52, No. In our thyroid FNAC practice, Bethesda Category III III • The provisional goal of limiting AUS/FLUS interpretations to 7% of all thyroid FNA interpretations is increased to 10%. The Bethesda atlas itself, which Crippa and Mazzucchelli did not have access to when they wrote their letter, defines and illustrates the morphologic criteria for the AUS/FLUS category. Methods All … Shi X, Liu R, Basolo F, Giannini R, Shen X, et al. FN/SFN 15-30% Lobectomy V. Suspicious Combination of ultrasound and molecular testing in malignancy risk estimate of Bethesda category IV thyroid nodules: results from a single-institution prospective study. To date there have been few studies to determine whether these predictions are widely applicable. In contrast, the highest frequency in category 4-IV was 62/180 for TIRADS 4 versus 41/180 for Bethesda IV. Epub 2017 Apr 19. Suspicious for follicular cancer… None of the patients classified as TIRADS 2 were rated as Bethesda IV or V. Thus, Thy3 requires a separate study. Malignancy rates for Bethesda category III and IV thyroid nodules that require surgery are approximately 25% and 27.6%, respectively, according to the results of a retrospective study published in BMC Endocrine Disorders. The aim of Bethesda category 4 is to identify a nodule that might be a follicular carcinoma. Stage II (T2, N0, M0): The tumor is more than 2 cm but not larger than 4 cm across and has not grown outside the thyroid (T2). The 2017 revision reaffirms that every thyroid FNA report should begin with one of six diagnostic categories, the names of … 3 An “atypical” category has been in use in 4 Indetermi-nate, 4. 2016 Jan. 101 (1):264-74.. . This study aims to determine the utility of the Bethesda category and its association with BRAF mutation in prediction of the papillary thyroid cancer (PTC) stage. The Pap Test and Bethesda 2014/Nayar and Wilbur Cancer Cytopathology May 2015 273 task force working groups. 28 On the other hand, FTC represents 28.8% of Bethesda IV malignant lesions while only 2.4% of malignant lesions are category III. 4 Ancillary molecular testing of indeterminate thyroid nodules Bethesda Category V is considered 60% - 75% likely to be malignant. (Table 3 ) The highest concordance was found for categories TIRADS 2-Bethesda II (23.33%). Class 4. Diagn Cytopathol. The most widely utilized system for reporting thyroid FNA results is the Bethesda System, which includes predicted malignancy rates for each FNA category. Stage I (T1, N0, M0): The tumor is 2 cm or less across and has not grown outside the thyroid (T1). AUS/FLUS 5-15% Repeat FNA IV. Management of patients who have atypical thyroid nodules. The uncertainty is when there are features that may be cancer, or may be benign, as found in the Follicular Variant of Papillary Carcinoma that can look benign, and vice-versa, benign cells that look like FVPTC. The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) established a standardized, category-based reporting system for thyroid fine-needle aspiration (FNA) specimens. The 6 general diagnostic categories are shown in bold type in Table 1 . M Marina Dipartimento di Medicina e Chirurgia, SSD Medicina Interna Ad Indirizzo Onco-Endocrinologico, Università di Parma-Azienda Ospedaliero-Universitaria di Parma, Parma, Italy. Report. This category means that no signs of cancer, pre-cancer, or other significant abnormalities were found. 29 Additionally, the malignancy rate of Thy4 is much 30 1. 3.4 Malignancy rate and composition of thyroid nodules according to subtype of Bethesda category III Subsequently, we investigated the difference in malignancy rates among the subtypes (cytologic atypia or architectural atypia) of thyroid nodules with AUS/FLUS in each category of US-RSS. J Clin Endocrinol Metab. It has not spread to nearby lymph nodes (N0) or distant sites (M0). Among all the cases diagnosed initially as AUS/FLUS (Bethesda category III), 9 (9.3%) cases were diagnosed as papillary thyroid carcinoma. Bethesda system suggests a six category classification system to report thyroid FNAB results: 1. They are reportable as FN or SFN. WHAT ARE THE IMPLICATIONS OF THIS STUDY? 1% to 4% Repeat FNA with ultrasound Bethesda category may help to predict the most likely histologic subtype of thyroid cancer, but it does not have any prognostic significance once the histologic diagnosis is known. The Bethesda system for reporting thyroid cytopathology (TBSRTC) has attempted to standardize thyroid fine needle aspiration cytology (FNAC) reporting internationally into six diagnostic categories and help in clinical decision making. S3.01 The general classification (category descriptor) of the aspirate must be recorded. Because many different results are placed into Bethesda category III, the clinical management of patients with these nodules is varied, and there is no consensus as to the best approach to management. Positive fore cancer – 5.4% (ranging between 2-16%) – of those 98.6% were cancerous at final pathology. There may be findings that are unrelated to cervical cancer, such as signs of infection with yeast, herpes, or Trichomonas vaginalis (a type of sexually transmitted disease), for example. For clarity of communication, the Bethesda System for Reporting Thyroid Cytopathology recommends that each report begin with a general diagnostic category. Non-diagnostic/ unsatisfactory, 2. thyroid Bethesda category 5 Tuesday 23 August 2016 See also thyroid FNA Open references The Bethesda System for Reporting Thyroid Cytopathology: Interpretation and Guidelines in Surgical Treatment.

TBSRTC v1 overview Diagnostic Category Risk of Malignancy Usual Management I. ND/UNSAT 1-4% Repeat FNA II. This is not aligned with the estimated MR in this Bethesda category ( 2 ) and may have influenced some of the results. CS3.01a Following general categorisation, a specific diagnosis must be stated, favoured or suggested, where applicable. Cytology The cytopathological reports were issued by a path-ologist, following the Bethesda classification according to the literature [1, 4]. Background Fine needle aspiration (FNA) of thyroid nodules is a cornerstone of surgical decision making in thyroid cancer. 2017 Jul;45(7):604-607. doi: 10.1002/dc.23734. To illustrate the effect of this change, both Strickland et al 26 and Faquin et al 27 showed that the overall percentage of cancers in Bethesda categories 2, 3, 4, and 5 would be markedly reduced if all lesions that were previously 26, Benign 0-3% Clinical follow-up III. RESULTS: There were 87 (8.9%) Bethesda category III cytologies (34 CC, 53 AA). The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) established a standardized, category-based reporting system for thyroid fine-needle aspiration (FNA) specimens. Affiliation 1 Division of Endocrine and Minimally Invasive Surgery, Department of Surgery, New York Presbyterian Hospital/Weill Cornell Medical College, New York, NY 10065, USA. Papillary Thyroid Cancer in Patients 55 years and Older. New oncologist joins practice in Bethesda Oncologist and hematologist Dr. Bruce Cheson has joined The Center for Cancer & Blood Disorders in Bethesda, the … The categorizing of FNAB results according to Bethesda system was different among medical centers. Among all patients with DTC included in the cohort, the Bethesda II was the most frequent category found in preoperative FNAs (29.4%). agnosed with Bethesda III and IV with no follow-up data. Benign/Non-cancerous, 3. Bethesda Diagnostic Category Risk of Malignancy Usual Management I Non-diagnostic or unsatisfactory Cyst fluid only Virtually acellular specimen Other (obscuring blood, dotting artifact, etc.) Second cytologies were performed in 23 patients (16 with CA, 7 with AA), and a benign result was found in 68.7% of CA and 71.4… Methods A prospective study analyzed patients who had ultrasound-suspicious thyroid nodules, underwent FNA and cytological examination, and were classified according to the Bethesda system. Follicular carcinomas have cytomorphologic features that distinguish them from benign follicular nodules but do not permit distinction from a follicular adenoma (FA). Thyroid cancer detection rate and associated risk factors in patients with thyroid nodules classified as Bethesda category III Radiology and Oncology, Vol. Conclusion: Diagnostically, we almost meet the international standards of designating
