclusions: Ultrasonography patterns by the 2015 ATA guidelines can provide risk stratification for nodules with AUS cytology but not for ones with FLUS cytology. For nodules with AUS/FLUS cytology with the very low suspicion pattern of the ATA guidelines, follow-up US might be recommended instead of repeat FNA.
