Improving Diagnostic Performance for Thyroid Nodules Classified as Bethesda Category III or IV: How and by Whom Ultrasonography Should be Performed
2020
Background: The purpose of this prospective study is to evaluate if the association of Bethesda system and a 3-categories Ultrasonography (US) risk stratification system proposed by the American Association of Clinical Endocrinologists/American College of Endocrinology/Associazione Medici Endocrinologi improves the performance of cytology alone in III or IV categories and if further variables such as US provider (radiologist; endocrinologist, or endocrine surgeon both coming from a dedicated team) influence the accuracy of the diagnostic. Methods: 570 consecutive patients with complete clinical records, affected by Bethesda III or IV nodules, have been addressed to two public referral surgi…
Vairogdziedzera mezglu analizēšana, izmantojot attēlu diagnostikas klasifikācijas un datu sistēmu (TIRADS), un salīdzinot ar Bethesda sistēmu
2017
Vairogdziedzera attēlu diagnostikas klasifikācijas un datu sistēma (Thyroid Imaging Reporting and Data System, TIRADS) ir klasifikācijas sistēma, kas iedala mezglu malignitātes riskus. Katra kategorija reprezentē vairogdziedzera mezgla malignitātes risku. Tā izveidota ar mērķi uzlabot reaģēšanu un izmaksu pārvaldību, samazinot vajadzību pēc ar tievu adatu aspirācijas biopsijas pacientiem, kuriem ir vairogdziedzera mezgli. TIRADS sistēma ir riska novērtēšanas sistēma vairogdziedzera audu bojājumu klasificēšanai. TIRADS novērtējums sniedz informāciju par vairogdziedzera struktūru, malignitātes risku un klasifikāciju. Bethesda sistēma vairogdziedzera citopatoloģiju novērtēšanai ir vairogdziedz…
Impact of the Hypoechogenicity Criteria on Thyroid Nodule Malignancy Risk Stratification Performance by Different TIRADS Systems
2021
Background: Various Thyroid Imaging and Reporting data systems (TIRADS) are used worldwide for risk stratification of thyroid nodules. Their sensitivity is high, while the specificity is suboptimal. The aim of the study was to compare several TIRADS systems and evaluate the effect of hypoechogenicity as a sign of risk of malignancy on the overall assessment of diagnostic accuracy. Methods: The prospective study includes 274 patients with 289 thyroid nodules to whom US and risk of malignancy were assessed according to four TIRADS systems—European (EU-TIRADS), Korean (K-TIRADS), TIRADS by American College of Radiology (ACR TIRADS), and modified Kwak et al. TIRADS (L-TIRADS) systems, in which …
Atypical squamous cells of undetermined significance-favour reactive compared to atypical squamous cells of undetermined significance-favour dysplasi…
2005
Abstract Background and objectives: The current study compared the cervical cytological sub-category “atypical squamous cells of undetermined significance-favour reactive (AFR)”, recently recommended to be eliminated by the Bethesda system, to the sub-category “atypical squamous cells of undetermined significance-favour dysplasia (ASC-US)”, in terms of prevalence of coexistent squamous intraepithelial lesions of either low-grade (LSIL) or high-grade (HSIL) and rate of human papillomavirus (HPV) infection. Study design: One hundred women with AFR and 100 with ASC-US were consecutively included in the study. All patients underwent colposcopy, followed by biopsy when necessary, and were screen…
