Abstract

Aim: The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) is employed to evaluate the cytopathology of thyroid nodules. The nodules reported as categories 3 and 4 constitute risk of malignancy at varying rates. This study aims to document the amount of actual malignancy rates in TBSRTC category 3 and 4 thyroid nodules.

Materials and Methods: Patients having thyroid nodules with reported Bethesda category 3 and category 4 results on fine needle aspiration biopsy who subsequently underwent thyroidectomy between January 2013 and December 2018 were retrospectively analyzed.

Results: Seventy-two patients and 72 nodules were included in our study. The Bethesda category 3 group consisted of 40 patients and 40 nodules. The histopathologic result was reported as benign in 23 (57,5%) patients and malignant in 17 (42,5%) patients. The Bethesda category 4 group covered the remaining 32 patients and 32 nodules. Histopathologic results were reported as benign in 12 patients (37,5%) and malignant in 20 patients (62,5%).

Conclusion: Bethesda category 3 and 4 nodules bear varying rates of malignancy risk, and this rate increases with the presence of additional incidentally detected malignancies.

Tiroid Sitopatolojisini Raporlamak için Bethesda Sistemi'ne Göre Kategori 3 ve Kategori 4 Tiroid Nodüllerinin Malignite Oranları

Abstract

Amaç: Tiroid nodüllerinin sitopatolojisini değerlendirmek için kullanılan Tiroid Sitopatoloji Raporlaması için Bethesda Systemi’ne (TSRBS) gore kategori 3 ve kategori 4 olarak raporlanan nodüller değişik oranlarda malignite riskleri taşır. Bu çalışmanın amacı TSRBS kategori 3 ve 4 tiroid nodüllerinde malignite oranlarını saptayıp değerlendirmektir.
Gereç veYöntemler: Ocak 2013- Aralık 2018 tarihleri arasında ince iğne aspirasyon sonuçları Bethesda kategori 3 ve kategori 4 olan, sonrasında tiroidektomi uygulanan hastalar retrospektif olarak değerlendirildi.
Bulgular: Çalışmamıza 72 hasta, 72 nodül dahil edildi. Bethesda kategori 3 grubunda 40 hasta,-40 nodül mevcuttu. Histopatoloji sonucu 23 (%57,5) hastada benign, 17 (%42,5) hastada malign olarak raporlandı. Bethesda kategori 4 grubunda 32 hasta-32 nodül mevcuttu. Histopatoloji sonucu 12 hastada (%37,5) benign, 20 hastada (% 62,5) malign olarak raporlandı.
Sonuç: Bethesda kategori 3 ve 4 nodülleri değişik oranlarda malignite riski taşır ve insidental olarak saptanan maligniteler ile de bu oran artar.
