Objective. To compare the cytology quality of ultrasound-guided fine-needle biopsy in thyroid nodules with 22-, 23-, and 25-gauge (G) needles prospectively. Methods. A total of 240 consecutive nodules underwent ultrasound-guided fine-needle aspiration (USG-FNA) and 240 nodules underwent ultrasound-guided fine-needle capillary (USG-FNC) were included in this prospective study from October 2014 to February 2016. Each nodule was sampled using 22 G, 23 G, and 25 G needle according to designed orders, and 1240 smears were finally obtained. Cytology quality was scored by a cytologist blinded to needle selection. Results. In USG-FNA, the average scores and standard deviations were 5.50 ± 2.87 for 25 G needles, 4.82 ± 2.95 for 23 G needles, and 5.19 ± 2.81 for 22 G needles. In USG-FNC, the average scores and standard deviations of each group were 5.12 ± 2.69 for 25 G, 4.60 ± 2.90 for 23 G, and 4.90 ± 2.90 for 22 G needles. The specimen quality scores of 25 G group were significantly higher than that of 23 G group ( P < 0.017 ) in both USG-FNA and USG-FNC. However, the differences were not statistically significant in nondiagnostic rate using different gauge of needles ( P > 0.017 for all). Conclusions. 25 G needles obtained the highest scores of sample quality in thyroid FNA and FNC comparing with 22 G and 23 G needles. 25 G needle should be first choice of thyroid FNA and FNC in routine work.

Thyroid Fna

Background: Thyroid fine needle aspiration (FNA) is currently the most acceptable method for evaluating thyroid nodules. Non-satisfactory sample is the main limitation of FNA. It has been shown that spinal needles can reduce the number of non-diagnostic samples. Objectives: In this study, we decided to compare the results obtained using spinal (stylet) needle and simple needle in thyroid nodule FNA according to the agreement between them and with the pathology results as the gold standard. Patients and Methods: Sampling of thyroid nodules of 156 patients was performed by a simple non-stylet 23 gauge needle (A) and a spinal 22 gauge needle with stylet (B). The samples were provided to the pathologist for blind examination. All samples were obtained by an expert radiologist and the pathology examination was also performed by a pathologist expert in thyroid gland diseases. Blind analysis was done using SPSS Statistics for Windows, version 16 (SPSS Inc., Chicago, Ill., USA). Results: The results of FNA with needles A and B were reported unsatisfactory in 11.51 (18 subjects) and 3.84 (six subjects), respectively (P = 0.01). The result in 63.46% (99 subjects) of the participants, in whom FNA was obtained by needle B was introduced as a better sample by the pathologist in comparison with 36.44% (57 subjects) (P < 0.001). Cancer was diagnosed in 9.56 and 7.66 of the samples yielded by needles B and A, respectively, which was not statistically significant (P = 0.54). There was also a significant relationship between thyroid imaging reporting and data system (TI-RADS) score and FNA result. Conclusion: A significant relationship between the adequate sampling results, the qualitative examination result, TI-RADS score and the needle type indicates the importance of needle type on the results of thyroid FNA. Using spinal (stylet) needles may reduce the number of non-diagnostic samples in fine needle aspiration of thyroid nodules and therefore, can have a better effect on the results of this method.

Background: Fine-needle aspiration (FNA) plays a fundamental role in determining the appropriate management for patients presenting with thyroid nodules. Aims: The aims of this study are to evaluate thyroid FNA test performance parameters through a cytohistological correlation. Materials and Methods: A retrospective analysis of all thyroid FNAs received over a period of 18 months was carried out. The findings were compared to their subsequent definite diagnoses on surgical specimens as well as to their follow-up repeat FNA results. A total of 499 thyroid FNAs were collected and reviewed against The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC). The percentage of each diagnostic category was calculated, and the implied risk of malignancy was determined by comparing the cytology results to their definite diagnoses obtained on the resection specimens. Analytical procedures were performed using Microsoft Excel. Results: Out of 499 thyroid FNAs, a benign interpretation was found in 273 patients (54.7%), atypia of undetermined significance in 81 (16.2%), follicular neoplasm in 20 (4%), suspicious for malignancy in 36 (7.2%), malignant in 32 (6.4%) and were nondiagnostic in 57 patients (11.4%). Only 101 patients (20.2%) underwent surgical resection and 47 (9.4%) underwent a follow-up FNA. After cytohistological correlation, FNA test performance, calculated by excluding the inadequate and undetermined categories revealed test sensitivity, specificity, and diagnostic accuracy of 95.6%, 54.8%, and 78.9%, respectively. The positive predictive value was 75.4%, and the negative predictive value was 89.5%. Conclusions: Our results are comparable to those previously published figures. The rate of atypia of undetermined significance/follicular lesion of undetermined significance is higher than what is currently recommended in TBSRTC.
