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.

Abstract Introduction Fine Needle Aspiration Cytology (FNAC) is the best diagnostic tool for evaluating thyroid nodules pre-operatively. The Bethesda System for Reporting Thyroid Cyto-pathology (TBSRTC) in America and THY classification in Europe are standardized reporting systems for thyroid FNAC specimens using six categories. As compared to the first edition in 2009, a second edition of TBSRTC published in 2017 has revised risk of malignancy (ROM) for these categories, with focus on atypia of unknown significance (Thy3A) upgraded to 10-30% from previously 5-15%, and suspicion for follicular neoplasm (Thy3F) 25-40% from previous 15-30%. Method A three-year audit of thyroid surgeries performed in two high volume thyroid institutions from January 2016 to September 2019, was performed retrospectively. The FNAs were performed by thyroid specialist radiologists with a cytopathology technician in attendance for rapid on-site evaluation and reported as per TBSRTC and Thy classification, by a Consultant Cyto-pathologist from a single institution. Result A total of 702 patients were examined. There were 552 patients who had corresponding FNAC prior to surgery (mean age 53.6 years, females 79%). The rates of malignancy were, Thy1: 9.3%, Thy2: 4.6%, Thy3A: 10.8%, Thy3F: 28.7%, Thy4: 82.3% and Thy5: 100%. The main types of thyroid malignancy were Papillary (73.6%), Follicular (14.1%), Medullary (4%), Anaplastic (4.7%) and others (3.6%). Conclusion Pre-operative diagnosis of thyroid nodules using TBSRTC was comparable and the criteria helped avoid misinterpretation of results. Our results were comparable with the risk of malignancy in 2009 edition of TBSRTC, as compared to the 2017 revision. Take-home message Pre-operative diagnosis of thyroid nodules using The Bethesda System for Reporting Thyroid Cyto-pathology (TBSRTC) was comparable and the criteria helped avoid misinterpretation of results. Our results were comparable with the risk of malignancy in 2009 edition of TBSRTC, as compared to the 2017 revision.

Indeterminate Cytology

Objective: Although fine needle aspiration cytology (FNAC) is the most reliable, safe and accurate method for the clinical management of abnormal thyroid nodules, 5%-15% of cases lead to indeterminate diagnoses and surgery is the recommended practice for them as they may be malignant. Nevertheless, the majority of cases with indeterminate cytology are benign, so the risk of unnecessary surgery is significant. In our study we combined FNAC and scintigraphy in order to reduce the number of inappropriate surgeries. Subjects and Methods: From 219 patients with thyroid fine needle aspiration cytology 33(9 males and 24 females) aged 18-73 years, had indeterminate FNAC diagnoses and were referred for scintigraphy. Surgery was performed in all cases. The results of FNAC, scintigraphy and histology were collected and compared. Results: From 33 cases with indeterminate cytology 32 had a benign histological diagnosis and only one was malignant (follicular Ca). That case had a positive scan. All cases with negative thyroid scans (29/33) were benign. False positive scans were 3, whereas one scan was true positive with final diagnosis follicular carcinoma. Conclusion: This study showed that combining the FNAC with the thyroid scintigraphy in cases of thyroid nodules with indeterminate cytology it is possible to reduce the number of inappropriate surgeries from 32 to 3.
