Maligniteyi Öngörmede Tiroid Nodüllerinin Ultrasonografik Özellikleri ve Sitopatoloğun Rolü

Amaç: Tiroid ince iğne aspirasyon biyopsisi ile değerlendirilmesi gereken doğru nodülleri belirlemek ve gereksiz işlemlerden kaçınmak çok önemlidir. Bu çalışmada tiroid ince iğne aspirasyon biyopsi sonuçları ile ultrasonografik özellikler arasındaki ilişkiyi ve patoloğun rolünü incelemeyi amaçladık. Gereç ve Yöntemler: Çalışmaya tiroid ince iğne aspirasyon biyopsisi yapılan 458 hasta dahil edildi. Ultrasonografik özellikler (ekojenite, şekil, vaskularizasyon, sınır ve kalsifikasyon) ve biyopsi sonuçları ile patolog faktörü arasındaki ilişki retrospektif olarak değerlendirildi. Bethesda VI (malign) sonucu olmadığı için 5 alt grup arasında analizler yapıldı. İİAB işlemleri patoloji sonuçları açısından yetersiz, benign, önemi belirsiz atipi/önemi belirsiz folliküler lezyon, foliküler neoplazi ve malignite şüphesi olarak değerlendirilmiştir. Bulgular: Düzensiz sınır, hipoekojenite, mikrokalsifikasyon varlığı, ön-arka çapın transvers çapından büyük olması (AP> T) Bethesda alt grupları arasında istatistiksel olarak farklı bulundu. (ekojenite için p

Ultrasonographic Characteristics of Thyroid Nodules in Predicting the Malignancy and the Role of the Cytopathologist

Aim: It is very important to determine the correct nodules which should be evaluated with thyroid fine- needle aspiration biopsy (FNAB) and avoid unnecessary operations. In this study, we aimed to analyze the relationship and the compatibility between thyroid FNAB results with ultrasonographic features and the role of the pathologist who examines the specimens. Material and Methods: 458 patients with nodules who underwent FNAB were included in the study. The relationships between the ultrasonographic features (echogenicity, shape, margin, vascularization and calcification) and biopsy results and, the factor of the pathologist were evaluated retrospectively. Since there was no Bethesda VI (malignant) result, analyzes were made among 5 subgroups. FNAB procedures were considered as, inadequate or nondiagnostic, benign, atypia of undetermined significance (AUS) or follicular lesion of undetermined significance (FLUS), follicular neoplasia and suspicion of malignancy. Results: Solid internal structure, irregular margin, hypoechogenicity, presence of microcalcification, nodules with taller than wide (AP> T) were found significantly different between the subgroups of Bethesda classification system (p
