Abstract
INTRODUCTION High false-negative results have been reported for fine-needle aspiration (FNA) cytology in thyroid nodules. Fine-needle capillary (FNC) cytology is an alternative technique that prevents aspiration, reducing tissue damage. This study aimed to compare FNA and FNC in assessing thyroid nodules and in terms of their predictive role in the appropriate diagnosis of malignancy. METHODS This is a comparative prospective study conducted on 486 patients. FNA was performed in 235 patients during 2016 and 2017 and FNC in 251 patients during 2018 and 2019. The quality of cytological specimens was compared and then correlated with the final histopathological findings of 39 patients who underwent thyroidectomy. RESULTS Both groups were statistically similar regarding age and sex distribution. The FNA technique yielded significantly higher adequate specimens compared with FNC (p<0.001). Abundant blood in the background was found more frequently in the FNA technique (p<0.001). The sensitivity and specificity of FNA for malignancy diagnosis were both 100%, compared with 83.3% and 57.7% for FNC, respectively. CONCLUSIONS The two methods, FNA and FNC, did not differ in terms of overall quality. FNA was superior regarding consistency with the histopathological results and the ability to diagnose malignancy.

Comparison of Ultrasound-Guided Fine-Needle Cytology Quality in Thyroid Nodules with 22-, 23-, and 25-Gauge Needles. ACTA ACUST UNITED AC 2021; 2021:5544921. [PMID: 34211823 PMCID: PMC8205598 DOI: 10.1155/2021/5544921] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2021] [Accepted: 05/29/2021] [Indexed: 01/21/2023]
Abstract
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.

Abstract
Background To compare the sampling adequacy and diagnostic efficiency of ultrasound-guided fine-needle aspiration with 22-, 25-gauge needles and capillary sampling with 22-gauge needle in the biopsy of cervical lymph node. Methods A total of 130 cervical lymph nodes from 103 patients were consecutively included in the prospective study. Each suspected lymph node was aspirated with a 22-gauge needle, capillary sampled with a 22-gauge needle and aspirated with a 25-gauge needle. The adequacy rates and nondiagnostic rates of obtained specimen were calculated. Results Of the 130 suspected lymph nodes, there were 77 lymph nodes<6.0 mm and 53 lymph nodes≥6.0mm in the smallest dimension. Both FNA22G and FNC22G got significantly higher sampling adequacy than FNA25G for the total lymph nodes. For lymph nodes<6.0 mm, the sampling adequacy was significantly higher with FNA22G than with FNA25G for each parameter and the cumulative score (all P<0.05), while no difference were seen between FNA22G and FNC22G, and between FNC22G and FNA25G. There were higher nondiagnostic rates for FNA25G compared with FNA22G and FNC22G in all lymph nodes and in each size subgroups. FNA25G yielded more diagnostically inadequate specimens than FNA22G and FNC22G did in the total lymph nodes (P=0.002), in lymph nodes<6.0 mm (P=0.014), and in those ≥ 6.0 mm (P=0.000). Conclusions FNA22G and FNC22G obtained more diagnostically adequate specimens than FNA25G in cervical lymph nodes. FNA22G and FNC22G may be more suitable than FNA25G in diagnosing cervical lymph nodes. FNA22G and FNC22G may yield specimens with similar quality.

Abstract
OBJECTIVE Two different methods for fine needle aspiration biopsy (FNAB) of thyroid nodules (multi-pass conventional smear, MPCS; single-pass liquid-based cytology, SPLBC) were evaluated regarding the magnitude of nondiagnostic/unsatisfactory sampling ratio, and basic demographic and ultrasonographic (USG) factors to predict such outcome. METHODS One thousand FNAB patients were retrospectively assessed. Of them, 517 nodules were evaluated with the conventional smear method, and the rest were evaluated with liquid-based cytology method using the Bethesda System for Reporting Thyroid Cytopathology. FNAB technique had certain procedural differences for both pathological methods. For conventional smear, a modified "needle-only" technique with three independent passes was performed, whereas a single pass was used for liquid-based cytology. The reduction of nondiagnostic/unsatisfactory results constituted the basis of this study. Pathological results, therefore, were subgrouped under "nondiagnostic/unsatisfactory" (Category I), "benign" (Category II), and "atypia/neoplasia/malignancy" (Category III-VI). RESULTS Both FNAB groups were not statistically different or only slightly different regarding size (P = 0.196), echogenicity (P = 0.014), and the presence of echogenic foci (P = 0.11), therefore considered to have equal USG properties. In MPCS method, the nondiagnostic/unsatisfactory rate (i.e., Category I) was 24%. Other cytological results were as follows: Category II (67.1%), Category III-VI (8.8%). In SPLBC method, the nondiagnostic/unsatisfactory rate (i.e., Category I) was 14.5%. Other cytological results were as follows: Category II (77.6%), Category III-VI (7.8%). A significant difference was found between two sampling methods regarding pathological results (Independent samples t-test, P < 0.0001). The demographic and USG factors, considered in this study, did not offer a successful prediction of nondiagnostic/unsatisfactory outcomes. CONCLUSION SPLBC has significantly lower (14.5% vs 24%) nondiagnostic rate than MPCS, and higher 77.6% vs 67.1%) Category II rate than MPCS. This may point to the possibility that MPCS method undercategorizes many benign (i.e., Category II) nodules under nondiagnostic/unsatisfactory category. The success of the former is due to the elimination of confounding material during the process. Single pass, also, increases patient comfort and compliance, and has additional advantages for the interventionalist, as it obviates the need to smear aspirates. This dramatically decreases the actual duration of the biopsy procedure and is free of interventionalist expertise for smearing.

Abstract
OBJECTIVE OF THE STUDY To test whether a direct-on-site microscopic examination of fresh, unstained puncture slides by the radiologist decreases the rate of false-negative cases on ultrasound-guided fine-needle cytology of parotid gland masses. PATIENTS Thirty parotid gland masses from 28 patients were punctured under ultrasound guidance. The same group was used as its control group. METHODS After one or two passes, the material was spread on slides and air-dried (control group, without microscopic examination). For the study group, it was thus analyzed unstained under the microscope. A sample was considered adequate if at least six clusters of parotid cells were found per slide on at least two slides. For the study group, new punctures were obtained and slides prepared until this condition was fulfilled. RESULTS Of the 30 evaluated masses, 100% benefited from a cytological diagnosis after microscopy. Twenty-four were adequate in the control group, while 30 were adequate in the study group. The maximum number of punctures to obtain an adequate sample was six. On-site direct microscopy significantly increased the number of adequate specimens by 20% (P=0.03, CI [1.63-20%]). CONCLUSION Direct and systematic examination of slides by a radiologist avoided the risk of false-negative results caused by having insufficient sample material.

Abstract
Objective To evaluate the diagnostic validity of fine-needle capillary cytology (FNCC) in palpable tumours. Material and methods A retrospective, single-tray, cross-sectional diagnostic test study was carried out. We reviewed the cytological reports of the case files of the Cytology Unit of the Northern Regional Institute of Neoplastic Diseases (IREN) from January 2012 to December 2016. Results A total of 332 patients were selected, with an average age of 54.77 years (range 13-90 years); 61.4% of patients were female. The most frequent anatomical sites were lymph nodes (49.7%), thyroid (13.3%), breast (12.3%) and soft tissues (11.4%). Twenty-five cytologies did not have a histological correlation and six showed an atypical result. In the lymph node study, the most frequent pathology was metastatic carcinoma (49.7%), followed by lymphoma (13.3%). The FNCC had a sensitivity of 99.55%, a specificity of 98.77%, a positive predictive value of 99.55% and a negative predictive value of 98.77%. The positive likelihood ratio was 80.63%. Conclusions FNCC is a useful, safe, reliable and economical ambulatory technique with minimal complications and high diagnostic accuracy.

Abstract
Background. Fine needle aspiration cytology (FNAC) and fine needle nonaspiration cytology (FNNAC) are useful cost-effective techniques for preoperatively assessing thyroid lesions. Both techniques have advantages and disadvantages, and there is controversy over which method is superior. This meta-analysis was performed to evaluate the differences between FNAC and FNNAC for diagnosis of thyroid nodules. Methods. Primary publications were independently collected by two reviewers from PubMed, Web of Science, Google Scholar, EBSCO, OALib, and the Cochrane Library databases. The following search terms were used: fine needle, aspiration, capillary, nonaspiration, sampling without aspiration, thyroid, and cytology. The last search was performed on February 1, 2015. Results. Sixteen studies comprising 1,842 patients and 2,221 samples were included in this study. No statistically significant difference was observed between FNAC and FNNAC groups with respect to diagnostically inadequate smears, diagnostically superior smears, diagnostic performance (accuracy, sensitivity, specificity, negative predictive value, and positive predictive value), area under the summary receiver operating characteristic curve, average score of each parameter (background blood or clot, amount of cellular material, degree of cellular degeneration, degree of cellular trauma, and retention of appropriate architecture), and total score of five parameters. Conclusion. FNAC and FNNAC are equally useful in assessing thyroid nodules.

Abstract
A 55-year-old man presented with a 2-year history of right-sided epiphora and was referred to the Oculoplastic services for dacryocystorhinostomy. A 3-month progressive growth of a right medial canthal mass was found. MRI revealed an extraconal, lobulated, homogeneously enhancing mass in the lacrimal sac fossa with globe indentation and displacement supero-temporally. Following a transcanalicular needle biopsy which was suggestive of a carcinoma, he underwent medial orbitectomy and maxillectomy, through a lateral rhinotomy, with removal of puncta and canaliculi after ensuring no regional or systemic spread. The lacrimal sac tumor was encapsulated, extending superiorly above the medial canthal tendon and involving the nasolacrimal duct, and posteriorly along the medial orbital wall. After ensuring surgical margins were cleared of tumor infiltration, orbital reconstruction was performed with titanium plate and nasolabial flap. He has completed adjuvant radiotherapy with no evidence of tumor recurrence at 15 months of follow-up.

Abstract
PURPOSE The purpose of the present study was to integrate safety-engineered devices into outpatient fine-needle aspiration (FNA) biopsy of the thyroid in an interventional radiology practice. MATERIALS AND METHODS The practice center is a tertiary referral center for image-directed FNA thyroid biopsies in difficult patients referred by the primary care physician, endocrinologist, or otolaryngologist. As a departmental quality of care and safety improvement program, we instituted integration of safety devices into our thyroid biopsy procedures and determined the effect on outcome (procedural pain, diagnostic biopsies, inadequate samples, complications, needlesticks to operator, and physician satisfaction) before institution of safety devices (54 patients) and after institution of safety device implementation (56 patients). Safety devices included a patient safety technology-the mechanical aspirating syringe (reciprocating procedure device), and a health care worker safety technology (antineedlestick safety needle). RESULTS FNA of thyroid could be readily performed with the safety devices. Safety-engineered devices resulted in a 49% reduction in procedural pain scores (P < 0.0001), a 56% reduction in significant pain (P < 0.002), a 21% increase in operator satisfaction (P < 0.0001), and a 5% increase in diagnostic specimens (P = 0.5). No needlesticks to health care workers or patient injuries occurred during the study. CONCLUSIONS Safety-engineered devices to improve both patient and health care worker safety can be successfully integrated into diagnostic FNA of the thyroid while maintaining outcomes and improving safety.

Abstract
BACKGROUND Thyroid fine-needle biopsy (FNB) is a simple, reliable, inexpensive, and generally safe diagnostic procedure in the management of thyroid nodules. Local pain and minor hematomas are the most common clinical complications, and hemorrhage and fibrosis the most common histological alterations after thyroid FNB. FNB can also trigger biochemical alterations in serum, since it may destroy thyroid follicles. In this review we summarized the biochemical alterations in serum that occur after diagnostic thyroid FNB, aiming to review information that would be potentially useful in interpreting thyroid tests in patients who recently had a thyroid FNB. SUMMARY Computerized advanced search for primary evidence was performed in the PubMed (Public/Publisher MEDLINE) electronic database not limited by publication time and English language. An increase in serum thyroglobulin (Tg) ranging from 35% to 341% occurs in 33-88% of patients subjected to FNB. Serum Tg concentrations typically return to baseline about 2-3 weeks after FNB. The abrupt release of Tg after FNB may induce the production of autoantibodies to Tg and thyroid hormones in a minority of patients. There is little information on the effect of FNB on autoantibodies to thyroid peroxidase. No changes seem to occur in thyroid-stimulating hormone, total thyroxine, free thyroxine, free triiodothyronine (T3), or reverse T3, while controversy exists for T3. CONCLUSIONS The degree of increase in serum Tg after FNB is highly variable and not a predictor of whether the biopsied nodule is benign or malignant. The increase or development of Tg autoantibodies that occurs in some patients does not appear to be of clinical significance. Development of autoantibodies to thyroid hormones may be more likely in patients whose biopsied nodule is benign than malignant, but further studies are required to confirm this. If changes in serum thyroid-stimulating hormone or thyroid hormones are noted in a patient with a history of a recent fine-needle aspiration, they should be investigated since they are not likely to be related to the biopsy.

Abstract
Fine-needle aspiration biopsy represents the most reliable test for cytologic evaluation of thyroid nodules. However, inadequate samples may occur leading to a repetition of the procedure with the consequence of patients' discomfort and poor compliance. In this paper, we present results from biopsy of thyroid nodules obtained by combining: (1) ultrasound (US) guidance, (2) no-aspiration technique, and (3) on-site review of specimens. A total of 465 nodules were biopsied in 307 patients. Solitary nodules and multinodular goiter were present in 36.8% and 63.1% of patients, respectively. After collection, each sample was smeared in duplicates, one of which was stained with hematoxylin and checked on-site by a cytopathologist. In cases of inadequate smears, biopsies were immediately repeated. All slides were then processed for final cytologic results, which were reported as benign in 427 nodules (91.8%), malignant in 12 nodules (2.5%), with follicular proliferation or suspicious for malignancy in 23 nodules (4.9%). Inadequate final cytology was reported in 3 nodules (0.6%). No statistically significant relationship was found between nodule size and adequacy of specimens. We conclude that the combination of US guidance, capillary collection with no-aspiration technique, and on-site review of slides, characterizes an advantageous method for thyroid nodule fine-needle biopsy.

Abstract
The scoring system developed by Mair et al. (Acta Cytol 1989;33:809-813) is frequently used to grade the quality of cytology smears. Using a one-factor analytic structural equations model, we demonstrate that the errors in measurement of the parameters used in the Mair scoring system are highly and significantly correlated. We recommend the use of either a multiplicative scoring system, using linear scores, or an additive scoring system, using exponential scores, to correct for the correlated errors. We suggest that the 0, 1, and 2 points used in the Mair scoring system be replaced by 1, 2, and 4, respectively. Using data on fine-needle biopsies of 200 thyroid lesions by both fine-needle aspiration (FNA) and fine-needle capillary sampling (FNC), we demonstrate that our modification of the Mair scoring system is more sensitive and more consistent with the structural equations model. Therefore, we recommend that the modified Mair scoring system be used for classifying the diagnostic adequacy of cytology smears. Diagn. Cytopathol. 1999;21:387-393.
